The woman who said the current couldn't flow without a complete circuit was technically correct... she simply didn't know that that base of the bulb could be used as a connection. Simply a misunderstanding of the properties of the bulb as opposed to electrical current theory. This is a prime example of education vs experience in the field.
I don't think it's failure to understand the properties or construction of the bulb at all. I suspect that had she been given a 2nd wire she would have immediately connected it to the light bulb and battery correctly (as would several of the others). The problem here is not failure to understand how the most basic electrical circuit works, but failure to adapt when a simple problem is presented in a non-standard way. People just do not visualize a light bulb (or motor or almost anything else) in direct contact with its power source. I do think this non-adaptability (related to poor critical thinking) is a real problem, but the video misrepresents it.
Blake Marshall When you connect the end of the bulb you basically complete the circuit. And I think she was an Indian. And there was another genius who was a Black person if you will.
"In their classic paper Perception in Chess, Chase and Simon reported on a study that compared the abilities of experts and novices to remember the positions of pieces in chess. *When pieces were arranged on the board as they might be during a game*, the experts' memories were far superior to the novices'. When the pieces were arranged randomly, there was little difference between the memories of the experts and the novices. The traditional interpretation of this result is that an expert's memory is not inherently better than a novice's but that the expert has a knowledge structure that helps him or her remember particular kinds of information. When new information corresponds to the knowledge structure -- in this case, the sensible placement of chess pieces -- the expert can remember it easily. When new information doesn't correspond to a knowledge structure -- the chess pieces are randomly positioned -- the expert can't remember it any better than the novice. A few years later, Ben Shneiderman duplicated Chase and Simon's results in the computer-programming arena and reported his results in a paper called Exploratory Experiments in Programmer Behavior. Shneiderman found that when program statements were arranged in a sensible order, experts were able to remember them better than novices. *When statements were shuffled, the experts' superiority was reduced.* Shneiderman's results have been confirmed in other studies. The basic concept has also been confirmed in the games Go and bridge and in electronics, music, and physics." src. CodingHorrors
Yes, as indicated from 1:46 onward, what he recognised was that he needed more information about the battery and the bulb to answer Yes or No to the question. The video cheats by not showing people wiring the circuit correctly but still inevitably failing to light the 120v bulb with the 1.5v battery- except the cheat is, as most of the comments sadly illustrate, part of the education. If people don't consider all aspects of the situation (including, in this case, the fact that only the "maybe" guy was shown succeeding with a bulb of more suitable voltage rating) they will get the answers wrong.
No, the question was whether they could light a light-bulb with a battery and a wire. It doesn't matter that they weren't able to light that light-bulb with that battery and that wire.
It absolutely does matter, because the full correct answer to the question would be something like: "Yes, IF the battery provides a suitable voltage to make the bulb glow in the visible spectrum, AND the wire is long enough to connect the further terminal of the battery to the bulb, AND the bulb is a working light-bulb, as opposed to, for example, a tulip bulb".
No the general statement contains all the subset possibilities. Proving that birds can fly does not entail proving that every bird can fly. Proving that two or more birds can fly would prove the statement, that birds can fly. If you try to expand the many influences that you are talking about, then you can go further into if the wire is too resistant to current, if the wire is conductive at all, if the surroundings can transmit electromagnetic waves, if you are talking about the moment in which the circuit is connected since inductance can prevent the current from immediately appearing, if the questioned does not have a seizure while attempting to do so. Being able to light a light-bulb in any situation proves the statement of yes to the question, "do you think you could light a bulb with a battery and wire?" One instance in which they cannot, does not disprove the possibility that they can. If that were the case, then all laws of physics would be "disproven." If anybody is wrong, the creators of this video are in the wrong for not displaying the correct way to light the light-bulb with that set of equipment, if there even was a way. By your logic, I could ask them the question, then immediately shoot them on the spot. Therefore their statement would be wrong because they couldn't prove it using the equipment I was about to provide them.
Also, it is the question that needs fixing. "Do you think you could light a bulb with a battery and wire?" Should be "Do you think you could light THIS bulb with THIS battery and THIS wire?" Without specifying, the statement defaults to the general, and you just become an idiot that is trying to make graduates look like idiots with your flawed logic. If you tried to do this as a test for something like the SAT/GMAT/whatever, you would get sued and lose your job.
The guy who said, "maybe" paid the most attention in class. All of my engineering professors (sadly, I'm not an MIT alum) told us the answer to ANY engineering question is almost always, "it depends."
How to create a video like this one: Ask person after person to try to complete a task, knowing that some proportion will fail. Stop when you have recorded as much footage of failure as you need. Omit successes when you edit your video so that the failures seem more frequent than they are. Release the video and see how much it provokes its audience.
C Doyle The idea is that the task being asked requires much less intelligence than MIT graduates are given credit for. Anyone that has passed basic high school physics should be able to light a damn bulb.
They showed some of them succeeding but who cares about what they actually did, YOU FEEL WRONGED EVEN THOUGH THERE'S NO EVIDENCE OF IT! THE OUTRAGE!!!! HOW COULD THEY!?!?
Dude, have you any idea what you need to score in high school sciences and maths to be considered for MIT? I don't think there is a single student in my grade 12 physics class in my town that couldn't do it. Then you have some dumbass saying she was a mechanical engineer and not a electrical one? Holy shit!! And she'll have employers lining up with signing bonuses to hire her.
An "engineer", no matter from which university from which country, who can't light up a bulb with a wire and a battery, is too much of disgrace for that student and for that university and he hasn't deserved his graduate. It's just like as if a math graduate wouldn't be able to prove the pythagoras formula of a²+b²=c², because both are stuff, that you learn at school and which are basic for that study.
1) Question is misleading. If it was the right bulb, they could have done it. Battery is too weak for this kind of bulb 2) We only saw students who have failed. What about them who gave the right explanation why is it not working ? 3) Typical TH-cam video. Only clicks, shares and comments matters.
+Bon Bon Why do all MIT graduates need to construct the circuit that lights a bulb without instructions? I think the large majority of people maybe 80%+, have never had to work with bare wire without instructions. And if they did, the MIT grads could quickly learn how to do it.
timithy4569 Because MIT stands for Massachusetts Institute of *Technology* :P They don't need to deal with bare wire all the time, but they at least should know how to deal with it when they face such problems. (And they _will_ face!) If you only learn how to play with toys made by other people smarter than you, then you're not really that smart. One day there might be no smart people and their toys around and what then? You would have to be smart enough to build such toys yourself in order to do something more high-level next. Or your fancy toy may break and you will have to fix it. That's what engineers do, isn't it? :q
007K an AC lightbulb? they don't exist, either a lightbulb or an LED. An incandescent lightbulb works with both AC and DC circuits, a diode works only with properly configured DC circuits. Also the bulb looks an awful lot like a lightbulb from a cheap bike light or an internal light in a car. in which case it would be 12v, and 1.5v would be more than enough to light it.
Exactly! I always wondered why don't ,we as people, ask every candidate should be an engineer as a requirement? May be the world would focus on real issues rather than the politics we are blinded with currently.
No, because not every person in the world is an engineer. Let's ask you about the strategical impact of the Northern European plain in both world wars, how about that ?
I've been a mechanical engineer working in silicon valley for over 25 years. I never understood why they can't teach these kids basic things instead of putting emphasis on calculus and thermo etc. which I have never used my whole career! Most of what they pay you for in the industry is to solve problems that no answer exists yet. You find the answer and tell the world what you find. Its' called Innovation. The engineering curriculum needs some serious updating as it is the same as is was in my time in the 80's! Teach them how to put things together, and produce designs that can be manufactured. There's wayyy too much theory and not enough real world working knowledge. Most of the new grads feel great about themselves at first with all their knowledge they picked up in college only to slowly discover over the years that you use very little if any of it.
If they are engineers they obviously will be able to do it. But if they are computer science or finance then they will more than likely not know how to.
Frankly, this is the type of thing you should be able to do in 3rd grade. They don't need their degrees to buy groceries or do the dishes and they certainly don't need their degrees to complete an electrical circuit. This is not about the degree, it's about the foundation that the degree is built on.
Sure, there are lots of things we should consider 'basic knowledge' that you should get from a modern education, but it really is unreasonable to expect everything to sink in for everyone - if you look hard enough there will be people that don't know pretty basic facts. We can bemoan the fact that the education system is horrible, wasn't it so much better in the old days, you don't learn anything at university ... etc etc, but really it's not true: society hasn't collapsed into a bunch of idiots, we are going foward faster and faster and things are way way better than they were in the 'old days'. It's just silly to expect every single person to know how to make a simple electric circuit, even MIT graduates. Some people don't know how to cook food, some people don't tie their shoes properly - well ok, but overall things are fine. If they were electrical graduates, I'd be more worried - but the people that say 'you don't learn anything at university' have completely missed the point of university (or they were terrible students, or a terrible university)
"Do you think you could push a compact car down a hill?" "Of course." *Supplies an 86 Honda Civic full of cement with no wheels* _"There you go, M.I.T. Students are stupid."_
DOUGLAS SCOTT Actually the light bulb problem has no tricks at all. It's simply assessing their understanding of a basic closed circuit. To discover their are MIT grads unable to solve this basic problem implies the teaching is fundamentally ineffective.
Arif K How many volts is a standard Candle Bulb? How many volts can a D-cell battery output? Please link to us a 1.5v Candle Bulb of the same size in this video from any manufacturer. The only person who lit up a bulb, used a tiny DC compliant torch bulb, guess what it was designed to run on? My point still stands, you just do not understand both Physics and sarcasm.
They are not stupid because they could not light up the >=20W light bulb. They are stupid because most of them could not even close the circuit. And they didn't understand why it would not light up even if they would have closed the circuit. Thats two basic things they should have known. I knew this when I was 8 or 9 . The guy that was shown with a small bulb was the one that said "maybe", because he understood that he needed more information about the battery and bulb.
Lmao, Hakon is right, half the kids don't even put the wire to both ends. Its like they really just dont understand how a battery works. Oh but no a rich Ivy league school could never have dumb ass kids with rich parents. Its just cherry picking, yes :^)
It's in no way related to what they are worth. Harvard Professor's saying that '...everything else that's built on it is questionable' is disappointing. It's like for Bill Gates to be Bill Gates, he needs to be able to fix my neighbor's crappy laptop.
You are missing the point about Bill Gates. He is not as brilliant as his wealth would suggest. He is a leading philanthropist because of a fortunate combination of circumstances and not necesarily because he is a great person.
Bill Gates did not invent a technology. His company wrote an operating system (software) and made a deal with IBM to use it on their PC's. Given the computer-craze that kicked shortly there-after, it was a bit like having a patent on air. Not to say that Microsoft did not in some way contribute to the computer market, but it was more IBM that invented technology.
Electricity/electronics is one of those things with a tremendous chasm between "book learning" and "practical experience." To answer even the simplest questions about what will happen if certain components are connected, etc., (much like the question in the video), you are MUCH better off if you have "played around" with lots of circuits and building and modifying common functional circuits. Even lab classes don't really help. You have to spend time, on your own, really working through the practical realities...
Yup, my train of thought as well. I was less surprised at their inability to figure it out and more amazed that they gave some bullshit excuses or even said they could in the beginning. Instead of thinking to themselves, well, can I do this?
Nah, these days everything is modular so if you focus on your circuit it is simple. Systems engineers will focus on everything working together as long as you take the necessary design decisions. I think they were just more caught off guard. Expecting to be interviewed about how it feels to graduate from the most prestigious uni in the world, but to see they are being asked a simple question in a degrading way. I doubt they are stupid. That is a fallacy. This is more insight into human psychology.
As electrical engineer I can say that this kind of question is completly wrong and misleading. What is a light bulb and what's a battery? Neither of these say anything about the power supply and the load except that we have DC power supply and that the load suppose to lit. This question cannot be answered correctly except: I don't have enough data to judge. But it also says something about them as young engineers, they don't have that habit to look for needed data, to solve issues from the very beginning. They just blindly say yes or no without having proper data to answer. Another thing is that asking mechanical engineer about electricity is not a good idea. There's a reason why people get specialized education. That's because no one can be great at everything or even lots of stuff. Not enough life, not enough time. But one can be great at one discipline. But we got to the point where people have good knowledge about one discipline but they don't know the first thing about anything else. And people with varied knowledge are really needed right now. I don't know about MIT but when I was getting education at my uni of tech, 90% of the program was pure theory. Now looking at it after a few years, you are not engineer because you got a degree. Engineer is a diploma + a few years of experience in your discipline. Then you can call yourself an engineer. I have a few friends that have the very same diploma as I do but they wouldn't be able to do anything practical, all they can do is sitting in front of computers.
yo... my dude. they didn't just ask the question... they gave them the battery and the bulb and the wire. And they couldn't figure out how to do it. It's something that any one should be able to do before even starting an engineering degree.
+Butane Stove the truth is that people who said yes or maybe were kinda right. Generally (as they asked) it is possible. Those who tried also did it right but they didn't show the whole process. And there were none who said it's not possible except the girl who said she needed another wire to close the circuit and she wasn't wrong because generally you use a wire to connect the power source to the load but she didn't realise she can just touch ground pin to negative of the battery.or the other way. I don't feel like electricity is superior and any engineer should know that before starting an engineering degree. But I also find it weird that there are people who seriously can't tell what they need to light a bulb or how to use a battery, it doesn't take an engineering degree to know that...
Leszek Michał I see where you're coming from, but honestly this is such a simple question there is no excuse. If you're an engineer I'd expect you are smart enough to understand the most BASIC fundamentals of electricity. This would probably happen at my university as well. There's a lot of retards who want to be "engineers" but haven't got the slightest inclination for learning. They barely squeeze into graduation because they know how to memorize answers. They lack intuition which is the only thing that matters. This is why even the most stupid individuals can specialize in one thing. I don't assume you're smart just because you graduate college. I've met plumbers who I would consider insanely smart as they have such a wide scope of knowledge and can learn anything very quickly.
I think you don't understand that just because someone failed in the experiment (maybe they were hung over, didn't sleep for days or just panicked because they were put on the spot) doesn't mean they're not smart. They might have expected the question was a trick question and spent their time figuring out where the trick is. If you want to measure intelligence, IQ test is still the best method we have for that today.
+a_slight_veneer_of_privacy I dont see much sense to go into extremes of learning about something. Effort needed to go from that B+ to A is bigger than from B to B+. Its the law of diminishing returns. Meaning that you can with the same amount of effort be capable in a wide variety of fields or be great in just one field. Colleges do make people good in one thing, and that is getting good grades. Those 15% you are talking about are those that genuinely want to grow as a person, not just grow their skill of how to fake their competence.
That's not what they teach in technical schools! They teach theory, equation derivation, mathematical transforms, laws of physics, etc. Practical knowledge? That's not worthy of academic institutions!
Learning physics=learning about electricity. In order to light a bulb you need to have a closed circuit. Theories can be applied to real life for practical uses.
jmichaelrout Well every light bulb except that small one probably required more power to light up than that little battery could possibly deliver. That's why only that one guy barely got that tiny light bulb to light up. Give me a car battery though and you can light up the headlights on a car. Thus it all depends on the battery and the lightbulb that you're talking about.
Geir Sunde No, the question was actually very poorly worded "Can you light a bulb with a battery?" What kind of bulb? A garlic bulb? What do you mean light it? Set it on fire? The question should have been "Can you make this lightbulb turn on with this battery and wire?" Because no matter how you hook it up, a D cell battery isn't going to light up a 20 watt lightbulb, it's barely going to light up a 2 watt indicator light in fact, and even then the battery is going to get very hot very fast from all the current it has to deliver. A flashlight lightbulb? Yes, but they only show one of those in this video, and it's where the guy gets it to light up. All this is is an example of poor journalism.
Justin Hall To be honest I think you're nitpicking. The essence of this was not the initial question, but the following demand for a demonstration where the given battery was sufficient to do the job.
I'm an MIT dropout. I can do it because my dad was an electrician. I could do it before MIT. If someone came to MIT to be an architect, mechanical engineer or geologist they might have been initially stumped by this. If instead of asking the question on graduation day you stuck them in a room and told them make this bulb light they would probably be able to do it after some observation and thinking. It would be interesting to compare the time it took various graduates from different schools and majors.
That would be similar to me (as an electrical engineer) saying I cannot figure out how to change the alternator belt on my car. These dolts need some vocational education.
bighands69 If a mechanical engineer has no idea of how current flows, then that engineer was not paying attention in certain classes. As an electrical engineer, I had to take courses in Newtonian physics, nuclear physics, statics, dynamics, thermodynamics, heat-transfer, mechanics of materials, chemistry, economics, etc. Ditto for mechanical engineers; assuming they are classically trained engineers and not just someone that rose up through the ranks and learned by hands-on.
Didn't you have to take Physics: Electricity, Magnetism, and Optics? I am taking that and there is material about how batteries and resistors work. How the fuck did they pass that class and not know how to hook up a battery to a lightbulb?
They might seem like idiots, but im pretty sure that they could tell you a lot of stuff you wouldnt even understand. Also these clips are probably cherrypicked. *UPDATE:* Since someone in the comments misunderstood me, to clarify: With "stuff" i meant e.g. highly advanced physics and/or math. To understand such things you do indeed need a certain level of intelligence. The premise of this video and title are inherently flawed, as this obviously does not mean they are dumb or unintelligent at all.
+calcyss In today's society, yes there is something wrong with that. An engineer especially needs to be capable of critical thinking. Almost any person in a high up field needs the ability to critically think.
This is filmed at Harvard, not MIT as many others have pointed out in the comments. It is sad how some people intentionally give such misleading clickbait titles.
Hello good sir, did you know that every single person does not remember every single part of every single day they went to school? Some people might forget certain random unnecessary things like where the plus and minus is one a random type of bulb that noone ever uses, you fucking moron ;)
The topic is actually so simple, that everyone should be able to do that. At least everyone who finished a primary school and had a physics course covering basics of electricity. I have no idea how US education system works, but in my country literally every adult (not mentally disabled) person SHOULD be able to do that. Of course it doesn't mean that each person in my country is actually able to do that, but from graduates of MIT I would REALLY expect this skill.
igortcgg there you go, it would be fine if they couldnt hold all the wires but this was just pathetic, shorting the batteries out, only connecting one terminal WHAT THE FUCK AMERICANS
I think I might have the answer. The do not learn this basic shit at MIT. They expect their students to know these things from before, however many people miss out on that one day in school when you get tought this, and many more forget it.
Part of this could be that the students have a good understanding of E&M and can wire circuits just fine, but have never stopped to look at a light bulb. It may not be immediately apparent where the two leads from the battery should make contact with the light bulb in order to turn it on, and then the fact that they are being put on the spot with a camera on them is causing them to be blind to seeing where the leads should go.
mechanical engineer* though every engineering student that takes the basic sophomore level courses have had to learn circuits and probably made basic LEDs at some point.
Golden Duck What can't I figure out? one wire connects to one of the contacts on the battery and one to one of the contacts on the bulb. Then you touch the other side of the battery to the second contact on the bulb. It doesn't matter which way the polarity goes, It's just a resistor. These people were stupid to only connect one side of the battery, but it could never power that bulb anyways.
As someone doing Mech/Electrical Integrated course...the Mechanicals really aren't taught this stuff. One would assume they would know it from Physics A-Level (mandatory where I study) but this isnt always mandatory. Physics GCSE would cover it but boy, thats a long time ago...
well everyone free to own their opinion, theres a reason why university are providing dual programme, mechanical and electrical, even within mechanical theres is electrical & electronic courses. but u my friend, are indeed an ignorant.
the problem is, copying something off a blackboard and then memorizing it to pass a test doesn't teach. it's because doing a lab under a controlled setting with a teacher to help doesn't stimulate your brain the same way as being in the building where you just wired something wrong with a foreman screaming at you why aren't the fucking lights on! you learn incredibly fast and don't forget when you're under the hammer! not being babysat by a university.
I hear that. I was shunned away from the traditional school system. Back 8 years ago when I graduated high school, my mind was finally free and I was able to learn how I wanted to learn. Since then I have literally done thousands and thousands of hours of research on what I wanted to learn. I see it as earning my own personal degree in the life I want to live.
This video is disingenuous, it only makes a fool of the viewer and not the students. Notice that the black student is holding a different bulb than the previous students and listen very carefully to what he says. He was unable to light the first bulb and has just been handed a smaller one that will work with this power supply. It is likely that the clips of the other students are taken after they were unable to light the first bulb with a correct, closed circuit and have reverted to trial and error before giving up. They are hesitant to answer because they know it is a trick question. They are about to be handed a bulb that, like the one in your lamp, will not light with the low voltage a single D cell battery provides.
Actually the video isn't disingenuous - the poster is. It seems the fact that not every bulb will light with every power source is the point they're trying to make but the way it has been cut out of context and posted with this title sets you up to believe they're morons while if you could have seen the big picture you might have a little more sympathy. It's so easy to get views and likes by putting people down, isn't it?
Wander Smut I think you've misunderstood. The students are just not correctly closing the circuit because they've only been given one wire. Every time you see those large domestic bulbs there's a single flex going to it, which could explain why they're just touching the wire to the bulb, hand them a small bulb like that used more commonly in electronic projects and they're more likely to remember that you either need two wires or you need to hold the bulb onto the battery. Incandescent bulbs like that should light up with a battery albeit rather dimly.
Wander Smut ah wait no sorry I've not completely read your comment closely enough. I don't know, I still think the point could be that people forget they have to close the circuit or just realise they don't actually have the necessary practical skills even though they understand what to do theoretically - connect the wire to the bulb. The bulbs should glow dimly when connected properly.
Wander Smut well then he analyzed the materials and figured out the problem and the rest didn't. probably got himself a job somewhere. maybe this was a test a company did to look for someone to hire. some of them didn't get the offer.
Seriously? I mean.. Really? Harvard Engineers? Shorting the poles of battery? I could have done that in 8th grade... Worst kind of engineers they are...
What is basic and fundamental to you is not for someone else, if I say what a bitwise operator is for the one who posted the video she wouldn't know but a computer science person would know it. Similarly people who go to Harvard or MIT are not experts at everything, they are experts at their thing.
Prathik Rajendran M Knowing a concept of _complete circuit_ is a bit more fundamental than bitwise operators. It's like asking an electrical engineer to use ball bearing and axle to assemble a wheel, or architecht to make a sandwich. It's fucking fundamental and simple as shit, not specialization. You can't make a sandwich because you didn't get a cooking degree? Even interior designer should be able to do that.
Pick 4 people that can't do it out of the 20 people you surveyed, put only one that can do it and there you have it, now everyone thinks every MIT student is dumb as a rock because only 1 in 5 can do it. one even stated that she wasn't an electrical engineer, that gives you a hint about how many people they could find that couldn't do it.
The concept is so simple the excuse of not being an electrical engineer is like saying you're not an astrophysicist when you're not able to say which planet is 2nd from the sun. The concept is so simple you should go all day talking to people on campus without finding someone that can't do it...except that one student rolling on ecstasy that tried to suck on the battery. He's the only one that shouldn't be able to do this.
putty93010 no, it is not. It's a simple concept, but it's not a "everybody in the world knows how to do it" thing. Everyone knows the theory, not everyone has done it in the past. You may be talking about the simplest thing ever, but if you ask a bunch of people to do it for the first time, it's more than certain that a small percentage of them will get it wrong on their first try. It doesn't mean that they are dumb, or that they didn't learn anything while studying, or that they don't understand electricity like someone said in the video. They clearly know the basics, they just don't have the "know how" to do it. It's not like the are connecting the wire to the bulb and sticking it on the ground, while leaving the battery out on the sun to 'recharge'. It only shows that they never tried that before, because they never needed to, and probably never will. I'm sure anyone of those who couldn't do that can do a better job in their fields than 90% of their competitors. (and no, i never went to MIT, nor any other school in america btw)
Well I guess the term "dumb" is relative but children can do this (I think I was 7 the first time I did it). And Im'a hafta straight disagree with you. If they can't do this, they don't understand electricity and they are dumb when it comes to electrical concepts and practices.
putty93010 Yeah, and i'm sure you did it on the first try without anyone telling you how to do it too. The rest of us mortals, have to learn how to do something before doing it.
the thing is even mechanical engineers learn electric circuits and physics witch include electromagnetism (god help me with that one)! And more, I think that basic circuit analysis is required like a thing every engineer should know or he don't get engineer title at all! So don't come with the excuse "Oh I'm just a Mechanical Engineer don't ask me nothing about electricity cause I'm not obliged to know" because not correct argument.
+Trafalgar Congrats btw :D I personally think that many of them just have been asked to do that task at the wrong time at the wrong place. It is arrogant to assume that one is more intelligent, just because of one datapoint. In addition everyone can say they knew how to do it, but then again they weren't challenged.
I had a MIT graduate working for me at one point. Very intelligent girl obviously but she had trouble working on our instrumentation (it was a drinking water lab) and it took her an embarrassingly long time to put together a file box with instructions.
Apparently because they can put two wires on a battery better? what exactly are they winning? winner of pollution? rudest tourists in the world? tragedy of the commons? Communism? They can keep on winning
Mr.Tumbleweed the manufacturing and engineering sector. I bought a hartke amp says made in china yet its an American company. Yesterday got a new microwave oven says made in china yet its an American company. I could go on for hours and this coming from a Canadian. That's what china is winning.
rapturekevin Lol, if thats them winning, they can keep on winning. We have plenty more they dont kiddo. Dont delude yourself. Lets be honest. On average who has a happier and more fulfilling life, a chinese or an american? Whose winning?
I spent 7 years as an electrician on the job site before I decided to go to engineering school. I know when I have experience against my classmates when they are much smarter on paper. BTW I did this in 4th grade science class was part of our test
I remember when I was 7 years old I used to light the bulb by using only a battery with no wires at all, by scratching the top of the battery's cover you can access to the negative near the positive end .
This is not a question about electricity. All of them understood that they had to close the circuit in order to light the bulb. They expected two wires and thought the task would be really simple, but instead they were presented with a logic puzzle.
These aren't engineering students. The second semester of physics or the first semester of circuits requires knowledge like this. Hell, in 8.02 (MIT's name for General Physics II), students are asked to build a motor out of a battery and some wire. These people have not done that course.
Well, my brother is a topper PhD from MIT and I'm a bachelor from India, I still correct him on many things so, it doesn't matter where you've studied , it's about how good you are at something.
I have to admit that I had to think for a few seconds to see how to do it with only one wire, since normally you would do it with two wires. Under pressure, with a TV camera in my face, or caught off guard, and all of this at an important event like a graduation where my head would already be swimming, I might not have been able to figure it out.
Okay this is just bad media. I'm willing to bet that the people they asked to create this circuit aren't even studying electrical engineering at all. One of them straight up said she was a mechanical engineer, and then the other guy asked for a tip, now that really doesn't strike me as the kind of guy who was studying electrical engineering. So asking the majority of a crowd that aren't electrical engineers how to create an electrical circuit is not going to get good results. Not just that, the circuit wouldn't work anyway because the battery is DC, and those lights are most likely AC, just like the majority of standard use light bulbs made in America. Even if the battery were AC(which isn't possible), it still doesn't have enough power to light a bulb like that. So asking a non-electrical engineer why that circuit wouldn't work is a complete bias on the entire situation. So good job America's media! You've gone and twisted the story again!
Thank you. Honestly, I thought I was alone here on the point about the media. I don't know, people just seem to have an *extremely* narrow understanding of what intelligence is, and the difference between intelligence and ignorance, intelligence and third party factors (such as having delayed motor functions, like myself), etc. Imo, they promote this way of thinking as it complements the average viewer in a way such that they ill want to tune in to the media station mor frequently, resulting in better ratings. It's just really frustrating arguing with people about this, because the argument is almost always either one-sided or the person I'm arguing with is an enormous hypocrite. Thank god the people I work with in my college aren't like that. :/
William Coburn The bulb used is a very large one. The larger the bulb is the more current it is going to need to be lit. A small 1.5v battery like that simply cannot light a large bulb. And by the way, a resistor is not the primary component within an incandescent light bulb. Nothing within a light bulb even sort of resembles the works of a resistor. Incandescent light bulbs use thin tungsten filaments in a negative pressure bulb, or one filled with a noble gas, such as argon, to promote the dissipation of light. When the current travels through the tungsten, the tungsten burns because it can not support the current passing through it. Resistors do not light up or burn when they come in contact with large currents. They simply dissipate heat. And also, in standard "household appliances", when using an incandescent bulb such as the one shown in this video, no sort of step down transformation or rectification is taking place. The only thing taking place is the burning of the filament from a full 120 VAC power source. And the supposed "small light bulb", is hardly small. From the looks of it the bulb looks to be around 12v. Of course a 12v bulb will not be lit up by a 1.5v battery. It's common sense.
William Coburn I understand where you're coming from, but don't twist my words. You know full and well what I mean when I said resistors don't burn up under large currents. I am referring to a large current in a diminished manor. Also, I never said that lightbulbs did not get hot, so you saying "You even say that the bulb filament 'burns' within the gas-filled vacuum enclosure, which contradicts your early statement since 'burning' implies heat dissipation", is, in a way redundant. And I have never seen a light bulb modeled as a resistor in circuit analysis. In no definition of a resistor that i've ever seen, has it exclaimed that anything that dissipated heat is considered a resistor. It isn't even really about the fundamental understanding of a light bulb. Especially when it seems as though most of the people being interviewed are not engineers of any kind. Sure, you could say that learning to light a bulb with a power source is a basic understanding of electricity, and that they should have learned that in middle school. But tell me, how many of the small things do you really remember in detail from middle school. For instance, if asked you to explain the tectonic structure of an earthquake, or how a mid-oceanic ridge is formed, i'm sure you could not tell me from memory.
3dUber An incandescent light bulb does not care whether it's powered from a AC or DC source. It will light up, but very dimly. Try it yourself at home. Get a piece of wire and hold one end to the bottom contact on a battery, and the other end to the side (screw) portion of the bulb. Then, place the bottom of the bulb on the top contact of the battery. The orientation of the battery doesn't matter. Tell me the results.
this is stuff that children should know how to do. I was taught this in grade 5, we were all given wire, batteries, and bulbs and told to play with them for 15 minutes and see if we could figure it out, then taught how and why it works... The problem is kids/teens/adults don't PLAY anymore
Not necessarily dumber. Just learning completely different stuff, and sometimes too detached from reality and simple things. I believe they could explain things to you that you wouldnt even understand.
calcyss lol true, but this is something they should've learned in high school if not first year right? I mean, I learned this in grade 9 science and grade 12 computer engineering.
***** Well i personally never learnt this (im German), as i slept through it in school lol :D But anyone with a basic understanding of physics should know *why* this doesnt work, or rather why it doesnt work the way they are doing it. Closed circuits are a pretty basic concept.
The very first thing that came to mind was "how much voltage does the battery provide, how much voltage does the lightbulb require, and how much resistance does the wire have?" Of course it's possible to do it, but only IF the battery can supply enough to overcome the resistance of the wire and the lightbulb.
If the interviewer actually had shown in the video how to light a bulb with the battery he gave them, the video would have been correct. Is that supposed to be journalism?
Pablo Blo wait what? no you misunderstand, the interviewer wasnt teaching them how to light a bulb. which is something taught to 6 year old children in the UK and demonstrates a basic fundamental understanding of the manipulation of electricity. They simply provide the means to light the bulb and ask a bunch of graduates from the most prestigious technical college in the US if they can light a bulb using skills they should already have.
Pablo Blo I disagree. An engineer should know that a 110 AC bulb won't work on a 9 or less Volt battery. Noone asked what type of a bulb is it (one could dissassemble a 110V LED bulb and make individual LEDs light up with a normal battery), noone asked what type of battery, the idiot on 1:39 shorted out the battery, one student assumed they failed when it didn't work without even asking can it work. Those are not engineers, those are kids with engineering diplomas and a disgrace to acctual engineers. I understand that to people that aren't engineers this seems harsh but remember: engineers design the stuff you buy, and one of them is now an idiot that tried to power something with a battery by shorting the battery out. Source: i'm an engineer (a mechanical engineer to make it even more ironic)
+Fleksimir I think you're being too harsh, based on a cherry-picked video with nervous people being asked to do something new on camera. We all have that part of the course that we hate and just dish out on the exam and forget, only to realize later that we need it. Their skill on this particular practical problem this one time can't really be extrapolated to their skill on everything else.
+Pedro S You are not wrong and you definitely have a point. Infact i would say the same thing for lots of other things students don't know to do. I think i just consider this to be too basic to fail.
They teach this in 8th grade science and I thought it was one of the more fun things in that class but they only spent like 2 days on it cuz it is so easy. Now I'm in 10th grade and I took digital electronics as a math credit and just a few days ago the teacher gave us a computer program to model circuits and I finished early so I made a simple binary calculator for fun.
oh my gosh! People don't go to school to learn, we go to get a piece of paper that employers recognize and will then hire us. Otherwise businesses would hire all those crazy asses from Russia
Hybodus Shark Ok, so if you're so open minded, try convincing the employer you're up to the job without a degree. Smart people still need official recognition or nobody would hire them. It's only a scam for dumb idiots but for smart people, uni is worth it.
Andrew Wei What employer? If they judge ones status based on a so called 'degree' then there not worth my time now are they? Plenty of other jobs out there depending on where you look and how you live and spend your money and so forth.. yep Definetly worth busting ur ass in uni for a worthless piece of paper.. Enjoy wasting your time in college bud.. Very well worth it for you..
I never saw anyone explicitly state that they are MIT graduates in the video, and I think that the uploader got rejected when they applied and is lashing out.
***** When I was in elementary school my parents worked for a hard drive repair company, and whenever there was a bad drive that already had the data recovered from it they would let me take it apart, and take out the magnets. I ended up putting two of them together on my ear and had a hell of a time trying to take it off... at least I was in style :P
So according to Prof Sadler, if a person cannot complete a correct circuit with a battery and wire to light up a bulb, then "EVERYTHING ELSE HAS PROBLEMS" Really? That's how you test intelligence, knowledge, wisdom and creativity?? Well you know what you can do with your little electric circuit test? What a ridiculous demonstration at a graduation ceremony.
Peter Kan Yes Peter, that's how the world test intelligence. If you use something as a fact or have hypothesis to create something. if that fact or hypothesis is already wrong then how do you expect the final result to be correct. We have learnt that nothing can travel faster than the speed of light(theory of special relativity) but now scieentist have discovered neutrino's which can travel more faster than light. We use special relativity as a fact but now its proven wrong which means everything related to special relativity or use special relativity is wrong. Why do you think it's ridiculous? Just because it shows the truth. I think graduation ceremony was the best place to demonstrate this,
+Rachel Matthew "Scieentist" have NOT discovered "neutrino's" that can travel "more faster" than light. Better work on your neutrino knowledge, along with your English spelling and grammar.
+Rachel Matthew actually that particular measurement concerning neutrino speeds has be debunked and sorted out. You need to keep up with the latest developments and follow things through right til the end. You should apologise to everyone on the internet, withdraw your remarks and ban yourself from using TH-cam for 48 hours
+Peter Kan man just don't talk about neutrino specifically. You get what I wanted to say. Now that you don't have a point you are just pointing silly mistakes which I just used to convey my point. Do you even know how to debate? Ban yourself from TH-cam. so dumb comment like what were you even thinking. Just ban urself frm Internet.
EDIT: Literally two seconds later in the video they showed what I talk about below. I didn't watch that far in before writing this stuff, though it's good to get a confirmation that it was correct. I'm not sure which goes where on the bulb, of the - and +, but I know one part has to go in from the bottom and the other from the side of the socket on the bulb. Put the bottom part of the bulb on to the corresponding part of the battery then take the wire and have it touch the side of the socket on the bulb on one end then the other end of the wire to the opposite side of the battery from where the bulb is touching. Voila. If I get the - and + wrong the first time I'd simply reverse and surely get it right the second time.
Since when do u need an electrical engineering degree to fkin light a bulb ? This is some shit all of us should have learned by the age of 8-11 I was fkin breaking atari game consoles and taking out the PCB and playing with it when i was 10..... it's basic knowledge people
The really scary part is how confident these students are in their own abilities. These students have played the game, and short-changed themselves of an education. Understanding isn't a requirement for success.
The big 120 volts light bulb sure lights up on the 1.5 volts battery but we don't see the light because it's too weak for our sight, but, if you observe the light bulb through a cellphone camera which is infrared sensitive then you will see it lights up because the filament gets a little bit warmer and irradiates infrared radiation.
First off the size of a bulb is not necessarily directly proportional to it's voltage requirements. There are small bulbs that are 120v (usually in a night light) and there are very large bulbs that are 2.5v. It was clear (at least to me) that they weren't trying to trick anyone. Second, a MIT graduate should be able to read. The voltage rating is printed on both the bulb and battery so if the battery couldn't illuminate the bulb, them even attempting is quite humorous. And finally unless your phone camera lens is bigger than your dilated pupil, it cannot detect wavelengths bigger than what your eye can see (infrared). Most infrared cameras have a lens diameter of about 5 inches. I'm guessing you meant electromagnetic radiation in the infrared spectrum, there's no such thing as "infrared radiation"
putty93010 First; I know that the size of a bulb light has nothing to do with voltage. I just wanted to be descriptive. Second; Being graduated at MIT is not a guarantee of basic and practical knowledge at all. School does not make students. Third; The size of a lens has nothing to do with detecting bigger or shorter electromagnetic wavelengths. Most of cellphone cameras are able to detect infrared radiation. Infrared wavelength is even shorter than microwave radiation so it can easily pass through the tiny lens of any cellphone camera. ¿Why don't you do that experiment at home? Greets.
Break the wire into 2 separate pieces & connect them individually to +ve & -ve terminal. Then connect the other 2 to bulb & it'll light up. (3rd grader)
You don't even have to do that. Connect one end of your wire to one terminal of the battery and the corresponding terminal in the light(bottom or side of bulb) and connect the opposite battery terminal to the other end of the bulb and voila, you will have light. Given that you have enough current for the given light bulb.
Wasif Ali That is what exactly I was thinking. I thought at the start of the video that the journalists were fooling the graduates. When I was watching the video I said to myself "Cut the wire into 2 pieces" and light it up. Basic electricity concepts. I don´t know what kind of bulb the journalist had, but I am sure the battery is a 9V one.
MChiribogaD Pardon me but USA high school system i.e GED/Diploma has so many flaws regarding adequate academics skills given to students before going to university as compare to those in UK (Gce & Gcse's) which I've studied. Not being ostentatious but for us, this is a breeze.
Wasif Ali I think the US education has some flaws considering the fact that the US is considered a developed nation. Countries located in Europe actually give more advanced programs that they do give in the US. Even countries in Hispanic America give more advanced programs than in the US. I have a friend that was applying for the UK and she was not admitted for getting into an university because the US curriculum from her school didn´t covered the programs that the UK high school system covered, thus, she applied for a foundation year. USA considers Calculus as AP,while in other countries is just part of the common curriculum. I am from Ecuador, and when I moved to Santo Domingo, DR, I went to an US school ( I don´t like to refer "American" just for the US but rather for the whole continent) and when they started giving Chemistry it was literally everything I saw last year in my last year in Ecuador, Math the same, and Physics...no physics bro! In senior year we just had physics, and guess what...the majority of topics I already covered them in Ecuador during 10th grade while in the US education they give them in 12th grade. In 11th grade I didn´t had physics. I was so sad, because physics is my favorite subject, so I decided to self-study physics with my physics book from Ecuador (Física "Paul E. Tippens") So that´s what I think. Best regards.
To all the people defending these students... most of them weren't hooking the wire up to each end of the battery. It doesn't matter how big the lightbulb is or what the quality of the wire is; if they don't know the basics to making a running current, then they're stupid.
Austin Fisher The experiment was designed not to work. Just so you know, a 1.5V D cell battery can't light up a 60 watt light bulb, which is designed to work on 120V AC. The only fault with the students is that they couldn't explain why the bulb couldn't work, but the reporters completely misrepresent the situation to make them look like dumbasses. An example of this is the fact that they used a bulky D cell battery to make it look adequate enough to light the bulb, when in fact it has the same voltage as a small AA battery. Look at 2:00. It only worked for him because they used a smaller bulb. And even then, look how little it's lighting up! You can't possibly expect to produce the same, let alone greater, results with the bigger bulb.
FunOrange Bro it's not about whether the bulb was lit up or not. It was they approached and answered the question. Sometimes if you learn too many complex things, you forget all about basics. None of them had a good approach, confidence and a fair answer. They literally had to think for a minute to answer the question which is very wrong as an engineer. This is the point where one person gets the job in the interview and another doesn't. The way you answer, your confidence, each and everything matters. Each and everyone was thinking like it was very hard math problem and after all thinking they were like ya they can do it.
this was about electric principles, I learn and make it on school, but must required certain conditions, the battery power, the power requirement of the bulb and the conductivity capacity of wire.
+Otto Rivera Yup! And I'm only 19 years old ... hell I fix electronics things as well, and I haven't gone to college. Just goes to show, that with the right mind/thinking style, anyone can easily do anything.
I interpreted the video as saying we build knowledge on a foundation that we were never taught to have. I, for one, have never been explicably taught many things that are supposed to be self-evident, but had to learn backwards in a way by doing higher level work. Of course they know how batteries and electricity works, but especially at that level, they are expected to know basic things, but are never taught those things out of need to cover bigger picture topics. I am thankful to be grounded with people who aren't as higher level as I've been taught and I learn just as much from them about the world that I never could have learned in my classes.
my brother asked me the question the other day, I scratched my chin for five seconds and told him I could put one end of the battery to bulb's contact. I only found this video afterwards.

The woman who said the current couldn't flow without a complete circuit was technically correct... she simply didn't know that that base of the bulb could be used as a connection. Simply a misunderstanding of the properties of the bulb as opposed to electrical current theory. This is a prime example of education vs experience in the field.
I don't think it's failure to understand the properties or construction of the bulb at all. I suspect that had she been given a 2nd wire she would have immediately connected it to the light bulb and battery correctly (as would several of the others). The problem here is not failure to understand how the most basic electrical circuit works, but failure to adapt when a simple problem is presented in a non-standard way. People just do not visualize a light bulb (or motor or almost anything else) in direct contact with its power source.
I do think this non-adaptability (related to poor critical thinking) is a real problem, but the video misrepresents it.
Blake Marshall When you connect the end of the bulb you basically complete the circuit.
And I think she was an Indian. And there was another genius who was a Black person if you will.
"In their classic paper Perception in Chess, Chase and Simon reported on a study that compared the abilities of experts and novices to remember the positions of pieces in chess. *When pieces were arranged on the board as they might be during a game*, the experts' memories were far superior to the novices'. When the pieces were arranged randomly, there was little difference between the memories of the experts and the novices. The traditional interpretation of this result is that an expert's memory is not inherently better than a novice's but that the expert has a knowledge structure that helps him or her remember particular kinds of information. When new information corresponds to the knowledge structure -- in this case, the sensible placement of chess pieces -- the expert can remember it easily. When new information doesn't correspond to a knowledge structure -- the chess pieces are randomly positioned -- the expert can't remember it any better than the novice.
A few years later, Ben Shneiderman duplicated Chase and Simon's results in the computer-programming arena and reported his results in a paper called Exploratory Experiments in Programmer Behavior. Shneiderman found that when program statements were arranged in a sensible order, experts were able to remember them better than novices. *When statements were shuffled, the experts' superiority was reduced.* Shneiderman's results have been confirmed in other studies. The basic concept has also been confirmed in the games Go and bridge and in electronics, music, and physics." src. CodingHorrors

Holy fuck dude. I do not think you understand the simplicity of the task they were told to do. There is no excuse except for the editing.
It's a fucking light bulb not a nuclear reactor.
I like how the only guy that did get it correct was the guy who answered "maybe", instead of giving in to the pressure of saying yes outright.
Yes, as indicated from 1:46 onward, what he recognised was that he needed more information about the battery and the bulb to answer Yes or No to the question. The video cheats by not showing people wiring the circuit correctly but still inevitably failing to light the 120v bulb with the 1.5v battery- except the cheat is, as most of the comments sadly illustrate, part of the education. If people don't consider all aspects of the situation (including, in this case, the fact that only the "maybe" guy was shown succeeding with a bulb of more suitable voltage rating) they will get the answers wrong.
No, the question was whether they could light a light-bulb with a battery and a wire. It doesn't matter that they weren't able to light that light-bulb with that battery and that wire.
It absolutely does matter, because the full correct answer to the question would be something like:
"Yes, IF the battery provides a suitable voltage to make the bulb glow in the visible spectrum, AND the wire is long enough to connect the further terminal of the battery to the bulb, AND the bulb is a working light-bulb, as opposed to, for example, a tulip bulb".
No the general statement contains all the subset possibilities. Proving that birds can fly does not entail proving that every bird can fly. Proving that two or more birds can fly would prove the statement, that birds can fly.
If you try to expand the many influences that you are talking about, then you can go further into if the wire is too resistant to current, if the wire is conductive at all, if the surroundings can transmit electromagnetic waves, if you are talking about the moment in which the circuit is connected since inductance can prevent the current from immediately appearing, if the questioned does not have a seizure while attempting to do so.
Being able to light a light-bulb in any situation proves the statement of yes to the question, "do you think you could light a bulb with a battery and wire?" One instance in which they cannot, does not disprove the possibility that they can. If that were the case, then all laws of physics would be "disproven."
If anybody is wrong, the creators of this video are in the wrong for not displaying the correct way to light the light-bulb with that set of equipment, if there even was a way. By your logic, I could ask them the question, then immediately shoot them on the spot. Therefore their statement would be wrong because they couldn't prove it using the equipment I was about to provide them.
Also, it is the question that needs fixing. "Do you think you could light a bulb with a battery and wire?" Should be "Do you think you could light THIS bulb with THIS battery and THIS wire?"
Without specifying, the statement defaults to the general, and you just become an idiot that is trying to make graduates look like idiots with your flawed logic. If you tried to do this as a test for something like the SAT/GMAT/whatever, you would get sued and lose your job.
How many MIT graduates does it take to power a lightbulb?
LOL :P
oh no🤦♂️😆
The guy who said, "maybe" paid the most attention in class. All of my engineering professors (sadly, I'm not an MIT alum) told us the answer to ANY engineering question is almost always, "it depends."
Same with the law
Excellent. In most contemporary problems there are A LOT of variables.
Or you say "I don't know" and then try it
Q1. Are you an idiot
*Maybe*
And notice he is the one who got it to light up
How to create a video like this one:
Ask person after person to try to complete a task, knowing that some proportion will fail. Stop when you have recorded as much footage of failure as you need. Omit successes when you edit your video so that the failures seem more frequent than they are. Release the video and see how much it provokes its audience.
C Doyle The idea is that the task being asked requires much less intelligence than MIT graduates are given credit for. Anyone that has passed basic high school physics should be able to light a damn bulb.
They showed some of them succeeding but who cares about what they actually did, YOU FEEL WRONGED EVEN THOUGH THERE'S NO EVIDENCE OF IT! THE OUTRAGE!!!! HOW COULD THEY!?!?
C Doyle So true, Veritasium is a pioneer in this!
Dude, have you any idea what you need to score in high school sciences and maths to be considered for MIT? I don't think there is a single student in my grade 12 physics class in my town that couldn't do it. Then you have some dumbass saying she was a mechanical engineer and not a electrical one? Holy shit!! And she'll have employers lining up with signing bonuses to hire her.
An "engineer", no matter from which university from which country, who can't light up a bulb with a wire and a battery, is too much of disgrace for that student and for that university and he hasn't deserved his graduate. It's just like as if a math graduate wouldn't be able to prove the pythagoras formula of a²+b²=c², because both are stuff, that you learn at school and which are basic for that study.

1) Question is misleading. If it was the right bulb, they could have done it. Battery is too weak for this kind of bulb
2) We only saw students who have failed. What about them who gave the right explanation why is it not working ?
3) Typical TH-cam video. Only clicks, shares and comments matters.
yessssss someone understands something
sure, only the students who failed are exposed. but only if 2 or 3 fail it is still tremendously disappointing
Yes. Because it shows that they give diplomas to people who cannot light a light bulb.
+Bon Bon Why do all MIT graduates need to construct the circuit that lights a bulb without instructions? I think the large majority of people maybe 80%+, have never had to work with bare wire without instructions. And if they did, the MIT grads could quickly learn how to do it.
timithy4569 Because MIT stands for Massachusetts Institute of *Technology* :P
They don't need to deal with bare wire all the time, but they at least should know how to deal with it when they face such problems. (And they _will_ face!) If you only learn how to play with toys made by other people smarter than you, then you're not really that smart. One day there might be no smart people and their toys around and what then? You would have to be smart enough to build such toys yourself in order to do something more high-level next. Or your fancy toy may break and you will have to fix it. That's what engineers do, isn't it? :q
I want to know how none of them called out the fact that its a 120 volt AC bulb and a 1.5 volt DC battery. Did no one really get that?
Valid point...
Hailstorm i would say you dont know basics.. Transformer cant be made with dc..
he said a boost converter, those dont work with AC, you just need some caps and an IC
007K an AC lightbulb? they don't exist, either a lightbulb or an LED. An incandescent lightbulb works with both AC and DC circuits, a diode works only with properly configured DC circuits. Also the bulb looks an awful lot like a lightbulb from a cheap bike light or an internal light in a car. in which case it would be 12v, and 1.5v would be more than enough to light it.
autoformer?
Lets ask this question to our presidential candidates.
hahahaha xD
Exactly! I always wondered why don't ,we as people, ask every candidate should be an engineer as a requirement? May be the world would focus on real issues rather than the politics we are blinded with currently.
Too late. Too late.
Keep asking the question to yourself.
No, because not every person in the world is an engineer. Let's ask you about the strategical impact of the Northern European plain in both world wars, how about that ?
I've been a mechanical engineer working in silicon valley for over 25 years. I never understood why they can't teach these kids basic things instead of putting emphasis on calculus and thermo etc. which I have never used my whole career! Most of what they pay you for in the industry is to solve problems that no answer exists yet. You find the answer and tell the world what you find. Its' called Innovation. The engineering curriculum needs some serious updating as it is the same as is was in my time in the 80's! Teach them how to put things together, and produce designs that can be manufactured. There's wayyy too much theory and not enough real world working knowledge. Most of the new grads feel great about themselves at first with all their knowledge they picked up in college only to slowly discover over the years that you use very little if any of it.
Because most advanced research abstracts away fundamental knowledge
Just because you personally never use calculus or thermo does not mean it shouldn't be taught.
they just went through 4 years of hell, anxiety and exams. don't give them another test on the spot at the day of their graduation xD.
Thats not how the REAL World works, Bruh.

How often do you think about fathers raping kids? Thats quite disturbing.
Dragorific they were at MIT in Massachusetts, not a foxhole in Afghanistan. tell me more about this hell they were in.
Colter Hikel True that xD
And how many did they interview that did manage to light the bulb?
Yeah I know, these are probably like the 4 people out of the whole graduating class that got it wrong.
If they are engineers they obviously will be able to do it. But if they are computer science or finance then they will more than likely not know how to.
Frankly, this is the type of thing you should be able to do in 3rd grade. They don't need their degrees to buy groceries or do the dishes and they certainly don't need their degrees to complete an electrical circuit. This is not about the degree, it's about the foundation that the degree is built on.
Sure, there are lots of things we should consider 'basic knowledge' that you should get from a modern education, but it really is unreasonable to expect everything to sink in for everyone - if you look hard enough there will be people that don't know pretty basic facts. We can bemoan the fact that the education system is horrible, wasn't it so much better in the old days, you don't learn anything at university ... etc etc, but really it's not true: society hasn't collapsed into a bunch of idiots, we are going foward faster and faster and things are way way better than they were in the 'old days'. It's just silly to expect every single person to know how to make a simple electric circuit, even MIT graduates. Some people don't know how to cook food, some people don't tie their shoes properly - well ok, but overall things are fine. If they were electrical graduates, I'd be more worried - but the people that say 'you don't learn anything at university' have completely missed the point of university (or they were terrible students, or a terrible university)
Um, with that larger bulb: none. A single D-cell battery is not enough power to light that bulb. Pretty sure that was the point.

DOUGLAS SCOTT Actually the light bulb problem has no tricks at all. It's simply assessing their understanding of a basic closed circuit. To discover their are MIT grads unable to solve this basic problem implies the teaching is fundamentally ineffective.
Arif K
How many volts is a standard Candle Bulb?
How many volts can a D-cell battery output?
Please link to us a 1.5v Candle Bulb of the same size in this video from any manufacturer.
The only person who lit up a bulb, used a tiny DC compliant torch bulb, guess what it was designed to run on?
My point still stands, you just do not understand both Physics and sarcasm.
They are not stupid because they could not light up the >=20W light bulb. They are stupid because most of them could not even close the circuit. And they didn't understand why it would not light up even if they would have closed the circuit. Thats two basic things they should have known. I knew this when I was 8 or 9 . The guy that was shown with a small bulb was the one that said "maybe", because he understood that he needed more information about the battery and bulb.
Lmao, Hakon is right, half the kids don't even put the wire to both ends. Its like they really just dont understand how a battery works. Oh but no a rich Ivy league school could never have dumb ass kids with rich parents. Its just cherry picking, yes :^)
It's in no way related to what they are worth. Harvard Professor's saying that '...everything else that's built on it is questionable' is disappointing. It's like for Bill Gates to be Bill Gates, he needs to be able to fix my neighbor's crappy laptop.
Which he probably could, in fairness.
What Bill Gates did was to get lucky and then act like a stupid rock star.
You are missing the point about Bill Gates. He is not as brilliant as his wealth would suggest. He is a leading philanthropist because of a fortunate combination of circumstances and not necesarily because he is a great person.
Bill Gates did not invent a technology. His company wrote an operating system (software) and made a deal with IBM to use it on their PC's. Given the computer-craze that kicked shortly there-after, it was a bit like having a patent on air.
Not to say that Microsoft did not in some way contribute to the computer market, but it was more IBM that invented technology.
Mike Betts I think you could argue that software is a technology. But your general point stands.
Electricity/electronics is one of those things with a tremendous chasm between "book learning" and "practical experience." To answer even the simplest questions about what will happen if certain components are connected, etc., (much like the question in the video), you are MUCH better off if you have "played around" with lots of circuits and building and modifying common functional circuits. Even lab classes don't really help. You have to spend time, on your own, really working through the practical realities...
Yup, my train of thought as well. I was less surprised at their inability to figure it out and more amazed that they gave some bullshit excuses or even said they could in the beginning. Instead of thinking to themselves, well, can I do this?
Nah, these days everything is modular so if you focus on your circuit it is simple. Systems engineers will focus on everything working together as long as you take the necessary design decisions.
I think they were just more caught off guard. Expecting to be interviewed about how it feels to graduate from the most prestigious uni in the world, but to see they are being asked a simple question in a degrading way. I doubt they are stupid. That is a fallacy. This is more insight into human psychology.
Ding ding ding, that's why intense electronics courses all have difficult, long lab sessions.
As electrical engineer I can say that this kind of question is completly wrong and misleading. What is a light bulb and what's a battery? Neither of these say anything about the power supply and the load except that we have DC power supply and that the load suppose to lit. This question cannot be answered correctly except: I don't have enough data to judge. But it also says something about them as young engineers, they don't have that habit to look for needed data, to solve issues from the very beginning. They just blindly say yes or no without having proper data to answer. Another thing is that asking mechanical engineer about electricity is not a good idea. There's a reason why people get specialized education. That's because no one can be great at everything or even lots of stuff. Not enough life, not enough time. But one can be great at one discipline. But we got to the point where people have good knowledge about one discipline but they don't know the first thing about anything else. And people with varied knowledge are really needed right now. I don't know about MIT but when I was getting education at my uni of tech, 90% of the program was pure theory. Now looking at it after a few years, you are not engineer because you got a degree. Engineer is a diploma + a few years of experience in your discipline. Then you can call yourself an engineer. I have a few friends that have the very same diploma as I do but they wouldn't be able to do anything practical, all they can do is sitting in front of computers.
yo... my dude. they didn't just ask the question... they gave them the battery and the bulb and the wire. And they couldn't figure out how to do it. It's something that any one should be able to do before even starting an engineering degree.
I was thinking exactly this , depending on the power of the bulb it might not light at all due to the power and voltage of the battery.
+Butane Stove the truth is that people who said yes or maybe were kinda right. Generally (as they asked) it is possible. Those who tried also did it right but they didn't show the whole process. And there were none who said it's not possible except the girl who said she needed another wire to close the circuit and she wasn't wrong because generally you use a wire to connect the power source to the load but she didn't realise she can just touch ground pin to negative of the battery.or the other way. I don't feel like electricity is superior and any engineer should know that before starting an engineering degree. But I also find it weird that there are people who seriously can't tell what they need to light a bulb or how to use a battery, it doesn't take an engineering degree to know that...
Leszek Michał I see where you're coming from, but honestly this is such a simple question there is no excuse. If you're an engineer I'd expect you are smart enough to understand the most BASIC fundamentals of electricity. This would probably happen at my university as well. There's a lot of retards who want to be "engineers" but haven't got the slightest inclination for learning. They barely squeeze into graduation because they know how to memorize answers. They lack intuition which is the only thing that matters.
This is why even the most stupid individuals can specialize in one thing. I don't assume you're smart just because you graduate college. I've met plumbers who I would consider insanely smart as they have such a wide scope of knowledge and can learn anything very quickly.
I think you don't understand that just because someone failed in the experiment (maybe they were hung over, didn't sleep for days or just panicked because they were put on the spot) doesn't mean they're not smart. They might have expected the question was a trick question and spent their time figuring out where the trick is. If you want to measure intelligence, IQ test is still the best method we have for that today.
uhhh most of the people were Harvard students not MIT.
Did these people never play with batteries and bulbs when they were kids?
U Wot M8 seems like they didn't
+a_slight_veneer_of_privacy I dont see much sense to go into extremes of learning about something. Effort needed to go from that B+ to A is bigger than from B to B+. Its the law of diminishing returns. Meaning that you can with the same amount of effort be capable in a wide variety of fields or be great in just one field. Colleges do make people good in one thing, and that is getting good grades. Those 15% you are talking about are those that genuinely want to grow as a person, not just grow their skill of how to fake their competence.
That's not what they teach in technical schools! They teach theory, equation derivation, mathematical transforms, laws of physics, etc. Practical knowledge? That's not worthy of academic institutions!
Why not have both?
practical knowledge can be learned outside of school, unlike theoretical knowledge. That is not my thought, but the one behind my school's teachings.
Learning physics=learning about electricity. In order to light a bulb you need to have a closed circuit. Theories can be applied to real life for practical uses.
They have labs, you can't be an engineering without going to labs. Labs carry around 30% of the marks!!
MrOmnos labs have for main purpose to demonstrate the veracity of a theory, not to teach you how to plug a light bulb.
It was a trick question. The correct answer would have been "It depends on the battery and the light bulb."
Justin Hall Explain.
jmichaelrout Well every light bulb except that small one probably required more power to light up than that little battery could possibly deliver. That's why only that one guy barely got that tiny light bulb to light up. Give me a car battery though and you can light up the headlights on a car.
Thus it all depends on the battery and the lightbulb that you're talking about.
Justin Hall The question wasn't "can you power any light bulb with any battery?", so I fail to see the relevance here.
Geir Sunde No, the question was actually very poorly worded "Can you light a bulb with a battery?" What kind of bulb? A garlic bulb? What do you mean light it? Set it on fire?
The question should have been "Can you make this lightbulb turn on with this battery and wire?" Because no matter how you hook it up, a D cell battery isn't going to light up a 20 watt lightbulb, it's barely going to light up a 2 watt indicator light in fact, and even then the battery is going to get very hot very fast from all the current it has to deliver. A flashlight lightbulb? Yes, but they only show one of those in this video, and it's where the guy gets it to light up.
All this is is an example of poor journalism.
Justin Hall To be honest I think you're nitpicking. The essence of this was not the initial question, but the following demand for a demonstration where the given battery was sufficient to do the job.
I'm an MIT dropout. I can do it because my dad was an electrician. I could do it before MIT. If someone came to MIT to be an architect, mechanical engineer or geologist they might have been initially stumped by this. If instead of asking the question on graduation day you stuck them in a room and told them make this bulb light they would probably be able to do it after some observation and thinking. It would be interesting to compare the time it took various graduates from different schools and majors.
Is your father engineer or electrician?
Architects need to build electrified buildings. Mechanical engineers have an electric motor somewhere. A geologist...use flashlights.
Agreed. Most of them were not (must have not been) electrical engineering graduates.
Socialist? Why bro?
I'm glad you're attempting to justify flunking out
"I'm not an electrical engineer, I'm a mechanical engineer." What?
DickButt I like your profile picture
That would be similar to me (as an electrical engineer) saying I cannot figure out how to change the alternator belt on my car. These dolts need some vocational education.
Mechanical engineers have no clue as to how current flows. How would we expect them to.
bighands69 If a mechanical engineer has no idea of how current flows, then that engineer was not paying attention in certain classes.
As an electrical engineer, I had to take courses in Newtonian physics, nuclear physics, statics, dynamics, thermodynamics, heat-transfer, mechanics of materials, chemistry, economics, etc. Ditto for mechanical engineers; assuming they are classically trained engineers and not just someone that rose up through the ranks and learned by hands-on.
Didn't you have to take Physics: Electricity, Magnetism, and Optics? I am taking that and there is material about how batteries and resistors work. How the fuck did they pass that class and not know how to hook up a battery to a lightbulb?

Lmao, i thought i am the only one who can see these mfs
They might seem like idiots, but im pretty sure that they could tell you a lot of stuff
you wouldnt even understand. Also these clips are probably cherrypicked.
*UPDATE:*
Since someone in the comments misunderstood me, to clarify: With "stuff" i meant e.g. highly advanced physics and/or math. To understand such things you do indeed need a certain level of intelligence.
The premise of this video and title are inherently flawed, as this obviously does not mean they are dumb or unintelligent at all.
But yes, its a bit funny they dont quite understand why the bulb wont light up properly/at all, lol
And many of those things are simply crammed, muscle memory information that they can spew. Completely different from critical thinking.
catindabox 334 Yes, thats not entirely wrong either.
+calcyss In today's society, yes there is something wrong with that. An engineer especially needs to be capable of critical thinking. Almost any person in a high up field needs the ability to critically think.
Yes, regular guy working at car repair or somethin are smarter. Too bad they don't go to school if its so easy and earn 5x as much.

Hello good sir, did you know that every single person does not remember every single part of every single day they went to school? Some people might forget certain random unnecessary things like where the plus and minus is one a random type of bulb that noone ever uses, you fucking moron ;)
Aski Found the MIT grad.
Aski I remember that from 3rd grade
Well that's unfair.. those kids were severely hung over.
butt, but i was doing this since i was five wtf man
But some people have never done this very specific activity, which means that not everyone knows how to do it.
but still COME ON
The topic is actually so simple, that everyone should be able to do that. At least everyone who finished a primary school and had a physics course covering basics of electricity. I have no idea how US education system works, but in my country literally every adult (not mentally disabled) person SHOULD be able to do that. Of course it doesn't mean that each person in my country is actually able to do that, but from graduates of MIT I would REALLY expect this skill.
igortcgg there you go, it would be fine if they couldnt hold all the wires but this was just pathetic, shorting the batteries out, only connecting one terminal WHAT THE FUCK AMERICANS
I think I might have the answer. The do not learn this basic shit at MIT. They expect their students to know these things from before, however many people miss out on that one day in school when you get tought this, and many more forget it.
Electrical engineer master race here.

Keystone Science Stop talking to yourself
Part of this could be that the students have a good understanding of E&M and can wire circuits just fine, but have never stopped to look at a light bulb. It may not be immediately apparent where the two leads from the battery should make contact with the light bulb in order to turn it on, and then the fact that they are being put on the spot with a camera on them is causing them to be blind to seeing where the leads should go.
Obviously it's a load of bollocks. However, I will insert my joke:
Even Harvard have art history students.
she literally said she is an engineer
mechanical engineer* though every engineering student that takes the basic sophomore level courses have had to learn circuits and probably made basic LEDs at some point.
Well she couldn't have literally said she was an English major, because then she would literally know what the word "literally" means.
Joshua Mcateer *has
Gender studies is a real course at HARVARD
You're expecting a D battery to power a 60 watt lightbulb?
*Edit; Read the rest of the thread before you call me an idiot.
You can't figure it out either, huh?
Golden Duck What can't I figure out? one wire connects to one of the contacts on the battery and one to one of the contacts on the bulb. Then you touch the other side of the battery to the second contact on the bulb. It doesn't matter which way the polarity goes, It's just a resistor. These people were stupid to only connect one side of the battery, but it could never power that bulb anyways.
The Captain Depends on what it means to say "power that bulb".
erik shure I mean heat the metal enough to start producing light.
did you even watch it? 1 guy lit it up...
"I'm not An electrical engineer. I'm a mechanical engineer. It's probably operator error" wtf??
ToothyGus what about it? She admits she doesn't know what she's doing hence why she says that it's operator error.
As someone doing Mech/Electrical Integrated course...the Mechanicals really aren't taught this stuff. One would assume they would know it from Physics A-Level (mandatory where I study) but this isnt always mandatory. Physics GCSE would cover it but boy, thats a long time ago...
ToothyGus mechanical engineering can not stand on its own in todays world, unless its a steampunk era.
Shahrizal Ibrahim you're a moron
well everyone free to own their opinion, theres a reason why university are providing dual programme, mechanical and electrical, even within mechanical theres is electrical & electronic courses. but u my friend, are indeed an ignorant.
the problem is, copying something off a blackboard and then memorizing it to pass a test doesn't teach. it's because doing a lab under a controlled setting with a teacher to help doesn't stimulate your brain the same way as being in the building where you just wired something wrong with a foreman screaming at you why aren't the fucking lights on! you learn incredibly fast and don't forget when you're under the hammer! not being babysat by a university.
redlinerer in fairness to unit and especially MIT, it's an incredibly stressful place
Spoken like someone who hasn't studied engineering at a university. Babysitting is the last term I would use to describe that experience.
I think I was like 6 years old when I took apart a flashlight and figured out the connections. And I had D's and F's in high school. WTF
There's a difference between your actual intelligence and a number on a piece of paper.
I hear that. I was shunned away from the traditional school system. Back 8 years ago when I graduated high school, my mind was finally free and I was able to learn how I wanted to learn. Since then I have literally done thousands and thousands of hours of research on what I wanted to learn. I see it as earning my own personal degree in the life I want to live.
James Over Yonder none of this means anything
How many MIT graduates would it take to screw in a light bulb?
erik shure 0 none of them will know how to do it.
This video is disingenuous, it only makes a fool of the viewer and not the students. Notice that the black student is holding a different bulb than the previous students and listen very carefully to what he says. He was unable to light the first bulb and has just been handed a smaller one that will work with this power supply. It is likely that the clips of the other students are taken after they were unable to light the first bulb with a correct, closed circuit and have reverted to trial and error before giving up. They are hesitant to answer because they know it is a trick question. They are about to be handed a bulb that, like the one in your lamp, will not light with the low voltage a single D cell battery provides.
Actually the video isn't disingenuous - the poster is. It seems the fact that not every bulb will light with every power source is the point they're trying to make but the way it has been cut out of context and posted with this title sets you up to believe they're morons while if you could have seen the big picture you might have a little more sympathy. It's so easy to get views and likes by putting people down, isn't it?
Wander Smut I think you've misunderstood. The students are just not correctly closing the circuit because they've only been given one wire. Every time you see those large domestic bulbs there's a single flex going to it, which could explain why they're just touching the wire to the bulb, hand them a small bulb like that used more commonly in electronic projects and they're more likely to remember that you either need two wires or you need to hold the bulb onto the battery. Incandescent bulbs like that should light up with a battery albeit rather dimly.
Wander Smut ah wait no sorry I've not completely read your comment closely enough. I don't know, I still think the point could be that people forget they have to close the circuit or just realise they don't actually have the necessary practical skills even though they understand what to do theoretically - connect the wire to the bulb. The bulbs should glow dimly when connected properly.
Wander Smut well then he analyzed the materials and figured out the problem and the rest didn't. probably got himself a job somewhere. maybe this was a test a company did to look for someone to hire. some of them didn't get the offer.
Now that they are Graduates, the first thing they should have done is gone into Salary Negotiations BEFORE doing the Job...
What the fuck... I thought they were talking about a 40w lightbulb. But a small lamp and a battery. Seriusly?
How many MIT graduates does it take to screw in a light bulb? LOL

I've actually seen this whole documentary once. Does anyone know the link to the full version?
I'm not an electrical engineer, I'm a mechanical engineer...
Was shocked by that answer, but explains alot about todays society.
What is basic and fundamental to you is not for someone else, if I say what a bitwise operator is for the one who posted the video she wouldn't know but a computer science person would know it. Similarly people who go to Harvard or MIT are not experts at everything, they are experts at their thing.
Prathik Rajendran M
Knowing a concept of _complete circuit_ is a bit more fundamental than bitwise operators.
It's like asking an electrical engineer to use ball bearing and axle to assemble a wheel, or architecht to make a sandwich. It's fucking fundamental and simple as shit, not specialization. You can't make a sandwich because you didn't get a cooking degree?
Even interior designer should be able to do that.
Pick 4 people that can't do it out of the 20 people you surveyed, put only one that can do it and there you have it, now everyone thinks every MIT student is dumb as a rock because only 1 in 5 can do it.
one even stated that she wasn't an electrical engineer, that gives you a hint about how many people they could find that couldn't do it.
The concept is so simple the excuse of not being an electrical engineer is like saying you're not an astrophysicist when you're not able to say which planet is 2nd from the sun. The concept is so simple you should go all day talking to people on campus without finding someone that can't do it...except that one student rolling on ecstasy that tried to suck on the battery. He's the only one that shouldn't be able to do this.
putty93010 no, it is not. It's a simple concept, but it's not a "everybody in the world knows how to do it" thing.
Everyone knows the theory, not everyone has done it in the past.
You may be talking about the simplest thing ever, but if you ask a bunch of people to do it for the first time, it's more than certain that a small percentage of them will get it wrong on their first try.
It doesn't mean that they are dumb, or that they didn't learn anything while studying, or that they don't understand electricity like someone said in the video. They clearly know the basics, they just don't have the "know how" to do it. It's not like the are connecting the wire to the bulb and sticking it on the ground, while leaving the battery out on the sun to 'recharge'.
It only shows that they never tried that before, because they never needed to, and probably never will.
I'm sure anyone of those who couldn't do that can do a better job in their fields than 90% of their competitors.
(and no, i never went to MIT, nor any other school in america btw)
Well I guess the term "dumb" is relative but children can do this (I think I was 7 the first time I did it). And Im'a hafta straight disagree with you. If they can't do this, they don't understand electricity and they are dumb when it comes to electrical concepts and practices.
putty93010 Yeah, and i'm sure you did it on the first try without anyone telling you how to do it too.
The rest of us mortals, have to learn how to do something before doing it.
the thing is even mechanical engineers learn electric circuits and physics witch include electromagnetism (god help me with that one)! And more, I think that basic circuit analysis is required like a thing every engineer should know or he don't get engineer title at all! So don't come with the excuse "Oh I'm just a Mechanical Engineer don't ask me nothing about electricity cause I'm not obliged to know" because not correct argument.
Calm down people. They are still some of the smartest people in the world, anyone can make stupid mistakes.

I remember when I was 7 years old I used to light the bulb by using only a battery with no wires at all, by scratching the top of the battery's cover you can access to the negative near the positive end .
This is not a question about electricity. All of them understood that they had to close the circuit in order to light the bulb. They expected two wires and thought the task would be really simple, but instead they were presented with a logic puzzle.
These aren't engineering students. The second semester of physics or the first semester of circuits requires knowledge like this.
Hell, in 8.02 (MIT's name for General Physics II), students are asked to build a motor out of a battery and some wire. These people have not done that course.
Falcrist The woman at 1:25 says that she is a mechanical engineer.
Falcrist Yes of course that's easy and believe me I am just a high school student.
Well, my brother is a topper PhD from MIT and I'm a bachelor from India, I still correct him on many things so, it doesn't matter where you've studied , it's about how good you are at something.
I have to admit that I had to think for a few seconds to see how to do it with only one wire, since normally you would do it with two wires. Under pressure, with a TV camera in my face, or caught off guard, and all of this at an important event like a graduation where my head would already be swimming, I might not have been able to figure it out.
Give me a 9V battery, and a small 9 or 12v bulb, and I don't even need the wire.
Okay this is just bad media. I'm willing to bet that the people they asked to create this circuit aren't even studying electrical engineering at all. One of them straight up said she was a mechanical engineer, and then the other guy asked for a tip, now that really doesn't strike me as the kind of guy who was studying electrical engineering. So asking the majority of a crowd that aren't electrical engineers how to create an electrical circuit is not going to get good results. Not just that, the circuit wouldn't work anyway because the battery is DC, and those lights are most likely AC, just like the majority of standard use light bulbs made in America. Even if the battery were AC(which isn't possible), it still doesn't have enough power to light a bulb like that. So asking a non-electrical engineer why that circuit wouldn't work is a complete bias on the entire situation. So good job America's media! You've gone and twisted the story again!
Thank you. Honestly, I thought I was alone here on the point about the media. I don't know, people just seem to have an *extremely* narrow understanding of what intelligence is, and the difference between intelligence and ignorance, intelligence and third party factors (such as having delayed motor functions, like myself), etc. Imo, they promote this way of thinking as it complements the average viewer in a way such that they ill want to tune in to the media station mor frequently, resulting in better ratings. It's just really frustrating arguing with people about this, because the argument is almost always either one-sided or the person I'm arguing with is an enormous hypocrite. Thank god the people I work with in my college aren't like that. :/
William Coburn The bulb used is a very large one. The larger the bulb is the more current it is going to need to be lit. A small 1.5v battery like that simply cannot light a large bulb. And by the way, a resistor is not the primary component within an incandescent light bulb. Nothing within a light bulb even sort of resembles the works of a resistor. Incandescent light bulbs use thin tungsten filaments in a negative pressure bulb, or one filled with a noble gas, such as argon, to promote the dissipation of light. When the current travels through the tungsten, the tungsten burns because it can not support the current passing through it. Resistors do not light up or burn when they come in contact with large currents. They simply dissipate heat. And also, in standard "household appliances", when using an incandescent bulb such as the one shown in this video, no sort of step down transformation or rectification is taking place. The only thing taking place is the burning of the filament from a full 120 VAC power source. And the supposed "small light bulb", is hardly small. From the looks of it the bulb looks to be around 12v. Of course a 12v bulb will not be lit up by a 1.5v battery. It's common sense.
William Coburn I understand where you're coming from, but don't twist my words. You know full and well what I mean when I said resistors don't burn up under large currents. I am referring to a large current in a diminished manor. Also, I never said that lightbulbs did not get hot, so you saying "You even say that the bulb filament 'burns' within the gas-filled vacuum enclosure, which contradicts your early statement since 'burning' implies heat dissipation", is, in a way redundant. And I have never seen a light bulb modeled as a resistor in circuit analysis. In no definition of a resistor that i've ever seen, has it exclaimed that anything that dissipated heat is considered a resistor. It isn't even really about the fundamental understanding of a light bulb. Especially when it seems as though most of the people being interviewed are not engineers of any kind. Sure, you could say that learning to light a bulb with a power source is a basic understanding of electricity, and that they should have learned that in middle school. But tell me, how many of the small things do you really remember in detail from middle school. For instance, if asked you to explain the tectonic structure of an earthquake, or how a mid-oceanic ridge is formed, i'm sure you could not tell me from memory.
3dUber An incandescent light bulb does not care whether it's powered from a AC or DC source. It will light up, but very dimly. Try it yourself at home. Get a piece of wire and hold one end to the bottom contact on a battery, and the other end to the side (screw) portion of the bulb. Then, place the bottom of the bulb on the top contact of the battery. The orientation of the battery doesn't matter. Tell me the results.
this is stuff that children should know how to do. I was taught this in grade 5, we were all given wire, batteries, and bulbs and told to play with them for 15 minutes and see if we could figure it out, then taught how and why it works... The problem is kids/teens/adults don't PLAY anymore
i did this shit when i was 7 in my grandpa car shop with car batteries, are these people serious
Rick Harrison One thing I've learned after 21 years, it's that even Harvard students can be dumber than the average American
Not necessarily dumber. Just learning completely different stuff, and sometimes too detached from reality and simple things. I believe they could explain things to you that you wouldnt even understand.
calcyss lol true, but this is something they should've learned in high school if not first year right? I mean, I learned this in grade 9 science and grade 12 computer engineering.
***** Well i personally never learnt this (im German), as i slept through it in school lol :D
But anyone with a basic understanding of physics should know *why* this doesnt work, or rather why it doesnt work the way they are doing it. Closed circuits are a pretty basic concept.
Rick Harrison An opinion? The best I can do is not give a fuck.
does the video continue? it seemed like it was cut short and it seemed pretty interesting. Is there a full version somewhere?
The very first thing that came to mind was "how much voltage does the battery provide, how much voltage does the lightbulb require, and how much resistance does the wire have?" Of course it's possible to do it, but only IF the battery can supply enough to overcome the resistance of the wire and the lightbulb.
Michael Etzel P = V^2/R all day
If the interviewer actually had shown in the video how to light a bulb with the battery he gave them, the video would have been correct. Is that supposed to be journalism?
Pablo Blo they showed?
Pablo Blo wait what? no you misunderstand, the interviewer wasnt teaching them how to light a bulb. which is something taught to 6 year old children in the UK and demonstrates a basic fundamental understanding of the manipulation of electricity. They simply provide the means to light the bulb and ask a bunch of graduates from the most prestigious technical college in the US if they can light a bulb using skills they should already have.
Pablo Blo
I disagree. An engineer should know that a 110 AC bulb won't work on a 9 or less Volt battery. Noone asked what type of a bulb is it (one could dissassemble a 110V LED bulb and make individual LEDs light up with a normal battery), noone asked what type of battery, the idiot on 1:39 shorted out the battery, one student assumed they failed when it didn't work without even asking can it work.
Those are not engineers, those are kids with engineering diplomas and a disgrace to acctual engineers.
I understand that to people that aren't engineers this seems harsh but remember: engineers design the stuff you buy, and one of them is now an idiot that tried to power something with a battery by shorting the battery out.
Source: i'm an engineer (a mechanical engineer to make it even more ironic)
+Fleksimir I think you're being too harsh, based on a cherry-picked video with nervous people being asked to do something new on camera.
We all have that part of the course that we hate and just dish out on the exam and forget, only to realize later that we need it. Their skill on this particular practical problem this one time can't really be extrapolated to their skill on everything else.
+Pedro S
You are not wrong and you definitely have a point.
Infact i would say the same thing for lots of other things students don't know to do.
I think i just consider this to be too basic to fail.
My engineering faculty is only 27th in the world, but at least I can make a light bulb shine
+Matthew Patroni Mine is not even on the chart, This is just propaganda though.
Don't blame the teachers. This is all about a society that values 'bits of paper' above actual knowledge.
They teach this in 8th grade science and I thought it was one of the more fun things in that class but they only spent like 2 days on it cuz it is so easy. Now I'm in 10th grade and I took digital electronics as a math credit and just a few days ago the teacher gave us a computer program to model circuits and I finished early so I made a simple binary calculator for fun.
Which country you are from ?
@@indianbrave I'm in the US.
oh my gosh! People don't go to school to learn, we go to get a piece of paper that employers recognize and will then hire us. Otherwise businesses would hire all those crazy asses from Russia
Andy Peterson Exactly why college and state "education" is a scam made to deceive people.. separating the sheeple from the open minded ones..
Hybodus Shark Ok, so if you're so open minded, try convincing the employer you're up to the job without a degree. Smart people still need official recognition or nobody would hire them. It's only a scam for dumb idiots but for smart people, uni is worth it.
Andrew Wei What employer? If they judge ones status based on a so called 'degree' then there not worth my time now are they? Plenty of other jobs out there depending on where you look and how you live and spend your money and so forth.. yep Definetly worth busting ur ass in uni for a worthless piece of paper.. Enjoy wasting your time in college bud.. Very well worth it for you..
Actually, I'd very like to get employed without a degree too. Please tell me how.
Andrew Wei two words: MOTHER RUSSIA
I never saw anyone explicitly state that they are MIT graduates in the video, and I think that the uploader got rejected when they applied and is lashing out.
Something I remember learning in kindergarden. we lit bulbs, powered dc motors, and made electromagnets.
Jonathan Thomas
In the state of Texas they save the harder stuff for college. ;)
I know right! I broke toys to see how they work >
*****
When I was in elementary school my parents worked for a hard drive repair company, and whenever there was a bad drive that already had the data recovered from it they would let me take it apart, and take out the magnets. I ended up putting two of them together on my ear and had a hell of a time trying to take it off... at least I was in style :P
Blake Bowers omg haha, those are strong!!
So according to Prof Sadler, if a person cannot complete a correct circuit with a battery and wire to light up a bulb, then "EVERYTHING ELSE HAS PROBLEMS"
Really? That's how you test intelligence, knowledge, wisdom and creativity??
Well you know what you can do with your little electric circuit test?
What a ridiculous demonstration at a graduation ceremony.
Peter Kan Yes Peter, that's how the world test intelligence. If you use something as a fact or have hypothesis to create something. if that fact or hypothesis is already wrong then how do you expect the final result to be correct. We have learnt that nothing can travel faster than the speed of light(theory of special relativity) but now scieentist have discovered neutrino's which can travel more faster than light. We use special relativity as a fact but now its proven wrong which means everything related to special relativity or use special relativity is wrong.
Why do you think it's ridiculous? Just because it shows the truth. I think graduation ceremony was the best place to demonstrate this,
+Rachel Matthew "Scieentist" have NOT discovered "neutrino's" that can travel "more faster" than light. Better work on your neutrino knowledge, along with your English spelling and grammar.
+Rachel Matthew actually that particular measurement concerning neutrino speeds has be debunked and sorted out. You need to keep up with the latest developments and follow things through right til the end.
You should apologise to everyone on the internet, withdraw your remarks and ban yourself from using TH-cam for 48 hours
+Lord Kaiser apologise and ban yourself from using TH-cam for 48 hours
+Peter Kan man just don't talk about neutrino specifically. You get what I wanted to say. Now that you don't have a point you are just pointing silly mistakes which I just used to convey my point. Do you even know how to debate?
Ban yourself from TH-cam. so dumb comment like what were you even thinking. Just ban urself frm Internet.
that's what happens when you are taught American Studies and Art at MIT
small sample size.
EDIT: Literally two seconds later in the video they showed what I talk about below. I didn't watch that far in before writing this stuff, though it's good to get a confirmation that it was correct.
I'm not sure which goes where on the bulb, of the - and +, but I know one part has to go in from the bottom and the other from the side of the socket on the bulb. Put the bottom part of the bulb on to the corresponding part of the battery then take the wire and have it touch the side of the socket on the bulb on one end then the other end of the wire to the opposite side of the battery from where the bulb is touching. Voila. If I get the - and + wrong the first time I'd simply reverse and surely get it right the second time.
People who couldn't get into MIT watch this to feel better about themselves
Since when do u need an electrical engineering degree to fkin light a bulb ?
This is some shit all of us should have learned by the age of 8-11
I was fkin breaking atari game consoles and taking out the PCB and playing with it when i was 10.....
it's basic knowledge people
How many mechanical engineers does it take to screw in a light bulb?
The really scary part is how confident these students are in their own abilities. These students have played the game, and short-changed themselves of an education. Understanding isn't a requirement for success.
The big 120 volts light bulb sure lights up on the 1.5 volts battery but we don't see the light because it's too weak for our sight, but, if you observe the light bulb through a cellphone camera which is infrared sensitive then you will see it lights up because the filament gets a little bit warmer and irradiates infrared radiation.
First off the size of a bulb is not necessarily directly proportional to it's voltage requirements. There are small bulbs that are 120v (usually in a night light) and there are very large bulbs that are 2.5v. It was clear (at least to me) that they weren't trying to trick anyone.
Second, a MIT graduate should be able to read. The voltage rating is printed on both the bulb and battery so if the battery couldn't illuminate the bulb, them even attempting is quite humorous.
And finally unless your phone camera lens is bigger than your dilated pupil, it cannot detect wavelengths bigger than what your eye can see (infrared). Most infrared cameras have a lens diameter of about 5 inches. I'm guessing you meant electromagnetic radiation in the infrared spectrum, there's no such thing as "infrared radiation"
putty93010
First; I know that the size of a bulb light has nothing to do with voltage. I just wanted to be descriptive.
Second; Being graduated at MIT is not a guarantee of basic and practical knowledge at all. School does not make students.
Third; The size of a lens has nothing to do with detecting bigger or shorter electromagnetic wavelengths. Most of cellphone cameras are able to detect infrared radiation. Infrared wavelength is even shorter than microwave radiation so it can easily pass through the tiny lens of any cellphone camera.
¿Why don't you do that experiment at home?
Greets.
"unless your phone camera lens is bigger than your dilated pupil, it cannot detect wavelengths bigger than what your eye can see (infrared)" Bullshit!
Martin O'Donnell
Your'e right, that's bullshit. This guy, Putty, knows nothing about physics.
Greets
Wow this is just common knowledge, I think I'm going to MIT now! If they graduated surely I can.
Break the wire into 2 separate pieces & connect them individually to +ve & -ve terminal. Then connect the other 2 to bulb & it'll light up. (3rd grader)
You don't even have to do that. Connect one end of your wire to one terminal of the battery and the corresponding terminal in the light(bottom or side of bulb) and connect the opposite battery terminal to the other end of the bulb and voila, you will have light. Given that you have enough current for the given light bulb.
Wasif Ali That is what exactly I was thinking. I thought at the start of the video that the journalists were fooling the graduates. When I was watching the video I said to myself "Cut the wire into 2 pieces" and light it up. Basic electricity concepts. I don´t know what kind of bulb the journalist had, but I am sure the battery is a 9V one.
MChiribogaD Pardon me but USA high school system i.e GED/Diploma has so many flaws regarding adequate academics skills given to students before going to university as compare to those in UK (Gce & Gcse's) which I've studied. Not being ostentatious but for us, this is a breeze.
Wasif Ali They went to Harvard....the problem is not with the education. It's with those students.
Wasif Ali I think the US education has some flaws considering the fact that the US is considered a developed nation.
Countries located in Europe actually give more advanced programs that they do give in the US. Even countries in Hispanic America give more advanced programs than in the US. I have a friend that was applying for the UK and she was not admitted for getting into an university because the US curriculum from her school didn´t covered the programs that the UK high school system covered, thus, she applied for a foundation year. USA considers Calculus as AP,while in other countries is just part of the common curriculum.
I am from Ecuador, and when I moved to Santo Domingo, DR, I went to an US school ( I don´t like to refer "American" just for the US but rather for the whole continent) and when they started giving Chemistry it was literally everything I saw last year in my last year in Ecuador, Math the same, and Physics...no physics bro! In senior year we just had physics, and guess what...the majority of topics I already covered them in Ecuador during 10th grade while in the US education they give them in 12th grade. In 11th grade I didn´t had physics. I was so sad, because physics is my favorite subject, so I decided to self-study physics with my physics book from Ecuador (Física "Paul E. Tippens")
So that´s what I think. Best regards.
Today I learned I'm more intelligent than MIT graduates.
Those parents wasted their money.
Where is the rest of it?
did this experiment in primary school, age 9..
Well, filament bulb is only a resistor, it's glow depends upon its voltage/potential needed. Here, potential matters only. Nothing else 👍😊😊
Exactley hahah all those butthurt students try to comment that it wont work regardless, just shows how stupid they are.
What do they care their bulbs will be on chandeliers paid by their 6 figure salary
best answer "Yeah, I can certainly try..."
The Institute is too focused on making synths to worry about light bulbs!
ad victorian brother.
To all the people defending these students... most of them weren't hooking the wire up to each end of the battery. It doesn't matter how big the lightbulb is or what the quality of the wire is; if they don't know the basics to making a running current, then they're stupid.
Austin Fisher The experiment was designed not to work. Just so you know, a 1.5V D cell battery can't light up a 60 watt light bulb, which is designed to work on 120V AC. The only fault with the students is that they couldn't explain why the bulb couldn't work, but the reporters completely misrepresent the situation to make them look like dumbasses. An example of this is the fact that they used a bulky D cell battery to make it look adequate enough to light the bulb, when in fact it has the same voltage as a small AA battery. Look at 2:00. It only worked for him because they used a smaller bulb. And even then, look how little it's lighting up! You can't possibly expect to produce the same, let alone greater, results with the bigger bulb.
Austin Fisher Very true!!!
FunOrange Bro it's not about whether the bulb was lit up or not. It was they approached and answered the question. Sometimes if you learn too many complex things, you forget all about basics. None of them had a good approach, confidence and a fair answer. They literally had to think for a minute to answer the question which is very wrong as an engineer. This is the point where one person gets the job in the interview and another doesn't. The way you answer, your confidence, each and everything matters. Each and everyone was thinking like it was very hard math problem and after all thinking they were like ya they can do it.
Exactley
@@FunOrange42 of course it works, you just showed how stupid you are...
this was about electric principles, I learn and make it on school, but must required certain conditions, the battery power, the power requirement of the bulb and the conductivity capacity of wire.
+Otto Rivera
Yup!
And I'm only 19 years old ... hell I fix electronics things as well, and I haven't gone to college.
Just goes to show, that with the right mind/thinking style, anyone can easily do anything.
to be fair to them, in the general physics department at my college we used ledsor a light bulb with the wires preattached.
LEDs or**
I interpreted the video as saying we build knowledge on a foundation that we were never taught to have. I, for one, have never been explicably taught many things that are supposed to be self-evident, but had to learn backwards in a way by doing higher level work. Of course they know how batteries and electricity works, but especially at that level, they are expected to know basic things, but are never taught those things out of need to cover bigger picture topics. I am thankful to be grounded with people who aren't as higher level as I've been taught and I learn just as much from them about the world that I never could have learned in my classes.
1.5 volt is supposed to light up the big bulb? why did some of them get the small bulb?
David Oliphant I have one of those big bulbs. it's a little dim at 1.5 volts but it works at that voltage
my brother asked me the question the other day, I scratched my chin for five seconds and told him I could put one end of the battery to bulb's contact.
I only found this video afterwards.
Wow that's embarrassing. I was doing things more complicated than that at age 7. Shows good grades aren't everything.
