Unfortunately, for this specific abnormal subspecies, the abnormalities are such that any concept of focus and/or attention span have literally devolved and regressed, almost entirely, down to the *thousandth decimal place* which has rendered all faculties inoperable, to a virtually non-existent state, leaving in it's wake a dramatically reduced mentality, resulting in a complete inability to reason, analyze or interpret even the most minute of observations.

@40:00 For those interested, the Helium "problem" refers to stars early in the age of the universe with only about 1/3 of the helium expected, helium being produced by fusion within stars of hydrogen. Measurements showed more carbon, nitrogen, and oxygen in the stars than expected, which leaves open this question of where did all the helium, one of the most abundant elements in the observable universe, come from? As this measurement of helium came from a small sample of stars it could simply be an anomaly, or if actually representative it could suggest that there was some kind of secondary fusion taking place outside of the stars converting hydrogen to helium. I'm not an expert but I believe that these days the more common belief is that how much of a particular element stars produce is based upon their characteristics like their mass.
Mr. Cook- why you chose to end your life is a mystery to me- but watching you set up and demonstrate the two slit experiment drove me to be a physics teacher. You made a difference…you did… because I have been blessed to have taught students who have accomplished so much ! You truly did change the world because you inspired a basic kid to do so much better…

What an incredibly simple explanation of a mind-boggling idea. My first psychedelic experience changed my life. This video has changed my understanding of the world. I have no experience in physics at all... But this video has Open my mind to a world I did not know existed.
There is something about how Prof Khalili explains things that make me nod my head as if I understood things which i could never comprehend, like ever.
@@hennersss I like your modern art analogy but personally, I think most of modern art is shite, things like a fucking brick wall that to me is just a fucking brick wall and I am prepared to say what I think here, not pretend to see some non-existent hidden meaning. Good luck to the artists if they can earn a living conning middle-class prats but I am not having it! As for Prof Khalili's explanations, they seem perfectly clear and understandable to me as they are after all aimed at the layman, not other scientists. The fact he never uses or talks in depth about the mathematics behind all of Quantum theory shows this!
He is easy to understand as he is aiming at explaining to intelligent laymen, not other scientists and that he never delves into the mathematics behind quantum theory shows this. If you cannot understand him why bother listening? Perhaps you should stick with cartoons! 😜
I studied quantum physics in college and have watched endless amounts of quantum physics related content on TH-cam, and I’ll say the card dealing example is one of the best ways I’ve seen Bell’s experiment explained. Made it very clear for someone seeing this for the first time or even anyone really struggling to understand
I never liked the school.But I loved physics lectures.I left the school and now I am watching quantum physics and can easily understand. Thank you, Sir!
If Quantum defies all logic, then it cant possibly be understood by logical scientists. If you can figure out Quantum "rules" then its not defying logic is it. BUt in reality Quantum is hocus pocus mysticism repackaged for the gullible idiots of today.
would the study of quantum synthetic vibrations be used to create low level electronic vibrations to generate artificial vibrations to Smellivision to enhance the modern television experience? It would be a massive undertaking but I think it would be possible given time to generate a library of electronic created synthetic scents to insert into images.😮😮😮

Couldn't agree more! Definetly my favourite science presenter, I WISH he would do more. So easy to listen to, I've watched most of his videso several times.
@ 28:00 You can enjoy Jim Al Khalili giving his lecture about Quantum Mechanics on a bar counter at the sound of jazz music American Jazz Musicians were exporting to the whole world. That’s really the modern Physic at its finest. Really! Congrats Mr. Khalili 🎉🎉
Yes we know… if they thought physics broke down at the quantum level they wouldn’t be doing experiments to try & figure it out. The reason he put ‘When physics breaks down’ instead of ‘When our understanding of physics breaks down’ as the title of the video was to keep it short & not have a long drawn out title. It’s not because he literally thinks physics won’t work beyond our understanding….
His honesty isn't good enough for you? You are right, of course. Our understanding (given materialistic assumptions about the nature of ALL reality) breaks down. Case in point, Einstein said, "I'd like to think the moon is there when I'm not looking at it". Einstein's intuition was correct. There is a deterministic aspect to reality that makes it objective to you and I. Our observations and measurements, however potent they are, do not define EVERYTHING. But this does not mean that everything is determined mechanistically. Conscious agency can also determine and define (measure), according to purposes independent of material causality. You are fooling many with your assurances (look at all those thumbs up). But not I.
Thanks for re-posting this fine science material featuring a favorite, Prof Jim Al-Khalili. People will watch the Big Bang Theory, TV Sitcom again and again. I like re-watching good science shows.
Sir Al-Khalili l have only watched 3 of your documentaries Shock and awe the story of electricity , What is energy and now The science that defies all logic . Science for me serves as a source of fascination with your elegance in explaining concepts and introducing to me many other great scientist that contributed to the discoveries of scientific laws we now know to aswell as technology it is safe enough to say you have excited me even more and make me want to be apart of this great voyage to understand the observable and un-obsrvable universe but l shall take a path in EE as l am deeply interested in invention. L am currently doing the tenth grade and physics mathematics and chemistry are my favourite subjects as pondering on the concepts discovered in these subjects is what makes me a science enthusiast. Thank you and your team for putting your time to make such films .
I've seen all the laws broken here on Earth: time, motion, potential energy, kinetic energy, gravity, all of it. I watched time stop for all objects except me, same for gravity and motion. A clump of dirt flew in and was frozen in front of me. I also forgot that I was in the middle of a car accident and the car was in the air as well as we hit an embankment at 85 mph. All I cared about was what this thing was that flew in the car. It looked like dirt but dirt doesn't fly and stop. I had to scoot up to see it better. I still couldn't see it so I had to loosen my seatbelt to scoot all the way up. I put my eyeball right next to it and saw that it was a clump of dirt. Then I remembered about the car accident and had a quick panic attack. I checked my seatbelt and looked at my friend. His face was frozen just like the sand. I saw his seatbelt on, then boom. Time came back on. My friend didn't have it happen to him. It was like pushing pause on our environment including my friend; pausing everything except me. I stayed in normal time, gravity still worked for me as I wasn't floating. The sand looked still floating in the air. I figure that it took about 15-20 seconds to scoot up, then again, then freak out, finally check our seatbelts. It wasn't an adrenalin rush like everyone says. I was completely calm and normal until I remembered what was happening and realized that time was stopped. Then I freaked out, but before that I was normal. That is one of like 25 stories that happened to me. When I was ten years old, it happened in front of my parents. I was doing my homework and the phone started ringing. I looked at my dad and he didn't move at all. Looked at my mom, the same. I get up kind of upset nobody was getting the phone when I was trying to do my homework. My dad looked at me like WTF and my mom got up from the other conjoined room to see what I was talking about. When I got to the phone and was reaching for it, it rang for real. The two rings overlapped each other causing a much louder ring. I was instantly sick and going to faint, but my mom caught me by my cheeks and told me I had a gift of ESP. I slept for a day and a half. There's two. This life is an illusion, a simulation. I know that's hard to believe unless what happened to me happened to you, then after thinking about it for 30 years, you would have the same conclusion as I have had. It has to be a simulation. All of you are simulated. Why am I writing this then if you already know that? I guess for the chance that someone may know how to get out of the simulation. The exit.....
Sir, your explanations are WONDERFUL! I have always thought of reality as obeying laws that are sensible, but quantum physics gives the impression of not doing this. String theory attempts to make things a bit more sensible, but probably is not the answer. In any case, the way that you put real world explanations to these things is so very good.
String theory was hyped as the answer just a few years ago..... it solved so many problems. Alas, as one absolutely final theory to explain everything goes down the plughole, another one emerges which is next final theory to explain everything. What atheists need more than anything are theories.
@jk-video2716 much of the physical world follows logical laws that are comparatively easy to grasp. And our faith in the uniformity of nature (at least in terms of its being logical) is well founded as a result. But if a conscious observer is involved, in order to understand how more difficult problems are logical, we would have to comprehend the purposes of the observer. And that may not always be possible.
The best video I've seen on quantum physics! Congratulations! My soul calmed down, because I thought the same way about this topic, even though they taught it differently at the university. I'm just an electrical and sound engineer, retired but still active. With a device I made that works on quantum physics principles, I can greatly improve the characteristics of cables, speakers and other materials used in audio technology. Even the high-speed cables used in IT (CAT 6 / 10GB / sec). I wish everyone who participated in the making of this video good luck and good health!
For about two hrs it was a great experience and at time when got out of trans, I found myself a dump as I was seventy years back.....a high school graduate.... thanks a lot....a great experience.
There is no reality to perceive without awareness of the perceiver percieving “reality”. As my father often said “reality is in the eyes’ 👀 of the observer. ❤❤❤
Indeed. I don't know what the fuss is all about 😅. We shape our reality according to what our attention focuses on. Makes perfect sense to me. Where's the mystery?
This is the third time I've seen this exact documentary, featuring Jim Al-Khalili, under a different name. I can't remember what the original production was, but the second time it was published under Spark. The fact that it's now showing up on this channel with none of the original production logos does indeed make this look like stolen intellectual property.
Jim Al-Khalili, I did my best to follow your excellent lecture explaining quantum mechanics in layman's terms. As try as I can, however, I still do not understand why it is that Bell's experiment showing sums less than or greater than two answers the question whether Planck or Einstein was right in explaining the uncertainty about entanglement and whether there is spooky action at a distance or some hidden variable that underlies and explains entanglement. Is there a chance you could explain why knowing the answer to be < or > 2 is outcome determinative?
This is just the explanation about quantum mechanics I was waiting for in years. Thank you for that Professor Al-Khalili. In my understanding Physics is aimed at associating models (numbers and equations) to the real things. Models are there to predict the result of future experiments, which then prove if they were right (aka: applicable) or wrong. So I have no problem if a (relatively) free standing electron, or a crashing electron on a detector follows the particle model, while a fast traveling electron fired by the gun follows the probabilistic wave model. What I miss in this case is a description of how properties of the electron are modified when it is "fired" (or: what makes it "evaporate" to a probabilistic wave). Similarly, how the electron properties are modified when it is "detected", "measured" or when the probabilistic wave "crashes" on some obstacle to crystallize again as a particle at a (somewhat predictable) random place in space. Studying these transitions could be more profitable than arguing on "which reality is real". Concerning entanglement, did someone look at it as two crystallization's of a single wave ? The video suggests that the second coin continues to turn when the first one is fixed. Isn't that misleading ? when the first one is "detected", what if the second one has been displaced out of reach of a detector ?
But what an admission to make, that" QM defies logic".. In other words, its not rational. In even more words, that means that it cant be studied by rational logic humans, who's only way of discovery is by applying the rules of logic together with a rational understanding. So maybe we should let patients on mental hospitals study QM? because they are irrational and illogical? And their thinking can not be understood by those that are rational and logical. But maybe scientists ought to reconsider their interpretation of those few observations that led up to the belief that there was a new science at work, namely QM. Its more likely that they are flat out wrong. But too pig headed to admit that they have been fools. Another bit of "science " that is irrational and illogical in everything that Einsteins said. Few people have realized this fact thought. Meantime is a great article of faith for the believers.
if you were young for Harry Potter, you do not have much experience as an "older" person. Take that from an old Baby Boomer. You still have many adventures to live through. Too many to list here.

In 4th year highschool one of my favorites is Physics. Two Sections A and B attended these class altogether about 50 senior students. In short quizes involving formulas I beat the best and honor students so do in world history subject. My physics teacher was surprised why I was leading while honor students tailed behind me. But that inclination halted in college my course is different from my academic interest.
I think its very interesting that the electron produces the same pattern as a photon because it has charge. If we say that the electron is in a superposition before interacting with the detector, cancelling out in areas of desrructive interference, the question arises whether charge would play a roll. But it clearly doesnt. The wave function does not account for the particle's own charge, but the charge of other particles. How is this distinguished? And ill point out that photons can exist in the same exact state as bosons are exempt from the exclusion principle. So its not as if it is somehow bouncing off itself in a state of superposition. This is truly bizarre and unique.
Well I guess it's like meat in the supermarket. The first date is when it's sold as a steak. Not getting bought it's cut into pieces getting a new date as meat for a stew. Not getting bought it becomes minced meat getting a new date. Not getting bought it becomes sausages and a new date. Not getting bought it could become a part of a pre made dinner only needing a little heat to be eaten. Not getting sold it doesn't get a new date but a considerable discount. Someone is almost bound to buy it. Thinking it was only made yesterday - if I eat it today it will be safe and almost as good as new. It might very well be safe - it's just not "fresh" and started life earlier in another context. Essentially the same and legally only a few days old... Luckily the videos ages well without a sense of being outdated. If you missed it the first few times around - don't worry - it will find a way to you one way or the other....
The proton itself the nature of light, our consciousness ect.. So close and yet so far away. 1 and 0 at the same time until it's observed or measured. We are living in exciting times for physics. Good job.
Listen O believers....The big deal is God himself...the omnipotent the omnipresent the ultimate/obvious/absolute observer of all the particles of univrses.....so all existence remain in place ... When no body is seeing the creatures or existence......God says this in Quran in these words ....chapter 53 Fussilat ..verse no 41 And does it not suffice as to your Lord that He is The Ever-Present Witness over everything? We shall show them Our signs in every region of the earth and in themselves, until it becomes clear to them that this is the Truth. Is it not enough that your Lord witnesses everything?
Jim says that wonder is just how quickly the tadple turns into the frog and clearly this is true. But also, the wonder is just how slowly the same thing happens. During these weeks of transformation all states of the change must continue to be life-viable or it would die. It's one thing to gradually change a car into a boat over six weeks, but quite another to say that at all stages of the change you can use it to get to work each day. Amazing!
The biggest problem with physics is observation and how a particle is coupled or not since our observations can only see what is in the past of what we are looking at......since light has a limit in vacuum it cannot travel faster than itself and there is always a length of time and distance that always is part of our calculations we can only view something as it was and not how it is from its own place in space time......we can never observe anything unless it from the past no matter how small the length of time which also means time would have to be infinite
@@DoseofScienceDoS......it's how we observe things is our trouble.....of course you probably have the answer......and yes it is quantum physics and it rules the universe and the Planck length is the smallest possible thing we can observe......kinda like how we jumped from optical to electrons for seeing things smaller than a photons wavelength What's your genius suggestions
@@midbc1midbc199 explain what a length of time is. Because a length of time isn’t a real thing. Do you mean distance or did you make up some word salad?

For those who don't know, this is where Schrodinger's cat comes from. He and Einstein came up with it to show how silly "spooky action at a distance" really was.
I'd always heard that "spooky action at a distance" was how people thought of Newton's ideas about gravity, at first. After all, how could the Moon affect the Earth, and vice versa? But maybe I heard wrong? You never know.
@@Bill_Garthright I can't say you're wrong because I don't know for sure, but I just looked up "spooky action at a distance origins", and found references only to Albert Eintein having coined it. I also searched for any refernce to Newton in the phrase, but all I found was that Newton said that gravity caused "Action at a distance", with reference to the earth/moon attraction - but no indication that Newton thought it "spooky". Incidentally (fun fact), Newton declared that he saw further, because he stood upon the shoulders of giants (a rare moment of humulity from what I can gather). When Einstein was asked by a reporter if he stood upon the shoulders of Isaac Newton, he replied "No. I stand upon the shoulders of James Klerk Maxwell". However, I did find an Einstein quote about Newton : ""Newton, forgive me," wrote Einstein; "you found the only way which, in your age, was just barely possible for a man with the highest powers of thought and creativity. The concepts which you created are guiding our thinking in physics even today..." And, of course, he used calculus - though Leibniz should probably get the credit for the calculus we use today.
@@casteretpollux Huh? Sorry, but I don't understand what you're saying there. How is that a reply to my comment? Or maybe you accidentally replied to the wrong thread? That happens, sometimes.
I love how they framed the most important battle about existence of reality into a dance hall of the 20's. No matter how important and how big the Bohr - Einstein battle was the majority lived with even more important agenda. Dance, flirt, gossip, seduction,sex. I love those two planes presented together.
Two questions come to mind watching this. First, what does 'the other particle simultaneously changes' actually mean in a relativistic universe? They are separated by an interval, so we can change the time and distance by switching inertial frames. Second, the robins. Assuming the electrons are entangled, how did that happen and still guarantee they ended up in the correct positions?
Im new to quantum physics and im addicted. i became interested because i feel like our picture or outlook on reality is completely flawed, so i came to get answers.
Time is fascinating. I worked the subway stations for nearly 10 years. From one end of the city to the other. Every so often I would notice the city would be saying that, "Today just flew by" or "The day was just dragging along." How can an entire city, with no interaction with each other until they used the subway, complain about the same time paradox unless it was effected by it? Maybe a time distorted bubble the earth passes through in its revolution around the sun. Maybe random waves of time distortion hitting the earth? Maybe they're given off by the sun. Maybe they're from outside our Terran system and reach us in intervals. ???? 🎶Ti-i-i-ime, is on my side. Yes, it is!🎶 If you can think of a better way to do a blind survey of an entire city, in the small window of opportunity, I'm all in. Until then, I invite you to spend a couple years in the subways. Between 2pm-10pm and you'll see for yourself. Just listen as an entire city gets off of work and gets out of school. You'll see it's more than a, "coincidence of circumstances."
I think we need to consider the ground radio-activity resulting in alpha-particles, near volcanos, and even in volcanic ashes that spread to long distances when we think about the mutations due to protons. This could also explain how billions of different species of different sizes and shapes were born to the world many millions of years ago when the ground radio-active levels were high due to thousands of volcanic eruptions. Of course then nature applied natural selection explained by Darwin.
I loved the scene of club house set-up at minute 20:30, where Prof Al-Khalili 'time traveled' himself back into the year 1922 to explain on the light theory. Really nostalgic and classic moment.
Yes, a 3D reality, residing within a 4D space-time reality. Two radically different sets of laws of physics. Examine the 4D laws of physics from a mere 3D point of view, and things seem very bizarre indeed. Again and again, you will see the 2 slit light experiment being discussed or demonstrated, and how minor changes can determine whether you will end up with an interference pattern, or not. But never will they mention that these minor changes determine which set of laws of physics come into play. HOW ODD OF THEM ???
This is a BBC documentary series "The Secrets of Quantum Physics" first broadcast on the 9th December 2014. Not acknowledging that fact is copyright theft. Reported.
_As Johann Wolfgang von Goethe stated: “Science is very hampered by the fact that one focuses on what is not worth knowing, and with what is not knowable”._
Anything involving faith and beliefs is involving a god or gods. Science isn't absolute either. You can study doing experiments making a theory plausible. There are many levels of scientific proof. It can relate to a very specific subject under specific circumstances. It could be applied in a wider context being a general law/theory but not being specific. In fact it could be any combination thereof. Theories are more often than not a working model applying the knowledge in a way that brings understanding - but not entirely correct. Engineering is science put to practical use... cutting corners - things have to be safe and working. You add a little here and there to ensure things are safe and working properly in a given interval of time. Some scientist believe in God but see no conflict. As scientist they speak upon matters they can prove or make plausible. Religion is another dimension. Copernicus discovered the Heliocentric System. The sun being the middle of the Universe and everything else being in orbit around the sun. He himself was a devoted believer. He saw it as a form of worship understanding the inner workings of Gods creation. Adam and Eve took a bite of the Apple of Wisdom - why they were kicked out of Eden. Having knowledge they now had to use their intelligence to make a living. Just like young people graduating moving away from home. As far as I know most religions encourage getting knowledge (both sexes). All major religions have it including Islam. Traditions and cults derived from the original scripts may have other rules - but they're not found in the "original" religion/scripts. Adam and Eve were basically told to use their brains. People using religion to debunk science are just as wrong as people trying to debunk religion with science. To different systems you can't apply rules from one to the other. The simple saying of comparing apples to oranges. They're fundamentally different. You can't compare. The measuring sticks are different as well.
The physical is only the tail end of an event that is originally a psychic event. An object is a solidified thought. An event is a motionized thought complex
Ive soved Einsteins “Spooky Action” riddle. Space and Time are being pressed up into your face at the speed of Light then returning back instantaneously thus, resulting in the illusion of time. “ Time is but an illusion.”
As we start, as an electronics “dude” I can’t help but note that the light bulb as a vacuum tube lead to the first electric switch the vacuum tube! They knew about the transistor or diodes for yrears before they figured out how it worked. It was expected to create energy which I did not but led to switch controls witch inject power control by design. Based on this , we are half way through a next such tool.
I am ignorant of sciences, but curious and always inquiring about some of the regular situations in my everyday routines. In this video, my doubts have increased, and I am more skeptical about whether I exist or if it is just being a part of something undefined, uncertain, and surreal. How knows!
Has anyone else noticed this 22:20? "But when I observe you, you change your behavior". Lol I love that clever peek into an important aspect of quantum physics.
QM doesn't defy logic, it defies our normal understanding of matter. But our normal understanding of matter is merely a construct from our representation of the material world through our senses, which is itself at best an approximation of material behaviour at a much larger than quantum scale.
This stuff is so fascinating to me...I love to think about how everything we know and have discovered is from the human perspective and wonder what what diffrent things the really is and what else is out there that we will never know or understand. Because everything is from or point of view. Crazy if u really think about it. Would love to really know what everything really is and how it was made and where and why we are.
I was sweeping while listening to this and just in the fist min as I swished the broom and all the puff 💨 of dust traveled though the air I imagined the quantum world and what it would’ve been like to be in there and what it would be like. Good stuff, the weed of course👍
Keyword, "Professor". The one who professes (to the layman public). There is a section in professorship applications about public outreach. For most of us scientists, this section is left blank. Really! Scientists are mainly really bad at public outreach. We just do our research hoping no one in the public ever asks what we do for a living, partly out of fear of trying to explain. Jim Al-Khalili amazes me. He does excellent science and also does excellent public outreach. Must be an alien. :)
It would seem that if you needed to hit a target that using a large wave might not do any better, it might have more energy, but it might also miss the target all together. If we put a car on a race track and we tried to send someone across the track, when the track is long it is easier to avoid a collision. As the track gets smaller and the loops occur more frequently it gets harder and harder to make the crossing while avoiding a collision. At a certain frequency, it becomes almost impossible to make the crossing without a collision occurring. Yes we could increase the mass of the race car, but if it doesn’t result in a collision, the additional mass doesn’t have a meaningful effect. However even using a tiny car that is moving fast enough we can almost guarantee a collision will occur. The larger question, is does Increasing the intensity ever result in an expelled electron? While it might be unlikely to produce a collision at slower speeds, it might still occur infrequently. Similar to a neutrino hitting a nucleus of an atom of water. Does the photoelectric effect ever appear to spontaneously happen? It would seem like if the waves are going too slow, it would happen very infrequently if ever. But it seems that using a bigger wave is akin to adding more mass, while using higher frequencies is akin to increasing velocity. And 1/2*m*v^2 would mean adding velocity is more effective means of increasing energy.
I LOVE this content. It not only helps me sleep but I feel like I am learning something. Science. It works bitches. Otherwise imagine having to live by moonlight at night and communicating by banging on logs. Which is about as advanced as us hairless apes would be without science. Embrace the truth or what most likely is and hang on for the ride. It is spectacular.
Now this is what youtube is all about! 2 hours of pure bliss.

Unfortunately, for this specific abnormal subspecies, the abnormalities are such that any concept of focus and/or attention span have literally devolved and regressed, almost entirely, down to the *thousandth decimal place* which has rendered all faculties inoperable, to a virtually non-existent state, leaving in it's wake a dramatically reduced mentality, resulting in a complete inability to reason, analyze or interpret even the most minute of observations.
This severely compromises the individual's ability to gather the necessary material required in order to think critically or form sustainable hypotheses for future studies. Therefore, vacated is the right to compile data needed to form the eventual theory, also vacated is the ability to form a meer opinion on any given subject, despite the level of importance, or significance.
This is a great example of just how reduced the individual will inevitably become, after an incomprehensible regression into a single point, void of meaning, only capable of contributing impulsive linguistic patterns which are spewed into existence and onto the faces of the intellectual, sophisticated, scholarly noblemen.

@40:00 For those interested, the Helium "problem" refers to stars early in the age of the universe with only about 1/3 of the helium expected, helium being produced by fusion within stars of hydrogen. Measurements showed more carbon, nitrogen, and oxygen in the stars than expected, which leaves open this question of where did all the helium, one of the most abundant elements in the observable universe, come from? As this measurement of helium came from a small sample of stars it could simply be an anomaly, or if actually representative it could suggest that there was some kind of secondary fusion taking place outside of the stars converting hydrogen to helium. I'm not an expert but I believe that these days the more common belief is that how much of a particular element stars produce is based upon their characteristics like their mass.
JJ Thomson proved in 1913 he could get fusion of light elements in a tube. They weren't created in the Big Bang.

Made it very clear for someone seeing this for the first time or even anyone really struggling to understand
Quantum Physics is little hat nonsense designed for egg heads to fry their egos on.
I never liked the school.But I loved physics lectures.I left the school and now I am watching quantum physics and can easily understand.
Thank you, Sir!
If Quantum defies all logic, then it cant possibly be understood by logical scientists. If you can figure out Quantum "rules" then its not defying logic is it. BUt in reality Quantum is hocus pocus mysticism repackaged for the gullible idiots of today.
would the study of quantum synthetic vibrations be used to create low level electronic vibrations to generate artificial vibrations to Smellivision to enhance the modern television experience? It would be a massive undertaking but I think it would be possible given time to generate a library of electronic created synthetic scents to insert into images.😮😮😮

Physics doesn't break down at quantum levels, but our understanding of physics does.
My thoughts exactly, sounds extremely arrogant from such insignificant apes .
Yes we know… if they thought physics broke down at the quantum level they wouldn’t be doing experiments to try & figure it out. The reason he put ‘When physics breaks down’ instead of ‘When our understanding of physics breaks down’ as the title of the video was to keep it short & not have a long drawn out title. It’s not because he literally thinks physics won’t work beyond our understanding….
His honesty isn't good enough for you? You are right, of course. Our understanding (given materialistic assumptions about the nature of ALL reality) breaks down.
Case in point, Einstein said, "I'd like to think the moon is there when I'm not looking at it".
Einstein's intuition was correct. There is a deterministic aspect to reality that makes it objective to you and I. Our observations and measurements, however potent they are, do not define EVERYTHING.
But this does not mean that everything is determined mechanistically. Conscious agency can also determine and define (measure), according to purposes independent of material causality.
You are fooling many with your assurances (look at all those thumbs up). But not I.

Sir Al-Khalili l have only watched 3 of your documentaries Shock and awe the story of electricity , What is energy and now The science that defies all logic . Science for me serves as a source of fascination with your elegance in explaining concepts and introducing to me many other great scientist that contributed to the discoveries of scientific laws we now know to aswell as technology it is safe enough to say you have excited me even more and make me want to be apart of this great voyage to understand the observable and un-obsrvable universe but l shall take a path in EE as l am deeply interested in invention. L am currently doing the tenth grade and physics mathematics and chemistry are my favourite subjects as pondering on the concepts discovered in these subjects is what makes me a science enthusiast. Thank you and your team for putting your time to make such films .
I've seen all the laws broken here on Earth: time, motion, potential energy, kinetic energy, gravity, all of it. I watched time stop for all objects except me, same for gravity and motion. A clump of dirt flew in and was frozen in front of me. I also forgot that I was in the middle of a car accident and the car was in the air as well as we hit an embankment at 85 mph. All I cared about was what this thing was that flew in the car. It looked like dirt but dirt doesn't fly and stop. I had to scoot up to see it better. I still couldn't see it so I had to loosen my seatbelt to scoot all the way up. I put my eyeball right next to it and saw that it was a clump of dirt. Then I remembered about the car accident and had a quick panic attack. I checked my seatbelt and looked at my friend. His face was frozen just like the sand. I saw his seatbelt on, then boom. Time came back on. My friend didn't have it happen to him.
It was like pushing pause on our environment including my friend; pausing everything except me. I stayed in normal time, gravity still worked for me as I wasn't floating. The sand looked still floating in the air. I figure that it took about 15-20 seconds to scoot up, then again, then freak out, finally check our seatbelts. It wasn't an adrenalin rush like everyone says. I was completely calm and normal until I remembered what was happening and realized that time was stopped. Then I freaked out, but before that I was normal.
That is one of like 25 stories that happened to me. When I was ten years old, it happened in front of my parents. I was doing my homework and the phone started ringing. I looked at my dad and he didn't move at all. Looked at my mom, the same. I get up kind of upset nobody was getting the phone when I was trying to do my homework. My dad looked at me like WTF and my mom got up from the other conjoined room to see what I was talking about. When I got to the phone and was reaching for it, it rang for real. The two rings overlapped each other causing a much louder ring. I was instantly sick and going to faint, but my mom caught me by my cheeks and told me I had a gift of ESP. I slept for a day and a half. There's two. This life is an illusion, a simulation. I know that's hard to believe unless what happened to me happened to you, then after thinking about it for 30 years, you would have the same conclusion as I have had. It has to be a simulation. All of you are simulated.
Why am I writing this then if you already know that? I guess for the chance that someone may know how to get out of the simulation. The exit.....
I would love to interview you about your experiences
Sir, your explanations are WONDERFUL! I have always thought of reality as obeying laws that are sensible, but quantum physics gives the impression of not doing this. String theory attempts to make things a bit more sensible, but probably is not the answer. In any case, the way that you put real world explanations to these things is so very good.
Brain will not faster than natural evolution less than earthquake
String theory was hyped as the answer just a few years ago..... it solved so many problems. Alas, as one absolutely final theory to explain everything goes down the plughole, another one emerges which is next final theory to explain everything. What atheists need more than anything are theories.
@jk-video2716 much of the physical world follows logical laws that are comparatively easy to grasp. And our faith in the uniformity of nature (at least in terms of its being logical) is well founded as a result. But if a conscious observer is involved, in order to understand how more difficult problems are logical, we would have to comprehend the purposes of the observer. And that may not always be possible.

There is no reality to perceive without awareness of the perceiver percieving “reality”. As my father often said “reality is in the eyes’ 👀 of the observer. ❤❤❤

This is the third time I've seen this exact documentary, featuring Jim Al-Khalili, under a different name. I can't remember what the original production was, but the second time it was published under Spark. The fact that it's now showing up on this channel with none of the original production logos does indeed make this look like stolen intellectual property.
Jim Al-Khalili, I did my best to follow your excellent lecture explaining quantum mechanics in layman's terms. As try as I can, however, I still do not understand why it is that Bell's experiment showing sums less than or greater than two answers the question whether Planck or Einstein was right in explaining the uncertainty about entanglement and whether there is spooky action at a distance or some hidden variable that underlies and explains entanglement. Is there a chance you could explain why knowing the answer to be < or > 2 is outcome determinative?
Bell's Inequality.
Look up the wikipedia page. They go into the math. There's a *lot* of math. It's not that difficult, but it will take you some time and effort.
watched this couple yrs ago on bbc. Jim nails it again. Great bloke, excellent presenter, very very interesting. more please
This is just the explanation about quantum mechanics I was waiting for in years. Thank you for that Professor Al-Khalili. In my understanding Physics is aimed at associating models (numbers and equations) to the real things. Models are there to predict the result of future experiments, which then prove if they were right (aka: applicable) or wrong. So I have no problem if a (relatively) free standing electron, or a crashing electron on a detector follows the particle model, while a fast traveling electron fired by the gun follows the probabilistic wave model. What I miss in this case is a description of how properties of the electron are modified when it is "fired" (or: what makes it "evaporate" to a probabilistic wave). Similarly, how the electron properties are modified when it is "detected", "measured" or when the probabilistic wave "crashes" on some obstacle to crystallize again as a particle at a (somewhat predictable) random place in space. Studying these transitions could be more profitable than arguing on "which reality is real". Concerning entanglement, did someone look at it as two crystallization's of a single wave ? The video suggests that the second coin continues to turn when the first one is fixed. Isn't that misleading ? when the first one is "detected", what if the second one has been displaced out of reach of a detector ?
But what an admission to make, that" QM defies logic".. In other words, its not rational. In even more words, that means that it cant be studied by rational logic humans, who's only way of discovery is by applying the rules of logic together with a rational understanding. So maybe we should let patients on mental hospitals study QM? because they are irrational and illogical? And their thinking can not be understood by those that are rational and logical. But maybe scientists ought to reconsider their interpretation of those few observations that led up to the belief that there was a new science at work, namely QM. Its more likely that they are flat out wrong. But too pig headed to admit that they have been fools. Another bit of "science " that is irrational and illogical in everything that Einsteins said. Few people have realized this fact thought. Meantime is a great article of faith for the believers.
Applying Doyle's Law, if QM is right, then 'Logic' is wrong.

I think its very interesting that the electron produces the same pattern as a photon because it has charge. If we say that the electron is in a superposition before interacting with the detector, cancelling out in areas of desrructive interference, the question arises whether charge would play a roll. But it clearly doesnt. The wave function does not account for the particle's own charge, but the charge of other particles. How is this distinguished? And ill point out that photons can exist in the same exact state as bosons are exempt from the exclusion principle. So its not as if it is somehow bouncing off itself in a state of superposition. This is truly bizarre and unique.
This video was already shown on TH-cam about 5 years ago. Don't see how its suddenly only 5 days old?

Not getting bought it becomes minced meat getting a new date. Not getting bought it becomes sausages and a new date. Not getting bought it could become a part of a pre made dinner only needing a little heat to be eaten. Not getting sold it doesn't get a new date but a considerable discount. Someone is almost bound to buy it. Thinking it was only made yesterday - if I eat it today it will be safe and almost as good as new. It might very well be safe - it's just not "fresh" and started life earlier in another context. Essentially the same and legally only a few days old... Luckily the videos ages well without a sense of being outdated. If you missed it the first few times around - don't worry - it will find a way to you one way or the other....

Jim says that wonder is just how quickly the tadple turns into the frog and clearly this is true. But also, the wonder is just how slowly the same thing happens. During these weeks of transformation all states of the change must continue to be life-viable or it would die.

Nothing has fixed value. Everything is variable and ever changing.
The biggest problem with physics is observation and how a particle is coupled or not since our observations can only see what is in the past of what we are looking at......since light has a limit in vacuum it cannot travel faster than itself and there is always a length of time and distance that always is part of our calculations we can only view something as it was and not how it is from its own place in space time......we can never observe anything unless it from the past no matter how small the length of time which also means time would have to be infinite

For those who don't know, this is where Schrodinger's cat comes from. He and Einstein came up with it to show how silly "spooky action at a distance" really was.
I'd always heard that "spooky action at a distance" was how people thought of Newton's ideas about gravity, at first. After all, how could the Moon affect the Earth, and vice versa? But maybe I heard wrong? You never know.
@@Bill_Garthright I can't say you're wrong because I don't know for sure, but I just looked up "spooky action at a distance origins", and found references only to Albert Eintein having coined it. I also searched for any refernce to Newton in the phrase, but all I found was that Newton said that gravity caused "Action at a distance", with reference to the earth/moon attraction - but no indication that Newton thought it "spooky".
Incidentally (fun fact), Newton declared that he saw further, because he stood upon the shoulders of giants (a rare moment of humulity from what I can gather). When Einstein was asked by a reporter if he stood upon the shoulders of Isaac Newton, he replied "No. I stand upon the shoulders of James Klerk Maxwell". However, I did find an Einstein quote about Newton : ""Newton, forgive me," wrote Einstein; "you found the only way which, in your age, was just barely possible for a man with the highest powers of thought and creativity. The concepts which you created are guiding our thinking in physics even today..." And, of course, he used calculus - though Leibniz should probably get the credit for the calculus we use today.

Two questions come to mind watching this. First, what does 'the other particle simultaneously changes' actually mean in a relativistic universe? They are separated by an interval, so we can change the time and distance by switching inertial frames. Second, the robins. Assuming the electrons are entangled, how did that happen and still guarantee they ended up in the correct positions?

Time is fascinating. I worked the subway stations for nearly 10 years. From one end of the city to the other. Every so often I would notice the city would be saying that, "Today just flew by" or "The day was just dragging along." How can an entire city, with no interaction with each other until they used the subway, complain about the same time paradox unless it was effected by it? Maybe a time distorted bubble the earth passes through in its revolution around the sun. Maybe random waves of time distortion hitting the earth? Maybe they're given off by the sun. Maybe they're from outside our Terran system and reach us in intervals. ???? 🎶Ti-i-i-ime, is on my side. Yes, it is!🎶
If you can think of a better way to do a blind survey of an entire city, in the small window of opportunity, I'm all in. Until then, I invite you to spend a couple years in the subways. Between 2pm-10pm and you'll see for yourself. Just listen as an entire city gets off of work and gets out of school. You'll see it's more than a, "coincidence of circumstances."

Professor Al-Khalili is to Physics as Sir David Attenborough is to the Natural World and Lucy Worsley to History.
Knowing creates unknowing at the same time; they arise mutually.
I think we need to consider the ground radio-activity resulting in alpha-particles, near volcanos, and even in volcanic ashes that spread to long distances when we think about the mutations due to protons. This could also explain how billions of different species of different sizes and shapes were born to the world many millions of years ago when the ground radio-active levels were high due to thousands of volcanic eruptions. Of course then nature applied natural selection explained by Darwin.
Get quantum buddie there is only now the past and the future are both seas of potential.❤❤❤
Perhaps indeed we seem to have a most pre/post cataclysmic event history.
I loved the scene of club house set-up at minute 20:30, where Prof Al-Khalili 'time traveled' himself back into the year 1922 to explain on the light theory. Really nostalgic and classic moment.

Yes, a 3D reality, residing within a 4D space-time reality. Two radically different sets of laws of physics. Examine the 4D laws of physics from a mere 3D point of view, and things seem very bizarre indeed. Again and again, you will see the 2 slit light experiment being discussed or demonstrated, and how minor changes can determine whether you will end up with an interference pattern, or not. But never will they mention that these minor changes determine which set of laws of physics come into play. HOW ODD OF THEM ???

@@sgartistry1418 anything that can be proven is not God.
Anything involving faith and beliefs is involving a god or gods. Science isn't absolute either. You can study doing experiments making a theory plausible. There are many levels of scientific proof. It can relate to a very specific subject under specific circumstances. It could be applied in a wider context being a general law/theory but not being specific. In fact it could be any combination thereof. Theories are more often than not a working model applying the knowledge in a way that brings understanding - but not entirely correct. Engineering is science put to practical use... cutting corners - things have to be safe and working. You add a little here and there to ensure things are safe and working properly in a given interval of time.
Some scientist believe in God but see no conflict. As scientist they speak upon matters they can prove or make plausible. Religion is another dimension. Copernicus discovered the Heliocentric System. The sun being the middle of the Universe and everything else being in orbit around the sun. He himself was a devoted believer. He saw it as a form of worship understanding the inner workings of Gods creation. Adam and Eve took a bite of the Apple of Wisdom - why they were kicked out of Eden. Having knowledge they now had to use their intelligence to make a living. Just like young people graduating moving away from home. As far as I know most religions encourage getting knowledge (both sexes). All major religions have it including Islam. Traditions and cults derived from the original scripts may have other rules - but they're not found in the "original" religion/scripts. Adam and Eve were basically told to use their brains. People using religion to debunk science are just as wrong as people trying to debunk religion with science. To different systems you can't apply rules from one to the other. The simple saying of comparing apples to oranges. They're fundamentally different. You can't compare. The measuring sticks are different as well.
When some branch of knowledge breaks down is called ignorance. God is ignorance in disguise.
@@paxanimi3896we create God to our image. Your god is ignorant because of your own lapses.
The physical is only the tail end of an event that is originally a psychic event. An object is a solidified thought. An event is a motionized thought complex
Thank you for stating the obvious apparently not so obvious 😑
I wish we could have total world peace so we could focus on these questions
Physics never breaks down. Same for millions of years. People come and go. Have to learn the same thing over and over.
I love his wonder and joy. It’s so infectious
Ive soved Einsteins “Spooky Action” riddle. Space and Time are being pressed up into your face at the speed of Light then returning back instantaneously thus, resulting in the illusion of time. “ Time is but an illusion.”
This is absolutely amazing content... Thank you. Normally, I would be like yeah nope not for me. I actually enjoyed this...
Super great analysis, opening my mind to ideas never previously considered great program
As we start, as an electronics “dude” I can’t help but note that the light bulb as a vacuum tube lead to the first electric switch the vacuum tube! They knew about the transistor or diodes for yrears before they figured out how it worked. It was expected to create energy which I did not but led to switch controls witch inject power control by design. Based on this , we are half way through a next such tool.
One of the few people who look EXACTLY as their voice sounds. Thanks for the content
This documentary is oscar winner indeed! very beautiful
I am ignorant of sciences, but curious and always inquiring about some of the regular situations in my everyday routines. In this video, my doubts have increased, and I am more skeptical about whether I exist or if it is just being a part of something undefined, uncertain, and surreal. How knows!
Completely does my head in. But I love it!
Has anyone else noticed this 22:20? "But when I observe you, you change your behavior". Lol I love that clever peek into an important aspect of quantum physics.
What causes this aspect you speak of presumably
@@NarenLumpkinentanglement
In the end reality is a local phenomenon unique to each of us but as a whole universal to all of us through entanglement😮.
Well done Jim, my students (and I) enjoy your work, thanks...
I took the trouble to watch this video. Beautifully done. Thank you
The video is a treasure trove of information.
How do the experiments relating to the Earth’s magnetic field fare now that is so weak?❤❤❤
Space and time are relative obviously.❤❤❤
QM doesn't defy logic, it defies our normal understanding of matter. But our normal understanding of matter is merely a construct from our representation of the material world through our senses, which is itself at best an approximation of material behaviour at a much larger than quantum scale.
This stuff is so fascinating to me...I love to think about how everything we know and have discovered is from the human perspective and wonder what what diffrent things the really is and what else is out there that we will never know or understand. Because everything is from or point of view. Crazy if u really think about it. Would love to really know what everything really is and how it was made and where and why we are.
I was sweeping while listening to this and just in the fist min as I swished the broom and all the puff 💨 of dust traveled though the air I imagined the quantum world and what it would’ve been like to be in there and what it would be like. Good stuff, the weed of course👍
Very interesting, agree we need more, TH-cam should follow this type of program more
Keyword, "Professor". The one who professes (to the layman public). There is a section in professorship applications about public outreach. For most of us scientists, this section is left blank. Really! Scientists are mainly really bad at public outreach. We just do our research hoping no one in the public ever asks what we do for a living, partly out of fear of trying to explain. Jim Al-Khalili amazes me. He does excellent science and also does excellent public outreach. Must be an alien. :)
We did public outreach about quantum mechanics in high school science class. Did you forget all of that, already? ;-)
If you ever wonder about the existence of the physical world when you aren’t looking at it, try falling asleep at the wheel during rush hour.
All part of the illusion.
Love your videos and how you explain. Really makes one think…
It would seem that if you needed to hit a target that using a large wave might not do any better, it might have more energy, but it might also miss the target all together.
If we put a car on a race track and we tried to send someone across the track, when the track is long it is easier to avoid a collision.
As the track gets smaller and the loops occur more frequently it gets harder and harder to make the crossing while avoiding a collision. At a certain frequency, it becomes almost impossible to make the crossing without a collision occurring.
Yes we could increase the mass of the race car, but if it doesn’t result in a collision, the additional mass doesn’t have a meaningful effect.
However even using a tiny car that is moving fast enough we can almost guarantee a collision will occur.
The larger question, is does Increasing the intensity ever result in an expelled electron? While it might be unlikely to produce a collision at slower speeds, it might still occur infrequently. Similar to a neutrino hitting a nucleus of an atom of water.
Does the photoelectric effect ever appear to spontaneously happen? It would seem like if the waves are going too slow, it would happen very infrequently if ever.
But it seems that using a bigger wave is akin to adding more mass, while using higher frequencies is akin to increasing velocity. And 1/2*m*v^2 would mean adding velocity is more effective means of increasing energy.
Brilliant program very informative but at s simple level
Great explanations... still, mind blown :)
I wonder if quantum tunneling is akin to a reflection of the strong and weak nuclear forces?❤❤❤
I LOVE this content. It not only helps me sleep but I feel like I am learning something. Science. It works bitches. Otherwise imagine having to live by moonlight at night and communicating by banging on logs. Which is about as advanced as us hairless apes would be without science. Embrace the truth or what most likely is and hang on for the ride. It is spectacular.
Know thyself fools’.
