Clearly a Dunning-Kruger example. As a physicist I can assure viewers that the formula for kinetic energy and its relationship to gravitational potential energy is solidly understood by everyone who takes the time to do a few experiments with rising and falling objects in a gravity field. And the person who usually gets credit for recognizing the key facts about kinetic energy is Émilie du Châtelet. She figured this out dropping cannonballs from various heights into mud to judge the relative energy by the sizes of the craters in the 1730s. Being a woman at a time when men thought they were the only ones who could do science, she had to publish her findings through a man who presented the ideas as his own.
Very interesting. As someone who is not a physicist, I at least understand enough to realize when science makes a mistake, as has happened we all know, it self corrects pretty quick since everything that follows, based on that mistake, fails. Anyone that thinks a scientific discipline can progress when it is built upon an incorrect base is literally an idiot.

@@IndictEvolution religion is dogmatic, science is skeptical, dogma and religion has all the answers already, science and skepticism is trying to find better answer, new answers, improved answers.
At work 30-plus years ago I supported a waterjet cutting machine. It used a very high pressure stream of water and grit (from corncobs as I recall) to cut aircraft parts. To catch the stream there was a small cup filled with out of tolerance stainless steel ball bearings (much cheaper than the in-spec ones!). A drain from that cup carried away a slurry of water and steel particles. I realize that is rather different than moving water in a stream, but then the waterjet cutter is optimized to work almost instantly, while flowing water and random particulates takes years or more.
Water is made up of tiny molecules and when water is flowing those tiny molecules strike against equally tiny imperfections in rock causing them to slowly break away in microscopic pieces over very long periods of time. The process of tumbling a rock in a tumble accelerates this process through using various sizes of grit in water to simulate being in an environment of flowing water over a long period of time in a vastly shorter period of time. Think hundreds or thousands of years taken down to days. In either case the flowing water is used to carry away the broken off material. Tumbling is not a rock falling down a mountain, it's closer to sanding out the rough edges of a material and the tumbler's effectiveness comes from the constant flow of water and grit moving over every part of the rocks inside the tumbler as the rotating drum allows them to be constantly repositioned to allow other sides to experience the flow of material.
Lao Tzu recognized this over 2500 years ago when he said, "In nature, the softest thing in the universe (water) overcomes the hardest thing in the universe (rock)."
This guy is a complete crank, he's been arguing the same "ideas" on physics forums for YEARS, he's been proven wrong every single time, he's rebuttal is always the same, basically, na uh.
I think this guy is the same crank who used to go by the name 'inmendham'. I really hope he's not "in" Mendham, NJ because I live near there and I'm afraid his ridiculous "theories" will pollute the air that I breathe. One example of his contributions to physics is his theory of the electron. I forget the details but basically he says that an electron is a shell that contains several photons which are released at appropriate moments. Ugh! He used to be quite prolific on TH-cam with his theories of just about everything that strikes his fancy.
His physics may not be his best work, I'm not in a position to judge but his takes on philosophy in general is sound, he is def not some dumb wack, his videos on economics is good. Been watching him on and off for over a decade. He's an interesting character for sure.
@@ReinoGoo I have to confess that he confused me enough to misunderstand what he actually said. Yes, when falling double the distance the velocity isn't going to double as the 2nd half of the distance is passed in a shorter amount of time due to acceleration. Time for another self-facepalm.
I reacted similarly, it was something in the way he presented it that made it seem like a crock'o'shyte. Maybe I interpred as constant energy supplied needed to keep a vehicle at comparative speeds. So, doing a generous interpretation he meant just the kinetic energy stored in an object, or the external energy needed to push a mass up to speed (disregarding air and mech. / frictional losses)
A lot of white sand comes from parrotfish crap. They eat coral and the coral skeleton is indigestible, so they poop it out and it comes out pulverized. I thought that was gross and fascinating when I learned it.
Bogs are actually sometimes acidic and if a stone is left in a bog it will be eaten slowly into powder . Thusly a bog can change the shape of a stone .
10:14 I know this is super niche and tangential at best as Dan's pronunciation of "Leibniz" is fine the way it is, albeit anglicised, which has its benefits. Anyone who wants to get closer to the original German pronunciation, can try turning "Leeb-knits" into "Leyeb-knits" like this: The beginning sounds very much like "lie" (as in "flat earth is a lie"-bknits) and then transitions into "bniz" via "eib", which is close to the "eyeb" in "eyebrow." Dan's "knits" was solid already. The stress is on the "eye" and a very subtle pause is between "Leyeb" and "knits," which he does very well, too. tl;dr: Try going from "eyebrow" to "Leyebrow" to "Leyeb-row" and finally "Leyeb-knits."
Flowing water alone is definitely enough to carve rocks. I have tons of "transitional rocks", half smooth, half rough..like what? When I was actively looking for fossils, after hours of focusing hard, my brain started seeing patterns where there were none, that's a sign to let your eyes relax and do something else, not go on for decades and become a dude who has "fossilized testicles"..
the climb in Yosemite called "The Shining" is a cascading waterfall in the spring and summer and dries up in the fall. It is smooth as a mirror, hence the name. No tumbling needed, just water, and this is granite
granite is a very hard rock and will polish very nicely. if that climb was over sandstone it would not be called the shining as sandstone will not polish nearly as well
@@dom11949 you are correct. The point was that it gets smoothed out with nothing but water, where this guy says it needs to be tumbled with other rocks or sand to get polished
@@chriswatson7965 My high pressure washer at home begs to differ. It certainly cuts into my wooden deck if I have the nozzle on its smallest setting, and chips away at the edges of concrete too. Having an abrasive in the stream is certainly more time efficient, and allows you to cut harder substances, but water on its own is still capable of cutting/eroding.
@@h14hc124 Pure water jet cutters exist but use the velocity of the water to break the integrity of the substance that they are cutting. It is not a case of them being quicker. If the stone is insoluble, there are no abrasives in the water, and the water velocity is too low then the rock will never be cut no matter how long you spray it (ignoring spontaneous breakdown of the material in the stone due to quantum effects). The principle behind the workings of pure water jet cutters has no bearing on the reason why we get round stones in streams.
Okay, so we see a narcissist make a ridiculous comment video over what he himself thinks is a ridiculous comment video? How ironic is that? Well, it gave me a good laugh. Thank you SciManDan for another fun start to the Tuesday!

I would freaking love a good old style debate between him and Dan, i want to see that old Inmendham when he used to rage in anger, i even joined a few of his livecams during the debate days, it was freaking glorious.
I think the issue here is (apart from Draft Science being confidently incorrect) is that us Brits sound naturally sarcastic and like we're taking the mickey ALL the time, which in fairness we only do MOST of the time.
Unit of work/unit of energy- in everyday vernacular, what's the difference? I understand the distinction, but just for a video's purpose, it seemed adequate. I'm genuinely curious, as I'm a layperson.
Yes if watt is unit for energy, Joule is the unit for distance. Another engineer here. He is completely scientifically illiterate. Often mixup of units can be a tell for illiteracy. He changed v(velocity) for s(distance) too in the kinetic energy equation mv^2/2. (I am Swedish, perhaps you don't use s for distance).
10:09 "Yes, that's all fine!" Well, technically, he's already gone wrong here too. I think you missed the fact that he's referring to energy in "watts", which suggests he doesn't even understand the difference between the concepts of energy vs. power.
Most of the erosion in the Grand Canyon is done by a combination of the water dissolving some substances, abrasion by the harder materials in the flow, and weakening of the walls of the canyon through exposure to temperature variation. Pure erosion by water alone plays a very small part.
If I was being generous, I would say that Howard meant that the tiny hard particles being carried in the flow of water were responsible for the erosion, but of course water is a great solvent, so anything that dissolves in water would be carved out in pure flowing water, and some particularly soft rocks would start to dissolve even while sitting in still, pure, water.
@@Hexon66 Yes and no. If you have pure water flowing over an insoluble rock there will never be any erosion, smoothing or rounding, ever. This was in essence the claim that Draft was making. However in practice there is no such thing as pure water in a stream, and many rocks are mildly soluble. So running water in a practical situation will cause erosion. This is the splitting hairs element that I think that you are referring to. But I don't think that it is splitting hairs to point out that the example provided by the OP does not support Dan's point of view, not at least without some context. IMO it's either not understanding the argument, or not understanding the underlying physics.

As a caver I can telll every one. Water is damn abrasive.. Half the passage ways etc we follow are active or old stream ways that over time due to water flow have enlarged and still enlarging due to the water cutting is way through the rock......
Is it the water itself or the suspended sediment in the water that abrades the rock? If there were no sediment I suspect the cutting action would be greatly reduced. That said, water with dissolved carbon dioxide can chemically dissolve limestone, which is another way in which caves are formed.

When I was at school, we tested the kinetic energy formula, the gravitational potential energy formula and Newton's Law of Motion experimentally. They probably do the same in most other countries - it's really not difficult and doesn't take any sophisticated equipment - a ball, a piece of string, a plank of wood, a tape measure, etc. That quickly gets rid of any personal incredulity. If only these science deniers and flerfers would try this stuff themselves.
They skipped that "nerdy" stuff in school and most of them avoided science like the plague. I run into the same thing in my own family with a gigantic "nuh uh" when I try to explain anything to them.

The principle in classical mechanics that E ∝ mv2 was first developed by Gottfried Leibniz and Johann Bernoulli. The Second Law of Motion is, of course, Newton.
Aspects of the concept of work done appear as early as 60AD in the writings of Hero of Alexandria. Hero reported that if a weight were raised with a pulley system by the exertion of a force less than the weight being lifted, the rope must be pulled with a speed greater than the speed with which the weight rises. Leibniz used the law of falling bodies to argue that the object with mass m reaches double the velocity of the 4m object, because it falls four times the distance. As the same ‘force’ is required to lift both bodies, the value of version of kinetic energy (he called it vis viva) should be related to mv^2 not mv as had been suggested by Descartes around 1664. Moreover, Leibniz (1686) argued that the quantity mass multiplied by velocity squared was conserved. The disagreement between followers of Leibniz and Descartes over the nature of vis viva occupied philosophers for over 50 years. English and French thinkers tended to favour the notion that ‘living force’ was represented by mv, with Dutch, German and Italian philosophers preferring Leibniz’s mv^2 construction. It is argued that Newton understood, and used mathematically, the concepts of the kinetic and potential energy in the context of objects in orbit (1687), without having explicit terminology for the concepts. A significant contribution to the debate about the nature of the concept of energy was made by Émilie du Châtelet, a female French philosopher and scientist born in 1706. She proposed a thought experiment in which a spring projects a ball forwards on the deck of a boat. She pointed out that James Jurin (who argued in support of Descartes) and others had neglected the recoiling motion of the boat. She asserted that the model of ‘force’ as mv, which had been supported from this mistaken assumption, should be replaced with the quantity 1/2mv 2 and *_proposed the conservation of total energy in addition to conservation of total momentum._* Some historians of science argue that the vis viva debate was finally resolved by Jean Le Rond d’Alembert in 1743. He pointed out that the controversy was “un dispute de mots”, a dispute over words, rather than a disagreement of physical models. He showed that it was possible to use both conservation of mv and mv^2 in the same system. In 1807, Thomas Young was the first person to use the modern sense of the word ‘energy’ for the quantity of mass multiplied by velocity squared. William Thompson, who later became Lord Kelvin, is credited with introducing the concept of kinetic energy in 1849. We now associate the concept of an object’s kinetic energy with the quantity of one half of its mass multiplied by its velocity squared.
I think this might be the first time that a major science channel (at least in the hundreds of thousands in terms of subscribers, let's say) has played a video or clips of videos from DraftScience. I am noting this because he has, I believe, been requesting for some years that such a channel do this. An 'historic' moment, in a sense.
Hahaaa. When I was in school the teacher had a metal box and a two lengths of string. One length had metal nuts at equal distances tied into the string. Then the teacher held that string extended and dropped it into the metal box. Guess what, the clanging of the nuts hitting the box sped up, the nuts were hitting the box at an increasing speed. The another length of string also had metal nuts tied in -- but at an increasing distance, increasing by a factor of 4. Guess what the clanging did when those nuts hit the box: the clanging did not speed up or slow down, so the nuts were hitting the box at a constant speed.

That guy's fiddling on the whiteboard at the end can be answered by the first few minutes of the first episode of the great series _The Mechanical Universe_ , which is available to view for free on its web page which can be found on its Wikipedia page. "It's twice the time, it's twice the velocity, what makes you think it's 4 times the energy?" Calculus. In fact, there was a huge debate of mv vs. mv², and it was demonstrated physically by dropping dense balls onto pieces of clay and noticing the size of the resulting dents. That history is well worth learning! Today you might use an _instrument_ that registers energy deposited, but that works by integrating force over time; that is, by applying the relation you're trying to validate or refute.

Water can rip 6 inch steel plate off a boat, so it 100 percent can erode rock. Moving water is very powerful and the faster it moves the more powerful it is.
The only place you'll get "water alone" is in a laboratory with highly purified water. In practice, water is full of suspended bits of hard stuff (mostly bits of rock). Even "crystal clear" water, like in Quintana Roo, Mexico or Abaco, Bahamas caves, is full of stuff. "Clear" tap water has lots of suspended stuff. As said elsewhere, water molecules can knock molecules off rock, but the major erosional effect of moving water is from the suspended hard stuff.

Hi Scimandan. This is a rant about the idea that "scientists don't want to debate about science. " Of course not. Someone who falls for that doesn't understand either science OR debating. If you debate someone on ANY topic and win, it proves nothing about the topic. The ONLY thing it proves is that you are better at debating. If you are debating against science and win, you only prove you are a better debater. The debate proves NOTHING about science. Anyone who falls for that and thinks you proved science wrong just doesn't understand this point. People, please don't fall for this trap. A Public Service Announcement
The problem with conspiracists is that they thrive on any attention generated by debunking content. By challenging you directly, they're trying to piggyback on your views count. Remember that you are the size of your enemy and you should probably not give guys like these the time of your day..

“Water is not abrasive”
Ever heard of a water jet?
Water is defacto one of the most aggressive liquids known to humanity.
I just have to look at the paving stones beneath the edge of our terrass roof. Previous owner didn't bother to add a rain gutter, we added one, but you can still see exactly where the rain water dropped down all those prior years.

Aw, that's cute.
Hey that's Groppler Zorn. I've always wondered what he is up to since the Federation decided not to use Farpoint Station.
At work 30-plus years ago I supported a waterjet cutting machine. It used a very high pressure stream of water and grit (from corncobs as I recall) to cut aircraft parts. To catch the stream there was a small cup filled with out of tolerance stainless steel ball bearings (much cheaper than the in-spec ones!). A drain from that cup carried away a slurry of water and steel particles.
I realize that is rather different than moving water in a stream, but then the waterjet cutter is optimized to work almost instantly, while flowing water and random particulates takes years or more.
The principle is still the same, so I think your analogy works
Water is made up of tiny molecules and when water is flowing those tiny molecules strike against equally tiny imperfections in rock causing them to slowly break away in microscopic pieces over very long periods of time. The process of tumbling a rock in a tumble accelerates this process through using various sizes of grit in water to simulate being in an environment of flowing water over a long period of time in a vastly shorter period of time. Think hundreds or thousands of years taken down to days. In either case the flowing water is used to carry away the broken off material. Tumbling is not a rock falling down a mountain, it's closer to sanding out the rough edges of a material and the tumbler's effectiveness comes from the constant flow of water and grit moving over every part of the rocks inside the tumbler as the rotating drum allows them to be constantly repositioned to allow other sides to experience the flow of material.
Lao Tzu recognized this over 2500 years ago when he said, "In nature, the softest thing in the universe (water) overcomes the hardest thing in the universe (rock)."
Another way water can destroy rock is through explansion when freezing.

"Four times higher to double the velocity" ???

It means constant acceleration, and four times the energy.
@@ReinoGoo I have to confess that he confused me enough to misunderstand what he actually said.
Yes, when falling double the distance the velocity isn't going to double as the 2nd half of the distance is passed in a shorter amount of time due to acceleration.

I reacted similarly, it was something in the way he presented it that made it seem like a crock'o'shyte. Maybe I interpred as constant energy supplied needed to keep a vehicle at comparative speeds. So, doing a generous interpretation he meant just the kinetic energy stored in an object, or the external energy needed to push a mass up to speed (disregarding air and mech. / frictional losses)

10:14 I know this is super niche and tangential at best as Dan's pronunciation of "Leibniz" is fine the way it is, albeit anglicised, which has its benefits.
Anyone who wants to get closer to the original German pronunciation, can try turning "Leeb-knits" into "Leyeb-knits" like this: The beginning sounds very much like "lie" (as in "flat earth is a lie"-bknits) and then transitions into "bniz" via "eib", which is close to the "eyeb" in "eyebrow." Dan's "knits" was solid already. The stress is on the "eye" and a very subtle pause is between "Leyeb" and "knits," which he does very well, too.
tl;dr: Try going from "eyebrow" to "Leyebrow" to "Leyeb-row" and finally "Leyeb-knits."

@@h14hc124 Pure water jet cutters exist but use the velocity of the water to break the integrity of the substance that they are cutting. It is not a case of them being quicker. If the stone is insoluble, there are no abrasives in the water, and the water velocity is too low then the rock will never be cut no matter how long you spray it (ignoring spontaneous breakdown of the material in the stone due to quantum effects).

Water can't abrase stone, Howard?
Uh....How about The Grand Canyon?
Does that work for you?
Most of the erosion in the Grand Canyon is done by a combination of the water dissolving some substances, abrasion by the harder materials in the flow, and weakening of the walls of the canyon through exposure to temperature variation. Pure erosion by water alone plays a very small part.
If I was being generous, I would say that Howard meant that the tiny hard particles being carried in the flow of water were responsible for the erosion, but of course water is a great solvent, so anything that dissolves in water would be carved out in pure flowing water, and some particularly soft rocks would start to dissolve even while sitting in still, pure, water.
@@chriswatson7965 I'd say that's a considerable splitting of hairs, there. At least with the "harder materials in the flow" part. 'The flow'.
@@Hexon66 Yes and no. If you have pure water flowing over an insoluble rock there will never be any erosion, smoothing or rounding, ever. This was in essence the claim that Draft was making. However in practice there is no such thing as pure water in a stream, and many rocks are mildly soluble. So running water in a practical situation will cause erosion. This is the splitting hairs element that I think that you are referring to. But I don't think that it is splitting hairs to point out that the example provided by the OP does not support Dan's point of view, not at least without some context. IMO it's either not understanding the argument, or not understanding the underlying physics.

The principle in classical mechanics that E ∝ mv2 was first developed by Gottfried Leibniz and Johann Bernoulli. The Second Law of Motion is, of course, Newton.
Aspects of the concept of work done appear as early as 60AD in the writings of Hero of Alexandria. Hero reported that if a weight were raised with a pulley system by the exertion of a force less than the weight being lifted, the rope must be pulled with a speed greater than the speed with which the weight rises.
Leibniz used the law of falling bodies to argue that the object with mass m reaches double the velocity of the 4m object, because it falls four times the distance. As the same ‘force’ is required to lift both bodies, the value of version of kinetic energy (he called it vis viva) should be related to mv^2 not mv as had been suggested by Descartes around 1664. Moreover, Leibniz (1686) argued that the quantity mass multiplied by velocity squared was conserved.
The disagreement between followers of Leibniz and Descartes over the nature of vis viva occupied philosophers for over 50 years. English and French thinkers tended to favour the notion that ‘living force’ was represented by mv, with Dutch, German and Italian philosophers preferring Leibniz’s mv^2 construction.
It is argued that Newton understood, and used mathematically, the concepts of the kinetic and potential energy in the context of objects in orbit (1687), without having explicit terminology for the concepts.
A significant contribution to the debate about the nature of the concept of energy was made by Émilie du Châtelet, a female French philosopher and scientist born in 1706. She proposed a thought experiment in which a spring projects a ball forwards on the deck of a boat. She pointed out that James Jurin (who argued in support of Descartes) and others had neglected the recoiling motion of the boat. She asserted that the model of ‘force’ as mv, which had been supported from this mistaken assumption, should be replaced with the quantity 1/2mv 2 and *_proposed the conservation of total energy in addition to conservation of total momentum._*
Some historians of science argue that the vis viva debate was finally resolved by Jean Le Rond d’Alembert in 1743. He pointed out that the controversy was “un dispute de mots”, a dispute over words, rather than a disagreement of physical models. He showed that it was possible to use both conservation of mv and mv^2 in the same system.
In 1807, Thomas Young was the first person to use the modern sense of the word ‘energy’ for the quantity of mass multiplied by velocity squared. William Thompson, who later became Lord Kelvin, is credited with introducing the concept of kinetic energy in 1849. We now associate the concept of an object’s kinetic energy with the quantity of one half of its mass multiplied by its velocity squared.
He's just a more offensive version of Terrance Howard.
Needs a scientific explanation of what happens, when you skip breakfast and go straight for the bong...
That guy must be a riot at parties!
Liebnitz is credited with coming up with the mv2 value for kinetic energy.

Hahaaa. When I was in school the teacher had a metal box and a two lengths of string. One length had metal nuts at equal distances tied into the string. Then the teacher held that string extended and dropped it into the metal box. Guess what, the clanging of the nuts hitting the box sped up, the nuts were hitting the box at an increasing speed. The another length of string also had metal nuts tied in -- but at an increasing distance, increasing by a factor of 4. Guess what the clanging did when those nuts hit the box: the clanging did not speed up or slow down, so the nuts were hitting the box at a constant speed.

"It's twice the time, it's twice the velocity, what makes you think it's 4 times the energy?"
Calculus.
In fact, there was a huge debate of mv vs. mv², and it was demonstrated physically by dropping dense balls onto pieces of clay and noticing the size of the resulting dents. That history is well worth learning! Today you might use an _instrument_ that registers energy deposited, but that works by integrating force over time; that is, by applying the relation you're trying to validate or refute.

WTF!? Never heard of him, but visited his channel now. The guy has posted 4 thousand videos! Now that's a useless body of work.
@@fabrislemos 4000 on that channel. He has others. Or had others.
Has he ever done a collaboration with Santos - just asking for a friend?
@petertaysum8947 he's not a flerfer. He's an antinatalist who thinks that all life should not exist. He created his own... philosophy... called efilism. He had a few miserable bastards in his orbit which acted as an echo chamber and fueled his narcissism.
If he doesn't understand 4X then maybe he should double the top speed of his car with anything less than 4X and prove all science wrong.
Inmendham is TH-cam 1.0. OG. He was around when TheAmazingAtheist was big. He’s never changed I see, just an old bitter hermit.
One of my favorites of his videos was his cooking video: th-cam.com/video/KGf4U61x5Iw/w-d-xo.html
Water can rip 6 inch steel plate off a boat, so it 100 percent can erode rock. Moving water is very powerful and the faster it moves the more powerful it is.
You just have to look at underwater caves you can see how the stone is formed by just water alone
The only place you'll get "water alone" is in a laboratory with highly purified water. In practice, water is full of suspended bits of hard stuff (mostly bits of rock). Even "crystal clear" water, like in Quintana Roo, Mexico or Abaco, Bahamas caves, is full of stuff. "Clear" tap water has lots of suspended stuff.
As said elsewhere, water molecules can knock molecules off rock, but the major erosional effect of moving water is from the suspended hard stuff.
Triple H has never been the same since his crack and ketamine addiction, but can you blame him? Clearly the rock haunts him still to this day.
"who cares about this video?" Says the guy who recorded, edited, then published a response video of a response video of the original video.
I saw Gary in the thumbnail and was like what??? Lol
I think it would be amazing if you made some videos about HOW you learn about these scientific facts. Explain how and what you can trust and about how scientists are TRYING to disprove each other in order to further understanding.
Seems pretty self-explanatory- anytime you run across something you haven't heard of or don't understand, look it up. It's nerdy, but it's a great way to expand your knowlege. I've found myself wandering down many a encyclopedia rabbithole.
@@Deletirium No no haha. I want someone like Dan to show people who don't understand. I think most people who are distrustful of science just simply don't understand the scientific process. It is good for us to equip as many people as possible with the ability to understand science so they can use it too instead of just trusting what other people say.
You mean.. have Dan explain the scientific process, for the benefit of those who don't understand it ?
@@h14hc124 I think it would be amazing for people to see Dan explain how he researches things; what and when to trust and how to verify; how the scientific community works and how scientists are constantly checking each other's work to improve our understanding. I think a lot of people believe it is a religion or that religion is a science.
@@sub0fathom Dan is a science communicator, not a professional scientist, but I suppose he could walk people through the process that actual scientists follow. Essentially it's one of skepticism, where you don't trust anything, including yourself, unless you can back it up with evidence, and demonstrate why that evidence is valid and was collected/obtained correctly, with any potential biases or data contamination accounted for. Scientists do not just make stuff up and publish their findings for fun.
"There's no evidence for dragons."
Komodo and Bearded Dragons 😔
Wow.. that was a flashback to 10-14 yrs ago! He made videos under name "Inmendham" when the youtube christians VS atheists wars was the rage. He was quite a disagreeable character, by most atheists too.
" This isn`t worth my time" but continues wasting his time anyway !
oh well , it`s his time to waste, seems he has nothing better to do ! 😄
Unlike SciManDan I do have an issue at 9:55.
The unit of Energy is Joule, the unit of Power is Joule/second or Watt.
This guy confuses Energy and Power. This guy laughes at people for not understanding physics and not understanding the difference between Energy and Power is quite hilarious actually. I feel you could have pointed that one out, @SciManDan.
Cheers!
Most people confuse energy and power. Particularly journalists and TV presenters who deal with engineering and science.
Not a soggy biscuit! 😂😂😂😂
You stopped just as he went all Terrance Howard on us.
dunno, dont see this being worth a video, neither from him, nor from you. he might be a nutcase from his final segment which you then cut off, but at least he understands the theories and applies them correctly. also clowned on the stone guy pretty good
5:51 Yes, it's funny and people like Mudfossil University and flat earthers exist.
A hob nob laughs in the face of liquid!
DIP ME AGAIN!
AND AGA... oh, bugger.
@@PeerAdder😂😂😂😂😂😂😂
Hi Scimandan.
This is a rant about the idea that "scientists don't want to debate about science. "
Of course not.
Someone who falls for that doesn't understand either science OR debating.
If you debate someone on ANY topic and win, it proves nothing about the topic. The ONLY thing it proves is that you are better at debating.
If you are debating against science and win, you only prove you are a better debater. The debate proves NOTHING about science.
Anyone who falls for that and thinks you proved science wrong just doesn't understand this point.
People, please don't fall for this trap.
A Public Service Announcement
The problem with conspiracists is that they thrive on any attention generated by debunking content. By challenging you directly, they're trying to piggyback on your views count. Remember that you are the size of your enemy and you should probably not give guys like these the time of your day..
It's such a difficult thing...I kinda like what Professor Dave does: prevention work by putting out easy to understand science content and a takedown from time to time.
But especially concerning the content on this channel I totally agree with you
That DaftPhysics guy...sorry...DraftPhysics...is powered by personal incredulity. All he was saying was, you tell me it's twice the time? How can it be four times the energy? With the implication, I can't understand it, therefore, it's wrong.
So to be clear, I’m watching a response video to a response video to a response video..
Like Russian nesting dollls.
Thanks for your response.
Man, this Draft Science guy gives off "I carpeted my bathroom" vibes
I've seen him clean his fridge once.
Wet biscuits can be quite the thing when dipped into coffee.
Now we need the original video's creator to comment on you, commenting on this guy, commenting on you, and we will go back in time! Great stuff as usual SciMan. Loving the running channel also!
