Having higher framerate simply dilutes the effects from luck and your true skills start to matter more. Of course, the same applies for overall latency (ping + input latency + output latency).
Who would've thought, right? Hindsight is 20/20. I guess the problem was about not having a bright and compact enough lightsource to be carried by a plane. And that's where his invention comes into play.
It has a bonus effect that wasn't noticed/commented on. If the gunner had an idea where the plane was, putting his sights on target, the flash would momentarily "blind" him. protecting the plane.
very few molecules are fast, bright, stable, and predictable under extreme radiation induced oxidation. it's also a 1-electron induced oxidation which is handy in this case. it's also a precursor for the pharmaceutical molecule acetaminophen aka Tylenol aka Panadol
8:39 imagine being a German troop at Normandy on night patrol and then it’s suddenly daytime for a fraction of a second. Wake up in the morning there’s landing crafts outside
from the ground I wouldn't be surprised if it just looked like a small camera flash going off at a distance, among the stars, I doubt it's actually like the whole field being lit up
Oh wow, I thought I was the only one who immediately thought the same. I have a 101 unfinished projects here and another 101 which weren't the original goal and are--oftentimes--also unfinished. But, no worries! Because over multiple decades I also have at least 11 thoroughly finished projects, of which at least 3(*) stayed true to the original goal! (*) Might be 2. It's at least 1 I'm sure
I spoke with Dr. Edgerton around 1988. In 1987, he published a book, “Stopping Time: The Photographs of Harold Edgerton”. I was captivated by a particular photo of an atomic bomb explosion, captured with his Rapatronic camera. I wanted to buy an original print. As this was long before the Internet, I called Directory Assistance for the Boston area and there was a “Harold Edgerton” who lived in Cambridge. “I’ll try that one,” I told the operator. His wife answered the phone. After confirming this was the “Dr. Edgerton of MIT,” she hollered for Harold, who-long retired-was gardening out back. I spoke with him for about five minutes. Not until many years later did the significance of the man become apparent to me.
You sir were really lucky. I wasn't born at that time. Was born two years later your conversation. But every time I use Strobe i think of him and I have shot commercials at 20000 fps.
@tuomasronnberg I did not. He didn’t own the rights. He told me to contact the Department of Energy. This was nine years before Netscape Explorer, so the only recourses back in the Stone Ages were either to write the DOE or buy the book (mine was from the library) and cut it up. Of course, today, all one has to do is find a nice, high-resolution image on the Internet and print the thing. Do a Google search on *Tumbler Snapper rope tricks* Wicked photo.
As a VFX artist this is funny to see, they're basically running a raytracing renderer in real life, shooting camera rays and sampling surfaces multiple times
The guv at 26:11 - I have never loved any job NEARLY as much as this guy loves his job. His energy is great and he is SUPER excited to explain what is going on. That man is just happy to work there and that's awesome to see.
@richardrichter2285 More like Leonard. Sheldon was a theoretical physicist and thought that experimental physicists were an inferior species. Slightly above engineers who wasted their time on chananigans. Once Sheldon thought to have a brain tumor he was afraid that if the neurophysician could slip and he turns out to be like Wolowitz. Remember? Hilarious episode.
Totally agree. People like that should be role models for all of us. That being said, the pitch of his voice kind of, uh, startled me a little when I first heard it.
An attosecond is to a second As second is to the age of the universe The age of the universe is 13.8 billions year old... I can not begin to fathom this thought
@prinlerdsri405 A fact so astoundingly spectacular that I almost want to revisit weed just to get high and embrace the absurdity of it all in all of it's splendour.
I visited the LCLS at SLAC several times, to install and optimize the ultrafast (Femtoseconds, or Picoseconds) drive laser. The drive laser would fire a high energy pulse of Ultraviolet light at the surface of a copper plate. The plate then releases a burst of electrons, which is where the Veritasium explanation picks up, as those electrons enter the undulator. I used to give talks about ultrafast lasers, and to give a sense of the Femtosecond, I would say "Imagine that 1/10th of a second, or a blink of an eye, is stretched to one second. If that second is stretched proportionally, it would be 10 seconds, which would be a competitive time to run the 50 yard dash. Now, take a Femtosecond and stretch it to one second. That second would be stretched to 38 million years, which is roughly how long it took the modern horse to evolve from Eohippus."
29:08 HEY! That’s my friend in the background! She’s a PhD student working in SLAC. It’s awesome that she made it into a veritasium video. What she does is so freaking cool (stuff I couldn’t comprehend). If you ever read this, I am excited to see you carry the title Doctor. I know you’ll make some revolutionary discoveries!
Nothing can go faster than light? Pfft hold my physics real quick.... I mean it's true nothing IS faster than light If you're referring to an event horizon or something
watched this last night instead of studding for my physics exam and strobe lights literally came up out of the blue. I had no idea about them before this video (Edit- i failed the exam)
*"What If You Keep Slowing Down?"* I clicked on this assuming a thought experiment about a human experiencing time around them moving faster and faster around themselves. I am not disappointed.
If you are traveling on I80 in Nebraska, stop in Edgerton's home town of Aurora. It is home of the Edgerton Explore it Center, with several of his photos and information about his life. Our kids love the wide variety of hands on activities there.
7:20 "once Edgerton showed the world how powerful strobe photography was, he attracted some unexpected attention" Is it really unexpected at this point that people try to use every single particle of technological progress to get better at killing other people?
Because if those people don't , some other country will do it. It doesn't matter how moral you are , if you are weak and moral , you will get run over by strong and immoral people. Way of the world.
I watched a video of someone DIYing the one-pixel method somewhat recently. It was so pleasingly clever, I felt like I'd been let in on a stage magician's secret behind some awe inspiring illusion.
@krozareq The link, for me, doesn't exist, and imo is quite hidden to even find the embed for him, I didn't think it existed until I expanded his description and scrolled *all the way down* and even then, its a little rectangle with his YT logo + name... Edit: I see he's mentioned clearly in the video, hadn't gotten to that point, glad they gave him some credit
This is such a mind bending demo. A strobe is basically a fast on off light that turns motion into snapshots, and when the flash rate is close to the motion rate your brain can see something that looks frozen or even moving backward. The science hook is aliasing, the same reason wheels sometimes look like they spin the wrong way on video. What part surprised you most in this experiment?
@smilerbob If you're on a PC, you can use the comma (,) and full-stop (.) to move the video one frame back/forward. Click the timestamp, pause it as soon as you can and then just backtrack with the comma.
Edgerton’s method is how I learned breakdancing powermoves at MIT. Strobe photography overlay of my moves in motion, compared against a pro breaker, then calculating my joint velocities and accelerations. Told me when and where to move and by how much. Got me airflares.
Strobe videos are really cool to watch, what once looked like a perfectly still object is actually moving all over the place in a slow undulation, it's very mesmerizing to watch I recommend looking some up
@ninjanayr well then amateur in where the experiments take place then. Not all science bang takes place in labs. Some take place with throwing cards and silver benchy's in garages.
@ninjanayr The actual distinction between amateur or professional is not necessarily skill or capability, but whether you are getting paid. If he makes money doing physics, he is a professional.
@LaviBerkoi am not sure if he's an "amateur" as he/was working in a nuclear lab or something? But yeah, doing that in your garage applied science style, is rad.
@joeshmoe4207 I suspect you're referring to the accounts of his personal life and his behavior toward women? It seems to boil down to the classic problem of whether we can separate the scientist from the science. Also to call him overrated might make sense from a 'pop-culture' point of view, as his popularity overshadows that of many of his colleagues, but from a scientific point of view it would be difficult to dismiss his contributions to Quantum Electrodynamics. Also do you think it is fair to judge a mid-century figure through a modern ethical lens, or should the scientific contribution stand on its own? Beyond that, can we really dismiss his genius for explaining complex concepts through simple language without oversimplifying, just because we have ethical issues with his character?
@toumasuke I think it’s more than fair to judge Richard, the person, for his actions and the harm that his actions have caused with the continued reputation that many scientific fields have with regards to how women are treated. I do also think it’s unfair to claim that I’m judging him with ethics that are in any way modern. Many of the detestable things that he did were just as detestable in his day and he only got away with them because of his position and renown. Lying about his age to sleep with undergrads for years? And how is it that we can judge improvements in our collective ethics if not by judging the past through our lens and understanding the faults of the past. And while I do think his work stands on its own, there is no need to idolize him as a person. On the contrary, his stature in popular science and being held up as a figure to idolize continues to damage the field by propagating his actions is acceptable within the field. We value the work of Schrödinger and don’t try to launder his reputation as a pedophile. We value the work of Heisenberg and don’t try to launder his reputation as a Nazi. Obviously these are two extreme examples but my point stands. And with regards to whether I’m referring to his contributions to popular science or the field, I speak mostly about contributions to popular science because that’s what this video and comment thread is in reference to overall.
This was an absolutely brilliant video that left me feeling like I needed to watch it again. There were a lot of jumps from one cool effect (discovery) to another. Individually, the numbers all add up the overall the impact is beyond belief. That was a lot of material for 30 minutes.
I knew exactly where it was going to start with, as I still use strobe lights to time old engines. It really is fun to do, freezing something super fast so you can see exactly where it is
This feels like the equivalent of behind-the scenes content for photography fundamentals. I used to work in a photography studio, and I had no idea that this was happening hundreds of times every day in a machine the size of my palm.
you are talking about that 1 pixel photography? It reminds me of cartoon in the old days when artists have to draw every single frame and put them together.
6:50 look at his eyes! Am I the only one amazed that his brain managed to react to the flash of light, in between the moment the balloon was popped, the sound reached the flash, and before the balloon completely popped?
Very cool! I just came home with a treat, and definitely looking forward to see this a couple of times back-to-back to absorb the contents properly. Thanks for the upload man :D
I just wanted to express much I love the new guy! You guys have been dropping quality videos at a crazy speed and I really do appreciate it. Derek deserves a break and I’m here for it!
18:20 I think I know why it's happening and that it's just a side effect of repeating the pulse over and over, but it's interesting how it appears that the path the pulse is going to take is already a bit illuminated.
most likely it's because the laser still has some residual light emission between the pulses (the exact mechanism of which will depend on how exactly they're making the pulses)
@marieshade3744 It's not that this video is a clone of Brian's video, but it touches on similar concepts and might have inspired this one. Veritasium is over thirty times as large as Alpha Phoenix, so them giving a shout out is a nice and cool gesture, and especially if they were inspired by him.
@marieshade3744I follow them. I appreciate his work. Why do you have to diminish that? What's wrong with you? It would have been an oversight to not mention their work. They obviously agree with me.
Exactly. Since it still takes, with modern hardware, a few hours to path trace a single frame. (as happens in movies). Game path tracing is something different.
@donutwindy Not all to different. It's similar but to save on power a lot less rays are shot then denoised. Movies do it better because they take time to render. At least that's how I understand it.
@Madblaster6 They use a few other clever tricks besides just reducing the number of rays too. It depends on the specific game because RTX is developer customizable, but one technique is path tracing the whole scene in black and white with low-poly models, then superimposing the resulting lightmap into the traditionally rendered scene at full resolution. A bit reminiscent of the "scanning" techniques seen in the video, in that this only works if the scene is repeatable since the end result you see is basically a collage, but since it's all generated in the computer, of course it is repeatable! Then there are the LAME developers, who cheat by only having something extremely specific like water ray-traced, then just limit the detail slider so that "Ultra" setting is intentionally handicapped until you turn RTX on to artificially make it look better, but nevermind those dillweeds.
@Madblaster6yes, fewer rays. A lot fewer. 99% of rays are AI, adjacent pixels or borrowed from prior frames. And only a few rays per pixel instead of thousands. Priority is given to direct lighting. This works well in predictable smooth surface scenes like an urban jungle (cyberpunk). It would not work well in a forest or a candle lit room with rough hand carved wood and deep brick fireplaces. Movies actually compute each frame and use thousands of rays per pixel. They don't need to denoise. (And then, in movies, additional processing will happen by hand based on the directors vision for the scene) Real time path tracing. um. That's a hard no. Real time rendering with some path tracing. I'd accept that.
@donutwindy Movies still often denoise. Even spending hours rendering each frame can still have noise, so denoising is still important in non real time path tracing.
@21:40 the electron "wiggling" is (regrettably) incorrectly represented, as literally all EM waves, when animated (or in textbooks). It is shown to be wiggle in a plane but actually, as everything in Nature, it has 3D component, and instead of simple zig-zaging movement, it actually moves in a tiny spiral motion. That is what lambda symbol in the Maxuel-Heaviside equations actually predicts, as the movement is always swirling in the 3D space as there is always miniature (nano scale) inconsistency in either magnetic or dielectric permeability of space and the electron movent always follows vector gradient with the least resistance (highest permeability).
I mean since electrons have a negative charge, it can be easier to just use your left hand to represent its motion, rather than using the right hand rule and reversing it... The right hand rule only gives out correct directions for positive charges.
I love the content, but wish he would stop artificially adding so many pauses in between words. It’s way over done and I’m sad cuz I really do enjoy the videos but I can’t listen to him anymore

Hello
It is sad to remove the Arabic dubbing
at this framerate im still losing in cs2
Now I can blame that my opponent plays in a trillion fps to slide off the skill issue excuse 😭
Having higher framerate simply dilutes the effects from luck and your true skills start to matter more. Of course, the same applies for overall latency (ping + input latency + output latency).
Hahaha yeah me too :D

8:09 the solution for nighttime photography was just to strap on a huge ass flash to a plane
So, when you see the flash during a thunderstorm - chance is it's realy Google Maps taking photos!😀
@PavelKostromitinov and thunder is underground nuclear warheads tests ??
Who would've thought, right? Hindsight is 20/20.
I guess the problem was about not having a bright and compact enough lightsource to be carried by a plane.
And that's where his invention comes into play.
It has a bonus effect that wasn't noticed/commented on. If the gunner had an idea where the plane was, putting his sights on target, the flash would momentarily "blind" him. protecting the plane.
@PavelKostromitinov google gotta be paying LOADS to pilots or drones to fly in a thunderstorm
26:47 - That molecule is 4-aminophenol, used for, appropriately enough, developing film.
Good old rodinal!
very few molecules are fast, bright, stable, and predictable under extreme radiation induced oxidation. it's also a 1-electron induced oxidation which is handy in this case. it's also a precursor for the pharmaceutical molecule acetaminophen aka Tylenol aka Panadol
Take N-Acetyl-4-aminophenol if you get headache
@christiankrause1594 Paracetamol?
@suivzmoi which as we all know is a precursor to autism, also appropriate for the video.
“an Attosecond is to a second what a second is to the age of the universe” is the most thing that blew my mind! that’s insane!
I agree. That one was a lot to think about / take in, process. even decode what was being told to me. That's so fast, it almost doesn't exist.
At least it wasn’t the least
Two and a half ages of the universe actually.
@vladimirkuzin1153 yeah
Imagine at the quantum level, a universe of interactions in that timescale. Hidden variables no more
9:45 ghost effect of a card seems to be produced by a gun flash actually. Fascinating
Came here to comment that exact thing. The errant light bleed in the darkness is certainly not enough to produce a ghosting of that magnitude.
Wow thats actually brilliant you deduced that. Seems correct.
@darjanator Well if you'd like to really get pedantic, the flash from the gun IS the ambient light or "errant light bleed" or as you put it lol
@toxicity4818 This cannot be... I've been outpedanted! NOOOOOOOOOOOOO!!!!
Good point. good catch. Is the gun covered so there is no flash ? They should show that.
8:39 imagine being a German troop at Normandy on night patrol and then it’s suddenly daytime for a fraction of a second. Wake up in the morning there’s landing crafts outside
I'm reading through Rise and Fall of the 3rd Reich right now and that was my exact thought. "Eh? Did you see that? Hmm...never mind"
I prefer not to imagine being a nazi but you do you
"Just a lightning don't bother"
Two great tribes of common origin destroying each other.
from the ground I wouldn't be surprised if it just looked like a small camera flash going off at a distance, among the stars, I doubt it's actually like the whole field being lit up
this is what ADHD is like, dude was tryna fix motor power fluctuations and suddenly he's become a full time photographer
Oh wow, I thought I was the only one who immediately thought the same. I have a 101 unfinished projects here and another 101 which weren't the original goal and are--oftentimes--also unfinished. But, no worries! Because over multiple decades I also have at least 11 thoroughly finished projects, of which at least 3(*) stayed true to the original goal!

Dude....😮your in the wrong business.🤔(Me two)?🙄😡
That’s literally my life in a comment, seriously that’s exactly what happened 😂
adhd isn't that crazy
Yep lol
何を解説しているか全然わからないが、非常に面白い内容でした
But did Edgerton solve the mystery of motor's misbehaving when there is fluctuation??
Good question !
Yes, look up his doctorate thesis: "Transient Torque-Angle Characteristics of Synchronous Machines."
Right? It's like how many licks does it take to get to the center of a Tootsie-Roll Tootsie Pop?
The world may never know.
@klschofield71 he did, look in these comments
Just use a fluc capacitor!

Legit a cool story bro!
Props for shouting out Alpha Phoenix. I had seen both of his videos ages ago and was wondering if you would mention him.
Forreal, he does some absolutely wild stuff on is channel, and he needs more viewers
valorant?
@Orangutanism nah, he made a homemade strobe camera that can record at a billion FPS, its mentioned toward the end of the video
@BopsLearnedSom3thing18:51
They took too long. This whole video is based on what AP did already.
3:34 his wife looks so pissed 😂
Yeah😂😂😂😂😂lol
As a VFX artist this is funny to see, they're basically running a raytracing renderer in real life, shooting camera rays and sampling surfaces multiple times
The scene they used is also schockingly similar to the scene we made in our first raytracer
VFX artist? Independent or do you work for a company we might know?
@satanlucifer6099yeah I went to several! MPC, cinesite, framestore & method studios
Reality is just ray tracing
It kinda looks like a quick render too, with all that noise. Neat.
The guv at 26:11 - I have never loved any job NEARLY as much as this guy loves his job. His energy is great and he is SUPER excited to explain what is going on. That man is just happy to work there and that's awesome to see.
I feel like he has some Sheldon Cooper vibes :D

8:30 my grandfather was an aerial photographer during WWII. its super cool to learn how their job was done.
The research that went into developing the attosecond laser pulses we see at the end actually won a Nobel prize in 2023!! Very cool stuff 🙌
An attosecond is to a second
As second is to the age of the universe
The age of the universe is 13.8 billions year old...
I can not begin to fathom this thought
@prinlerdsri405same, when they told that, I swear I was thinking about how MINISCULE that is, for the rest of the vid

To think there's stuff happening at that tiny little miniscule slice of time is mind boggling.

Nothing can go faster than light?
Pfft hold my physics real quick....
I mean it's true nothing IS faster than light
If you're referring to an event horizon or something
Here’s the secret trick: it’s not the same photon in every frame. Not even the same photon in every pixel of any single frame, in fact.
watched this last night instead of studding for my physics exam and strobe lights literally came up out of the blue. I had no idea about them before this video (Edit- i failed the exam)
Glad I lived long enough to see this, because I've always been curious about it.
0:47 when you hear this song on a Veritasium video, you know you’re gonna learn some incredible things
Same in 9 out of 10 History of the Universe videos. Great stock track used to wonderful effect by many YT science-related creators.
9:26 Feels like the setup to a Columbo murder mystery.
The fact that a video of this caliber and quality is available for free on RUclips is simply mind-blowing to me.
These videos goes over my head every single time, yet here I am
*"What If You Keep Slowing Down?"*
I clicked on this assuming a thought experiment about a human experiencing time around them moving faster and faster around themselves. I am not disappointed.
17:00 i love how you can see the wave pattern of the light and its interfirence with its self
24:05 genuinely shocked me
Amazing video, thank you very much ofr putting things into context. Great!
If you are traveling on I80 in Nebraska, stop in Edgerton's home town of Aurora. It is home of the Edgerton Explore it Center, with several of his photos and information about his life. Our kids love the wide variety of hands on activities there.
Well I used to be proud I knew how to read a tape measure 😂
This is one of my favourite videos! Glad Veritasium pushed you to make your own videos:)
20:36 NEIN NEIN NEIN NEIN cit.
6:42 You can see the balloon half pop in the Veritasium camera too. If you’re on PC, you can move frame by frame using the comma and period buttons.
Impressive stuff man! i didnt even know we could move frame by frame...thank you
Wow! You can see how that image is overexposed
@PrayagPR-t8o same thing!
7:20 "once Edgerton showed the world how powerful strobe photography was, he attracted some unexpected attention"

0:55 Ohh we are in for a treat, as usual.
0:22 they really got the flash as the cameraman
As soon as I heard "attoseconds", it reminded me of how fast The Flash can think... ⚡
0:27 nah just use "zaaaa wardooooooo"
Thank you Gregor...excellent production.
I love how cartoonish Edgertons solution to military problem was.

Bless all the peoples who are extremely curious. It's truly awesome.
6:42 If you pause the video at the moment when he says: "pop!" You can see the balloon sort of being in a "half-popped" state.
That sounds like the stroboscope worked
Thank you!
The biggest part there being IF 🤣

@vink6163 athletics are just applied biophysics
Strobe videos are really cool to watch, what once looked like a perfectly still object is actually moving all over the place in a slow undulation, it's very mesmerizing to watch I recommend looking some up
18:50 I'm glad you gave him a shout out. Could have been a cool Collab
First guy I thought of. Amateur physicists managed to do the same thing as high quality researchers. Fully deserved shout out
It’s a stretch to call him amateur. He has a doctorate specializing in lasers.
@ninjanayr well then amateur in where the experiments take place then. Not all science bang takes place in labs. Some take place with throwing cards and silver benchy's in garages.
@ninjanayr The actual distinction between amateur or professional is not necessarily skill or capability, but whether you are getting paid. If he makes money doing physics, he is a professional.
@LaviBerkoi am not sure if he's an "amateur" as he/was working in a nuclear lab or something? But yeah, doing that in your garage applied science style, is rad.
I can't believe they made real life powered raytracing 15:25
You're saying they made a real life version of a technique that is used to simulate what happens in real life?
Or they just showing us how light behaves in real life. You can’t create physic.
13:21 @PheonixA lpha even showed that in his own garage 🤩
Watching this makes PAs garage video seeing the light travel even more crazy impressive.
Did you not see the shoutout they gave to AlphaPhoenix at 18:50 ?
Yes! In his garage! With homemade equipment. Insane :D
It looked easier to build than to program the motors and cameras to get a coherent image. Highly recommend all his videos
@ethanhermsey"Yes! In his garage! With homemade equipment."
that's the weirdest Iron Man quote I've heard so far
Wow, magnifiquement incroyable, et quelle merveilleuse ingéniosité 👍👏
7:00 called it
9:02 bro…my mom gets mad if I shoot a nerf gun inside, meanwhile you guys get to shoot a .22lr in the dark inside😂😂😂
are you my long-lost brother?
@lastyhopper2792might be😂
17:33 For a second I thought it was Andrew Garfield
Right??? I just commented that
was supposed to be bollywood famous actor, forced to be a scientist
Andresh garganish
It’s really interesting and impressive. I’ve learned a lot about this technology.
I love it when a science education video just sits down and inserts a video of Feynman explaining it. Nobody can do it better.
Feynman explained some stuff well but is overrated. Also a pretty terrible person but that’s beyond the point.
@joeshmoe4207 I suspect you're referring to the accounts of his personal life and his behavior toward women? It seems to boil down to the classic problem of whether we can separate the scientist from the science.
Also to call him overrated might make sense from a 'pop-culture' point of view, as his popularity overshadows that of many of his colleagues, but from a scientific point of view it would be difficult to dismiss his contributions to Quantum Electrodynamics.
Also do you think it is fair to judge a mid-century figure through a modern ethical lens, or should the scientific contribution stand on its own? Beyond that, can we really dismiss his genius for explaining complex concepts through simple language without oversimplifying, just because we have ethical issues with his character?
I can think of half a dozen people that can do it better, not even including myself. I love Feynman but he rambles and rarely answers the question. 😂
@toumasuke there is more to it. Let's stick to the physics fellas or else we can lampoon all of them. People are people.
@toumasuke I think it’s more than fair to judge Richard, the person, for his actions and the harm that his actions have caused with the continued reputation that many scientific fields have with regards to how women are treated. I do also think it’s unfair to claim that I’m judging him with ethics that are in any way modern. Many of the detestable things that he did were just as detestable in his day and he only got away with them because of his position and renown. Lying about his age to sleep with undergrads for years? And how is it that we can judge improvements in our collective ethics if not by judging the past through our lens and understanding the faults of the past. And while I do think his work stands on its own, there is no need to idolize him as a person. On the contrary, his stature in popular science and being held up as a figure to idolize continues to damage the field by propagating his actions is acceptable within the field. We value the work of Schrödinger and don’t try to launder his reputation as a pedophile. We value the work of Heisenberg and don’t try to launder his reputation as a Nazi. Obviously these are two extreme examples but my point stands. And with regards to whether I’m referring to his contributions to popular science or the field, I speak mostly about contributions to popular science because that’s what this video and comment thread is in reference to overall.
15:53 bro that one speck on the left is making me tweak bro💀💀💀🙏🙏🙏
speck* spec is specifics
21:53 My electrons don’t wiggle-wiggle, they fold…
😂
This was an absolutely brilliant video that left me feeling like I needed to watch it again. There were a lot of jumps from one cool effect (discovery) to another. Individually, the numbers all add up the overall the impact is beyond belief. That was a lot of material for 30 minutes.
4:57 "Magazines were essentially the social media influencers of their day."
Jesus Christ, have we already forgotten?
No, but there's a whole generation growing up now who may never have held a magazine in their hands
For myself later - his could serve as a neat detail design for blade... No?:
3:00 - for the old medieval thing feel (smaller it down)
7:25 of course, the military is finding a way to use new technology for war.
If you don't , someone else will. Better to get ahead of the curve
Every video Veritasium makes, is always so understandable.
Veritasium is the Edgerton of youtube science videos. There are millions out there but none with this storytelling ability.
There are some AI channels way more engaging.
@PearWhiskno there is not
Do you realize that is not veritasium anymore ? He sold his channel last year
bro can't even pronounce Edgerton properly...smh.
History of the universe. Check them
I knew exactly where it was going to start with, as I still use strobe lights to time old engines. It really is fun to do, freezing something super fast so you can see exactly where it is
1:14 Lester?
One thing I enjoy about this channel is the put a timer for the add so you can skip it or know how long is left.
11:14 fine I’ll do the dishes jeez
And I’l go to sleep…
Thank you for this comment 😁 A laugh that was really nedeed
We may not be brothers by blood but we sure are by undone dishes XD
You better do that with your heart and soul
7:59 could you say the plane was over exposed? 👀
Oh no 😊
4:32 Behind every successful person is a nagging partner who gives them that final push toward success. 🤣
You can say man and wife. It's ok.
@nicholasgeezy1329 It’s okay. I wanted to be inclusive.
@james4807Mbut it just sounds cringey, forced, and unrealistic. This new trend of saying "partner" always makes me laugh.
@nicholasgeezy1329 Because I know many female scientists and how supportive their partners are.
the idea of being able to, and then actually, see electrons blows my mind!
I feel very smart while watching this
Me too - sadly that fades in less than an atosecond 🙂
Really, I counted 6,799 things I didn't know ......
This feels like the equivalent of behind-the scenes content for photography fundamentals. I used to work in a photography studio, and I had no idea that this was happening hundreds of times every day in a machine the size of my palm.
you are talking about that 1 pixel photography? It reminds me of cartoon in the old days when artists have to draw every single frame and put them together.
6:50 look at his eyes! Am I the only one amazed that his brain managed to react to the flash of light, in between the moment the balloon was popped, the sound reached the flash, and before the balloon completely popped?
Good catch man, thats incredible we can subconsciously react to stuff like that but toi our brains we have no idea wtf just happened😂
He knew balloon is about to pop that's why.
@Ea-nāṣir-Coppershop-Ur hidden variables
Very cool! I just came home with a treat, and definitely looking forward to see this a couple of times back-to-back to absorb the contents properly. Thanks for the upload man :D
The crazy part is that I just saw an article about how the just took first picture of an electron
10:28 he is very funny
From hand held cameras to 3.2km long camera
Photographers are always looking for a bigger lens.
@yngndrw. Exactly, the bigger it is, the better
the tiddy bot copy of this post got 787 likes and a like from veritasium, while this one has 51... wtf is wrong with the YT comments!?
@TS10852 idk man, people copy and get more likes and hearts. The originals get nothing, youtube is shiz
@TS10852 not even people, it was a bot. It links to corn channels and sites and it got like 195 subscribers in just 2 days since joining
In conclusion light move kinda fast lowkey
I just wanted to express much I love the new guy! You guys have been dropping quality videos at a crazy speed and I really do appreciate it. Derek deserves a break and I’m here for it!
17:40 this is 'bullet time' taken to the next level
18:20 I think I know why it's happening and that it's just a side effect of repeating the pulse over and over, but it's interesting how it appears that the path the pulse is going to take is already a bit illuminated.
They literally explain it.
Every frame you see is from a different event of the pulse & photo
most likely it's because the laser still has some residual light emission between the pulses (the exact mechanism of which will depend on how exactly they're making the pulses)
Damn😅
So we still have limitations that way.😢

Thank you for mentioning Alpha Phoenix. I was waiting.
Me too :D
Same here :D
are you related to him? what do you people actually get from fangirling
@marieshade3744 It's not that this video is a clone of Brian's video, but it touches on similar concepts and might have inspired this one. Veritasium is over thirty times as large as Alpha Phoenix, so them giving a shout out is a nice and cool gesture, and especially if they were inspired by him.
@marieshade3744I follow them. I appreciate his work. Why do you have to diminish that? What's wrong with you? It would have been an oversight to not mention their work. They obviously agree with me.
Awesome video and science.
Makes you appreciate path tracing more.
Exactly. Since it still takes, with modern hardware, a few hours to path trace a single frame. (as happens in movies). Game path tracing is something different.
@donutwindy Not all to different. It's similar but to save on power a lot less rays are shot then denoised. Movies do it better because they take time to render. At least that's how I understand it.
@Madblaster6 They use a few other clever tricks besides just reducing the number of rays too. It depends on the specific game because RTX is developer customizable, but one technique is path tracing the whole scene in black and white with low-poly models, then superimposing the resulting lightmap into the traditionally rendered scene at full resolution. A bit reminiscent of the "scanning" techniques seen in the video, in that this only works if the scene is repeatable since the end result you see is basically a collage, but since it's all generated in the computer, of course it is repeatable!
Then there are the LAME developers, who cheat by only having something extremely specific like water ray-traced, then just limit the detail slider so that "Ultra" setting is intentionally handicapped until you turn RTX on to artificially make it look better, but nevermind those dillweeds.
@Madblaster6yes, fewer rays. A lot fewer. 99% of rays are AI, adjacent pixels or borrowed from prior frames. And only a few rays per pixel instead of thousands. Priority is given to direct lighting. This works well in predictable smooth surface scenes like an urban jungle (cyberpunk). It would not work well in a forest or a candle lit room with rough hand carved wood and deep brick fireplaces. Movies actually compute each frame and use thousands of rays per pixel. They don't need to denoise. (And then, in movies, additional processing will happen by hand based on the directors vision for the scene) Real time path tracing. um. That's a hard no. Real time rendering with some path tracing. I'd accept that.
@donutwindy Movies still often denoise. Even spending hours rendering each frame can still have noise, so denoising is still important in non real time path tracing.
9:36 Albumcover Golden Earring - Cut
😂 I was hoping somebody else noticed that!
@21:40 the electron "wiggling" is (regrettably) incorrectly represented, as literally all EM waves, when animated (or in textbooks). It is shown to be wiggle in a plane but actually, as everything in Nature, it has 3D component, and instead of simple zig-zaging movement, it actually moves in a tiny spiral motion. That is what lambda symbol in the Maxuel-Heaviside equations actually predicts, as the movement is always swirling in the 3D space as there is always miniature (nano scale) inconsistency in either magnetic or dielectric permeability of space and the electron movent always follows vector gradient with the least resistance (highest permeability).
BRAVO
3:28 that's some funky music
21:46 Left hand rule???? I thought we all learned the right hand rule in physics
Using the technical current direction, it is the right hand rule.
Right hand is mostly used during induction
21:45 “the left-hand rule” I died a little inside.
🤣🤣🤣 Also 20:14
I mean since electrons have a negative charge, it can be easier to just use your left hand to represent its motion, rather than using the right hand rule and reversing it... The right hand rule only gives out correct directions for positive charges.
Freaky boy 😏
He was also involved with the development of image chips used in modern cameras CCD’s ‘Charge coupled devices’. A company called EG&G Reticon.
Vertasiums best skill is making the viewer doubt he has a point, and then blowing their mind wide open.
I love the content, but wish he would stop artificially adding so many pauses in between words. It’s way over done and I’m sad cuz I really do enjoy the videos but I can’t listen to him anymore
@justin1978😂 I never noticed. I think he speaks wonderfully tbh. I get your point however
