This is insane… seeing light move as a wave as a physicist makes me tear up.
I agree with you. As a scientist myself, I am fascinated to see something so profound reduced to a visual. To be able to see light travel, a mundane thing in our lives today, like this is absolutely astonishing. I'm going to share this with all my colleagues.
It’s okay to cry man. I’m not a physicist…. And I’ll cry with you
Get your ass outside and absorb some photons!
I would really like to see the double slit experiment done with this.
But then it will always look like particles, won't it? If only we can see the wave interference pattern...
Doesn't it sort of see it by measuring the different paths of each photon packet? The individual calculations for each packet would make me think that.
Makes no sense
I was thinking the same thing just to see if they could catch something even slightly different.
😎👍👍
This video was uploaded 10 years ago and I had no idea of such camera. Any update?
That not really a live video, it is same config laser shooting, each time only capture one slice, repeat 500 times with offset, and combine the whole video.
Still not enough fps for CSGO.
10000000000000fps?
@@idku889 that's a good fps for noobs.
@@idku889pffft. I've seen people play siege react faster than that.
BAHAHAHAHAHA
I cAn FeEl ThE DifFErEnCe
Your FPS is fine. Now, we need to work on your gbps
This is probably one of the most amazing things Ive ever seen
@Malcolm Tulip nah, you're just not able to appreciate how amazing this is.
@Malcolm Tulip You’re not wrong and neither are they. This will contribute to Einstein’s theory of special relativity. It could make quantum computing actually practical to use. I’m not smart enough to grasp it further than that but it will help advance science in a way that is meaningful and impactful on a broad range.
@Malcolm Tulip Fair enough. And my wife would probably kill me.
Why am I only seeing this now??
The ultra high speed photography being done at MIT is beyond even Prof. Harold Edgerton's wildest dreams. His high speed photographic prints have been classics for nearly two generations. The current ultra high speed technology is beyond the science fiction of Edgerton's day. By the way, the Edgerton print of a bullet piercing an apple is amazing, but Edgerton also did a high speed image of a bullet piercing through the planar surface of a playing card. That image is amongst his best in my opinion.
My 9 year old son is a huge science nerd, when he was little he preferred to watch science documentaries with me over watching cartoons. I was just discussing thr speed of light and the speed of sound with him...i was able to describe the speed of sound fairly easily as this is something he has seen, or better yet has heard with his own ears and can understand. For the speed of light i couldn't think of any examples of things that he has seen so we jumped on youtube and found this video...we were equally amazed and impressed, i hope to one day see full documentaries on this using high speed cameras...i cannot wrap my mind around a trillion frames per second...finally something faster than the US federal government spending taxpayer dollars!
Good for him. Never stop encouraging him to think in new ways/think creativity. Personally, I think kids are born curious and only grow up to be curious scientists/engineers/etc if they have a way to stimulate their mind like what you are providing.
@@andrej2375 I completely agree, his curiosity has only grown in the time since making the comment above. I actually have 4 kids, 2 girls and 2 boys with the girls being oldest...they are all curious about the world around them, more so than most, my girls excelled in science class and even won top awards in the annual science fairs. My youngest son is ten now and he has exceeded me in scientific knowledge. If something interests him he will search and search for any and all information about the subject so he can learn everything he can, he has me help him conduct experiments so he can see things with his own eyes and truly understand how and why something works. I can honestly say that I have discovered and learned more over the last probably 6 or 7 years than I had in all of my previous years combined. I myself have always loved science but he is on an entirely different level...almost obsessive but in a good way. His passion for learning and understanding is truly inspiring!
That's beautiful 🥹
A person on the ground sees the lightning flash before hearing the thunder because light at a speed of around 300,000,000 meters per second travels much faster than sound which moves at 340 meters per second- Google 😊
@yeejay6396 you're beautiful
Can you combine a femto camera with an electron microscope and observe the effects of light on cells, molecules and maybe even atoms?
you should do double slits experiment with this equiptment, i am really wondering
Crazy to think that in the photons pov is instantaneous and we're capturing them in slow motion.
MIT, ladies and gentlemen. Every human being who believes in logic and science should be proud of that school.
Are you telling me there's a camera that can film at light speed? What the F..? :D
+The world is crazy and you know it Noo,but there is a shutter speed controller in the camera so quick and precise,that can photograph different light beams from the laser at such a close distance,that when later different snapshots are stitched you get a full slow motion video,which looks like one light beam is filmed at the speed of light.But truth is different light beams were photographed.Now read that carefully,so you understand it.I am wondering what lens is used for that quick shot.It must be a hell of a pricy lens though.
No, that's not what it is. Each frame is actually a different pulse of light, and it's all stitched together to look like one continuous flow. It's impressive, but not quite as impressive as you think.
All cameras film at light speed.
@@jmerridew124Actually, yes.
Actually no, it’s faster
This is cool the light in the bottle is a great example. You see the light going through the bottle, however if it was going at the FULL speed of light, then the glow on the table below it through the bottle should be delayed, instead it is not delayed, it is the same speed, if not even faster than the light going through the bottle. Now the explanation for this is that Light does not travel as fast through water, as Light travels at approximately 300,000 kilometers per second in a vacuum, which has a refractive index of 1.0, but it slows down to 225,000 kilometers per second in water (refractive index of 1.3) and 200,000 kilometers per second in glass (refractive index of 1.5). So yes, they did catch the light partial, with this amazing tech. But even more amazing they caught the difference in speed of light through matter such as water, air and plastic. Also they are not catching true light, this is because the camera is actually picking it up, so that means the light to the camera see's actually has to go faster than the laser can produce. So 1 of 2 things are true, "A" the laser light is much slower than the actual speed of light, or "B" Since the picture is taken 500X the light you see is not actually the light in the picture but about 10 frames more after the light was actually produced. "B" Is most likely due to when you think of the Sun, it takes roughly 8 min to reach the earth, so where we see the sun, is actually 8 min behind where the sun actually is.
10 years later, how fast is this guy's camera today 🤷
No camera can still capture the speed of light. That still remains impossible.
NOVA! No disassemble!
femto-photography.... i still remember this word from 10 years back....
That is just phenomal. To be able to observe light pulse propagate..
MIT researchers are going beyond
how can the camera be "fast" if it doesnt move anywhere
+stfuyougotktfo mindblowing
+stfuyougotktfo :v the obturator moves fast (hides in the bushes and disapear)
+stfuyougotktfo im..ii..IMPOSSIBRUUUUUU
ahahahha
That was mind-blowing!
Seeing how this is a 10 year old video, I bet the military can already see inside a room by simply shining a laser pointer in a window or under a door.
I didn’t realize this was 10 years old!
incredible
it's a shame it can't take the pic in one go, but instead has to take 500 slices...
+How To Make Sushi Which isn't really capturing that same photon travelling. It's like snapping pics of 500 different people passing through the tunnel at different times.
+Roger Cas photons have no identity
Dan Hipp I need to refresh my science!
+Roger Cas no, you're not entirely incorrect, it's just that since photons are indistinguishable and can be in two places at once there is no logic in differentiating between them
That doesn't matter I want to see one photon packet, not 500 bits of 500 photon packets rendered together! +Dan Hipp
Finally, something that can record my sex life.
DrMrSuperAwesomeGuy best comment ever
lol
This. This is why I went to the comments section right away
🏆
Pbs always dropping that knowledge
This is really amazing stuff.
This is amazing!
This is simply crazy. So very cool.
This is awesome!
And 15 years from now this will be a feature in all our phones' cameras. lol
Dope af, love it.
mind blowing! so cool... now we can do so many other experiments with light properties...what can I say ... WOW!
This is friggin' awesome!
The worst thing is that a bunch of people believed this lie. Modern people are very - very stupid. It is immediately clear that the light does not pass through the plastic bottle - this is a fake. The light hasn't passed through the plastic yet, but is it already reflected on the table? What? And it is reflected only from one side, and not over the entire surface from the transparent bottom of the bottle. FUNNY AND STUPID LIES. An experiment with a wave and a tomato - computer graphics. But for some reason people took their word for it. Shame. It is not surprising that with such stupid people in the population - that in science, that in the government there are thieves and unprincipled villains.
Самое страшное, что куча людей поверила в эту ложь. Современные люди очень тупые , очень глупые. Тут же видно, что свет не проходит через пластиковую бутылку - это фейк. Свет еще не прошлом через пластик, но уже отражается на столе? Что? И отражается только с одного боку, а не по всей поверхности от прозрачного низа бутылки. СМЕШНАЯ И ГЛУПАЯ ЛОЖЬ. Эксперимент с волной и помидором - компьютерная графика. Но люди почему то поверили им на слово. Позорище. Неудивительно что с такими тупыми людьми в населении, что в науке, что в правительстве находятся воры и беспринципные негодяи.
That’s amazing!
Amazing!
Awesome!
amazing!
Thanks for that - for the camera and for the video.
amazing...
awesome!
I think the last demonstration shows how mirror works. The wall is used as a mirror with much less reflectivity instead.
Absolutely fascinating! :-)
very very impressive!!!!! Great science!
IDK IF YOU GUYS NOTICED OR NOT... BUT THIS VIDEO IS 3 YEARS OLD!!!!!!!! WHAT THE ACTUAL $#%#$%
+iVinVirus Do you come from the future, cuz it's still 2015 here...
no, check the upload date
Kristiyan Krastev 2013
You said 3 years ago, it's 2015 now, 3 years ago is 2012
+iVinVirus holy shit 3 years ago?!?!?! NO WAY U MUST BE FROM THE FUTURE OMFG!!
wow increible!!
How can you capture (photograph) light in moting when photographing is actually receiving light into the lens?
They capture the _reflection_ of light on the bottle. Each moment, the photon is reflected at a certain "slice" of the bottle. The moment after, it's reflected at the slice next to it. And so on. That way, you literally capture the motion of light ; not light itself.
The internet is crazy 😂😂😂
Just saw an article today about this 10 years later the internet is crazy 😂😂
Amazing engineering
And (maybe) someday we'll have this on an iphone... amazing!
10 years ago!
I'm hesitant to report this as misleading
Edit: I did. I'm pretty sure most viewers thought the camera actually films that fast (didn't process the 10 seconds late in the video that shows that the rest of the video is misleading). This is clickbait.
Super!!!! Slow motion!!!
That's awesome.
"The shadow doesn't appear instantaneously" - My god, where did they get this guy.
+James W you have to realize that his job is to ask questions the viewers would likely ask.
+Alysuis Who would be likely to ask that question?
+Walsh2571 Don't be so thick mate.
+James I think that is the point.
+James Underwood I don't understand the problem, he asks super generic questions, and doesn't help the viewer learn anything interesting.
what a time to be alive
how come the light from the bottle reach faster to the camera to capture the image before it reaches the other end of the bottle?? Don't we need something faster than light to capture the light travelling?
Light has its max speed in vacuum. In water it's speed is only 0,75 * c (lightspeed). Coca cola bottle is filled with water. This camera also isn't like ordinary one, they use multiple takes.
this would take about the year to watch
Did anybody ELSE come here from an Upworthy article that was posted just s few days ago in THIS YEAR (2023)?
The article was about a "new camera developed at MIT." How the hell is this new? lol
Still really cool, though.
I'm having the same toughts. Maybe development in process..?
Finally 😭
I remember Destin from SmarterEveryDay did something similar to this with a pellet gun.
My mind was just blown.
Wow, hard to even fathom such numbers.
I bet a 10 second video on that camera is about a 100gigs
Most defiantly more than that.
yeah
+Vasily12345 definitely*
Ayman B. At first I thought you were wrong, because I thought you could spell it both defiantly and definitely, but in fact I looked it up and there is a difference:
blog.oxforddictionaries.com/2014/10/definitely-versus-defiantly-difference/
I will take out an important quote:
"If you do something defiantly, therefore, you do it in a way that shows your obvious resistance, indicating a brave or rebellious refusal to obey someone or to accept something.
So here we have it: defiantly just has this single meaning: it’s never, ever used as an emphatic way of saying ‘yes’ and has nothing to do with being exact."
So thank you very much for your correction!
just kidding go suck a bag of dicks
*****
Poor soul. Lost cause.
Amazing! 😲
Giuseppe Denti 👍
I came here from my home page Google news. Damn,I am coming to know this now. Wow,a trillion frames per second camera!😍😍
Incrível!
This puts in perspective everything about The Flash comics.
that was cool
Do the double split experiment with this camera.
Trillionth of a second frame, NOT a trillion frames per second.
But still can't capture Chuck Norris sidekick!
you're seriously still making chuck norris jokes in 2015?
+Gautham Manoranjan and still gets likes
Gautham Manoranjan How on earth did you capture comment that old?
Its 2019 and I still like that comment
Next in surveillance
Why am i suggested to see this now ? Its 10 years ago
Well, actually might be difficult in real time use.. as not all the surfaces are hard and reflect light. Majority of the surfaces in day-to-day life absorb and are in motion. Though, I should say its amazing actually that we can capture a single ray of light in motion.
Please film a recreation of Young's double slit experiment with reflective surfaces positioned throughout so that we may visualize how a photon changes shape when converted to a wave over time! 🤯
I'm here for the photons!
Wow. I just.. wow
Should have done this for my jr. high science project.
This is great. Creation itself is(was and is) done in frames per (second) if science can create cameras recording correct speed,it will be able to film each movement as is created from beginning to end. Also could record and show that world of the unseen ( unavailable to the naked eye ,per say), spirit energies and so forth.
spirit energies? lolol
When I saw a presentation on TED a year ago, I thought they record it in real-time, with one pulse. Now, when I saw this, I feel kinda disapointed. A bit misleading information on what actually happens, and how they capture it.
The camera is still capturing the speed of light. That's pretty remarkable.
***** Yes, but it does not capture continious motion. It is remarkable, but they didn't put it that way.
Ralfs Zemzars
The camera is still capturing each individual pulse of light but in different places. They put those frames together and you have a slow motion video of light motion.
***** Well, a video is a frames moving fast enough, to make us think, that it's a motion happening, while actually, it's a very fast stop motion. What they did is, they captured one sector at a time, with multiple pulses, and to make the actuall video, they have stiched together those sectors, so technically, it's not a single piece motion capture, and they did not tell this, when they presented the femto-photography technology on revealing presentation, and I, as some folks here, thought, that they point their camera at a bottle and film one, single laser impulse, which is false and misleading.
Ralfs Zemzars This also means that it's misleading to say that with this technique "it would take a year to film the bullet through the apple". Actually, with this kind of method, they couldn't do it at all. So yes, it's very misleading... Cool, but misleading people.
In that case is it possible to record lightning as it hits an object
i would like to see how it spreads out and create the shapes itdoes
¨Please don't watch my insides with this. I'm shy.
The Slow Mo Guys deffinately need to get their hands on this!!!
Wow
Amazing technology. Despite his brilliance, I must thank Dr. Harald Edgerton for providing my father with a great education while at MIT, but hold him in disdain for send my father and others to their ultimate death due to exposure on operations Dominic, Swordfish, and Fishbowl as employees of EG&G.
Telsa was the one who had light ideas
I see both sides of the spectrum; how long before a 3d model turns into a live image, great technological achievements, at that frame speed, now i only hope those developing the cameras will respect privacy of humanity. On a lighter note, theres lots of potential for this
To respect privacy then may be also lead to fueling perverse actions of all kinds, to eliminate crime itself from society, if all was watched (except bathroom)-(ai dont need witness to that ever) there would be a totality of more good behavior; thus ridding man of his sincerity in sin actions.
first saw the light in motion 1:11
Subscribed
Wool over your eyes folks. Gotta watch the table. 😂
This tracking capacity would work very well with ai to develop stellarchrotography in space mapping trajectories for future space travel.
Why is the light refracted through the sides of the bottle, parallel with the particle? Shouldn't they be trailing behind as bow wake given the time it should take to propagate to the surface?
It's december 2023 and I got this on my newsreel bit this is 10 years ago ?!
So the camera is so fast the resolution becomes the frames? Yeah that makes sense 😂
oh history and pbs funk
I'm more impressed by the computer that would have to process all the millions of pictures (unless it works differently and only captures content for .0000X seconds or something.)
I just saw the video on another site and came here to click "like" (i never forget that)
Just a matter of time before we discover and document early time travel. Something that future generations we cannot see in this timeline probably perfected already
?
Maybe now when we see vehicles in motion in movies we won't see the wheels tuning the wrong way 😎 .. watching lil longer= You guys are in ✅ for the Nobel Peace prize 🏆
I think it makes me a geek because I watched this entire thing
This is scientific miracle.
