- www.ted.com Ramesh Raskar presents femto-photography, a new type of imaging so fast it visualizes the world one trillion frames per second, so detailed it shows light itself in motion. This technology may someday be used to build cameras that can look "around" corners or see inside the body without X-rays.

It took CZcams 7 years to recommend me this??? This is one of the greatest thing a human can see in their whole lifetime!!!
Love how everybody is being shocked of the "speed" this video of "catching the light" reached its viewers.
It really isn’t… This is all smoke and mirrors because the camera is only creating computer-generated images by information that they are pre-programming into it… There’s a reason this is seven years old and we haven’t heard about it...it’s because it’s all bullshit pseudoscience
@@davesims7917 "This is all smoke and mirrors because the camera is only creating computer-generated images by information that they are pre-programming into it… " That's what all cameras do. Why does this completely normal factor of all cameras make this pseudoscience?
Same here
8 to me
7 years and this is still the coolest TED talk
this along with 6th sensse technology by Pranav Mistry TED Video
They didn't use a laser but white light. The light would have dispersed when it hit the bottle and then water. The shape of the 'bullet' of light is also wrong and should have the same cross section from front to back. The shape of the 'bullet' of light seems to change along the length of the bottle indicating that the separate photons have different light speeds? How is it possible to switch the source light on and off in such a short time? (approx 10e-11s)? Its amazing every comment here praises the experiment without question. In my opinion the experiment was contrived and animated. Coolest TED talk? More like coolest TED lies!
@@johnnym6700 even if they had used laser light i think its still a very big achievement because laser light also travel with speed of white light . This techology can be used in many things .
@@arunsharma-ze1sl Sorry not possible. Fake experiment. Did you not read what I said? What technology?
@@johnnym6700 ,TED is a very reputed platform this guy is from MIT i dont think they will do fake stuff . The detail technical aspects you are talking about people from quantum mechanics better comment about it not i may be you are something missing .
I told my dad that if the sun went dark we wouldn't know it for 8 minutes. His response was, "why did you have to tell me that".
Science is a passion for me. This is a revelation. We see light with our eyes as being instantaneous but it's not. It's one of the fundamental things people should know.
Nobody thinks you are a genius because of this by the way
And I still can’t get 60 frames on a dam PlayStation
@@thejam7129 you can't get it on Xbox either
@@atartup pc master race
@@thejam7129 go to the doctor you idiot
PC is also same.
If you do the same scene over and over again, and merge your frames, you can get 60 frames per second :) That is exactly how this is done.
As a PC gamer I can confirm that if you play under a trillion frames per second, you're a filthy casual
2 trillion get on my level bruh!
Dont start telling me you cant notice a difference between this and 140fps, i clearly do, i just know i do.
But the human eye can only see 10fps xdddddd
Will Hedley U fkng skrub, 1v1 me
i would like to see a solar eclipse with that camera
A well deserved standing ovation. We can hardly imagine what we may discover by observing light in slow motion.
TED: imaging a trillion frames per second
Console players: but...but the eyes can only see 60 frames per second
I believe the human eye can see up to 1000fps but gamers are just sad
@@TheAviationistKhizr Literally nobody asked you. What's sad is posting videos of roller coasters on youtube.
@@jaggerjdm9787 No what's sad is posting animations and using bandicam screen recorder with a massive f watermark. Also no one asked you to use CZcams, no one asked you to watch this video, no one asked you to look in the comments and no one asked you to reply to my comment. So if you've got a problem then just leave moron.
@@TheAviationistKhizr I second this
@@pallav8725 appreciate it dude 😉
I also saw this put into use by archaeologists to scan an entire area of a abandoned village. What they found was absolutely amazing. just with a flicker of light, they were able to map the entire surrounding area plus find hidden tombs or underground rooms/areas, never before seen.
yeah, I realied a possible use after watching this. on a galactic level, consider gamma ray bursts or other frequency light distributions that occur from bursts or explosions of stars. if you were a neigh omnipotent existence with unlimited computational potential you could scientifically use this strategy to map sectors of the galaxy. Sure, the immediate few light years are destroyed to generate the power needed for the scan, as well as the star itself, or even potentially not. he'll, you could scan an area of space and use the refracted back light to tell you about what existed there if you are some 4th dimensional existence where time isn't felt as linear. it wouldn't matter by the time it reached bounced off the planet and reached back to you it was destroyed/the planets relative time everything on it was long dead, you could still access it by "pulling up" that snapshot of space to explore the data set further. Especially if you could interpret everything as data and reverse it back into what it was with perfect comprehension.
Who the hell was his audience? These people just saw the speed of light, the fastest speed there is in our world. And they saw it slowed down enough to see it move in SLOW MOTION! Do they not understand what they just saw? The audience at the iPhone 5 was more excited than these people. This is easily one of the most incredible advances in science! The ability to see the speed of light... it's pretty fucking awesome people, get hype!
+Second Zeta Without light, there is no angry birds
+Slevin Reviews This isn't my first time watching, but the first time I've looked at the comments and I agree with you. I was just amazed that people weren't shouting and cheering. As another commenter said, why didn't people stop me in the streets about this stuff. This is AMAZING stuff.
Oscar Conroy Maybe they aren't aware of this technological breakthrough. Being able to slow down the speed of light, enough to observe and study it, will provide science/engineering a whole new field to to draw inventions from. It's the fastest moving thing in existence.
As brilliant and amazing as this is, it's a computer animation based on a composition of repeated exposures, not a recording of a live action event.
Slevin Reviews when I am amazed I usually don't say a word for minutes because I'm left speechless. I would not be surprised if none of them said a word.
This is the most incredible thing I've ever seen! But why aren't they redoing the double-slit experiment? I would love to see wave-particle duality in action. From what I can tell here, it's less a duality and more... splashy.
And why am I just now hearing about this? This is from 2012! People should have been stopping me in the street to tell me about this.
Me too! The duality! Count my vote here!
Jason Flaherty I agree it would be interesting to see, but if i was a betting man i'd say that we would still be performing a measurement, and the result would be much the same as with any other measurement. Particle behavior
+Jason Flaherty I so much wish Vsauce doing a double slit experiment with this incredible camera.
+Jason Flaherty SAME HERE! WHY AM I SEEING THIS JUST NOW???
+Mephistolomaniac You're absolutely right, and I think it's important that people understand this point. *If you know what slit the light is going through, expect particle behavior. It's when you don't know where the light is that nature is at her cheekiest.*

Since i first found this video back in 2013 i have rewatched it probably 10 times either on my own or sharing it with others. This is amazing that we are seeing an event that moves at a speed so mind boggling fast and its not just interpolated data on a paper, it is actually physically visible in a way that no one thought could feasibly be witnessed.

Double Slit experiment please....
that would be awesome!
It is not possible. Experiment is based on photons, we can see it in high speed, but not magnify it to photon level
no. its just light from a laser
the light would probably change its behaviour when it's being watched. i agree though, give it a try and make it possible
+mono lith
We really need to get an answer to that. It's such a crazy thing--
That you can just look at particles and they change on a quantum level.
They should implement femto photography into the large hadron collider! That would be interesting
+Avelino Davila Brilliant idea! Faith in humanity restored.
+Feynstein100 no it isnt. Femto cameras dont work like that.
Almostbauws
Yeah I guess. They'd have to do the same experiment millions of times.
***** yes and it would be almost impossible. And not millions, but billion times.
+Feynstein100 The LHC does 10 million collisions a second. This technology, despite its vast number of potential applications, isn't suited for imaging collisions in the LHC, that's what they have their detector for.
So CZcams basically decided to recommend this to me in 2019
Hmm
Right..
Devyani Patil thats so cool bro
Exactly
Saw this ages ago. It's back
I got in 2020 march
That last line was almost like a punchline in a stand-up comedy - It's about time. Loved it!
Its 2018 and I just saw this. What has happened since then and why people aren't aware of this? Shouldn't it have been plastered all over the news as a major breakthrough? Or I was just living under a rock this whole time ...
Valentine yeah.... agree
Ik right
I saw it today 😂
Seems, it wasn't THAT spectacular as it was represented. I guess, because it's just usable for still images, and not for moving things. So, what's the point? Maybe usable for some particular science cases, but that's it.
Nii P. it's not just just used for still images, they literally showed you the camera recording at the a 10 billionth of a second.
Extremely interesting and well presented!! Thanks for that TT.
Me : see how much the technology has improved today.
Also me : wait.. it's 7 years old
Lol me too
It now 10trillion fps by caltech
Haha right
No its actually 30 years old...this Raskar guy is a phoney, he is simply using a camera (called streak camera) that scientists have known about and using for many years. There was even a nobel price in 1998 for femtosecond spectroscopy. This guy is showing light going through a coke bottle, which is useless, will only work for TED talks which are all useless anyways.
@@nevertheless123 well he is much successful and doing something with his life unlike you
First TED talk I ever watched. I still come back to it after 7 years
AMAZING!!!!
THIS GUY put his life to good use👍👍
2020, first time seeing slow mo of a light beam. Amazing as it is, until I realize the talk was given 8 years ago! Now, isn't that something!
No it isn't :) Because it's not a slow-motion video. It's a time-lapse built out of frames taken out of several events. Still amazing synch and timing, tho. But not a slow-mo video.
The coolest and best Ted talk ever seen and undoubtedly one of the best video in whole CZcams !!!
This gave me chills, very cool! Thank you.
Wow I'm 4 years late
its never late to learn bro

A fantastic presentation by Mr. Ramesh, the concept is just awesome. But what was with the Audience - could they have been any less enthused?
Isn't that obvious? They like Pepsi.
I think the audience did a pretty fine job. They applauded, laughed at the right moments and even stood up at the end. Tf did you want them to do, scream like it was a concert?
@@NipapornP Well played!
They were social and commerce students
They are gender studies major
Epic! Very intelligent man Ramesh Raskar ! Love you and your teams ability
.
WOW! really the best video on CZcams. I've always thougth about those very very very fast time scales. Amazing.
2 minutes footage = 10 yottabytes xD
Tales Demidio yea how tf can they store that
They don't capture very many images. They may only capture about 100 images in total (I'm just saying 100 as an example. I don't know how many). Our own brain can comprehend about 24 frames per second, so 100 frames can produce a smooth 4 second video for us. Hope this makes sense.
Tales Demidio 7h byh
Not exactly true, the human brain interprets visual motion with a frequency of around 7-24 Hz. However, when interpreting visual information, some studies have shown that certain individuals (trained fighter pilots) can interpret what is presented to them visually in 1/220th of a second. This corresponds to 220 fps. The brain doesn't process "frames" but more or less direct light, so it's a tricky question. This website does a good job explaining it:
www.100fps.com/how_many_frames_can_humans_see.htm
They dont need that much storage. The recordings themselves are less than a picosecond long.
Screw scientific applications. I can finally take a picture of my wife with her mouth shut. My life is now complete.
Hilarious!

+Scah Saint HEYOOO :)
One of those TED talks on science which I can completely watch till the end. Beautiful innovations.
Amazing! This is truly awesome!
They aren't really taking a video of a single event. They are repeating the event a trillion times and taking frames at different instances in time to get one full event. So if you think you can use this as a slow-mo camera to capture a water balloon bursting, you better have a LOT of water balloons...
I think you wrong on this one. This camera sees light around corners, by capturing the light when it returns.
+DJrezafication "resimulated many times" - last time i threw caution to the wind when i heard that. now i think twice yes, it must be run again and again.
+DJrezafication it's relative, this is how light works, it's doing all over and over again, our cameras do these things too, only at 60 or 30 fps.
Miseew No he means the light beam is fired multiple times and the camera is actually recording millions of simulations of a light beam being fired and compositing it into one sequence.
+jonnypanteloni Yes, there are no sensors, no electronic components, no CPUs available that are fast enough to capture a single beam of light as it travels a trajectory that short.
A talk from 2012 and it's 2019 now. 7 years hence, no implementation of this tech. Something's wrong with either the tech itself or the people who pass patents.
Most probably investors want to put their money into facebook-like apps... and competition like X-ray is well established.
Idk I feel like technology is far more ahead than we know ? They just keep us a couple years behind
Well, it's data heavy, and needs large and expensive equipment. Not everything can be scaled yet.
It's the tech, really. It's just an amazingly accurate timer that takes one photo per photon packet, just one femto second after the other, forming a time-lapse. Not really a slow-motion camera :) Amazing synch, nothing to say about that... but wrong sensationalistic aproach.
I have met this man in personnel. Very humble, down to earth personally. Ramesh has got number of unbelievable achievement in very short time. I am proud that, he is from my hometown. Congratulations 💐
Incredible. Seeing round corners. Utterly amazing.
Dude(speaking from future 2019),you talk of changing the future,but no one knows about this research.....

For normal people? You mean the people that scientists make touchscreen cellphones for? Or how about your computer? There's plenty of uses for it, but I can tell you're a bit slow so it's not worth it to bother to explain.

This is truly amazing research. Also, Ramesh is a great speaker and truly captivating the way he talks about his research.
Why not take the Coca-Cola label off?
+1nzi
"Coca cola did not sponsor this research. * fake grins * i just picked a random bottle and made sure to placed it in such way so the logo can be easily read,just so you know im not selling out or doing commercials for anyone"
I dont know who does the Hindu guy think he is fooling but not me that's for sure, its clear that he is doing cola commercial.
+hategoogle plus Yeah he really was insulting everyone's intelligence with that. He knew this would be absolutely groundbreaking video footage, and his lab likely shopped around. I know it's a small quibble, but this honestly put a damper on the whole presentation for me. I detest blatant dishonesty.
+1nzi Sponsorship monies...
He must have monetized from Coke as well.
Maybe they wanted to see how the light reflected off an opaque label, as rest of the bottle is translucent. :P
I love the praise in the comments for this TED Talk. This whole concept, technology, and optical science is fascinating, but more importantly the pace, articulation, and overall just extremely well-communicated message was superb!
A friend showed me a NOVA video that covers this, point by point... 9 years later. I told him I had *this* video from a decade earlier... Bullet through Apple, coke bottle, tomato, looking around corners... Everyone awes at the demonstration, but I hope this is being developed and grown, and not just the same old experiments repeated for the next video crew to film. One thing that _has_ come true, is that mobile devices have gotten cameras that arent just more megapixels, but record in much lower levels of light and at much higher frame rates. Good to see that prediction come to fruition.
This is groundbreaking and I can't believe I hadn't seen it until now! We really need to reevaluate our priorities as a species; I'd much rather have seen this on CNN than Justin Bieber's latest offense. That was the day I quit going to them for news.
Also, notice how you can't see the light until it refracts through the medium? In other words, if there hadn't been a water bottle in the way we would never have seen the pulse. This is obvious to most, but it is fascinating to actually see it in action!! Astounding...
Good spot. If you aren't already in the field of alternative physics, we need a few more like you that can use their eyes & brain in concert! (providing you have a strong stomach, you do have to pick the few gems out of a load of stinking bulls***)
lynx tamer i think we already knew that because light seems invisible and we only see the affects of it bouncing off of all the objects. Otherwise we would be seeing the light and colors streaming by our eyes and filling the room all of the time. But that was very observant of you. I need to rewatch this to see what else I missed.
fake news
so how long until someone points this camera at the dual slit experiment?
@m ・ ́ω・ where did you hear that it? So youre saying if we could somehow observe the electrons without electromagnetic radiation that we WOULD see a wave??
I can’t understand how a person would even dislike this video after watching it? You just experienced and saw light before dying out dude, respect that.
Absolutely mind blowing
So anyone tried double slit experiment with femto-photography yet?!!
What would be the point, the electrons some how know when we are measuring it anyway.
***** What?
that is a brilliant question
revisit the michealson morely experiment

This is probably the coolest piece of technology I've seen in my lifetime. We're watching photons in motion!
Fascinating. Seeing light slowed down - What a hoot!
Now put this in a smartphone so my laser pointer looks like a light saber!
Check out styropyro in his recent videos he has demonstrated this
887 dislikes from conventional camera producers? I want to believe that they also liked this.
Some might be from people who hated this to be advertised as a "faster than light camera to take slow-mo videos of light" instead of "Synchronization tool to take timelapse frames with 1 femtosecond of increment on the timer". Precise and amazing? Yes. No slow-mo video, tho.
FANTASTIC!
Totally awesome ...
HAH That man was geekin when he said "It's about time" I love it
This is so exciting! I can't wait to see where this will end up in ten years, or maybe even as soon as five years. Technology is moving so quickly, there's no telling what will be done with this breakthrough!
nothing as of now. 6 years have passed 😐

Это потрясающе! Спасибо.
absolutely astonishing
Second watch in 2019-Still I am in awe! :P
2nd watch in 2020
two ladies didn't clap at the end
Probably they were not Indians.
Perhaps they are part of the team or related and heard it a thousand times.
I saw 3 ladies who weren't clapping. And possibly 1 male too. :)
They were the military intelligence operatives who realised what they were seeing and weren't clapping because they realised the implications of India having this technology before anyone else.
Leave them alone....
Probably because I waited half my life for images of photons in (slow) motion, I'm as impressed with Ramesh Raksar's film now as I was when I first saw it a few years ago. Give that man a Nobel prize!

7 years, *STILL* the coolest TED talk ever
How are the photons reaching the camera before they reach the end of the bottle?
+dLimboStick They are, what you see are photons "breaking off" from the beam of light, those photons are what reaches the camera. In other words scatter from the beam
+FoolishBalloon Therefore, since the camera can see the entire bottle, that means the photons have bounced off of all those parts of the bottle and the claim that the bright spot we're seeing is a traveling photon is bullshit.
+dLimboStick No it's not bullshit, it's simple physics, you are just looking at something that happened in the past. Just like when you look at the sun you are looking at how it was 8 minutes ago.
+dLimboStick An other way to look at it is like this: look up at the night sky. many of the stars you see shined the light you are looking at hundreds, if not, thousands of years ago. Its possible that some of them have already exploded in novae. furthermore, none of the stars are where they appear to be because they have moved since they emitted the light you see them with. I truth, the laser likely collided with the end of the bottle, before you ever saw it enter the bottle to begin with.
Joseph Marsh
Impossible. If that were true, then what we're seeing entering the end of the bottle is not a photon. You can't have it both ways.
May be it's better to remove the Coca-Cola adv.
why ? funds is mater for the great research, focus on Genius technology please, thank u
Awesome!! Mind blowing realy
Interesting and well explained
We need to perform the double slit with femtophotography! Maybe then we can understand the paradox of light being a particle, a wave, or something else!
