It's kind of a long video, but it's really cool to see light in slow motion. Also seeing objects around corners.

That.. That was amazing. I've always wondered what light looks like when it's traveling. Now I know.

That was truly fascinating, I wonder how long before it starts to bleed through to a specialist civilian market.

Since we're on the subject of TED, here we go:


An explanation of how copyright mathematics work...

Also, I love that prick-free blood test. The guy who delivers it seems so genuine and optimistic too, it's great to see.

This is why I love this forum. Nobody else I showed that video to understood how cool it was.

Only four people in this thread seemed to as well, Phaelax. Damn shame.

Gotta be honest, I find the Bloodless Blood Test more inspiring, though. May not be a technological landmark like seeing light move is, but the attitude of the guy behind it just makes it so likeable.

I thought it was awesome, but this is old news and has already been posted about in the past

Great video.

I didn't realise at first that it's not filmed in real time, or am I asking too much Still pretty amazing. Now I want to see one photon travelling across the room

Wouldn't this sort of mean this camera is several times faster than the speed of light?

Each frame is taken in the time it takes for light to travel 0.6mm...

So probably almost the speed of light, but FPS and M/S don't really translate.

My understanding is that you are not seeing the same piece of light travel from one end to the other.

I guess it is like a strobe light which may flash for any amount of time(perhaps even minutes), the trick is in the timing of each frame to capture the illusion of movement, along with really really fast shutter speed.

Nah, he explains that they light a laser pointer for a minute fraction of a second, which creates a "bullet" of light of a certain length. This bullet is what you see, though it takes multiple runs of this technique to build a tangible picture from it.

Yup. I forget how many times they had to flash the light in order to record the picture, but it's a good amount xD

Cool, but impossible as it would require that photon to somehow give of other photons so that those photons could enter the camera and be seen

I was thinking this. It's impossible to view a photon 'side-on' since the reason you see stuff is because energy (photons) is entering the lens and stimulating stuff (technical terminology).

Yeah true, guess we only ever see the photons that enter our eyes

perhaps a bit of dust particles or smoke may assist in the recording of that?

How do you propose that would work?

This brings up another thought, we have to not just get a 1 trillion fps camera to record a photon, we would also need a 1 trillion times zoom

I know this is doable.

(that's with electrons but I think I've seen photon-based ones too)

But at the same time... They're not particles. To view "the photon" you couldn't observe it, you could only simulate it.
