Ramesh Raskar on slow motion light — at a trillion [10^12] frames per second

Hi Kairos, true, it could be great teaching tool. I'll show this to my kids. Problem with Youtube is once you see first video it shows related ones and than 2 hours later you wonder what happened :D Eugen

Eugen, Yes, truly beautiful and illuminating, including the exponential decay of intensity and the way light bounces every which ways. Notice the bounce-back to the entry end? Then, see how picosecond pulses could be used to see around corners and into things? Light is truly amazing stuff. If I were teaching school physics still, I would show this to my students, you can see the waves at work. KF PS: Expands capacity of the old 3-d chalkboard in the head, too. kairosfocus

Spectacular! Eugen

When I buy my Chinese remake of the Japanese copy of the US original I will not faff around with Coke bottles. I will fire a photon at a double slit and collect my Nobel. Belfast

Ditto, thanks. kairosfocus

I see it. Barry Arrington

H'mm, it seems UD still has a dropped embeds problem. Pardon while I get this fixed. kairosfocus
