Ramesh is sort of the new
Edgerton, who built cameras with exposure times down to something like 1/1,000,000 second back in the late 40's. Now we're looking at 1,000,000 times faster than that!
But wow, now I can think of light as an object, rather than some suffusing effect. That's a really different view from before. Never imagined it would possible to capture images like that.
FWIW a lot of things inside your computer happen in a time slot where light could travel only a few inches.
Hmmm...I guess everybody knows light travels a foot (300mm) per nanosecond, or a billion feet a second. If you shoot a picture at 1/4,000 of a second, a stream of light just 250,000 feet, or 47.3 miles long will impact your sensor. What does this mean? You'd think it would knock you over, at the very least.
