http://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.

He can film LIGHT moving, but even at those speeds, it’d take him over 15 seconds to film our federal deficit.

Why does this make me think of that scene in “Over the Hedge” where the squirrel drinks the energy drink?

Cool stuff, but I don’t believe he’d be able to image light packets in a vacuum. We’re seeing the light from air molecules retransmitting some of the energy.

Yup. What we're seeing is reflection and scatter (notice that the fluid in the coke bottle was milky?). We can only "see" the photon packet because it's losing photons that eventually end up hitting the sensor in the camera. No photon loss (i.e. vacuum) no image. I'd love to see him run a slow-mo of light hitting the classic prism/refraction demonstration...

I can’t even comprehend the minds required to dream this up, let alone quantify, design and implement.
This world has some amazing minds in it.
