Capture video at 1,000,000,000,000 frames per second. Watch light as it ripples off objects and moves just like water. Absolutely crazy to imaging where this technology could bring us.

Cloaking Devices
Fear not my fellow Star Trek nerds and Star Wars fans who can recall the line “No ship that small has a cloaking device”.
The time has come and actually this one kind of slipped by us twice. It’s just only now that I have stumbled upon this article and it is wonderful.
As the story goes, the vikings, way back in the day, had a method of tracking the sun even when it was covered by clouds. This is obviously a necessary part of nautical navigation, so the question is, how’d they do it?
Well, those crafty pillagers figured out that when you hold a baseball size pice of calcite crystal (which is astounding they could identify considering most US college grads couldn’t pick out a pice of quartz if they were in New Hampshire - hint. its the granite state) up to the sky it filters light into two beams. When the beams appear equally bright, you are pointed at the sun.
Pretty awesome, right?
But here’s the kicker. Back in 2006, it was suggested that this mineral could be used to bend light around an object and in essence, hide objects. As you’ll read about in this article, researchers have managed to “cloak” an object that is visible to the human eye.
