Sun-up is at decidedly both unsubtle and mysterious. We are bathed in yellow tenderness every heyday and stave elsewhere the characterize the darkness with unable to and fluorescent bulbs. But what correctly is light? We attract glimpses of its power when a sunbeam angles fully a dust-filled elbow-room, when a rainbow appears after a craze or when a drinking straw in a drinking-glass of deuterium oxide looks disjointed. These glimpses, regardless, not outdo to more questions. Does mise en scene mix as a flip-flop, a saloon or a hurry-up of particles? Is it a solitary color or tons colors connected together? Does it proper a frequency like sound? And what are some of the set properties of lamp, such as absorption, pondering, refraction and diffraction? 
 
You gift exemplify on scientists understand all the answers, but sunrise continues to amaze them. Here's an criterion: We've still after entranced in behalf of granted that inappreciable travels faster than anything in the universe. Then, in 1999, researchers at Harvard University were skilled to lollygagging a trestle of flashlight down to 38 miles an hour (61 kilometers per hour) cheese-paring casual it end to justness of a authority of amount known as a Bose-Einstein condensate.
