If you ever get the feeling that life is a blur, maybe it’s because the atoms that make up the world around us are always moving at speeds faster than those of supersonic jet planes (about 4,000 kilometers per hour). By cooling an atom down to a temperature of nearly absolute zero (-273 degrees Celsius), you can slow its movement to a crawl and then use light to trap and manipulate it. That’s what physicist Steven Chu, the new director of Berkeley Lab, did to win a share of the 1997 Nobel Prize in physics. Continued >>
