People often think that there 4 states of matter: solid, liquid and plasma. But there is actually a fifth state of matter, the Bose-Einstein Condensate (BEC). The BEC was discover on March 20 2002 by Nobel prize winning Wolfgang Ketterle. Basically, what a BEC is that its a group of a few billion atoms that merge to make it a single matter-wave, a blob. What Ketterle did was that he cooled a gas made of sodium atoms to the temperature of 0°K (273,15°C) and few billionths above the absolute zero temperature.
