March 20, 2002: It's not often that you get to be around for the birth of a new kind of matter, but when you do, the excitement is tremendous.
"To see something which nobody else has seen before is thrilling and deeply satisfying. Those are the moments when you want to be a scientist," says Wolfgang Ketterle, a physicist at MIT and one of the first scientists to create a new kind of matter called Bose-Einstein condensates.
Bose-Einstein condensates ("BECs" for short) aren't like the solids, liquids and gases that we learned about in school. They are not vaporous, not hard, not fluid. Indeed, there are no ordinary words to describe them because they come from another world -- the world of quantum mechanics.
