Okay, here’s a kind of freaky Friday quantum strangeness post. Now try to wrap your skull around this state of matter which isn’t a solid, liquid, or gas. I’m not even going to attempt to explain it. What I will do is give you the Wikipedia link to the Bose-Einstein Condensate, where you can try and get the concept this weekend. But if it was up to me I wouldn’t waste the time, and just let Professor Daniel Kleppner of the MIT Physics department sort it all out for ya.
