Basically you can sort elementary particles into two groups: Fermions (like electrons), which have half-integer spin numbers, and Bosons (like Photons), which have full integer spin numbers.

The Pauli exclusion principle says that no two Fermions can occupy the same state, this is why in Atoms each energy state is only populated by two Fermions (spin up and spin down).

Bosons however can occupy as many states at the same time as you have particles. Now, what happens when you put a lot of Bosons into some system (like some harmonic potential, or just a box) coupled to a heat bath, you will find that Bosons will occupy the possible states according to some statistic (or rule or formula). And what we find for Bosons is that even though the system provides heat to populate higher states, most Bosons will only sit on the lowest energy state. This is what's known as the Bose-Einstein condensate.

Btw, did you know Bose was an Indian?

A question about Bose-Einstein Condensate:
What happens if you cool down a BEC? Will it ever "freeze" or will it stay liquid no matter how close to 0K you go?

I thought they were an entirely seperate state of matter? Aren't they close to 0K by definition?
