You may have heard of the Bose-Einstein Condensate because it is one of the states of matter. Like gas, liquid, or solid, it has its own properties. Predicted by a maverick physicist back in the early twentieth century, it was only proven to exist in 1995. And it's pretty damn weird.
It's a discovery that's been decades in the making, but we have it on good authority that 2012 will be the year physicists either confirm or refute the existence of the Higgs boson — the "God particle," credited with giving mass to elementary particles.
