It’s bizarre to feel awestruck and disappointed at the same time. Yet this is often how I feel when I read articles about ultracold atoms and Bose Einstein condensates. I’ll get to the awesome and awestruck parts later, but let me explain my disappointment. These experiments sit right at the boundary between classical and quantum physics. When we play with ultracold atoms, we make macroscopic objects do quantum things. And what have we discovered? That quantum mechanics is pretty much correct.
