Probing Quantum Behavior in a Large-Scale System

Quantum mechanics, it seems, is where physics breaks from making intuitive sense. In the realm of the infinitesimal, particles can be in two places at once, or display the "spooky" properties of entanglement. But it might not have to be that way--a few months ago, the good folks over at Veritasium put out a fantastic video drawing attention to an amazing phenomenon that was only recently discovered: a macroscopic, intuitively friendly system that behaves almost exactly like a quantum-mechanical ...
