Light Collapses Step-By-Step

This is such a cool experiment. They are able to make non-destructive measurement of the photon number in a superconducting cavity, and then as they successively make this measurement, they begin to see the result converging (collapsing?) to a single number. Just exactly what quantum mechanics described!
