It is amazing sometimes what gladdens a physicist. I came across an article [Link] in one of my subscribed feeds describing how some Spanish researchers put a bead with fluorescent properties in a chamber. They then conducted an experiment of measuring the beads motion whenever a fluorescent photon was emitted. And they measured recoil!

With so many experiments focusing on making quantum effects large, like the one last week about entangling a virus, it is refreshing and invigorating to read of an experiment that is essentially quantum in nature having classical effect. Yes, it is very comforting to have a demonstration even at what amounts to the quantum level that momentum is conserved!

Early Birthday Anniversary present for Isaac. Fig cookies for everyone. And mayhap a splash of whisky?
