Neutrino oscillations

Congrats to the new Nobel prize winners in physics. I actually just mentioned neutrino oscillations the other day. The solar neutrino problem was a pretty big deal for awhile there. Some of my fellow grad students worked on SNO and we had a pretty neat live feed of SNO events (pictured above). I recall a controversy about whether to dump some salts into the thousands of gallons of heavy water borrowed from the Canadian government to deal with background noise.
