I spent the summer of 1968 three meters under the Aegean looking for archaeological remains. A team was getting together to do an underwater archaeology dig, and the organizer remembered I was a physicist who could help with pumps and the Bernoulli effect and silt movement. I thought that sounded interesting. I took a leave for a summer and spent it with a high pay of 30 drachmas a day, plus food. It was fun. For DUNE, I basically build – or try to build – instruments to do interesting measurements. The oscillatory nature of the neutrino, now that we have demonstrated that irrefutably, is one of the remaining clear puzzles that we have a chance of solving. It seems a grand challenge. And it is interesting science that covers a broad range. You can do other things with the DUNE detectors, beyond measuring how neutrinos change, like studying supernovae. I’d like to catch neutrinos from another supernova. That would be cute.
