The Connection Between The Beatles and Quantum Physics?

Tonight was the final lecture of econ 102. Again, we stuck around after class for nearly 2 hours having discussions with Larry. One guy asked him if he should buy google stocks, this girl asked how we can train ourselves to be more innovative, but me, of course i ask "Do you like The Beatles?" But unlike most other profs, he took the question seriously. The most interesting part of his reply was when he explained that the reason why we as humans enjoy music has a lot to do with quantum physics in our brain. So far, I think he's the only guy i know who can take a discussion about The Beatles and turn it into a discussion about quantum physics! Strange but interesting. He also told us he was a baby boomer, which finally reveals his approximate age! This is a guy who doesn't like telling his students how old he is, so it's a big deal!
