Off-topic, but if anyone has a chance to go tour the LIGO facilities, definitely take it! It is a very interesting experience, and highly educational, even for those that don't have a physics background. I've been to the one in Livingston while studying at LSU, and even after several years, I'm still astounded at the precision of the technology used there.
