Reading through these makes me really miss my undergraduate days as a physics major. Only marginally related: If you ever have a chance to go to one of the LIGO [1] sites (Laser Interferometer Gravitational-wave Observatory), do go take a tour! I've been to the one in Livingston, Louisiana [2], and it is simply amazing. The technology used and the science involved is very interesting. It's also kid-friendly!
