Thanks for the all the advice. I'd rather go in with my eyes open and aware. Our son is trying to decide among Caltech, Harvard and Princeton (waiting for that acceptance letter). He seems to be heading toward theoretical physics/astrophysics. His first research project won him recognition in both the Siemens Competition and the Intel Science Talent Search. He'll turn 16 in June and he's our oldest, so we're adjusting to this next step.

chenchuan, what is your Princeton daughter's major?
