De-stress while waiting on graduate application results: design a physics reality show! (I had part of this in another thread, but I think it's funny, so I'm putting it here for you to appreciate).
Here are my thoughts so far:
"American Physicist" (auditions with Maxwell's equations, perturbation theory and special relativity derivations)
"Are you as smart as a physics graduate student?" (teeheehee)
"Extreme Math Makeover" (replace all those vectors with tensors, and use Einstein summation convention!! and let's do contour integrals! )
"Who wants to be a theoretical physicist?" (prize is a research grant instead of $1 million)
and the best of all, ETS's new GRE offering:
"FearFactor, ETS Edition". You have to sit in a claustrophobia inducing box covered with spiders while answering 100 rapid-fire physics GRE questions in under 1.7 minutes each. If you win, you get into graduate school.
