• As many already know, studying for the physics GRE and getting accepted into a graduate program is not the final hurdle in your physics career.
• There are many issues current physics graduate students face such as studying for their qualifier, deciding upon a field of research, choosing an advisor, being an effective teaching assistant, trying to have a social life, navigating department politics, dealing with stress, utilizing financial aid, etc.

Six simple harmonic oscillations each of same frequency and equal amplitude are superposed. The phase difference between any two consecutive oscillations i.e., φn – φn-1 = Δφ is constant, where φn is the phase of the nth oscillation. If the resultant amplitude of the superposition is zero, what is the phase difference Δφ?

Seriously, can we ban people like these please? F***ing pieces of inept amoebas!
