I havent been in physics since 1995 like 15 years ago.. I have a BS in phyiscs, but I started working in computer programming. I want to earn a PHD in physics
1) Should I buy halliday and resnick on amazon, with the solutions manual to review for the GRE physics
2) Should I study for a perfect score on the general GRE quantitative
3) My most serious question is on major.
I am iinterested in super conductors, and computational physics. should I chose computational physics or condensed matter physics even if research is in semiconductors?
