It's now much harder to become a next Einstein than it was before because research problems are now much harder and the amount of background material you have to understand is very big and the material is intrinsically difficult ,but don't lose hope . You could be smart enough to earn the nobel...

As far as I know , String theory is not a field theory . We just don't know what string theory is so we study it using tools that come from field theory like faddeev popov ghosts and gauge fixing and functional integration. Gravity ,being nonrenormalizable,can't be described by a quantum field...

Hi , I want to read the following paper : S. W. Hawking, \Breakdown of Predictability in Gravitational Collapse," Phys. Rev. D 14, 2460 (1976). But can't find a free version . It's not on arXiv so if someone can help me out , It would be appreciated . By the way ,Another paper that I need...

@WannabeNewton I think that it's better to reach the interesting topics quickly using the minimum required background . In electrodynamics , In my opinion , It's better to understand how maxwell equation can be derived from the principle of Einstein relativity by choosing a lagrangian that's...

So what do you think the most active area of beyond the standard model physics is ?

I recommend that you read boas mathematical methods and do all the exercises(You don't have to read all chapters) . Then , read through griffiths quantum mechanics and electrodynamics then perhaps you can read cohen tannoudje quantum mechanics and then peskin or srednicki quantum field theory ...

I meant physics beyond the standard model that's how to unify quantum mechanics and gravity

If you want to do fundamental physics then I think that the only option is string theory . Most research is done in string theory .All other approach are not well developed and can likely lead to blind ends Also string theory is not restricted . Ideas from string theory are applied to condensed...

Look at weinberg QFT , his chapter on scattering is clear and he treats the general situation in a concise manner , I think that you need to understand contour integration ,green functions and spherical harmonics to properly understand scattering . Also , L&L is very good

I actually meant to get a top score , I've actually downloaded a version of the physics and math test . The questions are not that hard . It's the type of problems that you find in undergraduate textbooks .I'm actually reading graduate level textbooks now

ZapperZ, Imagine that I can pass all the required GRE tests in physics/math but I don't hold a bachelor's degree in any field that requires math so all my knowledge come from self-study . Does this substitute for an undergraduate program ? I'm reading graduate textbooks in physics e.g jackson...

What's more difficult for you ? To apply mathematics to analyze a physical problem or to understand mathematics by itself ?

Sounds interesting . What mathematical knowledge required to be able to understand that paper ?

I've read that if one wants to quantize gravity , there must be a smallest length scale " The Planck length " . If I want to measure the position of a point particle then in conventional Quantum mechanics I'll find it at the point $(x,y,z)$ at some-time $t$ with an arbitrary momentum but this...

Apostol is the best calculus textbook I've found . Courant is also very good . I think that stewart-like calculus texts are good if some one wants to know how to apply calculus to standard problems but It doesn't give you a solid understanding of the concepts which is needed if you want to solve...
