So I'm about to reapply to grad schools but one of my previous research advisors (I worked for him 3 years ago) will not write me LORs again. Thus, I will only have 1 LOR from a previous research advisor. I plan to get a new one from a prof I will start a research project with soon. For the 3rd...

So I learned way back in economics 101, that when it's more profitable to produce/provide service A rather than B, more people will jump on the A band wagon, until the supply of A increases to the point that the price of A is no longer greater than B. Why does this not apply for medicine? Is...

AdS/CFT has primarily focused on quark-gluon plasma, but I notice some people are trying to apply the idea to bound states such as baryons. How much progress has been made in this field? Is it possible for AdS/CFT to shed light on problems such as parton distribution functions and proton spin...
