Hello Everyone, I want to know if it's a good time to study string theory from the basics? Or is it wiser to wait till next year, after the 2015 LHC run, if indeed we find any evidence for it? I have done a course in mathematical physics, classical and quantum field theory, electrodynamics and...

Is there any difference between Hamiltonian operator and E? Or do we describe H as an operation that is performed over (psi) to give us E as a function of (psi)??

Dude if u draw the fbd of the particle at some general theta with the vertical/horizontal(whichever u prefer); try equating the the normal contact force component to zero AND resolving the component of mg along the radius of the circle, that component will provide the centripetal force at that...
