The Schrödinger equation is just another way of writing the conservation of energy, right? So how can you use it to find the quantum wavefunction? I mean in every example I've seen the wavefunction is calculated using sines and cosines so I don't see how you can use the Schrödinger equation to fi...

The only quantity after doing Feynman path integral evaluation is the propagator which is used to compute different observable. The paths of FPI don't appear anywhere in calculation of observable moreoever lots of irritation/paradoxes arise when one takes the path of FPI literally.

Look I am not asking too many questions and the questions listed below are just interlinked. For circular motion to happen we need a centripetal force or acceleration i.e. a force perpendicular to the direction of motion at all instants. So without any perpendicular component of force circular mo...

In Griffith's Electrodynamics, he asks what changes Maxwell's equations must accommodate if there exist magnetic monopoles. Now, it is clear to me that the Gauss Law and Ampere's Law must be left untouched. I also understand why the divergence of $\overrightarrow{B}$ should be $\alpha_{0}\rho_{m}...

We see an object when light from a source strikes the object and then reaches our eyes. How does light which is an electromagnetic wave gets encoded with the information about the object? Does the individual photons get encoded with this information or is it the wave nature of light which gets mo...
