Math for Astrophysics & Quantum Physics: A Beginner's Guide

AI Thread Summary
Math is essential in astrophysics and quantum physics, with calculus and linear algebra being the primary tools used. The Schrödinger equation is highlighted as a key example in quantum physics. While self-teaching physics is possible, taking classes is recommended for better understanding and support from experts. Having access to an instructor can help resolve difficulties that arise during study. Overall, structured learning is beneficial for grasping complex concepts in these scientific fields.

math is must commonly used in astrophysics and quantum physics? This might be a stupid question. Not sure

Calculus (taking derivatives, integrating, solving ordinary and partial differential equations) and linear algebra (notions of operators, eigenvalues and eigenvectors, basis, spaces, etc) are the main math tools used in these fields.
 
One other question, Can a person teach them selves physics or is it preferred to take a class?

Classes are great because you have an expert available for when you get stuck. Getting stuck on a concept when you are on your own can be a tremendous problem with no support.

:biggrin: But that's why we have you Pengwuino! :biggrin:

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
