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

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.

"most commonly" ..
Well. In quantum physics a good example might be the "schrödinger equation"? http://en.wikipedia.org/wiki/Schrödinger_equation

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.

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question.
Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point?
Lets call the point which connects the string and rod as P.
Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is
The second part of the problem is exactly why you get this affect.
And one more spoiler:
Let's declare that for the cylinder,
mass = M = 10 kg
Radius = R = 4 m
For the wall and the floor,
Friction coeff = ##\mu## = 0.5
For the hanging mass,
mass = m = 11 kg
First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on.
Force on the hanging mass
$$mg - T = ma$$
Force(Cylinder) on y
$$N_f + f_w - Mg = 0$$
Force(Cylinder) on x
$$T + f_f - N_w = Ma$$
