Hi guys, I find it hard to decide what to work on. To give some background, I am a bachelor student and I want to work in theoretical research. I talked with a professor (he is the chief of the theory department) at my uni about this and he expects me to find a topic or an area of research for...

Hi! As the title suggests, I am searching for some good problem books with really challenging problems for classical physics, more precisely on the topics of electricity and elecromagnetism, geometrical optics and wave optics, thermodynamics and analytical mechanics. When I say challenging I...

Thanks a lot.

So, I'm now studying thermodynamics and our teacher proved some time ago the following mathematical result: If f(x,y,z)=0, then (∂x/∂y)z=1/(∂y/∂x)z But today he used this relation for a function of four variables. Does this result still hold, because I'm not really sure how to prove it. If...

First.

The title kind of says it all, but I'm searching for a textbook that has a heavy theoretical approach. Could someone help me with a recommendation?

This question is as dumb and simple as it can be: Why is the path difference 2dsinθ? Or better said: Why x-ray scatters like in the image? (Couldn't there be another scattering angle for both atoms other than θ?)

Radians are just real numbers. They are not a completely different unit of measurement like degrees.That's why radians were created: to express angles by real numbers. You can say that the units for frequency are rad/s as well as you can say they are 1/s or s-1. Also, it helps a lot to...

I'm trying to self-study general relativity, but I encounter a problem. I can easily understand the ideas and the results, but there are some things related to 4-d geometry that I can't find, like what are Christoffel symbols and how to solve the equation of a geodesic line. I searched for those...

As the title implies, I'm looking for books on non-euclidean geometry. I'm not looking for very advanced thing, more on some book with a good introduction to this topic.

I have a hard time understanding the variation of mass with velocity, more precisely the proof. In almost every material I've found, the author analyses 2 bodies colliding. The idea of looking at the collision is not hard to grasp and by considering one of the velocities equal zero, you get a...

Hi! I am physics passionate and I have always tackled a bit of this and a bit of that in other sciences. I have recently found out that there is something called forensic science (like in CSI stuff). No, seriously, I found out that this is a thing like two weeks ago, so I want to see what's with...

Homework Statement sin x = C*sin y Find y as a function of x for a given C>0. Homework Equations sin x = C*sin y The Attempt at a Solution This is not actually a problem from a book, but a problem I myself thought about. I was studying elastic collisions in SCM and I obtained 2 equations...

This is not a normal problem help topic. The difficulty I've encountered is in understanding an alternative solution. 1. Homework Statement In a real conductor, electrons (with mass m), conducted by external electric fields, constantly collide with defects and impurities within the conductor...

Homework Statement Let (an)n≥1 be a sequence with a1≥0 and an+1=an(an+4), n≥1. Compute limn→∞ (an)(1/(2n)). Homework Equations a1≥0 an+1=an(an+4), n≥1 L = limn→∞ (an)(1/(2n)) The Attempt at a Solution Firstly, I had tried to see if an can be expressed only in terms of a1, but I couldn't get...
