abs(x)^2 = x^2

Thanks for the comment! I searched for all the books in my university's library and only the book by Friedberg wasn't found :) I guess I'll take a look today.

A lot of condensed matter requires some knowledge of optics. I actually think it's weird that you're studying physics but have had no optics, because it's a first step to quantum mechanics. I don't know what courses on math you've had, but if you've had calculus up to and including the...

Optics is doable at the end of your first year, that's when my university teaches it. Fibre optics will probably require knowledge of optics. Material science is probably a prerequisite for material processing as well. I would advise optics and either fibre optics or material science. It truly...

My university doesn't offer many courses on theoretical physics (I'm studying applied physics), but because I might want to get my masters degree in theoretical physics, I want to read into some of the math and physics. What books would you recommend to a student who has had linear algebra...

In the limiting case the two charges will be at one point, resembling the field of a single charge (with the magnitude of both charges combined.) So, when you move two like charges closer to each other, the equipotential lines will start to look more and more like that of a single charge.

De broglie says that the rules for wavelengths for photons are valid for other matter as well.

Hi! So far I think your video's are very nice, yet I have a question about the 4th video. When discussing balls in a discrete metric space, you say that only {c} is contained in the ball if r is less than or equal to 1. Now, there are two possibilities in my head. The first is that this is a...

I think it would be a better idea to study electromagnetism first

Fusion is a topic mostly studied by plasma physicists and not by particle physicists

My study uses Freidberg's Plasma physics and fusion energy for it's courses on fusion.

There's a coil inside a metal detector which emits EM-waves. If there's a metal nearby, the EM-waves induce currents inside that metal. Because currents are a source of magnetism, an EM wave will also be emitted by the metal. Both waves are detected by a second coil inside the metal detector...

1. Get your graphing calculator. 2. Y1=5^-x, Y2=log(x) 3. Plot and use the intersect function of your calculator.

You need to solve them numerically. Topics like this one belong in the homework forums.

It is arbitrary; b can be pi+k*2*pi, where k is an integer.
