Huge respect for the work you must put into everything your doing between going to classes, work, living, staying healthy you somehow fit editing in somewhere. But when you enjoy all of the stuff you do, like really enjoy it, it all seems worth it. I'm just starting my physics major I got 2.5 years into a material science engineering major and realized I want to major in physics because what better way to learn how materials work then learn how the world works. Plus physics has always been a passion of mine. I've never really been good at math, I'm like average level for engineering, and I'm super worried about the classes to come but I guess the only way is to struggle through it. Great channel keep it up!

4:28 The magnetic quantum number comes from deriving the function for Phi (the azimuthal angle) and both the orbital angular momentum function and the limits of the magnetic quantum number come from deriving the function for Theta (the polar angle). These two functions are the "spherical harmonics," and their product gives us the spherical component of the wave function (the radial component is the other, and we get the principal quantum number, "n," from this. You're welcome.

It’s not as much memorization as you think. This is because you use these formulas and theorems so often that it becomes second nature. The real challenge in physics is thinking on your feet. Derive as you go. Memorization of formulas is nothing to be concerned about.

Hi Andrew, I'm hoping to declare as a Physics major with a Comp Sci minor pretty soon. Can you speak on the programming courses that you've taken? How many you've taken, which languages you have had to learn, how much programming experience you had prior to taking these courses/starting university, and just how much application your programming courses have had on the physics that you have learned so far. As in, have you had to use programming to do physics modeling, solve problems, etc etc..

PierreAlvinGo I’m a physics major with CS minor. At my university my CS1 course was in C and CS2 was in Java. I’m doing undergrad research in physics though and I’ve had to learn Python for data analysis. This is the language we do everything in and to be honest my programming classes haven’t helped me very much with what I’ve had to do with my physics programming. I’ve also developed a few different kind of models and tested them in python and Julia which again my computer science classes didn’t really help me with. Talking with my peers, I’ve heard the same response from them. Hope this helps!

MrLethalShots my university first of all requires independent research to graduate, which I think sets the tone for students and professors at the getgo to be accommodating with research. The physics faculty are constantly holding colloquium and advertising their research to us because they want undergrads to work with them. So you just have to ask. Most of the time they can find something for you to do if you don’t have the classes to help them yet. They might give you papers to read or check their papers for grammar menial things until you know what’s happening. Or if you already have skills like programming you can usually jump right into doing data analysis stuff

Hi, my programming experience has been unorthodox to say the least. I first learned to code in python through my research internship. I then took a course in computational physics, which I did using python, and am now taking a course in C++. Learning how to code has helped a huge amount when it comes to wanting to plot out what something looks like, or solve problems that are too hard on paper.

PierreAlvinGo Just another tidbit, I’m a sophomore physics major and computer science minor. I’ve taken courses involving Python, Java, C++ and a few others like html and JavaScript. Honestly, I primarily use Python for physics and prefer it to most of the other languages I have learned as well. I came into university only knowing html and JavaScript, the rest was taught along the way. My university as a whole course dedicated to teaching you to program in Python and using it to solve problems and run simulations such as random walks and processes. I actually recently decided to discontinue the computer science minor in favor of taking more physics courses, getting more involved in research (I’ll be undertaking a second research project) and getting more experience with my “physics” skills.

Why is angular momentum so important in quantum mechanics? The textbook and your exams seem to go into great detail about the topic. All I can think about is the spin of the particles and their motion around an atom, which doesn't seem to be as important as your textbooks make it. Is there a deeper meaning?

There are certain quantities that you can't measure simultaneously (like position and momentum, ergo uncertainty principle). So when you come across something that tells you mathematically that it's possible with something else (like orbital angular momentum and spin in some direction), it's worth trying to find a state to put the system in that would allow you to do so. This is like maximizing the number of measurements you can make on a system in one experiment. There are very few quantities that allow you to do this, and finding out the properties of the operators that give these values is worth exploring. I hope this helps.
