AI Thread Summary
To effectively learn physics, especially with an interest in quantum physics, a solid foundation in mathematics, particularly calculus and linear algebra, is essential. Engaging with real-world experiences enhances understanding and intuition in physics. For those looking to study without incurring costs, utilizing library resources and textbooks is recommended. Pursuing a dual major in Mechanical Engineering and Physics is a strategic choice, as it offers better employment prospects compared to a standalone physics degree, which is more suited for those aiming for academia or teaching.

Best Way to learn physics?!?

I have taken honors physics and AP physics in high school (although we didn't do much in AP) and Calc 1. Most of physics really interests me. I'd love to learn quantum physics (I'm reading a book on it) but I know there is a lot of math to learn first. So what's the best way to learn as much physics as I can?

Currently I'm enrolled to major in Mechanical Engineering but I kinda want to dual major with Physics.

Pretty much just tell me or any general person how to learn physics. Preferably for free.

Thanks!

As good ol' Einstein once said, "physics is just a refinement of everyday thinking". So be sure to get out there in the world and just experience it. :) Developing intuition is vital. Quantum isn't too bad once you've got the linguistic tools of calculus and linear algebra under your belt. Also, I'd say you have a good choice in majors as far as future employment is concerned. Majoring in just physics is something I wouldn't suggest to anyone who isn't interested in academia or teaching. I had to learn that the hard way.
 


The part of the question where it says "preferably for free" made me think: Use the books at the library.
 
I graduated with a BSc in Physics in 2020. Since there were limited opportunities in my country (mostly teaching), I decided to improve my programming skills and began working in IT, first as a software engineer and later as a quality assurance engineer, where I’ve now spent about 3 years. While this career path has provided financial stability, I’ve realized that my excitement and passion aren’t really there, unlike what I felt when studying or doing research in physics. Working in IT...
Hello, I’m an undergraduate student pursuing degrees in both computer science and physics. I was wondering if anyone here has graduated with these degrees and applied to a physics graduate program. I’m curious about how graduate programs evaluated your applications. In addition, if I’m interested in doing research in quantum fields related to materials or computational physics, what kinds of undergraduate research experiences would be most valuable?
