AI Thread Summary
To learn Quantum Physics effectively, a solid foundation in classical physics and mathematics is essential. Beginners should start with a calculus-based introductory physics textbook, such as Halliday, Resnick, and Walker's Fundamentals of Physics, which covers classical mechanics and electromagnetism. It is recommended to complete courses in calculus, differential equations, and linear algebra before advancing to quantum mechanics. A broader understanding of topics like electromagnetism, relativity, and thermodynamics will also be beneficial. Establishing a strong grasp of these subjects will prepare learners for the complexities of high-level Quantum Physics.

Summary: Wish to learn Physics in a bid to learn and understand more about Quantum Physics.

Hi! I have a background in college Mathematics. I wish to learn Physics with a goal of reaching high-level Quantum Physics understanding. It'll probably take a few years or so. I was hoping anyone could tell me where I should begin, please? Is it as easy as grabbing a high school physics textbook and start from there?

Thank you.

First, do you want to concentrate on theory? If not, then you need some formal physics educational process to get access to a lab.

Depending on your current level of mathematics you have a couple of options. You could prepare the ground with some university-level classical mechanics and then go straight to QM and see what you make of it. Jumping straight into QM might be too much. There are people who post on here who have done that, but IMO they seem to get confused by just about everything! You are better getting some experience and grounding in physics and applied mathematics generally before tackling QM.

Or, you could spend more time on covering a wider physics syllabus. Especially EM, Relativity, Cosmology, Thermodynamics etc.

There are recommendations for lots of introductory QM textbooks on here. For classical mechanics, I like Kleppner and Kolenkow, which has a strong, algebraic approach. The "plug and chug" approach is not going to get you very far when you hit QM.

Can you be more specific? Have you taken calculus, differential equations, and linear algebra?

If you haven't taken any physics, I'd start with a calculus-based intro physics textbook.

"Quantum Physics" is a vague term that potentially encompasses a huge range of physics, both theoretical and experimental. It would help if you can tell us about some specific topics that you've heard or read about, that have piqued your interest, and want to study deeply.

In the US, people usually start serious formal study of physics at the beginning of undergraduate or late in secondary school ("high school") using a textbook such as Halliday, Resnick and Walker's Fundamentals of Physics. There are other similar books; this is simply one of the commonly-used ones.

The first course is usually two semesters focusing on classical mechanics and electromagnetism. At some schools, there is a third semester that focuses on "modern physics" with an introduction to relativity, quantum mechanics and their applications. At other schools, there is a separate "introductory modern physics" course.

The Halliday/Resnick/Walker book comes in two versions, the "normal" version for a two-semester course focusing on classical physics, and an "extended" version for a three-semester course that includes modern physics. There are also some "intro modern physics" books for a separate course. I used Beiser's Concepts of Modern Physics for many years (late 1980s until early 2000s), but it appears to be out of print, or at least hasn't been updated recently.

These courses assume a basic knowledge of single-variable calculus (derivatives and integrals), but you don't need to complete a full sequence of calculus courses in advance. At many schools, the first two semesters of physics are designed so that students can take the first two semesters of calculus alongside them.

After the introductory course(s), undergraduate students take "upper division" courses in classical mechanics, electromagnetism, quantum mechanics, etc. These require a full calculus sequence (single- and multi-variable calculus), plus ordinary differential equations and some linear algebra.

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...
After a year of thought, I decided to adjust my ratio for applying the US/EU(+UK) schools. I mostly focused on the US schools before, but things are getting complex and I found out that Europe is also a good place to study. I found some institutes that have professors with similar interests. But gaining the information is much harder than US schools (like you have to contact professors in advance etc). For your information, I have B.S. in engineering (low GPA: 3.2/4.0) in Asia - one SCI...
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?
