Courses Quantum Mechanics Math Course

AI Thread Summary
The discussion centers on the choice between enrolling in a Probability course or an advanced Differential Equations course for the upcoming semester. The Probability course covers fundamental concepts such as discrete and continuous sample spaces, conditional probability, and various distributions, while the Differential Equations course focuses on boundary value problems, including the Shooting Method, Green's Functions, and Sturm-Liouville Problems, with applications to quantum mechanics. Participants express a preference for the Differential Equations course, arguing that it offers more practical applications in fields like quantum mechanics and provides a stronger foundation for further studies. The consensus suggests that a solid understanding of differential equations is more beneficial than probability theory in this context.

Sorry I keep posting about this. I had settled on Probability (Probability in discrete and continuous sample spaces; conditional probability; counting techniques; probability functions; binomial, Poisson, normal distributions; and transformations of variables.) based off of previous answers to posts on here, but my differential equations professor this semester just told the class today and sent us an email about a directed study class he is running on advanced differential equations next semester. The description is "A focus on boundary value problems with topics such as the Shooting Method, Green's Functions, Sturm-Liouville Problems, and the Contraction Mapping Theorem. Phase portraits with an emphasis on limit cycles will be explored." It sounds really interesting and I have heard references to Green's Functions and Sturm-Liouville equations when reading about quantum mechanics, so I was wondering whether anyone had any advice on whether Probability is more useful for quantum mechanics or the advanced differential equations course? (I only have room for one of the courses next semester otherwise I would take both.) Thank you so very much for any advice!

In my opinion the course about differential equations is of greater use. The step from a position of a firm knowledge about analysis towards probability theory is far smaller than the other way around.
 
Definitely differential equations.
 
Hey, I am Andreas from Germany. I am currently 35 years old and I want to relearn math and physics. This is not one of these regular questions when it comes to this matter. So... I am very realistic about it. I know that there are severe contraints when it comes to selfstudy compared to a regular school and/or university (structure, peers, teachers, learning groups, tests, access to papers and so on) . I will never get a job in this field and I will never be taken serious by "real"...
Yesterday, 9/5/2025, when I was surfing, I found an article The Schwarzschild solution contains three problems, which can be easily solved - Journal of King Saud University - Science ABUNDANCE ESTIMATION IN AN ARID ENVIRONMENT https://jksus.org/the-schwarzschild-solution-contains-three-problems-which-can-be-easily-solved/ that has the derivation of a line element as a corrected version of the Schwarzschild solution to Einstein’s field equation. This article's date received is 2022-11-15...
