Programs Is it advisable to take 3rd Bachelors program: BS Mathematics aft double major?

AI Thread Summary
The discussion centers on the advisability of pursuing a third Bachelor's degree in Mathematics after completing a double major in Biotechnology and Chemistry, particularly for a student interested in quantum chemistry. The student expresses dissatisfaction with biotechnology and a desire to transition into quantum chemistry, highlighting a perceived lack of mathematical knowledge necessary for this field. Concerns are raised about the feasibility of studying mathematics while working, as well as the extended time commitment required for another degree. Responses suggest that a full mathematics degree may not be necessary for success in quantum mechanics at the undergraduate level, emphasizing that foundational knowledge in calculus, linear algebra, and differential equations can be self-studied. Additionally, it is noted that many calculations in chemistry are computational rather than analytical, indicating that practical skills and self-directed learning may suffice for entering the field of quantum chemistry.

Chemists/Physicists: Is it advisable to take 3rd Bachelors program: BS Mathematics after first Double Major?

Well, my reason is that I ended up hating biotechnology (biochem in particular) and I'd like to see myself doing quantum chemistry (I'm a 5th year student of a Bachelor's program in Biotech and Chemistry). Can I take a mathematics degree while working? I am not quite familiar with the work of Chemists field/lab because I've not yet enrolled my On the job training course, so my question is: can you squeeze working while studying math?

I'm really quite confused because I finally found the field that I see myself in, however I know that I lack the knowledge in math to proceed to higher quantum chemistry.

As a fifth year student, I cannot take electives or minors in mathematics.

You do realize that if you take another math major, then you will have to stay in school for quite some extra time. No?

I don't think you need all that much math to succeed in quantum mechanics (on an undergrad level). You need calculus, linear algebra, and some DE's. These are topics that you can self-study...
 
While it is completely good to have a strong basis in differential equations, and linear algebra most of the calculations you do will be computational. Chemistry is about reactions so there will be statistical mechanics and simulations since it's pretty absurd to calculate the perturbations of 6 different wave functions on a hydrogen atom using analytic methods.

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.
