What Math Do You Need for Theoretical Physics?

Click For Summary
SUMMARY

The discussion centers on the mathematical prerequisites for studying theoretical physics. The participant expresses a desire to transition from a background in college algebra to more advanced mathematics necessary for physics. Key recommendations include taking courses in calculus, linear algebra, and differential equations, which are essential for understanding theoretical physics concepts. The participant also inquires about the relevance of chemistry courses and the potential use of online resources like Khan Academy for self-study.

PREREQUISITES
  • College Algebra
  • Calculus (single and multivariable)
  • Linear Algebra
  • Differential Equations
NEXT STEPS
  • Research "Calculus for Physics" courses available online
  • Explore "Linear Algebra" resources on Khan Academy
  • Study "Differential Equations" through MIT OpenCourseWare
  • Investigate introductory "Chemistry for Physics" courses
USEFUL FOR

Individuals interested in transitioning to theoretical physics, self-learners seeking to strengthen their mathematical foundation, and those looking to utilize online educational platforms for physics and mathematics studies.

Hello.

I have been a member on this forum for quite some time and I came here because I've always had an interest in science, particularly physics. When I was in Junior High, I did very well in my science class but by the time I got to college, I wanted to make money. However, I realized that having a job as a physicist was not going to cut it, so I took the other path and now I am financially secured thanks to specializing in online marketing.

Now that I have some free time, I decided to look into physics, specifically, theoretical physics because I've always had a fascination within that field. In the past, whenever I would go to a bookstore and check out the physics section, I would randomly select a book on the subject and I would see those mind-bogglingly complicated physics equations stare angrily back at me. Many years ago, I used to get intimidated by them, but now, I've changed my atititude to the point where I don't let it bother me anymore, thinking positive by saying to those physics equations, "Some day, you and I are going to be good friends, you'll see". I'm doing this for me, for my own enlightenment.

Anyway, I understand that there is a lot of math involved in science, especially physics and the closest level of mathematics that I reached was college algebra.

What other math courses must I take prior to introductory physics? Do I need to take a course in chemistry too? What is the order in terms of what math classes I should take in regards to my journey to eventually learning physics? What about taking online courses at the Khan Academy website? Thanks in advance! :)

That's okay, I have some time, thanks again! :wink:
 
TL;DR: How can I begin to gain an understanding of astronomy? Hello there, and thank you in advance to anyone that might answer this. I'm sorry if this is the wrong place to post a question like this, as I am new to this website and also very nervous about making a post that others might see/reply to. I am a freshman in high school and I am interested in astronomy. I want to learn about space, but I am not quite sure where to begin. Is there anything that I can do to seriously expand my...
