Suggestions for Fall math elective courses?

Click For Summary

Discussion Overview

The discussion revolves around suggestions for math elective courses suitable for a senior physics major preparing for graduate school. Participants share their opinions on various courses, considering their relevance to different fields within physics, including quantum mechanics, general relativity, and computational physics.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants emphasize the importance of linear algebra, particularly for its applications in quantum mechanics, suggesting it is essential for anyone pursuing that field.
  • Point-set topology is mentioned as potentially beneficial for theoretical physics, especially for those interested in string theory, though it is noted that many physicists may not require this knowledge.
  • Numerical analysis is recommended for those leaning towards experimental or computational physics, with some participants expressing uncertainty about its relevance to their own areas of focus.
  • Basic probability and statistics are considered fundamental and useful across various scientific disciplines, though opinions vary on their necessity for specific physics paths.
  • One participant requests clarification on the specific area of physics the original poster is interested in, indicating that course recommendations may depend on this focus.
  • There is a suggestion to take either probability/statistics or numerical analysis alongside linear algebra, highlighting the value of both in physics applications.
  • A participant shares their limited understanding of linear algebra and expresses a desire to deepen their knowledge in the course, particularly in relation to quantum mechanics.

Areas of Agreement / Disagreement

Participants generally agree on the importance of linear algebra for graduate studies in physics, but there is no consensus on the necessity or relevance of the other courses, as opinions vary based on individual interests and intended areas of study.

Contextual Notes

Some participants note that the relevance of certain courses may depend on specific fields within physics, indicating that the choice of electives could be influenced by the student's future academic and career goals.

I am a senior physics major and I have several electives (up to 2) to fill with math courses this Fall. I have previously taken:

Calculus 1-3 (Stewart)
Ordinary Differential Equations (Edwards and Penny)
Partial Differential Equations (Haberman)
Matrix Algebra
Parallel Processing

I am also required to take Mathematical Methods for Physicists and Engineers ( Matthews and Walker) in the Spring.

From the list below please tell me your likes or dislikes of the courses (if you have taken them) and how they contributed to your further studies (I am planning on graduate school in physics). Thanks for your time!

Possible Courses:


Probability and Statistics I - probability axioms and properties; conditional probability and independence; counting techniques; and discrete, continues, univariate, and multivariate random variables

Linear Algebra - theory of real vector spaces and linear transformations. Topics include vector spaces, inner product, norm, distance, subspaces, spanning sets, linear dependence and independence, bases, dimension, linear systems, coordinates, linear transformations, kernel, image, isomorphisms, inverse linear transformations, matrix representations of linear transformations, similarity, direct sums, and canonical forms.

Point Set Topology - open and closed sets, interior, closure, boundary, neighborhoods, continuous functions, separation and subspaces. Additional topics will be selected from compactness, connectedness and continua. (This has a prerequisite of Advanced Analysis but I spoke to the professor and he said not to worry about it. )

Numerical Analysis - Topics will be selected from error analysis, solving algebraic equations, interpolation, numerical differentiation and integration, methods for solving systems of equations, approximation theory, and initial value problems of ordinary differential equations.

Discrete Mathematics - Techniques and tools of reasoning, decision making and combinational problem solving. Topics include sets and logic, combinations, probability, relations and functions, Boolean properties and graph theory.


Note:
I will also be taking:
Intermediate Mechanics (Fowles & Cassidy)
Intermediate EM (Griffiths)
Medical Physics I
and possibly Statistical Thermodynamics (Callen ?)

If you do not already know linear algebra, you should take the course. It is useful for a lot of physics, most notably quantum mechanics where it is absolutely indispensable.

Point-set topology is a good place to start if you plan on getting into certain types of theory like string theory, but most physicists don't need to think about topology. Same and to a greater extent with discrete math.

Numerical analysis sounds like a good course to take if you plan on getting into experimental or (especially) computational physics. But this isn't what I do, so I'll let someone else make a recommendation here.

Basic probability and statistics can't hurt since these ideas are somewhat fundamental to science.
 
You say you're wanting to go to grad school in physics. Can you be somewhat more specific?? What kind of physics are you considering. The answer will depend on that.
For example, if you're going into quantum mechanics, then you absolutely need to take linear algebra. If you're interested in general relativity, then topology might be helpful. Etc.
 
My recommendation would be 1) Linear algebra and 2) Either probability/statistics or numerical analysis. I think both in 2) are really valuable for physics, but as electroweak pointed out, you should really take linear algebra if you haven't done already.
 
My experience with linear algebra is that I think I know what an operator is and that it corresponds to taking a measurement or change of state (vaguely, I have take a intro Quantum mechanics course last fall) so not very deep at all. So I will take that course.

I am leaning toward something related to quantum mechanics, experimental or computational (molecular/atomic/nuclear or possibly medical physics).

Thanks for the replies!
