Discussion Overview
The discussion revolves around selecting a 4000-level math course for a physics major with a math minor. Participants explore various course options, including their relevance to graduate school preparation and practical applications in physics and related fields.
Discussion Character
- Exploratory
- Debate/contested
- Technical explanation
Main Points Raised
- Some participants express a preference for Nonlinear Dynamics and Chaos, citing its engaging nature and relevance to their future studies.
- Introduction to Stochastic Processes is recommended by some for its practical applications in modeling real-world situations, particularly involving Markov processes.
- Partial Differential Equations (PDE) is mentioned as useful, especially for those already taking an introductory course in the subject.
- Advanced Abstract Algebra, Topology, Differential Geometry, Integral Equations, and Number Theory are suggested by one participant as potential options for graduate school preparation.
- Concerns are raised about the theoretical nature of the PDE course, with some suggesting it may not be as applicable to the physics major compared to other courses.
- Numerical Analysis is noted as a useful skill, although its relevance to the discussion is less emphasized.
- One participant questions the utility of the Mathematics of Financial Derivatives course for future financial work.
- Real Analysis is mentioned as a challenging course, with mixed opinions on its applicability to physics.
Areas of Agreement / Disagreement
Participants do not reach a consensus on which course is the best choice. Multiple competing views exist regarding the relevance and utility of the various courses discussed.
Contextual Notes
Some participants note that the introductory courses may not cover advanced topics such as Green's functions or convergence of Fourier series, which could affect the perceived utility of the courses for graduate studies.
Who May Find This Useful
Students in physics or mathematics considering advanced coursework and those interested in graduate school preparation may find this discussion relevant.

My suggestion is MATH 4355: Mathematics of Signal Representation. Why? Because I think it will pack the most punch for the money. The idea of a signal is incredibly useful and unifying, and you don't really have go into full rigor to understand things conceptually. I was lucky to learn these ideas outside of class early on and I can hardly think of any more useful in understanding physics in general. Think of just a few examples of physical things that are signals:
position of particle(s) as function of time
string
membrane
sound field
electromagnetic field
voltage as function of time at a point
temperature field
any time series data
A few places where these ideas pop up:
Heisenberg uncertainty principle (a property of the Fourier transform which applies to any signal)
decomposition of string, membrane, sound field, quantum wavefunction, or EM field into modes
condensed matter (phonons)
electronics/communications
spectroscopy
imaging (CT scans, holography, etc)
system identification and control
general interpretation and storage of data
As far as I can tell, every branch of physics uses these ideas in a nontrivial way. In math, this ties together linear algebra, functional analysis, and ODEs/PDEs.
I don't see how the other courses could be this useful. Things like real analysis and (point-set) topology are good to know, but you'll get very little working knowledge out of the entire semester- mainly you'll learn how to make what you already know rigorous. If you'll immediately be doing research in GR you should probably take differential geometry but otherwise it'll give you little milage. The linear algebra and differential equations courses are probably useful, but I think the signals course would be better- for example, it will make those courses easier to learn on your own later. The nonlinear dynamics course would also be useful, but I still think the signals would be better- for NLD you could pick up a copy of Strogatz and learn it on your own. The abstract algebra and number theory courses might be fun (if you like that sort of thing) but are more or less useless for physics.
I don't know much about the financial stuff or how you might use it, so I can't comment there. Maybe one of those courses would be worth more to you than my suggestion- I don't know.
