As a year II physics major, when should I take linear algebra

Click For Summary

Discussion Overview

The discussion revolves around the timing and necessity of taking linear algebra for physics majors, particularly in relation to other mathematics courses such as calculus and differential equations. Participants share their experiences and opinions on when it is most beneficial to take linear algebra in the context of pursuing advanced physics studies.

Discussion Character

  • Debate/contested
  • Homework-related
  • Conceptual clarification

Main Points Raised

  • One participant expresses uncertainty about when to take linear algebra, noting that their adviser suggested it could be delayed, despite feeling it is necessary for graduate-level physics.
  • Another participant states that at their university, linear algebra is typically taken in the first semester of the first year, emphasizing its importance for physicists.
  • A participant reiterates the need for linear algebra, questioning how one could solve multivariate differential equations without it, given its prevalence in physics.
  • One contributor compares the necessity of linear algebra to the impracticality of filling a bathtub with a teaspoon, suggesting that advanced physics without it is highly challenging.
  • Another participant recommends taking linear algebra alongside other math courses, suggesting that it should be completed before the third year when more physics classes are taken.
  • One participant notes that while linear algebra is integrated into fundamental physics courses, it is often not taken until the second year, particularly for those with a heavy course load.

Areas of Agreement / Disagreement

Participants express differing views on the timing of taking linear algebra, with some advocating for an earlier completion while others suggest it can be postponed. There is no consensus on a definitive timeline for when it should be taken.

Contextual Notes

Some participants mention that linear algebra is not a requirement at their university, which may influence their perspectives on its necessity and timing. Additionally, the integration of linear algebra concepts into other courses is noted, but the extent of this integration varies among institutions.

After seeing so much higher-level physics and proofing for special relativity, I imagine I'll need to take this at some point to continue do grad-level physics. I'm taking calc III at the start of year two, and then on to diff eq. When should I take linear algebra in that case? My adviser seemed to think I could wait to take it - and it's not even a requirement at my university's program - but seeing late classes convinces me that I need to take it at some point.

At my university, physics students take linear algebra in their first semester of their first year together with the mathematic students. I can't imagine how a physicist doesn't use linear algebra.

How did you manage to solve multivariate differential equation systems? With vectors, matrices and tensors basically everywhere in physics, I cannot understand the advice you've been given.

Ar my university linear algebra is among the courses students take first. Trying to do any kind of advanced physics without linear algebra is like trying to fill a bathtub from a lake using only a teaspoon.
 
Take linear algebra with either of the other math classes. You'll probably be taking a lot of your physics classes your 3rd year, so take it before then.

I guess it's because this sort of stuff kind of gets integrated into our fundamental physics courses (the major-specific ones), as well as the calcs. Linear algebra is not usually taken until at least year 2 in my university it seems, unless you're an already-started math major. I know a lot of first-semester sophomores take it with multivariable, but I'll end up doing it with diff eq. My schedule is a little too loaded to take another math course.
