How important is it for a physicist have an understanding of analysis?

AI Thread Summary
Understanding analysis is crucial for physicists, particularly in mathematically intensive fields like cosmology and quantum mechanics. A strong foundation in linear algebra and analysis, including real analysis, enhances comprehension of complex concepts such as Hilbert spaces in quantum mechanics. While the necessity of analysis varies depending on the specific area of physics, having at least an introductory course in real analysis is beneficial, as it aids in grasping the mathematics encountered in advanced studies.

It might be useful to know what kind of physics you're referring to.

For the sake of discussion, suppose my plan was to study cosmology or another very math-y field.

Well, as an example, quantum mechanics makes liberal use of Hilbert spaces, so strong backgrounds in linear algebra and analysis would be very useful there. It's hard to generalize (because it depends to strongly on what, specifically, you're studying), but having, at least, an introductory real analysis course under your belt would be very useful. At the very least, it would help you understand a lot of the other mathematics you'll be using.
 

Thread 'Applied Math PhD candidate but I hate group theory'

TL;DR Summary: I want to do a PhD in applied math but I hate group theory, is this a big problem? Hello, I am a second-year math and physics double major with a minor in data science. I just finished group theory (today actually), and it was my least favorite class in all of university so far. It doesn't interest me, and I am also very bad at it compared to other math courses I have done. The other courses I have done are calculus I-III, ODEs, Linear Algebra, and Prob/Stats. Is it a...

Thread 'Where did all the “fundamentals-deepening” master’s programs go?'

I’ve been looking through the curricula of several European theoretical/mathematical physics MSc programs (ETH, Oxford, Cambridge, LMU, ENS Paris, etc), and I’m struck by how little emphasis they place on advanced fundamental courses. Nearly everything seems to be research-adjacent: string theory, quantum field theory, quantum optics, cosmology, soft matter physics, black hole radiation, etc. What I don’t see are the kinds of “second-pass fundamentals” I was hoping for, things like...
