QFT & GR: Essential to Learn Before String Theory?

AI Thread Summary
Understanding Quantum Field Theory (QFT) and General Relativity (GR) is crucial before delving into string theory. QFT is particularly emphasized as essential due to its foundational role in the mathematical framework of string theory. While both QFT and GR contribute to the language and concepts used in string theory, a solid grasp of QFT is deemed more critical. GR, while useful, is secondary in importance compared to the necessity of mastering QFT for a comprehensive understanding of string theory.

How essential is it to know QFT and/or GR before learning string theory?

Is QFT more important or both equally as important?

Well given that string theory uses language from both areas, I'd say it was very important to have a working knowledge of GR and QFT before trying to learn that mathematics of string theory.
 
QFT for certain, GR is useful.
 

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...

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...
