AI Thread Summary
The discussion focuses on selecting the right discipline for postgraduate studies that bridge mathematics and physics. The individual seeks a mathematical field that can accurately describe the relationship between mathematical theories and physical reality, citing the Rayleigh–Jeans law as an example of a mathematical concept that failed when applied to nature. Participants suggest exploring areas such as mathematical physics or theoretical physics, recommending that the individual research universities offering programs in these fields to find suitable options. The emphasis is on finding a discipline that can effectively distinguish between mathematical correctness and physical applicability.

Hi professionals , kindly I just want someone help me to choice the right Discipline for my post graduate study , I want to study in a mathematical field that enable me to describe the relations between the mathematics and physics . or in other words , the relations between mathematics and the existence .

any help will be appreciated .

Just for illustration , as you know that ( Rayleigh–Jeans law ) was seems mathematically correct , but when scientists applied that law in the nature it was incorrect !

so , what's the kind of math that enable us to distinguish between what's correct in mathematics and what's correct in the nature ?
 
Sounds like mathematical physics or theoretical physics...see what universities that might interest you offer in those areas.
 
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...
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...
