AI Thread Summary
The discussion revolves around the various subfields of physics and seeks clarification on specific areas. High energy physics is identified as a distinct branch, separate from classical mechanics, electricity and magnetism, light and optics, and modern physics. Quantum mechanics is linked to advanced topics such as quantum computers, quantum field theory, string theory, and unified field theory. Condensed matter physics is also mentioned as a significant area of study. Participants are encouraged to explore resources like the American Physical Society's list of units and other online materials to gain a deeper understanding of these subfields.

Streams in physics??

I want to learn what different types of physics are out there

In high school I learned
  • classical mechanics
  • electricity magnitism
  • light & optics
  • modern physics

But what is high energy physics and which group of list above does it belong to??
and is quantum mechanics related to quantum computers, quantum field theory, string theory, unified field theory?
What is condensed matter physics?


...sorry I am just curious

Some of the other hits may also be useful.

Also note the list of "units" of the American Physical Society:

Each unit's website has a brief description of the areas that it covers.

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...
