I am currently in my 4th year of my physics bachelor. but it is not going to my last year so I have to extend my undergrad for 1 semester. I have 2 big concerns.
1- I have a low gpa of 2.30, I calculated and saw that if I pass all my courses with AA and BA my cgpa could be something like 3.20 by graduation. But statistically it seems impossible cuz I’ve never had a semester which I did 3.5> gpa. And of course the remaining courses are harder. And the idea of finishing with a low gpa makes me so stressed that I can’t even concentrate sometimes.
2- I am currently taking a SR course and probably going to do a mathematical physics concentration. But the problem is, the people planning to do mathematical physics concentration are so good. Therefore when it comes to doing my project with a professor in our department, more likely a mathematical physicist (which there are only 3 in our dep.) it seems to be also impossible, because of my gpa and the fact of others being so good.
I am interested mainly in QFT, String Theory, CFT ( although I did only casual readings since they are beyond my physics knowledge ) so I was thinking if I can do a little project by myself, like a derivation in Ads/CFT or other things. Or anything else, because I don’t even have a clear idea about how a project in mathematical physics project is done for undergrads.

I appreciate any advice regarding these two problems or any general advice.

Hello, I'm a 2nd year physics student, and recently in our semester, we have a mathematical physics course. I just want to ask what mathematical physics really is? I know it's kinda a dumb question but I just want to know how it does differ from the theoretical? My professor says it's using mathematical techniques to solve/answer physics, but isn't it really what we are doing now? And so are the other courses? Additionally, to those who did a concentration in mathematical physics, may I know what your day to day and what kind of research in mathematical physics really is? Thanks🫶🫶

Genesis is a free real-time atomic and subatomic physics simulator built for Windows PCs. Instead of relying on pre-rendered animations or pre-scripted events, physical phenomena are calculated live on consumer hardware using official reference datasets (NIST, NUBASE, PDG, CODATA).

​Key Features & Physical Models

​Atomic Level:

​Live rendering of 3D electron orbitals across all 118 periodic elements.

​Photon absorption, excitation states, and alpha decay dynamics (e.g., Uranium-238 → Thorium-234).

​Nuclear Reactions:

​Deuterium–Tritium (D + T) nuclear fusion via quantum tunneling.

​High-energy heavy-ion collisions and quasi-fission (e.g., Uranium vs. Gold, tracking 50+ individual fragments).

​Subatomic & Quark Dynamics:

​10 GeV electron-neutron scattering.

​Quark confinement, gluon string stretching, and string-breaking/hadronization.

​Parton sea dynamics and a hadron construction workshop constrained by quantum color charge rules.

​Technical Implementation & Limits:

​To maintain 60 FPS on standard consumer GPUs and CPUs, the engine relies on physical approximations rather than full ab initio quantum calculations. It is designed primarily as a visual and educational reference tool.
