Hello!
This spring i am going to do my master in some area of physics, something in theoretical physics/mathematical physics.
I have also taken many particle physics, space physics, and pure math courses.
The mathematics in physics like quantum mechanics and electrodynamics is more beautiful...
The conventional picture
We often describe two perspectives of infalling matter:
Outside observers see the object asymptotically approach but never cross the horizon, with signals becoming increasingly redshifted
The infalling object supposedly experiences a finite proper time to cross the...
I’m trying to keep a master list of all the theoretical “things” in physics that were once postulated to exist but probably don’t, like magnetic monopoles. Could anyone help me out?
So I was always wondering what a gluon computer (a computer using gluons instead of electrons or photons for the computing medium) would be like. There is absolutely NO literature anywhere online for it and the only mention is a brief card (with no description) in a sci-fi board game.
People...
I was watching a video on YouTube and while the channel is very credible; it said the often-believed-erroneous-belief that quantum entanglement can allow FTL travel or communication.
I left a respectful comment saying that this is incorrect but many other people actually do believe QE is FTL...
So, I am going into my second year in my physics-math double major. For our program, not much specialized math is specifically needed. I love theoretical high energy physics, have been attending seminars in institutes, and been trying to do some reading on my own (it is hard without the math...
Hi guys,
I recently graduated Cornell University with as a math major with physics concentration and got accepted into the mathematical physics masters at the University of Edinburgh (UoE) and the theoretical physics masters at King's College London (KCL). I wish to pursue a PhD in (possibly)...
Hi, I am a physics-mathematics double major and will most likely be going into theoretical high energy physics or mathematical physics for my PhD.
Considering the recent developments in AI, and how it is predicted to cause drastic changes in a lot of fields and job markets, do you think there...
This is just meant to be a subtle energy releaser as I feel pent up about this situation.
I have always been an A+ (B at my lowest) student and going into my harder physics classes has been proven a bit more difficult for me to adjust. I am retaking theoretical physics as I withdrew last...
In Star Trek, they mention a Chromo-electric pulse and Chromo-electric force field. I know chromo-electric fields hold the nuclear force together with gluons but could a highly advanced civilization use chromo-electric fields for weapons or protection?
I watch John Michael Godier on YouTube. He is a futurist and makes fantastic videos where he speculates on many things. Todays video was about primordial black holes and he speculated about Planet 9 not being visible because it may actually be a black hole born in the dawn of the universe. He...
Hi,
I am pursuing a master's in theoretical physics and applied maths and now I need to start working on a research project. It has been so tough to decide the topic as I currently don't feel ready to commit to one particular research area. Based on the modules I have taken so far, I do get...

Dear members of the forum,
I'm currently in Grade 11, seeking insights on...
I am planning on pursing a Phd in Theoretical physics or Mathematical Physics in the next several years. My main motivation is doing research when it comes to grand unified theory. What areas of research (within that umbrella, in a theoretical sense) should I start looking into that are at the...
I'm a physics undergrad student in Brazil and I'm about to finish my sophmore year. I'm really interested in computational and theoretical physics and I'm currently in the beginning of this year long research project with a professor in my university on the study of the 3+1 spacetime split of...
Hello everyone,
I've been grappling with a concept for years, diving into internet resources and pestering professors, yet I still find myself tangled in confusion. I'm reaching out in hopes that someone here can shed light on a question that has been haunting my thoughts regarding the nature...
In short, I'm interested in working on a web-app to make landmark papers in theoretical physics and mathematics more broadly accessible, especially to undergraduate and graduate students who are looking to catch up to modern topics (without sacrificing rigor or exactness of understanding), and...
Other than well known institutions such as University of Cambridge and Oxford. What are grad programs that are worth considering for a Phd? I am still narrowing down my niche, but I am interested in Theoretical physics, Mathematical Physics, and high energy physics.
As you may have noticed, I am obsessed with understanding the difference between two views of quantum mechanics, one of which can be called the "standard" view, and the other the "realist" view. The difference, of course, is very complicated, but I believe that the essence and origin of the...
Hi,
I am 25 years old living in EU. I am posting my experience with the objective of getting advice or opinions.
I have a bachelor in physics with a thesis on the SM electroweak sector.
I have a master again in theoretical physics with a specialization on Hadron Physics ( QFT ).
Both of my...
TL;DR Summary: I dont enjoy my lab subject.
I am currently in grad school (not US) and in the theoretical Cosmology laboratory, however I feel like I ended up in the wrong side.
I did undergrad research project in astrophysical data simulation and thought that this is what I want to do in...
I'm curious to get people's opinions about whether this is interesting enough to write up for submission.
I arrived at a set of coordinate transformations that are different from the Lorentz transformations, but which produce a coherent mechanical framework. It gives a very beautiful physical...
I am not sure if this is the right place to post this, so if not sorry in advance.
I am a second-year physics major, thinking of switching to mathematics. I have always been interested in both, but I could never be sure whether I could become a mathematician. Understanding physics was...
Hello.
I have been a member on this forum for quite some time and I came here because I've always had an interest in science, particularly physics. When I was in Junior High, I did very well in my science class but by the time I got to college, I wanted to make money. However, I realized that...
I am going into my senior year of hs next year and I am meditating on what I should major in. I have a keen interest in physics but also a love of math. The field in physics I would like to major in is theoretical physics/astrophysics, and the pure maths I am interested in are diff, algebraic...
I'm a graduate theoretical physics student at the (almost) end of his master's degree with a fairly varied curriculum, as I attended both QFT (and sub-courses on qed qcd etc) and GR courses. However in my latest intro to quantum gravity classes I familiarised with tetrads and, after a lot of...
I'm going into my final year of undergraduate theoretical physics. I have had a bit of a deviation in what I want to do and would really like to work in software development in the future. How difficult would it be for me to deviate from my current position and what steps should I take to to...
I want to do a masters related to quantum computing from a physics background and my criteria for the place is:
1. A quantum computing group with experimental realizations and
industrial ties.
2. A strong theoretical physics department with research in fundamental physics
3. A good chance of...
I was wondering if there is any such textbook which shows how a real physicist actually goes about developing models and or theories to explain experimental observations. I want to see how it is done in practice. Is there such a book? At a level that an undergraduate can understand. It is great...
I am have some questions that have arisen while reading an old but interesting article by Andreas Albrecht [1] that cites an article by Andrei Linde in the 90s on cosmic inflation [2]...Albrecht's paper is related to his ideas on "clock ambiguity" in which he proposes that the laws of physics...
I finished my 1st-year physics, took analysis, linear algebra, mathematical logic, classical mechanics, quantum mechanics(I was exempted from intro phy and took some 3rd-year physics courses)
I internal transferred to pure maths. The reason is that the curriculum of the physics programme in our...
By PDE. The book written by Walter Alexander Strauss perfect described a typical undergraduate PDE course I have in my mind.
It should at least include:
Laplace equations, waves and diffusions
reflection, boundary problems, Fourier series
The content of the book I mentioned can also be found...
Suppose there is a nonprofit that wants to order a piece of research in theoretical physics. The research is rather small; it consists in considering an issue and writing a 8-10 pages article. The physicist to do the research will be from a high income country; he/she should be an experienced...
I am about to start a physics with theoretical physics major, I've taken calculus before but I've not been satisfied with the "memorization of formulas" type books.
I started to read Spivak and found it enjoyable, but since it's a major undertaking I am also concerned for the practical value...
I stumbled across this series of 28 lectures by Dr Frederic Schuller of the university of Twente whilst searching for lectures about Lie theory. Having watched through lectures 13 to 18, I think they are simply superb (of course I'm assuming the rest are of similar quality). I only wish he would...
An interesting article about theoretical physicist Chris Isham (by Michael Duff) has been posted on the arXiv,
https://arxiv.org/abs/2112.13722
Combine this with (from "Group Theory for the Standard Model of Particle Physics and Beyond" by Ken Barnes)
Isham has written two books that I quite...
Hamiltons Principle and the physcial entity action are the terms in which modern physics is formulated. How do you know that you can always find a Lagrangian for a System which is then used for Hamitlons Principle and the formulation of Action? Why is the action stationary?
Hi, I am new here.
My main interest is in theoretical physics, mainly quantum mechanics; in particular quantum foundations and the quantum measurement problem, also general relativity and cosmology; in fact all aspects of theoretical physics.

Hi, I have the following problem, maybe someone relates.
I am about to finish my Bachelors Degree in Physics and must say it was a very unenjoyable road. I started it because since forever I was fascinated by the "great" ideas trying to explain reality that lie behind physics, i. e. Quantum...

I recently watched a video of Jeff Bezos explaining his journey from Princeton to Amazon. (watch from 24:39)
He said when it comes to theoretical physics, if you are not in the top 50, you are probably just wasting time. How accurate is this opinion ? Are most theoretical physicists just...
Hi, I'm interested in doing research in theoretical cosmology (the kind or work hawking did). Should I do an undergraduate degree in mathematics or physics? I'm in the UK so I can't do a double major. I'm well aware of the fact that interests change a LOT later on, but ideally which one is...
I recently came across a book called advanced theoretical physics -nick lucid. chap6 covers tensors and chap 7&8 cover SR&GR. I have studied a bit of SR before but never GR. At this point in life I don't want to read huge books on the subject. this book covers relativity entirely in three...
Hi all, my question is as title. I am a fourth year PhD student in US and planning to graduate early to get in industry or community college.
I major in high energy theory, and I have no coding/simulation skills at all (not interested at all). Thus, my situation is that professionally I have...
According to Michio Kaku, Nobel laureates have taken both sides towards string theory since some of them accept it and some of them reject it, as he says here (https://www.snowboundbooks.com/book/9780385542746):
“Kaku also explains the intense controversy swirling around this theory, with...
Hello,
I have several questions around the application process as well as the organization.
1. Are you aware of any reference website centralizing PhD offers by countries?
2.When it comes to the organization/management/ supervision of a PhD program, I wonder if there are differences by...
A year ago, I asked a question about two journals, both of which were predatory ( https://www.physicsforums.com/threads/are-open-access-journals-legit-for-my-cv.990744/ ). Thanks to the overwhelming advice I have received, I did NOT publish in either of those journals.
Right now I am asking a...
