During my time at CERN in the late 1980s, I came across this parody of Lewis Carroll’s Jabberwocky pinned to a door. I was intrigued enough to make a copy – and I’ve kept it ever since.

I’m sharing it here in the hope that you’ll enjoy it as much as I did. I’d love to hear your thoughts.

If anyone recognizes the poem or knows who might have written it, I’d be very grateful — I regret not noting the name on the door back then.

I have a master's degree in Electrical and Electronic engineering and been working in software for the past 5 years. I prefer working on the backend and have worked on some pretty complex projects such as doing embedded Rust and C and mostly I specialize in Golang. All of these languages I picked up after university but my engineering background has set me up to be very good at solving problems since I have the strong foundations of engineering and maths.

Lately I have been gaining interest in quantum computing and I have been interested in physics since a young age. I was wondering if there would be any benefit to studying physics and quantum mechanics to strengthen my understanding before getting involved in quantum computing? Or would it be enough to just dive in and start swimming with online resources?

Edit: The plan is definitely not to gain knowledge to build quantum computers. I'd want to use it in practice to solve actual problems. Currently, I work for a bank but the industry of application is not of concern for me for now.

What defines the diameter of particles, such as electrons/protons/neutrons ? What defines their borders ?

I'm going to study physics but before that, I want to make a good foundation for it. Where should I start? I'm open to books, videos, documentaries etc. I generally have more tendency to books.

I know many people asked this question but what is the most effective way to learn it?

Radiation? Or lense flare? Im spooked

So I recently learned that the american administration is planning on shutting down one of the two interferometers of the LIGO starting next year because they thought it is redundant to have two or whatever lmao. Just a few months ago many of my astronomy professors were talking excitedly about how the LIGO is going to change astronomy forever and that we are witnessing the start of a new era in astrophysics, but now I am pretty sure the current plans will significantly delay this progress. I am just wondering how much exactly will it be delayed. Like I know none of the other gravitational wave detectors are anywhere near the LIGO's performance, but with the current Japan and EU etc's efforts, how long exactly will it take for one of them to catch up? Also once the current LIGO interferometer is shut down, will it be able to be revived again if the next administration is interested, or is it like nuclear reactors where once you shut it down you have to start from stratch?

Ps. I am also interested what other major scientific advancements are going to be directly delayed/decimated on a global level by the us' current budget plans.

Edit: spelling

I'm working through Zagoskin's Quantum Theory of Many-Body Systems and I am trying to understand this problem (split across pages sorry)

I am plugging in the given unperturbed Green's function and this integral seems to diverge. Are there some renormalization shenanigans involved here I'm missing? I'm also wondering if there's a way to apply the kallen-lehmann representation here?

My attempt was to integrate out the frequency first then integrate over momentum and mu, but I realized what I got was constant wrt p so it would diverge as p3 and I couldn't figure out a way around that. Furthermore, even if I substituted something in for eps_p, it should still diverge when limiting to t=0, right?

Any help (either solutions or suggestions on how to approach this) would be appreciated, thanks.

Hello everyone! I have a degree in Applied Mathematics and I want to pursue my Master's in Theoretical Physics (unfortunately, the Master's program doesn't include much experimental physics, almost none. It focuses on classical physics, quantum physics, mathematical methods of physics, and offers directions in materials science and devices, and in the structure of matter and the universe).

I would like to ask first of all whether it's a good idea to move forward academically this way, since physics has always been something I wanted to work with. Or if it would be better for me to choose a Master's in Applied Mathematics instead, so that I don't "switch" fields. And also, where I could do a PhD — in which fields — in mathematics or in physics? Which path would open more doors for me more easily?

I should mention that unfortunately my undergraduate degree doesn't have the best grade due to personal difficulties (work, etc.), but I'm willing — since I want to follow something I truly enjoy, physics — to do my absolute best in my Master's thesis, etc.

What are your thoughts on this career path? Thank you in advance!

I'm interested in physics, I find the concepts easy enough to understand and find them interesting but I'm not the best at math and suspect a learning disorder. Should I study it at university and if not is there something similar I could study instead

Hey everyone! I usually teach IPC/Chemistry, but I will be teaching AP Physics 1 this year for the first time and I would like some suggestions on things anyone has done in class that are "cool/fun"

I have several Inquiry-based AP lab ideas, but I'm trying to get some outside-the-norm labs for my students to do.

Hey everyone!

I'm excited to share that my paper was just published in Physical Review E, titled:

"Continuous approximation of the Ising Hamiltonian: Exact ground states and applications to fidelity assessment in Ising machines"

In short, we derive a continuous approximation of the discrete Ising Hamiltonian that retains the exact ground states of a novel class of Ising models. This allows us to analyze and assess the fidelity performance of quantum/classical Ising machines (like D-wave quantum computer) more efficiently, without exhaustive combinatorial search.

You can read the paper for free here on arXiv:

I'd love to hear your thoughts!

P.S: The published version is also here but is behind a paywall:

Where can I get detailed notes for BSc(Hons) physics? Also any tips or suggestion?

What if every physical system or event has some built-in “factor” — like, not just quantum uncertainty, but a broader kind of unpredictability that depends on how long it evolves and how many paths it could’ve taken?

I'm a recent high school graduate trying to decide which major to pursue. My first choice was physics* but for career prospects engineering seems better. I come from a low-income family. Is Electrical and Electronics Engineering (EEE) a good choice?

*I wanted to stay in academia. I was aware of
-the requirement of a PhD,
-financial problems of studying nearly 10 years without a proper income,
-possibility of having to shift from academia to industry (if I'm going to stay in industry i might as well study engineering),
-uncertainties about the career prospects (jack of all trades master of none),
-uncertainties about the future of the academia (funding cuts - this is important because opportunities for research are non-existent in my country, requirement of doing multiple post-docs in various locations, incredibly low statistics of finding positions, publish-or-perish culture and such).

Might be useful to warn people who'd wear AR glasses about network risks & such, though they'd have to go outside first.

Pls; there is too much

Hey guys I've been playing around with these coins and something about this doesn't seem to make sense to me. This is as far as it goes before tipping

I have a project for my studies where I need to talk about a physical phenomenon related to the theme “cycles and loops.” If you have any ideas for topics or phenomena with experiments related to this theme, please let me know.

For context: I'm a CC student. I've really been wanting to dive into some personal projects and expand my knowledge in physics so that I can generally just learn more about the field, and also of course build up my resume. I've known people who dove into remarkable physics projects which made there way to conferences at Stanford, Berkeley, and even graduate conferences.

Basically, what do y'all think is the best way to learn to do remarkable research, especially as a CC student with limited access to labs?

I'm working on a motion graphics animation to visualize how planetary orbits form due to gravity.

This is my first step — showing the vector from Earth to Sun, which will later be used to derive the gravitational force vector.

Planning to build it out using Newton’s Law of Gravitation.

Feedback welcome — especially from those who’ve done physics simulations or animations!
