Physics Definition and 985 Threads

On 22nd February 2025, I was scrolling through countless of Instagram posts with no purpose in mind. That was until a post which gave me recommendation on educational websites on several subjects, including Physics, to learn at this website (Well, it's one of the recommendation, and I took an...

Hey everyone! I'm a 13 year old student who is potentially the worlds biggest physics nerd :D I don't have any actual qualifications, but I've thoroughly studied many textbooks such as University Physics (+modern physics) by young and freedman, as well as having read many many books and theses...

I have a Bachelor's degree in physics with a minor in mathematics as well as some formal education at the master's level. I have continued to educate myself after graduation by studying on my own. I am most interested in quantum field theory and general relativity. Someday I hope to deepen my...

This is another follow up in my campaign to have a separate forum for history of science. Similar to my on-going thread Interesting anecdotes in the history of physics? this one would be about specific quotes. What are some of the memorable quotes said by physicists? [I will allow...

I became interested in physics and was looking for a place where I could find information or ask knowledgeable people. I want to study physics as deeply as possible, according to my abilities, because during my school years I didn’t think that it would be so interesting to me and I went into a...

i recently bought books for (self study) Mathematical Methods of Physics, Thermal Physics, Classical Mechanics, and Introduction to Electrodynamics. I should probably get an upper division Modern Physics book before going to Quantum Mechanics (Griffiths). What is a good/usual Modern Physics...

through all my courses in my physics ( took 2 Mechanics & E&M ) i found the beauty of physics through gauss law this simple law that made me love physics solving gauss law problems graphing gauss law problems is simply fascinating also because someone said that physics is hard and i want to...

Hi, i'm a physics student in Colombia, and i will graduate the next year, ive been wandering if i should do an internship in a company with something related to data analytics or a research internship. The first option could help me get into the labor market, since is very hard to get an entry...

I'm newbie. I'm just a physics enjoyer. I have a questions to discuss.

I was just skimming some reading on Bohmian mechanics and for some reason decided to check on Basil Hiley. He was co-author and close friend of Bohm. I just noticed he died a couple of weeks ago. He was supposed to hosting some event on Bohm's next month. Quite champion of the field. Hopefully...

My name is Jeff. My interest is in the Cosmos. I received an AA in Physics (with Transfer) and then moved on to computer science. I spent 35 years in the computer science field. I've always been intrigued by the planets and the solar system. My interest was rekindled with the Carl Sagan's...

I am always thrilled about physics, and science in general. It shows me details of everything. I want to know how things work. I have been reading physics my materials for great knowledge. Then I also try to discover some.

I'm wanting to delve deeper into physics.

I use ChatGPT at this point as basically my personal tutor. It has been a huge help in learning Python code, fixing issues when I'd have them, verify it's working as intended, etc. Also helped me with some of my problems in other classes too (it's difficult for me to make it to office hours a...

I was searching self study group to learn physics and found this forum via Google search

Can someone prove kinetic energy is inversely proportional to potential energy?...I cant find any ans on internet , and I am unable to trove this.

I want to apply to Cambridge University for theoretical physics for undergraduate degree.I want to ask that should i chose natural science tripos or mathematical tripos for theoretical physics? I am also aware about the option(b) 'maths with physics' in mathematical tripos,but it is a one year...

could you build a container to isolate cosmic radiation so that you could get it down to 0 kelvin, halt the movement of atoms, and make everything still in this box, (to my understanding) therefore stopping time in this isolated box? I'm not a scientist, I just watched steins gate.

I'm a theoretical physics student working on my master's degree in China and trying to seize the opportunity to study abroad, especially in France. It's so frustrating that I still cannot find a subject or thesis that satisfies both my interests and learning goals. Here's the thing. I major in...

Pink Floyd might not have gotten their prism exactly right, but this is the official poster of the Swiss section of the Physics Olympiad :smile:

Hi! My name is Liliya. I like physics, actually more than mathematics, but due to the fact that they are connected, I will have to learn mathematics.:( I hope I can find answers to my questions on this forum, but again, I started learning the basics of physics and mathematics, and all such...

Hey all! I'm a physics undergrad student right now, hoping to go to grad school, then into plasma or particle physics research afterwards. I do a lot of hobby science. I built a fusor a few years ago, but have not claimed fusion. I am hoping to gather enough evidence to do so once I get out of...

We often hear knowledge is power. That's true but studying Physics told me that Knowledge can be entertainment as well. When I started learning Physics instead of just studying it, I found how beautiful and exciting it could be exploring this fascinating universe. Being a Physics graduate and...

Hello...in my 50's and been in the electrical field since 95. As an adult have always been fascinated with physics. I regret not being more astute as a student.

Hi! Looking forward to learn.

If so what does the reflection look like?

I am doing some experiments related to the physics of the singing voice. I am wondering if (once I reach an appropriate stage), the methods, results and tentative conclusions can be an appropriate subject for an Insights blog. I am asking because the guidelines do say that "personal theories"...

Me: Curious citizen. No formal education in physics. Enjoyed prof. Susskind youtube videos.

Hello all, glad to be here I'm passionate of physics, especially quantum physics since my youth decades ago, and have come to the point to be able to introduce myself as a living example that one can come to a basic understanding of quantum physics with very little mathematics. It's possible...

Hey all! My life has been interesting. Long story short, I sold my company last year, have a lot of time on my hands, never have to work again, and want to just learn physics for no reason other than it’s awesome. I’m currently totally off the grid in a jungle in Hawaii and am splitting my time...

Hey all. I am creating an MCNP input deck but my geometry is appearing red in the vised plot and I am receiving errors relating to the geometry and material card sections. Could anyone potentially help me figure this issue out?

When I realized the list of existentially depressive things I accidently came to Theoretical Physics (from Law and Economics) and now I'm looking for some kind of tutor.

I’m here to connect with others who appreciate the beauty of math and physics and to find support in spreading this knowledge to more people. Looking forward to learning, sharing, and growing with this community!

Want to go deeper in discussions on some relevant topics

Im a younger student who has a profound appreciation for particle, theoretical, and nuclear physics.

I apologize if this has been asked before. I searched on this site and others but didn't find this particular issue. My background is physics and math. My question is near the end of the post. First, let me explain my thoughts leading up to my question. After many years, I'm reviewing the...

Hi everyone, I’m a first-year physics student currently taking my end-of-semester exams, and I’ve been feeling really discouraged. Physics isn’t what I thought it would be, and I’m struggling to stay motivated. My courses include Calculus, Linear Algebra, General Physics, Programming, and...

I've been working on a problem for a while now, it's taken me into various directions, but I think I finally figured out the puzzle. But unfortunately I can't take it really any further, cost effectively, without some computer simulations of the experiment. It's all basically physics based. I...

I'm just here to learn and contribute my understanding of quantum physics and mechanics to science and engineering for the world. I don't claim to be the best, I only claim to be able to contribute what I understand

Physics Today has collected a bunch of quantum articles from its pages here. https://pubs.aip.org/collection/584553/Quantum-archive

I'm bored out of my mind and while watching a PBS spacetime video I had an idea. What if black holes are hosts to universes in between the singularity and the event horizon ? It's 3am so pardon my lack of precision, but chatGPT did formulate my idea pretty well in this conversation : Link to...

A problem about hitting a mass up into the air has disappeared from the intro physics homework. It was a bit of a train wreck, but the OP was replying and perhaps was willing to work on it. Happy New Year.

Hello, I'm a college physics student, stumbled upon this forum when I was looking for an answer to an assignment, it's nice to meet you all

Eight possibilities. Elsewhere she says that Marie Curie's thesis is literally radioactive. I'd vote for Bernhard Riemann's 1854 thesis which introduced the manifold concept. It was math but is the foundation of many modern theories in physics so I say it's close enough.
