I found this website to share all of my self-study notes from the past year in the form of a big book! None of the work is AI-generated, and mostly comes from YouTube, Wikipedia, college PDFs and other physics/math websites online like Wolfram MathWorld or or Physics LibreTexts. Now that I am...

Hi newbi appreciator. I posted my unification theory before introducing my self. I am a retired software developer with a passion for problem solving. Look for my TBCT unification model and let me know your reaction.

My name is Marc Patch. I am a composer of classical contemporary music. However I have had my best friend whom I knew during 52 years who was a physicist and he died on the October 24 2024. He was working on a discovery and was almost done but he died before. I need your help to validate his...

Hello everyone! I’m a student with a deep interest in physics, and recently I developed a conceptual hypothesis that I haven’t seen addressed directly in scientific literature. It's something that ive personally searched at a lot of places for many years. Reddit, Stackexchange, YT videos but...

I found Physics Forums via a Google search. I was working on a particularly challenging physics homework problem related to electromagnetism. I typed in keywords like "physics problem solving forum" and Physics Forums popped up at the top of the search results. The description mentioned that it...

I am a retired engineer that still is interested in physics, mechanics, programming, designing, experimenting, prefering the cases where these disciplines are closely related. I worked my whole life at the same institute in the Netherlands, but over time in different functions. I started with...

TL;DR Summary: Solved the biceps, but having trouble finding the reaction force now. I eventually calculated, using the moment, that the force exerted by the biceps is 1536 N (this is correct according to the model solution), but the calculation of the reaction force is more difficult. I was...

Hi everyone, I'm excited to join this physics forum and appreciate the open platform provided by the site owners, especially for discussions around the emergence of quantum physics theories. While I don't have formal credentials in physics, I'm deeply interested in the subject and have pursued...

I have a bachelor's degree in physics (medical physics specialization) and want to go to medical school. However, the medical schools in my country do not accept students who have already earned a bachelor's degree and are over 22 years old. Medical schools abroad are competitive and, most...

I'm looking for some method to focus a variety of sound frequencies in the environment via metamaterials, parabolic reflectors, Helmholtz resonators, or some sort of device that can somewhat "attract" sound from it's regular path. I've heard about Schumann resonance in the atmosphere and I was...

Nothing exceptionally new here, but I want to shift gears in my teaching practice and increase the Inquiry Based Approach more and more. Have you ever taught with this approach, what resources did you use, and what results you had ? Thank you for your cooperation

How does Engineering Mechanics books differ from physics majors' Mechanics books? Are there any topics which aren't covered in the physics curriculum? I plan on reading this summer some Engineering Mechanics book (Hiebler looks like sort of canonical for UG stuff). The best learning is by...

Keen to “re-learn” physicis

I am Anirudh from India. I am young but very passion about classical and quantum physics. I have so many ideas in my mind but can't find anyone to show me the way forward. I wish that by joining this forum I can development myself as one of the best physicists ever.

Hi I am a currently a 24 years old middle school teacher looking for a career shift. I want to talk about few things in this thread First, what skills i can learn in a busy schedule? Alongside my job, I spend a lot of time on my graduate diploma, and i have to take some of my work home, I find...

Where is best place to buy math/physics books, textbooks online? What site has best combine shipping option? Problem is shipping is often higher than book, when you buy a few books, shipping kill you. Especially if you are from EU and buy from US, Asia

I’m reading Lee Smolin’s 2006 book ‘The Trouble with Physics’ and wanted to check on the empirical results on double special relativity from tests in progress, Auger and GLAST IIRC. Curiously the two individuals in a quality deep dialogue talked about this very book and the exact section I was...

Hello, my goal is eventually to go to grad school for physics. I am not yet sure what sub-field I find most interesting because all of them are very interesting to me. Of Rensselaer Polytechnic Institute, Stony Brook University, and University of Rochester, what college will provide me with...

Hello, everyone! I find Physics Forums a heaven for me as I can always find what I want here. And decisions to join this group are made a long time after I first encountered the forum. I like math and physics though not talented and suffer a lot from them and nothing more comes to me. However...

Hello world. It's amazing to me find a community where to share ideas about physics, I feel that is important to discuss about whatever you want to learn, because enrich the ideas that you have, and correct whatever ones that are wrong. I expect to share a lot with you all and learn. Thanks...

Hello! So I'm a teenage physics enthusiast, who wants to take my knowledge past A-level (or in America I believe this would be high school level) physics. I've studied multiple textbooks like Young and Freedman's University physics, studied maths from books like mathematical methods for physics...

Spacetime is the foundation of General Relativity, describing how mass and energy influence the curvature of space and the flow of time. However, an important question arises: Is spacetime a physical entity, or is it merely a mathematical framework? Physics relies on measurable quantities and...

Hello everyone! My name is Thi, but you can call me Uncle Thi. I’m from Vietnam and joined this forum because I have a strong passion for physics, especially in understanding the nature of reality, space, time, and quantum gravity. Although I am not a professional physicist, I spend a lot of...

So, I was just doing some practice on Gauss's law, and most of the questions, when I needed to take the surface integral of something, it would be something simple, like a sphere, cylinder or at worst a torus. Though it's impractical (and probably useless) - it got me wondering, what would...
