Hello, everyone! I've lurked around for **years** before even making an account! Being a sophomore, studying physics and astronomy, I'm still so new. I'm so excited for the semester to start. Thanks for all of the wisdom. Miss Carraway

Hi everyone. I'm a sophomore now , majoring in astronomy, and will become junior in no more than 1 month. I have a good command of classical electrodynamics and quantum mechanics. However, I'm confronted with some problems. 1. I want to know more about Astronomy. I borrow Very High Energy...

I am looking for a short pedagogical introduction to Young-tableaux and weight diagrams and the relationship between them, which contains many detailled and worked out examples of how these methods are applied in physics, such as in the context of the standard model and beyond for example. I am...

Hi, I'm Jerry, a 74 year old retired engineer. Although my degree is in electrical engineering my approach to problems has generally been from the applied physics standpoint. I have recently become interested in space flight methods. Lots of Newtonian physics there! I ran across this forum when...

Does anyone know of any gentle, introductory books to LA that assume little prerequisites, even in the way of vectors and matrices? I want something that will give intuition and reasonable proofs, and will provide enough background for something like computational neuroscience. I do not know...

I want to read some books on the major different fields(solid state,computational and any other except from medical physics and the astro,theoretical,cosmo stuff) in order to get a feel for what I might want to pursue later on my degree.I don't want it to be a textbook as you might agree...

Hello, I am major in physics in the university. Physics is the thing which fascinates me a lot. After I touched the beauty of general relativity, I found that I cannot have a day without physics. However, physics is such a difficult and confusing subject that I often meet some obstacles and have...

It's awful, the reading of this first chapter is extremely boring, he appears only to cover divergence and convergence of series, should i skip this chapter?

I'm about to enter college as an Electrical Engineering student, but I am considering changing my major to physics. Before I commit, however, I would like to take an advanced physics course (QM, Classical Mechanics II, Thermodynamics, etc.) so that I can get a feel for the mathematical rigor of...

I'm aware that most modern textbooks gloss over relativistic qm and jump to qft. Since I'm not that brilliant of a student I'm thinking that i should firstly familiarize myself with relativistic and then go to qft. So my first question: Is it worth it to study relativistic qm or should i jump...

[Mentor's Note: Thread moved from the New Member Introduction to General Physics] what are the physical interpertation of entropy?

Hello, Physics Forums. I'm a new member to these forums. When the school year starts again, I'm going to be a freshman in high school. I'm mostly an autodidact due to my dissatisfaction with my past school's learning pace, disinterest, and due to various funding costs for higher learning. My...

Hello, I am a Junior Math and Physics undergraduate and I just wanted to get involved in this community. Thanks, -E

Hi all, I have an undergraduate degree in Physics, but I've since specialized in more environmental applications of Physics. I've taken a few quantum Physics courses as part of my degree, but, if I'm being honest, what I took from those courses was more of a mathematical view of the field, such...

I came here after noticing a thread I found amusing where someone named "vanesch" said in this post that theories like SED are unneccessary ontological "toy worlds" for people who need to have an explanation behind the formalism of QM, to make themselves feel better. Mainly I just wanted to...

Can anyone recommend a good Introduction to Numbertheory with excercises and of course proofs Thanks for any recomendations.

Hi, this is Shrey and I am from India. I like classical mechanics, electrodynamics and a wannabe in quantum field theory. As for my username here, I made it for AOE, it's a German and Japanese combine, go figure ;-) Thats all about me.

I figured it was about time I made an account, since I've come across this forum regularly while searching for comprehensible examples of various topics in Physics. I study Applied Physics at TU Delft in the Netherlands and plan to finish my bachelor's in two years time. My main interests are in...
