Hello,I have been going through Griffiths’ Intro To Quantum Mechanics in an attempt to self-teach myself some quantum mechanics. I am currently in section 3.4 (Generalized Statistical Interpretation) I am seeing a “step” occur more than once. When I first came across it, while I didn’t...

I'm struggling with the math used in my college's calc-based honors physics class, even though I've taken calculus 1. ---What are some good books/resources to learn the math used in introductory physics?--- Preferably, it'd be nice if the math was taught using examples in physics. Having that...

I don't understand a good portion of the non-algebraic math behind much of the physics in my first semester college class. I understand everything with algebra, and can solve all problems, but I don't understand the relationships with vector cross/dot products, calculus derivations, DE, etc...

Hi guys. I am a math student trying to learn mathematical physics.

Basically, I'm a Physics/Math MSc student. Currently strengthening my background in Diff. Geo., QFT, GR. I feel like I should start reading some research papers on Quantum Gravity but I do not know where to start. What papers should I start with? I need papers that are accessible to 2nd year...

I’m 3 weeks into my first physics class at college; honors physics 1. I really want to major in physics because it’s really interesting, but I’m finding the class very difficult. Trying to solve the textbook problems and follow the professor’s train of thought is very tough, which is frankly...

Hello, Is there a difference from these courses, or are they the same course with different names? I need to know which one to choose for the upcoming semester... Intro to Analysis, Intro to Real Analysis I, and Numerical Analysis Thank you, Tracie

Does anyone know of a good resource for semiconductor physics? I can't find much for it and the textbook isn't much help. Here is a https://filebin.net/8navybb1hnt50wi9/Formulae_2017.pdfandhttps://filebin.net/8navybb1hnt50wi9/Formulae_2017.pdfthe textbook is an introduction to semiconductor...

I am not sure what, why and how I should do this introduction, so i will just do it like a regular introduction. My name is Mark, I and a second year chemical engineering student. I often run into question which I have no idea how to answer, or where to find information. So I figured maybe it...

Many have recommended me Resnick for intro physics book, however I already have Kleppner for mechanics, so should I continue just getting a book for thermodynamics and then for EM when I need them or should I get sth like Halliday Resnick? I have noticed, that separate books per subject tend to...

Homework Statement ca(0)=1, cb(0)=0 zeroth: ca(t)=1, cb(t)=0 1st: ca(t)=1, cb(t)=i/hbar*integral(H'(t) exp(iwt)) dt ca^2+cb^2=1 to 1st order of H'.: What does it mean? it is evidently not 1 at all. Homework EquationsThe Attempt at a Solution

Homework Statement If event A equals event B, then the probability of their intersection is 1. True or False? Apparently the correct answer is False. The Attempt at a Solution If A=B then they should overlap entirely and their intersection should be 1? The only way I see this working is if...

Hello all, I am a undergrad student studying physics. I like how physics tries to break down every phenomena into a set of laws/rules that can be used to derive anything. Like most physicists, I have a dream to come up with a set of the most fundamental rules/laws using which the entire...

Hi guys, could you please recommend a valuable introduction to climatology and/or atmospheric physics? It could be a textbook, online book, article, tutorial, etc... Thanks in advance!

Connections between algebraic structures and geometries are mentioned in almost any course of modern geometry or algebra. There are monographs dedicated to the subject. Unfortunately, the books, I managed to find, are written for professional mathematicians. I am looking for a book that focuses...

My ultimate goal is to become a theoretical physicist, a great one at that. I have mastered the prerequisites and I am now looking for rigorous calculus textbooks that make some references to physics, or are more orientated for people who want to become physicist.Thanks for your help.

Very brief and no math, the author is more about the veracity of checking original sources over retelling pop sci stories. All has been said here previously but scattered over many threads and easy to miss for newbs. Might be helpful to beginners who's only exposure is sensational pop sci...

I am self studying the Book- Introduction to Quantum Mechanics , 2e. Griffith. Page 47. While the book has given a proof for eq. 2.64 but its not very ellaborate Integral(infinity,-infinity) [f*(a±g(x)).dx] = Integral(infinity,-infinity) [(a±f)* g(x).dx] . It would be great help if somebody...
