Since my other post was ignored, I'm reposting a greatly summarized, simplified version. Can someone teach me the basics of working with significant numbers? Here's the 2 example problems I'm working on. Display the answer to the correct number of significant digits. 1. 142.47 + 30.2...

Introductory Physics Formulary This sticky is meant to be a repository for some basic equations commonly used in elementary physics that might prove handy to homework posters and homework helpers. The equations will be in Latex format so you can quickly copy them. (For more about Latex, go...

Hey, university started and in less than a week, we allready have to hand in an assignemnt. I did most questions, i was just wondering if somebody can help check some of work - its more english than math :mad: Q1) True or False - A statement and its negation may both be false. A1) False -...

Hi, can someone help me with the following question? Q. A particle is suspended between two cylinders each of radius p (rho) by means of a massless rope of length l. It's instantaneous position can be determined by the angular displacement a (alpha). Motion of the particle is restricted to...

I'm not talking about Elegant Universe level, but something that would give a nice introduction into string theory and its theories (with math, of course) for beginners would be nice. Any ideas?

Someboy can give me an introductory explanation about dualities? I mean, what are, how works in theory and what physical sense do have it? I have to start some study about using dualities in linearized gravity, so i'll be very helped if you have too some basic literature at respect. Specifically...

Hi. Can anybody help me with this exercise in Introductory Nuclear Physics: One of the magic numbers for nuclei is 28. How many stable isotopes exist with N = 28. (N being the number of neutrons) I have no idea on how to solve this. Thanks.

This thread is here to organize the many tutorials we have for Introductory Physics, which we take to be any and all General Physics courses that are either algebra based or calculus based. This thread will grow as the number of tutorials grows.

Where to take "Introductory Modern Physics" online? I missed taking "introductory modern physics" this semester and need it for my junior classes. Does anyone know of an institution that has an online class for it? Or I would even study it independently and take a test on it. Help!

Hello, I was wondering if any of you can suggest some good introductory textbooks on GR around the graduate level. Thank you for your time. Yours Truly, TK.

I'm looking for a nice easy to read introductory book in physics (classical physics ?) for someone who has two years of university level math but knows nothing of physics. To be more precise, I want a book (preferebly cheap), that won't take too much effort to read and gives me enough...

Hi, I'm a high school senior in my first semester of Calculus, so my math is pretty limited at the moment. I was wondering if you guys could recommend any introductory number theory books that you think are about at my level. Any suggestions would be really appreciated. Also, sorry if I...

I need a recommendation for the best introductory real analysis book to use for self-study. I haven't really had much experience with rigorous proofs and also need a good introduction to that. This coming year I will be using Rudin's Principles of Mathematical Analysis, so any book that would...

Hello everyone, I'm a bit of beginner to the more complicated algebra and geometry. I am going into grade 12 next september, but I'd like to get a headstart on the material, and I am wondering what introductory "advanced" (for say) Algebra books were of benifet to you. A first year university...

I am currently beginning to conduct something like an introductory, very elementary, seminar on string theory at my local institution. The plan is to perform the whole thing in parallel on the web. The lecture notes are being published bit by bit at the String Coffee Table, namely in the...

I am a first year university student (and have taken chemistry and physics through high school, and still do) and was wondering if anyone had suggestions for reading that would give me a good introduction to the basic background ideas behind quantum physics. I've already learned a good deal...
