Hi Does anybody know any free peer review services for research papers? Does physical review letters have a free peer review service? Thanks

Hi I would like publish my paper on Physical Review Letters. Publishing is free of cost on PRL as long as I don't want it open access & give them an electronic copy (such as pdfTex, Word), right? Is this the same for most journals? Thanks

Hi, Everyone: I am trying to help someone with their prelims, but ended up needing some help myself: 1)Show that every map f: CP^2--->S^1 x S^1 x S^1 is nullhomotopic 2)Is the wedge RP^2 \/RP^2 a retract of RP^2 x RP^2 ? For 1), I think we need to use the cell...

Hi, It's been a few years since my physics classes, and I want to do a quick double check to make sure I correctly remember the fundamentals of mechanical work. 1) At the most basic level, work is a force applied to an object, across a distance (that is, work cannot be calculated where...

I'm going into my 3rd year as a pure math major at UWO. I have completed both second year Real Analysis and Linear Algebra with decent marks. However, I really feel that I didn't take too much from both other than the general concepts, especially second semester of Linear Algebra (due to...

Homework Statement I'm actually only concerned here with proving equality. I would like some review of my proof before I crawl back to my professor again with what I think is a valid proof. The Attempt at a Solution Show: \frac{x_1+x_2+...+x_n}{n}=\sqrt[n]{x_1x_2\cdots x_n} \Leftrightarrow...

I'm beginning a directed study in QFT this fall and my supervising instructor told me I'd need to know some basics of Lagrangian and Hamiltonian Mechanics before we began (he also told me I needed to go back and review Perturbation Theory) since I'd need to know the formalism I guess? I've...

What should a literature review of a teeter-totter contain?

History Channel, great review "Joking!" This article at cracked dot com is really spot on and funny to boot. I did find one bad word on the page, so don't read that word. The entire article is worth reading. I especially love their table at the beginning. It made me *snork*. :-p...

There are several online materials on general relativity. Here I would like to get suggestions about concise review of general relativity at somewhat advanced level. The idea is that this should be enough for recapitulating the area at advanced level by somebody who had studied it thoroughly...

I was wondering what you guys think is most beneficial to do a few days before a test. Do you think it would be good to look over my notes/problems that I have already completed or to keep doing as many new problems as I can? Hopefully that makes sense, thank you.

actually i want two write a review article on issues related to civil engineering such as earthquake resistance,concrete(semi transparency) etc and i want to get it published. i have thought about a number of topics which were not so interesting .please suggest me with some good interesting...

It's difficult, especially for an outsider, to keep track of the multifaceted development of modern physics -- to even maintain a broad overview of research fields and directions, much less keep on top of the details. Review papers, I think, provide a good starting point to familiarize oneself...

I'm currently in an electricity and magnetism physics course and we're using the 8th edition of Serway. I'm looking for a review type book that focuses on problem solving with examples and explanations rather than theory. Here are the topics we are covering throughout the course: 23...

Please help -- review questions Hi there. I have an exam TOMORROW. I have prepared a lot but I just really need to understand the following in order to do the best I can: b) Calculate the average braking force acting on a car of 800 kg to bring it to rest if it was traveling at 20 m/s – I...

The result was surprising. Their "explanation" was nonsense. What is the reason that the boat is able to move forward? To those who haven't seen it, they put a fan and a sail on a model cart or boat, and as expected, it didn't move. They made the sail very small and it moved backwards...

Homework Statement I'm doing a review for a Mechanics exam I have tomorrow and this first problem given on the review struck me as odd. Problem Statement: An 89kg boat that is 6.6m in length is initially 7.1 m from the pier. A 27 kg child stands at the end of the boat closest to the pier...

This doesn't seem to be a typical type of question for this site, but I need help choosing a topic for a literature review in an advanced writing class. It needs to be related to computer or electrical engineering, and is described as follows: "A literature review is a very common genre of...

So long story short, I have a friend who wants me to help her learn how to factor cubic polynomials. Normally I would just fess up and say I don't remember but it's something I'd like to review myself and lessons online aren't the clearest. Here's one of the questions: 2x3+3x2-8x+3 I...

I'm in a second year Calculus class, and we're doing review from first year integration, and it's just unbelievable how easily this stuff leaves your memory. I shouldn't have thrown out last year's notes. I can't for the life of me remember what techniques I'm suppose to use to integrate...

This is my first post, so I hope am writing it in the correct sub-forum. Hello guys, I am a post-bachelor, pre-med student that will be starting the general physics requirements in the fall (2011). Medical schools only require algebra based physics, and the vast majority have dropped...

I'm taking Modern Physics in the Spring semester (starts Jan 10). It's been over 5 years since I took Mechanics and EM. Which topics from these courses should I review in preparation for Modern Physics? I plan to review everything, however this will take me longer than the time available...

I have to finish my investigation and the outline has something called a Theory review. It defines it as: a story that generates interest in the reader for the field of your research and link to practical investigation to follow.:confused: Now this maybe very simple but I'm not sure what kind...

[PLAIN]http://img820.imageshack.us/img820/7729/3iiin.jpg So I gave it a go, and I just want to make sure my argument is convincing: If f is uniformly continuous and unbounded on [0,∞), then for some c in [0,∞], lim x->cf(x) = ±∞(notice the closed brackets, I wanted to leave the option that c...

Hey everyone! Need some help on this Financial aid appeal letter to the committee at my community college. I was going to post this to academic guidance thread, but physics is not involved. I went over 150% of program hours and they will not pay for my class that is actually towards my A.A...

I thought maybe this should go in the Precalc Learning Materials section, but since I can't post there this seems like the next best fit. If I've picked the wrong forum, I apologize in advance. I need a quick review of everything leading up to Calculus. From basic algebra up, essentially...
