Introduction Definition and 848 Threads

Hello there I have to write an interdisciplinary project at school, in mathematics and physics, where I have to go beyond what is covered in the syllabus for mathematics. I have chosen the subject of chaos theory. Can you recommend any good introductions, on this subject? And would I need...

I am just an undergraduate student of physics and I would like to know what would be the best (most pedagogical) introduction to Hawking Radiation.

Page 87 of "Introduction to Set Theory" Sorry, if this post doesn't fit into this forum, but i had no other choice. I got a electronic version of "Introduction to Set Theory" by "Karel Hrbacek" and "Thomas Jech". It is a magnificent book which opens up every window of understandings of...

Hi, I'm learning special relativity with the book Introduction to Special Relativity by R. Resnick, but unfortunately he doesn't provide answers to the questions (not problems). So I would like to aks you if you could correct some of my answers. Homework Statement 1. Can a particle move...

hello, in my calculus introduction book, it is written: Let a rational function: f(x) = \frac{{p(x)}}{{q(x)}} and a, a real number If q(a) equals 0, but not p(a), then {\lim }\limits_{x \to a} f(x) does not exist. however, while doing exercises on the internet, i found that: {\lim...

Hey guys here, I am going to university soon. Introduction to Multivariable is one of the courses. Before going to university, I hope to do some self-study as I am relatively weak in math. Hope that with an extra prepared Math module I can cope well during my university's life. May you...

Hello. Right now: we're learning about derivatives. And the questions reads: Determine the coordinates of two points of tangency to the curve y=-2x^2, given that the corresponding tangent lines intersect at (2,8). What I know: I know that the derivative of the function is y'= -4x I know...

Hello, I have read in a susy introduction paper that if we call Q the charge which links fermions and bosons, then we have the following anticommutation relation : {Q_a, Q_b} = 2 sigma_ab P where P is 4-momentum. So, is this relation only due to Coleman-Mandula theorem which force the...

Look am very interested by computer programming and now am learning The C++ language that's why i would like to ask anybody who can teach me java, just thank you

Hi, hope this is the right area for this. I'm currently doing preliminary research for my computer science dissertation. I'm thinking of doing something in CFD...either representing the effects of wind on fur, or simulating a river flowing. Most CFD 'googles' have resulted in me finding...

If you want an accessible overview of quantum cosmology try this TOC: https://www.physicsforums.com/blogs/hellfire-3727/category/interesting.html Hellfire covers different attempts made since the 1960s, and by comparing them (and showing historical development) makes the whole subject...

Hi everybody, I'm a freshman and i want to study signals and systems. so I'm seeking for a good introductory book. I've heard about the book "Signals and Systems" written by Oppenheim and Wilsky. So is Oppenheim's book suitable for a beginner? If you know a better introductory book...

Homework Statement you are in a land inhabinated by people who either always tell the truth or always tell falsehoods. You come to a fork in the road and you need to know which fork leads to the capital. There is a local resident there, but he has time only to reply to one yes-or-no...

we have two inertial frames, S and S' where S' is moving with speed v along the x axis. here are a few questions about these frames: 1. if two events occur at the same point in some inertial frame S, prove that their temporal order is the same in all inertial frames, and that the least time...

I just read a news on physicsweb: http://physicsweb.org/articles/news/11/3/9" This is called a "quantum non-demolition (QND) measurement on single photons". I would like to know a little bit more about QNDs. Why they are called so. What is special about these QND experiments, or maybe...

Are there any good online introductions to topology?

Note: This article will assume the reader is familiar with the concepts of statics and soil mechanics (mainly the topics of shear strength in soils and effective pressure). 1.1 Introduction Retaining Walls A wall designed with the purpose of keeping a level difference of the soil on its...

I have several books on linear algebra but they all bore me to death. What I find annoying is that they all focus on giving tons of definitions on the opening chapters only to elaborate on the relevance of those definitions later. What I am looking for is the opposite; a text that gives the...

what do you think about the book: Exploring Black Holes: Introduction to General Relativity by Wheeler? Do you think i should buy it? Thanks.

If we have Einstein-Hilbert Lagrangian so: \mathcal L = (-g)^{1/2}R for R Ricci scalar (¿?) then my question perhaps mentioned before is if we can split the metric into: g_{ab}= Ndt^{2}+g_{ij} dx^{i} dx^{j} N=N(t) 'lapse function' then i would like to know if somehow you can split...

I am just starting in elementry Physics and so in fear of asking an over simplified Question Can some one break down the common Law's of Physic's relating to natural occurances such as Motion/Electricity/Vortex's and any other relitive information you may deem esential. Mark

It is assumed that the reader is familiar with the basic concepts of structural analysis. Further on, I am aware of the possible inconsistencies and errors in this writing, and hereby invite all who have comments and objections to contribute and help to make this small tutorial useful for...

I'm searching for a book that will introduce me to Calculus with practice problems that have some application to Physics (I would prefer this). I think I may have found a good book (I'm not sure if it has the Physics application but oh well). It is called Calculus Made Easy, and it's apparently...

For a first introduction, I remember a lot of you suggested An introduction to mechanics [by] Daniel Kleppner [and] Robert J. Kolenkow. But what about a second introduction with Lagrangian and Hamiltonians? I think I have heard of books like that by Goldstein and Ayra but they don't have answer...

Can anyone recommend some good 'introduction to critical thinking' books?

MNy questions about the QG are vast..i have some math knowledge about GR and only a bit about Regge calculus and Canonical Quantization... 1) if we have the Hamiltonian constraint \bold H =0 then you must have energies (eigenvalues) are all zero¡¡¡ then how does LQG overcome this apparent...

I think most students develop their mathematical background up to classical tensors before digging into the physics of general relativity. I think this approach is good, but once this "Introduction to General Relativity" is finished, then the student should refine his mathematical background...

As the title suggests this thread is intended as a summary of differentiation, it is by no means an attempt at an exhaustive discussion of the topic. A detailed knowledge of limits is not required but is useful, it is assumed that the reader has some knowledge of limits and how to implement...

I urgently need some information like introduction and theory on electropolishing for my project. I have tried searching through the internet but to no avail. Does anyone by chance have some useful links that might aid me? Any help is greatly appreciated.
