Feynman Definition and 617 Threads

Hi! I need some help with latex. I need to draw Feynman diagrams and it seems that the package feynmfm relies on Metafont, which I really don't even have the slightest idea as how to use it. Anyway, I tried to find a good tutorial on the subject (metafont) but it looks like i will need some...

Has anyone read the Feynman Lectues? Is it worth getting if you are looking to further establish a good grasp of the fundamentals?

I have posted a question on the Tutorial subforum because there was already a thread on that subject but I figured that people here may be more likely to be able to help me out https://www.physicsforums.com/showthread.php?p=1313121#post1313121 Thanks! Patrick

I was just reading the Feynman Lectures on Physics when Feynman discussed virtual work. Unfortunately, I found his explanation somewhat confusing. The following are the three examples Feynman uses in order to illustrate the principle of virtual work. 1. 2. 3. I'm trying to...

Does anyone know where to download the Feynman lectures at? Thanks

Have anyone read "Surely You're Joking Mr. Feynman"?? Have anyone read "Surely You're Joking Mr. Feynman"?? What did you think of it? I only read about half and the the library wanted it back.. But I thought the first half was good, and a little bit funny too..

Homework Statement I am pretty sure it's been done many times before, but I can't seem to figure it out: Consider the collision 1 + 2 -> 3 + 4 in the lab frame (2 at rest), with particles 3 and 4 massless. Derive the forumla for the differential cross section Homework Equations We have...

Greetings all, If you are like me you have a profound respect and admiration for Richard Feynman, the father of QED. Rarely does humanity produce such a brilliant mind and with such an affable personality to boot. Below is a link where you will find several Caltech lectures, eBooks and...

I have some quotes from various books I have read recently, that I would love to hear your thoughts on: Richard Feynman: "All these [chemical] rules were ultimately explained in principle by quantum mechanics, so that theoretical chemistry is in fact physics. On the other hand, it must be...

I have always seen these books in the stores, and such, and they're 100 on amazon (which is a heck of a lot better than B&N) and i want them, but then again they'll probably shoot right over my head. I'm working through my first year of high-school physics. I have read quite a few books on...

Dear PF, I would like to thank you for existence of Physics forums since it appears very helpful. Dear PF, I was reading one paper and trying to derive Feynman rules for some vertices, but I could not get the same result as given in paper, as a guideline I use ‘t Hooft’s diagrammar and the...

Amazon has a list of 100 bestseller books in physics category. this includes popularizations, biographies, textbooks, Carl Sagan, Brian Greene, intelligent design, iffy-physics-of-the-supernatural, physics cartoons and comedy, ANYTHING if it has a connection with physics*. So the competition is...

OK. I've googled for about an hour yesterday and couldn't find where to get "Think different " poster feat. Feynman. :frown: there are two actually, the one where Feynman is in his sixties is really hard to find. :mad: any ideas on where I can buy it?

I swear this book does not actually exist. Well, unless I'm willing to spend between $300 and $1200 (no, that's not a typo). Am I correct in my suspicion that there was only a single printing of the text back in '65? Does anyone actually have a copy?

On page 92 (Figure 58) Feynman states: "The amplitude for a coupling is a number that I will call j; it is about negative .1 for the electron (this number is sometimes called the "charge"). Charge?? I don't get it. Would appreciate an explanation?

I've been given a small project to ease me into life as a PhD student and part of it involves working out Feynman rules for scalar bosons coupling to gauge bosons. I've been reading through Peskin and Schroder Chapter 9 and want to clarify if I've got my understanding right of how to do it...

I'm far from well versed in physics, but I'm trying to understand something about a Feynman diagram I saw. The diagram shows an electron and positron annihilating, and producing a quark/anti-quark pair and a gluon. I recently saw a special on the discovery channel that said matter/anti-matter...

Hello! The next academical year I am going to study physics on the university and I want to prepare for the challege. I am planing to buy the Feynman lectures of physics. At amazon.com there is three sets avalible, from 2005, form 1989 and from 1970. I can't choose, I don't know which is the...

does anyone know where i can get a copy of this? i saw it a few years ago but didnt think to record it.

Could anyone direct me to a coherent tutorial for drawing simple Feynman diagrams in Latex (I use TeXnicCentre) using the Feynmf package? The only ones I've found are rather complicated, given that I don't have a huge deal of experience with the writing of lengthy 'tex. Cheers, guys. [If this...

pronunciation of "Feynman" How is the "ey" in "Feynman" pronounced: 1. "ei" like in the word "hey" 2. "ai" like in the word "hi" 3. neither of 1,2.

Hey, this is a pretty simple induction problem, but I suck at induction and I think I'm missing something really obvious here, though trying to figure it out whilst having a pretty bad cold isn't much of a good idea. The identity \frac{1}{A_1\cdots A_n}=\int_0^1 dx_1\cdots dx_n \delta...

The National Geographic Channel has started airing its docu/recreation of the Challenger disaster and the consequent investigation. I watched most of it tonight and was interested to see that they decided to make Feynman a major character in the show. That in contrast to another special about...

Hey everyone, I found an AWSOME site that broadcasts science programs for free over the internet. http://www.vega.org.uk/index.php" If you go to Science Programmes > Vega Science Lectures > Richard Feynman you will find the lectures that he gave at the University of Auckland (New...

In one of his lectures Richard Feynman describes the effect of a magnetic field on an electron. In doing this he describes the magnetic field as being made up of many photons. If a photon is an oscillating electromagnetic field how can it be just a magnetic field also ?

Hey, I am currently in 11th grade. Were studying Mechanics from Resnick & Halliday 7th edition. I'd like to know If Feynman does a better job with mechanics? (Volume one). Next year , were going to study electromagnetism, and I was planning on reading Feynman Vol II in the summer, should I or...

What are the Feynman rules for phi to the sixth theory? Can anyone please help? Peskin and Schroeder does phi ^ 4th... I can't help thinking the derivation is the same for phi to the sixth, and that the rules are the same. Could that be correct? Thanks so much for your time, Job...

How is it pronounced? The Wikipedia article (http://en.wikipedia.org/wiki/Richard_Feynman) says it is pronounced like "Fine-man". This has been bugging me for some time.

Heres a new website dedicated to the hero of all physics geeks: Richard P. Feynman.The site features many Feynman articles like his lectures, anecdotes, jokes, stories etc.. other resources like jokes and daily news feed and others make it a good site to kill time or learn some random stuff...

Hi I have to draw a Feynman diagram for the following reaction: K^{*+} \rightarrow K^0 + \pi^+ The K^{*+}-meson is composed of an u and an anti-s quark, the K^0-meson is composed of a d and an anti-s quark, and the \pi^+-meson is composed of an u and an anti-d quark. I have drawn...

Hey, I was wandering if anyone knew if the Feynman diagrams could be created in Latex or in threads like this? If not then maybe it would be an interesting development avenue...

i.e. the Douglas Robb memorial lectures from Auckland University, They're available streamed here: http://www.vega.org.uk/series/lectures/feynman/ But i want to download the files. Can i grab them anywhere?

In doing my \phi^{3} theory I didn't know exactly how to count the number of loops in a diagram given the number of vertices, internal and external lines. Is there a general algorithm in doing this? What if we have more than one interaction vertex (e.g. the Standard Model)? PS. What does it...

Ok folks. Now to waste your time on a idiotic question.. Did Feynman know how to drive?

Are the "Feynman Lectures on Physics" books good? Are the "Feynman Lectures on Physics" books good? I'm going into my junior year next year and wonder if these books are any good to study over the summer?

For those of you who live in the USA and still use snail mail... The US Postal Service is issuing a set of four 37-cent "American Scientists" postage stamps next week. They picture Richard Feynman, Josiah Willard Gibbs, John von Neumann and Barbara McClintock. They should be available at most...

Ok - so essentially the Feynman propogator is a Green function solved for a point source - i.e a delta function in 3 dims. My question is more mathematical. When you solve for the Green Function you assume (id-m)G(x,x') = delta(x-x') (roughly) Then solving this...

I went to a book signing tonight for a new volume of letters to and from Richard Feynman entitled Perfectly Reasonable Deviations from the Beaten Track. The book is edited by Michelle Feynman, Richard's daughter. She gave a brief introduction to the book and then read several of the letters...

If someone is interested in live lectures given by Richard Feynman on introductory QED, just check out the site in my journal https://www.physicsforums.com/journal.php?s=&journalid=13790&action=view#LIVE%20FEYNMAN%20QED-LECTURES regards marlon

I'm interested in learning the fundamentals of physics, likely from Feynman's text. However, I'd like to know if there's anything in the Feynman that's been disproved since it was published as I'd hate to have to unlearn anything I didn't have to. Thanks.

Is there a systematical way to count all the possible feynman diagram with vertices less than or equal to n...

I have been researching Feynman and his diagram and really can't find much on the Diagram itself. Could anyone tell me the mathematics and other concepts behind it in excruciating detail? Or at least a site I can find it? Thanks

I just started reading The Character of Physical Law and I have to say I got goose bumps from some of the things I have read. I would like to share a few lines that I am sure a lot of you have either heard or read yourself and maybe you too can share your first experience with this fellow...

Hi , i am very eager to listen to feyman lectures on physics. i tried to listen to some at http://www.vega.org.uk/series/lectures/feynman/index.php . But i could not , as there is some problem with the site. So , can anyone suggest an alternate site or if anyone has the lectures with...

so I herd that atpms are actuall blob like particles insted of hard crystal orb like things but are quarks the same way? are quarks like blobs too?

I'm in grade 11 physics, and I was wondering if I'd be able to get through the Feynman lectures without being totally confused. As a side questions, would those lectures give me an insight on a broad range of physics topics? That is what I'm looking for right now.
