Hi, I'm seeking for a software, witch will alow me to easily draw Feynman diagrams. I have currently found: FeynMF: LaTeX package. Not very nice to use, but very good quality diagrams FeynmanDraw: Very primitive WIN software. Not fine diagrams. FeynDiagram: C++ source for drawing...

I'm looking for some excellent references on Feynman diagrams, from an overview of the basics to a description of the relation between the diagrams and the heavy duty mathematics that they represent. Any information would be appreciated.

Our physics teacher gave us some chapter review questions from another book and I don't understand exactly what to do. Here is the question: a) TownA is located 380km[S64oW} of TownB. Draw a displacement vector diagram and a velocity vector diagram to the same scale. (Our book only shows...

Hello, I was quite curious about this one here... If I were asked to draw a structural diagram, for example, of trimethylbutane, where would I put the three branches of methyl. When they don't specify the location of the branches what does one do? I'd normally be expecting something like...

Hey all, I'm a junior in high school and taking physics. My teacher isn't really one of the best teachers, and we do nothing from a textbook, all done from her drawings/lectures from a whiteboard. It's safe to say I'm just about completely lost in that class. We have a test coming up...

Can anyone provide me with information on dispersion diagrams. I am trying to understand how to read/creat them.

Hi If you have asymptote approximations of a Bode plot - do you just find the vector sum of each asymptote to construct the 'full' bode plot? I hope that makes sense Any help much appreciated Jimbo

Richard Feynman in his Physics lectures and diagrams show a free electron emitting a photo and/ or absorbing a photon. He (They?) always show the electron being deflected. My question is if the photon has no mass how can or why does the electron react by being deflected in motion? If it is a...
