Does Mathematica use first-order or second-order unification?

How to draw feynman diagrams in mathematica? [help!]?

• My physics professor wants my particle physics class to write a program in Mathematica to draw feynman diagrams (lowest order ones, like a simpler FeynArts). I've NEVER programmed in mathematica before (I have in C++). I've only ever used it for my calculus classes. This project is due Monday by noon. I've been putting it off for a few days because I just couldn't figure it out, and now it's here and I still don't know what to do, and I'm freaking out. I've already went to my professor for help, but he told me just to search for help tutorials on wolfram, which I did but still can't find anything relevant. And now it's too late to go back to him for help. PLEASE HELP! Does anyone know how to do this? Or know of any video tutorials that can guide me through this? I know how to calculate and draw feynman diagrams by hand, I just don't know how to use mathematica to do it! D: Help :(

• Answer:

  Hmm, I'm afraid you won't make it, since it sounds like a rather complex assignment, but the two most important Mathematica functions you will probably needs are Module and Graphics. Type either one of those in Mathematica and press F1 for a detailed help on how to use them. Basically, Module will allow you to write functions as you would normally do in C++ and Graphics allows you to make graphical objects, which you probably need for making the picture. In the help of Graphics there should be links to graphical object, such as Line, Disk, etc... I hope you can get an extension.
