Welcome in Rutherford scattering simulation. 
Author: Justyna Ilczuk also known as attero
License: MIT should be okay ^^

To run simulation you need python 2.7 and pygame - library for python. Both are easy to download and free to use.

If you have those already installed just run "python2 rutherford.py" in command line or whatever you do to run applications on your OS.

Have fun :)
