I am interested in special relativity . Okay , the thing is I am currently an undergraduate in electrical engineering . I had a basic course on special relativity . I don't know about Minkowski space and stuff . I was thinking of starting with simple stuff in relativity. You are saying that as soon as tensor thing is done , you can easily implement relativity .
I basically need some project ideas to work on . It can be anything existing or anything new . Can you provide me with some ideas to work upon . On Wednesday, May 14, 2014 12:54:47 PM UTC+5:30, F.
