Theoretical physics with sympy

I will introduce the basic functionalities of the sympy package to do symbolic computing, with a special focus on vector and matrix operations. Then, I'll briefly explain a real-world model from the description of 2D layered magnetic materials and use sympy to deal with the resulting expressions. We'll evaluate those expressions to visualize the results of the model and obtain a numerical estimate of a transition point. The aim of this talk is to give a light-hearted introduction into the world of symbolic computing to someone who has more fun working with computers than pen and paper.
