In my 4th year of University I had what would become one of my favorite courses, Simulation, where, as a final project, each student (or team of students) should choose a real problematic situation and create a simulation model (with AnyLogic). I choose something I was familiar with, the never-ending queue of the elevators of the University building, I asked for the blueprints and simulate several alternatives to find which was the best.

When I was at my 3rd year of University I have a complete subject about Ordinary Differential Equations and other similar topics. For that course we used Wolfram Mathematica throughout the year and I asked the teacher whether I can do it with Python, here you can see the results.
