About
With these animations, I am trying to show that mathematics and physics can be beautiful. They are all based on real models in physics and maths, typically describing the evolution in time of some system: a particle or a wave in a closed domain, a growing interface, a population of animals.
Thanks to all those sending me suggestions for other simulations. I will try to implement some of them. I am also making available the code used to create some of these videos, once I have tested it in a number of cases, so you have the possibility of downloading the code and modifying it yourself.
