The Frog of Abydos 𓆏
will let you know, when there is a content gap yet to be filled.
Jump right to the mathematics of monodromy groups.
This flying carpet is actually a strange attractor of the discrete Lotka-Volterra system. Explore the details, and see an even more astounding version inside.
No mathematical/physical website would be complete without the double pendulum.
The Crab Fractal is a completely new discovery - a Fatou set in polynomial maps that I am currently studying.
The gravitation 3-body a problem. A simple playground for testing numerical integration with the modified midpoint method and others.
Tesselation of the plane, based on a rhomboidal grid. The edges and vertices are at your disposal - give them a drag (and share your results).
An animated Poincare section. A non-autonomous Hamiltonian system gives a time-dependent set of crossing points.
What is "monodromy" anyway?
The Twin Dragon fractal is neatly connected to number systems with complex base. Have you ever wondered what it sounds like?
