Old Research Projects

Gyroscope

This is a simple tutorial example of a driven dissipative dynamical system, which exhibits a period doubling route to chaos. I investigated this system back in 1991 as part of a practical training at university.
Make sure you don't miss the animated attractor.

Complex Ginzburg-Landau Equation Simulator

This is a little Java applet to calculate a model equation for a class of nonlinear dynamic systems - the one dimensional complex Ginzburg-Landau equation. The solution of this equation shows several interesting phenomena like pattern formation, chaotic and intermittend behaviour.
Test it yourself.

Bouncing Balls

This is the result one of my very first projects. I wrote a simple raytracer in Turbo Pascal because I wanted to look into object oriented programming. Back in the early 90ies it took me over a week to render the images for this little animation.
