Welcome

at the site of Ronald Koster.

I use this site to demonstrate some features possible using static HTML pages mainly. Furthermore I use this site to publish information I find useful. Here is a list of some of my publications so far:

Famous statements;
Some jokes;
Two very nice Dutch card games: Bonaken and Kraken (in Dutch);
What is spacetime? Minkowski's spacetime concept explained;
Is space travel possible? Have we ever been visited by aliens? A scientific approach (rocket dynamics) to this question.
A well-know problem from cosmology, Olber's paradox, solved!
Another well know problem, The Arrow of Time, solved!

Would you like to see more photos?

Eerbetoon aan Sandy.
