A no-nonsense description of quantum mechanics with no maths or philosophy. The concepts are explained with
animations, which are mainly computer simulations of electrons.
An interactive simulation of a Mars Lander trying to land on Mars. The term "interactive" here means that
you have to write the software, in Javascript, that will land the probe.
A simple demo of a simulation of an atmosphere. It looks quite cool, but there's not a lot you can
do with it yet, and the physics isn't yet all that accurate.
