In the 19th century, Russia had a great number of writers who would be considered the best ever until today. They included names such as Tolstoj and Gogol. But the best known one is no doubt Dostoevski.
You may know Dostoevski from works such as "Crime and Punishment" or "The Idiot". Dostoevski liked to write a lot, and wrote very long books. His latest major novel was "The Brothers Karamazov". Its an intriguing portrait of a Russian family that includes many dramatic events. It also gives a great insight into the Russian culture of the time. For anyone who is interested in classical literature, this book is a must read. Its now available in a high quality PDF format, totally free.

Caerfai Chemical Simulation is a simple tool that is trying to simulate chemical reactions.
The model is much too simple to be useful, but it gives some nice images and animations. Source is included and offers a nice starting point for similar endevours.
Every atom in the simulation is a moving ball which bounces on other atoms and the edges of the window. Atoms can bind to each other, similar to how things work in reality. Well start out with just radicals and build molecules from there. In reality, this is pretty much where it stops, but I break up the molecules everytime they bounce, in order to create more interesting structures. Less chemical, but more fun.
Breaking up the molecules when in reality they would break, would complicate the program a lot beyond the current few hundred lines and anyway, the reaction would occur almost never, as it happens in reality (but there the molecules go so fast that it seems quite quickly, especially if your sleeves have gotten on fire)
