Foundation by Isaac Asimov

This science fiction novel centers around Hari Seldon, a mathematician who has developed a branch of mathematics known as psychohistory. With it, he can predict the future on a large scale. Seldon foresees the imminent fall of the Galactic Empire, which encompasses the entire Milky Way, and a dark age lasting 30,000 years before a second great empire arises. To shorten this period of barbarism, he creates two Foundations at opposite ends of the galaxy. The book follows the first few centuries of the Foundation's existence, focusing on the scientists as they develop new technologies and negotiate with neighboring planets.

The 394th greatest book of all time
