foundation - choose a jigsaw puzzle to solve

The Foundation series is a science fiction book series written by American author Isaac Asimov. For nearly thirty years, the series was a trilogy : Foundation, Foundation and Empire , and Second Foundation. It won the one- time Hugo Award for "Best All- Time Series " in 1966 . Asimov began adding to the series in 1981, with two sequels: Foundation's Edge, Foundation and Earth , and two prequels: Prelude to Foundation, Forward the Foundation. The additions made reference to events in Asimov's Robot and Empire series , indicating that they were also set in the same fictional universe . The premise of the series is that the mathematician Hari Seldon spent his life developing a branch of mathematics known as psychohistory, a concept of mathematical sociology . Using the laws of mass action, it can predict the future , but only 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. Seldon's calculations also show there is a way to limit this interregnum to just one thousand years. To ensure the more favorable outcome and reduce human misery during the intervening period, Seldon creates the Foundation - a group of talented artisans and engineers positioned at the twinned extreme ends of the galaxy - to preserve and expand on humanity's collective knowledge , and thus become the foundation for the accelerated resurgence of this new galactic empire .
