Foundation

The world of the Foundation series takes place over twenty thousand years in the future, when humanity has colonized the entire Galaxy and created a unified empire encompassing all human-inhabited planets. It is based on the premise that the brilliant mathematician Hari Seldon developed theories to predict the behavior of large masses of people over long periods of time. These theories laid the foundation for a science called psychohistory, which uses mathematics to reveal the future. It assumes that while the behavior of individuals is too free and unpredictable, the behavior of large masses of people can be predicted through mathematical simulations.
