Despite being dead for more than 2000 years, there are a few of Archimedes' inventions that are still in use to this very day. Most of the electricity for Windsor Castle, one of the King's official residences, comes from a screw pump that is almost identical to the one created by the Greek mathematician. Water from the River Thames turns the screws to generate electricity for the entire castle. Ancient Impossible reveals how many of today's technological achievements were actually developed centuries ago. Colossal monuments, impossible feats of engineering, and technologies so precise they defy reinvention. The ancient world was far more advanced than we ever imagined. We’ll travel through history to reveal a radically different picture of the past, with innovations so far ahead of their time, they’re still in use today.
