# From Pythagoras to Einstein: The Geometry of Space and Time (General audience talk). Faculty of Mathematics Public Lectures : University of Waterloo. March 9, 2015

Invited Talk

From Pythagoras to Einstein: The Geometry of Space and Time 6:00 p.m. - 7:00 p.m. Earth Sciences Museum EIT 1015 Pythagoras was an ancient Greek who was not only a mathematician, but also a religious cult leader. He and his followers believed that the key to unlocking the mysteries of the universe was hidden somewhere inside mathematics and geometry. Crazy, right? Well, it turns out he was right. Thousands of years later, based on the work of the mathematicians Gauss and Riemann, Einstein discovered a hidden geometry of the universe. Starting with the Rule of Pythagoras for right triangles, we’ll survey the ideas which led to Einstein’s historic discovery and how it relates to black holes, the Big Bang, and the unification of space and time.
