A century ago, Albert Einstein rewrote our understanding of physics with his Theory of General Relativity. Our intuitive ideas about space, time, mass, and gravity turned out to be wrong. Find out how this masterwork changed our understanding of how the universe works and why you can thank Einstein whenever you turn on your GPS. Also, high-profile experiments looking for gravitational waves and for black holes will put the theories of the German genius to the test – will they pass? And why the story of a box, a Geiger counter, and a zombie cat made Einstein and his friend Erwin Schrödinger uneasy about the quantum physics revolution. Guests: •  Jeffrey Bennett – Astronomer, author of What Is Relativity?: An Intuitive Introduction to Einstein’s Ideas, and Why They Matter •  Beverly Berger – Theoretical physicist and the Secretary for the International Society on General Relativity and Gravitation •  Hiawatha Bray – Technology reporter, Boston Globe, author of You Are Here: From the Compass to GPS, the History and Future of How We Find Ourselves • Paul Halpern – Physicist at the University of the Sciences in Philadelphia, author of Einstein’s Dice and Schrödinger’s Cat: How Two Great Minds Battled Quantum Randomness to Create a Unified Theory of Physics Learn more about your ad choices.
