Episode Details

What if the force behind lightning, motors, and light itself is the key to understanding the modern world? In this condensed summary of The Origins Podcast, host Lawrence Krauss breaks down the fifth lecture in his physics series, moving from the weakness of gravity to the overwhelming power of electromagnetism in just minutes instead of the full lecture. He explores Faraday’s field lines, Gauss’s Law, the symmetry of electric and magnetic fields, Maxwell’s unification of electricity and magnetism, and why electromagnetic waves travel at the speed of light. Listeners will come away with a clearer grasp of physics, cosmology, and the science-and-philosophy ideas that explain why the universe works the way it does. Listen now to get the key ideas in minutes.
