Just not in the way you think it is. ► https://www.youtube.com/watch?v=2bZi3Xm9tJE Physics seems complicated, until you realize why it works so well, says physicist Sean Carroll, revealing the basis of the field’s greatest successes: Radical simplicity. Carroll takes us from Newton’s clockwork universe to Laplace’s demon, to Einstein’s spacetime revolution, exploring the historical shockwaves each breakthrough caused. If you’ve wondered how stripping the world down to its simplest parts can reveal deeper truths, this is where that story begins. 00:00:00 Radical simplicity in physics 00:00:55 Chapter 1: The physics of free will 00:04:55 Laplace’s Demon 00:06:27 The clockwork universe paradigm 00:07:41 Determinism and compatibilism 00:08:45 Chapter 2: The invention of spacetime 00:17:30: Einstein’s general theory of relativity 00:24:27 Chapter 3: The quantum revolution 00:28:05 The 2 biggest ideas in physics 00:32:27 Visualizing physics 00:38:17 Quantum field theory 00:46:51 The Higgs boson particle 00:47:28 The standard model of particle physics 00:52:53 The core theory of physics 01:02:03 The measurement problem 01:13:47 Chapter 4: The power of collective genius 01:16:19 A timeline of the theories of physics Read the video transcript ► https://bigthink.com/series/full-interview/physics-of-the-universe/?utm_source=youtube&utm_medium=video&utm_campaign=youtube_description ---------------------------------------------------------------------------------- Go Deeper with Big Think: ►Become a Big Think Member Get exclusive content, early, ad-free access to new releases, and more. https://www.youtube.com/@bigthink/membership/ ►Subscribe to Big Think on Substack Explore content that enlightens, inspires, and transforms. https://bigthinkmedia.substack.com/subscribe/ ►Get Big Think+ for Business Engage learners like never before with high-impact video microlearning from the biggest thinkers in the world. https://bigthink.com/plus/?utm_source=youtube&utm_medium=video&utm_campaign=youtube_description ---------------------------------------------------------------------------------- About Sean Carroll: Dr. Sean Carroll is Homewood Professor of Natural Philosophy — in effect, a joint appointment between physics and philosophy — at Johns Hopkins University in Baltimore, and fractal faculty at the Santa Fe Institute. Most of his career has been spent doing research on cosmology, field theory, and gravitation, looking at topics such as dark matter and dark energy, modified gravity, topological defects, extra dimensions, and violations of fundamental symmetries. These days, his focus has shifted to more foundational questions, both in quantum mechanics (origin of probability, emergence of space and time) and statistical mechanics (entropy and the arrow of time, emergence and causation, dynamics of complexity), bringing a more philosophical dimension to his work.
