This episode explores the life and groundbreaking work of Henri Poincaré, a French polymath renowned for his contributions to mathematics, physics, and the philosophy of science. Known as "The Last Universalist," Poincaré made foundational advances in dynamical systems, topology, and theoretical physics. His work on the n-body problem introduced the early ideas of chaos theory, and he laid the groundwork for algebraic topology through concepts like the fundamental group. In physics, he anticipated many principles of special relativity and contributed to the development of the Lorentz transformations. Beyond science, Poincaré also reflected deeply on the nature of knowledge and the role of creativity in discovery, making him a rare blend of scientist and philosopher. His legacy endures as a model of interdisciplinary brilliance and visionary thought.
