In this episode of pplpod, we dive into the extraordinary life and mind of French mathematician and physicist Henri Poincaré, the man often called “the last universalist” for mastering nearly every branch of mathematics in his era. The episode explores how Poincaré laid critical groundwork for both chaos theory and Einstein’s theory of relativity, despite living with poor eyesight, clumsiness, and an unconventional four-hour workday. From investigating deadly mining disasters as an engineer to revolutionizing the study of differential equations, Poincaré embraced the messy unpredictability of the real world instead of forcing nature into neat mathematical formulas. His groundbreaking work on the famous “N-body problem” revealed that even deterministic systems can become impossible to predict over time, helping establish the foundations o ...
