When Certainty Broke

This audiobook explores the origins and significance of two fundamental numbers in physics, both produced in a Berlin laboratory within a single year yet vastly different in nature—one measured and the other manufactured. It traces their journeys over the past century, examining how these numbers have shaped scientific understanding and question the ways we interpret experimental results. Through the story of Max Planck and these key constants, the narrative delves into broader themes of measurement, certainty, and the foundations of scientific knowledge.
