Science and Hypothesis

Henri Poincaré’s *Science and Hypothesis* is a landmark exploration of how mathematics, geometry, and physics build on assumptions—not certainties. In clear, engaging prose, Poincaré reveals that many scientific “laws” are freely chosen conventions that make sense of the world, not eternal truths. He examines mathematical reasoning, non-Euclidean geometry, the nature of space and time, classical mechanics, and the role of hypothesis in physics, all while anticipating the revolutionary ideas of relativity. This modern-English edition strips away dated phrasing and translation stiffness, letting Poincaré’s incisive thought shine for today’s readers. Whether you’re a student, a scientist, or a curious mind, this book offers enduring insights into how we know what we know. Part of The Modern Wisdom Library.
