Henri Poincaré
Henri Poincaré was a renowned French mathematician, theoretical physicist, engineer, and philosopher of science. He is often described as a polymath and the last universalist in mathematics due to his foundational contributions in multiple branches of the field. Poincaré made significant advances in algebraic topology, the theory of dynamical systems, and the philosophy of mathematics. He is also known for his work on the threebody problem and the Poincaré conjecture, an important problem in topology that was solved only in the 21st century.

1. Science and Hypothesis
"Science and Hypothesis" is a philosophical exploration of the nature of scientific inquiry, where the author argues that many elements of scientific theory are based on convenient assumptions rather than empirical evidence. The book challenges the notion of absolute truth in science, asserting that many scientific principles are merely working hypotheses that have yet to be disproven. It also discusses the role of mathematics in science, the limitations of inductive reasoning, and the importance of intuition and creativity in scientific discovery.
