Poincar�, Jules Henri (1854-1912) was a French scientist who became one of the greatest mathematicians of modern times. He was interested in many aspects of mathematics, physics, and philosophy. Using mathematics as his tool, Poincar� investigated a broad range of natural phenomenon such as the tides, electricity, light, and the motions of the planets. During the late 1800's, he contributed to probability theory, celestial mechanics, and the study of electromagnetic radiation. In addition, many discoveries had been made in science. However, the early 1900's were to bring revolutionary developments in physics. As a scientist, Poincar� was right at the cusp of that major shift.
