Henri Poincare's Birthday

Jules Henri Poincaré was born on April 29th, 1854 (died July 17, 1912).  He was a French mathematician, physicist and astronomer who was also a gifted interpreter of science to the public. His Poincaré Conjecture holds that if any loop in a given three-dimensional space can be shrunk to a point, the space is equivalent to a sphere. Its proof remains an unsolved problem in topology. He influenced cosmogony, relativity, and topology. In applied mathematics he also studied optics, electricity, telegraphy, capillarity, elasticity, thermodynamics, potential theory, quantum theory, and cosmology. He is often described as the last universalist in mathematics. He studied the three-body-problem in celestial mechanics, and theories of light and electromagnetic waves. He was a co-discoverer (with Albert Einstein and Hendrik Lorentz) of the special theory of relativity.  The Institut Henri Poincare in Paris, France is named in his honor.
