# Henri Poincare

Apart from being a well-known mathematician, Jules Henri Poincare also indulged in the study of philosophy. He learned much during his lifetime and was later called ‘Polymath’ for his strong foothold in a wide array of subjects. As a mathematician, he discovered and created the field of topology, and studied the continuity of shapes. This would later help him answer a crucial question based on the solar system and its stability. He also contributed to the field of nonlinear systems and went on to describe the many properties of deterministic chaos. He was a great philosopher of science and appreciated works that were largely based on celestial mechanics. The first person to present the ‘Lorentz Transformations’, Henri Poincare was a pioneer in the field of special relativity and went on to influence a long list of mathematicians who also became popular in this field. With his colossal contribution and religious dedication to the subject, Henri Poincare became a legend, and a special group used in physics and mathematics called the ‘Poincare Group’ was named after him.

**Childhood And Early Life**

^{th}April 1854 to Leon Poincare and Eugenie Launois. He was born in the town of Nancy into an affluent family and his father was a professor of Medicine at the University of Nancy. Poincare was born into a family of repute and celebrity status. Poincare’s first cousin, Raymond Poincare would become the president of France, serving presidential term between the years 1913 to 1920.

**Career**

^{nd}king of Sweden, awarded Poincare when he succeeded in finding out the solution to the problem of gauging the stability of the solar system. This was a classic example of classical mechanics, and eventually led to the discovery of the ‘Theory of Chaos’. The theory of ‘Special Relativity’ was co-founded by Henri Poincare along with Hendrik Lorentz and Albert Einstein.

**Death And Legacy**

^{th}1912 at the age of 58. Poincare’s works went on to make history all over the world. He wrote several books which led to the continuation of his fabled legacy. His works on thermodynamics, quantum physics, optics and fluid mechanics inspired a long line of successors in the fields of physics and mathematics, like Marie Curie.
