Gustave-Gaspard Coriolis
(1792–1843) French physicist
Coriolis, a Parisian by birth, studied and taught at the Ecole Polytechnique, becoming assistant professor of analysis and mechanics in 1816. He was the first to give precise definitions of work and kinetic energy in his work Du calcul de l'effet des machines (1829; On the Calculation of Mathematical Action) and he particularly studied the apparent effect of a change in the coordinate system on these quantities.
From this latter research grew his most famous discovery. In 1835, while studying rotating coordinate systems, he arrived at the idea of the Coriolis force. This is an inertial force which acts on a rotating surface at right angles to its direction of motion causing a body to follow a curved path instead of a straight line. This force is of particular significance to astrophysics, ballistics, and to earth sciences, particularly meteorology and oceanography. It affects terrestrial air and sea currents; currents moving away from the equator will have a greater eastward velocity than the ground underneath them, and so will appear to be deflected. The idea was developed independently by William Ferrel in America.
In 1838 Coriolis stopped teaching and became director of studies at the Polytechnique, but his poor he

Biography
Gaspard-Gustave de Coriolis's father was Jean-Baptiste-Elzéar Coriolis and his mother was Marie-Sophie de Maillet. His father became a sub-lieutenant in the Bourbonnais regiment in 1773, fought in the American campaign in the Rochambeau corps in 1780, and returned to France when he was promoted to captain on 15 July 1784. He became an officer with Louis XVI in 1790 but this put him in difficulties when the monarchy was in trouble. The King tried to escape and fled Paris on 21 June 1791 but he was caught at Varennes and brought back to the capital. Gaspard-Gustave Coriolis was born in June 1792 and on 21 September of that year the monarchy was abolished. Coriolis's father fled to Nancy where he became an industrialist. Louis XVI was guillotined in Paris in January 1793.Coriolis was brought up in Nancy and attended school there. He sat the entrance examination for the École Polytechnique in 1808 and he was placed second of all the students entering that year. On graduating he entered the École des Ponts et Chaussées in Paris. With the engineering corps he worked for several years in the Meurthe-et-Moselle district and the Vosges mountains. After his father died Coriolis had to support the family and, with his health already poor, he
