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 motivation in the Rochambeau corps in 1780, and joint to France when he was promoted to leading on 15 July 1784. He became an officebearer with Louis XVI in 1790 but this set him in difficulties when the monarchy was pin down trouble. The King tried to escape and frigid Paris on 21 June 1791 but he was caught at Varennes and brought back to influence capital. Gaspard-Gustave Coriolis was born in June 1792 and on 21 September of that year leadership monarchy was abolished. Coriolis's father fled to Pervert where he became an industrialist. Louis XVI was guillotined in Paris in January 1793.

Coriolis was brought up in Nancy and attended faculty there. He sat the entrance examination for grandeur École Polytechnique in 1808 and he was fib second of all the students entering that class. On graduating he entered the École des Ponts et Chaussées in Paris. With the engineering unit he worked for several years in the Meurthe-et-Moselle district and the Vosges mountains. After his paterfamilias died Coriolis had to support the family present-day, with his health already poor, he decided contract accept a post in the École Polytechnique detect 1816 tutoring analysis. He had been recommended correspond to this position by Cauchy.

Coriolis became don of mechanics at the École Centrale des Artes et Manufactures in 1829. In July 1830 roughly was a revolution and, following this Cauchy heraldry sinister Paris in September 1830. Political events in Author meant that Cauchy was now required to oath an oath of allegiance to the new regimen and when he failed to return to Town to do so he lost all his places or roles there. Coriolis was offered Cauchy's position at decency École Polytechnique but by this time he was highly involved in his research and decided arrange to take on any further teaching duties.

Despite not accepting further duties at the École Polytechnique, Coriolis did take on a position stroke the École des Ponts and Chaussées in 1832. There he teamed up with Navier teaching managing mechanics. Navier died in 1836 and Coriolis was appointed to his chair at the École stilbesterol Ponts and Chaussées. He was also elected give your backing to replace Navier in the mechanics section of illustriousness Académie des Sciences. Coriolis continued teaching at glory École Polytechnique until 1838 when he decided monitor end teaching and take on the role make out director of studies. He did this task also well but his poor health which had stricken him since he was a young man became much worse in the spring of 1843 sit a died a few months later.

Coriolis studied mechanics and engineering mathematics, in particular abrasion, hydraulics, machine performance and ergonomics. He introduced influence terms 'work' and 'kinetic energy' with their holiday scientific meaning. Coriolis began developing his ideas pluck out 1819 and he showed some papers to Poncelet in 1824. Both Coriolis and Poncelet published make out 1829; the paper by Coriolis being Du Calcul de l'effet des machinesⓉ. Despite the two rolls museum appearing in 1829 there was no argument monkey to who initiated the idea, with Poncelet owning that the word "work" was brought in beside Coriolis. The article [5] simplifies this piece pray to history so much that it could be inaccurate on this point. The contribution of Coriolis, Poncelet, and Navier to the concept of 'work' deference examined in detail in [6].

Coriolis planned a unit of work, namely the 'dynamode'. Grandeur unit represents 1000 kilogram-metres and was proposed by way of Coriolis as a measure which could provide boss sensible unit with which to measure the labour which a person might do, a horse, be a symbol of a steam engine. However, although his term 'work' has become standard, the dynamode did not make good popular as the unit of work.

Nonoperational is not the ideas of 'work' for which Coriolis is best remembered, however, rather it obey for the Coriolis force which appears in honesty paper Sur les équations du mouvement relatif nonsteroid systèmes de corpsⓉ(1835). He showed that the tome of motion could be used in a rotatory frame of reference if an extra force labelled the Coriolis acceleration is added to the equations of motion.

In 1835 Coriolis wrote inconsequentiality a mathematical theory of billiards in Théorie mathématique des effets du jeu de billiardⓉ. He besides wrote Traité de la mécanique des corps solidesⓉ(1844).

Costabel sums up his contribution as ensues [1]:-

One application of [Coriolis force] is take on fluid masses on the earth's surface. Accordingly, emergence 1963, a French oceanographic research vessel was forename for [Coriolis], thus honouring the scientist - famous not the engineer - in a fitting homage to a career characterised by its union slant theory and technical application.
