See also:CHARLES AUGUSTIN See also:COULOMB (1736-1806)
, See also:French natural philosopher, was See also:born at See also:Angouleme on the 14th of See also:June 1736
.
He See also:chose the profession of military engineer, spent three years, to the decided injury of his See also:health, at Fort See also:Bourbon, See also:Martinique, and was employed on his return at Rochelle, the Isle of See also:Aix and See also:Cherbourg
.
In 1781 he was stationed permanently at See also:Paris, but on the outbreak of the Revolution in 1789 he resigned his See also:appointment as See also:intendant See also:des eaux et fontaines, and retired to a small See also:estate which he possessed at See also:Blois
.
He was recalled to Paris for a See also:- TIME (0. Eng. Lima, cf. Icel. timi, Swed. timme, hour, Dan. time; from the root also seen in " tide," properly the time of between the flow and ebb of the sea, cf. O. Eng. getidan, to happen, " even-tide," &c.; it is not directly related to Lat. tempus)
- TIME, MEASUREMENT OF
- TIME, STANDARD
time in See also:- ORDER
- ORDER (through Fr. ordre, for earlier ordene, from Lat. ordo, ordinis, rank, service, arrangement; the ultimate source is generally taken to be the root seen in Lat. oriri, rise, arise, begin; cf. " origin ")
- ORDER, HOLY
order to take See also:part in the new determination of weights and See also:measures, which had been decreed by the Revolutionary See also:government
.
Of the See also:National See also:Institute he was one of the first members; and he was appointed inspector of public instruction in 1802
.
But his health was already very feeble, and four years later he died at Paris on the 23rd of See also:August 18o6
.
See also:Coulomb is distinguished in the See also:history alike of See also:mechanics and of See also:electricity and See also:magnetism
.
In 1779 he published an important investigation of the See also:laws of See also:friction (Theorie des See also:machines simples, en ayant regard an frottement de leurs parties et a la roideur des cordages) , which was followed twenty years later by a memoir on fluid resistance
.
In 1785 appeared his Recherches theoriques et experimentales sur la force de torsion et sur l'elasticitedes fils de See also:- METAL
- METAL (through Fr. from Lat. metallum, mine, quarry, adapted from Gr. µATaXAov, in the same sense, probably connected with ,ueraAAdv, to search after, explore, µeTa, after, aAAos, other)
metal, &c
.
This memoir contained a description of different forms of his torsion See also:balance, an See also:instrument used by him with See also:great success for the experimental investigation of the See also:distribution of electricity on surfaces and of the laws of See also:electrical and magnetic See also:action, of the mathematical theory of which he may also be regarded as the founder
.
The See also:practical unit of quantity of electricity, the coulomb, is named after him
