What is Augustin-Louis Cauchy?
[[File:Augustin Louis Cauchy.jpg|thumb|right|200px]] '''Augustin-Louis Cauchy''' (21 August 1789 &ndash; 23 May 1857) was a [[France|French]] [[mathematician]] and [[physicist]] who made many important contributions to [[mathematical analysis]] and [[mathematical physics]], including [[Elasticity (physics)|elasticity]]. Importantly, he created [[complex analysis]], which studies complex functions and their properties. Cauchy graduated the [[École Polytechnique]] and [[École des Ponts ParisTech]]. Cauchy did not like mathematicians making assumptions, and he particularly did not like the way that earlier mathematicians, such as [[Euler]] and [[Joseph-Louis Lagrange|Lagrange]], assumed that properties of finite expansions, meaning that we can count the number of terms, also worked for [[series|infinite series]]. Cauchy was able to give examples of where this did not work, and called the assumptions that the earlier mathematicians made, the [[generality of algebra]]. More [[theorem]]s have been named after Cauchy than any other mathematician in history. ==Related pages== *[[Cauchy distribution]] *[[Cauchy's integral formula]] *[[Cauchy sequence]] == References == *{{cite web|last=Freudenthal|first=Hans|title=Cauchy, Augustin-Louis|url=http://www.encyclopedia.com/people/science-and-technology/mathematics-biographies/augustin-louis-cauchy#1|work=Complete Dictionary of Scientific Biography|publisher=Charles Scribner's Sons|access-date=27 November 2017}} {{authority control}} {{DEFAULTSORT:Cauchy, Augustin-Louis}} [[Category:1789 births]] [[Category:1857 deaths]] [[Category:French mathematicians]] [[Category:French theoretical physicists]] {{bio-stub}}
