Extractions: Galois Evariste (français, 1811-1832) C'était un brillant étudiant mais son caractère tempétueux lui empêcha à deux reprises l'entrée à l'école polytechnique. A 16 ans, trop brillant sans doute, et sûrement un peu brouillon, il fût incompris par les mathématiciens de l'époque qui rejetèrent les travaux qu'il voulait présenter à l'académie des sciences. Ses idées républicaines l'on conduit en prison d'où il sortit malade quelques mois plus tard. Galois avait 20 ans quand il s'éprendra d'une femme pour laquelle il dût accepter une provocation en duel où il trouva la mort. En , les travaux de Galois ont été considérés, ce qui a fait connaître son traité d'algèbre. Il y a prouvé l'impossibilité de résoudre par radicaux les équations de degré supérieur ou égal à 5 (hormis bien évidemment les cas triviaux), complétant ainsi les travaux d'Abel. Retour

Extractions: EVARISTE GALOIS "Oko³o roku 1830 na firmamencie matematyki zab³ys³a nies³ychanej jasno¶ci gwiazda: Evariste Galois" - tak okre¶li³ niemiecki matematyk Feliks Klein pojawienie siê prawdziwego geniusza matematycznego, który pomimo m³odego wieku uzyska³ wyniki gwarantuj±ce mu miejsce w¶ród czo³owych twórców wspó³czesnej algebry i przyprawiaj±ce o palpitacjê serca studentów matematyki, którzy nie do¶æ, ¿e musz± siê tego nauczyæ, to jeszcze wypada³oby to zrozumieæ. Galois urodzi³ siê w 1811 roku w Bourg-la-Reine ko³o Pary¿a. Jego ojciec by³ nauczycielem szko³y podstawowej. W roku 1823 Evariste opu¶ci³ dom rodzinny, by rozpocz±æ naukê w klasie czwartej Liceum Ludwika Wielkiego. Maj±c 15 lat przypadkowo zainteresowa³ siê nieobowi±zkow± w klasie retoryki matematyk± i ju¿ w kilka tygodni po przeczytaniu geometrii Legendre'a zacz±³ formu³owaæ w³asne pogl±dy. Galois debiutowa³ naukowo na ³amach czasopisma matematycznego jako uczeñ, w znacznie za¶ obszerniejszej pracy sformu³owa³ wyniki swoich badañ i przes³a³ je Akademii Nauk. Niestety, dla matematyków, na szczê¶cie dla studentów, rêkopis ten, zawieraj±cy bezspornie najgenialniejsze idee stulecia, zagin±³. Po wst±pieniu na tron Ludwika Filipa Galois bierze aktywny udzia³ w walce politycznej, nale¿±c do lewicowego republikañskiego stronnictwa "Przyjació³ Ludu". Za publiczne wyst±pienie przeciwko re¿imowi królewskiemu dwukrotnie trafia do wiêzienia. Tam otrzymuje pismo z Akademii Nauk, odpowied¼ na powtórnie wys³any rêkopis. Wybitny matematyk Poisson, który referowa³ tê pracê, opatrzy³ j± nastêpuj±c± uwag±: "... nie jeste¶my nawet w stanie uchwyciæ my¶li przewodniej autora". Prawie bezpo¶rednio po odzyskaniu wolno¶ci Galois zgin±³ w pojedynku, sprowokowany przez politycznych przeciwników.

Extractions: EVARISTE GALOIS Evariste Galois, a Frenchman, b. Oct. 25, 1811, d. May 31, 1832, made significant contributions to several branches of mathematics, including algebra, number theory, and group theory. In 1829 he published his first paper on continued fractions, followed by a paper that dealt with the impossibility of solving the general quintic (fifth-degree) EQUATION by algebraic means alone. This led to Galois theory, a branch of mathematics dealing with the general solution of equations. Galois was killed in a duel. Author: Arthur Schlissel

Extractions: Evariste Galois var fransk matematiker född 1811 och död 1832 Har gett det engelska namnet åt kropp Galois Field Evariste Galois far var borgmästare i Paris och han fick god utbildning. Han var duktig och fick priser men år 1826 fick han trots det gå om ett år för brister i retorik -ämnet. Dessa brister kan ha varit det som orsakade att han hade svårt att förklara sina geniala insikter inom matematiken. 30 maj 1832 deltog han i en duell med Perscheux d'Herbinville om en kvinna, Stephanie. Galois blev svårt skadad och dog den 2 juni. Efter hans död hittades anteckningar där många tros ha skrivits natten innan duellen som ett sätt att bevara de kunskaper som Galois skaffat sig. Först 1843 presenterades de för allmänheten av Liouville . Det är möjligt att andra som kan ha sett dem som Gauss och Jacobi inte insåg anteckningarnas stora innehåll.

Evariste Galois. Finally Evariste Galois (1811 1832) showed that thereis no algebraic formula for solving equations of degree five or more.
http://www.math.utah.edu/lab/math/history/galois.html

Extractions: Methods for solving quadratic equation were known to many ancient peoples, including the Babylonian, Chinese and Hindu civilizations. Whether or not they had the quadratic formula, they had the main principle (completion of the square). After much struggle, Scipio del Ferro (1465 1526) found a formula for solutions of the cubic equation. His work was never published and was communicated to a few friends. Nonetheless, the fact that he had solved the problem became known, and Tartaglia (1500 1557) rediscovered the formula in 1535. He too kept his result secret but was tricked into revealing it by Cardano (1501 1576). Cardano also discovered a formula for the quartic equation. For 350 years no further progress was made. Finally Evariste Galois (1811 1832) showed that there is no algebraic formula for solving equations of degree five or more. Galois' work relies on the theory of groups.

By order of Augustus he undertook an expedition to Arabia Felix, with disastrous results. The troops suffered greatly from disease, heat, want of water and the obstinate resistance of the inhabitants. The treachery of a foreign guide also added to his difficulties. After six months Gallus was obliged to return to Alexandria, having lost the greater part of his force. He was a friend of the geographer Strabo, who gives an account of the expedition (xvi. pp. 780-782; see also Dió Cassius liii. 29; Pliny, Nat. Hist. vi. 32; C. Merivale, Hist. of the Romans under the Empire, ch. ~4; H. Kruger, Der Feidzug des A. G. nach dem giucklichen Arabien, 1862). He has been identified with the Aelius Gallus frequently quoted by Galen, whose rem~dies are stated to have been used with success in an Arabian expedition.

http://www-groups.dcs.st-and.ac.uk/~history/Mathematicians/Galois.html

Extractions: Evariste Galois ' father Nicholas Gabriel Galois and his mother Adelaide Marie Demante were both intelligent and well educated in philosophy, classical literature and religion. However there is no sign of any mathematical ability in any of Galois' family. His mother served as Galois' sole teacher until he was 12 years old. She taught him Greek, Latin and religion where she imparted her own scepticism to her son. Galois' father was an important man in the community and in 1815 he was elected mayor of Bourg-la-Reine. You can see a map of Paris in the 19th Century, showing Bourg-la-Reine. The starting point of the historical events which were to play a major role in Galois' life is surely the storming of the Bastille on 14 July 1789. From this point the monarchy of Louis 16th was in major difficulties as the majority of Frenchmen composed their differences and united behind an attempt to destroy the privileged establishment of the church and the state. Despite attempts at compromise Louis 16th was tried after attempting to flee the country. Following the execution of the King on 21 January 1793 there followed a reign of terror with many political trials. By the end of 1793 there were 4595 political prisoners held in Paris. However France began to have better times as their armies, under the command of Napoleon Bonaparte, won victory after victory.

Extractions: "Morto jovem matemático na idade de 20 anos, assassinado brutalmente num duelo de armas duvidoso". Assim deixou Evariste Galois (1811+21=1832) um mundo de luto por não ter conseguido entender sua genialidade precoce. Bebida, mulheres, política e matemática, Galois contém uma história de vida em que certamente daria para escrever uma novela. Galois nasceu em Bourg-la-Reine, França, no seio de uma família que, apesar de não ser rica, propiciou à criança uma infância sadia. Aos doze anos ingressa na escola e já começa a demonstrar suas primeiras afinidades com a matemática e a política. Naquela época Napoleão há havia sido deposto e restaurada a monarquia, porém o jovem, já tendo decidido pela república, em um ato de homenagem na sua escola à sua majestade deixou propositadamente cair a taça na hora do brinde; em outra oportunidade havia soltado um forte arrôto na presença de um côro de estudantes que iriam se apresentar ao rei - apenas ensaios do que estava por vir. Os tempos vão passando e Galois vai se aprofundando mais e mais na política, revelando ser um republicano nato. Ao mesmo tempo vai ensaiando o momento de ingressar na célebre Écòle Polytechnique, fundada pelo próprio Napoleão e responsável pela criação dos maiores e melhores engenheiros da França. Prepara-se para os exames mas não consegue lograr êxito - seu despreparo nas outras matérias o afastam durante um tempo do seu sonho - Galois tinha 16 anos. Sua reprovação não o impede de tentar mais uma vez o ingresso na Universidade. Então decide estudar com afinco, se preparando de verdade e, é claro, não deixando de frequentar as conferências da sociedade "Amigos do Povo", e mesmo as aulas da Polytechnique como aluno-ouvinte. Estas aulas seriam de muita valia para a Teoria matemática que estava descobrindo - a Teoria dos Grupos.
