Janos Bolyai (Kalozsvar, oggi Cluj, 1802 - Marosvararhely 1860) Fu uno dei fondatori della geometria non-euclidea. Sulla scorta degli interessi del padre Farkas (amico di Gauss) iniziò nel 1820 gli studi sul quinto postulato di Euclide, ma già nel 1823 anzichè tentarne una dimostrazione partì dal presupposto che per un punto esterno ad una retta data passino infinite parallele ad essa e cercò di trarne tutte le possibili conseguenze. Sviluppò così una geometria non-euclidea che chiamò " Scienza assoluta dello spazio ". Il manoscritto, finito nel 1829, venne pubblicato come appendice all'opera paterna nel 1832 con titolo Appendix scientiam spatii absolute veram exhibens . L'opera di Bolyai era stata sviluppata indipendentemente sia dal lavoro di N. I. Lobacevskij (pubblicato nel 1829), sia dalla convinzione a cui era giunto in precedenza Gauss circa la possibilità logica di una geometria non-euclidea coerente, mai resa di dominio pubblico.

69. Janos Bolyai Jest bowiem dramtem czlowieka gleboko zaangazowanego w rozwój nowych,rewolucyjnych idei. janos bolyai urodzil sie w 1802 roku w Kolozsvar. http://www.mat.uni.torun.pl/~cichy/Janos Bolyai.htm

Historia tego Wêgra jest szczególnie interesuj¹ca. Jest bowiem dramtem cz³owieka g³êboko zaanga¿owanego w rozwój nowych, rewolucyjnych idei. Janos Bolyai urodzi³ siê w 1802 roku w Kolozsvar. Ojciec jego Wolfgang, profesor matematyki, strawi³ znaczn¹ czêœæ ¿ycia nad dylematem niezale¿noœci pewnika Euklidesa od pozosta³ych aksjomatów geometrii, jednak¿e powa¿niejszych wyników na tym polu nie osi¹gn¹³. Dlatego przekonywa³ syna, by nie zajmowa³ siê tym problemem. Janos wszak¿e nie poszed³ za rad¹ ojca i ju¿ podczas swych studiów w Królewskiej Akademii In¿ynieryjnej w Wiedniu zacz¹³ poszukiwaæ w³aœciwego rozwi¹zania. Zachowane rysunki pochodz¹ce z tego okresu wskazuj¹, ¿e m³ody Bolyai znalaz³ w³aœciw¹ drogê. Kontynuuj¹c swe poszukiwania, ju¿ w 1825 roku doszed³ do podstawowych pojêæ i twierdzeñ geometrii nieeuklidesowej. Jednak¿e ich œcis³e dowody zabra³y mu dalsze szeœæ lat pracy. Opracowawszy w koñcu uzyskane wyniki, zamieœci³ jej w formie dodatku do ksi¹¿ki swego ojca, wydanej w 1832 roku. Wyk³ad owego dodatku, nosz¹cego tytu³ "Appendix scientiam spatii absolutu veram exhibens", odznacza³ siê skrajn¹ zwiêz³oœci¹ i schematycznoœci¹, ale ze wzglêdu na przemyœlenie ka¿dego s³owa i oznaczenia nale¿y to dzie³o do najpiêkniejszych w literaturze matematycznej. Mimo swej wagi, ukazanie siê pracy matematyka wêgierskiego nie wzbudzi³o wiêkszego zainteresowania, poza jedynym entuzjastycznym przyjêciem Gaussa. Bardziej jednak ni¿ brak zainteresowania zabola³o Bolyai'a oœwiadczenie Gaussa, jakoby ten posiada³ podobne wyniki. Odt¹d Bolyai bêdzie mia³ w podejrzeniu Niemca, przypuszczaj¹c, ¿e ten wykorzystuje jego idee. Silnie odbi³o siê tak¿e na psychice Wêgra jego niepowodzenie w premiowanym konkursie og³oszonym w Lipsku w 1837 roku. Bolyai nadsy³a œwietn¹ pracê, poprzedzaj¹c¹ konstrukcjê Hamiltona. Nie zyskuje ona jednak uznania w oczach jury. Pog³êbiaj¹ca siê deprezja osi¹ga u Bolyai'a swoje dno po ukazaniu siê w 1840 roku niemieckiego wydania pracy £obaczewskiego zatytu³owanej "Geometryczne rozwa¿ania w teorii prostych równoleg³ych". Bolyai dochodzi do wniosku, ¿e £obaczewski to nie istniej¹ca osoba, za któr¹ ukrywa siê Gauss. Od tej pory Wêgier nie opublikuje niczego wiêcej o matematyce, umrze piêæ lat przedtem, zanim jego idea uzyska powszechne uznanie.

Farkas Wolfgang Bolyai (Bolya 1775 - Marosvasarhely 1856) Mathématicien hongrois. Il enseigna les mathématiques, la physique et la chimie à Marosvasarhely toute sa vie. Contemporain de Gauss, il entretient avec lui une longue correspondance. Il s'intéresse aux fondements de la géométrie et plus particulièrement au cinquième postulat d'Euclide. Janos Bolyai (Kolozsvar 1802 - Marosvasarhely 1860) Son fils Janos (1802-1860), officier du génie, consacre ses loisirs à la construction d'une nouvelle géométrie en remplaçant le cinquième postulat d'Euclide par l'axiome suivant : 'Par tout point extérieur à une droite il passe une infinité de parallèles à cette droite'. Gauss approuve totalement ses recherches et signale qu'il connait déjà ces résultats depuis de nombreuses années : Lobatchevski était arrivé au même résultat que lui. Déçu de ne pas être le premier mathématicien à avoir trouvé cette nouvelle géométrie (géométrie non-euclidienne), Bolyai ne publie plus aucun résultat. A noter cependant que l'on appelle quelque fois la géométrie dite de Lobatchevski, la géométrie de Bolyai.

BOLYAI, Janos Matemático húngaro nasceu em Kolozsvár, Hungria (agora Cluj, Romênia), 15 de dezembro de 1802 faleceu em Marosvásárhely, Hungria (agora Târgu-Mures, Romênia), 17 de janeiro de 1860. Janos Bolyai era filho de um matemático que. durante sua juventude, havia sido um bom amigo de Gauss. O velho Bolyai havia tentado provar o axioma das paralelas de Euclides mas evidentemente fracassará. Com 15 anos, Bolyai ingressou na Escola de Engenharia de Viena e, com 20 anos, alistou-se. Além de seus dotes matemáticos. ainda possuía vários dos atributos românticos húngaros, tais como ser exímio violinista e excelente esgrimista. Conta-se que teria um dia duelado com 13 homens, um após o outro, que entre cada duelo tocava violino, e que te­ria derrotado a todos. Em 1825 ou 1826 desenvolvia uma linha de pensamento idêntica à que Lobachevski estava elaborando na Rússia. Em 1831, o velho Bolyai publicou um tratado de matemá­tica no qual incluiu um apêndice de 26 pági­nas, escrito por seu filho, e que valia várias vezes o resto da obra. Explicava a geometria não-euclidiana que Lobachevski, ainda des­conhecido por Bolyai, havia divulgado três anos antes. Gauss admirou o trabalho, mas não con­seguiu resistir à baixeza de afirmar que já o havia feito alguns anos antes (sem, todavia, publicá-lo, provavelmente porque, apesar de possuir a genialidade, faltava-lhe a coragem necessária para enfrentar as ásperas críticas que não teriam faltado se publicasse idéias tão revolucionárias). Bolyai, muito embaraçado, mas também muito orgulhoso, recusou-se a fazer qualquer trabalho adicional nesse sen­tido.
