  • 1. Bolyai János valóban igen fiatalon megismerhette a számelmélet alapvetõ kérdéseit. Apja könyvtárában már 1804-ben ott volt Gaussnak Bolyai Farkas szerint "halhatatlan" Disquisitiones arithmeticae "... felnõtt tanítványaimmal együtt nyilvánosan igen dicséretesen vizsgázott deákul..." "Fiamnak szándéka volt, hogy a Te polygon-elméletedet németül, a kisebb kaliberû elméknek valamivel könnyebben hozzáférhetõ módon adja ki..."
    "Már kisgyermek koromban feltettem magamnak a kérdést, hogy végtelen sok prímszám létezik­e?"

    Érthetetlen, hogy Gauss miért nem értesítette Bolyai Farkast 1832­ben elsõ elõadásáról is, s arról a késõbbiekben sem írt. Gauss 1832. március 6­ai levelére Bolyai Farkas 1835. április 20­án válaszolt s az "imagináriusokról szóló közlést" akkor köszönte meg. Közben hírt kapott Gauss elsõ elõadásáról is, mert már a következõ, október 4­ei levelében ezt írta:

    "Utinam Gauss superstes esset!"
    l. Lajos, Alexits Weszely Tibor Nézzük meg rendre, mindvégig a kéziratokat faggatva, hogy miképpen vélekedett Bolyai János a számelméletrõl, annak nagy alakjáról, Gaussról, remekmûvérõl, a Disquisitiones arithmeticae-rõl, majd pedig vizsgáljuk meg a hagyatékban eddig "rejtõzõ" néhány számelméleti eredményét. Erre a mûvére Gauss is büszke volt. Egy 1808. szeptember 2-án Bolyai Farkashoz írt levelében úgy nyilatkozik, hogy a Disquisitiones arithmeticae-t csak hat matematikus értette meg egész Európában. Ugyanitt a számelméletrõl szólva azt mondja: "Figyelemre méltó, hogy bárkit, aki komolyan foglalkozik ezzel a tudománnyal, igaz szenvedély kerít hatalmába."
    Bolyai János legtöbbet a prímszámokkal veszõdött. "Az egész számtan sõt az egész tan mezején - vallja - alig van szebb és érdekesebb... s a legnagyobb nyiászok (matematikusok - K E.) figyelme és eleje óta elfoglalt tárgy, mint a fõszámok (prímszámok - K. E.) oly mély homályban rejlõ titka".

The sculpture represents the pseudo-sphere on which the non-euclidian Bolyai-Lobachevsky geometry is applied. post a comment Subject: Tirgu Mures : Sculpture of the Bolyai's Date: This picture is me in front of the sculpture representing the two world famous mathematicians, the Bolyai's, Bolyai Janos and Bolyai Farkas, who lived and created in Tirgu Mures. Bolyai Janos was one of the founders of the Bolyai-Lobachevsky geometry, a revolutionary non-euclidian geometry. 1 comment post a comment Subject: Tirgu Mures : Teleki library Date: The Teleki library was founded in 1797-1799 and houses a large collection of rare and ancient books in original. The founder was Teleki Samuel, a well known politician at his time. He was so concerned about his collection of rare books, that he ordered through his will, that no lighting or heating shall be used inside the library. Fortunately with the invention of electricity, that was no longer an inconvenience, since light bulbs and electric heaters are no threat to the books. post a comment Subject: Tirgu Mures : Pseudo sphere Date: A close-up on the pseudo-sphere. On the chamfered corner there is the famous quote from Bolyai Janos: "Out of nothing I have created a strange new universe" (a reference to the creation of a non-euclidean geometry).

    Janos Bolyai
    Janos Bolyai is most noted for having authored a complete treatise on a complete system on non-Euclidean geometry. Born on December 15, 1802 in present-day Romania then Hungary ). By the tender age of 13, Bolyai had developed a mastership of calculus and other sorts of analytical mathematics and mechanics. Mainly, Janos was taught by his father, Farkas Bolyai , who gave his son unparalleled instruction. Meanwhile, Janos became an equally talented violinist who performed in Vienna. Thus, Janos embarked on a study of engineering at the Royal Engineering College in Vienna from 1818 to 1822. As soon as Janos completed his studies, he joined the then Austro-Hungarian Imperial Army as an engineer and he was known as the best swordsman and dancer in the army. Notably, Janos adhered to a puritanical style of life and he did not smoke and did not drink. His genius lead him to learn nine languages including Tibetan. Janos Bolyai's treatise was an immense milestone in non-Euclidean development. From 1820 to 1823, Janos authored a treatise on a full non-Euclidean system. Sadly, Janos discovered that his ideas had been anticipated by

    Hungarian mathematician who was the son of Farkas Bolyai . When Bolyai began puzzling over Euclid's fifth postulate his father wrote him "For God's Sake, I beseech you, give it up. Fear it no less than sensual passions because it, too, may take all your time, deprive you of your health, peace of mind, and happiness in life" (Boyer 1968, p. 587). Janos did not heed his father, however, and his work, which paralleled that of Lobachevsky , was published by his father. However, Bolyai's lack of recognition and the publishing of Lobachevsky's work led him to publish nothing more. Bolyai (Farkas) Lobachevsky

    Bolyai published his findings in 1832 in an appendix to a mathematical work of his father. Later it was learned that Lobachevsky had published similar findings as early as 1829-1830, but, because of language barriers and the slowness with which information of new discoveries traveled in those days, Lobachevsky's work did not become known in western Europe for some years.. There seems little point in discussing here the intricate, and probably unfounded theories explaining how various of these men might have obtained and appropriated information of the findings of some other. There was considerable suspicion and incrimination of plagiarism at the time.
    Nicolai Ivanocitich Lobachevsky spent the greater part of his life at the University of Kasan first as a student, later as a professor of mathematics, and finally as rector. His earliest paper on non-Euclidean geometry was published in 1829 and 1830 in the Kasan Bullentin , two to three years before Boyai's work appeared in print. This memoir attracted only slight attention in Russia, and, because it was written in Russian, practically no attention elsewhere. Lobachevsky followed this initial effort with other presentations. For example, in the hope of reaching a wider group of readers, he published, in 1840,a little book

    English Janos Bolyai Biography Janos Bolyai (December 15, 1802 - January 27, 1860) was born in Kolozsvar, Transylvania, at that time a Hungarian Grand Duchy ruled by the Hapsburgs, and died in Marosvasarhely, Transylvania. Janos Bolyai, son of Farkas Bolyai, the famous professor of mathematics, physics and chemistry at the Reformed College in Marosvasarhely, as a teenager set himself to resolve the 2000 year old geometry problem, intensively researched also by his father: T o prove Euclid's fifth, the so called parallel postulate from Euclid's others. The fifth postulate requires that given a line in the plane and a point outside of it, there exists exactly one line through the point that is parallel to the line. After he had recognized the impossibility of this task, he developed absolute geometry that is independent of the fifth postulate and also hyperbolic geometry where this postulate is negated in such a way that infinitely many parallels are assumed to exist through the given point to the given line.
