János Bolyai December 15 January 27 ) was a Hungarian mathematician Bolyai was born in Kolozsvar (today Cluj-Napoca in Romania Transylvania , at that time part of the Austro-Hungarian Empire . When he was 13, he had mastered the calculus and other forms of analytical mechanics , his father Farkas Bolyai giving him instructions. He studied at the Royal Engineering College in Vienna from to . Between and he prepared a treatise on a complete system of non-Euclidean geometry . Bolyai's work was published in as an Appendix to an essay by his father. Gauss , on reading the Appendix, wrote to a friend saying "I regard this young geometer Bolyai as a genius of the first order". In

Nicolai Ivanovich Lobachevsky Lobachevsky published the first account of non-euclidean geometry. He derived his trigonometry formulas from the study horocycles and the horoshpere, rediscovering Watcher's theorem that the geometry of horocycles on the horosphere is the same as lines in the euclidean plane. Lobachevsky established the independence of Euclid's fifth postulate by pointing out that the geometry is entirely based on his formulae for a triangle which leads to the familar formulae for spherical triangles when sides a b c are replaced by ia ib ic . So any inconsistancy in the geometry would imply an inconsistancy in the spherical geometry which is part of euclidean geometry. Bolyai Janos ...a new universe from nothing. J Bolyai was the founder of Absolute Geometry that branch of geometry consisting of those propositions independent of the fifth postulate (and therefore appiciable to euclidean and hyperbolic geometry). Bolyai and Lobachevsky discovered non-Euclidean geometry simultaneously. Bolyai became interested in the theory of parallel lines under the influence of his father Bolyai Farkas . F Bolyai himself devoted considerable energy toward a proof the parallel postulate without success and tried to dissuade his son from such a hopeless endevor: I entreat you, leave the doctrine of parallel lines alone; you should fear it like a sensual passion; it will deprive you of health, leisure and peace it will destroy all joy in your life.

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 Gauss . Discouraged and dismayed, Bolyai did not publish his work. His father later published it as an appendix to one of his works. Gauss, however, regarded Janos with the greatest respect calling him a "genius of the first order". Importantly, Janos worked to disprove

: home : index-site :: About University From the point of view of its organization, the Babes-Bolyai University reached the largest dimensions ever in its history after 1993. Our university comes with one of the most complex and diversified study offers for Romanians and foreigners; it has 40.000 students, grouped in 19 faculties able to choose among over 100 specialization and provides a network of colleges in 18 towns in the area. ::: Learning from a University History I t has been almost four centuries since the beginnings of the university of Cluj. The first project to set up a higher education institution in Cluj was recorded in 1565 when the Diet which met in Cluj, together with prince Ioan Sigismund, decided to found a Calvinist college. Unfortunately, historical circumstances were against this project. H owever, the decree of May 12 1581 allowed Istvan Bathory to set up an academic college, organized and run by Jesuits. They chose the Italian scholar Antonio Possevino as head of the institution. It had three colleges: Theology, Philosophy and Law. Young people receiving degrees of bacallaureate, doctor and magister
