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.

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.

János Bolyai From Wikipedia, the free encyclopedia. (Redirected from Janos Bolyai 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 Bolyai discovered that Lobachevsky had published a similar piece of work in In addition to his work in geometry, Bolyai developed a rigorous geometric concept of complex numbers as ordered pairs of real numbers . Although he never published more than the 24 pages of the Appendix, he left more than 20000 pages of manuscript of mathematical work when he died. These are now in the Bolyai-Teleki library in Targu-Mures , Romania.

For Age: 4 years and up LeapPad by LeapFrog At Amazon on 4-15-2003. More Info This talking book comes with an interactive ''magic pen'' that works like a hand-held computer mouse pointer. Children can opt to turn the paper pages and listen to the story read with different voices for each character. Or they can interrupt the read-aloud session to play with the magic pen (permanently attached with a wire). They can point the pen tip to any word on a page and hear it pronounced, or touch a picture and hear a sound effect (such as ''Strike one!'' for the baseball bat). Very similar to the popular Living Books computer games, this 10-by-11-inch book is more portable than a home computer. Stories in this set include Lil's Loose Tooth, Richard Scarry's Best Word Book Ever, and Winnie the Pooh in A Sweet Good Morning. The set also includes a paper piano keyboard and map and human anatomy games. Gail Hudson Batteries: 4 AA batteries required. How to Prepare for the SAT II: Math Level IC by James J.
