History
nikolai lobachevsky (17921856) was a Russian mathematician, and the firstto publish a complete book about this imaginary geometry in 1829.

Extractions: Proving a Postulate Girolamo Saccheri (1667-1733) was a Jesuit priest from Italy. First to try proving the parallel postulate using a proof by contradiction, h e uncovered two new types of geometry. Carl Friedrich Gauss (1777-1855) was a German mathematician who tried to prove the fifth postulate. He assumed that multiple parallel lines existed and thought that other types of geometry might exist. He developed hyperbolic geometry, but never went public for fear of controversy. Janos Bolyai (1802-1860) was a Hungarian Army officer and a mathematician. He assumed that there were more than one parallel line and published his findings in 1832. He wrote, "out of nothing I have created a strange new world." Nikolai Lobachevsky (1792-1856) was a Russian mathematician, and the first to publish a complete book about this "imaginary geometry" in 1829. This year is considered the birth of Non-Euclidean geometry. Bernhard Riemann (1826-1866) was a German mathematician. He wrote his doctoral dissertation under the supervision of Gauss. His inaugural lecture in 1854 reconfigured the entire concept of geometry. His work was in spherical geometry.

Extractions: 1829, in dem Jahr, als Nikolai Ivanovich Lobachevsky seine Theorie einer nicht-euklidischen Geometrie veröffentlichte, war die einst enge Verbindung zwischen Architektur und dem Rand des Wissens bereits nahezu aufgelöst. Fast gleichzeitig veröffentlichte Victor Hugo 1830 "Notre Dame de Paris", eine Erzählung, die ein architektonisches Werk in Buchform ist. 1832 gab Hugo die zweite und endgültige Fassung von "Notre Dame de Paris" heraus, der er ein Kapitel mit der Überschrift "Ceci Tuera Cela" (Dies wird jenes töten) hinzugefügt hatte. Das ganze Buch, besonders aber dieses Kapitel, setzt sich ausführlich mit der Erkenntnis auseinander, daß das Buch die Architektur getötet hat. Platon erwartete nicht, daß das menschliche Wissen statisch sein würde, auch wenn er sich vorstellte, daß die ideale Welt dies wäre. Zu Beginn des Timaios macht er deutlich, daß die im Folgenden ausgeführte Theorie nur eine "wahrscheinliche Erzählung" sei. Sie sei zwar so gut, wie man sie zu hören erwartet, aber bleibe nichtsdestoweniger eine Erzählung, weil Menschen niemals die Wirklichkeit vollständig erkennen können. Diese Annahme impliziert, daß dann, wenn sich das menschliche Wissen verändert, so bruchstückhaft und fehlerhaft es auch sein mag, auch die damit zusammenhängende Architektur sich verändern müsse: eine langsame Kunst, die dem langsamen Wachstum der menschlichen Erkenntnis folgt.

So here's another non-classical review from me :-P For those of you who don't know Tom Lehrer... he's the most brilliant creative genius that America has produced in almost 200 years, endowed with the most glorious baritone voice to be heard on an American stage, endowed with twelve incredibly agile fingers, who had a long and varied career in the field of entertainment, with 9 years starting at Harvard University... (OK, that was a joke blatantly ripped off the first track of this CD, so sue me! :-P) Alright, so here are the tracks on this CD. These are the songs Lehrer plays in his concert. Personally, although some of the stuff here is pretty good, I still prefer the first CD, An Evening Wasted with Tom Lehrer . It could be because of the audience response... the audience in this CD obviously had heard most of the songs before, so there weren't enough laughs to make it funny. Introduction where Tom Lehrer introduces himself humbly in the third person. No songs on this track, but it's extremely funny.

Extractions: Volume XXI, Number 2, April 1997 In the Elements , Euclid derived all of geometry (and other areas of mathematics) from a set of just ten statements which he assumed to be true. These statements were in turn divided into two groups: the five common notions, which were applicable to all areas of mathematics, and the five postulates, which applied specifically to geometry. Unfortunately, while most of the common notions and postulates were simple, straightforward sentences, the fifth postulate, also known as the parallel postulate, looked a little worse: If a line segment falls on two other line segments in such a way that the interior angles on the same side are less than two right angles, then the two line segments, if extended indefinitely, meet on that side on which the angles are less than the two right angles. The unpleasant appearance of this statement is due in part to the fact that mathematicians of the past were less comfortable about dealing with infinity, so Euclid was trying to word things in terms of a finite figure. A simpler, equivalent statement was written by John Playfair in 1795 although it does require us to imagine the infinite extent of the lines described:

Another of the great mathematicians who seems to have preceeded Bolyai in his work is Carl Fredrich Gauss . He seems to have done some work in the area dating from 1792, but never published it. The first to publish a complete account of non-euclidean geometry was Lobachevsky in . It was first published in Russian and was not widely read. In he published a treatise in German.

Extractions: Ivan Delianov. Lithograph by Peter Borel from a photograph by Steinberg. 1860s T The opening of the Public Library which coincided with what Pushkin called the time of "glory and delight" was recorded in all the St Petersburg newspapers. The poet and critic Piotr Pletnev wrote that all men and women whose "Russian hearts beat stronger on hearing the word Motherland" had perceived the event as "a glorious occurrence" important for the future of the country. The library remained a popular topic in subsequent years too. The papers described it as "a tmly national repository" and noted that any reader "had free entry to it, whatever title or rank he may have held." The Olenin years, in the course of which over 15,000 library cards were issued and some 100,000 volumes given out to readers, also saw the first attempts to analyse reading patterns, the range of subjects which interested users of the library and the demand for works by particular authors (Lomonosov, Karamzin, Derzhavin, Krylov, Zhukovsky, Gnedich, Batiushkov, and others). The same period was marked too by the inception of a reference and bibliographical service within the library as members of staff began to select literature systematically in response to readers' requests (books, for example, on the history of the 1812 War, Suvorov's campaigns in Italy and Switzerland, or public education in Russia). At the request of Stroganov and Olenin, the book-dealer Vastly Sopikov, a member of the merchant class, was taken into state service at the library. Sopikov had become famous for his knowledge in the field of Russian bibliography and the book trade. He was entmsted with managing the Russian stocks and the library saw to the publication of his major work An Essay in Russian Bibliography which the author per-spicaciously believed "will be a classic not only in Russia but also in foreign parts". Sopikov's work contained "an accurate and thorough description" of books published in Russia from the introduction of printing to the beginning of the nineteenth century and still remains a valuable handbook for librarians and bibliographers today.
Bigchalk: World Book Online
geometry is sometimes called Lobachevskian geometry, because it was developedinthe early 1800'sby the Russian mathematician nikolai lobachevsky.
http://worldbook.bigchalk.com/221160.htm

Extractions: Geometry, jee AHM uh tree, is a branch of mathematics. Geometry involves studying the shape, size, and position of geometric figures. These figures include plane (flat) figures, such as circles, triangles, and rectangles, and solid (three-dimensional) figures, such as cubes, cones, and spheres. The name geometry comes from two Greek words meaning earth and to measure. The earliest uses of geometry included measuring lengths and areas of land. Most scholars believe that the ancient Egyptians were the first people to make extensive use of geometry. Geometry is important for many reasons. The world is full of geometric shapes. For example, snowflakes are shaped like hexagons (six-sided figures), and earthworms are shaped like cylinders. Houses and buildings have rectangular walls, and many bridges have triangular supports. Because geometric shapes are all around us, we can better understand and appreciate our world by knowing something about geometry. Geometry also has practical applications in many fields. For example, architects and carpenters must understand the properties of geometric objects to construct stable and attractive buildings. Navigators of airplanes, ships, and spacecraft rely on geometric ideas to chart and follow the correct course. Designers, engineers, metalworkers, and photographers also use geometric principles in their jobs. Geometry as a logical system
