Britannica CD Index Articles Dictionary Help (b. June 28, 1875, Beauvais, Fr.d. July 26, 1941, Paris), French mathematician whose generalization of the Riemann integral revolutionized the field of integration. He was (lecture master) at the University of Rennes until 1906, when he went to Poitiers, first as (assistant lecturer) of the faculty of sciences and later as professor. About six years later he went to Paris as One of the greatest mathematicians of his day, Lebesgue's pavement theorem is an important contribution to topology, and he did some work on Fourier series and potential theory (the theory of functions describing a conservative energy field). However, his main work was in integration. Lebesgue integral is one of the great achievements of modern real analysis. With Lebesgue integration, any bounded, summable function is the derivative of its indefinite integral, except perhaps for an ensemble of points with zero measure. Lebesgue integration was also instrumental in greatly expanding the scope of Fourier analysis. In addition to about 50 papers, Lebesgue wrote two major books

Quantum Physics Pampered Chef Paintball Guns Cell Phone Reviews ... Science Articles Henri Lebesgue Online Encyclopedia ) was a mathematician most famous for his theory of integration , which he developed in Lebesgue's theory of integration This is a non-technical treatment from a historical point of view; see the article Lebesgue integration for a technical treatment from a mathematical point of view. Integration is a mathematical operation that corresponds to the informal idea of finding the area under the graph of a mathematical function . The first theory of integration was developed by Archimedes in the third century BC with his method of quadratures, but this could be applied only in limited circumstances with a high degree of geometric symmetry. In the seventeenth century Isaac Newton and Gottfried Wilhelm Leibniz independently discovered the idea that integration was a sort of opposite of differentiation (which they had just invented), which allowed mathematicians to calculate a broad class of integrals for the first time. However, unlike Archimedes' method, which was based on Euclidean geometry , Newton's and Leibniz's integral calculus did not have a rigorous foundation.

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.
