Roberwal Category: ParallelfŸhrungen (Parallel guides) Item Number: Description: Vollkommene HebelparallelfŸhrung, Oberschalige Waage (Complete Parallel Lever Guide, Top-pan Scale) Biographical Information: Though Reuleaux used the name Roberwal, he was probably referring to Gilles Personne de Roberval (1602-1675). Roberval came from a poor French family, and received no formal schooling. At an early age Roberval left his family and traveled throughout the French countryside, learning mathematics from various classes given at different universities, and earning a living as a mathematics tutor. His travels eventually took him to Paris where he met and befriended members of the Mersenne circle (especially Claude Hardy, Claude Mydorge, ƒtienne Pascal and Blaise Pascal) in 1628. Four years later he was appointed professor of philosophy in the CollŽge de Maitre Gervais, and in 1634 he received the Ramus chair of mathematics in the CollŽge Royale (in 1655 he also received the Gassendi chair of mathematics). RobervalÕs involvement with the advancement of mathematics spanned several different disciplines. Not only did he promote the use of the geometry of infinitesimals, but he also wrote on finding areas, algebra, analytical geometry, and he developed methods for integration (computing the definite integral of sin x). But more importantly for the history of kinematics, Roberval was one of the first mathematicians to work on the composition of movements and methods of drawing a tangent to a curve, essentially founding kinematic geometry.

ADDENDA. No. 5. Cipher writing. At page 398, reference is made to a Cipher letter, engraved in " The Life," at page 180. It was written by the Marquis, as now appears, at Dublin, thc 29th of September, 1645. The author having made out the character, is able to supply the following Key, or alphabet. Curiously enough it is the document given at page 139, so that Carte must have obtained a deciphered copy as well. But the words, " the King of the assent," should be " the King of his assent." The words, " towards your Execllency" (in the 10th line) are not in the original. Also the words, " And my intention was ever to acquaint your honour herewith," should be " and mine intent was ever to acquaint you herewith." There is no signature to the original, but the written direction shows it was from the Earl of Glamorgan. We have now authentic proof of the construction and character of at least one Cipher method of writing adopted by the Marquis, eighteen years prior to the publication of the " Century." No. 53.

46. CONIC SECTION - LoveToKnow Article On CONIC SECTION claude mydorge (15851647), a French geometer and friend of Descartes, publisheda work De sectioni bus conicis in which he greatly simplified the cumbrous http://5.1911encyclopedia.org/C/CO/CONIC_SECTION.htm

CONIC SECTION CONIC SECTION The definitions given above reflect the intimate association of these curves, but it frequently happens that a particular conic is defined by some special property (as the ellipse, which is the locus of a point such that the sum of its distances from two~ fixed points is constant); such definitions and other special properties are treated in the articles ELLIPSE, HYPERBOLA and PARABOLA. In this article we shall consider the historical development of the geometry of conics, and refer the reader to the article GEOMETRY: Analytical and Projective, for the special methods of investigation. But the greatest Greek writer on the conic sections was Apollonius of Perga, and it is to his Conic Sections that we are indebted for a review of the early history of this subject. Of the eight books which made up his original treatise, only seven are certainly known, the first fouI in the original Greek, the next three are found in Arabic translations, and the eighth was restored by Edmund Halley in 1710 from certain introductory lemmas of Pappus. The first four books, of which the first three are dedicated to Eudemus, a pupil of Aristotle and author of the original Eudemian Summary, contain little that is original, and are principally based on the earlier works of Menaechmus, Aristaeus (probably a senior contemporary of Euclid, flourishing about a century later than Menaechmus),Euclid and Archimedes. The remaining books are strikingly original and are to~be regarded as embracing Apolloniuss own researches.

He was also a friend of Gassendi and Mydorge . Hardy introduced Mydorge to Descartes Hardy, in his capacity as a lawyer, worked for the Parliament in Paris from 1625. A year later he was certainly attached to the court of justice in Paris as a counsellor. In 1630 he published Examen and in 1638 Refutation . These works dealt with the problem of the duplication of the cube and Hardy pointed out a fallacy which had arisen regarding this problem. Hardy took part in many of the mathematical discussions and arguments of the time but his greatest contribution was his knowledge of Arabic and other languages which enabled him to make important Latin translations of Euclid 's Data and other books. Despite the fact that he introduced Mydorge to Descartes , Hardy supported Descartes when the two had a dispute over Fermat 's method of maxima and minima, a forerunner to the calculus.
