Francois Viyet

Francois Viyet - French mathematician, first base algebra as the knowledge of the transformation of expressions of figure out equations in world(a) form, creator of of import calculation. Viyet letters came to uphold not but unknown, but selective information great(p)ness. Thus he was able to salute into science prypuschennyao great possibility of the algebraic manipulations of characters that introduce the invention of a numerical formula. That he do a fateful contribution to the institution of alpha algebra, the entire development of mathematics Renaissance and coat the way for the coming into move of the results Fermat, Descartes, Nyutona.\nViyet Francois was born in 1540 in grey France in a small townsfolk Fantene Le Comte nation of Poitou, located at 60 km from La Rochelle, who was at that time a warmhold of the French Protestant Huguenots. (Huguenots, followers of Calvinism, one of the important trends of the Reformation of the Church.) roughly of his lif e he lived near the chief(prenominal) leaders of the movement, although he remained a Catholic. possibly Religious disagree scientist bothered.\nHis father was a scientist prosecutor. Traditionally, the son chosen professiyu father and became a attorney after graduating from university in Poitou. In 1560, twenty attorney began his career in his hometown. As a lawyer Viyet utilize in human race authority and respect. entirely three years later entered the serving of the well-known Huguenot family which Partenite. He became privy(p)ary of the homeowner and teacher his girl Catherine twelve. This study raise interest in the young lawyer Da mathematics.\nWhen a student has large and married, Viyet not disunite from her family and moved with him to Paris, where it was easier to drive about the achievements of the leading mathematicians of Europe. With some scientists Viyet met in person. He rundle with a illustrious professor at the Sorbonne Ramus, with the largest I talian mathematician Rafael Bompelli waged a friendly correspondence. In 1671 rots Viyet passed the civil service, nice a counsellor of parliament in Brittany. Familiarity with atomic number 1 Navarrese, the approaching king of France enthalpy IV, helped Viyetu take a prominent court positions - a mystic councilor - first on a lower floor King enthalpy III and later under Henry IV.\nHe was noteworthy during the Franco - Spanish war. Spanish Inquisitors have invented a very exhausting encipher, which consisted of about 600 characters and invariably changed and supplemented. This bet is strong and militant at the time Spain could vilnolystuvatysya opponents of French king, even in France itself, and this correspondence has remained unsolved. afterwards futile attempts to point out the key to the cipher King zvernkvsya to Viyeta. They opine that Viyet within twain weeks along the days and nights spent at work, yet make up the key to the cipher. hence suddenly the Span iards France was the fetching one meshing after another. later on the Spaniards learned that the code for the French no longer secret and that its perpetrator decipherment - Viyet. Convinced of the impossibleness of cryptography mode to solve the slew they accused of France to the pope and the Inquisition in leprosy Devil and Viyet was supercharged in federation with the devil and sentenced to be burned in the flames. Fortunately for science, he has not been issued by the Inquisition.
