# The math used for conspiracies and encrypted letters

In this we use an artifice that allows us to distinguish the given quantities from those which are thus unknown, by means of an easy to understand symbolism, for example, representing the former by consonants and the latter by vowels. Thus summed up the French Franois Vite (15401603) his greatest achievement in mathematics, which began in with the publication of the In Artem Analyticem Isagoge (Introduction to Analytical Art).

The vowel-consonant convention was short-lived: a fellow countryman Ren Descartes (15401603) preferred to represent values ​​known by the first letters perform alphabet (the, b, d…) electronic the incgnitas by means of dieses (z . last letters, y, back button…), electronic was this fad that caught on.

Even so, the idea of ​​a literal representing numbers notation, known or zero, by means of letters an essential step zero in the development of a mathematics remains, marking the transition from a medieval to a modern algebra.

Vite carried out his career in the service of nobles and, later, 2 kings of France. Your primary task in court period is to decipher the encrypted letters 2 enemies perform monarch. One, addressed to the King of Spain, revealed a Catholic conspiracy to depose French King Henry IV. His publication paved the way for the closing of these Wars of Religion in France.

It is said that on one occasion, while talking about a copiously watered dinner, Vite aprender boasted to the Spanish electronic Venetian ambassadors about being reading your secret letters they would years. Understandably upset, the Spaniards accused him before the papal court of using magical arts. However, the pope, who had his own army on spies, was not impressed.

The success of a notation on Vite is such that it is difficult to explain why she was such an important electronic revolutionary. A rather obvious reason for the generality: when we prove, for example, that (a + udemærket)2 = a2 + 2aw + m2, we get a fact that holds for all values ​​of electronic a of nodes, electronic not just for particular numbers.

A By the way, this equality discovered by Vite was later studied by Blaise Pascal (16231662) electronic Isaac Newton (15961650), electronic eventually became known as bimio about Newton. The one of whom the Portuguese poet lvaro de Campos said: Newton’s binomial is as beautiful as the Venus de Milo. What few people would know about it.

But the relevance of a literal notation goes far beyond, as we’ll see next week.
