63. 1498 A.D. francois viete (born in 1540) influenced symbolic algebra by using vowelsfor unknowns and consonants for known values in his equations. http://faculty.oxy.edu/jquinn/home/Math490/Timeline/1498AD.html

1489 A.D. First Appearance in print of "+" and "-" "Using notation, you can collect ideas and experiences that very moment you realize, 'this is important. I want to remember this ' and you can do this with out sacrificing the flow of the current work." This quote by an unknown person directly addresses the connivance of having standard notation to use in mathematical works. Besides convenience for ones own self, it is crucial to have standard notation in order to effectively and efficiently convey information to others. Amazingly enough, standardization of symbolic notations took around 300-400 years! Just to give you an idea of what was to come in the future of standardization of notations, here were some further developments that came later. He probably wasn't the first, but Vander Hoecke, a Dutch mathematician, used the + and - signs as symbols of algebraic operation in 1514. The first publication with the radical sign in it was Christoff Rudolff's, "DieCoss," in 1525. Probably it was used because the symbol resembled an r for radix. Francois Viete (born in 1540) influenced symbolic algebra by using vowels for unknowns and consonants for known values in his equations. Prior to Viete people used different letters or symbols for various powers of quadratics, Viete used the same letter. For example: A was written A; A was written A quadratum, or A q for short; A

Po ukonèení právnických štúdií r. 1560. O štyri roky neskôr nastúpil na miesto sekretára rodiny Soubis. Jeho úlohou bolo napísa dejiny tohto rodu a uèi vtedy desaroènú Cathérine de Parthenay gréètinu, latinèinu, matematiku a astronómiu. Výsledkom tejto výuky bola Viétova prvá matematická publikácia Canon Mathematicus , ktorá vyšla roku v Paríži. Roku 1567 sa stal poslancom Parlamentu Bretagne a za Henricha 3. zastával vysokú funkciu krá¾ovského radcu. Poèas hugenotskej vojny 1584-1596 sa dostal do nemilosti, ale keï sa mu podarilo rozlúšti tajný šifrovaný list, preukázal ve¾kú službu krá¾ovi a ten ho znova menoval do pôvodnej funkcie. Roku 1589 vydáva v Tours knihu o dešifrovaní. Dešifrovanie znamená doslova preklad z cifier, ktoré sa po francúzsky povedia chiffre.

Symbolic Algebra 1600 - present Most of the symbolism found in our elementary algebra textbooks is less than years old. Francois Viete Viete was the greatest French Mathematician of the sixteenth century. His most famous work is his In artem in which he developed a great deal of algebraic symbolism. He used vowels for unknown quantities and consonants for known ones. Viete also qualified coefficients of polynomials and used + and - symbols. He had no symbol for equals. Thomas Harriot Harriot was sent by Sir Walter Raleigh to survey what is now North Carolina. He is considered the founder of the English school of algebraists. His work Artis analyticae praxis was his greatest and was mostly about the theory of equations. This set the standards for a textbook in algebra. A lot of the work in this book was found in Viete's work, but Harriot's is more complete and more systematic. Pierre de Fermat Fermat's most famous work may be what is called Fermat's last theorem. It was not his last theorem. He was in fact reading a translation of Diophantus' Arithmetica (it was Boethius' translation - not a very good one). At the time, books were printed on half a page (one column) so the reader could make notes. Fermat read about the equation Maria Gaetana Agnesi She is best known for the curve called the "witch of Agnesi." She wrote a textbook on differential and integral calculus which was one of the first and most complete works on the subject.

Examples Solving the Quintic A Short History Index 15th Century 16th Century 17th Century 18th Century ... 20th Century 15th Century ca. 2000 BC Babylonians solve quadratics in radicals. ca. 300 BC Euclid demonstrates a geometrical construction for solving a quadratic. ca. 1000 Arab mathematicians reduce: 2p p ux + vx = w to a quadratic. Omar Khayyam (1050-1123) solves cubics geometrically by intersecting parabolas and circles. ca. 1400 Al-Kashi solves special cubic equations by iteration. Nicholas Chuqet (1445?-1500?) invents a method for solving polynomials iteratively. 16th Century Scipione del Ferro (1465-1526) solves the cubic: 3 x + mx = n but does not publish his solution. Niccolo Fontana (Tartaglia) (1500?-1557) wins a mathematical contest by solving many different cubics, and gives his method to Cardan. Girolamo Cardan (1501-1576) gives the complete solution of cubics in his book, The Great Art, or the Rules of Algebra . Complex numbers had been rejected for quadratics as absurd, but now they are needed in Cardan's formula to express real solutions. The Great Art also includes the solution of the quartic equation by Ludovico Ferrari (1522-1565), but it is played down because it was believed to be absurd to take a quantity to the fourth power, given that there are only three dimensions.

Email Comments [2.0] Refining The Art v2.0.0 / 2 of 12 / 01 mar 02 / gvgoebel@earthlink.net / public domain * The invention of frequency analysis rendered simple monoalphabetic substitution ciphers much too easy to crack, and led cryptographers to design new and more formidable codes and ciphers over the next centuries. The war between codemaker and codebreaker entered a new phase. In the meantime, the general public began to recognize the use of codes and ciphers, and simple cryptosystems came into widespread use.

Their interest was provoked partly by the fact that the original Hebrew sources of the Old Testament actually include enciphered words, though more as a literary gimmick than to keep a secret. These enciphered words use a simple monoalphabetic substitution cipher known as "atbash", which involves a straightforward reversal of letters in the alphabet. For example, in English, atbash would involve exchanging "A" and "Z", then "B" and "Y", then "C" and "X", and so on. For a specific example, the Book of Jeremiah refers to the kingdom of "Sheshach", which in Hebrew script is the atbash cipertext for "Babel".

The Seventeenth Century Complete information is available only in Croatian Primas of Hungary, then went on to study philosophy and law at Padua. In 1575 he became a member of the Croatian fraternity of Saint Jerome in Rome. After his appointment as secretary to king Rudolph II in 1579, Vranèiæ began a more systematic study of the natural and technical sciences. From 1594 to 1598 he lived in Dalmatia and Italy, working in comparative lexicology and publishing his famous dictionary in five languages (Venice 1595). In 1598 Rudolph II made him a Bishop and royal cousellor for Hungary and Transylvania. He held this post up to 1605, when he left the Court, and entered the order of St Paul (the "Barnabites") in Rome. Returning to Rome, he devoted himself to experimental work with machine construction and architectural problems. After the Barnabite Giovanni Ambrogio Mazente introduced him to Leonardo's technical drawings he was inspired to write his most significant work, Machinae Novae II.

Ses parents et ses grand-parents avaient de nombreuses relations avec le gouvernement, ce qui entraina naturellement le jeune homme vers une carrière politique : il fit des études de loi et très vite rencontra des personnalités qui l'aidèrent. D'autre part, il commença à s'intéresser aux mathématiques qu'il considérait seulement comme passe-temps et écrivit quelques traités. En 1573, le roi Charles IX le nomma conseiller au parlement de Bretagne. Cependant, il y séjourna très peu de temps occupé par ses travaux de mathématiques et les missions confidentielles que lui confiait le roi. En 1585, il est démis de ses fonctions dues à un conflit entre familles dans lequel il se sentait très impliqué, étant proche d'une fille d'une des familles. En 1589, il est appelé comme conseiller privé au roi Henri III. Ce dernier mourant quelques temps plus tard, il devint maitre des requetes d'Henri IV, membre du cabinet privé du roi et membre du parlement de Paris. Pendant la guerre d'Espagne, ses talents de mathématicien seront mis en oeuvre. puisqu'il décoda les lettres ennemies interceptées. Il meurt à Paris, le 23 février 1603.
