Pierre de Fermat Pierre de Fermat ble født 17. august 1601 og døde 12. januar 1665. Denne franske matematikeren gjorde viktige oppdagelser innen analytisk geometri og tallteori, og arbeidet også med sannsynlighetsregning og optikk. For Fermat, som var jurist i Toulouse og embedsmann, var matematikk bare en hobby. I 1636 presenterte Fermat et system innenfor analytisk geometri liknende til det som Rene Descartes skulle foreslå ett år senere. Fermat's arbeid, som var basert på et forsøk på å gjenskape arbeidet til den greske matematikeren Apollonios fra Perga, bruke algebraen til Francois Vitete. Et liknende forsøk på å gjenskape et gammelt arbeid, førte til metoder som liknet på differentialregningen og integrasjon, for å finne topp- ogg bunnpunkter på kurver og arealet omgitt av kurver. Fermat's største arbeid var innefor tallteorien, og han var spesielt interesert i egenskapene til primtall. Fermat samarbeidet med Blaise Pascal om sannsynlighetsregningen. Fermat publiserte nesten ingenting i løpet av livet sitt, vanligvis kunngjorde han sine oppdagelser i brev til venner eller så bare noterte han resultatet i margene på bøkene sine. Hans arbeid ble nesten helt glemt fram til midten av 1800-tallet. Fermattall Et tall av formen F n n + 1 der n er et naturlig tall. Hvis F

Pierre de Fermat French Mathematician 8-17-1601 to 12-12-1665 Pierre Fermat's father was a wealthy leather merchant and second consul of Beaumont- de- Lomagne. He was probably educated in his early years at the local Franciscan monastery. He attended the University of Toulouse before moving to Bordeau in the second half of the 1620s. In Bordeau he began his first serious mathematical researches and in 1629 he had completed his restoration of Apollonius's "Plane Loci." In Bordeau he was in contact with Beaugrand and produced important work on maxima and minima. From Bordeau Fermat went to Orléans where he studied law at the University. He received a degree in civil law and he purchased the offices of councillor at the parliament in Toulouse. Fermat's meteoric rise through the government is evidenced by his multiple appointments between 1631 and 1653. News of his death due to the plague of the 1650s was exaggerated: I informed you earlier of the death of Fermat. He is alive, and we no longer fear for his health, even though we had counted him among the dead a short time ago. The following report, made to Colbert the leading figure in France at the time, has a ring of truth:-

Pierre de Fermat Pierre de Fermat took the ideas of Descartes and expanded upon them to give us a complete picture of algebra. He also worked extensively with light and laid the foundation for geometrical optics. In explaining the refraction of light he put forward his "principle of least time" to predict the path followed by a "ray of light". This principle and its variants will show up again in our story. He lived from 1601 to 1665. Author: Dan Thomas email: Last Updated: Thursday, July 4, 1996

PIERRE DE FERMAT Yogita Chellani Term Paper, History of Mathematics, Rutgers The French mathematician Pierre de Fermat(1601-1665) was possibly the most productive mathematician of his era, making many contributions, some of which were to calculus, number theory, and the law of refraction. We will survey those contributions here, paying particular attention to his work in number theory. While relatively little is known of Fermat's early education, it is known that he was of Basque origin and received his primary and secondary education at the monastery of Grandsl ve, run by the Cordeliers (Franciscans), in Beaumont-de-Lomagne. For his advanced studies he first attended the University of Toulouse before moving to Bordeaux in the second half of the 1620's. In Bordeaux (1629) Fermat began his first serious mathematical researches, where he gave a copy of his restoration of Appollonius's Plane Loci to one of the mathematicians there. In Bordeaux he contacted Beaugrand and during this time he produced work on maxima and minima. He gave his work to Etienne de'Espagnet, who shared mathematical interests with Fermat. "Fermat's offices made him a member of that social class also and entitled him to add the "de" to his name, which he did from 1631 on." (Mahoney, p.16)

Main Page See live article Alphabetical index Pierre de Fermat Pierre de Fermat August 17 January 12 ) was a French mathematician who is generally given minor credit for the development of modern calculus ; in particular, for his work regarding tangents and stationary points. His work was such that he is sometimes regarded as the "father" of, both, differential calculus and number theory . He also made notable contributions to analytic geometry and probability Fermat was born near Montauban France ; he died at Castres. Fermat worked on number theory while preparing an edition of Diophantus , and the notes and comments thereon contained the numerous theorems of considerable elegance necessary to develop the theory of numbers. Fermat is famous for his "Enigma" that was an extension of Pythagorean Theorem, also known as Fermat's Last Theorem. Together with René Descartes , Fermat was one of the two leading mathematicians of the first half of the 17th century . Independently of Descartes, he discovered the fundamental principle of analytic geometry . Through his correspondence with Blaise Pascal , he was a co-founder of the theory of probability See also: Euler's conjecture Euler's theorem Fermat's Last Theorem Fermat's little theorem ...

Pierre de Fermat Pierre de Fermat was born in 1601 in the French town of Beaumont-de-Lomange. Since he was born into a wealthy family, Fermat received his education from a local monastery, and then he studied University of Toulouse. It may seem strange that the instigator of such an infamous problem was not a professional mathematician at all; rather, he was a lawyer. In fact, Fermat was a rather high ranking official in the French government, and he was even appointed to the Parliament of Toulouse. It was not Fermat's accomplishments as a lawyer that made him famous, however. In his free time, he devoted his attention to the pursuit of mathematics, and it seems that he was quite gifted in this area. Fermat has been dubbed "The Prince of Amateurs" by E.T. Bell, and he has left his mark on the mathematical world in his contributions to mathematics. For example, it was through the correspondence of Fermat and Blaise Pascal that the mathematical representations of the laws of probability were born. Also, it is a common belief that Sir Isaac Newton independently developed the mathematics known as calculus, but a note written by Newton (discovered in 1934) revealed that Newton based his ideas of differential calculus on "Monsieur Fermat's method of drawing tangents."* Even though Fermat's contributions to these branches of mathematics are extremely important, his most profound work involved the theory of numbers. Fermat was particularly interested in the behavior of numbers, and he enjoyed solving problems in an old text written by Diophantus, the famous Greek mathematician. The name of the text was the

Pierre de Fermat From `A Short Account of the History of Mathematics' (4th edition, 1908) by W. W. Rouse Ball. While Descartes was laying the foundations of analytical geometry, the same subject was occupying the attention of another and not less distinguished Frenchman. This was Fermat. Pierre de Fermat , who was born near Montauban in 1601, and died at Castres on January 12, 1665, was the son of a leather-merchant; he was educated at home; in 1631 he obtained the post of councillor for the local parliament at Toulouse, and he discharged the duties of the office with scrupulous accuracy and fidelity. There, devoting most of his leisure to mathematics, he spent the remainder of his life - a life which, but for a somewhat acrimonious dispute with Descartes on the validity of certain analysis used by the latter, was unruffled by any event which calls for special notice. The dispute was chiefly due to the obscurity of Descartes, but the tact and courtesy of Fermat brought it to a friendly conclusion. Fermat was a good scholar, and amused himself by conjecturally restoring the work of Apollonius on plane loci. Except a few isolated papers, Fermat published nothing in his lifetime, and gave no systematic exposition of his methods. Some of the most striking of his results were found after his death on loose sheets of paper or written in the margins of works which he had read and annotated, and are unaccompanied by any proof. It is thus somewhat difficult to estimate the dates and originality of his work. He was constitutionally modest and retiring, and does not seem to have intended his papers to be published. It is probable that he revised his notes as occasion required, and that his published works represent the final form of his researches, and therefore cannot be dated much earlier than 1660. I shall consider separately (i) his investigations in the theory of numbers; (ii) his use in geometry of analysis and of infinitesimals; and (iii) his method for treating questions of probability.

Intro Leonhard Euler Pierre de Fermat Carl Friedrich Gauss Sophia Kowalewskaja Leonardo da Vinci Isaac Newton ... Mathematicians Pierre de Fermat Pierre de Fermat lived in the early 17th century. Like Descartes who lived at the same time and was also French, Fermat studied law. Mathematically they even made some of the same discoveries. For example, Fermat started using the coordinate system a few years earlier than Descartes. But Descartes was the one who spread its use, so it got his name. Fermat was very talented in linguistics and mathematics. He was especially interested in number theory; how different numbers are built up and how we can take them apart. He made a number of discoveries on this subject. Below are a couple of examples: n p-1 =1 mod p if p is a prime number With modular arithmetic we can easily see that his statement is correct: let's take p=5 if n=1, then 1 =1 mod 5 if n=2, then 2 = 16 = 1 mod 5 if n=3, then 3 = 81 = 1 mod 5 etc. Any prime number that can be expressed as p=4n+1 (that's the same as 1 mod 4), can also be expressed as the sum of two squares. Let's see if that really works.

Pierre had a brother and two sisters and was almost certainly brought up in the town of his birth. Although there is little evidence concerning his school education it must have been at the local Franciscan monastery. He attended the University of Toulouse before moving to Bordeaux in the second half of the 1620s. In Bordeaux he began his first serious mathematical researches and in 1629 he gave a copy of his restoration of Apollonius 's Plane loci to one of the mathematicians there. Certainly in Bordeaux he was in contact with Beaugrand Pierre de Fermat. For the remainder of his life he lived in Toulouse but as well as working there he also worked in his home town of Beaumont-de-Lomagne and a nearby town of Castres. From his appointment on 14 May 1631 Fermat worked in the lower chamber of the parliament but on 16 January 1638 he was appointed to a higher chamber, then in 1652 he was promoted to the highest level at the criminal court. Still further promotions seem to indicate a fairly meteoric rise through the profession but promotion was done mostly on seniority and the plague struck the region in the early 1650s meaning that many of the older men died. Fermat himself was struck down by the plague and in 1653 his death was wrongly reported, then corrected:-
