Biography
Fermat was born in the first decade of the 17th century in Beaumont-de-Lomagne, Franceâ€”the late 15th-century mansion where Fermat was born is now a museum. He was from Gascony, where his father, Dominique Fermat, was a wealthy leather merchant, and served three one-year terms as one of the four consuls of Beaumont-de-Lomagne. His mother was Claire de Long.WEB,weblink When Was Pierre de Fermat Born? {{!, Mathematical Association of America|website=www.maa.org|access-date=2017-07-09}} Pierre had one brother and two sisters and was almost certainly brought up in the town of his birth. There is little evidence concerning his school education, but it was probably at the CollÃ¨ge de Navarre in Montauban.{{citation needed|date=April 2018}}File:Beaumont-de-Lomagne - Monument Ã Fermat.jpg|thumb|Monument to Fermat in Beaumont-de-LomagneBeaumont-de-LomagneFile:Capitole Toulouse - Salle Henri-Martin - Buste de Pierre de Fermat.jpg |thumb|Bust in the Salle Henri-Martin in Capitole de ToulouseCapitole de ToulouseHe attended the University of OrlÃ©ans from 1623 and received a bachelor in civil law in 1626, before moving to Bordeaux. In Bordeaux he began his first serious mathematical researches, and in 1629 he gave a copy of his restoration of Apollonius's De Locis Planis to one of the mathematicians there. Certainly in Bordeaux he was in contact with Beaugrand and during this time he produced important work on maxima and minima which he gave to Ã‰tienne d'Espagnet who clearly shared mathematical interests with Fermat. There he became much influenced by the work of FranÃ§ois ViÃ¨te.In 1630, he bought the office of a councillor at the Parlement de Toulouse, one of the High Courts of Judicature in France, and was sworn in by the Grand Chambre in May 1631. He held this office for the rest of his life. Fermat thereby became entitled to change his name from Pierre Fermat to Pierre de Fermat. Fluent in six languages (French, Latin, Occitan, classical Greek, Italian and Spanish), Fermat was praised for his written verse in several languages and his advice was eagerly sought regarding the emendation of Greek texts.He communicated most of his work in letters to friends, often with little or no proof of his theorems. In some of these letters to his friends he explored many of the fundamental ideas of calculus before Newton or Leibniz. Fermat was a trained lawyer making mathematics more of a hobby than a profession. Nevertheless, he made important contributions to analytical geometry, probability, number theory and calculus.BOOK, Essential Calculus Early Transcendental Functions, Larson, Hostetler, Edwards, Richard Stratton, 2008, 978-0-618-87918-2, U.S.A, 159, Secrecy was common in European mathematical circles at the time. This naturally led to priority disputes with contemporaries such as Descartes and Wallis.BOOK, Ball, Walter William Rouse, A short account of the history of mathematics, General Books LLC, 1888, 978-1-4432-9487-4, Anders Hald writes that, "The basis of Fermat's mathematics was the classical Greek treatises combined with Vieta's new algebraic methods."{{citation | last = Faltings | first = Gerd | authorlink = Gerd Faltings | issue = 7 | journal = Notices of the American Mathematical Society | mr = 1335426 | pages = 743â€“746 | title = The proof of Fermat's last theorem by R.

Fermat's pioneering work in analytic geometry (Methodus ad disquirendam maximam et minimam et de tangentibus linearum curvarum) was circulated in manuscript form in 1636 (based on results achieved in 1629),Daniel Garber, Michael Ayers (eds.), The Cambridge History of Seventeenth-century Philosophy, Volume 2, Cambridge University Press, 2003, p. 754 n. 56. predating the publication of Descartes' famous La gÃ©omÃ©trie (1637), which exploited the work.NEWS,weblink Pierre de Fermat {{!, Biography & Facts|work=Encyclopedia Britannica|access-date=2017-11-14|language=en}} This manuscript was published posthumously in 1679 in Varia opera mathematica, as Ad Locos Planos et Solidos Isagoge (Introduction to Plane and Solid Loci).Gullberg, Jan. Mathematics from the birth of numbers, W. W. Norton & Company; p. 548. {{isbn|0-393-04002-X}} {{isbn|978-0393040029}}In Methodus ad disquirendam maximam et minimam and in De tangentibus linearum curvarum, Fermat developed a method (adequality) for determining maxima, minima, and tangents to various curves that was equivalent to differential calculus.WEB, Pellegrino, Dana, Pierre de Fermat,weblink 2008-02-24, Florian Cajori, "Who was the First Inventor of Calculus" The American Mathematical Monthly (1919) Vol.26 In these works, Fermat obtained a technique for finding the centers of gravity of various plane and solid figures, which led to his further work in quadrature.(File:Pierre de Fermat.png|thumb|left|upright|Pierre de Fermat)Fermat was the first person known to have evaluated the integral of general power functions. With his method, he was able to reduce this evaluation to the sum of geometric series.{{citation | last1 = ParadÃs | first1 = Jaume | last2 = Pla | first2 = Josep | last3 = Viader | first3 = PelegrÃ | issue = 1 | journal = Revue d'Histoire des MathÃ©matiques | mr = 2493381 | pages = 5â€“51 | title = Fermat's method of quadrature | url =weblink | volume = 14 | year = 2008 }}{{Dead link|date=April 2019 |bot=InternetArchiveBot |fix-attempted=yes }} The resulting formula was helpful to Newton, and then Leibniz, when they independently developed the fundamental theorem of calculus.{{Citation needed|date=February 2008}}In number theory, Fermat studied Pell's equation, perfect numbers, amicable numbers and what would later become Fermat numbers. It was while researching perfect numbers that he discovered Fermat's little theorem. He invented a factorization methodâ€”Fermat's factorization methodâ€”as well as the proof technique of infinite descent, which he used to prove Fermat's right triangle theorem which includes as a corollary Fermat's Last Theorem for the case n = 4. Fermat developed the two-square theorem, and the polygonal number theorem, which states that each number is a sum of three triangular numbers, four square numbers, five pentagonal numbers, and so on.Although Fermat claimed to have proven all his arithmetic theorems, few records of his proofs have survived. Many mathematicians, including Gauss, doubted several of his claims, especially given the difficulty of some of the problems and the limited mathematical methods available to Fermat. His famous Last Theorem was first discovered by his son in the margin in his father's copy of an edition of Diophantus, and included the statement that the margin was too small to include the proof. It seems that he had not written to Marin Mersenne about it. It was first proven in 1994, by Sir Andrew Wiles, using techniques unavailable to Fermat.Although he carefully studied and drew inspiration from Diophantus, Fermat began a different tradition. Diophantus was content to find a single solution to his equations, even if it were an undesired fractional one. Fermat was interested only in integer solutions to his Diophantine equations, and he looked for all possible general solutions. He often proved that certain equations had no solution, which usually baffled his contemporaries.{{Citation needed|date=April 2015}}Through their correspondence in 1654, Fermat and Blaise Pascal helped lay the foundation for the theory of probability. From this brief but productive collaboration on the problem of points, they are now regarded as joint founders of probability theory.WEB, O'Connor, J. J., Robertson, E. F., The MacTutor History of Mathematics archive: Pierre de Fermat,weblink 2008-02-24, Fermat is credited with carrying out the first ever rigorous probability calculation. In it, he was asked by a professional gambler why if he bet on rolling at least one six in four throws of a die he won in the long term, whereas betting on throwing at least one double-six in 24 throws of two dice resulted in his losing. Fermat showed mathematically why this was the case.Eves, Howard. An Introduction to the History of Mathematics, Saunders College Publishing, Fort Worth, Texas, 1990.The first variational principle in physics was articulated by Euclid in his Catoptrica. It says that, for the path of light reflecting from a mirror, the angle of incidence equals the angle of reflection. Hero of Alexandria later showed that this path gave the shortest length and the least time.BOOK, Kline, Morris, Mathematical Thought from Ancient to Modern Times, Oxford University Press, New York, 1972, 167â€“168, 978-0-19-501496-9, Fermat refined and generalized this to "light travels between two given points along the path of shortest time" now known as the principle of least time.WEB, Fermat's principle for light rays,weblinkweblink" title="web.archive.org/web/20160303235551weblink">weblink March 3, 2016, 2008-02-24, For this, Fermat is recognized as a key figure in the historical development of the fundamental principle of least action in physics.

File:Fermats will.jpg|thumb|upright|Holographic will handwritten by Fermat on 4 March 1660 â€” kept at the Departmental Archives of Haute-Garonne, in ToulouseToulouseTogether with RenÃ© Descartes, Fermat was one of the two leading mathematicians of the first half of the 17th century. According to Peter L. Bernstein, in his book Against the Gods, Fermat "was a mathematician of rare power. He was an independent inventor of analytic geometry, he contributed to the early development of calculus, he did research on the weight of the earth, and he worked on light refraction and optics. In the course of what turned out to be an extended correspondence with Pascal, he made a significant contribution to the theory of probability. But Fermat's crowning achievement was in the theory of numbers."BOOK, Bernstein, Peter L., Against the Gods: The Remarkable Story of Risk, John Wiley & Sons, 1996, 61â€“62, 978-0-471-12104-6, Regarding Fermat's work in analysis, Isaac Newton wrote that his own early ideas about calculus came directly from "Fermat's way of drawing tangents."BOOK, Simmons, George F., Calculus Gems: Brief Lives and Memorable Mathematics, Mathematical Association of America, 2007, 98, 978-0-88385-561-4, Of Fermat's number theoretic work, the 20th-century mathematician AndrÃ© Weil wrote that: "what we possess of his methods for dealing with curves of genus 1 is remarkably coherent; it is still the foundation for the modern theory of such curves. It naturally falls into two parts; the first one ... may conveniently be termed a method of ascent, in contrast with the descent which is rightly regarded as Fermat's own."Weil 1984, p.104 Regarding Fermat's use of ascent, Weil continued: "The novelty consisted in the vastly extended use which Fermat made of it, giving him at least a partial equivalent of what we would obtain by the systematic use of the group theoretical properties of the rational points on a standard cubic."Weil 1984, p.105 With his gift for number relations and his ability to find proofs for many of his theorems, Fermat essentially created the modern theory of numbers.See also
