Modern actuaries and insurers are indebted to Fermat and his friend, Blaise Pascal, for a branch of mathematics developed in a spirit of frivolity. This site will also tell you more about the other mathematicians mentioned on this page, including Blaise Pascal. Everyone failed to see that Fermat had been hoping his specific problems would lead them to discover, as he had done, deeper theoretical results. In fact, his given birth name was Pierre Fermat, and it wasn't until he achieved official government status that he was qualified to change his name to Pierre de Fermat. There is some doubt as to the precise date of his birth. Fermat moved to Bordeaux, France for a few years in the 1620s, where he undertook an informal study of mathematics, but ultimately settled on law as a profession, receiving his Bachelors degree in Civil Law from the University of Orleans.

It approaches the curved area ever more closely as the size of the intervals approaches zero, i. He kept his mathematical friendship with after he moved to Toulouse but there he gained a new mathematical friend in. After that, he moved to Bordeaux, and at that point the historic facts of his life become more concrete. It was his connection with Marin Mersenne that gave Pierre international recognition. Fermat applied the methods of algebra to geometry using a coordinate system in his study of loci.

However some of his methods were published, for example added a supplement containing Fermat's methods of maxima and minima to his major work Cursus mathematicus. Many of those scholars are still well-known today, such as Pascal, Mersenne, and Descartes. Diophantus was content to find a single solution to his equations, even if it were an undesired fractional one. Fermat's Last Theorem Fermat greatly contributed to the study of mathematics in various fields, such as analytic geometry, differential calculus, theory of probability, and number theory. Little is known of his childhood, except that he was the son of a prosperous merchant and the beneficiary of a classical secondary education. I guess we could say that Fermat has truly marvelous mathematical accomplishments which this lesson is too small to contain! This was first published in 1638 and was used for finding centers of gravity.

This process is now called integral calculus. Of all the mathematical fields, number theory was probably his favorite. Fermat Numbers and Fermat Primes Another area that Fermat made great advancements in is in the field of optics. Convinced that the latter could always be provided, Fermat seldom attempted to carry them out, with the result in several cases that he failed to see how the use of algebra had led to the introduction of concepts quite foreign to the classical tradition. In 1648 he was promoted to king's counselor in the Parliament of Toulouse, a post which he held until his death on Jan. Pierre had a brother and two sisters and was almost certainly brought up in the town of his birth.

Castres, France, 12 January 1665 mathematics. He discovered that he could also show that every prime of the form 4 k + 1 could be expressed as the sum of two squares by denying the proposition for some such prime, deriving another such prime less than the first, for which the proposition would again not hold, and so on. There are a number of reasons for this. For suppose some number of the form 4 k + 1 could not be written as the sum of two squares. You can find out more about Pierre de Fermat by visiting the excellent.

He held this office for the rest of his life. Fermat thus reduces the problem to one of determining point H such that that sum is minimized. Fermat identified a subset of numbers, now known as Fermat numbers, which are of the form of one less than 2 to the power of a power of 2, or, written mathematically, 2 2 n + 1. The curve, as Fermat shows, is a uniquely defined ellipse. Fermat was a trained lawyer making mathematics more of a hobby than a profession. Despite the inheritance, Pierre de Fermat continued to work and had started researching mathematics, starting with restoration of Apollonius's De Locis Planis and sent it to mathematicians such as Jean de Beaugrand and Étienne d'Espagnet. As sympathetic a reader as Huygens could make little sense of it.

He had the habit of scribbling notes in the margins of books or in letters to friends rather than publishing them. As a result Fermat increasingly returned to the isolation from which he had so suddenly emerged in 1636, and his death in 1665 was viewed more as the passing of a grand old man than as a loss to the active scientific community. In developing a method of finding tangents to curves and determining the area bounded by curves, Fermat laid the groundwork for both differential calculus and. Hence, the proposition must hold. The terms and Fermat functional were named in recognition of this role. Mathematics from the birth of numbers, W.

The truth of Fermat's assertion was proved in June 1993 by the British mathematician , but withdrew the claim to have a proof when problems emerged later in 1993. In so doing, he also found many lesser but still important results. The Method of Maxima and Minima. Pierre de Fermat After that, in 1620 Fermat went to Bordeaux and started his research in many mathematical topics. This procedure enabled hi m to find tangents to curves and locate maximum, minimum, and inflection points of polynomials Kolata. A 1654 letter from Pascal, in which the latter requested Fermat's help with a problem involving consecutive throws of a die, led to a series of communications in which the two men set down the elements of probability theory. He was the inventor of modern number theory, and this was where a lot of his work was concentrated.

Eric Temple Bell, Men of Mathematics 1937 , contains a chapter on Fermat. Having earned his degree in from the latter, he began his law practice, and with the purchase of several key posts started a climb to the upper echelons of French jurisprudence. Pierre de Fermat contributed to the development of various theories in mathematics, including number theory, theory of probability, little theorem and laws of refraction, and many more. Alongside Blaise Pascal, he established the foundations of probability theory, which is the mathematics of gambling, risk and change. For example, to follow the shortest path, light passing through a bowl of water would travel in a straight line; but observation shows that this is not true.
