# An introduction to the life of pierre de fermat

Firstly pressure of work kept him from devoting so much time to mathematics. Inwhile studying perfect numbers, Fermat wrote to Mersenne "if p is called prime, then 2p divides 2p Many people died in that plague and even Pierre was badly impacted. Despite his interest in mathematics, he always maintained it as a hobby while continuing to work as an active lawyer.

This is known as an inverted form of reasoning by recurrence or mathematical induction. Work on theory of numbers Fermat vainly sought to persuade Pascal to join him in research in number theory.

His proof failed, however, because it assumed incorrectly that such complex numbers can be factored uniquely into primes, similar to integers. Since they both shared a love of mathematics, Fermat told Carcavi about his mathematical discoveries Singh, page Actually, the mathematics required to solve the problem simply did not exist until the second half of the twentieth century.

Theory of Probabilities Fermat, along with Pascal, is known as the founder of Theory of Probabilities. Diophantus was content to find a single solution to his equations, even if it were an undesired fractional one. But instead of being fixed, the problem, which had originally seemed minor, now seemed very significant, far more serious, and less easy to resolve.

Another month would pass before she celebrated her sixteenth birthday. The period from to was one when Fermat was out of touch with his scientific colleagues in Paris. Frenicle de Bessy was perhaps the only mathematician at that time who was really interested in number theory but he did not have sufficient mathematical talents to allow him to make a significant contribution.

Biography[ edit ] Fermat was born in the first decade of the 17th century in Beaumont-de-LomagneFrance—the late 15th-century mansion where Fermat was born is now a museum. In addition to the law of refraction, Fermat obtained the subtangent to the ellipse, cycloid, cissoid, conchoid, and quadratrix by making the ordinates of the curve and a straight line the same for two points whose abscissae were x and x - e.

This grew out of Huygens interest in probability and the correspondence was soon manipulated by Fermat onto topics of number theory.

All in all, Fermat has been referred to as the greatest French mathematician of the first half of the seventeenth century Boyer, page I have discovered a truly marvelous demonstration [of this general theorem] which this margin is too narrow to contain" Bell, p.

Interestingly, these are all prime numbers and are known as Fermat primesbut all the higher Fermat numbers which have been painstakingly identified over the years are NOT prime numbers, which just goes to to show the value of inductive proof in mathematics.

He also contributed to the development of calculus through his work on the properties of curves. Twenty years later Fermat noted that this appeared to be in conflict with the view espoused by Aristotelians that nature always chooses the shortest path.

It became a part of the Langlands programmea list of important conjectures needing proof or disproof. He rose through the ranks at the criminal court, reaching up to the highest post in She was his cousin fourth removed, Lo uise de Long.

He wrote angrily to Fermat but although Fermat gave more details in his reply, Frenicle de Bessy felt that Fermat was almost teasing him. Fermat chose to expand on this concept by finding a maximum or minimum value of a function. He could also find the tangent to chosen points on a curve, which meant he could find the slope or gradient at points on a curved line.

From his appointment on 14 May Fermat worked in the lower chamber of the parliament but on 16 January he was appointed to a higher chamber, then in he was promoted to the highest level at the criminal court.

Once again no proof was given. Fermat was a trained lawyer making mathematics more of a hobby than a profession. Fermat did not go mad with his new found wealth. In November ofWiles again claimed to have a correct proof, which has now been accepted, and has been published.

By changing direction, the light ray travels between A and B in the least possible time. Even with his results on free fall he was much more interested in proving geometrical theorems than in their relation to the real world.

These curves in turn directed him in the middle s to an algorithmor rule of mathematical procedure, that was equivalent to differentiation. It was not until Euler took up these problems that the missing steps were filled in.

He was once thought to have been born inbut this was a different Pierre de Fermat — a half-brother who died in infancy.

Fermat met Carcavi in a professional capacity since both were councillors in Toulouse. Such a formula is: Hero of Alexandria later showed that this path gave the shortest length and the least time. Fermat was more than good enough!

This naturally led to priority disputes with contemporaries such as Descartes and Wallis.Pierre de Fermat Pierre de Fermat was born in the year in Beaumont-de-Lomages, France.

Mr. Fermat's education began in He was home schooled. Mr. Fermat was a single man through his life. Pierre de Fermat, like many mathematicians of the early 17th century, found solutions to the four.

In number theory Fermat's Last Theorem (sometimes called Fermat's conjecture, especially in older texts) states that no three positive integers a, b, and c satisfy the equation a n + b n = c n for any integer value of n greater than 2. The cases n = 1 and n = 2 have been known to have infinitely many solutions since antiquity.

This theorem was. 17th century mathematics - fermat Pierre de Fermat () Another Frenchman of the 17th Century, Pierre de Fermat, effectively invented modern number theory virtually single-handedly, despite being a small-town amateur mathematician. Dec 26,  · Pierre de Fermat Mathematician Specialty Mathematics & Law Born Beaumont-de-Lomagne, France Died Jan.

12, Castres, France Nationality French Born inPierre de Fermat was an amateur mathematician and a lawyer in the Parlement of Toulouse, France. Pierre de Fermat contributed to the development of. Pierre Fermat's father was a wealthy leather merchant and second consul of Beaumont- de- Lomagne.

There is some dispute [14] about the date of Pierre's birth as given above, since it is possible that he had an elder brother (who had also been given the name Pierre) but who died young.

Pierre had a. A Time-line for the History of Mathematics (Many of the early dates are approximates) This work is under constant revision, so come back later.
