Like so many great mathematicians, he was a child prodigy and pursued many different avenues of intellectual endeavour throughout his life. But Pascal was also a mathematician of the first order. As a young man, he built a functional calculating machine, able to perform additions and subtractions, to help his father with his tax calculations.

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 s. He received a degree in civil law and he purchased the offices of councillor at the parliament in Toulouse.

So by Fermat was a lawyer and government official in Toulouse and because of the office he now held he became entitled to change his name from Pierre Fermat to 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 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.

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 s meaning that many of the older men died.

Fermat himself was struck down by the plague and in his death was wrongly reported, then corrected: 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: But he is rather preoccupied, he does not report cases well and is confused.

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. Pierre de Fermat, one of the prominent mathematicians of the 17th century, is better known for his contribution towards development of infinitesimal calculus. He was also a lawyer in terms of profession at the Parliament of Toulouse. The Life of Fermat. Pierre de Fermat was born in in Beaumont-de-Lomagne, France. 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.

Of course Fermat was preoccupied with mathematics. He kept his mathematical friendship with Beaugrand after he moved to Toulouse but there he gained a new mathematical friend in Carcavi.

Fermat met Carcavi in a professional capacity since both were councillors in Toulouse but they both shared a love of mathematics and Fermat told Carcavi about his mathematical discoveries.

In Carcavi went to Paris as royal librarian and made contact with Mersenne and his group. In addition Fermat wrote: I will share all of this with you whenever you wish and do so without any ambition, from which I am more exempt and more distant than any man in the world.

It is somewhat ironical that this initial contact with Fermat and the scientific community came through his study of free fall since Fermat had little interest in physical applications of mathematics.

Even with his results on free fall he was much more interested in proving geometrical theorems than in their relation to the real world. His reputation as one of the leading mathematicians in the world came quickly but attempts to get his work published failed mainly because Fermat never really wanted to put his work into a polished form.

The widening correspondence between Fermat and other mathematicians did not find universal praise. He wrote angrily to Fermat but although Fermat gave more details in his reply, Frenicle de Bessy felt that Fermat was almost teasing him. However Fermat soon became engaged in a controversy with a more major mathematician than Frenicle de Bessy.

He claimed that Descartes had not correctly deduced his law of refraction since it was inherent in his assumptions. To say that Descartes was not pleased is an understatement. Fermat proved correct and eventually Descartes admitted this writing: For example, although he wrote to Fermat praising his work on determining the tangent to a cycloid which is indeed correctDescartes wrote to Mersenne claiming that it was incorrect and saying that Fermat was inadequate as a mathematician and a thinker.

The period from to was one when Fermat was out of touch with his scientific colleagues in Paris. There are a number of reasons for this. Firstly pressure of work kept him from devoting so much time to mathematics. Secondly the Fronde, a civil war in France, took place and from Toulouse was greatly affected.

Finally there was the plague of which must have had great consequences both on life in Toulouse and of course its near fatal consequences on Fermat himself. However it was during this time that Fermat worked on number theory.

In November Wiles again claimed to have a correct proof which has now been accepted. Unsuccessful attempts to prove the theorem over a year period led to the discovery of commutative ring theory and a wealth of other mathematical discoveries.

Their short correspondence set up the theory of probability and from this they are now regarded as joint founders of the subject. Fermat however, feeling his isolation and still wanting to adopt his old style of challenging mathematicians, tried to change the topic from probability to number theory.Pierre de Fermat was an illustrious seventeenth century mathematician whose contribution in developing infinitesimal calculus was a milestone.

Also he played a pivotal role in the development of analytic geometry, optics and probability. His monumental work is considered to be Fermat’s Last Theorem and Fermat’s principle for light propagation.

Number theory has always fascinated amateurs as well as professional mathematicians. In Number theory, branch of mathematics concerned with properties of the positive integers (1, 2, 3, ). Sometimes called “higher arithmetic,” it is among the oldest and most natural of mathematical pursuits.

Pierre de Fermat; Number theory in the. Pierre de Fermat was one of the greatest mathematicians in history, making highly significant contributions to a wide range of mathematical topics. Pierre de Fermat (French: [pjɛːʁ də fɛʁma]) (Between 31 October and 6 December – 12 January ) was a French lawyer at the Parlement of Toulouse, France, and a mathematician who is given credit for early developments that led to infinitesimal calculus, including his technique of leslutinsduphoenix.comion: University of Orléans (LL.B., ).

Pierre de Fermat, one of the prominent mathematicians of the 17th century, is better known for his contribution towards development of infinitesimal calculus. He was also a lawyer in terms of profession at the Parliament of Toulouse.

The Life of Fermat. Pierre de Fermat was born in in Beaumont-de-Lomagne, France. Fermat's Last Theorem was until recently the most famous unsolved problem in mathematics. In the midth century Pierre de Fermat wrote that no value of n greater than 2 could satisfy the.
