Pierre de Fermat was born on August 17th, 1601 in Beaumont-de-Lomagne, France. Mr. Fermat had three other siblings, one brother and two sisters. Their parents names were Dominique Fermat, the father who was a wealthy leather merchant, and Francoise de Cazelneuve, the mother (von Collani). Mr. Fermat attended school in his childhood, although not exactly sure where, it was said to have been in a local Franciscan monastery. When he turned 19, he chose to go to the University of Toulouse. Mr. Fermat did not start off with an interest for math, but once he started attending the University of Bordeaux this interest began (Aaron, Michael, and Jorge).
Mr. Fermat graduated in 1631 from the University of Orleans. Before working on his studies of math, he practiced law in his younger adult life. While doing so he married Louise Du Long, and together they had five children (Aaron, Michael, and Jorge). In his spare time, Mr. Fermat would work on his study of math, this included analytical geometry, pre-evolved calculus, and infinite descent ("Pierre de Fermat"). Mr. Fermat was best known for the Number Theory and was also known as “The Prince of Amateurs of Mathematics” (Christiaens). There were also other works like, mathematical analysis, the theory of probability, and the least time principle (Markov). These works had a big impact on mathematics today, even though Mr. Fermat was only working on these theorems and principles as an amateur hobby.
To discuss and explain a few of his works, Analytic Geometry is the study of geometry on a coordinate plane system. By understanding conic sections, Mr. Fermat gathered that there was a “standard geometrical framework” to produce the correspondence between a curve and an equation. By dividing this equation, Ax2+By2+Cxy+Dx+Ey+F= 0, he shows how each conic equation defines a curve ("Fermat, Pierre De"). During his research he focused on the geometrical structure of the curve and its equation. Although not being able to find the geometrical framework of a solid, Mr. Fermat had found and built the foundation for this system. (“Fermat, Pierre De”). Analytic geometry is now used for “investigating geometric problems”. Mr. Fermat's discovery allows one to use an equation and analyze it from the coordinate plane that is being looked at to determine a line that passes through two points and interpret it geometrically (Planetmath). This was one of the most important concepts developed in seventh-century mathematics (“Fermat, Pierre De”).
The number theory is one of the oldest and largest branches of “pure mathematics” (Dave Rusin). There are various number theories, including, the algebraic number theory, the analytic number theory, the geometric number theory, and many more. The...
