Thales of Miletus ( BC) Thales was the Chief of the Seven Sages of ancient Greene. He has been called the “Father of Science,” the “Founder of Abstract Geometry,” and the “First Philosopher”. Thales is believed to have studied mathematics under Egyptians.

Theorems about triangles are attributed to Thales. One of these theorems include The Law of Similar Triangles. The Law of Similar Triangles was famously used to calculate the height of the Great Pyramid. Also another famous theorem is “Thales’ Theorem,” which is the fact that any angle inscribed in a semicircle is a right angle. Contributions to the field of mathematics

It is said that Thales proved his theorem “Thales Theorem” by sacrificing an ox to celebrate what might have been the very first mathematical proof. Thales was not only a mathematician, but he also invented the 365 day calendar, and he is the first person believed to have accurately predicted a solar eclipse. Thales was also a politician. Facts

Brook Taylor (18 August 1685 – 29 December 1731) Brook Taylor was born in Edmonton. He died in London, England. He went to an institution called St. John's College in Cambridge. Brook Taylor was best known for Taylor's Theorem and also the Taylor Series.

Contributions to the Field of Mathematics Brook Taylor is known for Taylor's Theorem and the Taylor Series. Taylor's Theorem's importance went unrecognized until J.L Lagrange then discovered the powers of Taylor's Theorem and termed it as “the main foundation of differential calculus”.

Emilie Du Chatelet December 17, September 10, 1749 Emilie was born in Paris. In spite of Emilie's talents in language, she stuck with mathematics. She was encouraged by a family friend, M. de Mezieres. She got married to Marquis du Châtelet at the age of 19.

Contributions to the Field of Mathematics -She coauthored Voltaire’s Elements de la philosophie de Newton (1736) -At the time of her death, she was working on her translation of, and commentaries on, Newton’s Philosophiae naturalis principia mathematica. -In 1740, she published a book Institutions de physique
