René Descartes was a brilliant man born on March 31, 1596. He was born in a small town in the south of France, called La Haye. René Descartes lived from 1596 to 1650. He was the son of an intellectual advisor to Parliament, named Joachim Descartes. His mother, Jeanne Brochard, died when he was only 1 year old. René Descartes was 8 years old when he attended the Jesuit College Henry VI in La Fleche. Rene studied science, grammar, mathematics and literature which led him to become a famous mathematician. He subsequently left La Fleche in 1614 to study civil and canon law in Poitiers. In 1616, René Descartes received his bachelor's and law degrees. In 1618, Descartes spent some time in the army where he was placed in a defense force of Maurice of Nassau, in the Dutch Republic. In 1622 Descartes returned to France. It was during this stay in Paris that he wrote his first essay entitled "Regulae ad Directionem Ingenii" also known as Rules for the Direction of the Mind. In 1628, René moved to the Dutch Republic where he lived for over 20 years. During this period of time, he learned more about mathematics, using his free time. René Descartes published many works on philosophy and mathematics in this period. He also came into contact with the school of Dordrecht's headmaster, Isaac Beeckman. However, in 1630, the two separated when René Descartes accused Beeckham of plagiarizing his original ideas. Descartes decided not to publish his work “Treatise on the World” because he had heard about the censorship of Galileo's writings in 1633 by the Catholic Church. However, he published some of his writings in his essays entitled "La Geometrie, Les Meteores and La Dioptrique". In 1641, Descartes presented his work as "Med...... middle of paper ...... with this in his books “The description of the human body” and “Passions of souls”, where he states that the body human functions like a machine because he possesses material properties. The king of France awarded Descartes a pension in 1647. After the reward, his books were banned by the pope in 1663. René had a daughter named Francine from his relationship with Helena Jans van Der Strom, who was a servant. Unfortunately, Francine died in 1640 due to scarlet fever. Descartes also died on February 11, 1650 in Stockholm, Sweden, due to pneumonia. He served as a guardian for the Queen of Sweden in the Abbey of Saint-German-des-Pres, Paris. A memorial to René Descartes was built in the Swedish church in the 18th century. René left a good legacy on the use of ideas such as geometry and the creation of x, y and z as representations of equations.
