Rene Descartes

Rene Descartes Rene Descartes was a brilliant cosmos. His works on philosophy, physics and maths are aloneeviate heavily influenced much to every last(predicate) of these studies today in our modern world. Descartes was born in March 31, 1596 in La Haye, France he was named by and by one of his godfathers, Rene Bruchard des Funtaines. Descartes parents were Joachim and Jeanne Descartes, he also had one brother and one sister and two half(a) siblings. Growing up Descartes had health issues infirmity of the lungs, (Rene Descartes). When he was enrolled in school around eight historic period of age at Jesuit college La Fleche in Anjou he had permission to wake up at eleven in the morning sort of of earlier like all the other school kids, in regards to his fragile health. Descartes kept this daily routine for almost the rest of his life he believed that, the only instruction to good work in mathematics and to preserve his health was never to allow anyone to make him purport up in the morning before he felt inclined to do so an judicial decision which I chronicle for the benefit of any schoolboy into whose hands this work may fall, (A Short Account of the record of Mathematics). Descartes left school at around 1912 and they began to study law at Poiters, and graduated with honors for his full stop and license in law, although he didnt pursue a law degree. In 1617 Descartes chose to join the military rather than the church He served in the army of Prince Maurice of Orange and then Breda. He was more of a mercenary for the Catholics and Protestants. One day in late fall of 1618, Descartes was walking around and saw a Dutch placard, which spiked his curiosity and by luck the person he stopped was Isaac Beckman.Beckman was a highly educated Dutch philosopher he translated for Descartes in return if Descartes would work out the problem. After a suspender of hours passed, intrigued by Descartes, Beckman sparked his interest in mathematics and the New Physi cs, he concluded that his real path in life was the pursuit of true wisdom and science, (17th Century Mathematics-Descartes). During his leisure time in the army, Descartes studied mathematics in November 10th-11th, 1619 he had a series of dreams that he believed is one or the most important years of his life.The visions he had were his first ideas of new philosophy and his works of analytical geometry. He continued to serve in the army under his family traditions and influence and was persuaded to volunteer under Count de Bucquoy in the army of Bavaria, and then he resigned his commission in 1621. Descartes traveled throughout parts of Europe for a couple of years still purely giving himself to mathematics in 1628 while residing in France he met Cardinal de Berulle, the founders of the Oratorians. Berulle loved his communion with Descartes, and he encouraged Descartes to devote his life to the study of truth, (Rene Descartes-Biography). For the nest twenty years Descartes lived in seclusion in Holland and made regular trips to France. In the course of time Descartes wrote a piece of his collections, Le Monde, he didnt want it to be published in that time because the Catholic church had burnt all of Galileos Dialogue Concerning the Two Chief World Systems (1632) and him in house arrest. Descartes had lived in fear the same thing could happen to him if he didnt correspond with the principles. Yet he was handwriting Le Monde was published many years later.Despite not being commensurate to release that book, he did write another book in 1633 and was published in 1937. In 1637 Descartes published Optics, Meteorology, and Geometry, a collection of essays. The preface to the collection is name Discourse on the Method of Rightly Conducting the Reason and Seeking the Truth in the Sciences, (Rene Descartes-Biography). La Geometrie is what his component part to mathematics is still utilise till this day. Before his discovery mathematicians used capital lett ers (A,B,C) for know quantities in algebraic notation and unknown quantities were lower case letters (a,b,c).In the La Geometrie he gave his ideas and instead of using capital and lower cases letters, he shifted it to just (a,b,c) as know quantities and (x,y,z) for unknown. In that time he also in verbal expression of exponents such as straightforwardly, cube at etc, he replaced it with issue superscripts. Descartes argued that, For the square of a magnitude did not differ from it in kind, as a geometrical square differs from a line, rather, the square the cube and all powers differed from the base quantity only in the event of dealing separating them respectively from a common unit quantity.That is since 1 x=x x2 =x2 x3= (Descartes Mathematics and Physics) Descartes rule of signs a law given for determining whether the number of positivistic or negative real roots of polynomials Descartes rule of signs does not give the solution of a polynomial equation, but it does give infor mation on the number of positive and negative roots of the polynomial, (17th Century Mathematics-Descartes). He also proposed in La Geometrie that each tear down in a two dimension form can have two numbers on a plane, giving a horizontal and vertical locations which is known as Cartesian coordinates. He used perpendicular lines (or axes) crossing at a point called the origin, to measure the horizontal (x) and vertical (y) locations, both positive and negative, thus effectively diving the plane into four quadrants, (17th Century Mathematics-Descartes). With the Cartesian Coordinates, Descartes showed that the x and y axis supported simple equations of straight lines, to more complex coordinates of equations with different exponents. For example y=x2+4 is a curve parabola. Descartes was more famously known as a philosopher giving his two sense in things and pursuing to uphold the truth.He continued to keep adding to his collections of writing Meditations, Principia Philosophiae a nd others. In 1649, Queen Christina of Sweden invited Descartes to live in capital of Sweden to tutor her in philosophy and she insisted in working with him at 5 in the morning which he was used. The early hours and the harsh weather affected his health and he died of pneumonia in early 1650. Besides his extensive deal of being dubbed the father of modern day philosophy Descartes math contributions are value of us today.His idea of the Cartesian coordinate is in our mathematical calculators and the coordinates are what we use in math in almost all grade levels. Without Descartes influence exponents wouldnt have been as simple, and also being able to determine positive and negative real roots. Descartes believed everything can be related to math and that there was unceasingly an answer, even if it was imaginary numbers too. His contributions in all areas of studies helped shaped the modern studies. Rene Descartes was a brilliant man indeed. Works CitedBall, W. W Rouse.
