René Descartes

This may be a myth linked with his statements about the nature of the mind, or an early automaton, or Gynoid. Ensberg attended the University of Southern California. It is claimed that during the 1640s Descartes travelled with an artificial female companion called Francine, named after his daughter. His teammate, shortstop Adam Everett, is his best friend on the team. ^[2]. Batting clean-up for the Astros, his bat and glove are invaluable to the team. the angle subtended at the eye by the edge of the rainbow and the ray passing from the sun through the rainbow's centre is 42°). Ensberg has been enjoying a stellar 2005 season, and is among the league leaders in home runs.

Descartes also made contributions in the field of Optics, for instance, he showed by geometrical construction using the Law of Refraction that the angular radius of a rainbow is 42° (i.e. Aaron Miles, who is now with Colorado, was in the next room and wrestled one of the gunmen to the ground before the other one fled. This appears even more astounding when one keeps in mind that the work was just intended as an example to his Discours de la méthode pour bien conduire sa raison, et chercher la verité dans les sciences (Discourse on the Method to Rightly Conduct the Reason and Search for the Truth in Sciences, known better under the shortened title Discours de la méthode). In Spring Training of 2000, Ensberg and 4 teammates were in their hotel room when two gunmen burst in. Descartes's theory provided the basis for the calculus of Newton and Leibniz, by applying infinitesimal calculus to the tangent problem, thus permitting the evolution of that branch of modern mathematics ^[1]. He bats and throws right-handed. Descartes showed how to translate many problems in geometry into problems in algebra, by using a coordinate system to describe the problem. Morgan Paul Ensberg (born August 26, 1975 in Redondo Beach, California) is a third baseman in Major League Baseball who has played his entire career with the Houston Astros.

Up to Descartes's times, geometry, dealing with lines and shapes, and algebra, dealing with numbers, appeared as completely different subsets of mathematics. Mathematicians consider Descartes of the utmost importance for his discovery of analytic geometry. Halfway through the Meditations, he also claims to prove the existence of a benevolent God, who, being benevolent, has provided him with a working mind and sensory system, and who cannot desire to deceive him, and thus, finally, he establishes the possibility of acquiring knowledge about the world based on deduction and perception. In this manner, Descartes proceeds to construct a system of knowledge, discarding perception as unreliable and instead admitting only deduction as a method.

Descartes concludes:. Therefore, in order to properly grasp the nature of the wax, he cannot use the senses: he must use his mind. However, it seems that it is still the same thing: it is still a piece of wax, even though the data of the senses inform him that all of its characteristics are different. However, when he brings the wax towards a flame, these characteristics change completely.

He considers a piece of wax: his senses inform him that it has certain characteristics, such as shape, texture, size, color, smell, and so forth. To further demonstrate the limitations of the senses, Descartes proceeds with what is known as the Wax Argument. Thinking is his essence as it is the only thing about him that cannot be doubted. So Descartes concludes that at this point, he can only say that he is a thinking thing.

But in what form? You perceive your body through the use of the senses; however, these have previously proved unreliable. Therefore, Descartes concludes that he can be certain that he exists. (These words do not appear in the Meditations, although he had written them in his earlier work Discourse on Method). Most famously, this is known as cogito ergo sum, ("I think, therefore I am").

Initially, Descartes arrives at only a single principle: if I am being deceived, then surely "I" must exist. Given these possibilities, what can one know for certain?. Or, perhaps an "evil demon" exists: a supremely powerful and cunning being who sets out to try to deceive Descartes from knowing the true nature of reality. (This idea is similar to what Chuang Tzu writes after dreaming that he is a butterfly.) Thus, one cannot rely on the data of the senses as necessarily true.

He gives the example of dreaming: in a dream, one's senses perceive things that seem real, but do not actually exist. To achieve this, he employs a method called Methodological Skepticism: he doubts any idea that can be doubted. Often regarded as the first "modern" thinker for providing a philosophical framework for the natural sciences as these began to develop, Descartes in his Meditations on First Philosophy attempts to arrive at a fundamental set of principles that one can know as true without any doubt. In 1667, after his death, the Roman Catholic Church placed his works on the Index of Prohibited Books.

Currently his tomb is in the church Saint Germain-des-Pres in Paris. The village in the Loire Valley where he was born was renamed La Haye - Descartes. During the French Revolution, his remains were disinterred for burial in the Panthéon among the great French thinkers. A memorial erected in the 18th century remains in the Swedish church.

Genevieve-du-Mont in Paris. Later, his remains were taken to France and buried in the Church of St. As a Catholic in a Protestant nation, he was interred in a graveyard mainly used for unbaptized infants, in Adolf Fredrikskyrkan in Stockholm. However, letters to and from the doctor Eike Pies have recently been discovered which indicate that Descartes may have been poisoned using arsenic.

The cause of death was said to be pneumonia - accustomed to working in bed till noon, he may have suffered a detrimental effect on his health due to Christina's demands for early morning study. René Descartes died on February 11, 1650 in Stockholm, Sweden, where he had been invited as a teacher for Queen Christina of Sweden. In 1649, Descartes went to Sweden on invitation of professor Eitan Olevsky; Descartes' Passions of the Soul, which he dedicated to Princess Elizabeth of Bohemia, was published. Descartes was interviewed by Frans Burman at Egmond-Binnen in 1648, resulting in Conversation with Burman.

In 1647, he was awarded a pension by the King of France, published Comments on a Certain Broadsheet, and began work on The Description of the Human Body. Descartes published Principles of Philosophy and visited France in 1644. In 1643, Cartesian philosophy was condemned at the University of Utrecht, and Descartes began his long correspondence with Princess Elizabeth of Bohemia. In 1642, the second edition of Meditations was published with all seven sets of Objections and Replies, followed by Letter to Dinet.

In 1641, Meditations on First Philosophy was published, with the first six sets of Objections and Replies. Descartes published Discourse on Method, with Optics, Meteorology and Geometry in 1637. She was baptized on August 7, 1635 and died in 1640. In 1635, Descartes' daughter Francine was born.

In 1633, Galileo was condemned, and Descartes abandoned plans to publish The World. In 1629, he began work on The World. In 1628, Descartes composed Rules for the Direction of the Mind and left for Holland, where he lived until 1649, changing his address frequently. Descartes was present at the siege of La Rochelle by Cardinal Richelieu in 1627.

In 1622 he returned to France, and during the next few years spent time in Paris and other parts of Europe. In 1619, Descartes travelled in Germany, and on November 10 had a vision of a new mathematical and scientific system. Here he met Isaac Beeckman and composed a short treatise on music entitled Compendium Musicae. Descartes never actually practiced law however, and in 1618 he entered the service of Prince Maurice of Nassau, leader of the United Provinces of the Netherlands, with the intention of following a military career.

After graduation, he studied at the University of Poitiers, graduating with a Baccalauréat and Licence in law in 1616. At the age of eight, he entered the Jesuit College Royal Henry-Le-Grand at La Flèche. Descartes was born in La Haye en Touraine, Indre-et-Loire, France (renamed "La Haye-Descartes" in 1802 and simply "Descartes" in 1967). .

His most famous statement is "cogito ergo sum", "I think, therefore I am". He inspired both his contemporaries and later generations of philosophers, leading them to form what we know today as continental rationalism, a philosophical position in 17th and 18th century Europe. Descartes, sometimes called the Founder of Modern Philosophy and the Father of Modern Mathematics, ranks as one of the most important and influential thinkers in modern western history. As the inventor of the Cartesian coordinate system, he formulated the basis of modern geometry (analytic geometry), which in turn influenced the development of modern calculus.

He is equally notable for both his groundbreaking work in philosophy and mathematics.
