The History of Classical Gravitational Theory and General Relativity In the beginning scientists and religious men of their era tried to explain the universe both biblically and scientifically. One of the foremost Greek scientists was Aristotle; taught by Plato, that the circle and sphere are the two most perfect shapes in a 2 and 3 dimensional universe, Aristotelian system placed Earth at the center of the universe; and all other heavenly bodies revolved around the earth in crystalline orbitals. Another Greek Mathematician, Aristarchus theorized that the sun was the center of the universe and that the Earth revolved around it. His simple reasoning was constituted purely by the fact that the Earth is a much smaller body than†¦show more content†¦Ã¢â‚¬Å"The English physicist and chemist Henry Cavendish determined the value of the universal constant of gravitation, made noteworthy electrical studies, and is credited with the discovery of hydrogen and the composition of water. â€Å" (http://www.notablebiographies.com/Ca-Ch/Cavendish-He nry.html) The Cavendish Experiment was the first exerpiment to calculate the earths gravitational constant. His experiment resulted in the following conclusion Or that the gravitational Constant of Earth = Acceleration of gravity at the surface of the Earth times the Earth’s Radius squared over its mass = 3 times Acceleration of gravity at the surface of the Earth over 4 pi times the radius of the Earth times its density. One hundred years ago Albert Einstein published a theory so monumental and eventually leading to the creation of the Nuclear Bomb, satellite technology, space travel, and a better understanding of the universe. Einstein soon became the most famous physicist in history, by publishing his most profound theory, the Theory of General Relativity. General relativity states that energy is equal to mass times the speed of light squared or †¦ E=MC2 This equation proves that a small amount of matter can emit a huge amount of energy. The equation also explains why the sun shines, the big bang theory, and further clarifies the speed of light to be 3x108 m/s. butShow MoreRelatedEssay about Edward Wittens Work Led to a Revolution721 Words   |  3 PagesWitten was born in Baltimore, Maryland. He is the son of Lorraine (Wollach) Witten and Louis Witten, a theoretical physicist specializing in gravitation and general relativity.[3] Witten attended the Park School of Baltimore (class of 68), and received his Bachelor of Arts with a major in history and minor in linguistics from Brandeis University in 1971. He published articles in The New Republic and The Nation. In 1968, Witten published an article in The Nation arguing that the New Left had no strategyRead MoreAlbert Einstein Essay1119 Words   |  5 PagesAlbert Einstein Einstein, Albert (1879-1955), was one of the greatest scientists of all time. He is best known for his theory of relativity, which he first advanced when he was only 26. He also made many other contributions to science. Einsteins relativity theory revolutionized scientific thought with new conceptions of time, space, mass, motion, and gravitation. He treated matter and energy as exchangeable, not distinct. In so doing, he laid the basis for controlling the release of energyRead MoreHow to Acquire Knowledge1388 Words   |  5 Pagessimilar by converting electric energy into thermal kind of energy. Of course physicist of that time knew that as well but what concerned them was how much energy exactly was stored in the oven. By using laws of thermodynamics and theory of black body radiation (both theories valid even today) scientists got that energy was infinite. Something was wrong. How one simple oven can contain infinite energy? Well it cannot. First one who explained this phenomena was Max Planck, but in order to do so he hadRead MoreThe Is Worth The Time Or Money For Students Essay2068 Words   |  9 PagesThe higher education institution in this country has been an ongoing evolution since the fo unding of our nation.

In the eighteenth century the same possibility was mentioned by Isaac Newton in the General Scholium that concludes his Principia. Making a comparison to the Sun s planets, he wrote And if the fixed stars areRead MoreCompilation of Mathematicians and Their Contributions11615 Words   |  47 Pageswhich would today be called Number Theory. * Setting up a secret mystical society, known as the Pythagoreans that taught Mathematics and Physics.
