Curvature In Space Time Essay

1791 Words8 Pages

Newton’s theory of gravity held its ground for more than two hundred years until Einstein published his paper on General theory of relativity in 1915. General theory of relativity gives a geometric description of gravitation. As seen today, gravity is not considered to be an alien force travelling through space and time, but as a curvature in space-time. Motion viewed by Galileo and Newton was with respect a fixed Euclidean reference frame. In this ideal frame of reference Newton and Galileo built up and described this strange force of gravity without giving a geometry description about it. But Einstein argued that there is no such force as gravity, it’s just a curvature in space-time or an observed acceleration due to this curvature in space-time. Newton Consider time as an absolute constant something which is independent of any influence, claiming this on basis of Euclidean reference frame which accounted for all of space and all of time. But Einstein said the exact …show more content…

It was natural for him to generalize the idea of WEP by arguing that there should be no way for the physicist inside the box to differentiate between gravitational field and uniform acceleration. This concept later came to be known as Einstein Equivalence principle. Hence Einstein Equivalence principle suggests that we should attribute effects of gravity to curvature of space-time. Einstein Equivalence principle also puts forth that there is no such thing a gravitationally neutral object with respect to which we can measure acceleration due to gravity. Hence it is more convenient for us to define ‘nonaccelerating bodies’ as ‘free-falling’. Therefore we may conclude that gravity is not a force because a force is something which results into acceleration. But we have defined zero acceleration to be free motion of a body in any kind of gravitational

Gravity is caused by the penetration of the centers of the sun and planets without any diminution, according to Sir Isaac Newton. Francis Bacon, English philosopher of science, believes that science make little progress because there isn’t a specific goal sciences just keep providing new discoveries.

In about one hundred years thanks to the invention of the printing press, humanity grew in knowledge so that the entire world as we know today, was practically achieved by then. In document 10, The Mathematical Papers of Isaac Newton by Derek T. Whiteside, …” He read and made notes on Galileo’s Dialoges… and Descartes’ Principles of Philosophy….As we turn the pages of his notebooks we can see his mind leap from summaries of his readings to his own principles and results... He began to think of gravity as a force extending as far as the moon...in those two years, a mathematician was born.

Einstein's response to Wright is rhetorically effective, not only for his highly effective use of Pathos, Logos, Ethos, and not to mention how he kept simple enough for Wright to read, yet profound enough for it to have left a lasting impression, so profound in fact, that we are still reading it 80 something years later. While the question of whether or not scientists pray, and on a larger note, what or to whom they pray, Einstein takes the question in stride, and manages to sincerely answer her question, without providing his own, personal, bias. On the subject of logos, Einstein manages to supply logos with a counterargument, "Scientific research is based on the idea that everything that takes place is determined by the laws of nature,

Even though Newton had to face many struggles in his early life between growing up without a father, his mother leaving to live with her new husband, and his mother then dying he was still able to accomplish and bring many new things to the world. Many of Newton 's creative ideas and inventions he brought to the world are still used today. For example, in 1666, Newton came up with the Theories of Gravity. A few years after developing The Universal Law of Gravitation, he created the three Laws of Motion. The first Law of Motion states that every object

To start with, we should make sense of what these words mean. Gravity: the power that makes something tumble to the ground (at 9.8 m/s²) Newton 's Laws of Motion: three laws that state mechanics portraying the movement of a body. The main law is the law of latency: a body stays very still unless followed up on by an outer power. The second law expresses that a body in movement stays in movement unless followed up on by an outside power. Newton 's third and last law is about how for each activity, there is an equivalent and inverse response.

In 1936, Phyllis Wright, a sixth-grader that hoped to understand what scientist prayed about, sent a letter to Albert Einstein, who responded to her inquiry with a well-thought-out letter. Within the reply, Einstein used appeals to logos, ethos, and pathos; clever manipulation of the relationship between subject, speaker, and audience; and a well-articulated purpose, all of which made Einstein’s reply rhetorically effective. Perhaps the most important observation that can be made about rhetoric in Einstein’s response is the clear imbalance of the rhetorical triangle, which describes the relationship between subject, audience, and speaker. The subject addressed within Einstein’s letter was prayer and how scientists use it, and this subject clearly

He changed the way people viewed the world. He created the Theory of General Relativity which stated that space and time are relative. This means that how much time passed depends on location and speed. Before this, people relied on Sir Isaac Newton’s view of the world. This theory also stated that pure energy equals mass times the speed of light squared or E=mc².

Newton realized that some force must have been acting on falling objects like apples because otherwise they would not start moving from rest. He also noticed the moon “flying” away from Earth in a straight line tangent to its orbit, some force was not causing it to fall toward the Earth. Newton called this force “gravity” and determined that gravitational forces exist between all objects . (standford.edu) Throughout his life he continued research into a wide range of subjects including mathematics, optics, astronomy and

Newton is best known for his contribution to physics, however the list goes on. He developed three laws of motion: the law of inertia. the law of acceleration, and the law of action. Along with his laws of motion, comes with his idea that there is a universal gravitation among the earth. Also, he developed a theory that the earth was more a spherical object with more of a flattened surface at each of its poles.

Newton’s Third Law: - ‘For every reaction, there is an equal and opposite reaction’ - (Hall, 2015). If an object (Object A) exerts a force onto another object (Object B), Object B will exert the same force back, just in the opposite direction. A finger is exerting a force on to the wall. According to Newton’s Third Law of Motion, the wall should be exerting the same amount of force, just in the opposite direction, to the finger.

After becoming famous for several brilliant advances in physics, including Brownian motion, the photoelectric effect, and the special and general theories of relativity, Albert Einstein spent the last thirty years of his life on a useless search for a way to combine gravity and electromagnetism into a single theory. Einstein was motivated by a need to unify the forces of nature. He felt that all of nature must be described by a single theory. But he never gave up on his quest for a unified theory. Even while lying on his deathbed, he continued his work.

Transcendentalism was an American literary movement that started in the early nineteenth century. A very famous transcendentalist writer was Ralph Waldo Emerson. Ralph was the central figure of the movement that brought about the movement with one of his publishing titled “Self Reliance”. He lecture about the importance of individuality. Ralph Waldo Emerson stress the importance of nonconformity by talking about the individual, famous figures of history who did not conform to their surroundings and how people will try to force conformity upon you.
