Albert Einstein’s vs. Newton General Theory of Relativity

Albert Einstein’s vs. Newton: General Theory of Relativity Albert Einstein, most famously known as a physicist, was a contributor to the scientific world with his many known researches and humanitarian work. As a Nobel Prize Winner in 1921, his chronicled and more important works include Special Theory of Relativity (1905), Relativity (English Translation, 1920 and 1950), General Theory of Relativity (1916), Investigations on Theory of Brownian Movement (1926), and The Evolution of Physics (1938). (Nobel Prize Foundation, 1921) In all his important works, Einstein’s Theory of Relativity has lead the way for how science currently views time, space, energy, and gravity. Relativity, which all motion must†¦show more content†¦What the world line of a particle moving with constant speed in one direction? How would you describe the motion of a particle with the world line shown below? Viewing spacetime this way allows us to formulate physics in new ways. It is a similar way in getting Newton’s first law of motion, which states that an object with no force acting on it will move in a straight line at a constant and we can just say that the world line of a free object (one with no forces on it) is a straight line. speed (Harrison, pars. 6) Comparing to Newton’s laws, spacetime are considered two separate things, while in relativity, both in special and general theory, it is necessary to view spacetime as one. In GR this team of spacetime is curved by the effects of gravity. Now in GR, curved space often refers to a spatial geometry, which is not â€Å"flat.† Spacetime becomes curved in the response to the effects of matter and there is no gravitational force deflecting objects from their natural, straight paths. This puts gravity to correspond to changes in the properties of space and time, which in turn changes the straightest-possible paths that objects will naturally follow. So the act of curving is caused by the energy-momentum of matter and affects matters behaviors. In Newton’s first law of motion, it states that, where an object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the sameShow MoreRelatedRelativity Essay1956 Words   |  8 PagesRelativity is a theory in physics that can be basically implies that space and time are one in the same. This is absolutely counterintuitive to classical physics which has the two as completely different entities. Relativity can be separated into two basic concepts: Special and General Relativity. Within Relativity the fundamental concept above all else is that space and time are intertwined with each other in the universe as a fabric called space-time. Simply put, Special Relativity deals with theRead MoreEssay on Albert Einstein: Creator and Rebel2900 Words   |  12 PagesFollowing mention of those, it is then possible to look at his or her life, family, and religion as well. Howev er, for Albert Einstein, these elements must all be looked at collectively. Einstein will no doubt go down in history as a great theoretical physicist. His work is compared in importance to that of scientists such as Galileo Galilei, Nicolas Copernicus, Johannes Kepler, and Isaac Newton. Some would even say that his contributions to science were greater. However, it is impossible to paint a completeRead MoreGeography Topics3206 Words   |  13 Pagesnew theory that the solar system actually revolved around the sun.

In Steven Hawking’s â€Å"The Grand Design† and the â€Å"Theory of Everything† he discusses these mysteries that have dominated our lives since the beginning. Starting with a brief history of our understanding of the universe, he quickly delves into the topics of the big bang, black holes, the forces that govern our universe, and he addresses other theoretical theories.
