A Physics Special On Mass Energy Equivalence - 718 Words

The Great Lakes Tribune A Physics Special on Mass-Energy Equivalence Article By: Hugh Corley History Born in Germany in 1879, Albert Einstein was theoretical physicist. After graduating high school, he began working in a Swiss patent office in 1903. 1905 was like any other year in the patent office. That is, until September 27, when Albert Einstein finished a paper that would revolutionize physics. Titled â€Å"Does the Inertia of a Body Depend Upon Its Energy-Content?† it was the final paper in a series of four he submitted that year to the German physics journal, Annalen der Physik. The first three papers explained the photoelectric effect, gave experimental proof of the atoms, and introduced the theory of special relativity. In the fourth paper however, Einstein explained the idea of mass-energy equivalence, using the now famous equation E=mc2. Although the idea of mass-energy equivalence existed before Einstein, it was never realized and systematically consolidated to a single equation. iii Explanation Figure 1: The Rest Mass Energy Equation.ii This equation states that that the energy of the system (E) is equivalent to the mass of the system (m) times the speed of light squared. In short, mass and energy are separate quantities that are closely related. So close, in fact, that they are physically equivalent to each other. An increase in energy yields a proportional increase in inertial mass. However it is important to note that the matter remains unchanged.

At age five, Einstein received his first compass, and his fascination with it ignited a spark within him to investigate the natural world. As a child, Einstein was interested in math and science and excelled in these are as due to a self-education program he created.

After Einstein completed his Special Theory of Relativity, he moved onto creating the General Theory of Relativity which earned him the Nobel Prize in Physics in 1921. With the creation of both the General Theory of Relativity and the Special Theory of Relativity, Einstein was able to create his Theory of Relativity which comprises of both theories.

He did however score exceptionally beyond the average on math and science, so he was admitted provided he complete his secondary education. His primary study was in line with becoming a professor of physics and he studied under the hea d professor of physics, Heinrich Friedrich Weber. Despite the renown of Weber, Einstein retreated to his old methodology of independent study when he learned Weber denied many of the new contributions to science. It was at the Polytechnic schoolRead MoreImportant Discoveries in Physics Essay2329 Words   |  10 Pages Ideas in the subject of Physics are never absolute; it is a forever-changing topic. We think we have discovered everything there is to know about it, and then we find out something new that changes everything. That is one of the reasons physics is so interesting to learn about – there will always be something new. There are many very important discoveries in Physics. This paper will describe some of the discoveries. These discoveries are prevalent throughout history and in our daily lives.

He was able to obtain his diploma in 1901 and become a technical assistant in the Swiss Patent Office (Nobel Prize). In 1905 he obtained his doctor’s degree, and in that same year, was able to publish four scientific papers that would go on to become some of the most important works in science. One of these introduced the theory of relatively, while another one introduced his formula of mass and energy (Albert Einstein: A life spent re-imagining physics).

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 abo ve 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 the laws of Physics whenRead More Albert Einstein Essay500 Words   |  2 Pages This German born physicist is considered one of the world’s greatest thinkers in history. Not only did he shape the way people think of time, space, matter, energy, and gravity but he also was a supporter of Zionism and peaceful living. Einstein was born on March 14, 1879 in Ulm Germany, and spent most of his youth living in Munich, where his family owned a small electric machinery shop. He attended schooling in Munich, which he found unimaginative and dull.

He treated matter and energy as exchangeable, not distinct. In so doing, he laid the basis for controlling the release of energy from the atom. Thus, Einstein was one of the fathers of the nuclear age. Einsteins famous equation, E equals m times c-squared (energy equals mass times the velocity of light squared), became a foundation stone in the development of nuclear energy.

He kept this job from 1902 until 1909, and it was during this time that he completed a great deal of his deep thoughts on physics. One year after he obtained his job at the Patent office, in 1903, Albert Einstein married his sweetheart from Zà ¼rich Poly, Mileva Marie. The two had a daughter before they were married, a daughter which was given up for adoption the same year
