e=mc^2
E = mc2 is a famous equation called mass–energy equivalence raised by Albert einstein ,which explain the relationship between energy (E)and mass(m),c is represented constant number of light speed.
E = mc2 theory of relativity theory and quantum mechanics are two basic branch of modern physics , classical mechanics laid the foundation of classical physics , but for high speed objects and microscopic condition of objects, Newton's laws are no longer applicable.
An important conclusion of the theory of relativity is talking about mass and energy. Based on the special relativity ,mass and energy are not interchangeable, while in classical mechanics, mass and energy are mutually independent, but in relativistic mechanics, energy and mass are interchangeable.
Albert Einstein(14 March 1879 – 18 April 1955) was a German-born theoretical physicist, came up with some of the most important discoveries and theories in all of science.Some people consider him to be one of the smartest people of the 20th century. Not only best known for formula E = mc2 for his services to theoretical physics, but also laid much of the foundation for modern physics. here are example of his discoveries. In 1905, Einstein came up with the concept that light is made up of particles called photons. Most scientists of his day didn't agree, but later experiments in 1919 showed this to be the case. This became an important discovery for many branches of science and he was awarded the Nobel Prize for Physics in 1921. working with another scientist called Satyendra Bose, they discovered another state of matter. Sort of like liquid or gas or solid states.
In January 1933 after the Nazi regime in Germany, grab, Einstein move to university of Princeton and 1940 he became U.S. citizen. In 1939, he was informed that its uranium nuclear fission chain reaction found in the Hungarian physicist L. Szilard, driven by a letter to President Roosevelt, the proposed development of the atomic bomb,

    Ultimately, the total amount of energy available is a constant. Einstein’s equation, , describes the relationship between energy and matter. In the equation, energy (E) is equal to matter (m) times the square of a constant (c). Energy and matter are interchangeable in Einstein’s equation and due to the constant the equation also indicates that there is a fixed quantity of energy and matter, (Boulle, 2012).…

    One of the most controversial things about Einstein was his involvement in the creation of the atomic bomb used in the assault on Japan during World War Two (Physics Central, 1). Although many people are convinced he invented the bomb its self, this is not true. In 1905 as a part go his Special Theory of Relativity he made the point that a large amount of energy could be released by a small amount of matter. He created the formula E=mC2 to demonstrate this. Twenty four years later Einstein publicly announced that no matter what the circumstances, he would never help in a war effort, directly or indirectly. Soon Hitler came into power in the Germany. This made the situation personal for Einstein, because Germany was his original home and many members of his family still resided there (Einstein and the First World War, 2). Einstein sent a letter directly to President Roosevelt explaining that he believed it was crucial they build an atomic bomb, because he had intel claiming that Germany had already begun to construct their own weapon of mass destruction. (Elert, 1) Although Einstein developed…

    The 1920’s was revolutionized by many historical characters, but the most influential was Albert Einstein. As a kid, he was always attracted to the universe and he never lost his passion, even through adulthood (“Einstein, Albert” 2). He was determined to solve the universe's problems, and this made him one of the most important scientists to ever live. Despite the fact Einstein disliked school, he had a deep passion for mathematics and an orderly universe which led to his many revolutionary theories, one of which changed physics forever; all of his hard work led to many awards and the evolution of theoretical physics.…

    Albert Einstein, born March 14th 1879, in Ulm, Kingdom of Wurttemberg, German Empire, died April 18th 1955, in Princeton, New Jersey, USA, is remember as one of the most influential physicists of all time and the father of modern physics. Sir Isaac Newton who produced the Newtonian mechanics influenced Einstein; this led to Einstein’s development of the special theory of relativity. This theory was later expanded to gravitational fields. Einstein is best known for his mass-energy equivalence formula E = mc2 (1), this has been dubbed “the worlds most famous equation”(1). He received the Nobel Prize in Physics “for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect.”(2) That discovery led to establishing the quantum theory within physics. In 1917, Einstein applied the general theory of relativity (which he published a paper on) to make a model of the universe as a whole. (3) Einstein’s scientific career is extremely extensive; throughout his life he published hundreds of books and articles. (4)(5) He also did multiple collaborations with other scientists including the Bose- Einstein statistics, the Einstein refrigerator and many others. A list of the most major contributions that Einstein had on modern physics:…

    Albert Einstein was a famous scientist, Physicist &Genius. Einstein was born in Ulm, Germany. In 1880 the Einstein family moved to Munich. In 1886 he started elementary school in a Catholic public school. In 1894, his family moved to Milan, leaving him in Munich to finish school. The next year, Albert left school without finishing to find his family in Italy. In 1895 he enrolled in high school in Aarau, Switzerland. The next year he meets his future wife, Mileva Maric, at Zurich technical institute. Albert applied for Swiss citizenship in 1899 and was granted that citizenship in 1901. In 1902 many events happened in Albert's life. He moved to Bern to teach mathematics, his father died, and his first daughter was born. In 1909 Albert received an honorary doctorate from the University of Geneva and in 1911 he accepted a full professorship at the University of Prague. The Einstein family moved to Berlin in 1914, right before World War I started. In 1918, Albert went to visit his family in Zurich, where they moved prior to WW I. Albert and Mileva are divorced the next February. Many things happen over the next 20 years. Including his remarriage, several visits to the US where he received a research fellowship at Oxford University, and he becomes a professor at Princeton. In 1936 Albert's second wife, Elsa, dies. Three years later, World War II breaks out and Einstein moves to America and becomes a US citizen in 1940. Eight years later his doctor discovered an aortic aneurysm in his abdomen. Einstein is informed that if it bursts he will die. In 1952, Einstein was invited to become president of Israel, but he refuses. On April 18, 1955 Einstein dies in his sleep after refusing surgery on his ruptured…
