ALBERT EINSTEIN

NOBEL PRIZE IN PHYSICS: ALBERT EINSTEIN 1879-1955
Albert Einstein (March 14, 1879 – April 18, 1955) was one of the greatest minds in world history. Einstein is known as a brilliant physicist who contributed more to the scientific world than any other person. His theories on relativity paved the way for how science currently views time, space, energy and gravity. Einstein was so advanced in his thinking that his studies and work set the standards for the control of scientific energy and space explorations currently being studied in the field of astrophysics.
Albert Einstein was born on 14 March 1879 in Ulm, Wurttemberg, Germany. Albert Einstein’s most noted contribution to the world is his the theory of relativity. By 1902, Einstein was working on combining time and space, matter and energy. Einstein showed how mass and energy were equivalent. In 1905, Einstein submits his paper ‘The Electrodynamics of Moving Bodies’ to the leading Germany Physics Journal introduced the special theory of relativity, a theory of time, distance, mass and energy, which was consistent with electromagnetism, but omitted the force of gravity. At the age 26, he applies his theory to mass and energy and formulas equation e=mc2.

In 1905, at the age of 26, he set forth his theory of relativity, which discards the concept of time and space as absolute entities, and views them as relative to moving frames of reference. At the same time, he postulated light quanta or photons, comparable to energy quanta, and on these based his explanation of the photoelectric effect.

After 1905, Einstein continued working in this area. He made important contributions to quantum theory, but he sought to extend the special theory of relativity to phenomena involving acceleration. The key appeared in 1907 with the principle of equivalence, in which gravitational acceleration was held to be indistinguishable from acceleration caused by mechanical forces.

In 1911, he asserted the equivalence of gravitation and inertia. In 1916, he completed the mathematical formulation of this general theory of relativity, which included gravitation as a determiner of curvature of space-time continuum and represented gravitation as a field rather than a force. The second paper built upon the theory of kinetics. Einstein explained how atoms were responsible for the buffering of particles of material in suspension, such as cigarette smoke suspended in air. This paper presented the first direct evidence for the existence of atoms vindicating an idea over 2000 years old.

In March 1916, he published his paper ‘General relativity’ describing s profound way of interpreting the action of gravity. His mathematical equations showed how mass can warp space. Einstein predicted the warping of space would effect the way objects moved. He predicted that the sun, being massive would warp space around it and bend the light of distant stars that passed close to it.

In 1921, he won the Nobel Prize for his contributions to theoretical physics, especially for his work on the photoelectric effect. Einstein sought a unified field theory, whereby the phenomena of gravitation and electromagnetism could be derived from one set of equations. After 1920, however, while retaining relatively as a fundamental concept, theoretical physicists focused more attention on the theory of quantum mechanics.

In 1950, he presented his unified field theory, which attempts to explain gravitation, electromagnetism and subatomic phenomena in one set of laws, as they are infinite and obey the inverse-square law. He completed its mathematical formulation in 1953, just two years before his death in 1955 at the age of 76.
