Albert Einstein And His Theories :: essays research papers
Albert brain and His TheoriesEinstein, Albert (1879-1955), German-born American physicist and Nobellaureate, best know as the creator of the special and general theories ofrelativity and for his bold supposition concerning the particle nature of light.He is perhaps the most well-kn bear scientist of the twentieth century.Einstein was born in Ulm on March 14, 1879, and spent his young person inMunich, where his family owned a small shop that manufactured electric car machinery.He did not talk until the duration of three, but even as a youth he showed abrilliant curiosity well-nigh nature and an ability to understand difficultmathematical concepts. At the age of 12 he taught himself Euclidean geometry.Einstein hated the dull regimentation and stereotyped spirit of schoolin Munich. When repeated business failure light-emitting diode the family to leave Germany forMilan, Italy, Einstein, who was then 15 years old, used the opportunity to assume from the school. He spent a year with his parents in Milan, and when itbecame clear that he would have to make his own way in the world, he finishsecondary school in Arrau, Switzerland, and entered the Swiss NationalPolytechnic in Zrich. Einstein did not enjoy the methods of instruction there.He practically cut classes and used the time to study physics on his own or to playhis beloved violin. He passed his examinations and graduated in 1900 by studyingthe notes of a classmate. His professors did not think highly of him and wouldnot remember him for a university position.For two years Einstein worked as a initiate and substitute teacher. In 1902he secured a position as an examiner in the Swiss patent office in Bern. In 1903he married Mileva Mari, who had been his classmate at the polytechnic. They hadtwo sons but eventually divorced. Einstein subsequent remarried.Early Scientific PublicationsIn 1905 Einstein received his doctors degree from the University of Zrichfor a theoretical dissertation on the dimensions o f molecules, and he alsopublished three theoretical papers of central immenseness to the development of20th-century physics. In the first of these papers, on Brownian motion, he made satisfying predictions about the motion of particles that are randomlydistributed in a fluid. These predictions were later confirmed by experiment.The second paper, on the photoelectric effect, contained a revolutionisthypothesis concerning the nature of light. Einstein not only proposed that under true circumstances light can be considered as consisting of particles, but healso hypothesized that the energy carried by any light particle, called a photon,is proportionate to the frequency of the radiation.
