Albert Einstein And His Theories :: essays research papers

Albert encephalon and His TheoriesEinstein, Albert (1879-1955), German-born American physicist and Nobellaureate, best known as the creator of the special and general theories ofrelativity and for his bold hypothesis concerning the particle nature of lightly.He is perhaps the close to well-known scientist of the 20th century.Einstein was born in Ulm on demo 14, 1879, and spent his youth inMunich, where his family owned a small computer storage that manufactured electric machinery.He did not talk until the age of three, except even as a youth he showed a promising curiosity about nature and an ability to understand difficult mathematical concepts. At the age of 12 he taught himself Euclidean geometry.Einstein detested the dull regimentation and unimaginative spirit of schoolin Munich. When repeated stock failure led the family to leave Germany forMilan, Italy, Einstein, who was then 15 years old, apply the opportunity towithdraw from the school. He spent a year with his pare nts in Milan, and when itbecame clear that he would have to make his own way in the world, he finishedsecondary school in Arrau, Switzerland, and entered the Swiss bailiwickPolytechnic in Zrich. Einstein did not enjoy the methods of pedagogics there.He often cut classes and used the time to study physics on his own or to playhis beloved violin. He passed his examinations and gradatory in 1900 by studyingthe notes of a classmate. His professors did not think passing of him and wouldnot recommend him for a university do.For two years Einstein worked as a tutor 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 scarce eventually divorced. Einstein later remarried.Early Scientific PublicationsIn 1905 Einstein received his doctorate from the University of Zrichfor a theoretical disquisition on the dimensions of molecules, and he alsopu blished three theoretical paper of central importance to the development of20th-century physics. In the first of these papers, on Brownian motion, he madesignificant predictions about the motion of particles that are randomlydistributed in a fluid. These predictions were later confirmed by experiment.The second paper, on the photoelectrical effect, contained a revolutionaryhypothesis concerning the nature of light. Einstein not wholly proposed that undercertain circumstances light can be considered as consisting of particles, but healso hypothesized that the energy carried by any light particle, called a photon,is proportional to the frequency of the radiation.
