Albert Einstein(March 14, 1879 – April 18, 1955) was a German-born theoretical physicist who is widely considered to have been one of the greatest physicists of all time. While best known for the theory of relativity (and specifically mass-energy equivalence, E=mc²), Einstein was awarded the 1921 Nobel Prize in Physics “for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect.”(www.NobelPrize.org 2007)

Einstein's many contributions to physics include his special theory of relativity, which reconciled mechanics with electromagnetism, and his general theory of relativity which extended the principle of relativity to nonuniform motion, creating a new theory of gravitation. His other contributions include relativistic cosmology, capillary action, critical opalescence, classical problems of statistical mechanics and their application to quantum theory, an explanation of the Brownian movement of molecules, atomic transition probabilities, the quantum theory of a monatomic gas, thermal properties of light with low radiation density (which laid the foundation for the photon theory), a theory of radiation including stimulated emission, the conception of a unified field theory, and the geometrization of physics.

Works by Albert Einstein include more than fifty scientific papers but also non-scientific works, including About Zionism: Speeches and Lectures by Professor Albert Einstein. (1930), Why War? (1933, co-authored by Sigmund Freud), The World As I See It (1934), and Out of My Later Years (1950).^[1]

In 1999 Einstein was named Time magazine's "Person of the Century". In popular culture the name "Einstein" has become synonymous with genius.

History is the study of past human events and activities. Although this broad discipline has often been classified under either the humanities or the social sciences, it can be seen to be a bridge between them, incorporating methodologies from both fields of study. As a field of study, history encompasses many subfields and ancillary fields, including chronology, historiography, genealogy, paleography, and cliometrics. Traditionally, historians have attempted to answer historical questions through the study of written documents, although historical research is not limited merely to these sources. In general, the sources of historical knowledge can be separated into three categories: what is written, what is said, and what is physically preserved, and historians often consult all three. Historians frequently emphasize the importance of written records, which universally date to the development of writing. This emphasis has led to the term prehistory, referring to a time before written sources are available. Since writing emerged at different times throughout the world, the distinction between prehistory and history often depends on the topic. The scope of the human past has naturally led scholars to divide that time into manageable pieces for study. There are a variety of ways in which the past can be divided, including chronologically, culturally, and topically. These three divisions are not mutually exclusive, and significant overlap is often present, as in "The Argentine Labor Movement in an Age of Transition, 1930–1945". It is possible for historians to concern themselves with both very specific and very general locations, times, and topics, although the trend has been toward specialization. For others history has become a "general" term meaning the study of "everything" that is known about the human past, but even this barrier is being challenged by new fields such as big history. Traditionally, history has been studied with some practical or theoretical aim, but now it is also studied simply out of intellectual curiosity.
