German: [ˈalbɐt ˈaɪnʃtaɪn] ( listen);
14 March 1879–18 April 1955) was a theoretical physicist, philosopher
and author who is widely regarded as one of the most influential
and best known scientists and intellectuals of all time. He is often
regarded as the father of modern physics. He received the 1921 Nobel
Prize in Physics "for his services to Theoretical Physics,
and especially for his discovery of the law of the photoelectric
effect."

Albert Einstein
His many contributions to physics include the special and general
theories of relativity, the founding of relativistic cosmology,
the first post-Newtonian expansion, explaining the perihelion advance
of Mercury, prediction of the deflection of light by gravity and
gravitational lensing, the first fluctuation dissipation theorem
which explained the Brownian movement of molecules, the photon theory
and wave-particle duality, the quantum theory of atomic motion in
solids, the zero-point energy concept, the semiclassical version
of the Schrödinger equation, and the quantum theory of a monatomic
gas which predicted Bose–Einstein condensation.
Einstein published more than 300 scientific and over 150 non-scientific
works. Einstein additionally wrote and commentated prolifically
on various philosophical and political subjects. |
