A physicist of the 20th century whose major accomplishment to the field of physics was his finding that matter can turn into energy and vice versa and that massive particles can not travel at or above the speed of light. See also: speed of light (c), Physicists
(1879-1955) professor at Zurich, Prague, Berlin and Princeton; theory of relativity.
A German-born American physicist and mathematician who formulated the Relativity theories in 1905 and 1915 and carried out investigations in thermodynamics and radiation physics. In 1921, he received the Nobel Prize in physics. He became a professor of mathematics at Princeton University, New Jersey, in 1933 after fleeing Nazi Germany.
The German-American physicist who developed the Special and General Theories of Relativity that—along with quantum mechanics—are the foundation of modern physics.
German-born American physicist (1879-1955) whose theories revolutionised scientific understanding of space and time. Became famous for his special and general theories of relativity. Also showed that light is composed of individual particles, later named 'photons'.
Albert Einstein (1879-1955) was a German/American physicist. He revolutionized our conception of the universe with his Theories of Special and General Relativity. Special relativity supplanted Newtonian mechanics, yielding different results for very fast-moving objects. The Theory of Special Relativity is based on the idea that speed has an upper bound; nothing can pass the speed of light. The theory also states that time and distance measurements are not absolute but are instead relative to the observer's frame of reference. Space and time are viewed as aspects of a single phenomenon, called space-time. Energy and momentum are similarly linked. As a result, mass can be converted into huge amounts of energy, and vice versa, according to the formula E=mc. General Relativity expands the theory of special relativity to include acceleration and gravity, both of which are explained via the curvature of space-time. His theories explained the perturbations in the orbits of Mercury. Einstein won the Nobel Prize in 1921 for explaining the photoelectric effect.
A Swiss mathematician and physicist who lived from 1879 – 1955. Einstein was born in Germany to Jewish parents, and after moving to Switzerland, he took a job at a patent office. When he began publishing scientific papers, he quickly rose to fame and was recognized as a leading thinker of the time. He held several different professorial positions in Switzerland, Germany, and the United States during his lifetime. In 1922, Einstein won a Nobel Prize for work he had done with the Photoelectric Effect. Over the course of his life, Einstein made major advances in physics, such as developing the Theory of Special Relativity and the Theory of General Relativity. He was arguably the most important physicist of the 20th century. See also: Relativity, Special
(1879-1955) – German-American physicist; developed the special and general theories of relativity which, along with quantum mechanics, is the foundation of modern physics.
Developed mathematical theories to explain the behavior of planetary motion and the movement of electrical particles; after 1900 issued theory of relativity. (p. 715)
