Einstein Triangle. The energy–momentum relation is consistent with the familiar mass–energy relation in both its interpretations: E = mc 2 relates total energy E to the (total) relativistic mass m (alternatively denoted m rel or m tot), while E 0 = m 0 c 2 relates rest energy E 0 to (invariant) rest mass m 0.
Albert Einstein (/ ˈ aɪ n s t aɪ n /, EYEN-styne; [4] German: [ˈalbɛʁt ˈʔaɪnʃtaɪn] ⓘ; 14 March 1879 – 18 April 1955) was a German-born theoretical physicist who is best known for developing the theory of relativity. Einstein also made important contributions to quantum mechanics.
[3] [4] Einstein is best known by the general public for his mass–energy equivalence formula E = mc 2 (which has been dubbed "the world's most famous equation"). [5] 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 ", a pivotal step in ...
Albert Einstein presented the theories of special relativity and general relativity in publications that either contained no formal references to previous literature, or referred only to a small number of his predecessors for fundamental results on which he based his theories, most notably to the work of Henri Poincaré and Hendrik Lorentz for special relativity, and to the work of David ...
In 1918, Einstein developed a general theory of the process by which atoms emit and absorb electromagnetic radiation (the Einstein coefficients), which is the basis of lasers (light amplification by stimulated emission of radiation) and shaped the development of modern quantum electrodynamics, the best-validated physical theory at present.
He has authored several books, including Theory and Applications of the Poincaré Group, Phase Space Picture of Quantum Mechanics, Physics of the Lorentz Group, New Perspectives on Einstein's E = mc2, and Mathematical Devices for Optical Sciences. [3] [4] Kim is an honored member of the International Association of Top Professionals (IAOTP). [5]
The psychology of learning refers to theories and research on how individuals learn. There are many theories of learning. Some take on a more behaviorist approach which focuses on inputs and reinforcements. [1] [2] [3] Other approaches, such as neuroscience and social cognition, focus more on how the brain's organization and structure influence ...
Olinto De Pretto (26 April 1857 – 16 March 1921) was an Italian industrialist and geologist from Schio, Vicenza.It is claimed by an [additional citation(s) needed] Italian mathematician, Umberto Bartocci, [1] [2] that De Pretto may have been the first person to derive the energy–mass-equivalence =, generally attributed to Albert Einstein.
