Einstein was the first physicist to say that Max Planck's discovery of the energy quanta would require a rewriting of the laws of physics.To support his point, in 1905 Einstein proposed that light sometimes acts as a particle which he called a light quantum (see photon and wave–particle duality).
Einstein himself considered the introduction of the cosmological constant in his 1917 paper founding cosmology as a "blunder". [3] The theory of general relativity predicted an expanding or contracting universe, but Einstein wanted a static universe which is an unchanging three-dimensional sphere, like the surface of a three-dimensional ball in four dimensions.
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.
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 ...
Albert Einstein's discovery of the gravitational field equations of general relativity and David Hilbert's almost simultaneous derivation of the theory using an elegant variational principle, [B 1]: 170 during a period when the two corresponded frequently, has led to numerous historical analyses of their interaction.
The loss of Einstein's citizenship allowed him to avoid service in the military, which suited his pacifist views. In response to a Manifesto of the Ninety-Three signed by 93 leading German intellectuals including Max Planck in support of the German war effort, Einstein and three others wrote a counter-manifesto.

After Team Blake's Alex Whalen dropped out for "personal reasons" and his Battle partner, Neil Salsich. advanced by default, Blake took one last dig at the coach he’d regularly teased during his ...
The war of the currents was a series of events surrounding the introduction of competing electric power transmission systems in the late 1880s and early 1890s. It grew out of two lighting systems developed in the late 1870s and early 1880s; arc lamp street lighting running on high-voltage alternating current (AC), and large-scale low-voltage direct current (DC) indoor incandescent lighting ...
