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.
The structure of the membrane is now known in great detail, including 3D models of many of the hundreds of different proteins that are bound to the membrane. These major developments in cell physiology placed the membrane theory in a position of dominance and stimulated the imagination of most physiologists, who now apparently accept the theory ...
A micrograph from a Transmission Electron Micrograph showing a lipid vesicle. The two dark bands are the two leaflets comprising the bilayer. Similar images taken in the 1950s and 1960s confirmed the bilayer nature of the cell membrane. Thus, by the early twentieth century the chemical, but not the structural nature of the cell membrane was known.
Rather, he argued that mass-energy equivalence was a necessary and sufficient condition to resolve the paradox. In his demonstration, Einstein provided a derivation of mass-energy equivalence that was distinct from his original derivation. Einstein began by recasting Poincaré's abstract mathematical argument into the form of a thought experiment:
Albert Einstein at the home library of Paul Ehrenfest in Leiden, the Netherlands, in 1916. Albert Einstein (1879–1955) was a renowned theoretical physicist of the 20th century, best known for his special and general theories of relativity.

The following outline is provided as an overview of and topical guide to Albert Einstein: Albert Einstein – German-born theoretical physicist. He developed the theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics). [1] [2]: 274 Einstein's work is also known for its influence on the philosophy of science.
Einstein analyzed a dynamic equilibrium being established between opposing forces. The beauty of his argument is that the final result does not depend upon which forces are involved in setting up the dynamic equilibrium. In his original treatment, Einstein considered an osmotic pressure experiment, but the same conclusion can be reached in ...
