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.
He failed to reach the required standard in the general part of the test, [31] but performed with distinction in physics and mathematics. [32] On the advice of the polytechnic's principal, he completed his secondary education at the Argovian cantonal school (a gymnasium ) in Aarau , Switzerland, graduating in 1896. [ 33 ]
Einstein sensed a conflict between Newtonian mechanics and the constant speed of light determined by Maxwell's equations. [6]: 114–115 Regardless of the historical and scientific issues described above, Einstein's early thought experiment was part of the repertoire of test cases that he used to check on the viability of physical theories.
The puzzle is often called Einstein's Puzzle or Einstein's Riddle because it is said to have been invented by Albert Einstein as a boy; [1] it is also sometimes attributed to Lewis Carroll. [ 2 ] [ 3 ] However, there is no evidence for either person's authorship, and the Life International version of the puzzle mentions brands of cigarettes ...
When studying and formulating Albert Einstein's theory of general relativity, various mathematical structures and techniques are utilized. The main tools used in this geometrical theory of gravitation are tensor fields defined on a Lorentzian manifold representing spacetime. This article is a general description of the mathematics of general ...
The expedition failed. After the war, he was engaged in the construction of a solar observatory in Potsdam, the Einsteinturm, and he was director of the Einstein-Institut. In 1933 Hitler came to power and Freundlich was forced to leave Germany; he had a Jewish grandmother and his wife was Jewish.
Eleven-year-old Yusuf Shah is being hailed as a genius after he made the highest possible score, 162, on a Mensa intelligence test. 11-year-old British boy beats Einstein and Hawking on Mensa IQ ...
The Einstein–Podolsky–Rosen (EPR) paradox is a thought experiment proposed by physicists Albert Einstein, Boris Podolsky and Nathan Rosen, which argues that the description of physical reality provided by quantum mechanics is incomplete. [1]
