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.
Grossman tutored Einstein on the subject, and in 1913 and 1914, they published two joint papers describing an initial version of a generalized theory of gravitation. [32] Over the next several years, Einstein used these mathematical tools to generalize Minkowski's geometric approach to relativity so as to encompass curved spacetime.
The Einstein-de Haas experiment is the only experiment concived, realized and published by Albert Einstein himself. A complete original version of the Einstein-de Haas experimental equipment was donated by Geertruida de Haas-Lorentz , wife of de Haas and daughter of Lorentz, to the Ampère Museum in Lyon France in 1961 where it is currently on ...
The essay concludes with Einstein's analysis on how to solve these problems through a planned economy: I am convinced there is only one way to eliminate these grave evils, namely through the establishment of a socialist economy, accompanied by an educational system which would be oriented toward social goals. [2]
A letter written by Albert Einstein in which he writes out his famous E = mc2 equation has sold at auction for more than $1.2 million, about three times more than it was expected to get, Boston ...
Lenard also argued that Einstein's general theory of relativity admits the existence of superluminal velocities, in contradiction to the principles of special relativity; for example, in a rotating coordinate system in which the Earth is at rest, the distant points of the whole universe are rotating around Earth with superluminal velocities.
Hamming argues that Albert Einstein's pioneering work on special relativity was largely "scholastic" in its approach. He knew from the outset what the theory should look like (although he only knew this because of the Michelson–Morley experiment ), and explored candidate theories with mathematical tools, not actual experiments.
That’s a hefty chunk of change, but it’s surprisingly low considering the global success of Apple, which has been valued at nearly $3.7 trillion. The main reason Jobs isn’t worth more is ...
