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 [a] (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 Einsteinhaus on the Kramgasse in Bern, Einstein's residence at the time. Most of the papers were written in his apartment on the first floor above the street level. At the time the papers were written, Einstein did not have easy access to a complete set of scientific reference materials, although he did regularly read and contribute reviews to Annalen der Physik.
A hallmark of Albert Einstein's career was his use of visualized thought experiments (German: Gedankenexperiment [1]) as a fundamental tool for understanding physical issues and for elucidating his concepts to others. Einstein's thought experiments took diverse forms. In his youth, he mentally chased beams of light.
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.

Although it is now understood that Einstein's response to Kretschmann was mistaken (subsequent papers showed that such a theory would still be usable), another argument can be made in favor of general covariance: it is a natural way to express the equivalence principle, i.e., the equivalence in the description of a free-falling observer and an ...

These two papers are the last in which Einstein allows time to be warped while keeping space flat (uncurved). In these papers, he realizes that the Lorentz transformations of special relativity must be generalized and that the new theory of gravitation must be nonlinear, since gravitational energy can itself gravitate.
