In theories of quantum gravity, the graviton is the hypothetical elementary particle that mediates the force of gravitational interaction. There is no complete quantum field theory of gravitons due to an outstanding mathematical problem with renormalization in general relativity.
It was first published in German in 1916 and later translated into English in 1920. [1] [2] [3] It is divided into three parts, the first dealing with special relativity, the second dealing with general relativity, and the third dealing with considerations on the universe as a whole. There have been many versions published since the original in ...
Only Einstein's theory proved to be consistent with experiments and observations. To understand the theory's basic ideas, it is instructive to follow Einstein's thinking between 1907 and 1915, from his simple thought experiment involving an observer in free fall to his fully geometric theory of gravity. [1]
The lectures were translated into English by Edwin Plimpton Adams. The lectures and the subsequent book were Einstein's last attempt to provide a comprehensive overview of his theory of relativity and is his only book that provides an accessible overview of the physics and mathematics of general relativity .
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.
Former Connecticut Gov. M. Jodi Rell, who took over the office to become the second female governor in state history after her predecessor resigned amid a corruption scandal, has died. She was 78.
Jalen Milroe passed for two touchdowns and ran for a third in just over two quarters to help No. 9 Alabama beat FCS team Mercer 52-7 on Saturday. Ryan Williams ran for a 29-yard touchdown and ...
[3] [4] Einstein is best known by the general public for his mass–energy equivalence formula E = mc 2 (which has been dubbed "the world's most famous equation"). [5] He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect ", a pivotal step in ...
