General relativity is a beautiful scheme for describing the gravitational fleld and the equations it obeys. Nowadays this theory is often used as a prototype for other, more intricate constructions to describe forces between elementary particles or other branches of fundamental physics. This is why in an introduction to general relativity it is of
Special and General Principle of Relativity. The basal principle, which was the pivot of all our previous considerations, was the special principle of relativity, i.e. the principle of the physical relativity of all uniform motion. Let as once more analyse its meaning carefully.
General relativity is the theory of space and time and gravity. The essence of the theory is simple: gravity is geometry. The effects that we attribute to the force of gravity are due to the bending and warping of spacetime, from falling cats, to orbiting spinning planets, to the motion of the cosmos on the grandest scale. The purpose of
The theory of relativity is a theory Albert Einstein created in the early 1900s. There are two theories of relativity. The first is special relativity and the second is general relativity . The theory tries to solve problems which could not be solved by Classical physics, or by 19th century physics. Some things, like the orbit of Mercury or the ...
String Theory For Dummies 2009-11-16 Genius demystified, the Dummies way! In 1905, Albert Einstein revolutionized modern physics with his theory of relativity. He went on to become a twentieth-century icon-a man whose name and face are synonymous with genius.
We write the squared distance between two spacetime points as ds2= |d~x|2≡ g(d~x,d~x) = d~x·d~x. (40) IThis equation, true in any basis because it is a scalar equation that makes no reference to components, is taken as the definition of the metric tensor. Up to now the metric could have been any symmetric (0,2) tensor.

But it wasn't quite like that - because the history of science is dreadfully tedious sub"ect, we will skip Albert's many predecessors and get ...
