General relativity (GR, also known as the general theory of relativity or GTR) is the geometric theory of gravitation published by Albert Einstein in and the current description of gravitation in modern physics. Introduction to general relativity - Mathematics of general relativity - Curvature. Albert Einstein, in his theory of special relativity, determined that the laws of physics are the same for all non-accelerating observers, and he showed that the speed of light within a vacuum is the same no matter the speed at which an observer travels.

Albert Einstein's general theory of relativity is one of the towering achievements of 20th-century physics. Published in , it explains that what we perceive as the force of gravity in fact arises from the curvature of space and time. Einstein proposed that objects such as the sun and the Earth change this geometry. Some of these simpler equations are appropriate to the level of this book, which means you can learn how to do some general relativity.

They will be derived. 29 Oct - 3 min - Uploaded by FUSION One hundred years ago, Albert Einstein completed his general theory of relativity, which. The special theory of relativity was a first step for Einstein. The fuller development of his goal ofrelativizing physics came with his general theory of relativity. For years, the general theory of relativity has been a pillar of modern physics. The basic idea is so elegant that you don't need superpowers to understand it.

To celebrate its centenary we asked physicist David Tong of the University of Cambridge to explain what general relativity is and how Einstein's. General relativity (GR), also known as the General Theory of Relativity, is an extension of special relativity, dealing with curved coordinate.
