Gravity: an introduction to Einstein's General Relativity James B. Hartle
Publisher: Benjamin Cummings

It describes gravity as a geometric property of the fabric of spacetime. A physicist and historian of science. But Einstein believed the Universe was static and so added a term that would provide some kind of . May 8, 2014 - It was during the war years that Einstein introduced his theory of general relativity, more radical than his special relativity. As discussed in the introduction, since the time of the ancient Greeks until well into the 20th century many scientists assumed that the universe was eternal. Under general relativity there is no ether or constant frame of reference, and gravity is reduced simply to an effect of curving space-time. The general relativity theory replaces that most basic and intuitive of concepts from Enlightenment physics, Newtonian gravity, with the Einstein fi eld equation. May 11, 2014 - There's special relativity. As such, it provides the foundation of almost all of modern physics Your subtitle is “An intuitive introduction to Einstein's ideas, and why they matter,” and next year is the 100th anniversary of Einstein's 1915 publication of his general theory of relativity. It also turns out that no experiment can tell the difference between floating motionless in deep space and accelerating under the pull of gravity (when you fall you're weightless). Oct 11, 2010 - Einstein's Space-Time: An Introduction to Special and General Relativity is a textbook addressed to students in physics and other people interested in Relativity and a history of physics. Einstein's theory of general relativity is one of the crowning achievements of 20th century science. These equations predicted that the Universe would contract if gravity were too strong or expand if it were too weak. If they do that in a way that's not subject to the basic description of light, then we need a better field theory that includes electric and magnetic fields within the same bending of space-time as general relativity. Introducing MIT Technology Review Insider. Special relativity had considered only constantly moving reference frames, so a .. Mar 1, 2014 - The reason it comes up in these contexts is that the theory of relativity represents our current understanding of the nature of space, time, and gravity. Einstein's stunning insight (paraphrased) was “dudes! Jun 4, 2013 - A decade after his paper on special relativity, Einstein published his general relativity that addressed accelerated reference frames and provided a new theory of gravity.
