God's Equation: Einstein, Relativity, and the Expanding Universe by Amir D. AczelMy rating: 3 of 5 stars
The Einstein field equations (EFE; also known as "Einstein's equations") are the set of 10 equations in Albert Einstein's general theory of relativity that describes the fundamental interaction of gravitation as a result of spacetime being curved by matter and energy. The Einstein field equations (EFE) may be written in the form:
This is, basically, "God's Equation" here and the history of its development. As such, it is a biography of Einstein, including some very human revelation about Einstein's ability to use people and be self-promoting. The main scientific advancements in the prelude to the field equations are special and general relativity developed in fits and starts revealed in Einstein's notebooks against the backdrop of WW I emerging and challenges to using eclipses to get validation of gravitational theories.
