Reference: Einstein’s 1920 Book
This Book summarizes Albert Einstein’s RELATIVITY: THE SPECIAL AND GENERAL THEORY, originally published by Henry Holt and Company, New York (1920).
Einstein’s Special Theory of Relativity addresses the effect of the finiteness of the velocity of light on the space coordinates. A much more comprehensive General Theory of Relativity then explains gravity by postulating a four-dimensional continuum that has acquired the properties of extension and durability.
This book summarizes the original presentation above one section at a time. The summary contains Einstein’s ideas in their purity.
The summary is accompanied by comments, also one section at a time, that provide a new interpretation of Einstein’s ideas. This interpretation gradually builds up a model of the universe that makes Einstein’s theory of relativity easier to understand.
It is my hope that more people will get the pleasure of really understanding this brilliant theory of relativity that was completed by Einstein in 1915.
