Einstein himself explains his then controversial Theory of Relativity and discusses its most recent developments as of 1921. The lectures included here are "Space and Time in Pre-Relativity Physics," "The Theory of Special Relativity," and "The General Theory of Relativity" (in two parts).
This was Einstein's first book to be published by an American publisher.
These were Princeton's Stafford Little Lectures for 1921 and were delivered just 5 years after Einstein published his comprehensive paper on general relativity. It would be over a decade before he left Europe permanently and joined the Institute for Advanced Study at Princeton.
August 15, 1923 issue of Hanovia Technique and Information Service is laid in. Includes information on ultraviolet and quartz light therapies.
