The Meaning of Relativity by Albert Einstein
Publisher: Princeton University Press 1922
ISBN/ASIN: B006BASIFC
Number of pages: 134
A condensed unified presentation intended for one who has already gone through a standard text and digested the mechanics of tensor theory and the physical basis of relativity. Einstein's little book then serves as an excellent tying-together of loose ends and as a broad survey of the subject.
