Albert Einstein's "Relativity: The Special and the General Theory" (1920) is a cornerstone of modern physics. Einstein intended this book for 'those readers who, from a general scientific and philosophical point of view, are interested in the theory, but who are not conversant with the mathematical apparatus'. Indeed, within the vast literature on the philosophy of space and time, Einstein's "Relativity" shall remain an illuminable and intelligible exposition, highly quotable as one of the most lucid presentations of the subject matter and a launching pad for any further inquiry on the fascinating features of our universe.
