IN your schooldays most of you who read this book made acquaintance with the noble building of Euclid's geometry, and you remember-perhaps with more respect than love-the magnificent structure, on the lofty staircase of which you were chased about for uncounted hours by conscientious teachers...
Description
After completing the final version of his general theory of relativity in November 1915, Albert Einstein wrote a book about relativity for a popular audience. His intention was 'to give an exact insight into the theory of relativity to 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 of theoretical physics.' The book remains one of the most lucid explanations of the special and general theories ever written. In the early 1920s alone, it was translated into ten languages, and fifteen editions in the original German appeared over the course of Einstein's lifetime. The theory of relativity enriched physics and astronomy during the 20th century.
