First published in 1922, this book represents the first attempt to popularise the more accessible aspects of Albert Einstein's general theory of relativity. Eschewing the mathematical components that put the theory beyond many people's grasp, the author employs metaphorical examples and thought experiments to convey the fundamental ideas.

Edwin Emery Slosson was an American magazine editor, author, journalist and chemist. He was the first head of Science Service, and a notable popularizer of science.
