by Eric J. Chaisson
New York: W. W. Norton & Company, 1990. 254 pages.

Written by an astrophysicist for general readers, Relatively Speaking explains the special and general theories of relativity and what they imply about the origins and structure of the universe. "An authoritative, gracefully written synopsis of modern relativity theory that should be accessible to a wide audience", writes Frank Wilczek.
