Need something to read on a Sunday? The story of Codes and Codebreakers in World War I is an interesting little chapter which is still less-known than the famous codebreaking effort of WWII. Maybe you're intrigued and want to read the whole online book, Codes, Ciphers and Codebreaking, or, if codes aren't your thing, maybe A History of the Telescope or Missions to the Planets or Elementary Chemistry or any of the other on Greg Goebel's Vectors site - dedicated to educational writings on science, technology, and history.
