How Stuff Works is a brilliantly geeky site that covers a huge range of topics and explains them in minute detail and in plain English, everything from the humble telephone to a 16-part article on how to program in C.
The work of one man, the aptly named Mr Brain, How Stuff Works also includes an archive of answered questions. A free newsletter gives you details of additions each month - the latest features How Caffeine Works, How Cells Work, How NATO Works, and How Chess Computers Work, as well as answers to topical questions such as "What is an MP3 file and how does it work?" and "Will cars start on 1 January, 2000?" One cheeky visitor asks: "Is your name really Marshall Brain, or did you make that name up?"
