Wolfram|Alpha is a search engine that lets you ask questions in normal language instead of just using key words. It has the ability to work things out "on the fly", according to its British inventor, Dr Stephen Wolfram. If you ask it to compare the height of Mount Everest to the length of the Golden Gate Bridge, it will tell you.
