Douglas Noel Adams was an English writer, humorist, and dramatist. He is best known as the author of The Hitchhiker's Guide to the Galaxy, which started life in 1978 as a BBC radio comedy before developing into a "trilogy" of five books that sold more than 15 million copies in his lifetime, a television series, several stage plays, comics, a computer game, and in 2005 a feature film. Adams's contribution to UK radio is commemorated in The Radio Academy's Hall of Fame.
Adams also wrote Dirk Gently's Holistic Detective Agency and The Long Dark Tea-Time of the Soul, and co-wrote The Meaning of Liff, Last Chance to See, and three stories for the television series Doctor Who. A posthumous collection of his work, including an unfinished novel, was published as The Salmon of Doubt in 2002.
Adams became known as an advocate for environmentalism and conservation, and also as a lover of fast cars, cameras, technological innovation, and the Apple Macintosh. He was a staunch atheist, famously imagining a sentient puddle who wakes up one morning and thinks, "This is an interesting world I find myself in—an interesting hole I find myself in—fits me rather neatly, doesn't it? In fact it fits me staggeringly well, must have been made to have me in it!" to demonstrate his view that the fine-tuned Universe argument for God was a fallacy. Biologist Richard Dawkins dedicated his book The God Delusion to Adams, writing on his death that "Science has lost a friend, literature has lost a luminary, the mountain gorilla and the black rhino have lost a gallant defender."
What to do if you find yourself stuck in a crack in the ground underneath a giant boulder you can't move, with no hope of rescue. Consider how lucky you are that life has been good to you so far. Alternatively, if life hasn't been good to you so far, which given your current circumstances seems more likely, consider how lucky you are that it won't be troubling you much longer.
It is known that there are an infinte number of worlds, simply because there is an infinite amount of space for them to be in. However, not every one of them is inhabited. Any finite number divided by infinity is as near nothing as makes no odds, so the average population of all the planets in the Universe can be said to be zero. From this it follows that the population of the whole Universe is also zero, and that any people you may meet from time to time are merely products of a deranged imagination.
