For middle-aged nerds like me, one of the great defining works of twentieth-century literature is, of course, Hitchhiker’s guide to the Galaxy.
If you haven’t heard of it, then either you’re too young, too old, or you’re the sort of person who relies on other people to fix your computer. Either way it doesn’t matter. For now, all you need to know is that it was a popular book and TV series about 30 years ago in the comedy Science-Fiction genre. A true nerd can quote it chapter and verse, like the Bible.
