An unnamed girl in an unnamed, but contemporary, European city enters a rather gloomy old building, reading its address from a crumpled piece of paper. Inside, being given preference over a dozen people sitting in a waiting room, she is ushered into the office of Albert Einstein. "You said that time doesn't exist, so I took the liberty of coming to see you," she says. "You did the right thing," he replies. Thus a conversation ensues that spans all the 176 pages of this book.

This is a new edition of an old classic. Abbott wrote this beautiful tale over a hundred years ago under the pseudonym A Square. It still is one of the best introductions to a mathematical world of higher dimensions, and it's an amazingly imaginative social satire, too.
Teaching a machine to understand music is an incredibly difficult task, which uses all the mathematical power of digital signal processing. But teaching a machine to compose music is quite another matter, and the wonderful world of mathematical patterns proves to be a gold mine. Nick Collins talks to Plus about his artificial musician.
