This book is a collection of creative pieces?poems, short stories, essays, play excerpts?that give shape to mathematical and scientific content. This book portrays by example how various people work creatively with ideas from mathematics and other sciences. Creative writing about the content of mathematics and science is rare, and creative writing about the activity of mathematical and scientific creation is even rarer. And yet, when it occurs, it can be extremely popular, as well known plays like Proof and Copenhagen and biographies like A Beautiful Mind and The Man Who Loved Only Numbers attest. What draws the public to these works? And why, given that something does, are there so few examples of literature that engages these themes? Mathematics and science are part of world culture, part of the human spirit, fit subjects for art of all kinds.
