The Trisectors, by Underwood Dudley Twenty Years Before the Blackboard, by Michael Stueben with Diane Sandford The Words of Mathematics, by Steven Schwartzman Preface FOR WHOM IS THIS BOOK INTENDED? This book shows that there are very few degrees of separation between mathematics and topics that provoke good conversation such as, why language matters, how we know what we know, the value of fame, the objectivity of truth, when fiction trumps truth, the inevitability of progress, the anatomy of thought, and the limits of reason. Therefore, if you enjoy good conversation, whether you are a mathematician or otherwise, this book is for you. How To Use This Book To locate a Conversation Starter or item, you can a. Drop the book on the table, see where it opens, choose an item (indicated by num- bers in square brackets, for example, item [212]), and start from there. Repeat if desired. b. Consult the Table of Contents or the Index and choose any item. c. Read the book in the standard way—linearly. Start from page 1 and go on from there. d. Go to the section “Sampler,” on page 1, and choose themes and supporting items presented there. ACKNOWLEDGEMENTS This work is rooted in Mathematical Maxims and Minims, a collection of quotes published by John de Pillis and Nick J. Rose in 1988. Many have given of their good time and efforts toward this work.

Although given the option of refusal, all contributors of original quotes were gra- cious in their willingness to share their space with my cartoons, all of which are original for this book. For their kindness and good sportsmanship, my deepest grat- itude. No book assembles itself—it takes hours of effort by editors and produc- tion people. Therefore, I wish to express my appreciation of the professionalism of Elaine Pedreira and Beverly Ruedi of the Mathematical Association of Amer- ica. And what pleasure it was to work with Professor Gerald Alexanderson whose editorial skill and sound judgment enhanced this work immeasurably. And to my wife, Susie, our three daughters, Emmeline (University of Hawaii, Hilo), Gretchen,
