careful reading of an early draft of this book, and for contributing many useful
and incisive comments. Robert Burckel, in his unbeatable style, studied
every word that I wrote and corrected them accurately and mercifully. David
Collins painstakingly taught me the chapter and verse of the Chicago Manual
of Style (or CMS), and many other truths about language and accuracy as
well. Ed Dunne, as always, was an encouraging and dynamic editor. He
read several drafts of the book and contributed decisively to its form and
structure. Ed also engaged ﬁve excellent reviewers who contributed incisive
criticisms and suggestions that have certainly made the book tighter and
more on point.
Mathematics is a highly varied, rich, and rewarding life. Welcome to it.
I hope that you spend a very pleasant and productive thirty or forty years
making your way through the profession, and that you ﬁnd many rewards
and comforts. May this book be your touchstone as you get started.
