The most fervent thanks are due to my wife, Jennifer Cornish, who put up with my focusing too much on this book while she was finishing up her doctoral dissertation.
Thanks to Jon Phillips, Michael Ivancic, Aubrey Keus, and Scott Bliss for helpful comments. Jon Phillips in particular gave very useful technical advice in the early stages of writing, and I think of him as the unofficial early tech reviewer. Thanks are obviously also due to the official tech reviewer Pat Eyler, whose influence made this is a much better book than it would otherwise have been.
Thanks as well to professors Richard Dawkins of Oxford University and Brendan McKay of the Australian National University for their cooperation in my referencing their work.
