The first edition of this textbook was dedicated to our sons, Michael, David, and Jonathan, who not only helped with some of the artwork but who were also exceptional in their ability to educate and entertain themselves during the multitude of hours we spent away from them while writing this book. They are now grown men and clearly benefited from their experience. The second edition is dedicated to our cute and brilliant granddaughter, Margaret Debily, whom we fondly call Maggie. Thanks and love from Mimi and GD.

I would like to dedicate this textbook to my daughters, Kaleigh and Chloe. I love you both so much. Thank you to my husband, John, for making all my dreams come true. In addition, I would like to thank all my friends and family for their support throughout the years.
