Last, but certainly not least, we often thank all of those around us and forget those closest to
us. The editors and staff at McGraw Hill Higher Education, Heather Ervolino, Jeni Mcatee,
and Beth Bettcher were constantly helpful, professional, and responsive to our needs. We
owe them a tremendous deal of gratitude. The book was typeset by Aptara using Adobe
InDesign and InMath. Special thanks are owed to Sadika Rehman and Vibhor Singh.
We want to close by stressing that we are particularly indebted to Ellen Emerson White,
who went beyond her ways to help us, and who often traveled back and forth during the
execution of this project. Ellen has been absolutely amazing. Without her involvement and
daily interactions, this effort would not have been possible. Thank you Ellen!
