First, I would also like to acknowledge the efforts of the production team behind this book. These folks were the glue thatkept everything together. Thanks to Timothy Green for giving me the opportunity to write this book. I appreciate yourconfidence in me! Thanks to Jennifer Housh for managing the development process. No matter the time of day, Jenni wasalways there with the information I needed. Thanks, Jenni!

Finally, a huge thank you to Brian Barber. Brian reviewed each and every word and exercise step in this book for technicalaccuracy. His efforts kept me honest and were absolutely invaluable, dramatically increasing the overall quality of this title.Brian spent many late nights testing the lab exercises in this book, ensuring that you have a successful experience.Thanks, Brian!
