To my grandfather, Benjamin Klein.

To all of my teachers and collaborators,
especially those whose voices echo
in the pages of this book.

– Jason Osder

To my parents, John and Marcia,
for supporting me in my dream to do what I do.

To my beautiful wife, Catherine.
Without her love and support, this book
would not have been possible.

Finally, to John Woody, my mentor,
who showed me the power and beauty
of teaching and learning.
