Acknowledgements

This book did not appear from nowhere, and I’m grateful to the people who helped build it.

Thank you to Prof. Richard Klein for invaluable assistance in setting up the technical backend of this book.

Thank you to my colleagues, whose earlier notes and course materials for related courses this book draws on and builds upon.

And thank you, most of all, to my students — past and present — whose questions, suggestions, and sharp eyes for typos and errors have shaped this book far more than any single author could have.
