Acknowledgements
While the cover of this textbook lists only two names, the book as it stands today would simply
not exist if not for the tireless work and dedication of several people. First and foremost, we wish
to thank our families for their patience and support during the creative process. We would also
like to thank our students - the sole inspiration for the work. Among our colleagues, we wish to
thank Rich Basich, Bill Previts, and Irina Lomonosov, who not only were early adopters of the
textbook, but also contributed materials to the project. Special thanks go to Katie Cimperman,
Terry Dykstra, Frank LeMay, and Rich Hagen who provided valuable feedback from the classroom.
Thanks also to David Stumpf, Ivana Gorgievska, Jorge Gerszonowicz, Kathryn Arocho, Heather
Bubnick, and Florin Muscutariu for their unwaivering support (and sometimes defense) of the
book. From outside the classroom, we wish to thank Don Anthan and Ken White, who designed
the electric circuit applications used in the text, as well as Drs. Wendy Marley and Marcia Ballinger
for the Lorain CCC enrollment data used in the text. The authors are also indebted to the good
folks at our schools’ bookstores, Gwen Sevtis (Lakeland CC) and Chris Callahan (Lorain CCC),
for working with us to get printed copies to the students as inexpensively as possible. We would
also like to thank Lakeland folks Jeri Dickinson, Mary Ann Blakeley, Jessica Novak, and Corrie
Bergeron for their enthusiasm and promotion of the project. The administrations at both schools
have also been very supportive of the project, so from Lakeland, we wish to thank Dr. Morris W.
Beverage, Jr., President, Dr. Fred Law, Provost, Deans Don Anthan and Dr. Steve Oluic, and the
Board of Trustees. From Lorain County Community College, we wish to thank Dr. Roy A. Church,
Dr. Karen Wells, and the Board of Trustees. From the Ohio Board of Regents, we wish to thank
former Chancellor Eric Fingerhut, Darlene McCoy, Associate Vice Chancellor of Affordability and
Efficiency, and Kelly Bernard. From OhioLINK, we wish to thank Steve Acker, John Magill, and
Stacy Brannan. We also wish to thank the good folks at WebAssign, most notably Chris Hall,
COO, and Joel Hollenbeck (former VP of Sales.) Last, but certainly not least, we wish to thank
all the folks who have contacted us over the interwebs, most notably Dimitri Moonen and Joel
Wordsworth, who gave us great feedback, and Antonio Olivares who helped debug the source code.
