Query: Full of Errors.

This book was the required text when I took Bruce Katz for an electrical engineering class. He noted on the first day that the book was full of errors, and every day in class he seemed to find more things that were incorrect in the text. I was forced to drop the class, along with at least 50% of the rest of the students who took him, because it was very difficult, if not impossible, to learn from the book and solve the review problems at the end of each chapter.
