The book is unusual in having a very large number of solved problems. Frankly, if I were to teach from the book, I'd like to see more opportunity for students to figure out how to solve real problems given only the theory. This is good for student's future skills and as feedback on how well I'm teaching. The book is easy to read and understand for someone without a strong background — easy for me to say and I hope true for real students. The solved problems should be helpful to someone who is without an instructor, having trouble, or no longer remembers how to solve a problem. Using SI units is a mixed blessing (in the US) at it minimizes turning problems into units conversion exercises but it provides no practice in this essential skill.
