I’ve discovered that exercises are exceptionally useful during a seminar to complete a student’s understanding, so you’ll find a set at the end of each chapter. The number of exercises has been greatly increased over the number in the first edition.

Many of the exercises are fairly simple so that they can be finished in a reasonable amount of time in a classroom situation or lab section while the instructor observes, making sure all students are absorbing the material. Some exercises are a bit more challenging to keep advanced students entertained. The bulk of the exercises are designed to be solved in a short time and are intended only to test and polish your knowledge rather than present major challenges (presumably, you’ll find those on your own – or more likely, they’ll find you).
