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).
