A note on the use of these PowerPoint slides:
We’re making these slides freely available to all (faculty, students,
readers). They’re in PowerPoint form so you see the animations; and
can add, modify, and delete slides (including this one) and slide content
to suit your needs. They obviously represent a lot of work on our part.
In return for use, we only ask the following:
If you use these slides (e.g., in a class) that you mention their
source (after all, we’d like people to use our book!)
If you post any slides on a www site, that you note that they are
adapted from (or perhaps identical to) our slides, and note our
copyright of this material.
