These notes are designed to allow instructors to make transparencies off them, and for browsing. Each page of the notes can be retrieved by clicking one of two entries. Clicking the x.y entry shows the page in a size convenient for viewing. Clicking the P entry shows the page in a larger size convenient for printing, using your browser's print command, so that the printed output can be photocopied onto a transparency conveniently.

I especially thank Jaroslaw Wilkiewicz for scanning in my 115 transparencies one by one and preparing my home page. I thank F. Ali and A. Negatu for some assistance with understanding HTML and preparing the indices. Finally, I thank Addison-Wesley (especially Paul Dzus) for permissions to include hand-reproduced figures from the HKP text. Notice that each page ends in an acknowledgment supplied by Addison-Wesley. Be sure to retain this acknowledgment on every printed page. As indicated there, you may print the online page but do not reproduce the printed page again.
