John Baez has promised to write a witty, enticing, entertaining, and
informative preface for these notes, but he hasn't gotten around to it
yet. So I'll just say that they start with the question, "What
the heck is a photon, anyway?", and go on from there. For
more, see the Introduction.
The notes are divided into two parts. Part I is available in both HTML and postscript format; part II is available only in postscript at present. (The postscript for part I has much nicer typesetting than the HTML, but no figures). There is also a Unix tarfile containing all the HTML and GIF files. If you place the tarfile in directory foo and untar it there, it will create a subdirectory schmoton and put all the files there.
I tried converting these notes from LaTeX into HTML using latex2html, but I had problems, so the version you see is something of a compromise.List of Figures:
