Please use this address to notify me of typographical errors and of suggestions for improvement in diction. I strive to express every concept as clearly as possible, so if you think that I could improve some expression or explanation, please let me know. Improvements will appear in a subsequent version, and if warranted, I'll post an improvement under a revisions menu for use by current readers.
