Online Class Lesson and Communication News

UPDATE - May 26 at 1:58 AM: I have sent out e-mails with grades to everyone who completed the course. Have a great summer, read lots of interesting non-fiction stuff, and stay healthy.

UPDATE - May 22 at 2:34 AM: I took a break from grading finals (that will take me several more days) to add pictures of our COVID-19 Victory Garden. It is shown at our COVID-19 Social Isolation Garden below older pictures of the garden in its early glory days. To be sure, my wife is the gardener. She worked in a hydroponic garden for a few years where the other workers called her the "Queen of Green" and made a crown for her.

Note: I have stashed old UPDATES in a new subdirectory at
