I should be hawking my own books, but I couldn't resist posting this when it arrived in the mail today. [Agnes Penny is my youngest sister, and yes the picture is of her wonderful family.] The book is available from TAN Books.
Sinner, husband (don't they go together?) and father of .... well, counting. Also patent agent, physics instructor, homesteader, sometimes writer, ex-quail farm hand, ex-paper boy, ex-publisher, ex-editor, ex-research engineer, and ... well you get the picture.
I am available to speak for large and small fees on just about any topic, especially those I am interested in.
