Thank you to my wife, Cheryl, and my children, Theo and Aria, for allowing Daddy to toil, peacefully, in the basement, alone, to complete this work.

Also I would like to thank my Cass Technical High School teachers Mr. Max Green and Mr. Walter Downs, a Tuskegee Airman who felled 6 enemy aircraft in WWII, for giving me my serious fun teaching style.

Dr. David Doc Green and Dr. Duane McKeachie of Kettering University showed me how to simplify difficult concepts for students.

Dr. Larry Stark and Dr. Masayoshi Tomizuka of the University of California at Berkeley introduced me to UNIX, which has taken me further than I imagined.
