I am a professor of physics at Nyack College. I teach physics, astronomy, and physical science.
Here is the link for my Astronomy course downloads.
My wife, Kim, and I have taught at Nyack College since January 2011. Before that my wife and I taught at Simpson University in Redding, CA. See the pages About Me and my CV (Curriculum Vitae) in the nav bar at right for more details.
