First post 2

I am getting ready to upload recent edits to Volume 1 and Volume 2 to the publisher. Many minor corrections plus some filler pages with autobiographies of famous astronomers.  I tried to pick a good variety.  

I also fixed a nagging problem with a puzzle about the models of the universe which had Kepler’s 3rd law quoted incorrectly.  It’s fixed now.

My next project is to revisit and edit the powerpoints.  

Also, I will be adding activities to this blog as I make new things and try out stuff in workshops.
