I looked at your profile after reading your post here.

The name Da Vinci is meaningless, you might consider citing Leonardo.

I actually did take a course in Astronomy once upon a time.

The Ptolemaic solution was found wanting just as were the works of Brahe, Newton, Galileo, and a host of others.

I took that course as sort of a lark. I never considered that I'd have to do real work by taking such a class.

I leaned a lot that year, and I'd advise anyone to take a university course in astronomy if they really want to learn a few new things.

Ptolemy gets a bad rap, but he was fairly accomplished in science. He knew the earth is round, which a lot of heavy thinkers after him did not. His reductions of astronomical data were good and sufficed for many centuries. Way ahead of his times.
