The Astronomy Class.
Have you been in a planetarium lately? I hate to say it, but I think it was Mr. Bailey's 7th grade science class when I last visited our local planetarium. I've been to the lobby to pick up star charts and posters, but until Monday night I had not ventured into the labyrinthine halls that lead to the main chamber in...well, in a good many years.

Little had changed. Oh, I'm sure lots of the technology has changed. There was still that same hushed quiet feeling as we sat in a mauvish sunset waiting for the instructor to introduce himself. There was the eye adjustment as the sunset faded and the night sky appeared. And there was that reckless vertigo as we spun from north to south.

Then I got to thinking. Who invented the first planetarium? So I'm off to google land. Later!

Whoa! That was quick. 1923...it's all here.
