Tonight I’ll be giving the Mid Hudson Astronomical Association talk on the basics of celestial mechanics, and what I figured out to make my Where is Io application.  The talk picked up the poetic “Tracking the Movement of the Heavens” title somewhere along it’s development.

This is going to be a tough talk, given how varied our audience tends to be, but I’m hoping that I’ve got enough hooks to get people in early, and plenty of meat for people that want to know more. The practice run through after work last night went quite well, the narrative turned out to be stronger than I realized, and I got some good feedback that definitely makes this a better presentation.  Thanks to Mike, Jeremy, and Sean for that.
