delivered NOVA talk

Delivered a NOVA presentation at York University. Stars, constellations, coordinate systems, etc. Small-ish crowd. Waited to 5 minutes after to begin. Lots of good questions, there seemed to be good general interest. But I ran late, unfortunately, and that meant I had to skip the Stellarium demo. More seriously, we had to cancel the observatory tour. I felt bad. Just not on my game today...
