Blackbody Physlet
I’m supposed to keep on top of these things, and I’ve certainly read about them enough, but usually in passing and I immediately rush off to the next thing on my "to-do" list. What am I mumbling about?

Sunset is not until nearly 7:15 pm, and it won’t be truly dark (well, as dark as it gets in NYC) until after 8:30 pm, but we’ll start shortly after 8:00 pm with views of the first quarter moon and, as it gets a bit darker, views of Saturn and it’s rings.

I decided to do a quick test of …
