As we agreed on in class last week, I am canceling this class so that we can see the solar eclipse. Our classmate, Sherelyn Alejandro, who will start a PhD in astronomy in the Fall, is hosting a viewing event in Central Park, in Sheep's Meadow, from 12–4. The actual eclipse itself will begin at 2pm and peak at around 3pm. I (professor Harris) will be there, and I'll bring some extra glasses. You are all welcome to join as well, but attendance is not required. I have adjusted the later readings.
