Today is a Pythagorean Day because 8 15 and 17 form a Pythagorean Triple. Has there ever been a solar eclipse on a Pythagorean Day? I'm watching it on tv because I need my eyes and I saw the one in 1979 and it wasn't that big a deal. Just another chance to verify Einstein's Theory of Gravity and to sell smoked glass.
@MeasurementBlues: I read the other day about fake eclipse glasses starting to appear online....
I heard that too -- if you look at an incancecent or flurescent light through them and you can see any light, don;t use them to view the eclipse -- even 1% of the sun's light is enough to cause retinal scarring
Thank you for the suggestion! I'll have to give that a try. I'm in the SF Bay Area so I should get 0.8 magnitude around 10:15 AM PDT according to greatamericaneclipse.com. Now I have a week to find a suitable wall. There's a great one next door, but only for mid-to-late afternoon.
I'll look on campus. Good opportunity to impress undergraduates :-)
