Finally! I've started book 1 of the principia!
Well, the first 11 lemmas showed me that my geometry is VERY rusty...as in I needed to look up term like subtense/subtend, and other terms.
I find no better place to figure thing out that to read as close to the original works of those whom you want to understand. They are working out things for the first time and it is interesting to see how the do it. Euler is another you might find interesting, along with Leibnitz.
I am also looking into Aryabhata, the famous astronomer from India...
We will expect a book report! ?
Yeah, 'cause I'm not readin it.

Posted by starwatcher-alI missed the early phases of the eclipse but the clouds mostly left during totality. All in all a great eclipse. Next one is Nov. 8-22

Posted by starwatcher-alOne of these days I think that I'll figure out this Nikon.
