The thing I had never heard before was the thing about "ages" (aeons) and the precession of the Earth. I mean, WOW, that "the ancients" were able to keep track of the sun for so long to at least notice the effect of the precession of the Earth. That kind of crap blows my mind. |
It's really difficult stuff. Just to figure out that the earth goes around the sun took dozens of very smart people many years of tedious and challenging observations. I'm reading Longitude right now, and it'll blow your mind how much work it takes to do what are now trivial things.
