Subject: Terminator
I have a site on my browser, www.mapmaker.com/shadowfacts/sunweb.asp
that shows the terminator throughout the year. It is fascinating to see
how rapidly the shape changes, and I was astonished to see this evening
that it is nearly a straight line, as we approach the equinox.
Of course, a little thought shows that I have should have expected this,
but to see it on a 'flat earth' reminds one of what is happening to a
globe, or the earth itself.
I expect others have more fun with other representations!
Doug
