Living on a Sphere

If the earth were flat, she would be half as much fun. The grassy slope would always have the same orientation to the sun, for one thing. With a tilted earth, sometimes it faces the sun directly and sometimes it’s almost flat and the sun flashes over it like a wind, barely rustling the tips of its grasses.

And what about that cliff, eh! Because this spherical earth is spinning on its axis, sometimes during a day it faces the sun directly, and sometimes is in various degrees of shadow or illumination. The edges between these effects create the wind, or the tension between gravity (our point of view) and wind (our other point of view) that we live in. How cool is that!
