Note
I mowed the lawn after work. Nice to get it done.
I read the AP thread about mapping desert as white or yellow. It reminded me of something Bill James wrote a couple of days ago. He drew a distinction between "literal meaning" and "actual understanding." Literal meaning looks at the standards and sees one definition and that's that. Actual understanding is comfortable with developing ideas and ways of thinking - recognizing the limits of the standards and that things are always improving.
I think that's a bit like the discussion on AP. The literal meaning is that desert must be yellow. The actual understanding is that if white works for the desert, that's fine.
The literal meaning orienteer running in Greenland would be confused. They'd stand in the start triangle trying to figure out where they were because even though the buildings, trails and roads fit, the map was white and there isn't a forest. The actual understanding orienteer would look at the map and start navigating, knowing that the mapper just didn't bother drawing yellow over the entire map.
