WK: Most numerical computation doesn’t matter. I know that sounds perverse, but in my experience, looking over the shoulders of other people, at least nine-tenths of what they compute gets thrown away, much of it without ever being looked at. They have only to get a glimpse of something to realize they never should have computed it in the first place.
