Writing these columns often requires a considerable amount of reading and then thinking—both alone and always out loud to my wife as I try to explain to both of us what I have been reading. To be honest, this column reminded me of what I used to jokingly say to my planetarium audience: “This program will be over your head!” And in a way this column is similarly up there and is guaranteed to change your level of confusion. But isn’t that what we do with our students—not confuse them, but challenge any preconceptions they might have by thinking both in and out of the box?
