Why you shouldn't teach your kids Physics...

From a Calvin and Hobbes comic strip...
Dad: Playing a record? I'll show you something interesting. Compare a point on the label with a point on the record's outer edge. They both make a completed circle in the same amount of time, right?
Calvin: Yeah...
Dad: But the point on the record's edge has to make a bigger circle in the same time, so it goes faster. See, two points at two speeds even though they both make the same revolutions per minute!
Calvin:______
