Calvin and Hobbes Record Player - by Bill Watterson for June 05, 1990

Transcript:

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 complete 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 on one disk move at two speeds, even though they both make the same revolutions per minute!
