Ball Bearings

Animation of Ball Bearing

A mathematician, a physicist and an engineer were being interviewed. As part of the process, they were given 2 brass ball bearings, left alone for a while, then asked what they had done.

  • Mathematician: “I haven’t done anything with them, but I’ve some theories about 2-ness.”
  • Physicist: “I’ve tried to balance one on the other, and have some ideas about friction.”
  • Engineer: “Er… they broke.”
