A mathematician, a physicist, and an engineer were each given the same red rubber ball and told to find the volume.
The mathematician carefully measured the diameter
and evaluated a triple integral.
The physicist filled a beaker with water, put the ball in the water,
and measured the total displacement.
The engineer looked up the model and serial numbers in his red- rubber-ball table.
