The Red Rubber Ball

Variant 1

A physicist, mathematician and engineer were asked to determine the volume of a red rubber ball.

The physicist filled a beaker with water, immersed the ball, caught the runoff and measured its volume.

The mathematician set up and solved an appropriate triple integral, then measured the diameter of the ball and plugged in the number.

The engineer looked around on his bookshelf, then asked,

"Has anyone got a red rubber ball volume table? I've only got the ones for blue and purple."


Variant 2

A physicist, mathematician and engineer were asked to determine the volume of a red rubber ball.

The mathematician set up and solved an appropriate triple integral, then measured the diameter of the ball and plugged in the number.

The physicist filled a beaker with water, immersed the ball, caught the runoff and measured its volume.

The engineer looked over at the physicist's messy desk and by now heavily waterlogged notebook, and said:

"You do of course realise that you made the unwarranted assumption that the ball is incompressible, don't you?"
