An physicist, a mathematician, and a metrologist are all given the task of determining the volume of a little red ball.

The physicist says "This is too easy..." and fills a graduated cylinder with water, places the ball in the water, measures the displaced volume and reports the volume of the ball.

The mathematician responds "It's even easier than that," and derives an equation for the volume of a sphere as a function of its diameter, measure the diameter, and calculates the volume.

The metrologist laughs and says "I've got you both beat" and pulls out a table of volumes of little red balls.
