Mathematics physics chemistry engineering
A mathematician, a physicist, and an engineer were all given a 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. If it was my company: The engineer tried to look up the model and serial numbers, couldn't find them, so told his manager that it's just not going to work.
We chemists, who test by destroying a small sample, would weigh the ball, snip out a 1mm cube and weigh this - thus getting an accurate volume.
