A mathematician, a physicist...

A mathematician, a physicist, and an engineer are all given identical rubber balls and told to find the volume. They are given any tools they want, and have all the time they need.
The mathematician uses a measuring tape to record the circumference. He then divides by two times pi to get the radius, cubes that, multiplies by pi again, and then multiplies by four-thirds and thereby calculates the volume.
The physicist gets a bucket of water, places 1.000000 gallons of water in the bucket, drops in the ball and measures the displacement to six significant figures.
The engineer writes down the serial number of the ball and looks it up online.

US Weights and measures

In 1873, the American Metrological Society was formed in New York City to improve systems of weights, measures and money. Its activities eventually extended with a committee considering units of force and energy, and another concerned with the adoption of Standard Time for the U.S. On 30 Dec 1884, at the meeting of the American Metrological Society at Columbia College in New York City, Charles S. Peirce read a paper on the determination of gravity. He also participated in a discussion of the adequacy of the standards of weight and measure in the United States and pointed out some of the deficiencies in the current system. As a result of his revelations, the Society passed a resolution recommending the appointment of a committee to advise Congress on the need for establishing an efficient bureau of standards.[Image: Cover of the Proceedings of the American Metrological Society, Vol. 1.]
