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.

Sir Charles Vernon Boys

Died 30 Mar 1944 at age 89 (born 15 Mar 1855).English physicist and inventor of sensitive instruments. His studies included in mining, metallurgy, chemistry and physics. He was also self-taught in a wide knowledge of geometrical methods. In 1881, he invented the integraph, a machine for drawing the antiderivative of a function. Boys is known particularly for his definitive book (1890) on the physics soap bubbles. He employed the torsion of quartz fibres to measure minute forces, repeating (1895) Henry Cavendish's experiment, to improve the measurement of the Newtonian gravitational constant. He also invented an improved automatic recording calorimeter for testing city coal gas (1905) and high-speed cameras to photograph rapidly moving objects, such as bullets and lightning discharges. He was knighted in 1935. Upon retirement in 1939, he grew and studied garden weeds.«
