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.

Centrifugal creamer

In 1881, a centrifugal separator, was patented by Edwin J. Houston and Elihu Thomson (No. 239,659). A vessel spins inside a case that receives the lighter components separated "by the action of centrifugal force," while heavier components drain through an opening in the same tubular shaft by which the vessel is rotated. The separating vessel is swelled at the bottom, such as the frustrum of a cone, and fitted with a horizontal deflecting plate a short distance above the bottom which extends to a short distance from the side. The liquid to be separated is supplied through a central feedtube, enabling continous operation. The patent suggested various uses, including separating milk and cream or clearing muddy water for paper making.
