I often say that when you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely, in your thoughts, advanced to the stage of science, whatever the matter may be.
Lord Kelvin (William Thomson) London 1883.
Measurement is where theory and practice meet. Science, engineering and industry would have little use for mathematics or arithmetic were it not for measurement. Measurement provides a major component of the interface between theory and the real world.
