methods of measuring some quality connected with it.

21 W E M E A S U R E! In physical science a first essential step in the direction of learning any subject is to find principles of numerical reckoning and practicable methods of measuring some quality connected with it. 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 meagre and unsatisfactory kind: it may be the beginning of knowledge, but you have scarcely, in your thoughts advanced to the stage of science. --William Thomson, Lord Kelvin,
