Abstract

I often say when you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind. — Lord Kelvin

Let proportion be found not only in numbers and measures, but also in sounds, weights, times, and positions, and whatever force there is. — Leonardo da Vinci
