In physical science a first essential step in the direction of learning any subject is to find principles of numerical reckoning and practicable methods for 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 measure it, 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, whatever the matter may be.
What you measure affects what you do. If you don't measure the right thing, you don't do the right thing.
Measure what is measurable, and make measurable what is not so.
See {611311} for a later similar view.
Progress is made where progress is measured.
We turn to quantities when we can't compare the qualities of things.
Time is a measure of space, just as a range-finder is a measure of space, but measuring locks us into the place we measure.
I belong to those theoreticians who know by direct observation what it means to make a measurement. Methinks it were better if there were more of them.
A gramme is better than a damn.
I know it was more than that. But it was also less than that, too.
I was...labelled as an advocate because...I measured something.
I want to talk about things that are quantifiable, not a bunch of metro riders and crowd sizes.
Commercialism that has absolutely no relationship to quality whatsoever, only quantitative assessment of a thing.
There is no shortage of mechanisms by which to measure almost anything.
I can just remember games as a young player, counting my stats on the sideline. 'What am I now? I'm this many completions for this many attempts. I wonder what my rating is.'
I don't read my reviews, I measure them.
Through and through the world is infested with quantity: To talk sense is to talk quantities. It is no use saying the nation is large. . . . How large? It is no use saying the radium is scarce. . . . How scarce? You cannot evade quantity. You may fly to poetry and music, and quantity and number will face you in your rhythms and your octaves.
The exact Quantity and Quality being found out, is to be kept to constantly.
If someone separated the art of counting and measuring and weighing from all the other arts, what was left of each (of the others) would be, so to speak, insignificant.
