"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 state of Science, whatever the matter may be." --Lord Kelvin | [reply] |
I wonder if he could express that sentiment in numbers? And if he couldn't, would that mean he didn't know what he was talking about?
