Abstract:
"I often say that when you can measure what you are speaking
about and express it in numbers, you know something about it;
when you cannot measure it, when you cannot express it in
numbers, your knowledge is of a meagre and unsatisfactory
kind."
The above statement was made by Lord Kelvin (1824-1907) about'''
hundred years ago and is reproduced as the main theme of the present
paper. The only qualification that should be made is that when Lord
Kelvin made the above statement he did not think that the philosophy he
expounded was specially appropriate to engineering manufacture. The
present paper will consider how this philosophy can b3 applied to
engineering manufacture only. ...[cont.]
