No need to make measurements. If you are unable to make a simple

AND THEN, quoting Lord Kelvin:

"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."
