Why Do We Measure?

“We don’t know what we don’t know.

If we cannot express what we know in numbers,we don’t know much about it.

If we don’t know much about it, we cannot controlit.

If we cannot control it, we are at the mercy ofchance.”

Mikel Harry

“If we cannot express what we know in terms of numbers then ourknowledge is of a meager and unsatisfactory kind.”

Lord Kelvin
