Reynald's number
I know my explanations grate on those who like the text book language and the use of charts and graphs and the use of engineering jargon.
But - I have found out - the hard way - that explaining technical points can be a real exercize. The proof in an explanation is that the person to whom the explaination is proffered -- does understand .
At least well enough to feel their question was answered.
To clarify:
If you can't explain it in layman terms - y-you really do not thoroughly understand it.
