or I should say, 'the complete truth'.

I have a cousin that's Dean of one of the highest rated engineering colleges in the USA, (in fact he founded it).... he and I spoke somewhat recently and when I asked him about 'calculus' he explained it to me in a manner that showed 'answers' were in actuality 'estimations'. Estimations that are so close to precise that functionally you can use them without fear of significant 'error'... but 'estimations' none the less.

I won't even ATTEMPT to say here than I understand that fully... but it certainly intrigued me.

As an example... we know "Newton's Laws" to be in error...we know that for a fact... never the less his laws CAN be used, (for example in space flight), because the 'errors', (which ARE present), are so insignificant as to be non-factors.

Anyway... just a thought. - JamesJM
