Dear All,

Is science true? Yes, that is the question. Is it really, really true? Helping to motivate this discussion, we recently assailed upon a little philosophy of math, here, where we remarked and marveled how math can represent both real and non-real things and yet both kinds can teach us about reality.

I thought this was incredible, and so it is! However, I used the Navier-Stokes equations in fluid mechanics as an example and as one commenter stated, even the respected Navier-Stokes equations aren’t **true** in the hard sense…they neglect many things like radioactive decay. This did not sit well with me, for I like to think what I am doing is true, and caused me to wonder what is truth, and what in science matches this. Let’s combine this discussion with a little science history.
