Yes, fix mistakes. Not cover them up with froo froo mathematical models with no observational backing in the real world.-All models are wrong, but some are useful. George EP Box.-That is one of the points of building models so that we can test them. Just think we would never do anything if we did not build models, mathematical or physical.-It's OK to be skeptical of froo froo models - but before discarding them what is your observational evidence that they don't fit?-We built the first aircraft (model or otherwise) to see if we could fly. If these froo froo models don't fit the existing observational data then no one is going to buy into them anyway.->Matt - how do we pronounce "scepter?" The same way we pronounce "sceptre"?
