A long but very interesting, and educational, read.
It reminded me of a small sidebar on a page in FATHOM, a publication of the US Naval Safety Center, back in the 1970s. It was titled “Rules of Thumb and Ballpark Estimates” and contained these two bits that I have never forgotten.
“It is better to solve a problem with a crude approximation and know the truth, plus or minus ten percent, than to demand an exact solution and never know the truth at all”.
“An easily understood, workable falsehood is more useful than a complex, incomprehensible truth”.
