I recollect at ATPL groundschool this whole thing came up. Sat in our class was a smart-a*** who happened to be an Airbus engineer from Toulouse. He queried why we weren't being taught about the Reynold's Number (whatever that is). Without breaking his stride, our very knowledgeable instructor who had survived 40 years or so of flying without killing himself came back with the following:
"Look lad, if you want to stay an engineer, keep talking about irrelevant numbers. If you want to be a pilot, just learn that you can only pull the stick back so far before things go wrong."
