Wow this thread has really taken off, 2 pages already and it was only posted yesterday. Wonder if it’s due to Bernoulli, Kutta, Joukowski, or simply the Magnus effect. Coanda was discussed earlier.
That’s all, nothing useful
Oh, one more thing as G the E said, engineers, and scientists deal with probabilities and not certainties, or more precisely they do not deal with 100% probabilities. These theories you all are discussing on the thread were borne from consensus. Bunch of researchers sat around in a conference and said, yeah that sounds reasonable; the math and research supports the model, we’ll adopt it. Except it is not quite so clean and tidy; politics and personal egos always get involved. Clearly certainties can be part of engineering and the sciences, but only when it is defined as a probability as in p>.0001 or some such nonsense. A measure of conviction is required for prudent action, whether you call that a certainty or a p value. Anyway carry on, it's most entertaining.
