Math is a fantastic tool to get you in the ballpark! Of course no engineer would go for minimum spec, if you need 500N of lift to fly, the engineer wants 5, 000N if within reason. Again pointing to the beauty of math, if the math is good enough to get you in the ballpark one way, it must be good enough to get you in the ballpark if you're going above and beyond as well. Philosophically, we see often that new equations and techniques are needed in order to go above and beyond, because the ones we rely on to get us to point A, may work at point B, and C, but don't necessarily encompass enough to get us to point F. Sometimes what you need to get to point F doesn't exist, or more often, the solution is found in another set of equations and points of view.

Maxwell's laws for instance apply very nicely to Aerodynamics, then combining that with Newton's laws, and Bernouli, and, Prandtl, and Hawksworth, and Boltzmann, et al. All these methods of getting to more or less where you need to be. You have something guiding a feedback loop where you experiment, see where your understanding is right, where it's wrong, where it matches with theory, where theory breaks down. Then refining your methods and re-testing, so on and so forth.

Great video, but do you do if you don't ha e a wind tunnel or the lift force when calculating CL
