Leaving this one up for continuity and because of the nerdy comment discussion about real quantities — appreciate all the early support and feedback. Why do wings generate lift? The real answer involves vortices, circulation, and some beautiful physics that awful social media posts gloss over. Most explanations either give you the wrong answer (equal transit time), a circular answer (Bernoulli's equation without the "why"), or just show you what happens without explaining the mechanism. This video walks through the actual physics — from Navier-Stokes to potential flow to the circulation theory that actually predicts lift. We'll cover: Why the standard explanations fall short What D'Alembert's paradox tells us about perfect fluids How starting vortices and Kelvin's circulation theorem generate lift Why the Kutta condition emerges from conservation laws Where this model breaks down I include - fun (if you're into that sort of thing) interactive lift simulator: aeronauty.com/lift Play with foil shape, angle of attack, and see potential flow in real-time - and the effect of invoking the Kutta condition.
