Theory of flight contains perhaps the best introduction to the general theory of stability, while the introduction to dynamics of incompressible fluids and the chapters on wing theory remain particularly valuable for their clarity of exposition and originality of thought. The resolution naturally led us to a new theory of. Above the wing, the circulatory flow adds to the overall speed of the air. Thus a wing generates lift because the air goes faster over the top creating a region of low pressure, and thus lift. His publication on aerial navigation in 1810, marked the beginning of the science of aerodynamics.
