Computational software used by developers of airplanes do not seem to allow simulation of the dynamics of stall and so the impact of stall on aircraft design and safety assessment must be done solely by expensive and time-consuming experiments in flight, and then also the design of the apparentl...
How do airplanes stay in the air? Why is water wet? What makes a rainbow? Why don't birds get electrocuted when they land on an electric wire? Is water actually tasteless? Pure water is practically colorless, odorless, and tasteless. But it's not at all simple and plain and it is vi...
