How airplane wings defy gravity with air pressure
Airplane wings generate lift by making air move faster over their curved top, creating lower pressure above and higher pressure below, pushing the plane skyward.
Airplane wings use a clever trick of physics to fly: Bernoulli's principle. Air flowing over the curved top of a wing moves faster than the air underneath, creating lower pressure above and higher pressure below. This pressure difference pushes the wing upward, generating lift. Swiss mathematician Daniel Bernoulli first described this in 1738, a concept crucial for modern aviation. This principle, combined with the wing's angle, allows planes to carry billions of passengers annually. Even birds and insects use similar pressure differences, showing nature's genius long before human flight.
