Daniel Bernoulli’s (1700-1782) work is integral to the field of aerodynamics. It explains the way that air moves over a curved surface. As the air moves up and over the curved surface of an airplane wing, it must flow more quickly than the air moving in a straight path across the underside of the wing. The faster flow atop the wing results in less pressure over the top of the wing. This reduction in pressure on the top of the wing is offset by increased pressure upward from beneath the wing. The net result is what is known as lift. It is this lift that enables an airplane to fly, whales to stay afloat, and birds to take to the air.
