Slightly more technical look at the four forces of flight.
Ueli Gegenschatz takes everything we know about aerodynamics and puts it all into a series of brilliant extreme sports experiences in the pursuit of his dream of human flight. You can view this video and think about lift, drag, thrust, and weight, but chances are you’ll be too busy wishing you were there with him! […]
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. […]
In 1644, Evangelista Toricelli wrote, “We live submerged at the bottom of an ocean of air.” We don’t fee the force of the pressure of this fluid any more than aquatic creatures feel the force of the water on all sides. Why? Because there is a uniformity of pressure in both cases; gravity exerts pressure on all sides.
