Konstantin Eduardovich Tsiolkovsky was born in Russia in 1857. The fifth of eighteen children, Tsiolkovsky first imagined a place without gravity when he was 8. It was a small hydrogen-filled ballon that rose to the ceiling each time he let it go that excited his imagination. Tsiolkovsky’s mother taught him to read and write. Before […]
Russian Rocketman Konstantin Eduardovich Tsiolkovsky, truly a “Citizen of the Universe,” introduced these Sixteen Stages of Space Exploration in 1926. He believed that these incremental steps would bring man into space and allow him to thrive: Design of rocket-propelled airplanes with wings. Progressively increasing the speeds and altitudes reached with these airplanes.
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.
Yesterday I had the opportunity to meet with Dr. John Anderson, Curator of Aerodynamics at the National Air & Space Museum. Dr. Anderson was kind enough to give me a walk-through on the workings of the balances used by the Wright brothers in their wind tunnel. He was thorough and patient in his explanation, stopping […]
Nine inches in circumference. Weighing in at about five ounces. Made of cork wound with woolen yarn covered with two layers of cowhide stitched by hand precisely two hundred sixteen times… Every baseball used in Major League play today is made to these specs. Over the years there have been claims of juicing, concerns about […]
