Tsiolkovsky: Sixteen Stages of Space Exploration

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.  

Did Jon Lester Cheat?

The truth of the matter is that surreptitiously altering the surface of the ball is sort of a time-worn tradition. Not a noble tradition, to be sure, but one that is viewed as much a part of the game of baseball as adjusting yourself or spitting tobacco juice.

Bernoulli Effect

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. […]

An Ocean of Air

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.

Amazing Day at Air and Space

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 […]

Aerodynamics of a Baseball in Flight

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 […]
