...Young's Modulus...
...many excellent players today. A good grip is like a solid hinge on an oak door." Sarazen goes back to hickory sticks that required shellacking in the rain, and is amused by the '80s fashion, which encompasses titanium shafts, tungsten fibers, beryllium-copper, manganese-bronze and high-modulus graphite. "Of course," he says, "the modern player thinks it's the equipment. You know that's baloney...
...taught by Associate Professor Erik Mollö-Christensen. First, Mollö-Christensen holds a lottery, and the number each student draws corresponds to something in the lab-a piece of wire, a piece of plastic tubing or of plywood. Working in pairs, the students are required to determine the modulus of elasticity of the material they drew. Two students, working with a piece of brass, determined its elasticity by measuring the speed at which sound passed along it. Explains Mollö-Christensen: "They can do it any way they want to-so long as they find out." On another project...
...near, Von Karman turned more and more to military design. As adviser to the U.S. Army Air Forces, he worked on jet engines, rocket motors, high-speed wind tunnels. Most of his work was theoretical. The principles that bear his name (e.g., the Karman Vortex Trail, the Karman double-modulus theory of columns) have no meaning for laymen (or for most airmen), but modern aerodynamics is based solidly on them...
Guarded deeply in a Paris cellar is a long platinum bar. When its temperature is that of melting ice (0° Centigrade, 32° Fahrenheit) two marks on that bar are exactly one metre apart. That Paris metre is the modulus of the world's weights and measures.* If the standard bar were lost, and all its master duplicates in the capitals of civilized countries, scientists would be hard put to recalculate the metre distance, except...
