Joseph Stilwell the parents of five children, including Brigadier General Joseph, Jr., (West Point 1933) served in World War II, Korea, and Vietnam. Stilwell later taught at West Point, and attended the Infantry Advanced Course and the Command and General Staff College. During World War I, he was the U.S. Fourth Corps intelligence officer and helped plan the St. Mihiel offensive. He was awarded the Distinguished Service Medal for his service in France. Stilwell is often remembered by his sobriquet, "Vinegar Joe", which he acquired while a commander at Fort Benning, Georgia. Stilwell often gave harsh critiques of performance in field exercises,
Ives–Stilwell experiment speeds below 36 km/h (< 10 m/s, the speed of a fast runner) by comparing the rates of moving and resting aluminum ions. It was also possible to detect gravitational time dilation from a difference in elevation between the two clocks of 33 cm. Ives–Stilwell experiment The Ives–Stilwell experiment tested the contribution of relativistic time dilation to the Doppler shift of light. The result was in agreement with the formula for the transverse Doppler effect and was the first direct, quantitative confirmation of the time dilation factor. Since then many Ives–Stilwell type experiments have been performed with increased precision. Together
