…This group was a highly interdisciplinary group consisting of physiologists, mathematical physicists, astrophysicists, mathematicians, army officers, and surveyors. The British Fredrick W. Lanchester (1868-1946) also derived the famous Lanchester Law regarding combat. In other words, when two armies with forces x ( t ) and y ( t ) are fighting, the change in the number of troops is expressed as the differential equation dy / dx = Ex / y , and the solution to this equation was the square law, y 0 2 - y 2 = E ( x 0 2 - x 2 ). … *Some of the terminology used in reference to "Lanchester, FW" is listed below.
