Sir Andrew NobleBorn 13 Sep 1831; died 22 Oct 1915 at age 84.(Baronet) Scottish physicist and gunnery expert, known as a founder of the science of ballistics. He invented the chronoscope, a device for measuring very small time intervals, and in about 1862, he used it to measure the velocity of shot in gun barrels. His investigations in ballistics led to the redesign of guns, new methods of loading, and development of new types of gunpowder. |
