Carl Cranz
Carl Julius Cranz (born January 2, 1858 in Hohebach , † December 11, 1945 in Esslingen am Neckar ) was a German mathematician and physicist. He is considered one of the founders of modern ballistics .
resume
Cranz was born the son of a pastor. He studied philosophy and theology at the University of Tübingen from 1877 to 1879; he was a member of the Normannia Association . From 1879 to 1883 he studied mathematics and physics in Berlin and Tübingen; In 1883 he received his doctorate on a subject of ballistics with Paul Du Bois-Reymond . Then he worked as an upper secondary school teacher and actuary; He was also a private lecturer in mathematics and mechanics at the TH Stuttgart (1884-1903), full professor at the Military Technical Academy (1903-1920) in Berlin, full professor for technical physics at the TH Berlin (1929-1935) and scientific advisor to Chinese government in Nanking (1935–1937).
Works
Even during his employment as a teacher in Stuttgart , Cranz gained a certain degree of awareness through ballistic research that went beyond the limits of his actual activity. That is why he was appointed to the then newly founded Military Academy in Berlin in 1903 to set up the world's first ballistic center for theoretical and practical research.
There he developed and improved theoretical approaches to ballistics as well as new methods in physical measurement technology.
He was one of the first to recognize the importance of supersonic wind tunnels and was working on rocket propulsion as early as the 1920s .
His work was and is important for many areas of applied physics , so
- his theoretical investigations on the gyro and Magnus effect
- his work on air resistance at high speeds
- his developments in high-frequency cinematography , such as the spark slow-motion camera in cooperation with Hubert Schardin for registering high-speed processes with image frequencies of up to 10 7 frames / sec. (so-called Cranz-Schardin method )
- his experiments on the construction of reliable and accurate time standards
In the 1941 yearbook "Die Wehrmacht" he wrote the article "With long-range bombers in the Mediterranean".
Honors
The Carl Cranz Society bears his name. The so-called Cranzbau (his place of work), the building of the Military Technical Academy on the site of the former Army Weapons Office , was named after him.
