Fritz Goos

Hermann Fritz Gustav Goos (born January 11, 1883 , Hamburg ; † May 18, 1968 , ibid) was a German physicist and astronomer .

life and work

Goos visited the secondary school of the Johanneum in Hamburg and got there in March 1902 his school leaving certificate . He then worked in the Wimmel & Landgraf machine factory in Hamburg until April 1903 . In October 1903 he began studying mathematics and natural sciences at the Royal Technical University in Berlin . During his studies he became a member of the Corps Rheno-Guestphalia Berlin . In March 1905 he switched to the University of Bonn in the summer semester to study astronomy and mathematics. In the following winter semester he continued his studies in Berlin, but then went back to Bonn in April 1906, where he received his doctorate in philosophy (Dr. phil.) In the field of astronomy in 1908 .

After his studies he became an assistant at the observatory in Bonn and in 1909 accepted an assistant position at the observatory in Hamburg-Bergedorf . From 1911 he worked at the State Physics Institute (founded in 1885 as the State Physics Laboratory ) in Hamburg, where he also worked as a scientific advisor (until 1948?).

As an adjunct professor at the University of Hamburg in the field of "Optical Spectroscopy", he dealt with the emission and absorption properties in the infrared, optical and ultraviolet spectral range of different objects such as the electric arc or thin metallic layers such as silver and gold. At the end of 1912 he discovered a systematic dependence of the wavelengths in the spectrum of an arc on its length and its electrical parameters, such as the current strength used . In the spring of 1913 Goos was able to confirm these observations in Heinrich Kayser's better equipped physical laboratory in Bonn. Furthermore, it also dealt with the effect of light on phosphors and with the detection of light through a micro- photometer . One of his best-known works is the experimental proof of an offset of a light beam during total reflection together with Hilda Hänchen (later Hilda Lindberg-Hänchen), the so-called Goos-Hänchen shift .
