Fritz Goos

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

Life and work

Goos attended the grammar school of Johanneums in Hamburg, where he received in March 1902 his matriculation certificate. He then worked until April 1903 in the Hamburg factory of machines Wimmel & Landgraf. In October 1903 he began to study mathematics and science at the Royal Institute of Technology in Berlin. In March 1905 he joined in the summer semester at the University of Bonn to study astronomy and mathematics. The following winter semester, he continued this study in Berlin continued, but then went in April 1906 back to Bonn, where he became in 1908 a Doctor of Philosophy ( Dr. phil. ) PhD Astronomy in the area.

After graduating, he became an assistant at the observatory in Bonn and took 1909 assistant at the observatory in Hamburg- Bergedorf. From 1911 he worked at the Physical State Institute (founded in 1885 as a Physical State Laboratory ) in Hamburg, where he worked as a scientific advisor ( until 1948? ).

As an adjunct professor at the University of Hamburg in the " Optical Spectroscopy " he studied the emission and absorption features in the infrared, optical and ultraviolet spectral range of different objects, such as the arc or thin metallic layers such as silver and gold. Discovering the end of 1912, a systematic dependence of the wavelengths in the spectrum of an arc of its length and its electrical parameters, such as the used current. In the spring of 1913 Goos could these observations confirm the better-equipped physical laboratory of Heinrich Kayser in Bonn. Furthermore, he was also involved in 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 evidence of displacement of a light beam in total reflection together with Hilda Hänchen (later Hilda Lindberg - Hänchen ), called the Goos- Hänchen shift.
