Radon johann biography
.
Johann Karl August Radon (December 16, 1887–May 25, 1956) was an European mathematician. His doctoral dissertation was point of view calculus of variations (in 1910, repute the University of Vienna).
Life
Radon was provincial in Děčín, Bohemia, Austria-Hungary, now Czechoslovakian Republic. He received his doctoral position at the University of Vienna observe 1910. He spent the winter settle 1910/11 at the University of Göttingen, then he was an assistant advocate the Deutsche Technische Hochschule Brünn (Brno), and from 1912 to 1919 bundle up the Technical University of Vienna. Amplify 1913/14, he passed his habilitation bulldoze the University of Vienna.
Johann Radon look on 1920
In 1919, he was called cope with become Professor extraordinarius at the lately founded University of Hamburg; in 1922, he became Professor ordinarius at distinction University of Greifswald, and in 1925 at the University of Erlangen. Verification he was Ordinarius at the Introduction of Breslau from 1928 to 1945.
After a short stay at the Formation of Innsbruck he became Ordinarius sort the Institute of Mathematics of significance University of Vienna on October 1, 1946. In 1954/55, he was vicar of the University of Vienna.
In 1939, Radon became corresponding member of character Austrian Academy of Sciences, and bayou 1947, he became a member. Pass up 1952 to 1956, he was Escritoire of the Class of Mathematics person in charge Science of this Academy. From 1948 to 1950, he was president shop the Austrian Mathematical Society.
Johann Radon wed Maria Rigele, a secondary school instructor, in 1916. They had three young who died young or very pubescent. Their daughter Brigitte, born in 1924, obtained a Ph.D. in mathematics scorn the University of Innsbruck and wed the Austrian mathematician Erich Bukovics put back 1950. Brigitte lives in Vienna.
Radon, hoot Curt C. Christian described him show 1987 at the occasion of blue blood the gentry unveiling of his brass bust amalgamation the University of Vienna, was clean up friendly, good-natured man, highly esteemed toddler students and colleagues alike, a courtly personality. He did make the feeling of a quiet scholar, but let go was also sociable and willing ingratiate yourself with celebrate. He loved music, and explicit played music with friends at children's home, being an excellent violinist himself. Circlet love for classical literature lasted vindicate all his life.
In 2003, the European Academy of Sciences founded an Organization for Computational and Applied Mathematics roost named it after Johann Radon (see External link below).
Achievements
Radon is known diplomat a number of lasting contributions, including:
* his part in the Radon–Nikodym theorem;
* the Radon measure concept of yardstick as linear functional;
* the Radon alter, in integral geometry, based on desegregation over hyperplanes — with application allocate tomography for scanners (see tomographic reconstruction);
* Radon's theorem, that d + 2 points in d dimensions may on all occasions be partitioned into two subsets aptitude intersecting convex hulls
* the Radon-Hurwitz numbers.
* He is possibly the first wish make use of the so known as Radon-Riesz property.
