Johannes Frischauf
Johannes Frischauf (17 September 1837 in Vienna – 7 January 1924 in Graz) was an Austrian mathematician, physicist, astronomer, geodesist and alpinist. Life and work Frischauf passed the matura at the Academic Gymnasium in Vienna and in 1857 studied mathematics, physics, astronomy at the University of Vienna, as well as geodesy, chemistry, mechanics at the Technischen Hochschule Vienna. He obtained the doctorate in 1864, and became Privatdozent for mathematics at the University of Vienna and assistant at the observatory of the university. In 1863 he was habilitated in mathematics. Starting in 1863, he was professor at the University of Graz for pure and applied mathematics. He worked together with Ludwig Boltzmann. Frischauf developed a new method of map design and wrote textbooks on arithmetics and geometry – for instance in 1872 and 1876 he wrote summaries of the then current knowledge about non-Euclidean geometry (which he called "absolute geometry"). In 1885 he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mathematics
Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes. These topics are represented in modern mathematics with the major subdisciplines of number theory, algebra, geometry, and analysis, respectively. There is no general consensus among mathematicians about a common definition for their academic discipline. Most mathematical activity involves the discovery of properties of abstract objects and the use of pure reason to prove them. These objects consist of either abstractions from nature orin modern mathematicsentities that are stipulated to have certain properties, called axioms. A ''proof'' consists of a succession of applications of deductive rules to already established results. These results include previously proved theorems, axioms, andin case of abstraction from naturesome basic properties that are considered true starting points of ...
