Ludwig August Seeber

from Wikipedia, the free encyclopedia

Ludwig August Seeber (born November 14, 1793 in Karlsruhe , † December 9, 1855 there ) was a German mathematician and physicist.

Life

Ludwig August Seeber was born in Karlsruhe in 1793. Between 1819 and 1822 he was a teacher at the military school in Karlsruhe. He then became a professor of physics at the University of Freiburg im Breisgau . From 1834 he was a professor at the Polytechnic in Karlsruhe . He was not particularly successful and retired early in 1840 due to disciplinary problems. He died in 1855.

Scientific results

The reduction of crystal lattices has been an active research area in crystallography until very recently. Seeber introduced the first process for this in 1831, the so-called reduced form. This work was largely overlooked and re-derived in 1928 by Paul Niggli . He found 44 reduced forms. Niggli's work was also overlooked at first. In 1933 Boris Nikolajewitsch Delone introduced lattice reduction into crystallography.

reception

George Szpiro describes Seeber as an unknown professor of physics and mathematics. His book, Investigations into the Properties of Positive Ternary Square Shapes, is lengthy and extremely tiresome. However, the book was reviewed by Carl Friedrich Gauß . Seeber needed over 600 calculations on 248 pages to arrive at his guess. In his review, Gauss only needed forty lines to provide the mathematical proof. According to Szpiro, the review had a greater impact on mathematics than Seeber's original work.
