Карл Фридрих Гинденбург: Неміс математигі және комбинаторикасының дамуына қосқан үлесі

German mathematician
Carl Friedrich Hindenburg (13 July 1741 – 17 March 1808) was a German mathematician born in Dresden. His work centered mostly on combinatorics and probability.

Hindenburg did not attend school but was educated at home by a private tutor as arranged by his merchant father. He went to the University of Leipzig in 1757 and took courses in medicine, philosophy, Latin, Greek, physics, mathematics, and aesthetics. Hindenburg later published on philology in 1763 and 1769.

Hindenburg's first published mathematical publication, Beschreibung einer ganz neuen art, nach einem bekannten Gesetze fortgehende Zahlen, durch Abzahlen oder Abmessen bequem und sicher zu finden, originated as a project to extend then existing prime tables up to 5 million. In the book, he mechanically realizes, independent of the work done by Felkel, the sieve of Eratosthenes, which he then proceeds with rules to both optimize and organize. The book also contained results in linear diophantine analysis, decimal periods, combinations, and gave combinatorial significance to the digits of numbers written in decimal notation. In 1778, he started publishing a series of works on combinatorics, particularly on probability, series and formulae for higher differentials. He worked on a generalization of the binomial theorem and was a major influence in Gudermann's work on the expansion of functions into power series.

Hindenburg co founded the first German mathematical journals. Between 1780 and 1800, he was involved at different times with the publishing of four different journals all relating to mathematics and its applications. Two of the journals, the Leipziger Magazin für reine und angewandte Mathematik (1786–1789) and the Archiv für reine und angewandte Mathematik (1795–1799), published Johann Heinrich Lambert's Nachlass as edited by Johann Bernoulli. In 1796, he edited the Sammlung combinatorisch analytischer Abhandlungen, which contained a claim that de Moivre's multinomial theorem was “the most important proposition in all of mathematical analysis”. Another student, Johann Karl Burckhardt published the book Theorie der Kettenbrüche after being encouraged by Hindenburg to work on continued fractions. He also influenced Christian Kramp's work in combinatorics.
