What is Eugenio Beltrami?
[[Image:Beltrami.jpg|thumb|170px|Eugenio Beltrami]] '''Eugenio Beltrami''' (16 November 1835 {{ndash}} 18 February 1900) was an [[italy|Italian]] [[mathematician]] notable for his work on [[non-Euclidean geometry]], [[electricity]], and [[magnetism]]. He was born in [[Cremona]] in [[Lombardy]], then a part of the [[Austrian Empire]], and now part of Italy. Beltrami first began studying mathematics at the University of [[Pavia]] in 1853, but was forced to discontinue his studies in 1856 because of financial hardship. He was appointed to the [[University of Bologna]] as a professor in 1862, the year he published his first paper. Beltrami later taught at universities in [[Pisa]], [[Rome]] and Pavia. He died in Rome in 1900. In 1868, (in ''Essay on an interpretation of non-Euclidean geometry'') Beltrami gave the first model of [[hyperbolic geometry]]. In Beltrami's model, lines of hyperbolic geometry are represented by [[geodesic]]s on the [[pseudosphere]]. Beltrami provided the first proof that Euclid's [[parallel postulate]] could not be derived from the other axioms of [[Euclidean geometry]]. ==Other websites== * http://www-gap.dcs.st-and.ac.uk/~history/Mathematicians/Beltrami.html {{Webarchive|url=https://web.archive.org/web/20170420105403/http://www-gap.dcs.st-and.ac.uk/~history/Mathematicians/Beltrami.html |date=2017-04-20 }} {{DEFAULTSORT:Beltrami, Eugenio}} [[Category:1835 births]] [[Category:1900 deaths]] [[Category:Italian mathematicians]] [[Category:People from Cremona]] [[Category:Geometers]]
