Lorenzo Mascheroni and Emmy Noether
Date: 11/15/95 at 11:29:46 From: Anonymous Subject: History Lorenzo Mascheroni made some kind of discovery? Also, what woman mathematician was born in 1882 and at what U.S .college did she end her teaching career?

You can find biographies of mathematicians and all kinds of other information on math history by consulting the Math Forum's Internet Mathematics Library: http://mathforum.org/library/ http://mathforum.org/library/topics/history/ 2) There's a biography of Mascheroni on the Web at http://www-groups.dcs.st-and.ac.uk:80/~history/Mathematicians/Mascheroni.html It says: Mascheroni was a geometer who proved in 1797 that all Euclidean constructions can be made with compasses alone and so a ruler is not required. Mascheroni was ordained as a priest at the age of 17. At first he taught rhetoric; then, from 1778, he taught physics and mathematics at the seminary at Bergamo. In 1786 Mascheroni became professor of algebra and geometry at the University of Pavia. He later became rector of the university. In Adnotationes ad calculum integrale Euleri (1790) Mascheroni calculated Euler's constant to 32 decimal places. In fact only the first 19 places were correct and the rest was corrected by Johann von Soldner in 1809. Mascheroni's work shows a deep understanding of the Euler's calculus. Mascheroni is also known as a poet and he dedicated one of his books Geometria del compasso (1797) to Napoleon in verse. In this work Mascheroni proved that all Euclidean constructions can be made with compasses alone, so a straight edge in not needed. In fact this was (unknown to Mascheroni) proved in 1672 by a little known Danish mathematician Georg Mohr. Mascheroni also wrote a well-composed book Nuove ricerchi su l'equilibrio delle volte (1785) on statics. 3) For your woman mathematician born in 1882, try looking up http://www.scottlan.edu/lriddle/women/noether.htm for a biography of Emmy Noether, who was born in 1882 and after coming to the United States taught at Bryn Mawr College until her death in 1935.
