81. The History Of Matrices olga Taussky Todd in American Mathematical Monthly. (quotation sourcehttp//www.maa.org/mathland/mathtrek_8_16_99.html) http://www.ualr.edu/lasmoller/matrices.html

Did you know . . .? The history of matrices goes back to ancient times! But the term "matrix" was not applied to the concept until 1850. "Matrix" is the Latin word for womb, and it retains that sense in English. It can also mean more generally any place in which something is formed or produced. The orgins of mathematical matrices lie with the study of systems of simultaneous linear equations. An important Chinese text from between 300 BC and AD 200, Nine Chapters of the Mathematical Art Chiu Chang Suan Shu ), gives the first known example of the use of matrix methods to solve simultaneous equations. In the treatise's seventh chapter, "Too much and not enough," the concept of a determinant first appears, nearly two millennia before its supposed invention by the Japanese mathematician Seki Kowa in 1683 or his German contemporary Gottfried Leibnitz (who is also credited with the invention of differential calculus, separately from but simultaneously with Isaac Newton). More uses of matrix-like arrangements of numbers appear in chapter eight, "Methods of rectangular arrays," in which a method is given for solving simultaneous equations using a counting board that is mathematically identical to the modern matrix method of solution outlined by

The conference showcased the research of outstanding women in mathematics and highlighted various issues of concern to young women entering the mathematical research communty. The career of Olga Taussky Todd (1906-1995) served as a worthy model for the participants... Though Taussky's main interest was initially number theory, she was to become what she later termed "a torchbearer" for another branch of mathematics known as matrix theory.

UIUC Seminar for Women in Mathematics Previous Semesters' Schedules Fall 2003 Schedule Date: Tuesday, September 16 Speaker: Stephanie Treneer Title: A Geometric Proof of Quadratic Reciprocity Abstract: Quadratic Reciprocity, originally proved by Gauss, was one of the first deep results about prime numbers, and one of the most beautiful in number theory. We will briefly discuss its history, and give a proof due to Eisenstein which employs elementary methods and a nice geometric argument. Date: Tuesday, September 30 Speaker: Jeong Ok Choi Title: Visibility Number of a Graph Abstract: With basic notions of graph theory, in this seminar the visibility number of a graph will be introduced due to prof. D. West. The visiblility number of a graph G, denoted b(G), is the minimum t such that G can be represented by assigning each vertex x the set S_x of points in at most t horizontal segments in the plane so that uv is an edge of G if and only if some point of S_u sees some point of S_v via a vertical segment of positive width unobstructed by assigned points. Also some examples and open problems will be mentioned. Date: Tuesday, October 28
