6 Do not worry about your mistakes Once more let me begin with Hilbert. When the Germans were planning to publish Hilbert's collected papers and to present him with a set on the occasion of one of his later birthdays, they realized that they could not publish the papers in their original versions because they were full of errors, some of them quite serious. Thereupon they hired a young unemployed mathematician, Olga Taussky-Todd, to go over Hilbert's papers and correct all mistakes. Olga labored for three years; it turned out that all mistake scould be corrected without any major changes in the statement of the theorems. There was one exception, a paper Hilbert wrote in his old age, which could not be fixed; it was a purported proof of the continuum hypothesis, you will find it in a volume of the Mathematische Annalen of the early thirties. At last, on Hilbert's birthday, a freshly printed set of Hilbert's collected papers was presented to the Geheimrat . Hilbert leafed through them carefully and did not notice anything. Now let us shift to the other end of the spectrum, and allow me to relate another personal anecdote. In the summer of 1979, while attending a philosophy meeting in Pittsburgh, I was struck with a case of detached retinas. Thanks to Joni's prompt intervention, I managed to be operated on in the nick of time and my eyesight was saved.

Olga Taussky Todd Olga Taussky Todd, a major presence in mathematics, died on October 7, 1995, in Pasadena, California, at the age of 89. In 1937 she took a position at the University of London, where she met her dashing husband-to-be, John (Jack) Todd, from Belfast, Ireland. According to Olga, they met when Jack asked her for help on a technical mathematics question, which she was initially unable to supply; they were married at the end of 1938. During World War II, Olga was employed by the British Ministry of Aircraft Production at the National Physical Laboratory. There, she worked on the flutter analysis of wings of subsonic and supersonic aircraft, and she was one of the first to apply the Gerschgorin circle theorem to a practical problem of estimating numerically the eigenvalues of a matrix. Olga and Jack came to the United States in 1947 to be researchers at the National Bureau of Standards. They remained at NBS until 1957, when they accepted professorships at the California Institute of Technology in Pasadena. Olga received the Ford Prize of the Mathematical Association of America for her paper "Sums of Squares" ( American Mathematical Monthly , Vol. 77, 1950, pages 805- 830). She was elected to the Austrian and Bavarian Academies of Science and was named a Fellow of the American Association for the Advancement of Science. She was an editor of the

Papers based on the plenary talks will be featured in a volume about AWM; the plan of the book will be described in that Newsletter. The Celebration featured the legacy of Olga Taussky Todd (1906-1995), who was an inspiration to a number of the mathematicians present. Among her many other achievements, Taussky Todd presented the Noether Lecture of the Association for Women in Mathematics in 1981. This AWM-organized conference drew over one hundred women and men mathematicians to the Mathematical Sciences Research Institute at Berkeley for three days of information, inspiration, camaraderie. There was agreement that the primary goals of the celebration were well met: to assist, encourage and inspire the participating beginning mathematicians, to provide a forum for networking between mathematicians at different career stages and to promote the achievements of women in mathematics. Forty of the participants were women graduate students or recent Ph.D.'s. Most of them presented their mathematical research in three poster sessions. Their enthusiasm and thoughtful questions were a motivation for the senior mathematicians; as an organized feature of the program, junior and senior women were paired in mentoring activities.

Matrices, Circles, and Eigenthings Last month, the Mathematical Sciences Research Institute (MSRI) in Berkeley, Calif., hosted the Olga Taussky Todd Celebration of Careers in Mathematics for Women. 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. Taussky was born in Olmütz, which was then part of the Austro-Hungarian Empire and is now in the Czech Republic. As a child, she loved writing, especially essays, poems, and also music. In high school, her interests turned to science, particularly astronomy, then finally to mathematics. Taussky studied at the University of Vienna, focusing on number theory in her doctoral dissertation. By 1937, she was working at the University of London, where she met and married mathematical analyst John Todd. 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.

The Olga Taussky/John Todd ILAS Lecture ======================================= Olga Taussky and John Todd have had a decisive impact on the development of theoretical and numerical linear algebra for over half a century. This lecture honors them for their many and varied mathematical achievements and for their efforts in promoting linear algebra and matrix theory. The lecture is to be given once every three to four years at an ILAS meeting designated by the ILAS executive committee. The lecturer should be a person who has received a Ph. D. degree within about fifteen years of the chosen ILAS meeting. The president shall appoint a committee consisting of at least four ILAS members to select a lecturer. The lecturer chosen should be a person who at an early stage in his or her career already has made significant contributions to linear algebra and matrix theory. The lecture should normally cover a broad area of current research in linear algebra or matrix theory and be of a survey or historical nature.

80. The History Of Matrices The elevation of the matrix from mere tool to important mathematical theory owesa lot to the work of female mathematician olga Taussky Todd (19061995), who 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
