Bichromatic Plane Patterns , and Dynamic Symmetry The Mathematics and the Liberal Arts pages are intended to be a resource for student research projects and for teachers interested in using the history of mathematics in their courses. Many pages focus on ethnomathematics and in the connections between mathematics and other disciplines. The notes in these pages are intended as much to evoke ideas as to indicate what the books and articles are about. They are not intended as reviews. However, some items have been reviewed in Mathematical Reviews , published by The American Mathematical Society. When the mathematical review (MR) number and reviewer are known to the author of these pages, they are given as part of the bibliographic citation.

Kantor, Lino Di Martino In stock Presented here are papers from the 1993 Como meeting on groups of Lie type and their geometries. The meeting was attended by many leading figures, as well as younger researchers in this area, and this book brings together many of their excellent contributions. Themes represented here include: subgroups of finite and algebraic groups; buildings and other geometries associated to groups of Lie type or Coxeter groups; generation and applications. This book will be a necessary addition to the library of all researchers in group theory and related areas. Contributors Michael Aschbacker, Alexandre V. Borovik, K.

88. Interview Vol. 23 (1971), 718745. The path then led from John Leech to Donaldcoxeter, and from coxeter to John Conway. Incidentally this http://www.research.att.com/~njas/doc/interview.html

Interview with Neil Sloane A slightly different version of the following interview appeared in the IEEE Information Theory Society Newsletter , volume (number 4), December 1997, pages 3-4, 35-37. The interviewer is Robert Calderbank, editor-in-chief of the IEEE Transactions on Information Theory. The photograph was taken by Laine Whitcomb, Photographer, 105 East 2nd St. NY NY 10009; (212) 677 6754. Q: How did you come to do a Ph.D. in electrical engineering (rather than mathematics, say), and why at Cornell? A: During my years as an undergraduate at the University of Melbourne (in Australia) I had a scholarship from the state phone company, which in those days was called the Postmaster General's Department. So in a sense I have been working for "the phone company" ever since 1956. I think that's the main reason I chose engineering rather than mathematics, because of this scholarship. In fact I ended up doing two four-year undergraduate degrees more or less simultaneously, one in electrical engineering and one in math. I remember that during the summer breaks we had to learn how to erect telephone poles, to splice cables with hot lead while sitting at the top of these poles, to test telephone circuits, to drive 10-ton trucks, and so on.

FIRMAMENT "Let there be a Firmament in the midst of the waters, and let it divide the waters." Genesis: Chapter 1: verse 6 On February 9th 1997, Professor Donald Coxeter of the University of Toronto celebrated his 90th Birthday. I am delighted to say that through the generosity of Robert A. Hefner III and Damon de Laszlo, the Fields Institute for Research in Mathematical Sciences have placed my Symbolic Sculpture INTUITION outside their building to mark the day. When I met Donald he told me about a 'geometric progression' that he had discovered, where spheres were 'mutually tangent' (see Coxeter on 'Firmament ). He asked me if I thought it would be possible to use his findings in a sculpture, and explained that the radii of the spheres are, if the unit is a decimetre, 1.5cm, 2.8cm, 5.3cm, 10cm, 18.8cm, 35.5cm, 66.8cm. I could use only the first five spheres as numbers 6 and 7 in the sequence are too big to handle. I had the 5 spheres spun by a wood turner, and only when I put the jigsaw puzzle together was I able to see the miracle that Donald had perceived through his mathematical vision. I mounted the spheres on a vertical rod capped by a plane set at 23.5 degrees to the horizontal plane, and used an
