Return to The Worlds of David Darling INDEX LATEST NEWS ARCHIVE ... Z entire Web this site Coxeter, Harold Scott MacDonald (1907-2003) A British-born, Cambridge-educated mathematician who spent most of his career (from 1936 on) at the University of Toronto and was regarded as the greatest classical geometer of his generation. Always known as "Donald," he is best known for his work on hyperdimensional geometries and regular polytopes In 1926, at the age of 19, Coxeter discovered a new regular polyhedron, having six hexagonal faces at each vertex. He went on to study the mathematics of kaleidoscopes and, by 1933, had enumerated the n -dimensional kaleidoscopes. His algebraic equations expressing how many images of an object may be seen in a kaleidoscope are now known as Coxeter groups . His research on icosahedral symmetries played an important role in the discovery by scientists at Rice University, Texas, of the carbon-60 molecule (see buckyball ), for which they won the 1996 Nobel Prize in Chemistry.

COXETER ON 'FIRMAMENT' It is known [H.S.M. Coxeter, 'Loxodromic Sequences of Tangent Spheres', , 1 (1968), pp. 112-117] that, for a sequence of circles n such that every 4 consecutive members are mutually tangent, the inversive distance n between and n (or between m and m+n for any m ) is given in terms of the Fibonacci numbers f n by the formula For the analogous sequence of spheres, such that every 5 consecutive members are mutually tangent, a prize is offered to the first person who provides the analogous formula for the inversive distances between pairs of the spheres. Meanwhile, by taking one pair of adjacent 'spheres' to be a pair of parallel planes, one easily finds that the values of cosh n are n cosh n John Robinson's sculpture FIRMAMENT is based on seven such spheres whose radii are in geometric progression; that is, the seven radii are proportional to 1/x , 1/x , 1/ x, 1, x, x , x where x is the root, between 1 and 2, of the quintic equation x - x - x - x - x + 1 = . This equation has a root and the remaining quartic is easily solvable as a quadratic in x + 1/x to give x as or approximately 1.8832. This gives the radii previously described.

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.

"He was a math professor while I was a student here," Birgeneau said. "He was actually working on a paper for publication at age 96 it was just completed. It's truly astounding, almost eight decades of creative contributions to mathematics and geometry." Birgeneau added that Coxeter was "a great person, a great teacher and symbolic of everything I'd like to think we stand for here at the University of Toronto."

78. Mousing Around> I can’t resist making a few remarks about Professor coxeter. which referredto him as the Venerable donald coxeter high priest of mathematics . http://www.cs.ualberta.ca/~smillie/APE/APE23.html

Mousing Around Keith Smillie Chocolate Mathematics In the previous issue of Epilogue there was a problem in which one picked a one-digit number, performed a few arithmetical operations on it, and obtained what might have appeared to be a surprising result. In this column we shall give a simple explanation, but first we shall make a few general remarks about such problems. This problem is typical of a large number of problems, most of which require only some simple arithmetic and possibly a little very elementary mathematics for an explanation. They may be introduced at times into mathematics classes to provide some entertainment while illustrating important mathematical principles. I often used some of them to illustrate positional number systems, both the familiar decimal system and also systems to bases other than ten. The classic book on this topic is Mathematical Recreations and Essays by W. W. Rouse Ball who was a fellow of Trinity College, Cambridge from 1878 to 1905. He may be best known as an historian of mathematics and his short history of mathematics published in 1888 gave a very readable account of the subject. (I recently saw a facsimile edition published a year ago of the fifth edition of this book which appeared in 1912.) Mathematical Recreations was first published in 1892 and has gone through fourteen editions with the last four being revised by H. S. M. Coxeter of the University of Toronto.

80. SF News - May 4, 2000 - Visualizing Mathematics Highlighting the conference was a public lecture by donald coxeter, a mastergeometer who has written a dozen books and published more than 160 articles on http://www.sfu.ca/mediapr/sfnews/2000/May4/coxeter.html

May 4, 2000 Vol . 18, No. 1 Visualizing mathematics By Carol Thorbes Visualization is a technique often associated with personal problem solving. But many mathematicians say it is just as crucial to their work. The Pacific Institute for the Mathematical Sciences' (PIMS) explored this connection at its third annual conference, Changing the Culture 2000-Visualizing Mathematics , in April at SFU's Harbour Centre campus. "The ability to visualize the interaction of lines, shapes and solids is key to understanding and solving complex mathematical problems, especially in geometry. It is also a basis for seeing with your mind's eye more abstract mathematical concepts," notes Malgorzata Dubiel, a lab instructor in SFU's department of mathematics and statistics and the conference's main organizer. Sponsored by PIMS' five founding universities, including SFU, the conference demonstrated the importance of incorporating visualization techniques in teaching mathematics at all levels of education and in mathematics research. Highlighting the conference was a public lecture by Donald Coxeter, a master geometer who has written a dozen books and published more than 160 articles on the subject. The professor emeritus of the University of Toronto's math department is famous for his investigation of regular polytopes, the process of stretching geometrical shapes into higher-dimensional spaces, real and complex.
