61. Donald Coxeter On John Robinson's Sculpture Firmament quadratic in x + 1/x to give x as. or approximately 1.8832. This givesthe radii previously described. donald coxeter, January 1997. http://www.bangor.ac.uk/cpm/sculmath/donald.htm

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.

Some samples are incubated at near-body temperatures. The outbreak of Severe Acute Respiratory Syndrome [SARS] that has struck in Toronto and around the world over the past couple of weeks has been a real test for our public health system. We know neither the cause, the origin or the ultimate danger that may result from this mysterious illness. Dr. Eleanor Fish Dr. Amin Kabani is Chief of Bacteriology at the National Microbiology Laboratory and an associate professor of Microbiology and Pathology at the University of Manitoba. He's helping to lead the team at the Canadian Microbiology Laboratory that's trying to identify the virus, or viruses that are causing SARS, and he explains how his team goes about identifying what's causing an outbreak like SARS. SARS is a public health problem, but it's also serving as a dry run for the outbreak that many epidemiologists really fear: The next big influenza epidemic. The flu infects millions, and kills thousands of Canadians every year. The worst case scenario for the flu, however, is an oubreak that could kill up to 30% of those it infects — like the 1918 flut that killed millions worldwide.

April 19, 2000 VISUALIZATION LEADS TO SOLVING MATH PROBLEMS AT SFU CONFERENCE Visualization is a technique often associated with personal problem solving. But many mathematicians say it is just as crucial in their work. The Pacific Institute for the Mathematical Sciences' (PIMS) will explore this connection in its third annual conference Changing the Culture 2000-Visualizing Mathematics on Friday, April 28, at Simon Fraser University'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 will demonstrate the importance of incorporating visualization techniques in teaching mathematics at all levels of education and in mathematics research.

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.

Coxeter, University of Toronto April 28, 2000 5:00 PM Watch lecture now using the Real Player software. A few transparencies have been scanned to accompany this streaming video. They appear at approximately: after the start. Abstract: While the public lecture by H.S.M. Coxeter will touch on various mathematical aspects of M.C. Escher's art, its centre-piece is likely to be an examination of Escher's circular woodcuts. The following is Coxeter's introduction (with two minor verbal substitutions for mathematical notation) to a paper which appeared in the Mathematical Intelligencer , No.4, 1966. Born 9 Feb 1907 in London, England, Donald Coxeter is always known as Donald which comes from his third name MacDonald. This needs a little explanation. He was first given the name MacDonald Scott Coxeter, but a godparent suggested that his father's name should be added, so Harold was added at the front. Another relative noted that H M S Coxeter made him sound like a ship. A permutation of the names resulted in Harold Scott MacDonald Coxeter. Donald was educated at the University of Cambridge, receiving his B.A. in 1929. He continued to study for a doctorate at Cambridge under H F Baker, and this was awarded in 1931. He then became a Fellow continuing his researches at Cambridge. During this period he spent two years as a research visitor at Princeton University.

The two 14-year-old boys are in side-by-side beds recovering from the flu in their private school's sick-room. H.G. Wells's classic science fiction story The Time Machine is a popular topic of conversation. Both boys are very bright and believe time travel will eventually be possible. "I suppose one might find it necessary to pass into the fourth dimension," says Coxeter.

80. The Silhouette Online Edition Witelson will be able to confirm these suspicions with her newestacquisition, the brain of mathematical genius donald coxeter. http://sil.mcmaster.ca/archives/030925/life/030925ein.html

September 25, 2003 McMaster University's Student Newspaper Volume 74, Issue 6 Einstein’s unique brain Noah Frank Life Editor There exists a sensational, if not at times specious, story concerning Albert Einstein’s brain. Perhaps the greatest mathematical mind of the twentieth century, Einstein succumbed to a ruptured abdominal aneurysm on April 18, 1955 at Princeton University Hospital. Thomas Harvey, the pathologist responsible for the autopsy and subsequent removal of Einstein’s brain, was on hand at the time of death. Although it is often disputed, Harvey received consent for the procedure from both Einstein and his next of kin. Bizarrely, Harvey also gained ownership of the brain, which has been in his possession since. Several accusations have been launched surrounding Harvey’s treatment of the brain; among these is Carolyn Abrahams’ allegation in her publication Possessing Genius: The Bizarre Odyssey of Einstein’s Brain that Harvey stored the sectioned brain in two mason jars, inside two cardboard boxes marked “Costa Cider.” Whether fact or fiction, Harvey maintained ownership of the brain, soliciting lab work from various professionals. Consequently, Einstein’s brain was well-preserved and documented. Harvey has lent the brain to three major studies over the years, one of the most celebrated being conducted at McMaster University by Sandra Witelson. Witelson was the first to detect both qualitative and statistically quantitative differences between Einstein’s brain and a control group of brains. Her paper, The Exceptional Brain of Albert Einstein, published in The Lancet (June, 1999), has caused quite a stir among neuroscientists, psychologists and the general public.
