DONALD COXETER Né à Londres le 9 février 1907, de son vrai nom Harold Scott MacDonald Coxeter, il est mieux connu sous le surnom de Donald. Etudiant à l’Université de Cambridge, il obtient sa licence en 1929. En 1931, ayant acquis son doctorat à Cambridge même, il y reste pour poursuivre des recherches. Durant l’année 1936, un poste à l’Université de Toronto s’offre à lui, université pour laquelle il travaille depuis plus de 60 ans. Coxeter a surtout travaillé en géométrie où il a grandement contribué à l’évolution de la théorie des polytopes et à la géométrie non euclidienne. Ces polytopes sont des formes géométriques que l’on augmente d’une dimension, ce procédé étant appelé Dimensional Analogy. Ainsi, il étend la géométrie des polytopes à la quatrième dimension et même au-delà. Ce que motive Coxeter dans ses recherches est la beauté des mathématiques. D’ailleurs, Robert Moody de la York University de Toronto considère que les sciences modernes, dont en font partie les mathématiques, suivent une certaine mode. Ce qu’il trouve de remarquable au style de Coxeter est sa faculté d’échapper à un phénomène de mode et de n’être guidé que par ce qu’est la beauté. De plus, son goût pour les domaines artistiques est aussi marqué par son intérêt pour la musique. En effet, il aurait désiré être compositeur avant de se lancer dans les mathématiques. A l’âge de 14 ans, ayant trop de facilité à l’école, il imagine les formes géométriques en dimensions supérieures et rédige déjà ses premières idées à ce sujet. Son père, grand ami du philosophe Bertrand Russell, amène son fils chez celui-ci. Russell aide Coxeter à se trouver un excellent professeur de mathématiques, le Professeur H.F. Baker de l’Université de Cambridge.

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. Highlighting the conference will be a public lecture by Donald Coxeter, a master geometer who has written a dozen books and published more than 160 articles on the subject.
