Housed in a spectacular building redolent of crystals and light, the National Gallery of Canada in Ottawa was recently the setting for a highly unusual school event–a mathematics field trip!
For several years, math teacher Ron Lancaster of Hamilton, Ontario, has been creating "math trails" for both students and teachers as a...
Earlier this year, the journal Computing in Science & Engineering (CISE) published a list of the top 10 algorithms of the century (see http://computer.org/cise/articles/Top_Algorithms.htm).
"Computational algorithms are probably as old as civilization," Francis Sullivan of the Institute for Defense Analyses' Center for Computing Sciences in Bowie, Md. noted in an editorial in the...
