Professor Tanis will show how Maple can help you become
|If you thought the computer algebra system Maple could just help you solve a differential equation or evaluate an integral, you are wrong. Professor Emeritus Elliot Tanis will show us, in tomorrow's colloquium, that Maple can be used to make art. On Thursday, November 21, at 4:00 p.m. in VWF 104, Professor Tanis will present "Using Maple to Construct Tessellations Inspired by M.C. Escher." He will be using examples from Chinese lattice designs, the Alhambra, Hungarian needlework, and M.C. Escher's tessellations. The way in which tessellations are classified will be illustrated and examples of some of the 17 plane symmetry groups will be shown.||

Surfing the Web
Eric Weisstein's World of Mathematics, or MathWorld, (found at http://mathworld.wolfram.com/) is self described as the web's most complete mathematical resource. MathWorld is a comprehensive mathematics encyclopedia and is indeed a very impressive site. The encyclopedia is organized both by subject and alphabetically. Particularly interesting are the topics under recreational mathematics. Under this subject heading, you can find games, illusions, magic squares, puzzles, and more. For example, the following classic spider and fly puzzle is given at that site.
In a rectangular room with dimensions 30'
x 12' x 12', a spider is located
in the middle of one 12' x 12' wall
one foot away from the ceiling. A fly is in the middle of the opposite
wall one foot away from the floor. If the fly remains stationary, what
is the shortest total distance the spider must crawl along the walls, ceiling,
and floor in order to capture the fly?

Hope beats Calvin!
Two teams from Hope College tied for third place in the Michigan Autumn
Take-Home (MATH) Challenge. Winning the competition with 90 points
was a team from Tri-State University in Angola, Indiana. Earning
85 points put a team from Albion in second place. There was a three
way tie for third place with two teams from Hope and one from Kalamazoo.
Two teams from Calvin followed in sixth and seventh place with 77 and 75
points respectively. While we are still not sure which of our teams
finished in third place, congratulations to all those that competed for
Hope; Heidi Libner, Daniela Banu, Chris VanSlooten, Ben Freeburn, Henry
Gould, Michael Rininger, and James Boerkoel.
