Math Week is next week!

Math Week is now just a few days away.  A schedule of events follows.  Make note that a couple of the events require reservations.  So if you plan to attend one of those events, make sure you RSVP soon to Professor Lalani.  You can do so, by sending her an e-mail or signing up on her the list on her office door (VWF 214).  In addition to the following schedule of events, a book sale will take place in the Reading Room (VWF 222) and entries for Grand Prize Raffle will be collected all week long.

Michigan Autumn Take Home (MATH) Challenge

Professor Harrelson to talk on "Proportions and Odds, What's the Difference?"

This week's colloquium will be given by Professor Dyana Harrelson.  She will present "Proportion and Odds, What's the Difference?" on Thursday, October 24 at 4:00 p.m. in VWF 104.  Professor Harrelson will look at two case studies.  One examines the possibility that taking vitamin C can reduce the chance of getting a cold.  The other looks at the relationship between smoking and cancer.  Through the two case studies, she will show statistical procedures for comparing proportions as well as those for comparing odds.  No prior knowledge of statistics will be assumed for this colloquium.  This colloquium will also serve as an introduction to the statistical modeling course that will be taught next semester.
 

Surfing the Web

What do origami, knot theory, dissection, tiling, and fractals all have in common?  They are all a part of the Geometry Junkyard web site.  You can find this site at http://www.ics.uci.edu/~eppstein/junkyard.  This site, created by David Eppstein of the University of California Irvine, contains, web links, lecture notes, research excerpts, programs, problems, and other things related to geometry. Some serious and some just entertaining.  For example, you can see a proof for the honeybee conjecture or see how someone tiled their bathroom with pentagonal tiles.  There is even a link to where you not only can buy a Klein bottle, but a Klein stein or a Klein hat as well!
