Problem of the Week Competition

Here is the most recent problem.  Paper copies are available on the bulletin board outside LY 228.  Please scroll down to view the competition rules. 

 Spring 2016 PROBLEM 1: DUE WEDNESDAY, February 3 by 3pm  For this week, your task is to cut out the triangle on the back of this page using a pair of scissors.  Sounds easy, right?  But there’s a catch: you must do it using ONLY one straight cut.  This means that once you start cutting, you can’t turn the paper and you can’t turn your scissors.  (Hint: you may fold this piece of paper as many times as you wish).   To submit your solution, please fold your paper and then cut it out in front of Dr. Kronenthal (LY 264) or Dr. Wong (LY 213).  Don’t wait until the last minute, you need to catch one of us in our offices!
