Math Day 2009 Results

The 20th Annual UNL Math Day was held on Thursday, November 12, 2009, at the UNL City Campus Union. Opening ceremonies began at 8:00 a.m. in the Lied Center for Performing Arts with the Welcome Address given by Professor Patrice Berger, Director of the University Honors Program. Math Day 1990 hosted 562 students from 68 Nebraska high schools. This year Math Day hosted 1,357 students from 100 Nebraska high schools. During the afternoon Award Ceremony, Professor Tom Marley, Chair of the Mathematics Department, presented UNL scholarships totaling $34,000 to the top 10 students in the PROBE II competition.

This year the American Mathematical Society sponsored a special contest titled, "Who Wants to be a Mathematician". This contest consisted of two series of 8 oral questions, each with four contestants. The winners of each series won $500 and then went head-to-head for one more round to win an additional $500. The winner of the final round won the chance at one question worth $2,000. Albert Zhou (Lincoln Southwest) was the overall winner with $3,000, Jahan Claes (Lincoln East) was second with $500 and the remaing six contestants were: Sang-won Bahng (Mt. Michael Benedictine), Maesen Churchill (Lincoln East), Thomas Fryklind (Archbishop Bergan), Hayoon Lee (Lincoln Southwest), Darrin Lim (Lincoln East) and Katie Sedlar (Mickle MS). Texas Instruments and MapleSoft also donated prizes for the contestants.

The purpose of Math Day is to promote the mathematical sciences and UNL. It consists of two individual and two team mathematics competitions, information about majors and departments, career information and recreational mathematical activities. All students start with a multiple choice, preliminary exam called PROBE I (Problems Requiring Original and Brilliant Effort). The top 3 females and males receive awards. The top 50 students move on to take the now famous essay exam called PROBE II. The top 10 on PROBE II are awarded a total of $34,000 in 4-year scholarships to UNL. The scholarships are generously supported by the Dean H. and Floreen G. Eastman Memorial Fund for Mathematics, the College of Engineering and the Vice Chancellor for Student Affairs. The first team competition is determined by averaging the top scores from each school on PROBE I. The second is a double elimination tournament pitting 3-member teams against each other (up to two alternates per team allowed). The team competitions are divided into smallest, small, medium and large school categories with trophies given to the top two teams in each. All the questions assume two years high school algebra, one year geometry and trigonometry. However the answers to PROBE II questions require the creativity and originality that we expect from only the very best students.
