MathFest 2004 in Providence

Plan on participating in the activities planned for the Providence, Rhode Island, MathFest this summer, from Wednesday, August 11, through Saturday, August 14, 2004. The activities for students will include the Student Hospitality Center, the MAA Student Paper Sessions, the presentations of the MAA Mathematical Contest in Modeling winners, the MAA Student Lecture, the MAA Student Workshop, and the Student Problem Solving Competition. In addition, students and advisors will likely be interested in the parallel Pi Mu Epsilon student papers sessions, the PME banquet, the PME J. Sutherland Frame lecture, and a

Warm and sunny weather welcomed those who attended the JMM at Phoenix in January. A record number of students participated in the MAA student poster session, about one hundred students and advisors attended the MAA student lecture, many folks attended the special session on ’Mathematical Experiences for Students outside the Classroom,â? and students and others enjoyed the diversions offered at the Student Hospitality Center throughout the meetings. Thanks to the Diversity Initiative, some students from underrepresented groups received assistance with travel and registration expenses. For a report on these activities, check out the ’Photos and Fun Facts from Phoenix.â?

Well over one hundred students and advisors attended this year’s MAA student lecture. Dr. Mark M. Meerschaert of the University of Nevada enthusiastically presented a sample lecture of the course in ’fractal calculusâ? that students may get at Star Fleet Academy in the future. In his talk he introduced students to the notions of fractional derivatives, PDEs with fractional derivatives, and non-normal random diffusion processes. In speaking of the joys of playing with wild ideas in mathematics, like fractional derivatives, he exclaimed, ’You screw around and useful things happen! What could be better?â? Copies of the slides of his talk may still be seen at http://unr.edu/homepage/mcubed. |

Richard and Araceli Neal Host the Student Hospitality Center

Despite a last-minute change of venue that moved the student hospitality center from a prime location near the exhibits to a room in another wing of the Phoenix Convention Center, many students’about 70’crowded into the center on opening day. Once there, the Neals offered the visitors an assortment of snacks and an opportunity to participate in an ’icebreakerâ? activity. Professor Tom Sibley of Saint John’s/Saint Benedict’s University in Collegeville, Minnesota, put the students in groups of eight or so, had them clasp one another’s hands at random, and then had them try to maneuver themselves into a simple loop’the not knot. According to Tom, they had about an 80 percent chance of success. For round 2, the students were challenged to link up in a way that would form a real knot. |

In January 2004, at the Joint MAA/AMS Meetings in Phoenix, the MAA Committee on Student Chapters and Undergraduate Experiences in Mathematics sponsored a Contributed Paper Session on

Suggestions for student activities included a discussion by Daniel Wisniewski from DeSales University (dpw2@desales.edu) of the Problem of the Month Contest (open to all university students, faculty and staff) and Student Chapter trips to the National Cryptologic Museum at Fort Meade in Maryland and to the Museum of Science in Boston, Massachusetts.

Betty Mayfield (mayfield@hood.edu) and three of her
students from Hood College described several field trips that they have
taken in and near Washington, D.C., including behind the scenes visits to
mathematical exhibits at the Smithsonian Institute and descriptions of how
some of these places can be visited through virtual field trips. Thomas Sibley of St. John’s University (TSIBLEY@CSBSJU.EDU) demonstrated several enticing activities such as a donut coloring contest and human knots. Cheryl Olsen (clolse@ship.edu) of Shippensburg University gave examples of successful department sponsored outside of class activities including picnics, student seminars and conferences, and career nights. Aaron Trautwein of Carthage College (atrautwein@carthage.edu) described how the mathematics majors have included students from a wider audience in the celebration of Mathematics Awareness Week by using large-scale projects such as the construction of a large tetrahedron and a banner size golden spiral. |

Greg Cicconetti of Muhlenburg College (grego1074@yahoo.com) described his adventures guiding a student through an independent study project for the first time, learning both mathematics related to visualizing images and strategies for engaging students in future projects. Michael Johnson (am2351@exmail.usma.army.mil) and Edgar Rugenstein (at4464@exmail.usma.army.mil) of the United States Military Academy discussed the valuable research experiences their students have had, highlighting strategies for identifying sponsors for student research projects and for showcasing the student’s research. Holly Zullo of Carroll College (hzullo@carroll.edu) shared goals and the nuts and bolts of a mentoring program for undergraduate mathematics, engineering, and computer science majors. Dave Feil of Carroll College (dfeil@cc.edu) showed how the solution to a problem posed to a student problem solving group led to a summer of research with a student into magic squares, a student talk at a Sectional MAA meeting and the submission of a paper. Lisa DeMeyer of Central Michigan University (lisa.demeyer@cmich.edu) discussed the structure of a summer undergraduate research program as well as the problems that her students worked on, their accomplishments, and her reflections on her experiences as a first time advisor for undergraduate research.

Lynn McGrath of the University of San Diego (lmcgrath@sandiego.edu) described how she and colleagues Perla Myers and Jane Friedman worked with undergraduate mathematics majors and future mathematics teachers in a summer mathematics enrichment camp for elementary students. Vince Schielack of Texas A&M University (vinces@math.tamu.edu) described a competition for future teachers of secondary mathematics designed to generate interest in mathematics teaching careers and recognize exemplary students. Natalya Prokhorova of The Alabama School of Math & Science and the University of South Alabama (nprokhorova@asms.net) discussed the South Alabama Math Circles, developed with Vasiliy Prokhorov of the University of South Alabama (prokhoro@jaguar1.usouthal.edu), which engages secondary students in creative problem solving through topics in mathematics that are normally outside of the school curriculum.

CUSAC administers a special MAA fund to help bring students from underrepresented groups to the Joint Mathematics Meetings. Faculty may apply for small (up to $500 per institution) grants to cover the cost of registration, food, lodging, and travel for their students. This year we were pleased to offer travel grants to six colleges and universities to send students to Phoenix’four colleges from California, one from Texas, and one from Georgia. A total of eighteen students from those schools participated in the Joint Meetings, attending the MAA Student Lecture, student reception, and undergraduate poster session as well as many other events. Six of the students presented their work in the poster session. |

Professor Mario Martelli of Claremont McKenna College, the organizer of the undergraduate poster session, wrote for

Meeting of the American Mathematical Society, the Mathematical Association of America, and the Association for Women in Mathematics. Thanks to the efforts of Jim Tattersall, Associate Secretary of the MAA, we were assigned half the Ballroom of the Phoenix Convention Center and we filled it up! Over 115 professional mathematicians participated in the evaluation of the posters, and 32 $100 prizes were given to the posters that received the highest marks. As in past years the prize money came from the AMS, MAA, AWM, and CUR. This year, for the first time, and with welcomed generosity, we received a considerable contribution from the Moore Foundation.â? The two posters that received the highest marks of all were ’A Conjecture on Homogeneous Ideals,â? presented by Melissa Krause of Cal Poly San Luis Obispo (advisor Dr. Ben Richert) and ’Subgraph Summability Number of a Graph,â? presented by Josh Whitney from Arizona State University (advisor Dr. Sivaran Narayan, Central Michigan University). Both projects were done with the REU programs at Cal Poly San Luis Obispo and at Central Michigan University. The complete list of all winning posters, in alphabetical order with no ranking, is available at the MAA website: /news/jmmundergradposter04.html. Mario wrote: ’It has been an incredible and exciting event! Some people said that a lot of merit is mine, but I firmly believe that most of the merit should go to the presenters and to their advisors. Dear friends, presenters, advisors, and judges, I hope to see you all at the Undergraduate Student Poster Session in Atlanta in January 2005!â?

’When Five Colors Sufficeâ?

Joan P. Hutchinson, Macalester College

Friday, August 13, 8:00 pm-9:00 pm

The challenging four-color conjecture, posed in 1852, asks whether four colors are enough to color the regions of any map so that two regions that share a boundary receive different colors. In 1976 K. Appel and W. Haken proved that four colors suffice. With some changes to the problem, four colors may no longer be enough. We discuss these variations in which five, not four, colors suffice.

Mario Martelli, Claremont-McKenna College

Saturday, August 14, 3:00 pm-3:50 pm

In 1429 the architect Filippo Brunelleschi won the competition for building the ’octagonal cupolaâ? of Florence’s cathedral. His innovative design did not use centering. Brunelleschi built a model to show that his proposal would work, but he categorically refused to reveal his secret. The mystery remains today, but a recent mathematical analysis has been able to lift the veil from parts of Brunelleschi’s design. How? Come to the talk to find out.

The Contributed Papers Session sponsored by CUSAC has been approved for the Joint Mathematics Meetings in Atlanta. This session, titled ’Mathematical Experiences for Students Outside the Classroom,â? is being organized by Kay Somers of Moravian College and Jody Sorensen ofGrand Valley State University.

Mathematics "happens" both inside and outside the classroom and, in fact, many mathematics majors are drawn to the subject through a special event sponsored by a Student Chapter or Math Club. This session seeks presentations by academic, industrial, business, and/or student mathematicians so that the audience will be encouraged to organize and run special events for their students.

Descriptions of non-classroom activities could include, but are not limited to, special lectures, workshops for students, Math Days, Math Fairs, research projects for students, Math Career Days, student conferences, recreational mathematics activities, problem solving activities and contests, general community-building activities, and student consulting projects. Information on how such activities are organized and carried out, what activities especially grab students' interests, how students are contacted and encouraged to participate, and how the events are funded will be especially helpful. This session is organized by the MAA Committee on Undergraduate Student Activities and Chapters.

MAA Student Lecturer

The MAA student lecturer at the JMM in Atlanta will be Robin Wilson. It is probable that his topic will be ’The Mathematics of Lewis Carroll.â?
