The centennial meeting of the Iowa Section of the Mathematics Association of America will soon be here. Friday night, we will celebrate the centennial with pizza and birthday cake. (Please contact Sergio Loch if you have special dietary needs, and we will do our best to provide an alternative meal.) Following the celebration, we are fortunate to have Arthur Benjamin performing his "Mathemagics!" show Friday night at 7:30 p.m. There will be two invited talks on Saturday: Stephen Kennedy from the MAA on Saturday morning (time 8:30-9:30 a.m.) and Steve Butler, last year's Iowa Section teaching award winner, on Saturday afternoon.

Arthur Benjamin
Harvey Mudd College


Arthur Benjamin will demonstrate and explain how to mentally add and multiply numbers faster than a calculator, how to figure out the day of the week of any date in history, and other amazing feats of mind. He has presented his mixture of math and magic to audiences all over the world.

Halving Your Cake

It is a problem as old as humanity: given a resource to be shared (water, land, cake) how can it be shared fairly between several people? The answer, in the case of two claimants, is simple and ancient and known to every five-year-old with a sibling: I cut,You choose. Things get much more interesting, and challenging, if one has more than one sibling. We are forced to ask ourselves exactly what “fairly” means in the question; “fair” from whose point of view and by what criteria?

An Introduction to the Mathematics of Juggling

Juggling and mathematics have been done for thousands of years, but the mathematics of juggling is a relatively new field that dates back a few decades and looks at using the tools of mathematics to analyze, connect, and count various juggling patterns. We will introduce some of the very basic results related to the mathematics of juggling with a particular emphasis at looking at the various methods used to describe juggling patterns.

Call for Student and Faculty Papers

As usual, we hope for a wide variety of talks from our own members. If you have something interesting to say about mathematics or teaching, contribute a talk and share with the rest of the section. Students (both undergraduates and graduates) are encouraged to participate.

Proposals for talks are due in September 30. Please use the electronic submission form, if at all possible. (Logging in first will make it easier, so you are encouraged to do so.) If you are unable to use the submission site, please send the following information to Jason Smith:

    Thank you for considering preregistering for the upcoming meeting. This will save you time at the meeting, make it easier for our secretary at the meeting, and increase the efficiency in gathering the data that the MAA headquarters asks of us for each meeting (including gender, whether you are a presenter, and student/faculty/other status). When you come to the registration table at the meeting, indicate that you have already preregistered. Your name will be looked up from the list gathered from this registration tool and you will only need to pay the registration fee ($10) to complete the process. Preregistration takes place here. Note that you can use this page whether you are currently in our database or not (see below), but the process will be much easier if you already are.

    IA section database

    We are trying to maintain an up-to-date database of all section members to provide better communication, save expenses on mailings, and help with the registration and proposal process. If you have not already updated your information, you may do so by using the log in page here. The credentials that you need here are your email and your password. If you forgot your password, you can always have it sent to by using the "I forgot my password" link on the log in page (log in). This assumes that you are in the system. If you are not sure if you are or not, check here. If you are not in the system, use the Contact menu there to send a message to request to be added.
