# News and Upcoming Events

April is mathematics awareness month (MAM). The theme for 2014 is Mathematics, Magic, & Mystery. The MAM organization is also celebrating the centennial birth year of Martin Gardner. There are 30 days of theme related activities as well as essays and other things located at http://www.mathaware.org/mam/2014/.

**"Monte Carlo: Real World Benefits & Challenges for
Actuarial Models"**.

As the title suggests, the presentation will discuss the use of
Monte Carlo models in real world actuarial applications. Most
actuarial models in practice are deterministic. Use of a Monte
Carlo approach is fairly limited; such models are generally
employed for risk analyses, such as assessing the distribution of
outcomes over a one year time horizon. While those applications are
fitting, Monte Carlo models can also be used in place of
traditional deterministic models. In this presentation, we will
walk through basic examples of deterministic actuarial models,
discuss their usage, and identify certain shortcomings. We will
then explore how a Monte Carlo model can overcome such limitations.
The story of Monte Carlo models is not entirely rosy, though.
Hence, we will also discuss some of the challenges they face in the
real world.

Please join us **Friday, April 18, 2014 at 4:00 pm in
Jordan Hall Room 236**. Refreshments will be

**Butler Senior Seminar Students**

Monday, April 28 at 3:30 p.m. in Jordan Hall Room 242

Join us as our Senior Seminar students present on a variety of mathematical concepts that they have studied during their time in the course this spring.

**Undergraduate Research Conference April 11, 2014**

Aaron Schlenker presented the results of his research at the URC on April 11, 2014. A mathematics and computer science major, Aaron's research was titled Generalized Mandelbrot Sets and Their Algorithms.

**Previous Mathematics & Actuarial Science
Colloquium Speakers**

**Butler University Senior Actuarial Science Majors
** Friday, January 31 at 2:30 p.m. in Jordan Hall Room
236

Senior actuarial science majors described how they landed awesome summer internships, as well as what those internships had them work on. This was the third annual internship colloquium and is always one of the favorites of our actuarial science majors.

**Dr. Scott Chapman,editor of the American Mathematical
Monthly
** Wednesday, October 23rd

The American Mathematical Monthly is the mostly widely read math journal in the world, and Dr. Chapman is a renowned mathematician, a professor, and Scholar in Residence at Sam Houston State University. He specializes in modern algebra.

**Amanda Harsy Ramsey,**PhD student at IUPUI and newest adjust faculty member of the Mathematics and Actuarial Science Department at Butler University

Friday, November 15th

What if we could take a pumpkin, cut it up into finitely many pieces, and then reassemble the pieces so that we get two pumpkins identical to our first pumpkin? We could make a lot of pumpkin pie. In this talk, we will introduce and explore properties of Free Groups which have this counter-intuitive property. Free groups are one of the most commonly used groups in Geometric Group Theory, an exciting, relative new area of mathematical research in which we treat groups like geometric objects. In particular, we will discuss the relationship of free groups to The Banach Tarski paradox, amenability, and Yu's Property A.

**J. James Woods Lectures in the Sciences and
Mathematics
**

**Dr. Carl Pomerance**spoke on

**"What We Still Don't Know About Addition and Multiplication"**on Tuesday, December 3.

How could there be something we don't know about arithmetic? It would seem that subject was sewn up in the third grade. But here's an answer we don't have: What is the most efficient method for multiplication? Another: How many different numbers appear in a large multiplication table? Come hear about many more of these types of problems, plus some recent progress.

Pomerance, a number theorist, specializes in analytic, combinatorial, and computational number theory, with applications in the field of cryptology.

**Butler Senior Seminar Students** spoke on Friday,
December 13th, presenting a variety of mathematical concepts.

**The Department Fall Picnic
2014**

**The Department Fall Picnic 2014**

The department hosted the annual student/faculty picnic for all majors at Professor Duane Leatherman's residence in Resco "D" Unit. A large group of students and faculty met for a delicious dinner, great conversation, and fun outside Prof. Leatherman's front door between Photos are available at Prof. Leatherman's website http://blue.butler.edu/~dleather/fir/unitD/events10/mathdinner.html

### MAA Scavenger Hunt 2014

The MAA student chapter hosted its annual scavenger hunt for high school teams on March 1, 2014. The event concludes at approximately 12:30-1:00 p.m. after prizes are awarded. Lunch was included for all attendees.

The event was an exciting morning with high school teams competing for prizes as they hunted for the solutions to mathematical problems. Each teamwss led by a Butler student member of the Mathematical Association of America club. For more information concerning the 2015 MAA Scavenger Hunt, please contact Rena Duerksen (mailto:rduerkse@butler.edu) or Professor Kathie Freed(mailto:kfreed@butler.ed
