Title: A Travelogue of the Mathematical Universe
Speaker:David A. Reimann
Professor
Mathematics and Computer Science
Albion College
Albion, MI
Abstract: Mathematics is all around us, yet can be very abstract. The goal of mathematical art is to create artistic examples of mathematical concepts that can inspire and inform us, or to use mathematical concepts to artistically tell a story. In this talk we will discuss a variety of mathematical concepts and view related mathematical artworks. Hopefully you will leave knowing a little more mathematics, and inspired to further explore the mathematical universe and create your own mathematical art travelogue!

Title: Finding the Best Way From Here to There: A Primer on Variational Calculus
Speaker:Darren Mason
Professor
Mathematics & Computer Science
Albion College
Albion, MI
Abstract: Given a task to accomplish, it is natural to ask what is the best way to achieve your goal? Maybe you are flying from Beijing to London and need the shortest flight path. Or you are selling fuel and you want to find the optimal time $t$ to sell it so that you can maximize your profit. Or you are crossing a river with a strong current and want to determine a propeller direction (as a function of time) so that you cross the river in the least amount of time. The number of possible questions of this type seems endless. During this lecture we will discuss some of the above problems, a famous brain-teaser called the brachistochrone problem, and illustrate how to find solutions to these problems using a version of calculus that makes sense in infinite dimensions — the interesting field of variational calculus!

Title: Abstractions and Single Responsibility: Breaking Apart Problems
Speaker:Culver Ganem-Redd '11
Software Engineer II
Camtasia team
TechSmith Corporation
Okemos, Michigan
Abstract: The ability to break apart a problem into smaller pieces is a key skill to learn when writing code, as well as in many other fields. In software engineering, we often think of this process in terms of "layers of abstraction" and "responsibilities". In this talk, I will explain why thinking in abstractions can be so important, introduce the Single Responsibility Principle, show some examples of how we tend to approach abstractions at TechSmith, and offer suggestions on how to apply this kind of thinking in other fields.

Title: A Difference Equation Approach to Finite Differences of Polynomials
Speaker:Michael A. Jones
Managing Editor, AMS|Mathematical Reviews and Editor, MAA Mathematics Magazine
Ann Arbor, MI
Abstract: First, I will explain why the $\left(n+1\right)$st difference sequence is zero for sequence data generated by an $n$th degree polynomial. Then, I will use difference equations to show that if a sequence has its $(n+1)\text{st}$ difference sequence equal to zero, and $n+0$ is the smallest such integer, then a polynomial of degree $n$ can generate the sequential data. The difference equation approach is new. But, more can be said about the polynomial; I will review others' results on how to construct the polynomial.

Title: My favorite theorem in fiction: the first incompleteness theorem.
Speaker:Andrew-David Bjork
Associate Professor
Mathematics
Siena Heights University
Adrian, Michigan
Abstract: Many authors have incorporated mathematics into their writings. Few have done so as intentionally as Neal Stephenson. His novel Cryptonomicon, published in 1999, holds one of my favorite narrations of Gödel's celebrated result. This talk will follow and explain Stephenson's treatment of the first incompleteness theorem. I will also invite a conversation on the liberal arts today, and why we care so deeply about more than mathematics.

Title: Qubits Versus Plinko: Two Approaches Toward Quantum Computational Supremacy
Speaker:Dr. Tim Rambo `09
Quantum Opus LLC
Novi, MI
Abstract: Quantum Computing sits at the intersection of computer science, physics, and engineering and it's proponents promise a new, more powerful, class of computers. The field is being driven by research at a diverse array of universities, major corporations such as Google and IBM, and startup companies like ours, with the goal of demonstrating a computer that relies on the oddities of quantum physics to solve problems faster than a classical computer. I will discuss why quantum computers are thought to have such great potential, provide a brief introduction to how and why they function differently from classical computers, and look at two different approaches to proving "Quantum Supremacy".

Title: Symmetry Groups: The mathematical connection between patterns in Moorish architecture and the artwork of M.C. Escher
Speaker:David A. Reimann
Associate Professor
Mathematics and Computer Science
Albion College
Albion, Michigan
Abstract: The mathematical structure of symmetrical patterns can be studied using group theory. The Moors built many magnificent buildings richly decorated with geometric patterns during their rule of the Iberian peninsula (711-1492). The graphic artist M.C. Escher visited southern Spain in 1922 and was captivated by the patterns that richly decorate the architecture of the Alhambra, Alcazar, and other Moorish buildings. After a second visit to Spain in 1935, Escher became obsessed with creating patterns of interlocking figures based on these elaborate tiling patterns. While Escher had no formal mathematical training, he used mathematical methods grounded in scientific literature to study these patterns. We will view these patterns through the lens of group theory, one of the great mathematical accomplishments of the 19th century. This talk will be highly visual with many pictures of Escher's works and Moorish architecture.

Title: Stories in Mathematics: Mathematical journeys and what it means to do mathematics
Speaker:Chris Creighton
Ph.D. Candidate
Department of Mathematics
Purdue University
West Lafayette, IN
Abstract: We all do mathematics, but questions arise about who are encouraged and what really is doing mathematics? My hope is to get you to think about the stories you are implicitly telling about mathematics and frame it in a positive light. I will begin with my story from Albion College to my Ph.D. at Purdue University and how I became interested in this work. We will then discuss how words and mathematics are used to encourage and discourage people from mathematics and other societal programs and ending on a discussion of doing mathematics using an example from differential equations. Mathematics is a cornerstone of the Liberal Arts education, bridging between science and the humanities, so we must do our best to encourage all to see the values of mathematics.

Title: Computationally efficient order identification for models of big time series data
Speaker:Brian Wu
PhD Candidate
Mathematics & Statistics
Oakland University
Rochester, Michigan
Abstract: Big time series data with tens of thousands of time points involve complex statistical modeling. Minimizing Information Criteria (IC), such as AIC, AICC or BIC, is used for model order identification. However, this identification process is computationally intensive for big time series because it depends on the repeated computation of the likelihood function. We propose a computationally efficient IC optimization method based on fast kriging surrogates. First, we apply the method to ARMA models with two orders, then we expand it to seasonal time series models of higher dimensional order space. To demonstrate this method, we analyze the results from both simulated and real big time series data related to appliances energy consumption. The method proposed can speed up the order identification process, but its accuracy and computing time depend on the number of fitted time series models needed for the IC optimization.
