- Hippocrates and the Quadrature of the Lune

- Speaker
- John Stoughton
- Professor of Mathematics
- Hope College
- Holland, MI

- Abstract: The problem of squaring the circle (i.e., given a circle, can we construct, withstraightedge and compass alone, a square with EXACTLY the same area?) is one ofthe oldest in mathematics. It was proposed sometime before 440 BC (the time ofHippocrates) and was not solved until 1882. Hippocrates came very close toshowing that it could be done and his work led some of the world's bestmathematicians to believe that it could. (It can't.) In this talk, we examineHippocrates' work and discuss why it took over 2300 years from his time for theproblem to be solved.

- Professor of Mathematics
- Hope College
- Holland, MI

- Tim Pennings
- Abstract
- A standard calculus modeling problem is to find the quickest path from a point on shore to a point in a lake, given that running speed is greater than swimming speed. Elvis, my Welsh Corgi, has never had a calculus course. But when we play "fetch" on the shore of Lake Michigan, he appears to choose paths close to the optimal one. In this talk we reveal what was found when we experimentally tested this ability. Elvis will be available for follow-up questions.

- Peter Bates
- Abstract
- Starting with some fundamental assumptions about the nature of materials, we willformulate laws governing the evolution of material states (such as differingphases, local magnetic orientation, etc.). These laws become equations ofevolution. We will then try to determine the qualitative behavior of solutionsor look at special wave-like solutions and in so doing generate good mathematicsand (I hope) good science.

- Speaker
- Giovanni Dimatteo
- Junior Mathematics Major - Track I
- Deparment of Mathematics and Computer ScienceAlbion College
- Albion, MI

- Giovanni Dimatteo
- Abstract
- Ramsey theory is the study of the structures on a mathematical object that are preserved under partitions. In this talk, we'll examine the Party problem, solve it, and discuss generalizations, closing up with Ramsey's theorem. An example of the party problem asks, 'how many people must you invite to your party to ensure that there exists a group of 4 mutual friends or a group of 4 mutual strangers.' Applications to computer science and other fields will be discussed, along with the statement of several research problems on which undergraduates are capable of making progress.

- Phosphorus Contamination in Lake Sediments: Model and Solution

- Speaker
- Gilbert N. Lewis
- Associate Professor
- Department of Mathematics
- Michigan Technological University
- Houghton, MI

- Gilbert N. Lewis
- Abstract
- Phosphorus is a contaminant that can enter a lake due to natural or human activity (effluent from a wastewater treatment plant, non-point runoff from farmlands, etc.). Once in the lake, it may enter the sediments at the bottom of the lake, where it is stored and becomes availableas a further source of contamination to the lake waters. In this study, wemodel the deposition of phosphorus in the solid phase to lake sediments, the subsequent conversion (diagenesis) to a liquid form, and the diffusion of the liquid phase phosphorus back into the lake water. We develop a system of twopartial differential equations involving two dependent variables (solid and liquid phosphorus concentrations) and two independent variables (time and depth in the sediment). We then show the numerical solution of the system and compare it with observed data. The ultimate goal is to be able to accurately predict future rates of release of phosphorus from the lake sediments if restrictions are placed on the level of human input to the system.

- Beauty at the Extreme: The Hunt for Extremal Graphs

- Speaker
- Jason Williford
- Visiting Assistant Professor of Mathematics
- Albion College

- Abstract
- In this talk we will explore the relatively young field of Extremal Graph Theory. One of the first results in this field answers the following question: how many edges can a graph with n vertices have if it has no complete graph of size k as a subgraph? Since the solution of this problem in the 1940's there have been many generalizations; however overall little is known. One of the main reasons for the lack of knowledge stems from the fact that graphs with certain properties are often hard to construct. Examples of certain known constructions will be given, and possibilities for undergraduate research projects will be discussed.

- Three Cool Linear Algebra Applications from the Sciences

- Speaker
- Mark Hanisch
- Associate Professor of Mathematics
- Calvin College
- Grand Rapids, MI

- Mark Hanisch
- Abstract
- Polling recent mathematics graduates might lead oneto conclude that Markov processes, curve fitting, andsystems of ODEs are the main applications for linearalgebra. But thanks to the simplicity of linear models,one does not have to look hard to find solutions to manyother applied problems that employ linear algebra in asignificant way. In this talk I will outline three morescience problems, the physics of spinning objects,"dimensional analysis", and the spectroscopic examinationof chemical solutions, for which fundamental ideas fromlinear algebra provide amazing clarity.

- Group Actions on Curves

- Speaker
- Darren B. Glass
- VIGRE/Ritt Assistant Professor
- Department of Mathematics
- Columbia University
- New York, NY

- Darren B. Glass
- Abstract
- Algebraic Geometry is the study of curves which are defined by polynomial equations. Some of these curves have special properties, such as the existence of a group action on the curve. These group actions correspond to nice symmetries in the curve, and are useful in calculating certain invariants. This talk will define all of these terms, and give many examples of such actions. In particular, we will look at the elliptic curves which were recently made famous in the proof of Fermat's Last Theorem, and generalizations such as the hyperelliptic and superelliptic curves.

- Anonymous Credentials with Biometrically-Enforced Non-Transferability: Designing Hand Stamps for the Digital World

- Speaker
- Sara Miner More
- Faculty Fellow Professor
- School of Computer Science and Engineering
- University of California - San Diego

- Sara Miner More
- Abstract
- Digital non-transferable anonymous credentials allow individuals in aparticular group to remain anonymous while demonstrating group membership.An analogous credential in the real world is a hand stamp one mightobtain upon entering an establishment that serves alcohol, afterdemonstrating that he is of legal drinking age. The individual later useshis stamp to prove to the bartender that he is old enough to purchasealcohol, but the stamp alone does not reveal the individual's identity.Furthermore, this credential cannot be transferred to a differentindividual. In this talk, we address the challenges of achieving this type ofcredential in the digital world, and present a solution based oncryptography and secure hardware. No prior knowledge of cryptography orsecurity is required. This talk describes joint work with RussellImpagliazzo from UCSD.

- The Physics of Hard Problems

- Speaker
- Harold Connamacher
- Doctoral Candidate
- Department of Computer Science
- University of Toronto

- Harold Connamacher
- Abstract
- A large number of problems we deal with in computer science are considered hard. One such problem is the Satisfiability Problem (SAT). Despite years of work, no one has developed algorithms for SAT that can solve all possible instances in a reasonable amount of time. In fact, most researchers do not believe any such algorithm exists. In practice, SAT-solvers are either complete solvers that always solve the problem and sometimes run in a reasonable amount of time or incomplete solvers that always run in a reasonable amount of time and sometimes solve the problem.
- Recently, a group of physicists have applied techniques of statistical mechanics to problems such as SAT to gain more insight into why the problems are hard. As part of their work, they have proposed a new algorithm called Survey Propagation that seems to work better than other current incomplete solvers.
- This talk will highlight the current state of the research and expose reasons why this new algorithm works well and reasons why it may fail in some important situations.

- Sums-of-Squares Formulas

- Speaker
- Daniel Isaksen
- Assistant Professor
- Department of Mathematics
- Wayne State University
- Detroit, MI

- Daniel Isaksen
- Abstract
- Consider the polynomial identity
- (x12 +x22 )(y12 + y22) = (x1y1 - x2y2)2+ (x1y2 + x2y1)2

- This formula might be generalized as
- (x12 + ... + xr2)(y12 + ... + ys2) = z12 + ... + zn2

- where each zi is "bilinear" in the x's and y's in the sense that it is a sum of monomials of the form c (xi yk). These identities are relevant to questions about normed algebras, embeddings of topological spaces, and linear algebra.
- We'll find a few examples of such identities, but the problem of finding this type of identity is extremely difficult. It turns out to be easier to show that identities cannot exist under certain circumstances.

- Ryan McFall
- Abstract
- Electronic textbooks are an enticing idea. Most publishers tout digitalmedia as a cheaper and more portable textbook. Unfortunately, theelectronic textbook models that have been proposed too often seek to mimicthe paper textbook, perhaps adding search capabilities or touting thepossibility of interactive animations and activities. These electronictextbooks fail to take full advantage of the pedagogical opportunities thata digital medium provides.
- This talk will outline the design goals and features of an electronictextbook application designed at Hope College with the goal of extending,rather than simply mimicking, a traditional textbook. In particular, wewill discuss how an electronic textbook can be used to bring the idea ofcollaborative learning into the textbook reading experience, and how such atextbook can be used to facilitate change in the way the classroomexperience is conducted.

- Abstract
- Supercell thunderstorms are intense, long-lived rotating thunderstormswhich rumble across the heartland of the United States every spring.Because supercells produce the strongest tornadoes, their behavior isa focus of active research. Meteorologists have yet to answer suchfundamental questions such as: How do tornadoes form within a supercell?Why do some supercells produce devastating tornadoes while other do notproduce a tornado at all? The two primary approaches to this problemare observation (including storm chasing) and numerical modeling. I amtaking the modeling approach to investigate the internal workings ofsupercells. In this talk I will present an overview of the predictivemathematical equations which describe the behavior of the atmosphere,how 3D atmospheric models work (with some discussion of parallelprocessing), and the challenges of taking terabytes of binary modeldata and visualizing it in a human-intuitive way.
