Title of Talk: Revisiting What Euler and the Bernoullis Knew About Convergent Infinite Series
Abstract: All too often in first-year calculus classes, conversations about infinite series stop with discussions about convergence or divergence. Such interactions are, unfortunately, not often illuminating or intriguing. Interestingly enough, Jacob and Johann Bernoulli and Leonhard Euler (and their contemporaries in the early 18th century) knew quite a bit about how to find the *exact* values of numerous families of convergent infinite series. In this talk, I will show two sets of *exact* results in this vein. The talk will be accessible to anyone interested in mathematics.

Title of Talk: Explicit Constructions of Functions whose Graphs are Dense in The Plane
Abstract: A set D is dense in the plane if and only if every open ball in the plane contains an element of D. We prove that there exists a function f from the real line R to itself whose graph is dense in the plane by explicitly constructing it using a partition of the rationals into countably many subsets dense in R. We then use this method of construction to prove that there are 2^(2^\aleph_0) functions whose graphs are dense in the plane, and that there exists a function f: R ->R such that f(U) = R for every non-empty open set U in R.

Title of Talk: A Model of Invertebrate Richness on Restored Prairies
Abstract: We will present a differential equations model of prairie restoration. Here, species richness is considered as an indicator of prairie restoration, with the variables for the equation being invertebrate and plant species richness and time. We will incorporate field work from a prairie in Nebraska as an example of our model. Our main goal is determining if planting fewer seeds will yield similar invertebrate richness as planting more seeds, that is, a more cost effective approach.

Title of Talk: Getting Students to Read a Linear Algebra Text--Methods and Reactions
Abstract: Linear algebra may be the first undergraduate course in which is it crucial for students to understand definitions, theorems, and special examples. Exposing students to new material for the first time in class can take up a lot of time and prevent other, deeper material from being covered. This talk will focus on how I have gotten students to write and think about new material that they read on their own, how I have responded to them, and how students have reacted to the experience.

Title of Talk: Toward an integrative model of suction feeding using the immersed boundary method
Abstract: Suction feeding is among the most common forms of aquatic prey capture. During a suction feeding strike a fish rapidly opens its mouth creating a fluid flow that draws in the prey. This is an example of indirect prey capture; the fish does not directly manipulate the prey, but rather the fluid flow around the prey. Previous studies of suction feeding have either studied jaw mechanics or the flow field in isolation, or have only considered rigid jaw motions (think of a fish mouth as a collection of metal plates). In this talk I will describe work in progress to develop a new methodology to study fish suction feeding that relaxes some of these conditions. In particular we will allow for more realistic flexible jaws and examine how the kinematics of the jaw motion affects the resultant flow field and subsequent prey capture.

Title of Talk: Just Plane Numbers
Abstract: The vocabulary of a typical introduction to complex numbers challenges the beginner with a bewildering array of words with strong connotations of "imaginary," "complex," and "non-real." By combining a geometric approach to complex arithmetic found in Roger Penrose's book "The Road to Reality" with the interactive geometry package, Geogebra, we show that it is possible and even insightful to characterize these as just plane numbers.

Title of Talk: Beautiful Strings
Abstract: Let S and T be strings. S is more beautiful than T if (i) S is longer than T, or (ii) if S and T have the same length, then S > T lexicographically. S derives T, if T is a subsequence (not necessarily a substring) of S. T is unique if each character in T appears exactly once. The "Beautiful Strings Problem" is to find the most beautiful unique string that can be derived from a given string S. This problem appeared on the web and in at least one programming contest last year, with no correct solution known to this author. We give an efficient solution, showing the usefulness of a mathematical approach.
