February 7  Welcome Back Tea Party 4:30 in King 203 
Please join us, and please invite anyone having an interest in Mathematics! 
March 13  Student/Faculty Luncheon "Squooshing the Cube" Kevin Woods  Department of Mathematics 12:15  Wilder 115 
Challenge: take a cardboard box and squoosh it (please take the cereal out first, and glue the lid back closed). Okay, too easy  a good stomp with a snow boot will flatten it. A Harder Challenge: squoosh the cardboard box, but at the same time make its volume bigger. I'll talk about this and other topics related to folding cubes and other polyhedra. 
April 2  Candidate Lecture “Arctangent Identities for Pi” Jack Calcut 4:30 in King 243 
Is there a better identity for pi than pi=4arctan(1)? Are the degree angle measures ever rational in a triangle whose side lengths form a Pythagorean triple? Which regular polygons may be built on a geoboard? The answers to these questions are intimately related to arctangent identities for pi, which we will explore using the number theory of the Gaussian integers. We will present some of the historical context as well as some directions for further research. 
April 7  Prospective Majors Meeting 4:30 in King 203 
If you are interested in perhaps pursuing a mathematics major, you are invited to this meeting. Refreshments will be served and any questions you have about the majors will be answered. 
April 9  Lecture “ Dealing With Ups and Downs: Functions of Bounded Variation ” Pamela Pierce  The College of Wooster 4:30 in King 241 
Intuitively, the variation of a function f on [a,b] is a measure of how much the yvalues of the function “vary” over the interval [a,b]. In effect, we are isolating the vertical component of arc length of the graph of f. After providing a precise definition of the total variation of f on [a, b], we will consider those functions whose total variations finite on [a,b] and call this class of functions BV. We will look at several examples of such functions, explore the properties of the class BV, and discuss some extensions of this concept. 
April 10  Candidate Lecture “Polynomials Built Using Fibonacci Numbers” Donald Mills  Illinois State University 12:20 in King 243 

April 17  Student/Faculty Luncheon "SledgeHammer Integration" Michael Henle  Department of Mathematics 12:15  Wilder 115 
Have you ever been so irritated with an integration problem that you wanted to hit it with a hammer? Come to the Mathematics Department's Pizza Lunch and learn how to do it right, how to crush unfriendly integrals using the trapezoid rule, and other numerical devices, as sledgehammers. 
April 18  Candidate Lecture “Shift Operators ” Michael Raney  Georgetown University 4:30 in King 243 
The theory of bounded linear operators may be viewed as a generalization of linear algebra (matrices and linear transformations) to the setting of infinitedimensional vector spaces (in particular Hilbert spaces). Shifts and backward shifts serve as crucial examples of bounded linear operators defined on Hilbert spaces. In this talk fundamental properties shared by such operators will be presented. We will see that, just as a matrix has a spectrum of eigenvalues, a shift operator also has a spectrum, albeit of a slightly different flavor. 
April 24  Lecture "A Whirlwind Tour of Fractional Graph Theory" Daniel Ullman  George Washington University 4:30 in King 239 

April 28  Candidate Lecture “Sparse Signal Representation Using Multiscale Analysis” WangQ Lim  Lehigh University 4:30 in King 243 
In 1807, Joseph Fourier discovered that he could superpose sines and 
May 1  Honors Lecture “ Additive Combinatorics and Geometry: GradeSchool Math Revisited ” Noah Forman 4:30 in King 239 
A tour of the mathematics that you might have accomplished in grade school, if only you had been many times brighter. We will add numbers, sets of numbers, and shapes. This talk is unofficially sponsored by Milk and Cookies.
