“Curing Cancer: Mathematicians Want a Piece of That!” at noon on Thursday 2/27 in Olin 268

Student Colloquium Talk by Professor Allison Lewis, Lafayette College Abstract: How can mathematical modeling assist in the development of treatment protocols for cancer? Recent technological advances make it possible to collect detailed information about tumors, and yet clinical assessments of treatment responses are typically based on extremely sparse datasets. We propose a workflow for choosing an appropriate model for tumor growth and treatment response, verifying parameter identifiability, and assessing the amount of data necessary to precisely calibrate model parameters in order to make accurate predictions of tumor size at future times. Throughout this talk, we will discuss ways in which […]

“Factoring Rook Polynomials” at noon on Thursday 2/13 in Olin 268

Student Colloquium Talk by Professor Kenny Barrese, Bucknell University Abstract: Rook theory is a branch of mathematics which considers how many ways you can put rooks on a board so that no two are attacking each other. Here a “rook” is the usual chess piece, but the “board” that we are placing on probably is not an eight by eight square. One way to consider the numbers you obtain is as coefficients of a polynomial, the rook polynomial. It is a key result in rook theory that, if you define the rook polynomial correctly, it always factors completely! In fact, […]

“A Basic Overview of the Actuarial Profession” at noon on Thursday 1/30 in Olin 268

Student Colloquium Talk by Gloria Asare, AXA Insurance, Toronto, Canada Abstract: Come learn what it takes to become fully certified and work as an actuary. Our presenter Gloria Asare, ACAS, MAAA will touch on various topics of interest related to the actuarial field. These include: how to become an actuary; the different types of actuaries that exist; the types of mathematical problems actuaries solve; what one’s journey to being an actuary could look like; and diversity in the actuarial profession. Anyone interested in the actuarial profession (even if you don’t know what it is) is welcome! A mathematical background is […]

“From the Bridges of Königsberg to Data Analysis” at noon on Thursday 11/21 in Olin 268

Student Colloquium talk by Professor Chris Johnson, Bucknell University Abstract:  The Prussian city of Königsberg once contained four land masses connected by a series of bridges, and citizens of the city would sometimes ponder the following simple puzzle: is it possible to walk through the city crossing each bridge exactly once?  In analyzing this question, Leonhard Euler noted that the most important feature was how the bridges connected the land masses to one another.  Understanding “connectedness” is one part of a branch of mathematics called topology, and in this talk I will give an overview of a few particular topological […]

“Archimedes’ Cattle Problem” at noon on Thursday 10/24 in Olin 268

Student Colloquium talk by Professor Krishnan (Ravi) Shankar, University of Oklahoma Title:  Archimedes’ Cattle Problem Abstract:  Back in antiquity Archimedes devised a mathematical problem in the form of 22 elegiac couplets and delivered them to Eratosthenes of Cyrene (as a challenge of sorts). The problem is in three parts of increasing difficulty and the solution is rather astonishing, both for its complexity and for the problem’s ability to anticipate mathematics that didn’t come about for 2000 years (Pell’s equation). We will explore the problem and its solution (which was only completely solved in 1889 by Amthor) and ask ourselves the […]

“Understanding Statistical Significance” at noon on Thursday 9/19 in Olin 268

Student Colloquium talk by Professor Kari Lock Morgan, Penn State University Title: Understanding Statistical Significance Abstract:  You may or may not have heard of results being “statistically significant,” and you may or may not know that results qualify as statistically significant if the p-value falls below a given threshold.  Regardless of whether these phrases currently hold any meaning for you, the goal of this talk will be to shed light on the actual meaning of a p-value and statistical significance (beyond just “p < 0.05”).  This will be accomplished by covering a modern and computationally intensive way of computing a p-value […]

“Interacting with the Shadow of Data” at noon on Thursday 9/5 in Olin 268

Student Colloquium talk by Professor J.T. Fry, Bucknell University Title: Interacting with the Shadow of Data Abstract:  In our first statistics class, we learn how to build a scatterplot to visualize two variables at once. But what happens when we have many variables? Projection methods such as Principal Component Analysis (PCA) can create 2D pictures of higher-dimensional data, much like how the sun projects our 3D body into a 2D shadow. However, exploring these high-dimensional datasets can be complicated. In this talk, we present a visual analytics model that allows the user to combine their personal knowledge with a projection method to find novel […]

“Problems and Pipelines: A story from the frontline of data science” at noon on Thursday 4/25 in Olin 268

  Student Colloquium talk by Professor Patrick McDonald, New College of Florida Title: Problems and Pipelines: A story from the frontline of data science Abstract: Suppose you were to suddenly obtain access to a remarkably rich data source, say, a trove of health records. What would you do? In this talk I will sketch how a group at New College handled such a situation. In so doing I will provide you with a glimpse of what it is like to work on a large-scale data science project, paying special attention to the vast array of required skill sets, social constraints and behavior […]

“The Dynamics of Continued Fractions” at noon on Thursday 4/11 in Olin 268

Student Colloquium talk by Professor Daniel Visscher, Ithaca College Title: The Dynamics of Continued Fractions Abstract: While only rational numbers have a fraction representation, all real numbers have a continued fraction representation. Continued fractions illuminate interesting structure in real numbers, for example, by giving a way to express how close a real number is to being rational. In this talk, we investigate continued fractions from the point of view of a dynamicist, framing the topic in terms of iterating a function and asking questions about how orbits distribute. Multiple flavors of π will be present, and the golden ratio will make approximately 1.618 appearances.
