"What Did You Do Last Summer?" A student panel

Jack Dealtrey '15, Ben Freedman '14, Clare McLaughlin '14, Kim Rich '14, and Cody Stockdale '15, Bucknell mathematics students

Abstract: There are many exciting summer opportunities for students of mathematics. These range from internships in financial companies to pure research experiences, either at Bucknell or at another university. In this week's colloquium, a panel of your peers will tell you about experiences they have had in recent summers. What did they enjoy about their experiences? What did they get out of them? When did they apply? There will also be ample time for questions and answers. These varied opportunities, as well as being terrific fun, are also immensely valuable as you begin to think about your careers after Bucknell. Come and join us for some pizza and lively discussion.

Pizza, calzones, and drinks will be provided. All are welcome!

Jove GrahamOne Thing Leads to Another? The Most Beautiful Equation in Medical Research

Jove Graham, Ph.D., Investigator I and Director, Clinical Research Project Development, Geisinger Health System, Danville, PA

Abstract: Physicians often wish to know whether a medical treatment will have a desirable effect on an individual patient, but for various practical reasons, physicians must base decisions on medical research that reports on average effects in groups of patients. Understanding that distinction, and how average effects are measured, is important in interpreting and evaluating the results of clinical research. Perhaps surprisingly, a simple formula learned in high school algebra class, Y = a + bX, can be used as a starting point for representing and investigating a wide variety of clinical research questions, provided that the user understands what each component of the equation represents and appreciates other study design considerations that must be taken into account. In this colloquium, we will explore the utility of this simple equation and how it can be applied to some examples and common pitfalls in medical research.

MCM 2013Mathematical Modeling Contest 213 Student Panel: How to Bake Better Brownies

Kristina Li '14, Li Li '16, and Rachel Ren '15, Bucknell University

Abstract: "How to bake better brownies" is the question the team of Li, Li, and Ren answered as they embarked in the 96-hour competition, the 2013 Mathematical Contest in Modeling (MCM). For their efforts Kristina, Li, and Rachel earned Meritorious Winner (only 24 out of 5,636 teams placed above them in this year's MCM competition). Kristina, Li and Rachel will explain the three models they developed for baking brownies which take into account thermodynamic and geometric considerations. Based upon the results of their models, the team will give advice on how to bake a better brownie and they will also share their strategies for success in the MCM competition.

Pizza, calzones, and drinks will be provided. All are welcome!

Peter McNamaraThe Art of Double Counting

Peter McNamara, Department of Mathematics, Bucknell University

Abstract: In the world of accounting, double counting can lead to trouble. In the world of combinatorics, however, double counting can lead to great results. We will show off the simplicity and power of double counting using examples that demonstrate the wonder of Pascal's triangle.

Pizza, calzones, and drinks will be provided. All are welcome!

Chiacchio Portrait Sharp lower bounds for eigenvalues of linear and nonlinear Neumann problems

Francesco Chiacchio, Dipartimento di Matematica e Applicazioni "R. Caccioppoli", Università degli Studi di Napoli

Abstract: We prove some sharp lower bounds for the first nontrivial Neumann eigenvalue for the p-Laplace operator in a Lipschitz, bounded domain. Our estimates are asymptotically sharp, at least for n=p=2. In particular we show that equality is achieved along a sequence of rhombi as the acute angle goes to zero.

A Robinson and J. LevisThe Sexiest Job of the 21st Century
or
How Analytics Professionals Make the World Go Round




Anne G. Robinson, Ph.D.,Director Supply Chain Strategy and Analytics, Verizon Wireless
Jack Levis, Director of Process Management, UPS

Download the main slides from the talk or the slides on UPS and Analytics.

Abstract: Math is cool. There is no other way to look at it. It's hard to open a business magazine, walk through an airport or even participate in an executive meeting and not see or hear reference to analytics. Recognized as the currency of business, mathematics or analytics are empowering decision-making at new levels. A trend that started with CIOs is spreading throughout the C-Suite – Everyone wants ANALYTICS!

As a result of this trend, employment opportunities for analytics experts are also prospering. Indeed.com, an online global jobsite, has experienced an increase of over 15,000% in analytics related job postings between 2011 and 2012. McKinsey & Company examined the growing demand for analytics professionals in the U.S. and the shortage of trained people in the field. They predict that demand for deep analytical talent in the U.S. could be 50-60% greater than its supply by 2018. Gartner estimates that only one third of the 4.4 million data scientist roles available worldwide will be filled by 2015. Harvard Business Review calls these jobs The Sexiest Job of the 21st Century!

What exactly are these analytics professionals doing? What types of real-world problems are they solving? Are they actually applying the math, statistics and operations research tools they learned in their courses? What other skills or certifications do they have? Hear from Anne Robinson from Verizon Wireless and Jack Levis from UPS about their own career paths as well as the exciting careers of colleagues they have met along the way!

Mathematics Alumna Presentation on Actuarial Career Path: Wednesday, September 25, 5:00-6:00pm in 266 Olin Science

Cigna logoAre You Interested in the Actuarial Career Path?

Alyssa Ward '12, Cigna

Abstract: Are you interested in the actuarial career path that will allow you to exercise your analytical skills in the business world?
Cigna's mission is "to help the people we serve improve their health, well-being and security" and our actuaries work hard to make sure the company is able to meet and exceed the needs of its customers and shareholders.
Actuaries use their analytical abilities to help manage Cigna's risk with a strong focus on improving business results. A great way to assess whether the actuarial profession in general and Cigna in particular are a good fit for you is to participate in our actuarial summer internship.
Supported by the Mathematics Department and the Career Development Center. Pizza and drinks will be served.

Chiacchio Portrait Rearrangements and spectral inequalities

Francesco Chiacchio, Dipartimento di Matematica e Applicazioni "R. Caccioppoli", Università degli Studi di Napoli

Abstract: We will firstly recall the definitions and the basic properties of the rearrangements. Then we will show how they can be used in order to derive some classical spectral inequalities. In the last part of the talk we will describe some recent results concerning the first non-trivial Neumann eigenvalue of the Hermite operator. We will show for instance that, making use of the "Gaussian rearrangement" it is possible to obtain a Szegö-Weinberger type estimate for such an eigenvalue.

Polynomials and Pirate Gold

Paul McGuire, Department of Mathematics, Bucknell University

Abstract: Given a finite number of points in the plane, there are several ways to find a polynomial passing through the given points.  We will explore a couple of such methods and illustrate how the analog of one method can be used to solve the following fun puzzle associated with the Chinese Remainder Theorem.
Seventeen pirates appropriate a sack of gold coins.  The first attempt to divide the spoils leaves three coins leftover.  In the ensuing brawl, one pirate gets killed.  The next division leaves ten coins.  Another argument ensues and yet another pirate gets killed.  Now the coins divide evenly.  What is the smallest possible number of coins?
Pizza, calzones, and drinks will be provided. All are welcome!
