“An Orchestra without a Conductor: The Mathematics of Synchronizing Fireflies” at noon on Thursday 2/28 in Olin 268

Student Colloquium talk by Professor Matthew Mizuhara ’12 of The College of New Jersey Title: An Orchestra without a Conductor: The Mathematics of Synchronizing Fireflies Abstract: In Amphawa, Thailand trees are lined with thousands of fireflies spontaneously flashing in near perfect unison. However, there is no “leader” driving this coordination. The Kuramoto model, a non-linear system of differential equations, describes the firefly flashes. Using numerical simulations, we can capture this spontaneous emergence of synchronization and explore other, new patterns which can arise. No background in differential equations is required to enjoy this talk!

Sports, Statistics and Society

As part of Professor Flynt’s Foundation Seminar titled Sports, Statistics and Society, groups of first-year students acted as consultants, performing sports analytics for different Bucknell athletic teams.  Students worked with Baseball, Field Hockey, Men’s and Women’s Basketball, and Football.  Each coach developed a set of questions that they were interested in having the students analyze and gave students full access to their team data.   The group of students working with the football team worked very closely with Offensive Coordinator, Coach Bobby Acosta, spending time in the football coaching suite, looking at game video, and taking stats for the team up in […]

Assigning Students to Schools to Minimize Socioeconomic Variation between Schools: An Introduction to Optimization Modeling at noon on Thursday 10/18 in Olin 268

Student Colloquium talk by Professor Dick Forrester of Dickinson College Title: Assigning Students to Schools to Minimize Socioeconomic Variation between Schools: An Introduction to Optimization Modeling Abstract: Numerous studies have found that a student’s academic achievement is as much determined by the socioeconomic composition of their school as their own socioeconomic status. In this talk we provide a methodology for assigning students to schools so as to balance the socioeconomic compositions of the schools while taking into consideration the total travel distance. Our technique utilizes a bi-objective general 0-1 fractional program that is linearized into a mixed 0-1 linear program which can […]

Student talk: Tom Cooney October 19, noon in Olin 268

Quantum Games and Quantum Computing Thursday, October 19, 12:00 P.M. ROOM 268 in the Olin Science Building Abstract: What’s the shortest message you can send someone? It might seem like the answer is a single bit: a 0 or a 1. But the world is much stranger than that! We can also send quantum bits (or qubits) that can be 0 or 1 or “both” 0 and 1 at the same time. These quantum messages have surprising power for computing and sending information. I’ll talk about how we can better understand these strange quantum messages by studying games that use […]

Fibonacci at Bucknell!

Leonardo of Pisa (a.k.a Fibonacci) has a remarkable connection with Bucknell, and to celebrate this fact we are holding an interdisciplinary conference on October 14. Featured speakers include: Mario Livio – an astrophysicist and author of popular science books, Keith Devlin – NPR’s “Math Guy” and the author of numerous popular mathematics books, William Goetzmann – Director of the International Center for Finance, Yale University This event will be in the Langone Center from 10:00 a.m. until 2:30 p.m. Lunch tickets are available in Olin 380, or by writing to math@bucknell.edu Learn more here.

Student Talk: Jimmy Chen, September 21 at noon in Olin 268

Title: Efficiency Of Non-Compliance Chargeback Mechanisms In Retail Supply Chains Abstract: In practice, suppliers fill retailers’ purchase orders to the fill-rate targets to avoid the non-compliance financial penalty, or chargeback, in the presence of service level agreement. Two chargeback mechanisms – flat-fee and linear – have been proven to effectively coordinate the supply chain in a single-period setting. However, the mechanisms’ efficiency, the incurred penalty costs necessary to coordinate the supply chain, have not been studied yet. Since retailers are often accused of treating chargeback as an additional source of revenue, this study compares the expected penalties resulted from the […]

Distinguished Visiting Professor Talk: Il Bong Jung 2/28 @ 4 pm in Olin 372

Title:  Quasinormality and weak quasinormality of operators   Abstract:  There are two notions to define the quasinormality of unbounded operators by Kaufman and Stochel-Szafraniec respectively. Our results show that Kaufman’s definition of an unbounded quasinormal operator coincides with that given by Stochel-Szafraniec. In this talk we discuss various characterizations of unbounded quasinormal operators. Examples demonstrating the sharpness of our results are constructed. An absolute continuity approach to quasinormality which relates the operator in question to the spectral measure of its modulus is developed. This approach establishes a new definition to be called weakly quasinormal operators. Some characterizations concerning to the […]

Distinguished Visiting Professor Talk: Ralf Schmidt 1/31 @ 4 pm in Olin 372

Title: What is Number Theory? Abstract: In its original meaning, Number Theory is concerned with the properties of the “natural” numbers 1, 2, 3, … In this talk we will attempt to explain how the consequent study of “elementary” properties of numbers leads naturally to the theory of automorphic forms and the vast web of conjectures known as the “Langlands program”.
