Bucknell Mathematics Student Colloquium Series Thurs, Sept. 15 | Noon-12:50PM | Olin 268 Using Maths to Save The Worldpresented by Helen Greatrex, Professor of Geography and Statistics, Penn State University ABSTRACT: Droughts kill thousands of people each year, especially in countries like Somalia where there is conflict and very little water to start off with. Humanitarian experts often have to decide which places need the most help and alongside working with local communities, they also have to know how much rain has fallen. But how do you map rainfall in places where it’s too dangerous to gather data from weather-stations? Or in the […]

The Bucknell MLA will hold its first meeting on Monday 9/5 at at 5.45pm in the Traditional Reading Room (BERT 213), for members to get to know each other and share their passion for machine learning. Prof. Keegan Kang will give an introductory talk on LSH Schemes. ABSTRACT: There are some challenges with traditional machine learning in a Big Data world. Locality Sensitive Hashing (LSH) schemes are able to mitigate some of these challenges. The idea of LSH schemes will be briefly introduced in this talk by looking at an example of them: sign random projections. This will be followed […]

Mathematics Department Student Colloquium Series Thursday September 1 at noon in Olin 268. Pizza will be served before the talk! You’re Gonna Need A Bigger Boat (or: How math & computation are changing professional game playing)presented by Peter Brooksbank, Professor of Mathematics, Bucknell University ABSTRACT: Those of a mathematical bent have always been drawn to games in which their natural predilections give them an edge over their opponents. Pioneers of computation, such as Alan Turing and John von Neumann, pondered whether machines could compete with, or even outperform humans in games such as Chess, Go, and Poker… even before the first computer was built!

The Mathematics Department’s Distinguished Visiting Professor Dan Timotin, Institute of Mathematics of the Romanian Academy Tuesday, April 26th 4:00 P.M.ROOM 372 in the Olin Science Building Abstract: If A and B are self-adjoint matrices, what is the relation between the eigenvalues of A, those of B, and those of A+B? The talk will describe the unexpected ramifications in various areas of mathematics of this old problem. Some recent developments, mostly pertaining to operator theory, will also be presented.

HONORS THESIS DEFENSE Contraction-based approach to tensor isomorphism Presented by: Anh Kieu ‘22 Thesis Advisor: Pete Brooksbank 2nd Reader: Ben Vollmayr-LeeWednesday, April 20, at 4:00 PMOLIN 372 Everyone is welcome to attend. Abstract: Tensors are natural generalizations of linear transformations to arbitrary “frames” of vector spaces. Just as how a linear transformation can be represented by a matrix, choosing a reference frame allows a tensor to be represented by a multiway array. A fundamental question is to decide when two multiway arrays represent the same tensor relative to different reference frames. This question is commonly known as the tensor isomorphism problem. In this Honors Thesis, we developed a […]

Mathematics Department, Student Colloquium Series MASKS REQUIRED PIZZA SERVED from 11:30 -11:55 in front of Hislop Family Auditorium TALK STARTS AT 12:00 PM “Lies, Damn Lies, and…Olympic Judging Systems” Presented by John W. EmersonDirector of Graduate Studies Department of Statistics and Data Science – Yale University Thursday, April 21, 2022 12:00 P.M. HOLMES HALL – 116 Hislop Family Auditorium Abstract: This talk considers aspects of Olympic judging systems in two different sports, diving and figure skating. The former sport can boast of complete transparency, with the identities of the judges tied to scores available to the general public. The latter sport, in contrast, has […]

Mathematics Department Student Colloquium Series PIZZA SERVED from 11:30 -11:55 in front of Hislop Family Auditorium TALK STARTS AT 12:00 PM “Do I have an artifact in my data? The challenges of acquiring high fidelity data at high rates of acquisition” Presented by Professor Wendelin Wright – Bucknell UniversityHeinemann Family Professor in Engineering, and Professor of Mechanical and Chemical Engineering Thursday, March 24, 2022 12:00 P.M. HOLMES HALL – 116 Hislop Family Auditorium Abstract: I have spent much of my career measuring small, fast features in mechanical test data for a class of materials known as metallic glasses. These are non-crystalline metals that […]

Mathematics Department Student Colloquium Series PIZZA SERVED from 11:30 -11:55 in front of Hislop Family Auditorium TALK STARTS AT 12:00 PM “Number Talks, Math Tasks, and More: Teaching School Mathematics” Presented by COURTNEY RICE ‘08 Department of Mathematics – Bucknell University Thursday, March 3, 2022 12:00 P.M. HOLMES HALL – 116 Hislop Family Auditorium Abstract: In this session, we’ll dive into some of the nuances of teaching school mathematics. How do you develop number sense in students? What about students with different learning styles? How much thought do teachers actually give to the math tasks they use in class? Given by a mathematics and teacher […]

Mathematics Department Student Colloquium Series PIZZA SERVED from 11:30 -11:55 in front of Hislop Family Auditorium TALK STARTS AT 12:00 PM “1, 2, skip a few” Presented by BRETT COLLINS Department of Mathematics – Bucknell University Thursday, February 17, 2022 12:00 P.M. HOLMES HALL – 116 Hislop Family Auditorium Abstract: One of the most basic problems in mathematics is simply counting how many there are of something, such as the number of Sudoku puzzles or the number of arrangements of a Rubik’s Cube, yet this is often notoriously difficult. In this talk, I’ll show through examples how symmetry can be used in many problems […]
