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 show unusually high strengths and hardnesses but limited ductilities due to the occurrence of a microstructural phenomenon known as shear banding. Since understanding and manipulating shear banding is key to utilizing these materials in applications, I seek to measure shear band propagation using a variety of test techniques at rates up to 100 kHz. In this talk, I will demonstrate some of the pitfalls that can result when acquiring data if the signals are not measured using the proper instrumentation or at sufficiently high rates. I will also discuss some of the strategies we have developed to determine whether the behavior we are capturing is real.

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 educator, expect to participate in discussion! You’ll walk out of here with a deeper appreciation and understanding of what goes into the teaching of school mathematics.

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 like this and how we can easily generalize these ideas to more difficult counting problems. One thing that you can certainly count on is having mathematical fun.  

The Mathematical Contest in Modeling: spend 4 days immersed in solving a real-world mathematical problem

Are you interested in using math, statistics, or computer modeling to address real-world problems? Problems like determining the optimal placement of Tesla charging stations in the US, designing a toll highway to optimize traffic flow, or analyzing data from a company’s online product reviews to best inform their future sales strategies? Then maybe mathematical modeling is for you! 
The 2022 MCM/ICM competition will take place February 17-21. Participation is free and on-campus. If you would like to participate or to learn more about this competition, please email b.collins@bucknell.edu. More details and previous problems can also be found at https://www.comap.com/undergraduate/contests/

12:00 P.M.        HOLMES HALL – 116 Hislop Family Auditorium

Abstract: What is the shape with a given perimeter that encloses the largest area? In this talk, we will learn about the history of this problem (dating back to 814 BC) and daring attempts by many great mathematicians whose incomplete solutions led to the development of diverse areas in modern mathematics. Finally, we will reveal the answer and discuss how to solve the problem.  

Colloquium Talk by David Hunter: 12pm Thursday 1/20, HOLMES 116

“When the Supreme Court declares your homework unconstitutional: Reflections on data science and society”

Presented by David Hunter,  Department of Statistics – Penn State University

Thursday, January 20, 2022

12:00 P.M.        HOLMES HALL – 116 Hislop Family Auditorium

Abstract: The 2003 U.S. Supreme Court case known as Gratz v. Bollinger addresses a formula for college admissions that was created by a statistics graduate student (the presenter) for a specific purpose.  The method used to create this formula is considered simplistic by modern machine learning standards; yet the debate that ensued, which could not have happened if a more modern approach had been used, illustrates that science and society do not always benefit from machine learning models that achieve the best possible predictive performance.  This talk discusses the history of the legal case, the admissions formula and how it was created, and the implications of the debate for how we build predictive models.

Like challenging math problems? Take the Putnam!

The Putnam Competition is a famous mathematics contest for undergraduates studying in the U.S. and Canada which has taken place annually since 1927. Bucknell students have had some terrific performances in recent years. This year, the competition takes place on Saturday, December 4, and everyone who likes challenging math problems is encouraged to participate. No advanced mathematical knowledge is required, just creative problem-solving. Participation is free and on-campus. 

Please contact peter.mcnamara@bucknell.edu  if you are interested in participating or have questions.

“What Did You Do Last Summer?”, Presented by Bucknell Students: 11/4 at 12:10PM, Dana 113

“What Did You Do Last Summer?”, Presented by Bucknell Students

NOVEMBER 4 (Thursday) 12:10 P.M. Gardner Lecture Hall – Dana 113

Moderator: Jack de la Parra

Panelists:

Anh Kieu (pronounced like Ahn), ‘22, Software Engineering Intern, Google DeepMind

Emily Desernia ‘22, JPMorgan Chase Bank

Julia Sanger ’22, Research Experience for Undergraduates (Applied Math), Georgia Institute of Technology.

Yang Hong ’23, Undergraduate Research, Bucknell University

Jamie Falla ‘22, Risk Finance, Lockton Companies

Abstract: There are many exciting summer opportunities for students in the mathematical sciences! These range from internships in financial companies to research experiences at other universities to leadership development programs. In this week’s colloquium, a panel of your peers will tell you their experiences. What did they enjoy about their experiences? 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.
