## Pi Mu Epsilon

The WV Alpha Chapter of Pi Mu Epsilon, the national mathematics honor society, will host an induction ceremony in honor of our newest members: Jessica Hammersla and Jackson Porter.

**Time:** 5:30PM-7:00PM**Place:** 315 Armstrong

The ceremony features free pizza and a talk by Prof. Nicole Infante**Title:**Math Morsels from the Big and Small Screen

**Abstract:** Movies and television are a big part of peoples’ lives. We may watch to get away from studying, but just as mathematics is a part of life, sometimes it's a part of a movie. How do you react when you find a bit of mathematics suddenly appear on the screen? Perhaps the mathematics is integral to the plot, maybe a side-note, or it’s only in the background. When I unexpectedly find mathematics on the screen, I find great joy (this is math I know!) or curiosity (this is math I don’t know, I want to learn more! Leads to more joy!). I will share some gems that have crossed my path on my journey as a mathematician that spark joy for me.

## BlackHoles@Home

Researchers hoping to better interpret data from the detection of gravitational waves generated by the collision of binary black holes are turning to the public for help. West Virginia University assistant professor Zachariah Etienne is leading what will soon become a global volunteer computing effort.

## Cody Hood Prospectus

Applied Calculus Student Understanding of the Definite Integral

**Date:** 4/9/2019**Time:** 8:30AM-10:00AM**Place:** 403 Armstrong Hall

**Abstract:**Current literature on student understanding of the definite integral strongly suggests that students who perceive the definite integral in a manner that closely aligns with a Riemann sum definition prove to perform better when interacting with applications involving the definite integral in comparison to students with less robust concept images. I look to see if this relationship holds for students in an Applied Calculus course. In my talk I will discuss what current literature says about this topic and what research I plan on conducting that will discover how well students who don’t initially approach the definite integral from a Riemann sum perspective are able to adapt when required to think about the definite integral as an extension of a Riemann sum. A decomposition of the symbolic nature of the definite integral in the context of applications will be used to help students elicit and achieve this level of understanding.

All are welcome to attend.

## Alum Update!

Calistus Ngonghala, a 2011 Ph.D. graduate from the Department of Mathematics, will be a featured presenter for one in a series of webinars on mathematical frontiers sponsored by the National Academies of Science/Engineering/Medicine.

He will be speaking on mathematical approaches to biology, particularly ecology and infectious disease.

Further information is available at http://sites.nationalacademies.org/deps/bmsa/deps_183972

After receiving his Ph.D. in May 2011, Dr. Ngonghala served in postdoctoral positions at the National Institute for Mathematical and Biological Synthesis,

and at the Harvard Medical School, following which he obtained his current position as Assistant Professor of Mathematical Biology in the Mathematics Department at the University of Florida.

Dr. Ngonghala was a student of Mary Ann Clarke of the Mathematics Department and Kenneth Showalter of the Chemistry Department, who were his co-advisors.
