Scientists from Biology to Mathematics are looking more and more into phenomena that indicate the climate is changing. In this talk, we will engage in a few questions around climate science. For instance, what do scientists in different field’s study that indicates to them that climate change is happening? For the most part, the focus will be centered around what mathematicians do. Also, how do scientists (in particular mathematicians) eliminate other possibilities? Toward the end of the talk, the focus will shift to the electronic devices scientists are attempting to build in order to help prevent the climate from changing.

Our speaker, Dr. Jeffrey Landgren, is currently a member of the UNG Mathematics faculty. His research interests lie primarily a field called Partial Differential Equations and the application to fluid flow. This means, he often look at types of equations that describe liquids/gases and how they move in and around objects. Many mathematicians look at these as they relate to airflow over an airplane or water flowing through a dam. Most of his time has been spent on two projects involving these types of equations. The first project pertains to the movement of electrons in batteries, capacitors, and solar cells and how sound can enhance these electronic devices. The second project focuses on injecting more precision into the equations that illustrate the flow of sea ice in the Arctic. For his last trick, he once hiked the Appalachian Trail in 2009.
