Science Speakers series
Emma Burton will talk about her research project, building an ultraviolet laser for a thorium nuclear referenced atomic clock. And about her experience in graduate school.
Emma graduated from Goshen College in 2022 and is working on her PhD at the University of Colorado, Boulder. She's part of the STROBE collaboration focussed on designing and building new kinds of microscopes.
Students in the Electronics class taught by Prof. Paul Meyer Reimer spend the last month of class on a project. Each project uses the popular Arduino microprocesser programmed in C, controlling sensors, lights, sounds, motors nd more.
This year's projects:

A granular system behaves in some ways like a liquid with an ability to flow and in some ways like a solid with a stable fixed structure if undisturbed. A tiny stimulus to the pile most often results in only a small response, but the same small stimulus can also create an unpredictable and catastrophic collapse of the pile.
Collapses occur both in natural settings, with hazards such as landslides and snow avalanches, and in industrial situations, where granular materials like sand or agricultural grains need to flow freely.
We use a simple experimental system – a 3D conical pile of uniform
beads – in order to model these real-world physical systems. We
investigate the dynamic response of the pile by recording avalanches
from the pile over the course of tens of thousands of bead drops.
