An Introduction to Graph Analysis of Chemistry Simulation Data
Abstract: This tutorial covers the conversion of chemical data in Molecular Dynamics simulations into graphs for use in data analysis. For this tutorial, hydrogen bonding is examined through edge distribution analysis of a graph representation of a liquid water system. The test system was drawn from a LAMMPS MD simulation of equilibrated liquid water consisting of 128 water molecules contained
within a periodic box of approximately 16 3. A small portion of this data, 11 timesteps, was pulled for the analysis. Using this data, we instruct on how to perform the following tasks.

An Introduction to Catastrophe Theory
Abstract: In this video, I give an introduction to some basic concepts from catastrophe theory. The goal of the video is to expose the viewer to the important ideas of catastrophe theory by using illustrative examples and visual simulations while avoiding most of the mathematical formalities and jargon. A portion of the video is devoted to introducing how one might use mathematics to model such phenomena with functions, and there are supplemental visualizations.
