Investigations of Materials to Address Alternative Energy Challenges
Thermodynamic properties of materials play a key role in understanding the conduction of heat and electrons. Experimental probes of entropy and heat capacity help elucidate these properties and can be used to inform the development of new materials. In this talk, I will describe an investigation of the contributions to entropy in a metallic glass. Metallic glasses are solids, like crystals, but isotropic and without long-range order, like liquids. At the glass transition temperature, hundreds of degrees below where the solid melts, the hard glass becomes viscous. I will describe an investigation into the entropy and heat capacity at the glass transition, and put these new experimental results into the context of decades-old theories. At the conclusion of the talk, I will connect this work to my current research focus on applying these same experimental tools to solving energy storage problems.

President and Owner of Global Marketing Insights Inc.
Dr. Charles Samuels
Project Manager and Principle Systems Integration Engineer, Vencore, Inc.
Former Bryn Mawr College Visiting Professor
This talk will discuss remote sensing to include its definition, history and several applications. For the purposes of this talk, remote sensing consists of the sensors (e.g., optical elements / instruments), processes, and techniques to collect data remotely (from space satellites, piloted and autonomous aircraft) about the earth (land, water and atmosphere, and human-made features and constructs), and process that data for various applications. These applications are numerous and include environmental science, geospatial science, energy, agriculture and food assessments and security, land and water assessment and use, forestry, oceanography and marine science, weather, meteorology and climate prediction and assessment, and disaster assessment and response. In particular, this talk will focus on the history of remote sensing, and feature the use of LiDAR and Hyperspectral sensors and applications. Dr. Johnson, a world renowned expert, will also provide her insights into owning and operating a small business as well as hold an open discussion of what it's like and how to succeed in operating a woman-owned small business in a male-dominated field.

Simulating the Universe
In the past few decades, simulations of the large scale structure of the universe have played a key role in cosmology, addressing questions from galaxy formation to the nature of dark matter and dark energy. Simulations are required to calculate theoretical predictions of cosmological models in the nonlinear regime of gravitational collapse, and they have become an invaluable tool for developing and calibrating analysis methods for galaxy surveys. After giving an overview of how to simulate the universe, I will discuss how we can use simulations to study the formation of the cosmic web and develop tests of gravity.
