Title: A Brief History of Superconductivity


Superconductors are materials that have zero resistance to the flow of electricity and they also show expulsion of applied magnetic fields. This phenomenon occurs when the materials are cooled below their characteristic critical temperature. Conventional superconductors are understood within the theory of Bardeen, Cooper and Schrieffer (BCS) and researchers are still discovering new families of unconventional superconductors, which are not well understood. During this talk, I will present a historical overview of the field of superconductivity over the past 100 years and I will outline much of what is now known about this fascinating state of matter.

Speaker: Mark Tyler Smith
Title: Internal Kinematics of HII Regions traced by Hydrogen and Helium Radio Recombination Lines


Astrophysics is a topic that covers a broad range of study, from evolution of star forming regions to ground based telescopes. The presentation will focus on mechanisms for star forming regions, Distrubution of Helium in HII regions, the Arecibo Observatory, and research to understand velocity gradients between Hydrogen and Helium in star forming regions.
