Supernovae Distributions And Their Relationships To Classes Of Stars, Sydney Menne
Supernovae Distributions And Their Relationships To Classes Of Stars, Sydney Menne
Arts & Sciences Undergraduate Showcase
Aims. Data from astronomical catalogs are plotted as spatial distributions of stars and supernovae throughout the Milky Way galaxy and the universe. I examined correlations seen between the luminosity classes of stars, types of supernovae, and selection effects observed in the data.
Methods. Data was gathered from three catalogs; the Gliese Catalog of Nearby Stars, the Tycho-2 Catalog, and the Open Supernova Catalog. Graphs and diagrams were created to visualize the distributions of the stellar luminosity classes and supernova types at different radial distances from the Sun. Trendlines were fit through the data to examine extrapolated predictions.
Results/Conclusions. Documenting stars …

Four Derivations Of Schrödinger’S Time Dependent Equation, Sydney Swanson
Essential Studies UNDergraduate Showcase
Physics and the natural world have been studied by humans since the first person wondered ‘Why?’ The Schrödinger equation is important because it attempts to describe a relatively new (to us) and unfamiliar part of our universe, behavior of subatomic particles, and helps modern scientists uncover secrets that have proven useful in technology and explaining our origins. The time dependent Schrödinger equation can be derived from various starting points in Classical such as the equation of a wave, the time independent Schrödinger equation, and Hamilton-Jacobi equations. Why Quantum mechanics exists, useful applications, and cases when it fails or is inaccurate …
