Representations Of Time In Time-Based Media: An Exploration Of The Human Experience Of Temporality In Film And Tv, Nelea Fong
Honors Thesis
Time is an aspect of the human experience that fascinates us but eludes our understanding. Humans have turned to science, philosophy, and theology in our endeavor to understand time, but our shared love and history of storytelling drives us to explore temporality through visual medias that have a structural foundation in time. Expanding our understanding of the human experience of time through time-based media such as movies and TV can point us toward comprehending various forms of time and how each person can perceive said time differently. Using film and TV theory, informed by scientific and philosophical explorations in the …
Characterization Of Extended Uncertainty Principle Black Holes, Juan Uribe, Jonas Mureika
Characterization Of Extended Uncertainty Principle Black Holes, Juan Uribe, Jonas Mureika
Honors Thesis
Black Holes are special objects as they are at the intersection of Quantum Mechanics and General Relativity. A central tenant of quantum mechanics is the Uncertainty Principle that dictates we cannot know with complete certainty position and momentum at the same time. The Extended Uncertainty Principle introduces a position-related uncertainty correction L_* to account for General Relativity. In a previous paper, a black hole metric associated with the Extended Uncertainty Principle was derived, by modifying the metric function of a Schwarzschild black hole. This metric introduces near-horizon structures that should produce observable effects, such as love numbers, gravitational wave echoes, …
Exploring The Dynamics Of Biological Macromolecules At Angstrom Scale, Calvin Foss
Exploring The Dynamics Of Biological Macromolecules At Angstrom Scale, Calvin Foss
Honors Thesis
This thesis studied the Guanylate Kinase (GK) enzyme, which catalyzes the reaction of ATP into ADP, using nano-rheological techniques. A unique experimental setup was created in order to observe the conformational dynamics of the biological macromolecules. An oscillatory force was applied by attaching enzymes to a gold-coated surface and gold nanoparticles. An additional gold-coated surface was placed on top of the setup in order to create a parallel plate capacitor configuration. An oscillatory voltage was then applied across the capacitor to drive the gold nanoparticles and exert a force on the enzymes. The setup detected the ensemble averaged movement of …

Achieving A Stable Magneto-Optical Trap, Chasen S. Himeda
Honors Thesis
The utilization of the Magneto-Optical Trap (MOT) as a method for cooling and confining atoms is a recent development in the field of modern optical physics. Producing an effective MOT relies on a constant magnetic field throughout the trapping region and successful laser cooling, a technique used to achieve optical molasses by slowing particles using a three-dimensional intersection of laser beams. A successful MOT occurs when the trapped atoms slow down to approximately 30 cm/s at a temperature in the microkelvin range and is observable when a small bright orb of atoms is located in the center of the chamber. …
