How Are Entanglement Entropies Related To Entropy Bounds?, Emily Adlam
How Are Entanglement Entropies Related To Entropy Bounds?, Emily Adlam
Philosophy Faculty Articles and Research
In this paper we seek to understand what current knowledge of entanglement entropies suggests about the appropriate way to interpret the covariant entropy bound. We first begin by arguing that just as in the classical case, a universal bound on the von Neumann entropy could have either an epistemic or ontological origin. We then consider several possible ways of explaining the bound as a consequence of features of the entanglement entropy. We discuss consider area laws in condensed matter and quantum field theory, arguing that they suggest an epistemic reading of the bound. We also discuss the ‘spacetime from entanglement’ …
A Computational Investigation Of Wood Selection For Acoustic Guitar, Jonah Osterhus
A Computational Investigation Of Wood Selection For Acoustic Guitar, Jonah Osterhus
Senior Honors Theses
The acoustic guitar is a stringed instrument, often made of wood, that transduces vibrational energy of steel strings into coupled vibrations of the wood and acoustic pressure waves in the air. Variations in wood selection and instrument geometry have been shown to affect the timbre of the acoustic guitar. Computational methods were utilized to investigate the impact of material properties on acoustic performance. Sitka spruce was deemed the most suitable wood for guitar soundboards due to its acoustic characteristics, strength, and uniform aesthetic. Mahogany was deemed to be the best wood for the back and sides of the guitar body …

Marie Curie: The Quantum Matriarch, Diptiman Das
Student Publications
Entitled “Marie Curie: The Quantum Matriarch,” this paper illuminates the extraordinary life and enduring legacy of Marie Curie, whose groundbreaking work in radioactivity revolutionized the scientific landscape. Born as Maria Skłodowska in the heart of Warsaw, Curie’s odyssey from Poland’s clandestine Flying University to the hallowed halls of Paris’ Sorbonne epitomizes her tenacious quest for enlightenment amidst the shackles of societal norms. In collaboration with her spouse, Pierre Curie, she discovered the elements polonium and radium, thereby introducing the concept of “radioactivity” to the world and securing Nobel accolades in both Physics and Chemistry. This paper ventures into her intimate …
Quantum Realities: A Comparative Analysis Of Interpretations Addressing The Measurement Problem In Quantum Mechanics, Adib Kabir
Student Publications
This paper examines the measurement problem in quantum mechanics and evaluates three major interpretations: the Copenhagen interpretation, the Many-Worlds Interpretation (MWI), and the Pilot-Wave theory. The Copenhagen interpretation posits that particles exist in superposition until measured, at which point their wave functions collapse. MWI suggests that all possible outcomes occur in separate, non-interacting branches of the universe, eliminating wave function collapse but introducing an infinite number of unobservable universes. The Pilot-Wave theory reintroduces determinism through hidden variables, guiding particles along definite paths. The paper concludes that the Copenhagen interpretation is the most plausible, balancing empirical adequacy, ontological clarity, and simplicity.
The Roaring Lion Of Berlin: The Life, Thought, And Influence Of Eugen Dühring, Arden Roy
The Roaring Lion Of Berlin: The Life, Thought, And Influence Of Eugen Dühring, Arden Roy
Undergraduate Research Symposium
The life and influence of 19th-century German polymath Eugen Dühring remain but a mere footnote in the history of ideas, being primarily relegated to the status of little more than a theoretical rival to Marxism in the German socialist movement and the occasional object of Freidrich Nietzsche's rhetorical flogging. Despite the current consensus on the subject, Eugen Dühring was a scholar of vast, remarkable learnedness, contributing greatly to philosophy, economics, and the natural sciences. The aim of this talk will be to clear the fog surrounding the life and work of the controversial blind scholar and give an account of …

Trumpet Directivity From A Rotating Semicircular Array, Samuel D. Bellows, Joseph E. Avila, Timothy W. Leishman
Trumpet Directivity From A Rotating Semicircular Array, Samuel D. Bellows, Joseph E. Avila, Timothy W. Leishman
Directivity
The directivity function of a played musical instrument describes the angular dependence of its acoustic radiation and diffraction about the instrument, musician, and musician’s chair. Directivity influences sound in rehearsal, performance, and recording environments and signals in audio systems. Because high-resolution, spherically comprehensive measurements of played musical instruments have been unavailable in the past, the authors have undertaken research to produce and share such data for studies of musical instruments, simulations of acoustical environments, optimizations of microphone placements, and other applications. The authors acquired the data from repeated chromatic scales produced by a trumpet played at mezzo-forte in an anechoic …

The Temporal Asymmetry Of Influence Is Not Statistical, Emily Adlam
The Temporal Asymmetry Of Influence Is Not Statistical, Emily Adlam
Mathematics, Physics, and Computer Science Faculty Articles and Research
We argue that the temporal asymmetry of influence is not merely the result of thermodynamics: it is a consequence of the fact that modal structure of the universe must admit only processes which cannot give rise to contradictions. We appeal to the process matrix formalism developed in the field of quantum foundations to characterise processes which are compatible with local free will whilst ruling out contradictions, and argue that this gives rise to ‘consistent chaining’ requirements that explain the temporal asymmetry of influence. We compare this view to the perspectival account of causation advocated by Price and Ramsey.

The Meaning Of Dark, Light And Shadows: Inferences In Art, Materiality And Cultural Practices, Frank Prendergast
The Meaning Of Dark, Light And Shadows: Inferences In Art, Materiality And Cultural Practices, Frank Prendergast
Book/Book Chapter
Our visual awareness relies on light acting on the eye to perceive materiality and colour. Medieval thought wrestled to articulate and comprehend its nature. The notebooks of Leonardo Da Vinci, for example, included his descriptions to define light and make comparisons so as to differentiate between light and shadow. His focus was on the illumination of surfaces from the perspective of a painter, seeing shadows as ‘the diminution of light by the intervention of an opaque body’ and ‘the counterpart of luminous rays’. In his mind, a shadow ‘stood between light and darkness’, with darkness being ‘the absence of light’. …

Deathtrap, Blake Traylor
Vázquez-Valarezo Poetry Award
I could have titled this one "Bad Trip in an Elevator," but that would twist the poem away from its authenticity. You'll have to trust me on this one: this happened. Not in the usual sense, but in that fiction-is-truth-in-a-funhouse-mirror, postmodern Tim O'Brien sense. And hallucinogens were not involved, nor are they encouraged or condoned. (Do with that Wretched Passive Voice what you will.)
If the word "Deathtrap" didn't amuse me so much, I really could have run with the title "Tired." Or maybe "Very Tired" would have been better. And then there are always the big-hitters: "Fatigue," "Exhaustion," "Are …

Patrick Aidan Heelan’S The Observable: Heisenberg’S Philosophy Of Quantum Mechanics, Paul Downes
Research Resources
The publication of Patrick Aidan Heelan’s The Observable, with forewords from Michel Bitbol, editor Babette Babich and the author himself, offers a timely invitation to reconsider the relation between quantum physics and continental philosophy.
Patrick Heelan does so, as a contemporary of and interlocutor with Werner Heisenberg on these issues, as a physicist himself who trained with leading figures of quantum mechanics (QM), Erwin Schrödinger and Eugene Wigner. Moreover, Heelan highlights Heisenberg’s interest in phenomenology as ‘a friend and frequent visitor of Martin Heidegger’ (55). Written originally in 1970 and unpublished then for reasons Babich explicates in her foreword, …

The Perceived Effect Of Transformer Core Metal On Musical Sounds, Addie Lopshire-Bratt
The Perceived Effect Of Transformer Core Metal On Musical Sounds, Addie Lopshire-Bratt
Honors Scholars Collaborative Projects
Transformers are an electronic component used to change the voltage from one part of a circuit to the next. They appear in most audio equipment from the earlier eras but left a sonic signature on the sound waves passed through them. Most research conducted on the “sound” of transformers has focused on their effect on simple sine waves passed through the component, not complex–musical–waves. This thesis seeks to organize the research available about transformers and simple sine waves and compare it with the gamut of opinions that audio professionals hold about their sound.

An Analysis Of The Debate Over Creation, Evolution, And The Timeline Of The Universe At An Ecumenical Christian University, Mason Pohlman
Honors Scholars Collaborative Projects
Throughout a significant portion of history and within modern culture, the fields of science and religion appear to be competing for the same holds in a person’s belief system. Universities are where academics and the sciences are the prevailing held truth, while in churches, the Bible reigns as supreme authority. However, in a Christian academic setting, the predominate school of thought in belief systems might turn into a little more of a melting pot. By analyzing gathered personal data (via surveys and interviews), one can begin to piece together the predominate thoughts on the apparent conflict between religion and science …

Reformulating Bell's Theorem: The Search For A Truly Local Quantum Theory, Mordecai Waegell, Kelvin J. Mcqueen
Reformulating Bell's Theorem: The Search For A Truly Local Quantum Theory, Mordecai Waegell, Kelvin J. Mcqueen
Philosophy Faculty Articles and Research
The apparent nonlocality of quantum theory has been a persistent concern. Einstein et al. (1935) and Bell (1964) emphasized the apparent nonlocality arising from entanglement correlations. While some interpretations embrace this nonlocality, modern variations of the Everett-inspired many worlds interpretation try to circumvent it. In this paper, we review Bell's “no-go” theorem and explain how it rests on three axioms, local causality, no superdeterminism, and one world. Although Bell is often taken to have shown that local causality is ruled out by the experimentally confirmed entanglement correlations, we make clear that it is the conjunction of the …
Performing Near Field Acoustic Holography Scans For The Purpose Of Finding The Acoustic Impedance Of A Violin, Zamara Tomko
Performing Near Field Acoustic Holography Scans For The Purpose Of Finding The Acoustic Impedance Of A Violin, Zamara Tomko
Student Research, Papers, and Creative Works
This project aimed to measure the acoustic impedance of the violin so that the violin can be better understood from an acoustic standpoint. Near field acoustic holography scans are to be conducted at the open A string resonance of the violin (440 Hz). Pressure microphones along the back plate of the violin allow pressure and particle velocity to be measured, and with that, the acoustic impedance to be calculated and mapped in 1 cm x 1cm increments. This work presents a guide for this procedure. The set-up method and materials used are detailed and the analysis and computations of values …

Sympathetic Physics: The Keely Motor And The Laws Of Thermodynamics In Nineteenth-Century Culture, Robert Macdougall
Sympathetic Physics: The Keely Motor And The Laws Of Thermodynamics In Nineteenth-Century Culture, Robert Macdougall
History Publications
In Philadelphia in the 1870s, John Worrell Keely announced the invention of a fantastic new motor that could, he promised, drive locomotives, power factories, and even defy gravity without fuel or heat. The Keely Motor became the most notorious perpetual motion scheme of the nineteenth century, attracting believers and investors for nearly thirty years. This article explores the “work” the motor performed for Keely, his supporters, and his critics—not physical work, but financial, cultural, and psychological. To investors, the Keely Motor represented a dream of riches without effort. To Keely’s critics, the motor offered an opportunity to defend the legitimacy …
