Can Bohmian Mechanics Be Made Relativistic?, Detlef Dürr, Sheldon Goldstein, Travis Norsen, Ward Struyve, Nino Zaghì

Physics: Faculty Publications

In relativistic space-time, Bohmian theories can be formulated by introducing a privileged foliation of space-time. The introduction of such a foliation – as extra absolute space-time structure – would seem to imply a clear violation of Lorentz invariance, and thus a conflict with fundamental relativity. Here, we consider the possibility that, instead of positing it as extra structure, the required foliation could be covariantly determined by the wave function. We argue that this allows for the formulation of Bohmian theories that seem to qualify as fundamentally Lorentz invariant. We conclude with some discussion of whether or not they might also …

The Politics Media Equation:Exposing Two Faces Of Old Nexus Through Study Of General Elections,Wikileaks And Radia Tapes, Ratnesh Dwivedi Mr

Ratnesh Dwivedi

The important identity of a responsible media is playing an unbiased role in reporting a matter without giving unnecessary hype to attract the attention of the gullible public with the object of making money and money only.After reporting properly the media can educate the public to form their own opinion in the matters of public interest. Throughout the centuries, the world has never existed without information and communication, hence the inexhaustible essence of mass media. The government has the power to either make or reject whatever that will exist within its environment. It also determines how free the mass media …

Yet Another Snapshot Of Foundational Attitudes Toward Quantum Mechanics, Travis Norsen, Sarah Nelson

Physics: Faculty Publications

A survey probing respondents' views on various foundational issues in quantum mechanics was recently created by Schlosshauer, Kofler, and Zeilinger [arXiv:1301.1069] and then given to 33 participants at a quantum foundations conference. Here we report the results of giving this same survey to the attendees at another recent quantum foundations conference. While it is rather difficult to conclude anything of scientific significance from the poll, the results do strongly suggest several interesting cultural facts -- for example, that there exist, within the broad field of "quantum foundations", sub-communities with quite different views, and that (relatedly) there is probably …

How To Think About Indiscernible Particles, Daniel Joseph Giglio

Theses and Dissertations

Permutation symmetries which arise in quantum mechanics pose an intriguing problem. It is not clear that particles which exhibit permutation symmetries (i.e. particles which are indiscernible, meaning that they can be swapped with each other without this yielding a new physical state) qualify as "objects" in any reasonable sense of the term. One solution to this puzzle, which I attribute to W.V. Quine, would have us eliminate such particles from our ontology altogether in order to circumvent the metaphysical vexations caused by permutation symmetries. In this essay I argue that Quine's solution is too rash, and in its place I …

The Fine-Tuning Of Nomic Behavior In Multiverse Scenarios, Max Lewis Edward Andrews

Masters Theses

The multiverse hypothesis (the view that there is not just one world or universe in existence, bur rather that there are many) is the leading alternative to the competing fine-tuning hypothesis (the laws of physics and constants are fine-tuned for the existence of life). The multiverse dispels many aspects of the fine-tuning argument by suggesting that there are different initial conditions in each universe, varying constants of physics, and the laws of nature lose their known arbitrary values; thus, making the previous single-universe argument from fine- tuning incredibly weak. The position that will be advocated will be that a form …

Transubstantiation And Quantum Physics: The Parallels Of Mystery In Religion And Science, Zachary Sexton

Spring 2013, Science and Religion

As the study of physics has progressed into the abstract realm of quanta, some have argued that the notion of transubstantiation is an unreasonable understanding of the Eucharist. However, when confronted with the uncertainty that modern physics presents, sharp parallels between this uncertainty and the metaphysical mysteries of transubstantiation. If it is reasonable to accept uncertainty in quantum physics, then it should be reasonable to accept the mysteries within the metaphysical world.

Heisenberg’S Uncertainty Principle, Matthew Santos

Spring 2013, Kuhn's Philosophy of Science

In 1926 Werner Heisenberg’s Uncertainty Principle set the field of quantum mechanics on a trajectory riddled with indeterminacy, a trajectory which stood in stark contrast with the classical Newtonian world causality and origin. In doing so, Heisenberg effectively created a new standard by which physicists conducted their science, broadened the scope of that science, and altered the very worldview of those physicists. Such paradigmatic upheaval fits the philosophical model of scientific progress posited by Thomas Kuhn. However, in the ever-changing and still-evolving world of quantum mechanics, Heisenberg’s revolutionary work uniquely strays from Kuhn’s model in its further implications.

On The Physical Explanation For Quantum Computational Speedup, Michael Cuffaro

Electronic Thesis and Dissertation Repository

The aim of this dissertation is to clarify the debate over the explanation of quantum speedup and to submit, for the reader’s consideration, a tentative resolution to it. In particular, I argue that the physical explanation for quantum speedup is precisely the fact that the phenomenon of quantum entanglement enables a quantum computer to fully exploit the representational capacity of Hilbert space. This is impossible for classical systems, joint states of which must always be representable as product states. I begin the dissertation by considering, in Chapter 2, the most popular of the candidate physical explanations for quantum speedup: the …

Uv-Visible Microscope Spectrophotometric Polarization And Dichroism With Increased Discrimination Power In Forensic Analysis, Dale Kevin Purcell

All Open Access Legacy Dissertations and Capstone Projects

Microanalysis of transfer (Trace) evidence is the application of a microscope and microscopical techniques for the collection, observation, documentation, examination, identification, and discrimination of micrometer sized particles or domains. Microscope spectrophotometry is the union of microscopy and spectroscopy for microanalysis. Analytical microspectroscopy is the science of studying the emission, reflection, transmission, and absorption of electromagnetic radiation to determine the structure or chemical composition of microscopic-size materials. Microscope spectrophotometry instrument designs have evolved from monochromatic illumination which transmitted through the microscope and sample and then is detected by a photometer detector (photomultiplier tube) to systems in which broad-band (white light) illumination …
