Similarity, Adequacy, And Purpose: Understanding The Success Of Scientific Models, Melissa Jacquart
Similarity, Adequacy, And Purpose: Understanding The Success Of Scientific Models, Melissa Jacquart
Electronic Thesis and Dissertation Repository
A central component to scientific practice is the construction and use of scientific models. Scientists believe that the success of a model justifies making claims that go beyond the model itself. However, philosophical analysis of models suggests that drawing inferences about the world from successful models is more complex. In this dissertation I develop a framework that can help disentangle the related strands of evaluation of model success, model extendibility, and the ability to draw ampliative inferences about the world from models.
I present and critically assess two leading accounts of model assessment, arguing that neither is sufficient to provide …
Probabilistic Reasoning In Cosmology, Yann Benétreau-Dupin
Probabilistic Reasoning In Cosmology, Yann Benétreau-Dupin
Electronic Thesis and Dissertation Repository
Cosmology raises novel philosophical questions regarding the use of probabilities in inference. This work aims at identifying and assessing lines of arguments and problematic principles in probabilistic reasoning in cosmology.
The first, second, and third papers deal with the intersection of two distinct problems: accounting for selection effects, and representing ignorance or indifference in probabilistic inferences. These two problems meet in the cosmology literature when anthropic considerations are used to predict cosmological parameters by conditionalizing the distribution of, e.g., the cosmological constant on the number of observers it allows for. However, uniform probability distributions usually appealed to in such arguments …
On The Physical Explanation For Quantum Computational Speedup, Michael Cuffaro
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 …
The Reasonable Effectiveness Of Mathematics In The Natural Sciences, Nicolas Fillion
The Reasonable Effectiveness Of Mathematics In The Natural Sciences, Nicolas Fillion
Electronic Thesis and Dissertation Repository
One of the most unsettling problems in the history of philosophy examines how mathematics can be used to adequately represent the world. An influential thesis, stated by Eugene Wigner in his paper entitled "The Unreasonable Effectiveness of Mathematics in the Natural Sciences," claims that "the miracle of the appropriateness of the language of mathematics for the formulation of the laws of physics is a wonderful gift which we neither understand nor deserve." Contrary to this view, this thesis delineates and implements a strategy to show that the applicability of mathematics is very reasonable indeed.
I distinguish three forms of the …
