PhD Thesis
- J. Fay: On the relativity of motion (2026)
- Note: several chapters need improvements before being publication-ready as their own papers; the thesis was completed in a hurry.
Space
Space conceived as passive must be Euclidean
Inertia
Distinguishing Mach's principle from his hypotheses; the neglected role of environmental circumstances in causation
- J. Fay: Mach’s principle and Mach’s hypotheses (2024) [published by Studies in the History and Philosophy of Science]
- The case for causal monism (critique of Euler, forthcoming)
Gravity
Can gravity be explained as a necessary side-effect of relative-inertia?
- J. Fay and D. Braun: On Reissner’s hypothesis: A review of 20th Century relational models for the unification of gravity and inertia (Forthcoming) [preprint]
- Translation of: H. Reissner: On the possibility of deriving gravity as the direct consequence of the relativity of inertia (1915) [imperfect translation]
