Decoherence and Determinism in a One-Dimensional Cloud-Chamber Model  Latest Results for Foundations of Physics on 2018-4-01 12:00am GMT Abstract The hypothesis (Sparenberg et al. in EPJ Web Conf 58:01016, [1]. http://dx.doi.org/10.1051/epjconf/20135801016) that the particular linear tracks appearing in the measurement of a spherically-emitting radioactive source in a cloud chamber are determined by the (random) positions of atoms or molecules inside the… Read more →

Beyond the Dynamical Universe: Unifying Block Universe Physics and Time as Experienced

Theoretical physics and foundations of physics have not made much progress in the last few decades. Whether we are talking about unifying general relativity and quantum field theory (quantum gravity), explaining so-called dark energy and dark matter (cosmology), or the interpretation and implications of quantum mechanics and relativity, there is no consensus in sight. In addition, both enterprises are deeply… Read more →

Weekly Papers on Quantum Foundations (40)

MOND vs. dark matter in light of historical parallels. (arXiv:1910.04368v1 [astro-ph.GA]) 2019年10月11日 星期五 下午8:32 | physics.hist-ph updates on arXiv.org Authors: Mordehai Milgrom MOND is a paradigm that contends to account for the mass discrepancies in the Universe without invoking `dark’ components, such as `dark matter’ and `dark energy’. It does so by supplanting Newtonian dynamics and General Relativity, departing from them… Read more →

50 years in the Landau Institute environment. (arXiv:1810.04447v5 [physics.hist-ph] UPDATED)  physics.hist-ph updates on arXiv.org on 2018-10-20 1:07am GMT Authors: G.E. Volovik Khalatnikov created the unique Institute, where practically all the important areas of theoretical physics have been represented, opening the broad way for collaboration. Here I discuss the influence of the multilayer environment of Landau Institute on my work during 50… Read more →

International Workshop on “The Meaning of the Wave Function”

We are delighted to announce that the International Workshop on “The Meaning of the Wave Function” will be held at Shanxi University, Taiyuan (also known as the Dragon City), China, from October 12, 2018 to October 14, 2018. The workshop is organized by the Research Center for Philosophy of Science and Technology of Shanxi University. The meaning of the wave function… Read more →

The Meaning of the Wave Function: In Search of the Ontology of Quantum Mechanics

Reviewed by Peter J. Lewis, Dartmouth College Shan Gao (2017), The Meaning of the Wave Function: In Search of the Ontology of Quantum Mechanics. Cambridge: Cambridge University Press. Shan Gao has written an exemplary book on the nature of the wave function—its theoretical role, the ontology it represents, and how understanding this ontology can contribute to solving the measurement problem….

On the Nature of Discrete Space-Time: The distance formula, relativistic time dilation and length contraction in discrete space-time. (arXiv:1803.03126v1 [physics.gen-ph])  gr-qc updates on arXiv.org on 2018-3-10 1:42am GMT Authors: David Crouse, Joseph Skufca In this work, the relativistic phenomena of Lorentz-Fitzgerald contraction and time dilation are derived using a modified distance formula that is appropriate for discrete space. This new distance formula… Read more →
