The Effect of the Gravitation of the Moon on Frequency of Births

Environmental Health Insights, 2010
The purpose of this study was to examine the influence of the gravitation of the Moon on the frequency of births in Kyoto, Japan. A retrospective cohort analysis of 1007 consecutive births without the use of the induction agents was conducted on a ...

Predictions and Outcomes for the Dynamics of Rotating Galaxies

Galaxies, 2020
A review is given of a priori predictions made for the dynamics of rotating galaxies. One theory—MOND—has had many predictions corroborated by subsequent observations.

The Equivalence Principle Revisited [PDF]

, 2002
A precise formulation of the strong Equivalence Principle is essential to the understanding of the relationship between gravitation and quantum mechanics.

Gravitational atoms [PDF]

Physical Review D, 2019
Particles in a yet unexplored dark sector with sufficiently large mass and small gauge coupling may form purely gravitational atoms (quantum gravitational bound states) with a rich phenomenology. In particular, we investigate the possibility of having an observable signal of gravitational waves or ultra high energy cosmic rays from the decay of ...

Quark Soup al dente: Applied Superstring Theory [PDF]

, 2008
We discuss the application of the AdS/CFT correspondence to possibly gain new physical insights for the strongly coupled quark-gluon plasma. This article provides an informal summary of a talk given by RCM at the 18th International Conference on General ...

Statistical Mechanics-Based Schrödinger Treatment of Gravity

Entropy, 2019
The entropic gravity conception proposes that what has been traditionally interpreted as unobserved dark matter might be merely the product of quantum effects.

Gravitational anyons [PDF]

Physical Review Letters, 1990
Summary: We describe some novel effects generated by the gravitational Chern-Simons term similar to those induced by its electromagnetic counterpart. In particular, a structureless particle source generates a gravimagnetic field. Conversely, it causes a spinning source to contribute to the static Newtonian potential, thereby violating the equivalence ...

Adam Smith et la physique de Newton

Œconomia, 2012
In most of Smith's writings we find references to the natural philosophy of Newton. Beyond the use of Newtonian concepts and laws to deal with specific issues, we would like to focus on the relationship between the Smithian representation of the social ...

Superconductor Meissner Effects for Gravito-Electromagnetic Fields in Harmonic Coordinates Due to Non-Relativistic Gravitational Sources

Frontiers in Physics, 2022
There is much discrepancy in the literature concerning the possibility of a superconductor expelling gravito-electromagnetic fields just as it expels electromagnetic fields in the Meissner effect.
