Testing Universal Gravitation in the Laboratory, or the Significance of Research on the mean Density of the Earth and Big G, 1798-1898: Changing Pursuits and long-term methodological-experimental Continuity [PDF]
, 2010 This paper seeks to provide a historically well-informed analysis of an important post-Newtonian area of research in experimental physics between 1798 and 1898, namely the determination of the mean density of the earth and, by the end of the nineteenth ...

Symposium - International Astronomical Union, 1993 In approximately half the systems currently recognized as strongly gravitationally lensed, the background object is an extragalactic radio source. Radio observations have played an important role in the identification of lensed systems, and the properties of radio sources allow some of the astrophysical applications of lensing to be realized.

Mechanics and composition of middle cerebral arteries from simulated microgravity rats with and without 1-h/d -Gx gravitation [PDF]
, 2014 Background: To elucidate further from the biomechanical aspect whether microgravity-induced cerebral vascular maladaptation might be a contributing factor to postflight orthostatic intolerance and the underlying mechanism accounting for the potential ...

Parcours, pratique théorique et documents scientifiques « privés » du physicien Jacques Solomon
Comptes Rendus. Physique, 2022 Jacques Solomon (1908-1942) is an important figure in the theoretical physics of the 1930s in France. His published works and the personal documents that have been entrusted to me, reveal specific writing processes and theoretical elaborations, which his

Gravitational thermodynamics [PDF]
Complexity, 1997 The gravitational N-body problem, for $N>2$, is the oldest unsolved problem in mathematical physics. Some of the most ideal examples that can be found in nature are globular star clusters, with $N \sim 10^6$. In this overview, I discuss six types of fundamental sources of unpredictability, each of which poses a different challenge to attempts to ...

On the invisibility and impact of Robert Hooke’s theory of gravitation
Open Philosophy, 2020 Robert Hooke’s theory of gravitation is a promising case study for probing the fruitfulness of Menachem Fisch’s insistence on the centrality of trading zone mediators for rational change in the history of science and mathematics.

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.
