Aligned electric and magnetic Weyl fields [PDF]
, 2003 We analyze the spacetimes admitting a direction for which the relative electric and magnetic Weyl fields are aligned. We give an invariant characterization of these metrics and study the properties of its Debever null vectors.

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

The cause of axial rotation of the scoliotic spine [PDF]
, 1991 To explain the cause of axial rotation in a scoliotic vertebral column, the influence of the gravitation force on a spine with a C-scoliosis has been investigated by means of a mechanical model. In this model the gravitation force takes hold of the three-

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.

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.

Are Newtonian Gravitation and Geometrized Newtonian Gravitation Theoretically Equivalent? [PDF]
, 2014 I argue that a criterion of theoretical equivalence due to Clark Glymour [Nous 11(3), 227-251 (1977)] does not capture an important sense in which two theories may be equivalent.

Gravitation-based personalized recommendation algorithm
工程科学学报, 2015 A recommendation algorithm is proposed by introducing the universal law of gravitation into a recommendation system. This new algorithm is named as the gravitation-based personalized recommendation (GBPR) algorithm.

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.
