Gravitation

open access: yesTidskrift för Litteraturvetenskap, 2021
Gravitation: Modes of Reading in the Anthropocene In this article, I suggest ‘gravitation’ as a new way of reading in and for the anthropocene, which is characterised by environmentally destructive ‘social acceleration’.

Are Newtonian Gravitation and Geometrized Newtonian Gravitation Theoretically Equivalent? [PDF]

open access: yes, 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.

Interaction Between Macroscopic Quantum Systems and Gravity

open access: yesFrontiers in Physics, 2022
We review experiments and theoretical models about the possible mutual interplay between the gravitational field and materials in the superconducting state or other macroscopic quantum states.

The total mass of the early-type galaxy NGC 4649 (M60) [PDF]

open access: yesSerbian Astronomical Journal, 2008
In this paper the problem of the total mass and the total mass-to-light ratio of the early-type galaxy NGC 4649 (M60) is analyzed. Use is made of two independent techniques: the X-ray methodology which is based on the temperature of the X-ray halo of NGC

Parcours, pratique théorique et documents scientifiques « privés » du physicien Jacques Solomon

open access: yesComptes 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

ELGAR—a European Laboratory for Gravitation and Atom-interferometric Research [PDF]

open access: yesClassical and quantum gravity, 2019
Gravitational waves (GWs) were observed for the first time in 2015, one century after Einstein predicted their existence. There is now growing interest to extend the detection bandwidth to low frequency.

The Gravitation of the Moon Plays Pivotal Roles in the Occurrence of the Acute Myocardial Infarction

open access: yesEnvironmental Health Insights, 2008
Acute myocardial infarction (AMI) is a social burden. However, being able to predict AMI could lead to prevention. A previous study showed only the relation between the lunar phase and the occurrence of AMI, but the period it takes for the moon to orbit ...

Irreversibility of time in general relativity [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Физика, 2022
Background and Objectives: The equations of classical dynamics of particles and waves admit solutions with the reverse flow of time. Therefore, it is generally assumed that classical dynamics does not reflect the irreversibility of time.

Weak Deflection Angle and Shadow by Tidal Charged Black Hole

open access: yesUniverse, 2021
In this article, we calculate the deflection angle of a tidal charged black hole (TCBH) in weak field limits. First, we obtain the Gaussian optical curvature and then apply the Gauss–Bonnet theorem on it.
