unusual facts about Gravitation



Absolute time and space


—Ernst Mach; as quoted by Ciufolini and Wheeler: Gravitation and Inertia, p. 387

ADM formalism

A comprehensive review of this formalism was published by the same authors in Gravitation: An introduction to current research Louis Witten (editor), Wiley NY (1962); chapter 7, pp 227–265.

Bonnor

William B. Bonnor (born 1920), mathematician and gravitation physicist

Colors Insulting to Nature

After this, Liza undergoes several phases, the first of which is a gravitation toward the punk rock aesthetic, specifically embracing and cultivating the look of Plasmatics performer, Wendy O. Williams.

Euler's three-body problem

Euler's three-body problem is to describe the motion of a particle under the influence of two centers that attract the particle with central forces that decrease with distance as an inverse-square law, such as Newtonian gravity or Coulomb's law.

Glen Rebka

In 1960 Robert Pound carried out together with his assistant Glen Rebka an experiment, the Pound-Rebka experiment, using the Mössbauer effect to measure the gravitational redshift of the radiation from a gamma source in the gravitation field of planet Earth.

Liouville dynamical system

In classical mechanics, Euler's three-body problem describes the motion of a particle in a plane under the influence of two fixed centers, each of which attract the particle with an inverse-square force such as Newtonian gravity or Coulomb's law.

Mason–Weaver equation

The Mason–Weaver equation (named after Max Mason and Warren Weaver) describes the sedimentation and diffusion of solutes under a uniform force, usually a gravitational field.

Newton's Apple

The show's title is based on the rumor of Isaac Newton sitting under a tree and an apple falling near him—or, more popularly, on his head—prompting him to ponder what makes things fall, leading to the development of his theory of gravitation (an event often loosely described as him "discovering" gravity).

Newton's law of universal gravitation

Newton's law of gravitation resembles Coulomb's law of electrical forces, which is used to calculate the magnitude of electrical force between two charged bodies.

Nordström's theory of gravitation

Nordström's theories arose at a time when several leading physicists, including Nordström in Helsinki, Max Abraham in Milan, Gustav Mie in Greifswald, Germany, and Albert Einstein in Prague, were all trying to create competing relativistic theories of gravitation.

Pantur Silaban

In 1967, he went to United States to study General Relativity theory at Central Studies of Gravitation at Syracuse University under direction of Peter Bergmann and Joshua N. Goldberg whom were among authoritative experts in general relativity after the inventor, Albert Einstein.

Paul Lorenzen

Lorenzen took an early interpretation of Steven Weinberg (Gravitation and Cosmology, 1972) for his doubts about geometrical elements of general relativity, believing that Maxwell's equations are to be modified by general relativity instate.

Preon

In the 1948 reprint/edit of his 1930 novel Skylark Three, E. E. Smith postulated a series of 'subelectrons of the first and second type' with the latter being fundamental particles that were associated with the gravitation force.

Problem book

A.P. Lightman, W.H. Press, R.H. Price, and S.A. Teukolsky (1979) Problem Book in Relativity and Gravitation (ISBN 978-0691081625)

Raman Research Institute

The correct theory of gravitation is now believed to be Einstein's General Theory of Relativity.

Scalar theories of gravitation

Scalar theories of gravitation are field theories of gravitation in which the gravitational field is described using a scalar field, which is required to satisfy some field equation.

Two Towers

The Asinelli Tower was used by the scientists Giovanni Battista Riccioli (in 1640) and Giovanni Battista Guglielmini (in the following century) for experiments to study the motion of heavy bodies and the earth rotation.
