Brahmagupta (c. 598 – c. 668 AD) was the first Indian scholar to describe gravity as an attractive force: [38] [39] [failed verification] [40] [41] [failed verification] The earth on all its sides is the same; all people on the earth stand upright, and all heavy things fall down to the earth by a law of nature, for it is the nature of the ...
Brahmagupta (c. 598 – c. 668 CE) was an Indian mathematician and astronomer.He is the author of two early works on mathematics and astronomy: the Brāhmasphuṭasiddhānta (BSS, "correctly established doctrine of Brahma", dated 628), a theoretical treatise, and the Khandakhadyaka ("edible bite", dated 665), a more practical text.
The book begins its first chapter by discussing ancient history and old beliefs regarding gravity and what lies above. This includes a discussion of belief in gods and how those religious views were shaped by the existence of gravity and its prevalence on living beings and all matter. [1]
The formulation of Newtonian gravity in terms of a gravitational constant did not become standard until long after Cavendish's time. Indeed, one of the first references to G is in 1873, 75 years after Cavendish's work. [20] Cavendish expressed his result in terms of the density of the Earth.
At a fixed point on the surface, the magnitude of Earth's gravity results from combined effect of gravitation and the centrifugal force from Earth's rotation. [ 2 ] [ 3 ] At different points on Earth's surface, the free fall acceleration ranges from 9.764 to 9.834 m/s 2 (32.03 to 32.26 ft/s 2 ), [ 4 ] depending on altitude , latitude , and ...
Large-scale gravity anomalies can be detected from space, as a by-product of satellite gravity missions, e.g., GOCE. These satellite missions aim at the recovery of a detailed gravity field model of the Earth, typically presented in the form of a spherical-harmonic expansion of the Earth's gravitational potential, but alternative presentations ...
The book's opening chapters trace the history and evolution of quantum gravity. Starting with pre-socratic philosopher Democritus through to the ideas of Sir Isaac Newton and, eventually, Albert Einstein, Rovelli puts forward a theory that quantum gravity brings great unity to the universe. Rovelli then states that space and time, waves and ...
The first version was Disney movie The Absent-Minded Professor (1961), followed by the sequel Son of Flubber (1963). The 1997 film Flubber starring Robin Williams was a remake of the first film. Two television films were also adapted from the story: The Absent-Minded Professor (1988) TV episode starring Harry Anderson , and The Absent-Minded ...
