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 ]
An illustration of God as the architect of the universe can be found in a Bible from the Middle Ages [6] and the comparison of God to an architect has been used by Christian apologists and teachers. Thomas Aquinas said in the Summa : "God, Who is the first principle of all things, may be compared to things created 'as the architect is to things ...
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.
Philosophiæ Naturalis Principia Mathematica (English: The Mathematical Principles of Natural Philosophy), [1] often referred to as simply the Principia (/ p r ɪ n ˈ s ɪ p i ə, p r ɪ n ˈ k ɪ p i ə /), is a book by Isaac Newton that expounds Newton's laws of motion and his law of universal gravitation.
The central claim of the book is that the theory of quantum mechanics and the theory of relativity together help us understand how universes could have formed out of nothing. [9] The authors write: Because there is a law such as gravity, the universe can and will create itself from nothing.
The book that educated at least two generations of researchers in gravitational physics. Comprehensive and encyclopedic, the book is written in an often-idiosyncratic way that you will either like or not. Pankaj Sharan writes: [7] This large sized (20cm × 25cm), 1272 page book begins at the very beginning and has everything on gravity (up to ...
