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 proposal to describe gravity by means of a pseudo-Riemannian metric was first made by Einstein and Marcel Grossmann in the so-called Entwurf theory published 1913. [4] Grossmann identified the contracted Riemann tensor as the key for the solution of the problem posed by Einstein.
Lederman explains in the book why he gave the Higgs boson the nickname "The God Particle": This boson is so central to the state of physics today, so crucial to our final understanding of the structure of matter, yet so elusive, that I have given it a nickname: the God Particle.
1911 – Max von Laue publishes the first textbook on special relativity. [51] 1911 – Albert Einstein explains the need to replace both special relativity and Newton's theory of gravity; he realizes that the principle of equivalence only holds locally, not globally. [52] 1912 – Friedrich Kottler applies the notion of tensors to curved ...
General relativity is a theory of gravitation that was developed by Albert Einstein between 1907 and 1915, with contributions by many others after 1915. According to general relativity, the observed gravitational attraction between masses results from the warping of space and time by those masses.
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.
