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 ...

Indian mathematician and astronomer (598–668) Brahmagupta Born c. 598 CE Bhillamala, Gurjaradesa, Chavda kingdom (modern day Bhinmal, Rajasthan, India) Died c. 668 CE (aged c. 69–70) Ujjain, Chalukya Empire (modern day Madhya Pradesh, India) Known for Rules for computing with Zero ...
Clara Moskowitz for Scientific American writes that this "beautiful and philosophical investigation of nature’s weakest force" will help provide insights to readers, despite not being able to answer the fundamental question regarding gravity. [9] Library Journal reviewer Sara R. Tompson calls it "one of the best of the postgravitational-waves ...
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.
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.
1911 – Max von Laue publishes the first textbook on special relativity. [52] 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. [53] 1912 – Friedrich Kottler applies the notion of tensors to curved ...
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.
The first attempts to present a relativistic (classical) field theory of gravitation were also scalar theories. Gunnar Nordström created two such theories. [1]Nordström's first idea (1912) was to simply replace the divergence operator in the field equation of Newtonian gravity with the d'Alembertian operator =.
