Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
The solutions require extreme physical conditions unlikely ever to occur in practice, and it remains an open question whether further laws of physics will eliminate them completely. Since then, other—similarly impractical—GR solutions containing CTCs have been found, such as the Tipler cylinder and traversable wormholes .
Gottfried Wilhelm Leibniz (or Leibnitz; [a] 1 July 1646 [O.S. 21 June] – 14 November 1716) was a German polymath active as a mathematician, philosopher, scientist and diplomat who is credited, alongside Sir Isaac Newton, with the creation of calculus in addition to many other branches of mathematics, such as binary arithmetic and statistics.
The term Bharat (Bhārat; pronounced [ˈbʱaːɾət] ⓘ), mentioned in both Indian epic poetry and the Constitution of India, [74] [75] is used in its variations by many Indian languages. A modern rendering of the historical name Bharatavarsha , which applied originally to North India , [ 76 ] [ 77 ] Bharat gained increased currency from the ...
The National Eligibility cum Entrance Test (Undergraduate) or NEET (UG), formerly the All India Pre-Medical Test (AIPMT), is an Indian nationwide entrance examination conducted by the National Testing Agency (NTA) for admission in undergraduate medical programs. [2]
The history of mathematics deals with the origin of discoveries in mathematics and the mathematical methods and notation of the past.Before the modern age and the worldwide spread of knowledge, written examples of new mathematical developments have come to light only in a few locales.
Algebra is the branch of mathematics that studies certain abstract systems, known as algebraic structures, and the manipulation of expressions within those systems. It is a generalization of arithmetic that introduces variables and algebraic operations other than the standard arithmetic operations, such as addition and multiplication.
