Há 13 horas · Quantum mechanics. Matter waves are a central part of the theory of quantum mechanics, being half of wave–particle duality. At all scales where measurements have been practical, matter exhibits wave -like behavior. For example, a beam of electrons can be diffracted just like a beam of light or a water wave.
Há 13 horas · The chronology of the universe describes the history and future of the universe according to Big Bang cosmology. Research published in 2015 estimates the earliest stages of the universe's existence as taking place 13.8 billion years ago, with an uncertainty of around 21 million years at the 68% confidence level.
Há 13 horas · Measures are foundational in probability theory, integration theory, and can be generalized to assume negative values, as with electrical charge. Far-reaching generalizations (such as spectral measures and projection-valued measures) of measure are widely used in quantum physics and physics in general.
Há 13 horas · In mathematical physics, special unitary group SO(3) has an eight-dimensional adjoint representation whose colors are ascribed gauge symmetries that represent the vectors of the eight gluons in the Standard Model. The number 8 is involved with a number of interesting mathematical phenomena related to the notion of Bott periodicity.

Open access ( OA) is a set of principles and a range of practices through which research outputs are distributed online, free of access charges or other barriers. [1]
Há 13 horas · u-tokyo.ac.jp. The University of Tokyo ( 東京大学, Tōkyō daigaku, abbreviated as Tōdai (東大) in Japanese and UTokyo in English [7]) is a public research university in Bunkyō, Tokyo, Japan. Founded in 1877 as the nation's first modern university by the merger of several pre-westernisation era institutions, its direct predecessors ...
Há 13 horas · In mathematics. Six is the smallest positive integer which is neither a square number nor a prime number. It is the second smallest composite number after four, equal to the sum and the product of its three proper divisors ( 1, 2 and 3 ). [1] As such, 6 is the only number that is both the sum and product of three consecutive positive numbers.
