In the era of the old quantum theory, starting from Max Planck's proposal of quanta in his model of blackbody radiation (1900) and Albert Einstein's adaptation of the concept to explain the photoelectric effect (1905), and until Erwin Schrödinger published his eigenfunction equation in 1926, [1] the concept behind quantum numbers developed based on atomic spectroscopy and theories from ...
Computer engineers typically describe a modern computer's operation in terms of classical electrodynamics.Within these "classical" computers, some components (such as semiconductors and random number generators) may rely on quantum behavior, but these components are not isolated from their environment, so any quantum information quickly decoheres.
The word quantum is the neuter singular of the Latin interrogative adjective quantus, meaning "how much"."Quanta", the neuter plural, short for "quanta of electricity" (electrons), was used in a 1902 article on the photoelectric effect by Philipp Lenard, who credited Hermann von Helmholtz for using the word in the area of electricity.
Loop quantum gravity (LQG) is a theory of quantum gravity that incorporates matter of the Standard Model into the framework established for the intrinsic quantum gravity case.
The theory of computation can be considered the creation of models of all kinds in the field of computer science. Therefore, mathematics and logic are used. In the last century, it separated from mathematics and became an independent academic discipline with its own conferences such as FOCS in 1960 and STOC in 1969, and its own awards such as the IMU Abacus Medal (established in 1981 as the ...

Chronologically, Mongolian borrowing of Chinese vocabulary took place later than that of the Sinoxenic languages. [1] In contrast to Sinoxenic vocabulary, Sino-Mongolian vocabulary is not the result of an attempt to adopt Chinese as the literary language or the adoption of the Chinese writing system as a whole.
Ho Chi Minh Thought (Vietnamese: Tư tưởng Hồ Chí Minh) is a political philosophy that builds upon Marxism–Leninism and the ideology of Vietnamese revolutionary Ho Chi Minh.
