Wave-particle duality is the concept in quantum mechanics that quantum entities exhibit particle or wave properties according to the experimental circumstances. [1]: 59 It expresses the inability of the classical concepts such as particle or wave to fully describe the behavior of quantum objects. [2]: III:1-1 During the 19th and early 20th ...
[3] [4] [5] Thomas Young's experiment with light was part of classical physics long before the development of quantum mechanics and the concept of wave–particle duality. He believed it demonstrated that the Christiaan Huygens' wave theory of light was correct, and his experiment is sometimes referred to as Young's experiment [6] or Young's ...
Einstein proposed the wave–particle duality of light. In 1909, using a rigorous fluctuation argument based on a thought experiment and drawing on his previous work on Brownian motion, he predicted the emergence of a "fusion theory" that would combine the two views.
Louis Victor Pierre Raymond, 7th Duc de Broglie (/ də ˈbroʊɡli /, [1] also US: / də broʊˈɡliː, də ˈbrɔɪ /; [2][3] French: [də bʁɔj] [4][5] or [də bʁœj] ⓘ; 15 August 1892 – 19 March 1987) [6] was a French aristocrat and physicist who made groundbreaking contributions to quantum theory. In his 1924 PhD thesis, he postulated ...
A photon (from Ancient Greek φῶς, φωτός (phôs, phōtós) 'light') is an elementary particle that is a quantum of the electromagnetic field, including electromagnetic radiation such as light and radio waves, and the force carrier for the electromagnetic force. Photons are massless particles that always move at the speed of light ...
The Davisson–Germer experiment confirmed the de Broglie hypothesis that matter has wave-like behavior. This, in combination with the Compton effect discovered by Arthur Compton (who won the Nobel Prize for Physics in 1927), [9] established the wave–particle duality hypothesis which was a fundamental step in quantum theory.
The duality represents a major advance in understanding of string theory and quantum gravity. [12] This is because it provides a non-perturbative formulation of string theory with certain boundary conditions and because it is the most successful realization of the holographic principle.
The Dark Ages vs. the Age of Enlightenment. " Black and white thinking " is the false dichotomy of assuming anything not good is evil and vice versa. Black–white binary has often been conflated with the binary of good and evil. Freemasonry has a black-and-white checkerboard as a central symbol within the lodge and all rituals occur on or ...
