Path integral formulationThe path integral formulation is a description in quantum mechanics that generalizes the action principle of classical mechanics. It replaces the classical notion of a single, unique classical trajectory for a system with a sum, or functional integral, over an infinity of quantum-mechanically possible trajectories to compute a quantum amplitude. This formulation has proven crucial to the subsequent development of theoretical physics, because manifest Lorentz covariance (time and space components of quantities enter equations in the same way) is easier to achieve than in the operator formalism of canonical quantization.
Wiener processIn mathematics, the Wiener process is a real-valued continuous-time stochastic process named in honor of American mathematician Norbert Wiener for his investigations on the mathematical properties of the one-dimensional Brownian motion. It is often also called Brownian motion due to its historical connection with the physical process of the same name originally observed by Scottish botanist Robert Brown.
Sacred traditionSacred tradition, also called Holy tradition or Apostolic tradition, is a theological term used in Christian theology. According to this theological position, sacred tradition is the foundation of the doctrinal and spiritual authority of Christianity and of the Bible. Thus, the Bible must be interpreted within the context of sacred tradition and within the community of the denomination. The denominations that ascribe to this position are the Catholic, Eastern Orthodox, and Oriental Orthodox churches, and the Assyrian churches (the Ancient Church of the East and the Assyrian Church of the East).
TraditionA tradition is a belief or behavior (folk custom) passed down within a group or society with symbolic meaning or special significance with origins in the past. A component of cultural expressions and folklore, common examples include holidays or impractical but socially meaningful clothes (like lawyers' wigs or military officers' spurs), but the idea has also been applied to social norms such as greetings. Traditions can persist and evolve for thousands of years—the word tradition itself derives from the Latin tradere literally meaning to transmit, to hand over, to give for safekeeping.
Experimental literatureExperimental literature is a genre of literature that is generally "difficult to define with any sort of precision." It experiments with the conventions of literature, including boundaries of genres and styles; for example, it can be written in the form of prose narratives or poetry, but the text may be set on the page in differing configurations than that of normal prose paragraphs or in the classical stanza form of verse. It may also incorporate art or photography.
Oral traditionOral tradition, or oral lore, is a form of human communication wherein knowledge, art, ideas and cultural material is received, preserved, and transmitted orally from one generation to another. The transmission is through speech or song and may include folktales, ballads, chants, prose or poetry. In this way, it is possible for a society to transmit oral history, oral literature, oral law and other knowledge across generations without a writing system, or in parallel to a writing system.
Postmodern literaturePostmodern literature is a form of literature that is characterized by the use of metafiction, unreliable narration, self-reflexivity, intertextuality, and which often thematizes both historical and political issues. This style of experimental literature emerged strongly in the United States in the 1960s through the writings of authors such as Kurt Vonnegut, Thomas Pynchon, William Gaddis, Philip K. Dick, Kathy Acker, and John Barth.
