Paternoster lift
A paternoster lift, also called a paternoster elevator, is a passenger elevator with a chain of open, doorless cabins moving continuously in a loop so passengers step on and off without it stopping.
Paterson (Cape York) Telegraph Station
The Paterson Telegraph Station was the northernmost repeater station on Queensland's Cape York telegraph line, built in 1886–1887 where the submarine cable to Thursday Island came ashore.
Paterson (film)
Paterson is a 2016 drama film written and directed by Jim Jarmusch, starring Adam Driver as a bus driver and unpublished poet in Paterson, New Jersey.
Paterson (poem)
Paterson is William Carlos Williams's five-book modernist long poem (1946-1958) about Paterson, New Jersey, where a man mirrors the city; it follows the Passaic River and mixes verse, prose, and letters.
Paterson Joseph
Paterson Joseph (born 1964) is a British-Caribbean actor and author, LAMDA-trained and an RSC alumnus, best known as Alan Johnson in Peep Show, for The Leftovers and Wonka, and for his Sancho play and novel.
Paterson, New Jersey
Paterson, New Jersey: third-largest city in the state, founded 1792 by Hamilton's S.U.M. as America's first planned industrial city at the 77-foot Great Falls of the Passaic; 'Silk City,' locomotive center, WWII Heritage City.
Path (computing)
A path, also called a pathname or filepath, is a string that locates a file or directory in a hierarchical file system, with components separated by slashes or backslashes.
Path (graph theory)
In graph theory, a path is a walk in a graph that repeats no vertex and therefore no edge; a graph is connected when every pair of vertices has a path between them.
PATH (rail system)
PATH (Port Authority Trans-Hudson) is a rapid transit rail system operated by the Port Authority of New York and New Jersey, linking Manhattan with Newark, Jersey City, and Hoboken.
PATH (variable)
PATH is an environment variable on Unix and Unix-like operating systems holding a colon-separated list of directories that the shell searches, in order, for executable commands.
Path analysis (statistics)
Path analysis is a statistical method that decomposes correlations between variables into direct and indirect causal effects, estimated through simultaneous regression equations drawn as path diagrams.
Path computation element
A path computation element (PCE) is an entity, such as a router component or dedicated server, that computes constrained network paths, defined by the IETF in RFC 4655 in 2006.
Path decomposition
A path decomposition is a graph decomposition whose bags form a path; the minimum width over all such decompositions is the graph's pathwidth, the path-like analog of treewidth.
Path dependence
Path dependence: concept, also called lock-in or non-ergodic dynamics, describing processes whose outcomes hinge on contingent early events amplified by self-reinforcement; defined via contingency plus self-reinforcement, studied with Markov-chain models, and tested in fisheries and QWERTY research.
Path dependence of work
Path dependence of work is the principle in mechanics that work done by a force depends on the route taken, not just the start and end points.
Path graph
A path graph is a graph consisting of a single chain of vertices connected end-to-end, with no branches or cycles; the path on n vertices is written P_n.
Path integral formulation
The path integral formulation, also called the sum over histories, is a formulation of quantum mechanics, published by Richard Feynman in 1948, that sums a contribution from every path a particle can take.
Path integral molecular dynamics
Path integral molecular dynamics (PIMD) is a computer simulation method for equilibrium quantum properties, representing each particle as a ring polymer of beads joined by harmonic springs.
Path integral Monte Carlo
Path integral Monte Carlo is a quantum Monte Carlo method that computes finite-temperature properties of interacting quantum many-body systems by sampling particle paths in imaginary time.
Path integration
Path integration, also known as dead reckoning, is a navigation method in which an animal sums its movements into a home vector pointing back to its start.
Path of Exile
Path of Exile (流放之路) is a free-to-play online action RPG by New Zealand's Grinding Gear Games, released 23 October 2013, set in Wraeclast, known for its 1,500+ node passive skill tree, socketed skill gems, barter economy, and 13-week league cycle.
Path of Exile 2
Path of Exile 2 (PoE2) is Grinding Gear Games' free-to-play isometric action RPG sequel to Path of Exile, in paid Early Access since December 6, 2024 on PC, PS5, and Xbox Series X|S, with 12 classes, 36 ascendancies, and full 1.0 release set for December 11, 2026.
Path Robotics
Path Robotics is a Columbus, Ohio AI robotics company founded in 2018 by brothers Andy and Alex Lonsberry, building welding robots that need no programming.
Path tracing
Path tracing is a Monte Carlo rendering algorithm, introduced by James Kajiya in 1986, that traces random light paths from the camera to produce physically based, photorealistic images.
Path-connected space
A path-connected space is a topological space in which any two points can be joined by a continuous path. Every path-connected space is connected, but the converse fails.
Path-planning algorithm
A path-planning algorithm computes a collision-free route for a robot or agent from a start to a goal position. Main approaches include graph search such as A, sampling-based planners such as RRT, and potential fields.
Patha Sagauli Mound
Patha-Sagauli is a centrally protected archaeological site in Garautha tehsil, Jhansi district, Uttar Pradesh: ruins of a large Chandella temple containing a well preserved statue of Vishnu, listed by the ASI (N-UP-L135).
Pathaan (film)
Pathaan (पठान) is a 2023 Yash Raj Films Hindi action thriller directed by Siddharth Anand, starring Shah Rukh Khan, Deepika Padukone, and John Abraham; the fourth YRF Spy Universe film and then-record Rs 1,050 crore Hindi grosser.
Pathala Bhairavi (பாதாளபைரவி)
Pathala Bhairavi (పాతాళ భైరవి) is a 1951 Telugu-Tamil bilingual fantasy film directed by K. V. Reddy, starring N. T. Rama Rao and S. V. Ranga Rao, the first Telugu film to run 200 days.
