Pattern
A pattern is an arrangement of shapes, numbers, or other elements that follows a rule, so it can be continued or reproduced from the rule itself.
Pattern language (formal languages)
A pattern language, also called an Angluin pattern language, is the set of words generated from a pattern by substituting words for its variables, introduced by Dana Angluin in 1980.
Pattern scaling
Pattern scaling is a climate-modeling approximation in which the regional pattern of climate change is assumed constant and scaled linearly with global mean warming, first proposed by Santer et al. in 1990.
Pattern search (optimization)
Pattern search is a family of derivative-free direct search methods for nonlinear optimization that probes fixed directions with an adaptive step size, accepting steps only when the objective improves.
Patterned ground
Patterned ground is ground displaying regular geometric shapes such as circles, polygons, nets, steps, and stripes, produced by frost action in cold climates; similar polygons also occur on Mars.
Patterson method
The Patterson method is a crystallographic technique introduced by Arthur Lindo Patterson in 1934 that derives structural information from X-ray diffraction data without requiring lost phase information.
Paul A. Mayewski
Paul A. Mayewski, born 1946, is an American glaciologist and polar explorer who directed the Climate Change Institute at the University of Maine and led more than 60 polar expeditions.
Paul A. Smith (American topologist)
Paul Althaus Smith (1900–1980) was an American topologist at Columbia University whose Smith theory of fixed points of periodic transformations and Smith conjecture founded the study of group actions in topology.
Paul A. Wender
Paul A. Wender is an American organic and medicinal chemist, the Francis W. Bergstrom Professor of Chemistry at Stanford University, known for function-oriented synthesis and practical syntheses of bryostatin 1 and prostratin.
