Origami artists are individuals who practice the art of origami, which is the Japanese tradition of paper folding. This art form involves transforming a flat sheet of paper into a finished sculpture through folding techniques, without the use of cuts or glue. Origami artists can create a wide range of designs, from simple shapes like cranes and boats to complex structures that may require advanced techniques and multiple sheets of paper.

"Bug Wars" could refer to different concepts depending on the context, such as a video game, educational tool, or a themed event. One notable context is a video game that involves strategy and simulation elements where players control various insect species to battle against each other. The gameplay often includes resource management, battling mechanics, and evolving species to gain strategic advantages.

A list of origamists would typically include individuals known for their contributions to the art of origami, either as artists, designers, or scholars. These origamists may be famous for creating original designs, developing new techniques, or promoting the art of paper folding through education and workshops.

Matthew T. Mason is likely a reference to a specific individual, but without additional context, it is difficult to provide precise information. Matthew T. Mason could be a figure in academia, science, technology, or perhaps even literature or other fields. If you have a particular context or domain in mind (e.g., a specific profession or contribution), please provide more details for a more accurate response.

Pureland origami is a style of origami that emphasizes folds that can be made using only straight valley and mountain folds while avoiding complex techniques such as reverse folds, twist folds, and many other advanced techniques. This approach is designed to make origami more accessible, especially for beginners or those with physical limitations. In Pureland origami, the instructions are typically clear and straightforward, using simple terminology and notations.

Washi is a traditional Japanese paper known for its unique texture, strength, and versatility. It is made from the fibers of plants such as the gampi tree, the mitsumata shrub, or the paper mulberry. The production of washi involves a labor-intensive process that includes hand-pulping and hand-pouring the paper, resulting in a product that is both highly decorative and functional.

Orthogonal coordinate systems are systems used to define a point in space using coordinates in such a way that the coordinate axes are perpendicular (orthogonal) to each other. In these systems, the position of a point is determined by a set of values, typically referred to as coordinates, which indicates its distance from the axes.

Bessel polynomials are a series of orthogonal polynomials that are related to Bessel functions, which are solutions to Bessel's differential equation. The Bessel polynomials, denoted usually by \( P_n(x) \), are defined using the formula: \[ P_n(x) = \sum_{k=0}^{n} \binom{n}{k} \frac{(-1)^k}{k!} (x/2)^k.

The Mehler kernel is a function that arises in the context of orthogonal polynomials, particularly in relation to the theory of Hermite polynomials and the heat equation. It plays a significant role in probability theory, mathematical physics, and the study of stochastic processes.

Continuous \( q \)-Laguerre polynomials are a family of orthogonal polynomials that generalize the classical Laguerre polynomials by incorporating the concept of \( q \)-calculus, which deals with discrete analogs of calculus concepts. These polynomials arise in various areas of mathematics and physics, including approximation theory, special functions, and quantum mechanics.

"Space by century" could refer to various interpretations, such as the history of space exploration, the development of astronomical knowledge, or the evolution of concepts regarding space in human thought and culture.

Gegenbauer polynomials, denoted as \( C_n^{(\lambda)}(x) \), are a family of orthogonal polynomials that generalize Legendre polynomials and Chebyshev polynomials. They arise in various areas of mathematics and are particularly useful in solving problems involving spherical harmonics and certain types of differential equations.

Hahn polynomials are a class of orthogonal polynomials that arise in the context of the theory of orthogonal polynomials on discrete sets. They are named after the mathematician Wolfgang Hahn, who introduced them in the early 20th century. Hahn polynomials are defined for a discrete variable and are often associated with certain types of hypergeometric functions.

Pseudo-Jacobi polynomials are a class of orthogonal polynomials that are related to the Jacobi polynomials but have some distinct characteristics or domains of applicability. The term "pseudo" typically refers to modifications or generalizations of well-known polynomial families that maintain certain properties or introduce new variables.

The Q-Hahn polynomials are a family of orthogonal polynomials that arise in the context of basic hypergeometric functions and q-series. They are a specific case of the more general class of q-polynomials, which are related to the theory of partition and combinatorics, as well as to special functions in mathematical physics.

Q-Racah polynomials are a class of orthogonal polynomials that arise in the context of the theory of special functions and are associated with the asymptotic theory of orthogonal polynomials. They are a generalization of the Racah polynomials and belong to the family of basic hypergeometric orthogonal polynomials.

OS/2 is an operating system that was originally developed by IBM and Microsoft in the late 1980s. It was designed to be a robust, multitasking operating system for personal computers, especially for business and enterprise use. Although Microsoft eventually exited the OS/2 project to focus on Windows, IBM continued to develop OS/2 into the 1990s.

OS/2, which stands for Operating System/2, is a computer operating system developed by IBM in the late 1980s. Originally created as a successor to DOS, OS/2 was intended to provide a stable and capable environment for running applications in a multitasking and multiuser setting. It was co-developed with Microsoft initially, but after version 1.3, IBM took over development completely.

OS/2 drivers are software components that allow the OS/2 operating system to communicate with hardware devices and facilitate their functioning. OS/2, developed by IBM, is a multi-tasking operating system that was originally designed for personal computers, and it supports a variety of hardware components, including printers, network cards, storage devices, and graphics adapters.

ArcaOS is an operating system that is a modernized version of IBM's OS/2, which was originally developed in the 1980s as a joint project between IBM and Microsoft. ArcaOS is produced by Arca Noae, a company that aims to revive and support the legacy of OS/2 and its applications.
