In ring theory, a branch of abstract algebra, a **prime ring** is a specific type of ring with certain properties that resemble those of prime numbers in number theory. A ring \( R \) is called **prime** if it is not the zero ring (i.e.
In mathematics, particularly in the field of functional analysis and the study of operator algebras, a *quasiregular element* typically refers to an element of a Banach algebra or a more general algebraic structure that behaves somewhat like an invertible element, but not quite.
The Skewb Ultimate is a three-dimensional mechanical puzzle and a twisty puzzle similar to the traditional Skewb. It is a variation that features a more complex mechanism and additional colors, making it more challenging to solve. The Skewb Ultimate is characterized by its unique design, where it can twist in multiple directions, and each face can be turned independently.
SUNMOS (Sun Microsystems Multi Operating System) is a distributed operating system developed by Sun Microsystems in the late 1980s and early 1990s. It was designed for networked systems and aimed to facilitate resource sharing and communication between computers. SUNMOS is notable for its use in supporting a variety of hardware configurations and providing a platform for distributed computing environments. It included features that allowed multiple users and applications to access shared resources efficiently.
A 1:25 scale model means that the model is 1/25th the size of the actual object it represents. In other words, for every 25 units of measurement of the real object, the model is 1 unit of measurement. This scale is commonly used for a variety of model types, including automobiles, architecture, and dioramas.
The 1:144 scale is a common scale used in modeling, where 1 unit of measurement on the model (such as an inch or centimeter) represents 144 of the same units in reality. This means that the model is 1/144th the size of the actual object it represents. For example, if a real aircraft is 144 feet long, in a 1:144 scale model, it would be 1 foot long.
A 1:35 scale refers to a scale model where one unit of measurement in the model (such as inches or centimeters) is equivalent to 35 of the same units in the real object. For example, if a model is 1:35 scale, and a real tank is 3.5 meters long, the model would be approximately 10 centimeters (or about 3.9 inches) long.
Chaotic scattering refers to a phenomenon in dynamical systems, particularly in the context of scattering processes, where the trajectories of particles become highly sensitive to initial conditions due to the underlying chaotic dynamics of the system. In chaotic scattering, small changes in the initial conditions of incoming particles can lead to vastly different scattering outcomes.
