Spin (physics) Spin is an intrinsic form of angular momentum carried by elementary particles, and thus by composite particles such as hadrons, atomic nuclei, and atoms. [ 1][ 2]: 183 –184 Spin is quantized, and accurate models for the interaction with spin require relativistic quantum mechanics or quantum field theory .
v. t. e. Rotation around a fixed axis or axial rotation is a special case of rotational motion around an axis of rotation fixed, stationary, or static in three-dimensional space. This type of motion excludes the possibility of the instantaneous axis of rotation changing its orientation and cannot describe such phenomena as wobbling or precession.
Artificial gravity is the creation of an inertial force that mimics the effects of a gravitational force, usually by rotation. [ 1] Artificial gravity, or rotational gravity, is thus the appearance of a centrifugal force in a rotating frame of reference (the transmission of centripetal acceleration via normal force in the non-rotating frame of ...

Random cluster model. In statistical mechanics, probability theory, graph theory, etc. the random cluster model is a random graph that generalizes and unifies the Ising model, Potts model, and percolation model. It is used to study random combinatorial structures, electrical networks, etc. [1] [2] It is also referred to as the RC model or ...
Fidget spinner. A fidget spinner is a toy that consists of a ball bearing in the center of a multi-lobed (typically three-lobed) flat structure made from metal or plastic with metal weights in the lobes, designed to spin around its central axis. Fidget spinners became very prevalent trending toys in 2017. The toy has been promoted as helping ...
Spin model. A spin model is a mathematical model used in physics primarily to explain magnetism. Spin models may either be classical or quantum mechanical in nature. Spin models have been studied in quantum field theory as examples of integrable models. Spin models are also used in quantum information theory and computability theory in ...
"spinner" will have an interactive spinning wheel and a fidget spinner [125] which can be toggled via the switch. For the spinning wheel, a dropdown menu can change the number of numbers on the wheel: from 2 to 20. [126] Whereas for the fidget spinner, users have to mimic a rotating motion [125] in order for the spinner to spin.
