In object-oriented programming, the singleton pattern is a software design pattern that restricts the instantiation of a class to a singular instance. It is one of the well-known "Gang of Four" design patterns , which describe how to solve recurring problems in object-oriented software. [ 1 ]

Examples of atoms in singlet, doublet, and triplet states. In quantum mechanics, a triplet state, or spin triplet, is the quantum state of an object such as an electron, atom, or molecule, having a quantum spin S = 1. It has three allowed values of the spin's projection along a given axis m S = −1, 0, or +1, giving the name "triplet".
A sleeveless T-shirt, also called a muscle shirt, is the same design as a T-shirt, but without sleeves. [4] Some sleeveless T-shirts, which possess smaller, narrower arm holes, are traditionally worn by both women and men. They are often worn during athletic activities or as casual wear during warmer weather.
Figure 2: Pseudoscalar mesons of spin-0 form a nonet Figure 3: Vector mesons of spin-1 form a nonet. The Eightfold Way classification is named after the following fact: If we take three flavors of quarks, then the quarks lie in the fundamental representation, 3 (called the triplet) of flavor SU(3).
The ability of positronium to form both singlet and triplet states is described mathematically by saying that the product of two doublet representations (meaning the electron and positron, which are both spin-1/2 doublets) can be decomposed into the sum of an adjoint representation (the triplet or spin 1 state) and a trivial representation (the ...
