2. Doublet–triplet splitting problem - Wikipedia

   en.wikipedia.org/wiki/Doublet–triplet_splitting...

   In particle physics, the doublet–triplet (splitting) problem is a problem of some Grand Unified Theories, such as SU(5), SO(10), and . Grand unified theories predict Higgs bosons (doublets of S U ( 2 ) {\displaystyle SU(2)} ) arise from representations of the unified group that contain other states, in particular, states that are triplets of ...

3. Doublet state - Wikipedia

   en.wikipedia.org/wiki/Doublet_state

   In quantum mechanics, a doublet is a composite quantum state of a system with an effective spin of 1/2, such that there are two allowed values of the spin component, −1/2 and +1/2. Quantum systems with two possible states are sometimes called two-level systems .

4. Word ladder - Wikipedia

   en.wikipedia.org/wiki/Word_ladder

   Word ladder (also known as Doublets, [1] word-links, change-the-word puzzles, paragrams, laddergrams, [2] or word golf) is a word game invented by Lewis Carroll. A word ladder puzzle begins with two words, and to solve the puzzle one must find a chain of other words to link the two, in which two adjacent words (that is, words in successive ...

5. Triplet state - Wikipedia

   en.wikipedia.org/wiki/Triplet_state

   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".

6. Multiplicity (chemistry) - Wikipedia

   The triplet consists of three states with spin components +1, 0 and –1 along the direction of the total orbital angular momentum, which is also 1 as indicated by the letter P. The total angular momentum quantum number J can vary from L+S = 2 to L–S = 0 in integer steps, so that J = 2, 1 or 0.

7. Doublet (linguistics) - Wikipedia

   Most simply, a native word can at some point split into two distinct forms, staying within a single language, as with English too which split from to. [3] Alternatively, a word may be inherited from a parent language, and a cognate borrowed from a separate sister language. In other words, one route was direct inheritance, while the other route ...

   Triplets Janie, Wright and Luke Hilbert found out their birth order on their 18th birthday in a moment shared on TikTok. Their parents explain to TODAY.com why they waited to tell them.

9. Word problem (mathematics) - Wikipedia

   en.wikipedia.org/wiki/Word_problem_(mathematics)

   The word problem for an algebra is then to determine, given two expressions (words) involving the generators and operations, whether they represent the same element of the algebra modulo the identities. The word problems for groups and semigroups can be phrased as word problems for algebras. [1]
