In electronics, based on or consisting chiefly or exclusively of semiconducting materials, components, and related devices.

→ solid; → state.

The branch of condensed matter physics concerned with the study of rigid matter or solids in terms of their constituent particles (electrons and nuclei). The bulk of solid-state physics theory and research is focused on the electromagnetic, thermodynamic, and structural properties of crystalline solids.

→ solid state; → physics.

1a) The → condition of a → system characterized by a particular set of values for its properties.
1b) The → phase of matter; → solid, → liquid, or → gas.

2a) To declare definitely or specifically.
2b) To set forth formally in speech or writing (to state a hypothesis).
2c) To set forth in proper or definite form (Dictionary.com).

M.E. stat, partly from M.Fr. estat, partly from L. status "manner of standing, position, condition," noun of action from p.p. stem of stare "to stand;" cognate with Pers. istâdan "to stand," as below.
The sense of "declare in words" (1640s) comes from the notion of "placing (something on the record), setting in a position."

Estât, from istâdan "to stand;" Mid.Pers. êstâtan; O.Pers./Av. sta- "to stand, stand still; to set" (Sogd. ôštât "to stand"); Av. hištaiti; cf. Skt. sthâ- "to stand;" Gk. histemi "put, place, weigh," stasis "a standing still;" L. stare "to stand;" Lith. statau "place;" Goth. standan; PIE base *sta- "to stand"); hâlat, from Ar. Hâlat "state, quality."

1) Something stated.
2) A communication or declaration in speech or writing, setting forth facts, particulars, etc.
3) A single sentence or assertion (Dictionary.com).

Verbal noun of → state (v.)

A person who is experienced in the art of government or versed in the administration of government affairs (Dictionary.com).

From state's man, translation of Fr. homme d'Etat; → state; → man.

A → cosmological model according to which the → Universe has no beginning and no end and maintains the same mean density, in spite of its observed expansion, by the continual creation of matter throughout all space. The theory was first put forward by Sir James Jeans in about 1920 and again in revised form in 1948 by Hermann Bondi and Thomas Gold. It was further developed by Sir Fred Hoyle to deal with problems that had arisen in connection with the alternative → Big Bang model. Observations since the 1950s have produced much evidence contradictory to the steady state theory and supportive of the Big Bang model. More specifically, the steady state theory attributed the → cosmic microwave background to → thermal radiation from → dust clouds, but this cannot account for a single → blackbody spectrum. Moreover, the steady state theory lacked a plausible mechanism for the creation of matter in space. See also → perfect cosmological principle.

→ steady; → state; → theory.

The electronic state of an atom or molecule which has two unpaired electrons, and therefore whose total spin angular momentum is equal to 1.

→ triplet; → state.

In thermodynamics, a generalized → equation of state obtained when the → compression factor Z is expanded in terms of a power series, e.g.: Z = 1 + B(T) / V_m + C(T) / V_m² + ...

→ virial; → equation of state.
