Same as → Einstein model.

→ Einstein; → solid.

1) A body or object having → three  → dimensions (length, breadth, and thickness). Of or pertaining to bodies or figures of three dimensions.
2) One of the four main → states of → matter, in which the substance molecules vibrate about fixed positions. Unlike a gas or liquid, a solid has a fixed shape, and unlike a gas, a solid has a fixed volume.
3) Without holes, free from cavities, not hollow.
4) Dense, thick, or heavy in nature or appearance.
5) Reliable; that can be depended upon.

M.E., from O.Fr. solide "firm, dense, compact," from L. solidus "firm, whole, entire," from PIE base *sol- "whole;" cf. Mod.Pers. har "every, all, each, any;" O.Pers. haruva- "whole, all together;" Av. hauruua- "whole, at all, undamaged;" Skt. sárva- "whole, all, every, undivided;" Gk. holos "whole, complete;" L. salvus "whole, safe, healthy," sollus "whole, entire, unbroken."

Dafzé, from dafzak "big, gross, thick, hard" (Dehxodâ), variant dabz "thick, coarse," → concentrated; cf. Ossetic baezgin "thick, dense;" Shughni divask, Oroshori devaskak "calf of the leg;" Khotanese baysga- "thick, deep, many, large;" Sogd. δβânz "wide, coarse;" Av. bəzuuant- "thick, dense," bazah- "thickness;" Proto-Ir. *(d)banz- "to be(come) thick, dense;" cf. Gk. pakhos "thickness, coarseness;" Latvian biezs "thick" (Cheung 2007).

The figure formed by three or more planes meeting at a common point or formed at the vertex of a cone. The solid angle completely surrounding a point is 4π steradian. → steradian.

→ solid; → angle.

Zâviyé, → angle; fazâyi "of or relating to space," → space; jâmed, → solid.

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.

1) To become or make solid, hard, or firm.

→ solid; → -fy.

1) To become or make solid, hard, or firm.

→ solid; → -fy.

The state, property, or quality of being solid. Solidness.

→ solid; → -ity.

In the → phase diagram of a → mixture at constant pressure, (such as an → alloy), the → curve that separates the → liquid+solid → phase from the all solid phase. Above the solidus some or all of the mixture will be in a liquid state. See also → liquidus.

From L. solidus, → solid.
