20. n. A body which throughout its mass (and not merely at its surface) resists for an indefinite time a sufficiently small force that tends to alter its equilibrium figure, always springing back into shape after the force is removed; a body possessing elasticity of figure. Every such body has limits of elasticity, and, if subjected to a strain exceeding these limits, it takes a set and does not return to its original shape on being let go. This property is called plasticity. The minimum energy required to give a set to a body of definite form and size measures its resilience. When the resilience of a body is small and masks its springiness, the body is called soft. Even fluids transmit shearing forces if time be allowed, and many substances will yield indefinitely to very small (but not indefinitely small) forces applied for great lengths of time. So solids that have received a small set will sometimes partially recover their figures after a long time. This property in fluids is called viscosity, in solids after-effect (German nachwirkung). The phenomenon is connected with a regrouping of the molecules, and indicates the essential difference between a solid and a liquid. In fluids diffusion is continually active, and in gases it produces phenomena of viscosity. In liquids it is not rapid enough to give rise to sensible viscosity, but the free motion of the molecules makes the body fluid, while the tendency of sets of molecules to continue for a while associated makes the fluidity imperfect. In solids, on the other hand (at least when not under strain), there is no diffusion, and the molecules are consequently in stationary motion or describing quasi-orbits. They thus become grouped in the mode in which they have least positional energy consistent with their kinetic energy. When this grouping is slightly disturbed, it tends to restore itself; but when the disturbance is greater, some of the molecules will tend to return to their old places and others to move on to new situations, and this may give rise to a new permanent grouping, and exhibit the phenomenon of plasticity. But if not quite sufficient for this, disturbances of the molecular motions somewhat similar to the secular perturbations of the planets will result, from which there will be no restoration for a very long time. Solid bodies are very strongly cohesive, showing that the molecules attract one another on the whole; and they are generally capable of crystallization, showing that the attractions of the molecules are different in different directions.
21. n. In geometry, a body or magnitude which has three dimensions—length, breadth, and thickness—being thus distinguished from a surface, which has but two dimensions, and from a line, which has but one. The boundaries of solids are surfaces. Besides the three round bodies (the sphere, cone, and cylinder), together with the conoids, and the pyramids, prisms, and prismatoids, the most important geometrical solids are the five Platonic and the Kepler-Poinsot regular polyhedra, the two semi-regular solids, and the thirteen Archimedean solids. The faces, edges, or summits of one solid are said to correspond with the faces, edges, or summits of another when the radii from the center of the former to the mid-faces, mid-edges, or summits can be simultaneously brought into coincidence with the radii from the center to the mid-faces, mid-edges, or summits of the latter. If two solids correspond faces to summits, summits to faces, and edges to edges, they are said to be reciprocal. If to the edges of one solid correspond the faces or summits of another, while to the faces and summits together of the former correspond the summits or faces of another, the latter is said to be the summital or facial holohedron of the former. The regular tetrahedron is the reciprocal of itself, and its reciprocal holohedra are the cube and octahedron. The reciprocal holohedra of these, again, are the semi-regular dodecahedron and the cuboctahedron. The facial holohedron of these, again, is the small rhombicuboctahedron. The faces of the truncated cube and truncated octahedron correspond to those of the cuboctahedron. The snub-cube has faces corresponding to the cuboctahedron, and twenty-four faces which in two sets of twelve correspond to the summits of two other cuboctahedra. The faces of the great rhombicuboctahedron correspond to those of the small rhombicuboctahedron. Just as the cube and octahedron are reciprocal, so likewise are the Platonic dodecahedron and icosahedron, though they are related to no hemihedral body like the tetrahedron. Their reciprocal holohedra are the semi-regular triacontahedron and the icosidodecahedron, and the facial holohedron of these, again, is the small rhombicosidodecahedron. The faces of the truncated dodecahedron and truncated icosahedron correspond to those of the icosidodecahedron. The snubdodecahedron has faces corresponding to those of the icosidodecahedron, and two sets of others corresponding to the summits of two other icosidodecahedra. The faces of the great rhombicosidodecahedron correspond to those of the small rhombicosidodecahedron. The faces, summits, and edges of the great icosahedron and great stellated dodecahedron correspond respectively to the faces, summits, and edges of the Platonic dodecahedron and icosahedron. The great dodecahedron and small stellated dodecahedron are self-reciprocal, both faces and summits corresponding to the faces of the Platonic dodecahedron or summits of the icosahedron. The faces of the truncated tetrahedron correspond to the faces of the octahedron or summits of the cube.
22. n. plural In anatomy, all parts of the body which are not fluid: as, the solids and fluids of the body.
23. n. plural In printing, the parts of an engraving which show black or solid in print.
24. Of uniform color; self-colored: a pigeon-fanciers' term.
