Solid
Solid is one of the four fundamental states of matter (the others being liquid, gas, and plasma). It is characterized by structural rigidity and resistance to changes of shape or volume. Unlike a liquid, a solid object does not flow to take on the shape of its container, nor does it expand to fill the entire volume available to it like a gas does. The atoms in a solid are tightly bound to each other, either in a regular geometric lattice (crystalline solids, which include metals and ordinary water ice) or irregularly (an amorphous solid such as common window glass).

Famous quotes containing the word solid:
“Without [diversion] we would be in a state of weariness, and this weariness would spur us on to seek a more solid means of escaping from it. But diversion amuses us, and leads us unconsciously to death.”
—Blaise Pascal (1623–1662)
“We have the pleasures suitable to our lot; let us not usurp those of greatness. Ours are more natural and all the more solid and sure for being humbler. Since we will not do so out of conscience, at least out of ambition let us reject ambition.”
—Michel de Montaigne (1533–1592)
“Miss Western: Tell me, child, what objections can you have to the young gentleman?
Sophie: A very solid objection, in my opinion. I hate him.
Miss Western: Well, I have known many couples who have entirely disliked each other, lead very comfortable, genteel lives.”
—John Osborne (1929–1994)
