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:
“Now, we deny not, but that politicians may sometimes abuse religion, and make it serve for the promoting of their own private interests and designs; which yet they could not do so well neither, were the thing itself a mere cheat and figment of their own, and had no reality at all in nature, nor anything solid at the bottom of it.”
—Ralph J. Cudworth (1617–1688)
“Children can’t make their own rules and no child is happy without them. The great need of the young is for authority that protects them against the consequences of their own primitive passions and their lack of experience, that provides with guides for everyday behavior and that builds some solid ground they can stand on for the future.”
—Leontine Young (20th century)
“It has often been a solid Grief to me, when I have reflected on this glorious Nation, which is the Scene of publick Happiness and Liberty, that there are still Crowds of private Tyrants, against whom there neither is any Law now in Being, nor can there be invented any by the Wit of Man. These cruel Men are ill-natured husbands.”
—Richard Steele (1672–1729)
