Matter
Matter is generally considered to be a substance (often a particle) that has rest mass and (usually) also volume. The volume is determined by the three-dimensional space it occupies, while the mass is defined by the usual ways that mass is measured (see the article on mass). Matter is also a general term for the substance of which all observable physical objects consist.

Famous quotes containing the word matter:
“How do you know what the world is like? Do you know the world is a foul sty? Do you know if you rip the fronts off houses you’d find swine? The world is a hell. What does it matter what happens in it?”
—Thornton Wilder (1897–1975)
“If your mother tells you to do a thing, it is wrong to reply that you won’t. It is better and more becoming to intimate that you will do as she bids you, and then afterwards act quietly in the matter according to the dictates of your better judgment.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“It is a matter of perfect indifference where a thing originated; the only question is: “Is it true in and for itself?””
—Georg Wilhelm Friedrich Hegel (1770–1831)
