Matter

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:

    No matter how calmly you try to referee, parenting will eventually produce bizarre behavior, and I’m not talking about the kids. Their behavior is always normal.
    Bill Cosby (b. 1937)

    My first big mistake was made when, in a moment of weakness, I consented to learn the game; for a man who can frankly say “I do not play bridge” is allowed to go over in the corner and run the pianola by himself, while the poor neophyte, no matter how much he may protest that he isn’t “at all a good player, in fact I’m perfectly rotten,” is never believed, but dragged into a game where it is discovered, too late, that he spoke the truth.
    Robert Benchley (1889–1945)

    It doesn’t matter whether you’re talking about bombs or the intelligence quotients of one race as against another ... if a man is a scientist, like me, he’ll always say “Publish and be damned.”
    Jacob Bronowski (1908–1974)
