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:
“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)
“It is not much matter which we say, but mind, we must all say the same.”

“Trying to love your children equally is a losing battle. Your children’s scorecards will never match your own. No matter how meticulously you measure and mete out your love and attention, and material gifts, it will never feel truly equal to your children. . . . Your children will need different things at different times, and true equality won’t really serve their different needs very well, anyway.”
—Marianne E. Neifert (20th century)
