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:
“But, though light-headed man forget,
Remembering Matter pays her debt:
Still, through her motes and masses, draw
Electric thrills and ties of Law,
Which bind the strengths of Nature wild
To the conscience of the child.”
—Ralph Waldo Emerson (1803–1882)
“One of the most significant effects of age-segregation in our society has been the isolation of children from the world of work. Whereas in the past children not only saw what their parents did for a living but even shared substantially in the task, many children nowadays have only a vague notion of the nature of the parent’s job, and have had little or no opportunity to observe the parent, or for that matter any other adult, when he is fully engaged in his work.”
—Urie Bronfenbrenner (b. 1917)
“In the best of all possible worlds, childbirth enriches a marriage. In the worst, it harms it. No matter how good their marriage is, most couples find that having a baby challenges their relationship.”
—Jean Marzollo (20th century)
