In physics, a charged particle is a particle with an electric charge. It may be either a subatomic particle or an ion. A collection of charged particles, or even a gas containing a proportion of charged particles, is called a plasma, which is called the fourth state of matter because its properties are quite different from solids, liquids and gases (plasma is the most common state of matter in the universe). Particles either have a positive, negative or no charge (being neutral).
Their effects go beyond the laboratory (see aurora borealis).
Famous quotes containing the words charged and/or particle:
“God, who gave to him the lyre,
Of all mortals the desire,
For all breathing men’s behoof,
Straitly charged him, “Sit aloof;”
Annexed a warning, poets say,
To the bright premium,—
Ever, when twain together play,
Shall the harp be dumb.”
—Ralph Waldo Emerson (1803–1882)
“Standing on the bare ground,—my head bathed by the blithe air, and uplifted into infinite space,—all mean egotism vanishes. I become a transparent eye-ball; I am nothing; I see all; the currents of the Universal Being circulate through me; I am part and particle of God.”
—Ralph Waldo Emerson (1803–1882)
