Definition of Revolution


  1. The act of revolving, or turning round on an axis or a center; the motion of a body round a fixed point or line; rotation; as, the revolution of a wheel, of a top, of the earth on its axis, etc.
  2. Return to a point before occupied, or to a point relatively the same; a rolling back; return; as, revolution in an ellipse or spiral.
  3. The space measured by the regular return of a revolving body; the period made by the regular recurrence of a measure of time, or by a succession of similar events.
  4. The motion of any body, as a planet or satellite, in a curved line or orbit, until it returns to the same point again, or to a point relatively the same; -- designated as the annual, anomalistic, nodical, sidereal, or tropical revolution, according as the point of return or completion has a fixed relation to the year, the anomaly, the nodes, the stars, or the tropics; as, the revolution of the earth about the sun; the revolution of the moon about the earth.
  5.

  6. A total or radical change; as, a revolution in one's circumstances or way of living.

Revolution Quotations

The revolution is not an apple that falls when it is ripe. You have to make it fall.
Che Guevara

If you want to know the taste of a pear, you must change the pear by eating it yourself. If you want to know the theory and methods of revolution, you must take part in revolution. All genuine knowledge originates in direct experience.
Mao Zedong

If you go back to 1800, everybody was poor. I mean everybody. The Industrial Revolution kicked in, and a lot of countries benefited, but by no means everyone.
Bill Gates

Injustice, poverty, slavery, ignorance - these may be cured by reform or revolution. But men do not live only by fighting evils. They live by positive goals, individual and collective, a vast variety of them, seldom predictable, at times incompatible.
Isaiah Berlin

Let the ruling classes tremble at a communist revolution. The proletarians have nothing to lose but their chains. They have a world to win. Workingmen of all countries, unite!
