Double Pendulum

In physics and mathematics, in the area of dynamical systems, a double pendulum is a pendulum with another pendulum attached to its end, and is a simple physical system that exhibits rich dynamic behavior with a strong sensitivity to initial conditions. The motion of a double pendulum is governed by a set of coupled ordinary differential equations. For certain energies its motion is chaotic.

Famous quotes containing the words double and/or pendulum:

    Go; and if that word have not quite killed thee,
    Ease me with death by bidding me got too.
    Oh, if it have, let my word work on me,
    And a just office on a murderer do.
    Except it be too late to kill me so,
    Being double dead: going, and bidding go.
    John Donne (1572–1631)

    The pendulum oscillates between these two terms: Suffering—that opens a window on the real and is the main condition of the artistic experience, and Boredom ... that must be considered as the most tolerable because the most durable of human evils.
    Samuel Beckett (1906–1989)
