Bucket Argument

Isaac Newton's rotating bucket argument (also known as "Newton's bucket") was designed to demonstrate that true rotational motion cannot be defined as the relative rotation of the body with respect to the immediately surrounding bodies. It is one of five arguments from the "properties, causes, and effects" of true motion and rest that support his contention that, in general, true motion and rest cannot be defined as special instances of motion or rest relative to other bodies, but instead can be defined only by reference to absolute space. Alternatively, these experiments provide an operational definition of what is meant by "absolute rotation", and do not pretend to address the question of "rotation relative to what?".

Famous quotes containing the words bucket and/or argument:

    And now, far removed from the loved habitation,
    The tear of regret will intrusively swell,
    As fancy reverts to my father’s plantation,
    And sighs for the bucket that hung in the well.
    Samuel Woodworth (1788–1842)

    The argument ad feminam, all the old knives
    that have rusted in my back, I drive in yours,
    ma semblable, ma soeur!
    Adrienne Rich (b. 1929)
