Inverse-square Law - Field Theory Interpretation

Field Theory Interpretation

For an irrotational vector field in three-dimensional space the inverse-square law corresponds to the property that the divergence is zero outside the source. This can be generalized to higher dimensions. Generally, for an irrotational vector field in n-dimensional Euclidean space, the intensity "I" of the vector field falls off with the distance "r" following the inverse (n − 1)th power law

,

given that the space outside the source is divergence free.

Famous quotes containing the words field and/or theory:

    The little toy dog is covered with dust,
    But sturdy and stanch he stands;
    And the little toy soldier is red with rust,
    And the musket moulds in his hands.
    Time was when the little toy dog was new,
    And the soldier was passing fair;
    And that was the time when our Little Boy Blue
    Kissed them and put them there.
    —Eugene Field (1850–1895)

    Psychotherapy—The theory that the patient will probably get well anyway, and is certainly a damned ijjit.
    —H.L. (Henry Lewis)
