Shadow

Shadow

A shadow is an area where direct light from a light source cannot reach due to obstruction by an object. It occupies all of the space behind an opaque object with light in front of it. The cross section of a shadow is a two-dimensional silhouette, or reverse projection of the object blocking the light. The sun causes many objects to have shadows and at certain times of the day, when the sun is at certain heights, the lengths of shadows change.

Famous quotes containing the word shadow:

    O love, my love! if I no more should see
    Thyself, nor on the earth the shadow of thee,
    Nor image of thine eyes in any spring,—
    How then should sound upon Life’s darkening slope
    The ground-whirl of the perished leaves of Hope,
    The wind of Death’s imperishable wing?
    Dante Gabriel Rossetti (1828–1882)

    A perfect beauty of a sunflower! a perfect excellent lovely
    sunflower existence! a sweet natural eye to the new hip moon, woke up alive and excited grasping in the sunset shadow sunrise golden monthly breeze!
    Allen Ginsberg (b. 1926)

    After Buddha was dead, his shadow was still shown for centuries in a cave—a tremendous, gruesome shadow. God is dead; but given the way of man, there may still be caves for thousands of years in which his shadow will be shown.—And we—we still have to vanquish his shadow, too.
    Friedrich Nietzsche (1844–1900)
