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:

    No sooner is your ocean filled, than he grumbles that it might have been of better vintage. Try him with half of a Universe, of an Omnipotence, he sets to quarrelling with the proprietor of the other half, and declares himself the most maltreated of men. Always there is a black spot in our sunshine: it is even as I said, the Shadow of Ourselves.
    Thomas Carlyle (1795–1881)

    Interpretation is the revenge of the intellect upon art. Even more. It is the revenge of the intellect upon the world. To interpret is to impoverish, to deplete the world—in order to set up a shadow world of “meanings.”
    Susan Sontag (b. 1933)

    But country folks who live beneath
    The shadow and the steeple;
    The parson and the parson’s wife,
    And mostly married people;
    Arthur Hugh Clough (1819–1861)
