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:

    In order to be somebody you have to hold even your shadow in high regard.
    Friedrich Nietzsche (1844–1900)

    Yet there is a mystery here and it is not one that I understand: without the sting of otherness, of—even—the vicious, without the terrible energies of the underside of health, sanity, sense, then nothing works or can work. I tell you that goodness-what we in our ordinary daylight selves call goodness: the ordinary, the decent—these are nothing without the hidden powers that pour forth continually from their shadow sides. Their hidden aspects contained and tempered.
    Doris Lessing (b. 1919)

    Mark where the pressing wind shoots javelin-like
    Its skeleton shadow on the broad-backed wave!
    Here is a fitting spot to dig Love’s grave;
    George Meredith (1828–1909)
