Pitch Drop Experiment

The pitch drop experiment is a long-term experiment which measures the flow of a piece of pitch over many years. Pitch is the name for any of a number of highly viscous liquids which appear solid, most commonly bitumen. At room temperature, tar pitch flows at a very slow rate, taking several years to form a single drop.

Famous quotes containing the words pitch, drop and/or experiment:

    I dream that I have brought
    To such a pitch my thought
    That coming time can say,
    “He shadowed in a glass
    What thing her body was.”
    William Butler Yeats (1865–1939)

    O make harmonious mix of voice and string
    To him by whom the skies with clouds are lin’d;
    By whom the rain, from clouds to drop assign’d,
    Supples the clods of summer-scorched fields,
    —Bible: Hebrew Psalm CXLVII (Paraphrased by The Countess of Pembroke)

    To me the sole hope of human salvation lies in teaching Man to regard himself as an experiment in the realization of God, to regard his hands as God’s hand, his brain as God’s brain, his purpose as God’s purpose. He must regard God as a helpless Longing, which longed him into existence by its desperate need for an executive organ.
    George Bernard Shaw (1856–1950)
