Wick Rotation

In physics, Wick rotation, named after Gian-Carlo Wick, is a method of finding a solution to a mathematical problem in Minkowski space from a solution to a related problem in Euclidean space by means of a transformation that substitutes an imaginary-number variable for a real-number variable. This transformation is also used to find solutions to problems in quantum mechanics and other areas.

Famous quotes containing the words wick and/or rotation:

    A revolutionary poem will not tell you who or when to kill, what and when to burn, or even how to theorize. It reminds you ... where and when and how you are living and might live—it is a wick of desire.
    Adrienne Rich (b. 1929)

    The lazy manage to keep up with the earth’s rotation just as well as the industrious.
    Mason Cooley (b. 1927)
