Differential Geometry of Curves/frenet-serret Formulas

Famous quotes containing the words differential, geometry, curves and/or formulas:

    But how is one to make a scientist understand that there is something unalterably deranged about differential calculus, quantum theory, or the obscene and so inanely liturgical ordeals of the precession of the equinoxes.
    Antonin Artaud (1896–1948)

    The geometry of landscape and situation seems to create its own systems of time, the sense of a dynamic element which is cinematising the events of the canvas, translating a posture or ceremony into dynamic terms. The greatest movie of the 20th century is the Mona Lisa, just as the greatest novel is Gray’s Anatomy.
    —J.G. (James Graham)

    For a hundred and fifty years, in the pasture of dead horses,
    roots of pine trees pushed through the pale curves of your ribs,
    yellow blossoms flourished above you in autumn, and in winter
    frost heaved your bones in the ground—old toilers, soil makers:
    O Roger, Mackerel, Riley, Ned, Nellie, Chester, Lady Ghost.
    Donald Hall (b. 1928)

    It is sentimentalism to assume that the teaching of life can always be fitted to the child’s interests, just as it is empty formalism to force the child to parrot the formulas of adult society. Interests can be created and stimulated.
    Jerome S. Bruner (20th century)
