Benedetto Castelli - Works

Works

He published Mensuration of Running Water, an important work on fluids in motion, and then his Geometrical Demonstrations of the Measure of Running Waters in which the publishing notes described him as Abbot of Cassina and Mathematician to Pope Urban VIII, once a supporter of his mentor, Galileo.

He dedicated both publications to "the most Illustrious, and most Excellent Prince", Taddeo Barberini, a nephew of Pope Urban. In reality, Barberini was neither; he had appointed himself "Prince" of the Palestrina comune bought by the Barberini family and was "illustrious" because he had amassed great wealth during his uncle's reign as Pope.

Famous quotes containing the word works:

    There is a great deal of self-denial and manliness in poor and middle-class houses, in town and country, that has not got into literature, and never will, but that keeps the earth sweet; that saves on superfluities, and spends on essentials; that goes rusty, and educates the boy; that sells the horse, but builds the school; works early and late, takes two looms in the factory, three looms, six looms, but pays off the mortgage on the paternal farm, and then goes back cheerfully to work again.
    Ralph Waldo Emerson (1803–1882)

    Reason, the prized reality, the Law, is apprehended, now and then, for a serene and profound moment, amidst the hubbub of cares and works which have no direct bearing on it;Mis then lost, for months or years, and again found, for an interval, to be lost again. If we compute it in time, we may, in fifty years, have half a dozen reasonable hours.
    Ralph Waldo Emerson (1803–1882)

    The hippopotamus’s day
    Is passed in sleep; at night he hunts;
    God works in a mysterious way—
    The Church can sleep and feed at once.
    —T.S. (Thomas Stearns)
