Steps by Carlo Scarpa

The Butterfly's attractiveness derives not only from colours and symmetry, deeper motives contribute to it. We would not think them so beautiful if they did not fly, or if they flew straight and briskly like bees, or if they stung, or above all if they did not enact the pertubing mystery of metamorphosis; the latter assumes in our eyes the value of a badly decoded message, a symbol, a sign.

From a physical standpoint, a black hole is a marvelously simple object, far simpler then the earth or a human being... When a black hole first forms, its horizon may have a grotesque shape and may be wildly vibrating. Within a fraction of a second, however, the horizon should settle down into a unique smooth shape. If the hole is not rotating, its shape will be absolutely spherical. Rotation, however, will flatten it at the poles just as rotation slightly flattens the earth.
