A whip begins with a wider diameter and tapers to a much smaller diameter. The whipcracker imparts energy to the beginning of the whip with his or her arm. The crack of a whip comes from a loop that is made by the motions of the whipcracker. As the energy in the loop passes through the tapering whip the energy is amplified exponentially. The loop travels down the whip until, at last, some part of the end of the whip reaches the sound barrier and creates the sonic boom.
(the last day, the last hour) i was in the woods for nearly three months and i dropped my camera in the middle of Canal Baker. a splash and then a dark object only visible for a moment in the cloudy wine blue water… . . about a week later i bought a new camera duty free on the way to Buenos Aires and i have been documenting my travels in the long two weeks since.
PERO YA NO HAY TIEMPO
