(NYT19) NEW YORK -- July 3, 2002 -- CIR-FIREWORKS-2 -- Since the discovery of black powder more than 10 centuries ago, fireworks displays have been a mix of art and science. Knowledge of burn rates and ballistics has long been used to create choreographed explosions of stars, flowers and other patterns in the sky. But these days, computers have been added to the mix. Where fireworks displays of old were ignited by using flaming torches, today's displays are fired electrically from a safe distance. A worker loads fireworks shells into mortars aboard barges near Staten Island, N.Y. for Macy's July 4th fireworks extravaganza. With wires are electric matches that will be used to ignite black-powder charges in each shell for launching. (Ruby Washington/The New York Times)
