It is well known that the Chinese invented gunpowder (a combination of sulfur, charcoal, and saltpeter), but it is not true that the Chinese were happy to use gunpowder for fireworks and never used it in war. They had incendiaries and primitive guns. The gun was originally viewed as the weapon of cowards. That anyone could use a gun, and that the results of such use were distant and consisted generally of random havoc rather than, say, a well-placed slice from a sword, took some of the valor out of fighting. By the sixteenth century, cannons had developed into forms that would still be used in the American Civil War. There was little scientific input into making either gunpowder or guns; it was, rather, the work of craftsmen who were the earliest engineers. The craftsmen had to put up with an inherently dangerous arena. Not only were accidental explosions common, but barrels inevitably exploded. Gunpowder burns at hundreds of degrees hotter than the melting point of iron, and every shot eroded the barrel.
There is a good deal of military history here, naturally, and lots about the effects of gunpowder or lack thereof on such wars as the American Revolution or the Civil War. Gunpowder had other effects, societal ones, changing the importance of class. Kelly writes that since it enabled commoners to hold in their hands a new form of lethal power, gunpowder was "...among the elements that fertilized the long slow growth of feelings of rights and entitlements that would blossom into democracy." It also inspired physics. Studying the trajectory of cannonballs, Galileo was able to overthrow the classical physical theories of Aristotle. Newton, building on this, performed the famous thought experiment of firing a cannonball harder and harder from a mountain, hard enough eventually that the ball would only fall in maintaining an orbit around the earth; from there it was but a jump to celestial motions. Eventually, gunpowder was surpassed by better chemicals; investigations into nitroglycerin and dynamite in the 19th century brought better-burning, safer means of shooting guns and cannons. "Black powder" is now the name given to the gunpowder which is the subject of this interesting and wide-ranging history. It is still manufactured, much going to the army of hobbyists and historical reenactors. The greatest market, however, merely shows that things have not changed too much. We take the same delight in fireworks as the Chinese did a thousand years ago, and use the same gunpowder for the charge.
