Thus the “fire trees” and “silver flowers” were born. Later on in the year 1161, when the Chinese were suffering invasion from the Chin Tatars from the north some historical documents state that they successfully used explosives to defeat their attackers. This seems to be definite proof of a knowledge of gunpowder among the Chinese at this period. However there has been considerable argument as to whether these references to explosives indicate that the Chinese knew about the use of a cannon and also i... ... middle of paper ... ... large iron pots, and as it was heated, scum consisting of common salt, rose to the top and was skimmed off. After the maximum amount of salt had been removed, a quantity of vinegar was added to the mixture and then the mixture was boiled for a further period until it was concentrated enough to crystallize.
Napalm was Introduced during World war II. Napalm would be used on the soldiers in entrenched positions. This greatly reduced the morale and causing extreme mayhem. Phosphorous grenades were also Used, causing major skin burns after explosion. The use of chemical weapons has become Harder to guard against, causing more casualties, and becoming harder to detect and defend Against.
Gunpowder was invented long before the Europeans were introduced to it. Gunpowder was invented by the Chinese in the ninth century . They were actually trying to make an elixir of eternal life, but ended up making one of the most important artifacts of warfare . The Chinese did not originally use gunpowder in weapons, but in fireworks instead. The smoke that combusted gunpowder makes is very thick and can block the colors of the fireworks from being shown, so they had to have different ratios of gunpowder .
Made bigger and powerful cannons. With more elements of the periodic table. Later in the years about 1900’s. The world wars came about. Hydrogen cyanide HCN, prussic acid, is a chemical compound in the form of a powerfully poisonous, volatile colorless liquid with the odor of bitter almonds.
Second, Britain had a surplus of Opium, a drug grown in India, and it needed vast numbers of people to purchase it. China traded peacefully although reluctantly with Britain, until the government noticed the negative effects of the drug on its people. The opium trade was then outlawed promptly by the Chinese government. The substance, however, was still smuggled into the country. The Chinese government confronted the British regarding the smuggling and this sparked the Opium War (1899-1902).
One of the most important inventions of all time was the invention of gunpowder. “Imagine their enemy's surprise when the Chinese first demonstrated their newest invention in the eighth century AD. Chinese scientists discovered that an explosive mixture could be produced by combining sulfur, charcoal, and saltpeter (potassium nitrate). The military applications were clear. New weapons were rapidly developed, including rockets and others that were launched from a bamboo tube” (Franklin Institute).
The effects of these gases were ghastly. Chlorine was the most deadly as "within seconds of inhaling its vapor, it destroys the victim's respiratory organs, bringing on choking attacks" (Duffy). Phosgene had similar effects, except the fact that the effects started kicking in after 48 hours of inhalation. In September 1917, the Germans introduced the mustard gas or Yperite which was contained in artillery shells against the Russians at Riga. Those exposed t... ... middle of paper ... ...eaponry and sophisticated machines, this total could have been reduce by nearly half and showed how destructive these weapons were.
Medieval Battle Tactics Medieval tactics were essential for an attack or siege of a castle. Many tactics and strategies helped develop much-improved version of an attacking artifact, like weapons and sieging machinery. The knights of Medieval England which were the cavalry, improved as the years went by, but never actually had any tactics or strategies. The usual knight would just go out there and fight. The knights were the counter offensive against a small siege, but they were ineffective against a large siege of a castle.
History of Fireworks The birthplace of fireworks is generally recognized as China, with the first explosive mixture found being black powder, during the Sung dynasty ( 960-1279 ). It is said that a cook in ancient china found that a mixture of sulfur, saltpeter, and charcoal was very flammable and would explode if enclosed in a small space. The first application of this technology was for entertainment. The Chinese are still the leader in the production of fireworks. Once the recipe for black powder was perfected, they found that it was easily used as rocket fuel, and they made hand carved wooden rockets in the shape of a dragon, in the sixth century.
All you have to buy is the ink and the material additives and the printer will do the rest. Major 3D printing companies like Stratasys have a great deal of success with their multiple lines of 3D printer, each catering to different sectors of consumer goods. Stratasys has three major line of 3D printer as follows: the Idea series, Design series and the Production series. The technology here is heralded as a designer’s dream tool as it brings ideas to life and the best thing is, these printers are available to everyone from individual designers to small groups. Let’s say, for instance, a toy designer is going to use a printer from the Idea series to prototype a design for a new toy that is slated ... ... middle of paper ... ...ss, child safety, time efficiency and a range of colors for unique designs.
