Pen Versus the Sword (Peace Versus Violence) in World...

The pen is mightier than the sword The pen influences your mind peacefully. Weapons do not. They tend to violate every path of human kind. The pen influences more people than the sword and has more impact on their lives. The power of the sword is negative destruction of life, and the sword has only caused problems during its reign of power. Early man relied on their muscle power. In fight the for existence, it was survival of the fittest. Gradually man became civilized and progressed in society. The fate of nations was shaped by wars and gradually man realized that weapons cannot solve problems. â€Å"Weapons could kill a man but cannot bring change to his mind† (Goldsmith, 46). The French citizens made a big mistake by†¦show more content†¦Although he made powerful enemies, Voltaire never stopped fighting for tolerance, reason, freedom, freedom of religion, beliefs, freedom of speech. He used his quill pen as if it were a deadly weapon in a thinkers war against humanities worst enemies-intolerance, pr ejudice and superstation .he summed up his staunch defense of liberty in one of his most famous quote â€Å"I do not agree with a word you say but will defend to the death your right to say it† (Marvin, par-1). â€Å"And so philosophers bought a huge impact on the French revolution. â€Å"No clash of arms could achieve what great man through their writing has achieved† (Abbey, par-4).

Essay On Nuclear Submarines Example For Students

Essay On Nuclear Submarines The Evolution of the Sumarine Due to WarThe submarine is an extreamly useful tactical tool. Bred through war, the submarine is one of the most advanced covert weapons technologies today. The submarine is a ship designed and built to travel under water. A true submarine spends the majority of time under water and is capable of staying under water indefinaltely(Rush 140). The only true submarine today is the nuclear sub. The first true submarine is the U.S.S nautilus(Rush 141). There are two main types of war affiliated submarines, attack submarines and ballistic missile submarines. The attack submarine is designed to seek and destroy enemy submarines and surface ships. The much larger ballistic missile submarine is designed to carry multiple warheads to attack enemy cities and military facilities ashore(Polmar 748). The submarine origionated over 2,000 years ago when Alexander the great went below the Mediteranian Sea in a glass barrel(Wyckoff 13). Submarines were toyed with by scientists through the years but not many uses were found for the concept of a submersable until the revolutionary war. The first attack submarine was the Turtle, designed by a student at Yale university by the name of David Bushnell, its purpose was to sink a British war ship in New York Harbor(Polmar 750). Its mission was a failure but none the less was the first attempt to sink a ship with a submersable(Polmar 750). The first success was made durring the Civil War(Polmar 750). The Confederate sub Hunley rammed the Union ship Housatonic in Charleston Harbor, and both the Hunley and the Housatonic sank(Polmar 750). The Hunleys weapon consisted of an explosive at the end of a long pole wich was to be set off when in close enough proximity to the ship it was to attack(Polmar 750). The submarine has advanced dramaticly due to war. The first major advancement in submarine technology is the invention of a gasoline and batery powered submarine by John P. Holland(Polmar 750). This ship was bought by the US Navy in 1900 and named the U.S.S Holland(Polmar 750). The U.S.S Holland was capable of speeds of 6 knots submerged(Polmar 750). The gasoline and battery powered combination allowed for submarines to run on gasoline while surfaced, and by battery power when submerged and combustion was no longer possable without wasting valuable oxogen within the submarine. The next leap in the technological development of the submarine was the periscope developed by Simon Lake in 1902(Polmar 750). The periscope allowed a submarine to site distant targets by use of a magnifying lense. A few years later the diesel and battery powered submarine was developed in Great Brittan(Polmar 751). The diesel submarine was cheeper to operate, more powerful, and produced less dangerous fumes th an gasoline powered submarines. The majority of submarines were diesel until the next revolution in submarine technology, the nuclear powered submarine. Although submarines were used extensivey durring WWI and WWII, the greatest advances were made to submarine technology,as well as other technologies due to the submarine, during WWII. The submarine was used extensively by the german military durring both WWI and WWII, and became a major threat to enemy millitary, as well as merchant, ships. This increased the rate at wich technology was developed both to aid and to destroy the submarine. An example of an advancement in technology, related to the submarine, is that of a device employed by the German military, for German submarines, or U-boats (Unterseebooten), is the snorkel(Botting 161). The idea of a snorkel had been around for quite some time however was not well devoloped until the Germans took intrest(Botting 161). The snorkel allowed for submarines to run their engines while submerged. Until the germans modified it, the snorkel was little more than a hose kept out of the water by a float(Botting 161). The germans perfected the s norkel by using a rigid telocopic pipe rather than a flexable hose and by using a float on the inlet so that if the U-Boat dipped too far under water, it would close the inlet preventing the water form entering the combustion engine(Botting 161). Two technologies wich were developed because of the threat by German U-boats are radar, allready in use by the allies to search for and track airplanes, and sonar, a new technology. To counter allied radar the Germans placed a rubber mesh acrost their snorkels to make detection more difficult(Rush 50). .u55b34566df9bdfb39612d3e314147f93 , .u55b34566df9bdfb39612d3e314147f93 .postImageUrl , .u55b34566df9bdfb39612d3e314147f93 .centered-text-area { min-height: 80px; position: relative; } .u55b34566df9bdfb39612d3e314147f93 , .u55b34566df9bdfb39612d3e314147f93:hover , .u55b34566df9bdfb39612d3e314147f93:visited , .u55b34566df9bdfb39612d3e314147f93:active { border:0!important; } .u55b34566df9bdfb39612d3e314147f93 .clearfix:after { content: ""; display: table; clear: both; } .u55b34566df9bdfb39612d3e314147f93 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u55b34566df9bdfb39612d3e314147f93:active , .u55b34566df9bdfb39612d3e314147f93:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u55b34566df9bdfb39612d3e314147f93 .centered-text-area { width: 100%; position: relative ; } .u55b34566df9bdfb39612d3e314147f93 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u55b34566df9bdfb39612d3e314147f93 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u55b34566df9bdfb39612d3e314147f93 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u55b34566df9bdfb39612d3e314147f93:hover .ctaButton { background-color: #34495E!important; } .u55b34566df9bdfb39612d3e314147f93 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u55b34566df9bdfb39612d3e314147f93 .u55b34566df9bdfb39612d3e314147f93-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u55b34566df9bdfb39612d3e314147f93:after { content: ""; display: block; clear: both; } READ: Path To Power EssayDue to submarines, some of the most incredable advanses in millitarty technology have been made.
