For most people, it is an obvious answer for that statement, because new technologies have become part of our life. However, in a short story, called “The Weapon”, Frederic Brown tells us about a story of a visitor Mr. Niemand tried to convince Dr. Graham who was working on a new weapon to stop his experiment. But Dr. Graham refused to follow what did Mr. Niemand said. Finally, that “madman” gives a loaded revolver to Dr. Graham’s son-Harry a boy with a mental handicap as a gift to show that new technology is often a double-edged sword, which means it doesn’t always have the positive effects for people; sometimes people can’t even handle the new technology.
World War II had one of the highest death rates in human history, but it also was known as a time that led to the development of new scientific techniques. According to statistics, there were more than seventy million innocent people died in that six years period. Atomic bomb first time appeared with the life and blood of our brethren. an American bomber dropped the world’s first deployed atomic bomb over the Japanese city of Hiroshima. The explosion wiped out 90 percent of the city and immediately killed 80,000 people; three days later, a second bomber dropped another A-bomb on Nagasaki, killing an estimated 40,000 people. Tens of thousands more would later die of radiation exposure. On the other hand, the arms race seemed like to be the only theme of the Cold War, which endangered international relations by both USA and Soviet sides.
The afraid of the war turned into the hippie movement, the most famous sign represents the peace-V sign.  In the 1950s the “peace sign”, as it is known today, was designed by Gerald Holtom as the logo for the British Campaign for Nuclear Disarmament, a group at the forefront of the peace movement in the UK, and adopted by anti-war and counterculture activists in the US and elsewhere. V-sign was the sign that represented the victory for WWII. Furthermore, the V-sign has a long history representing the victory since Hundred Years’ War, this origin legend dictates that the English and Welsh archers who were captured by the French had their index and middle fingers cut off so that they could no longer operate their longbows, and that the V Sign was used by uncaptured and victorious archers in a display of defiance against the enemy. But that origin hasn’t got proved yet.
