Do wars drive technological advancement?

According to the late Edwin Star, war has no advantage at all. But how much of the technology we rely on today is beginning as military technology? If we are a peaceful species, is it possible to not develop technology like microwave oven or internet?

War throws great demands on national resources. These resources range from materials to military resources. Getting a war is expensive. War put a burden on the citizens of the country. As soldiers come to fight, the remaining people must work harder to keep the nation's infrastructure collapsing.

But war will also have a positive impact on economic and technological development. In general, warfare tends to accelerate technology development to adapt to instruments to deal with specific military needs. Later, these military tools may evolve into non-military devices.

A recent example is radar. At the beginning of the 20th century scientists from all over the world used radio antennas to detect distant objects, but in 1935 Sir Robert Watson-Watt produced the first practical radar I believe.

Radar has become an important tool for armies all over the world. In other words, recruitment of radars requires each country to adapt to a new war strategy. This also encouraged the United States to invest in research and development of new ways to confound the radar. Stealth Aircraft Technology

Civilian, radar plays a different role. A scientist named Percy L. Spencer made an interesting discovery near the magnetron - the magnetron is a device to move radar equipment. Spencer had a chocolate bar in his pocket. As Spencer approached the magnetron, the bar began to melt. This pushed Spencer 's curiosity and he began to study what happened. This led to the invention of a microwave oven

"Technology always meets the needs of a certain period of time." During the First World War, technology has improved. World War II began shortly after the war. This opens the wave of new technology and became the main focus of war. Within this wave, more reliable weapons, means of transportation and equipment were created. Many of the most important weapons and progress in the Second World War have previously appeared in the First World War. These advances can be seen primarily in the land. New technology also appears in the sky. The ocean is also a wonderful area for improvement. The technology soon became very powerful, "Reversibly changed ways of war" (World War II 7). During World War II, there were many technological advances on land. With the emergence of their demand weapons, equipment, transportation, chemicals and other inventions were developed. Most of the weapons used are from the First World War, so they are outdated.

Advances in technology and science have contributed to the most blood and bloodlike wars in the history of human existence. Advances in these new technologies have revolutionized the way people think about war. War is no longer a battle of opposition forces in coordinated battle. War has evolved into a tactical game where bigger, stronger, and smarter toys play better. This invites intense competition, the two sides are trying to make smarter machines and better weapons ... Although it can not be avoided in war, we can reduce the number of victims. Throughout history, one of the greatest destructive behaviors was that the United States launched the atomic bomb in Hiroshima and Japan's Nagasaki. World War II began in 1939 and continued until 1945. At the time, German dictator Adolf Hitler took over Poland, received assistance from France and the United Kingdom and warned not to do so. France and the UK subsequently declared war in Germany and Germany
