by Advancements in big science and technology not only changed how wars were fought but also gave a large advantage to those countries with the greatest achievements in science and technology. During the wars of the 20th Century those participating in the workforce and making the advancements in science and technology also changed drastically. Since many men went to fight, women joined the workforce now participating in advancing science and technology. Also participating in the workforce were European immigrants. For example, Einstein came to the USA from Germany before World War II and stayed, making some of the most important scientific discoveries which changed the war.
In the first world war there were many technological discoveries that helped change the way war worked by expanding communication. The development of the telegraph and telephone allowed allies to communicate quicker and from farther away than ever before, giving a huge advantage in strategizing. Although there were also much more destructive developments as well such as tanks, aircrafts for bombing, and machine guns. These machines were extremely beneficial to those who had them, but they also had negative side effects such as how easy it was to kill an enemy. These along with developments in science such as chlorine and mustard gas caused World War I to have over 16 million dead.
People were shocked by the number of people dead from World War I, but due to the developments in science and technology before and during World War II over four times more people died, many of which were innocent. With new developments in technology that allowed for mass destruction the way wars were fought changed. The atom bomb, arguably one of the deadliest weapons, was used during World War II. The large blast radius of this bomb destroyed not only soldiers but civilians around them as well. Also, now less people could cause more destruction. So, less soldiers had to be in the line of fire if they were dropping the bomb causing little risk to these soldiers dropping the bomb. Whatever country was most advanced in nuclear science held the most power.
Although there were many advancements in science and technology that were made for destruction, there were also some made for healing. Some of these developments consist of a tetanus antitoxin and debridement, or the removal of dead or infected skin. This was able to lower the mortality rate during wars, but not enough to compensate for the destructive machinery used.
Science and technology were extremely important in deciding who won the wars of the 20th century. Those with the deadliest developments were able to cause the most destruction during these wars. Although there were many incredible discoveries during this time most did more harm than good.
