John Dalton was an English chemist‚ physicist‚ and meteorologist. Dalton was born in 1766. He is best known for his work in color blindness‚ and of course‚ his Atomic Theory. His theory gave us an idea about what the universe is really made up of‚ and he paved the way for many more important scientific discoveries after he died in 1844. His theory was simple: He stated that all matter is made of atoms. He based his theory on two laws: the law of conservation of mass and the law of constant composition

Debate Intro The pictures in front of you are the gruesome results of the utter destruction after the atomic bombs were dropped on both Japanese cities. Almost half a million victims; equivalent to 13‚000 tons of TNT; a 1.6 mile radius of destruction/bomb (within that radius‚ people were disintegrated‚ leaving shadows where they stood). Housewives and children were incinerated instantly‚ their internal organs boiled and their bones charred into brittle charcoal. 65% of the casualties were nine

On August 9th‚ 1945‚ the second Atomic Bomb was dropped on Nagasaki‚ and only three days earlier the first was seen in Hiroshima. These were two of the numerous events that propelled the most powerful combatants in history‚ the United States and Soviet Union‚ into the dangerous arms race we know as the Cold War. Many ask‚ “Was it necessary?” This is a controversial topic‚ asking whether or not the massacre of hundreds of thousands of Japanese civilians was worth saving a much smaller number of military

In 1945‚ when the atomic bomb was dropped in Japan I felt that it was not justified. Even though it saved thousands of American lives it was at the cost of others lives. The United States could have gave the Japanese a warning before dropping not one‚ but two bombs on them. However‚ the Japanese did not surrender until after the second bomb I think a warning would have made the bombing “justified.” To begin with‚ even though the United States and Japan were at war and were protected their own citizens

On May 7‚ 1945 Germany surrenders‚ and as Germany falls Hitler committed suicide thus ending the war in Europe. Several months later and after many American deaths President Truman decides to drop atomic bombs on Japan. According to Joel Wooton the first bomb known as “little boy” was dropped August 6‚ 1945 on Hiroshima‚ Japan. “Hiroshima‚ Japan was chosen to be bombed because it was the only city out of the 7 they had saved to bomb that one wasn’t under a lot of cloud cover.” (Wooton) They dropped
