In the early 1900’s, scientists learned that they had the ability to produce nuclear energy (Anderson 4). Though, throughout the early 1900’s how to produce this energy was still puzzling to most scientists. Leo Szilard, a Jewish man fleeing from Germany in 1933 figured out that colliding a neutron with a nucleus would start the chain reaction needed to produce massive amounts of energy. Then, this energy could be channeled into a weapon that could wipe out an entire city. Szilard was afraid that his new nuclear research might get into the wrong hands. Eventually, he turned to another German scientist that was known around the world, Albert Einstein. Einstein agreed that this research in the grasp of Germany could mean the end of days. Finally, they decided it was best to give it to a strong ally power, the United States (Anderson 12-17). This research continued throughout World War Two. After discovering how to get this reaction to work and bring the theory to life, the …show more content…
The help that was left in the city quickly ran out of supplies and MEDs, all exits out of the city were inaccessible. 40 percent of the city of the city was wiped out. Fires raged in the city for numerous days after the bombing. Buildings, hospitals, and school were scorched to the ground. A few hours after detonation (Hiroshima and Nagasaki Remembered), United States planes flew over the destroyed city and dropped three Leaflets demanding surrender (Sullivan 119-120). Japan soon realized the destruction that could be brought by the United States with this new found bomb. However, they did not surrender. Three days later ‘’Fat Boy,’’ a second atomic bomb was dropped on Nagasaki, another industrial city. With the leaders of Japan, no longer willing to see their country and people be destroyed any longer, they finally surrendered (Poolos 101-103). Although the two bombs were devastating, Hiroshima proved to be more effective than
In today’s society, many countries and even citizens of the United States question the U.S. government’s decision to get involved in nuclear warfare. These people deemed it unnecessary and stated that the U.S. is a hypocrite that preaches peace, but causes destruction and death. Before and during World War II the U.S. was presented with a difficult decision on whether or not to develop and use the atomic bomb. The U.S. decided to develop the atomic bomb based on the fear they had for the safety of the nation. In August 1939 nuclear physicists sent manuscripts to Albert Einstein in fear the Germany might use the new knowledge of fission on the uranium nucleus as way to construct weapons.
This chemistry book report is focus on a book called “Napoleon's buttons: How 17 molecules changed history” by Penny Le Couteur and Jay Burreson. The publisher of this book is Tarcher Putnam, the book was published in Canada on 2003 with 17 chapters (hey the number match the title of the book!) and a total of 378 pages. The genre of this book is nonfiction. “Napoleon's Buttons” contain a fascinating story of seventeen groups of molecules that have greatly changed the course of history and continuing affect the world we live in today. It also reveal the astonishing chemical connection among some unrelated events, for example: Chemistry caused New Amsterdamers to be renamed New Yorkers and one little accident of detonating cotton apron in a minor housekeeping mishap lead to the development of modern explosives and the founding of the movie industry.

Physicists found out that among the pieces of a split atom were newly produced neutrons. These might encounter other uranium nuclei, cause them to split, and start a chain reaction. If the chain reaction was limited to a moderate pace, a new source of energy could be the result. The chain reaction could release energy rapidly and with explosive force. Leo Szilard, Eugene Wigner, and Edward Teller, Hungarian-born physicists, were frightened by the possibility that Germany might produce an atomic bomb.
Nevertheless, Lincoln made use of this advantage by tapping and capitalizing on electric communications. This is considered as something remarkable because it is utilized without precedence and it was use in a time where war was waged in America during the Civil War.
At that time, the schedule was delayed for fifteen minutes. Bockscar carried the atomic bomb which was Fat Man. The top target was Kokura and Nagasaki was the second target for dropping the atomic bomb. The captain who operated Bockscar had orbited for forty-five minutes around Yakushima. Then he decided to go to Kokura. At 10:20 a.m., Bockscar was flying over Kokura; however, Kokura was covered by heavy clouds and smoke because on August 8 at night, B-29s had dropped the bombs at Yawata. The captain of Bockscar thought that dropping the atomic bomb was extremely difficult and it had a chance to fail. Also, Bockscar did not have enough fuel to keep flying. Then, Bockscar changed the target from Kokura to Nagasaki. At 11:02 a.m., the second atomic bomb was dropped at Nagasaki (Harder). From a height of 9600 meter, the atomic bomb was dropped and exploded at a height of 503 meter. The power of the atomic bomb was more than the first atomic bomb. However, the damage was less than Hiroshima because of the geographical features of Nagasaki. Nagasaki was surrounded by mountains, so the mountains blocked the heat rays, radiation, and blast ("Overview.") In short, the damage in Nagasaki was less than Hiroshima even Nagasaki was exploded by the atomic
After being taken by the Germans convinced others that they still had the lead in developing a fission weapon. It all started with the “Hungarian conspiracy” that had everyone convinced that the creation of a nuclear bomb was possible, but that the German government was already doing research in this field of study on such a weapon. To the rest of the world, the thought of Adolf Hitler might be the first to gain control of a weapon this destructive would be terrifying to the United States. Right, then they decided that the administration of President Franklin D. Roosevelt must be warned about the dangers and that the United States must begin its research department. As the planned gave way, Einstein was to write a letter to President Franklin D. Roosevelt about the possibilities and dangers of the atomic weapons, and later was taken to the president.
The effects of the atomic bomb might not have been the exact effects that the United States was looking for when they dropped Little Boy and Fat Man on Hiroshima and Nagasaki respectively (Grant, 1998). The original desire of the United States government when they dropped Little Boy and Fat Man on Hiroshima and Nagasaki was not, in fact, the one more commonly known: that the two nuclear devices dropped upon Hiroshima and Nagasaki were detonated with the intention of bringing an end to the war with Japan, but instead to intimidate the Soviet Union. The fact of Japan's imminent defeat, the undeniable truth that relations with Russia were deteriorating, and competition for the division of Europe prove this without question. Admittedly, dropping the atomic bomb was a major factor in Japan's decision to accept the terms laid out in the Potsdam agreement, otherwise known as unconditional surrender. The fact must be pointed out, however, that Japan had already been virtually defeated.
After Truman decided to bomb Japan, they had to plan it out. They first had to decide where to release the bomb. They ended up choosing Hiroshima, Japan and Nagasaki, Japan as their two locations. Hiroshima was a significant military city in the war. It confined two army headquarters and was Japan’s communication center (World War 2 Atomic Bomb 1). Hiroshima was also a huge industrial city and had not been bombed before so it would let Japan see the wrath of the United States (Koeller 1). The planning and actual event of the bombing went great. On August 6, 1945 at 8:15 in the morning the bomb was dropped. The bomb that landed in Hiroshima was called the “Little Boy” (World War 2 Atomic Bomb 2). The bomb ended up killing about 170,000 people. 70,000 people died the first day and 100,000 people died in the next few months due to the radioactivity of the bomb and burns fro...
“Little Boy” and “Fat Man”, the world’s first two nuclear bombs were dropped in two major cities in Japan: Hiroshima and Nagasaki on the 6th and 9th of August 1945. This “experiment” by the United States Government completely demolished the two cities, killing over 150,000 people instantly and nearly 50,000 people died from aftermath as well as radiation.
“Little Boy,” the bomb dropped on Hiroshima killed 70,000 people with an additional 66,000 injured (30-39). “Fat Man,” the bomb dropped on Nagasaki, also carried its “share of America’s duty” by killing 40,000 people and injuring another 25,000 (30-39). The bombs also killed an estimated 230,000 more people from the after effects of the two explosions (30). The two bombings had opened the world’s eyes to the destructive power that could be unleashed by man. The bombs had raised hell on earth for those few minutes and produced a tremendous amount of casualties.
Also, many messages between the United States and Japan declared that if the Japanese didn’t surrender, they would face ultimate annihilation (Atomic bomb). Consequently, when the Japanese refused to budge, the United States dropped two atomic bombs, the Little Boy and the Fat Man, on the cities of Hiroshima and Nagasaki. As a result, the Japanese people faced ultimate plight.
The capability for nuclear energy has always existed. However, not until December 2, 1942, at the University of Chicago, did nuclear energy surface. Enrico Fermi made that discovery by making a chain reaction in a pile of uranium. How a nuclear reaction works is that a neutron is “shot” through a gram of uranium, which creates fission. This causes a chain reaction, thus creating a nuclear reaction or nuclear energy. This was the first man-made nuclear reaction.
Military advisers warned Truman of the possible fatalities of thousands of American soldiers. If the war was to be efficiently reduced and the survival of numerous United States soldiers was to be saved, it was vital to produce a strong blow against the Japanese. The cities of Hiroshima and Nagasaki were virtually untouched by test bombings, but were specifically chosen as targets by military specialists. A B-29 plane – the “Enola Gay” controlled by Paul W. Tibbets – dropped a uranium atomic bomb (“Little Boy”) on Hiroshima on August 6, 1945. Within minutes, 60,000-70,000 people were killed; hence, half the city disappeared with 140,000 injured and several made homeless as a result of the blasting. Within the blast, thousands died instantly and 100,000 came in contact with radiation. With over 60,000 buildings ruined, the city was completely distressed. The B-29 bomber “Bockscar” – piloted by Sweeney – three days after Hiroshima, the plane changed from its original course (Kokura) to Nagasaki. The “Fat man” bomb exploded over the north factory district to attain the maximum blast outcome; hence, many buildings collapsed, electrical systems were cut, and a wave of secondary fires occurred
Hundreds of thousands of people lost their lives, and many were injured after the event took place which left the whole world appalled. During this event an American B-29 had gone through with the command to drop the nuke and cause massive destruction to Japan.Because of Pearl Harbor the United States decided to get revenge on Japan. The bombing on August 6, 1945 in Hiroshima and Nagasaki resulted in the collapse of the economy and a drastic impact on the people but helped with the formation and structure of
