The atomic bomb and nuclear bombs are powerful weapons that use nuclear reactions as their source of explosive energy. Scientists first developed nuclear weapons technology during World War II. Atomic bombs have been used only twice in war—both times by the United States against Japan at the end of World War II, in Hiroshima and Nagasaki. A period of nuclear proliferation followed that war, and during the Cold War, the United States and the Soviet Union vied for supremacy in a global nuclear arms race. Nuclear Bombs and Hydrogen Bombs A discovery by nuclear physicists in a laboratory in Berlin, Germany, in 1938 made the first atomic bomb possible, after Otto Hahn, Lise Meitner and Fritz Strassman discovered nuclear fission. In nuclear fission, the nucleus of an atom of radioactive material splits into two or more smaller nuclei, which causes a sudden, powerful release of energy. The discovery of nuclear fission opened up the possibility of nuclear technologies, including weapons. Atomic bombs get their energy from fission reactions. Thermonuclear weapons, or hydrogen bombs, rely on a combination of nuclear fission and nuclear fusion. Nuclear fusion is another type of reaction in which two lighter atoms combine to release energy. Manhattan Project On December 28, 1942, President The Manhattan Project was the code name for the American-led effort to develop a functional atomic bomb during Who Invented the Atomic Bomb? Much of the work in the Manhattan Project was performed i...

Nagasaki Day is observed on 9 August. On this day US dropped an atomic bomb on the Nagasaki city of Japan in 1945 during World War II. The first bomb was dropped on the city of Hiroshima and the second was dropped on Nagasaki on 9 August which killed around 74,000 people or more. After six days of the Nagasaki bombing, the Japanese Emperor Gyokuon-Hoso speech was broadcast to the nation, addressing the surrender. The devastation caused due to the bombing led Japan to surrender in World War II. Reason behind dropping an atomic bomb on Japan two cities According to the sources reason behind dropping the atomic bomb on Japan two cities and according to the US President Truman is the military. Dropping the bomb would end the war quickly and effectively with the least amount of casualties on the U.S side. He also wants to justify the expenses of the Manhattan Project where the bomb was created. Bombing impressed the Soviet Union and created a response to Pearl Harbour. No doubt bombing forced Japan to surrender. About Atomic Bomb The bomb was uranium bomb. When it was dropped on Hiroshima on 6 August 1945, it had an explosive yield equal to 15,000 tonnes of TNT. While a slightly larger plutonium bomb exploded over Nagasaki just two days later on 9 August levelled 6.7 km square of the city and killed around 74,000 people by the end of 1945. The temperature of the ground reached 4,000 degrees Celsius and radioactive rain poured down. Most of the physicians and nurses in Nagasaki ...

First came a flash. Thirteen-year-old Setsuko Nakamura felt as if she were drifting skyward. And then darkness. Seventy-four years later Setsuko still remembers the moment of detonation after the U.S. dropped the atomic bomb on Hiroshima, the first of two exploded over the island nation, a deployment that proved so horrendous the weapons have never been used since. “That very morning I was at the military headquarters, not at the school,” she told a rapt audience at Harvard Law School on Tuesday as part of the University’s Setsuko, who now uses her married last name Thurlow, and about 30 other girls were assigned to help the army decode top-secret messages. They were about a mile from ground zero and on the building’s second floor. “Sharp at 8 o’clock the assembly started,” she said. “Maj. Yanai was giving a pep talk: ‘This is the day you prove your patriotism to the emperor. Do your best,’ and so on. We said, ‘Yes, sir! We’ll do our best.’ Then at that second I saw the blinding blueish-white flash in the window, and I had a sensation of floating up in the air.” Then she lost consciousness. As a living witness to the devastation and human suffering the use of nuclear weapons brings, Thurlow has been telling this story for decades now. Often she brings her listeners to tears, as she did this day. “I speak because I feel it is my responsibility as someone who has intimate knowledge of what these horrific things can do to human beings,” Thurlow said. “I consider it my moral r...

On August 31, 1946, the editors of The New Yorker announced that the most recent edition “will be devoted entirely to just one article on the almost complete obliteration of a city by one atomic bomb.” Though The New Yorker believed that “few of us have yet comprehended the all but incredible destructive power of this weapon, and that everyone might well take time to consider the terrible implications of its use.” Theirs was a weighty introduction to wartime reporter John Hersey’s four-chapter account of the wreckage of the atomic bomb, but such a warning was necessary for the stories of human suffering The New Yorker’s readers would be exposed to. Hersey was certainly not the first journalist to report on the aftermath of the bombs. Stories and newsreels provided details of the attacks: the numbers wounded and dead, the staggering estimated costs—numerically and culturally—of property lost, and some of the visual horrors. But Hersey’s account focused on the human toll of the bombs and the individual stories of six survivors of the nuclear attack on Hiroshima rather than statistics. Hersey was both a respected reporter and a gifted novelist, two occupations that provided him with the skills and compassion necessary to write his extensive essay on Hiroshima. Born in Tientsin, China in 1914 to missionary parents, Hersey later returned to the states and graduated from Yale University in 1936. Shortly after, he began a career as a foreign correspondent for Time and Life magazi...
