Introduction
In August 1945, two atomic bombs ‘Little Boy’ and ‘Fat Man’ were dropped in Hiroshima and Nagasaki in Japan, and over 200,000 people were killed immediately (ctbot.org, 2013). The principle of atomic bomb is based on the nuclear fission, which is the process that generates huge amount of energy. The modern development of nuclear technology enables fission weapons to be more powerful with a smaller size, and much easier to deliver than earlier types. However, the nuclear radiation produced by fission weapons are highly radioactive and long-lived. This would negative impact humans and the environment. Furthermore, the purposes of the uses of fission weapons in different countries will be considered and discussed.
Physics of Fission
Fission weapon uses the process of nuclear fission to produce large amount of energy. Uranium-235 is a valuable isotope found naturally on the earth (consists of 0.7% U-235) because it can serve as a primary fuel for a weapon. Fission is induced by the capture of a neutron. When a U-235 atom absorbs a neutron, it splits into two lighter nuclei and the process is accompanied with the emission of several neutrons because the heavy nucleus has a higher neutron to proton ratio than the two fragments. There is also the accompanying emission of gamma rays. The released energy is given by where is the mass lost in the reaction and is the speed of light (universal constant ). This energy is in the form of kinetic energy of the product
When a uranium nucleus splits, energy is released (as steam). This steam turns generators and creates electric energy. One pro is that nuclear fission does not release as many pollutants as fossil fuels. Two cons are that it nuclear waste is hard to dispose of and also can be harmful for humans.
In November of 1861, the Confederate president, Jefferson Davis, sent two Confederate envoys, James Mason and John Slidell on a mission. They were sailing to England and France, on a British ship named Trent. They were traveling to Great Britain to get support for the southern states in the Civil War. At that time, the British had been neutral in the Civil War issues in the United States. The crisis started when a union captain of the USS San Jacinto, named Charles Wilkes, captured and arrested Mason and Slidell. These prisoners were sent to a prison called Fort Warren. This made the British government angry because it was a violation of international law to board and search a ship without permission. The British sent a messages to
In this paper, we will discuss the pros and cons of nuclear bombs during world war II. But before we can discuss this we need to know what a nuclear weapon is, according to Thomas B. Cochran it is a "device designed to release energy in an explosive manner as a result of nuclear fission, nuclear fusion, or a combination of the two processes". Weapons were very helpful for the army but not for civilians because many civilians were injured and even killed. The Hiroshima and Nagasaki bombings are great examples of weapons injuring and/or killing civilians However, this successfully made japan back away from the fight so it goes both ways. There are many controversies in
If nuclear weapons are used in war sustainable life on this planet will be ended. Nuclear Weapons have only been used a few times in the history of this earth. The few times nuclear weapons were used the amount of damaged they caused was devastating. The first country to use nuclear weapons was the United States during World War II. On August 6, 1945 an atomic bomb nicknamed “Little Boy” was dropped on Hiroshima killing between 90,000 and 166,000. Then on August 6th, 1945 the second atomic bomb nicknamed “Fat Man” was dropped on Nagasaki killing 60,000 – 80,000 people. These statistics show how devastating nuclear weapons were when they were used and how they can be if they are used again. This paper will examine the Dangerous effects of
The first use of nuclear weaponry in warfare occurred on the morning of August 6, 1945 when the United States dropped the atomic bomb known as “Little Boy” on Hiroshima, Japan. The result was devastating, demonstrating the true power of nuclear warfare. Since the incident, the world has been left fearing the possible calamity of another nuclear war. Joseph Siracusa’s Nuclear Weapons: A Very Short Introduction explains aspects of nuclear weaponry from simply what a nuclear weapon is, to the growing fear from nuclear warfare advancements in an age of terrorism. The book furthered my education on nuclear weapons and the effect they place on society, physically and mentally.
With the start of World War II the race for the first atomic bomb started. With Germany under Hitler’s reign, the Nazis began separating uranium to form the first atomic bomb to control the world. The push for the United States build the first atomic bomb began with this knowledge. With the help of several scientists the United States succeeded in building the atomic bomb first. Two atomic bombs were used; a uranium bomb on Hiroshima and a plutonium bomb on Nagasaki. Along with the many deaths were six stages of A-bomb illness which includes acute stages, atomic bomb trauma, A-bomb radiation illness, radiation blood injury at lethal dosage, blood injuries, and secondary radiation illness. Seven unhealed scars were also an effect of the atomic bombs that includes keloids, A-bomb cataracts, leukemia, cancers, chromosome changes, exposure in utero and microcephaly, and genetic surveys. Regulations and guidance were set in place soon after the bombings to protect the people of the world based on the information that was gathered and it has changed over the years based on the new information that was learned. With the use of the atomic bombs in World War II, a lot of pain and suffering was caused, but a great deal of information was learned to help protect future generations from radiation.
“I have to bring to your notice a terrifying reality: with the development of nuclear weapons Man has acquired, for the first time in history, the technical means to destroy the whole of civilization in a single act.”- Joseph Rotblat. After the United States dropped an atomic bomb on the Japanese cities of Hiroshima and Nagasaki on August 6 and 9, forcing Japan to surrender on the 14, people finally got to see the pure and utter destruction that a nuclear bomb had the potential of. Seeing this power, the United States and the USSR fought for supremacy in nuclear warfare in a competition called the Arms Race. Nobody, however, really understood how much a nuclear detonation could affect a society not only physically, but socially, politically and medically as well.
As seen in World War II, the nuclear weapon engenders the havoc of humankind. Prior to its usage in wars, many scientists test the bomb on numerous places on earth, creating damage and radiation around these testing sites. Furthermore, death is the core outcome that arises from the usage of nuclear weapons. Sooner or later, the abuse of technology will harm the human race
An atomic or nuclear bomb is a bomb that causes destruction using the power from the rapid release of nuclear energy by fission of an atomic nuclei, causing damage through heat, blast, and radioactivity. Uranium and plutonium are the most popular ingredients in an atomic bomb. If an A-bomb is dropped, death is highly likely and radiation poisoning is almost certain if one is caught within a radius of 0-3 kilometers from a 1 megaton airburst. The 50% chance of death from the blast extends out to about 8 kilometers. The atomic bomb was only used twice to kill human beings: it was dropped on the Japanese people in Hiroshima and Nagasaki in 1945. On August 6th, 1945 the United States dropped the first bomb on the city of Hiroshima. This bomb was known as “little boy”. The Second Bomb dropped on Nagasaki, was nicknamed “Fat Man”. When the “Fat Man” was dropped and exploded with a blast yield equivalent to 21 kilotons of TNT at an altitude of 1,650 feet. A total of about 199,000 people died in the bombings of both Hiroshima and Nagasaki.

In this paper, it will be discussed why the Atomic Bomb is the biggest method of destruction known to man. The paper will be discussing the results of the Atomic Bombs, along with the effects years after the initial explosion. People always wonder how many people actually died in the two Atomic Bombs which were dropped in Japan. This question will be answered, along with the method that citizens were actually killed by the bomb. Besides the initial blast winds that an Atomic Bomb gives off, people may be killed by several other things including heat rays, radiation and the implosion of their home.
The event that I chose to discuss is the dropping of the atomic bomb on Hiroshima and Nagasaki. I believe that this event is worth studying because it was the first and only time that an atomic bomb had been used in war. The significance of this event can be seen from different sides and affected not only future policies, national security, the future of energy development, and health related issues. This event is said to have ended World War II, and at the same time started the cold war. The bombs were said to have ultimately killed over 700,000 Japanese people (Nash, 2014). New medical and mental illnesses occurring due to dropping the bomb and radiation, and also starting new threats of nuclear attack throughout the world and the continued threat of creating and use of the atomic bombs. With the use of the atomic bomb, the world considered countries that had the power of the atomic bomb to be a superpower and countries like Russia wouldn’t let the U.S. be the only ones who had this power. Russia would build an atomic bomb and the threat of war was now considered to be fought with nuclear annihilation.
A nuclear weapon is a device with explosive energy, most of all of which derives from fission or a combination of fission and fusion processes. Nuclear fission produces energy by splitting the nucleus of an atom, usually highly enriched uranium or plutonium, into two or more parts by bombarding it with neutrons. Each nucleus that is split releases energy as well as additional neutrons that bombard nearby nuclei and sustain a chain reaction. Fission bombs provide the catalyst for more complex thermonuclear explosions. In such weapons a fission explosion
On August 6 and 9th, 1945, the world’s first atomic bombs were dropped in a race to end World War II. The first nuclear bomb, ‘Little Boy’, dropped over Hiroshima, Japan wiped out ninety percent of the city and immediately killed thousands. Three days later, a second atomic bomb dropped on this time over the city of Nagasaki. The bombs were created by scientists who worked in secret for years on "The Manhattan Project" to perfect weapons that would bring an end to the long and traumatizing fight of World War II. The use of the atomic bomb at the end of World War II has had global consequences that are still being dealt with today.
As a result of the immensely diverse nature of the phenomena it intends to understand, the study of religion requires a multitude of analytic methods. Consequently, these methods may be categorized as either being grounded in empirical analysis of biological, psychological, or physiological data - producing a perspective which is exclusively characterized as outsider. Thus, according to this definition, Sigmund Freud’s application of his Oedipus Complex theory is a near perfect example of an explanatory Classical Psychological Approach to religion, claiming that individuals turn to an “omnipotent, benevolent father figure” (Kanaris) alleviate the sexual anxiety which develops when children begin viewing their parent of the opposite sex as an object of desire. In this sense, Freud negatively reduces the phenomena to an infantile form of escapism from life’s hardships. Furthermore, Freud alleges that this immature psychological response will eventually give way to “the more excellent procedure of science.”(Kanaris) This conclusion makes evident the foremost flaw of conduction studies which are purely explanatory: they tend to be
