Fizzle (nuclear Explosion)
A fizzle occurs when the detonation of a device for creating a nuclear explosion (such as a nuclear weapon) grossly fails to meet its expected yield. The bombs still detonate, but the detonation is much weaker than anticipated. The cause(s) for the failure might be linked to improper design, poor construction, or lack of expertise.Staff Writer.NBC Weapons: North Korean Fizzle Bomb" ''Strategy Page.''

Boosted Fission Weapon
A boosted fission weapon usually refers to a type of nuclear bomb that uses a small amount of fusion fuel to increase the rate, and thus yield, of a fission reaction. The fast fusion neutrons released by the fusion reactions add to the fast neutrons released due to fission, allowing for more neutron-induced fission reactions to take place. The rate of fission is thereby greatly increased such that much more of the fissile material is able to undergo fission before the core explosively disassembles. The fusion process itself adds only a small amount of energy to the process, perhaps 1%. The fuel is commonly a 50-50 deuterium-tritium gas mixture, although lithium-6-deuteride has also been tested. The alternative meaning is an obsolete type of single-stage nuclear bomb that uses thermonuclear fusion on a large scale to create fast neutrons that can cause fission in depleted uranium, but which is not a two-stage hydrogen bomb. This type of bomb was referred to by Edward Telle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

September 11, 2001 Attacks
The September 11 attacks, also known as 9/11, were four coordinated Islamist terrorist suicide attacks by al-Qaeda against the United States in 2001. Nineteen terrorists hijacked four commercial airliners, crashing the first two into the Twin Towers of the World Trade Center in New York City and the third into the Pentagon (headquarters of the U.S. Department of Defense) in Arlington County, Virginia. The fourth plane crashed in a rural Pennsylvania field during a passenger revolt. The attacks killed 2,977 people, making it the deadliest terrorist attack in history. In response to the attacks, the United States waged the global war on terror over multiple decades to eliminate hostile groups deemed terrorist organizations, as well as the foreign governments purported to support them. Ringleader Mohamed Atta flew American Airlines Flight 11 into the North Tower of the World Trade Center complex at 8:46 a.m. Seventeen minutes later at 9:03 a.m., United Airlines Fli ...

Operation Grapple
Operation Grapple was a set of four series of British nuclear weapons tests of early atomic bombs and hydrogen bombs carried out in 1957 and 1958 at Malden Island and Kiritimati (Christmas Island) in the Gilbert and Ellice Islands in the Pacific Ocean (modern Kiribati) as part of the British hydrogen bomb programme. Nine nuclear explosions were initiated, culminating in the United Kingdom becoming the third recognised possessor of thermonuclear weapons, and the restoration of the nuclear Special Relationship with the United States in the form of the 1958 US–UK Mutual Defence Agreement. During the Second World War, Britain had a nuclear weapons project, codenamed Tube Alloys, which was merged with the American Manhattan Project in August 1943. Many of Britain's top scientists participated in the Manhattan Project. After the war, fearing that Britain would lose its great power status, the British government resumed the atomic bomb development effort, now codenamed High E ...

Malden Island
Malden Island, sometimes called Independence Island in the 19th century, is a low, arid, uninhabited atoll in the central Pacific Ocean, about in area. It is one of the Line Islands belonging to the Kiribati, Republic of Kiribati. The lagoon is entirely enclosed by land, though it is connected to the sea by underground channels, and is quite salty. The island is chiefly notable for its ancient ruins, stone architecture, its once-extensive deposits of phosphatic guano (exploited by Australian interests from 1860–1927), its former use as the site of the first British thermonuclear weapon, H-bomb tests (Operation Grapple, 1957), and its current importance as a protected area for breeding seabirds. The island is designated as the ''Malden Island Wildlife Sanctuary''. In 2014 the Kiribati government established a fishing exclusion zone around each of the southern Line Islands (Caroline Island, Caroline (commonly called Millennium), Flint Island, Flint, Vostok Island, Vostok, ...

Nature
Nature is an inherent character or constitution, particularly of the Ecosphere (planetary), ecosphere or the universe as a whole. In this general sense nature refers to the Scientific law, laws, elements and phenomenon, phenomena of the physical world, including life. Although humans are part of nature, human activity or humans as a whole are often described as at times at odds, or outright Anthropocentrism, separate and even superior to nature. During the advent of modern scientific method in the last several centuries, nature became the passive reality, organized and moved by divine laws. With the Industrial Revolution, nature increasingly became seen as the part of reality deprived from intentional intervention: it was hence considered as sacred by some traditions (Jean-Jacques Rousseau, Rousseau, American transcendentalism) or a mere decorum for divine providence or human history (Hegel, Marx). However, a vitalist vision of nature, closer to the pre-Socratic one, got reborn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asia Times Online
''Asia Times'' (), formerly known as ''Asia Times Online'', is a Hong Kongbased English language news media publishing group, covering politics, economics, business, and culture from an Asian perspective. ''Asia Times'' publishes in English and simplified Chinese. History The Hong Kong website is self-described successor to Bangkok-based print newspaper ''Asia Times'' that was launched in 1995 and closed in mid-1997, using the domain asiatimes.com. ''Asia Times Online'' was created early in 1999, at atimes.com, describing itself as a successor in "publication policy and editorial outlook" to the print newspaper ''Asia Times'', owned by Sondhi Limthongkul, a Thai media mogul and leader of the People's Alliance for Democracy, who later sold his business. The new publishing company is Asia Times Holdings Limited, incorporated and registered in Hong Kong. Many reporters from the ''Asia Times'' print edition continued their careers as journalists, and a group of those contributo ...

2006 North Korean Nuclear Test
On October 9, 2006, North Korea performed its first nuclear test, detonating a plutonium-based device underground. On October 3, 2006, North Korea announced its intention to conduct a nuclear test. The blast is generally estimated to have had an explosive force of less than one kiloton, and some radioactive output was detected. United States officials suggested the device may have been a nuclear explosive that misfired. An anonymous official at the North Korean Embassy in Beijing told a South Korean newspaper that the explosive output was smaller than expected. Because of the secretive nature of North Korea and small yield of the test, there remains some question as to whether it was a successful test of an unusually small device (which would have required sophisticated technology), or a partially failed " fizzle" or dud. A scientific paper later estimated the yield as 0.48 kilotons.Lian-Feng Zhao, Xiao-Bi Xie, Wei-Min Wang, and Zhen-Xing Yao,Regional Seismic Characteristics o ...

Gerboise Verte
''Gerboise Verte'' (; ) is the codename for a French nuclear test conducted on 25 April 1961. The test took place at the ''Centre Saharien d'Expérimentations Militaires'' (CSEM), 50 km south of Reggane, Algeria, then a French department and was designed as an atmospheric test. This was the fourth French nuclear atmospheric test, after '' Gerboise Bleue'', '' Gerboise Blanche'', and ''Gerboise Rouge''. History In 1957, the French government decided to create experimental nuclear testing facilities in the Sahara. To this end, 108,000 square kilometers of land were allocated to the French Ministry of Defense for the first French nuclear experiments. The (CSEM) for atmospheric testing was set up in Hamoudia some 50 km south of Reggane, an oasis in the south of the Grand Erg Occidental, 700 km from Colomb Béchar. The (CEMO) was later built in the Hoggar Mountains, near In Ekker, 150 km north of Tamanrasset, to carry out underground nuclear tests. Between ...

Uranium Hydride Bomb
The uranium hydride bomb was a variant design of the atomic bomb first suggested by Robert Oppenheimer in 1939 and advocated and tested by Edward Teller. It used deuterium, an isotope of hydrogen, as a neutron moderator in a uranium-deuterium ceramic compact. Unlike all other fission-bomb types, the concept relies on a chain reaction of slow nuclear fission (see neutron temperature). Bomb efficiency was harmed by the slowing of neutrons since the latter delays the reaction, as delineated by Rob Serber in his 1992 extension of the original ''Los Alamos Primer''. The term hydride for this type of weapon has been subject to misunderstandings in the open literature. While "hydride" might imply that natural hydrogen (which is mostly Isotopes of hydrogen, H), is used; only deuterium (H) has been used for the bomb Pit (nuclear weapon), pits. Likewise, a "hydrogen bomb" uses deuterium and occasionally tritium. Two uranium deuteride bombs are known to have been tested, the ''Ruth'' and ''Ra ...
