War ll. The first and only times that nuclear weapons were used in battle was against Japan in 1945. The United States dropped two different style of nuclear weapons on two different Japanese cities. One bomb used plutonium while the other used uranium to create the explosions. The bombs were dropped on Hiroshima on August 6‚ 1945 and Nagasaki on August 9‚ 1945. Estimates of deaths within the four months after the bombings ranged from 150‚000 to 250‚000 or more. About half the deaths occurred

Stuxnet and the Future of Cyber War David Adams Legal and Ethical Issues in Computing CIS 4253 The discovery in June 2010 that a cyber worm dubbed ‘Stuxnet’ had struck the Iranian nuclear facility at Natanz suggested that‚ for cyber war‚ the future is now. Yet more important is the political and strategic context in which new cyber threats are emerging‚ and the effects the worm has generated in this respect. Perhaps most striking is the confluence between cyber crime and state

relatively small part of the budget; rather‚ the money and manpower were needed to produce weapons-grade plutonium and uranium. Gaseous diffusion was‚ at the time‚ the most efficient way of separating the 235 U and 92 238 U isotopes.1 92 The question of why scientists entertained the idea of a uranium bomb at all is an intriguing one. Bohr had already demonstrated that uranium‚ when undergoing slow fission‚ gives off neutrons. When those neutrons strike impure 238 U‚ a new element is produced:

Soviet border guards have the control to stop the smuggling of nuclear material ’s. With the Cold War being over‚ there is a huge stockpile of over 100 nuclear sites (See Appendix A). Russia‚ alone has an inventory of 1‚300 tons of highly enriched uranium (HEU)‚ and 165 tons of weapon usable plutonium. Such material is coming into high demand on the market. Terrorist‚ organized crime and countries with nuclear ambition‚ are high bid contenders for the material. The United States is also becoming

Ernest Rutherford Born on August 30th‚ 1871 in New Zealand‚ Ernest Rutherford accomplished to be one of many successful chemists throughout the world in the 19th and the 20th centuries. With his brilliant experiments he explained the puzzling problem of radioactivity and the sudden breakdown of atoms. In addition‚ he determined the structure of the atom and was first to ever split it. Rutherford’s great mind triggered innovations of new technology such as the smoke detector that saves many

Godzilla vs. the Giant Scissors: Cutting the Antiwar Heart out of a Classic Brent Staples wrote a very interesting article that caught my attention. It is about Godzilla and how the American cinemas took Godzilla and hid its true meaning. Even pop culture can relay moralistic messages by using tone‚ purpose‚ and subliminal. Pop culture such as movies‚ books‚ music‚ and television shows‚ normally are about fictitious things that we watch to get away from our everyday lives. Some on the other

Nuclear Advancements After the Manhattan Project When the first atomic bomb was detonated in Alamogordo New Mexico on June 16‚ 1945‚ all the scientists involved in the Manhattan Project understood the great destructive power of radio-active isotopes. Although the atomic bomb was a very destructive force our world would not be as good without it. Because of the government funding involved in the project coupled with the need for an atom bomb‚ much research that otherwise may not have occurred
