Atomic Bomb :: essays research papers

Atomic Bomb On August 2, 1939 Albert Einstein wrote to President Franklin D. Roosevelt. This was right before the start of World War 2. In this letter Einstein and several other scientists told Roosevelt of the efforts Hitler was making to purify U-235 in which he hoped to make an atomic bomb. This is when the United States started the Manhattan Project. This was the project of making an atomic bomb. In the project many brilliant minds were used. The most famous of these people is Robert Oppenheimer. He was the major person behind this project. He basically ran the operation and oversaw the hole project from start to completion. Other great people like H.C. Urey, Ernest Lawrence, Isidor Rabi, and Ken Bainbridge also worked on the project and put just as much into it. The most complicated process was the process of getting enough uranium to sustain a chain reaction. In that time it was very hard to extract U-235. The ration of Uranium ore to the Uranium metal is 500:1. Then out of this Uranium metal 99% of it is U-238 which is non-fissionable. Finding a process to refining the Uranium was the first step in developing the atomic bomb. A massive enrichment laboratory/plant was built in Oak ridge, Tennessee. H.C. Urey and other associates at Columbia University devised a system that separated the Uranium using the principle of gaseous diffusion. Ernest Lawrence shortly following this invention came up with a process using magnetic separation. This process was quicker then the first. After the Uranium metal was separated form the Uranium ore it is put into a gas centrifuge to separate the U-235 and U-238. The first step of building an atomic bomb was completed. They now had the U-235 to build a bomb. Over the course of six years, 1939-1945, scientist worked on equations to make the U-235 into a bomb. It took some of the greatest minds to make these formulas. At the end of the six years and after spending $2 billion they had what they thought was a working bomb or a very expensive dud. At 5:29:45 (Mountain War Time) on July the 16th, 1945 the "Gadget", the code name for the bomb, was tested in the Jemez Mountains in northern New Mexico. This was the first atomic bomb ever detonated. The Gadget caused a white blaze to stretch across the skies of New Mexico.

Biomedical Technology | Born and raised in India but now living in Chicago, I am a young man who is deeply engaged with the crossover between biochemical and biomedical research, on the one hand, and business realities on the other. My long term goal is to become an independent researcher with my own business in the area of biochemistry and biochemical research. I feel that I have already distinguished myself as a physical scientist, and now I seek the other leg upon which my long term goal is based.I especially look forward to studying in the GSB in the areas of marketing and finance as well as social responsibility and progressive political agendas in the business world. I completed my undergraduate and Master’s level studies in my native India. Then I came to XXXX University where I completed my Ph. D. in Chemistry in December of 2005. This, of course, is the single strongest aspect of my application because of the utility of this terminal scientific degree for the business world, staying abreast of the business aspects of scientific developments in chemistry and micro- biology.I am also very pleased to have received the Doctoral Dissertation Completion Award in March, 2005, based on evaluations by an interdepartmental committee of faculty members. I have authored two research papers coming out of my doctoral dissertation in 2006 that were published in the journal Biochemistry. I am the first author of both articles. Currently, I have the privilege of serving as a post doctoral research associate in the Hematology/Oncology Division of the Department of Medicine at the University of Chicago.I am also pursuing research on Acute Lymphoblastic Leukemia (ALL) and expect to receive funding from a private funding agency by next year. Two manuscripts from my postdoctoral work are in the pipeline. I will be the first author on one of the two papers. I am industrious and intelligent, with a sound educational background and a GPA of 3. 82. In fact, I am tenaciou s, and capable of a career that offers great challenges. I feel strongly that Loyola is the best place to prepare myself for making the greatest possible contribution to society through the promotion of biomedical research.With my own company my dream is to develop a specific concentration on only the most clinically relevant research. There are various reasons why XXXX’s GSB is my first choice. Most basically, I live in Chicago and I also like the flexibility of your program, but it goes far beyond that. I would feel especially privileged to become associated with your programs emphasis on the importance of values-based decision-making since business ethics and social responsibility stand at the center of my research curiosity.Nowhere, of course, is the need for social responsibility any greater than in the area of biochemistry. Your GSB Program will provide me with the solid foundation that I will need to someday manage my own business and to integrate business disciplines in increasingly creative ways that allow me to give full vent to my inspiration. I also identify with XXXX’s GSB in the focus on business issues in a global context. I ask for you help in becoming one of the highly responsible and morally sound business leaders of tomorrow in the field of biochemistry. I want to thank you for consideration of my application.

Psychoactive Drugs The Single Convention On Narcotic Drugs

In 1961 the UN adopted the Single Convention on Narcotic Drugs, where it was noted that the problem requires urgent and priority, and in 1984 in the Declaration on the fight against drug trafficking and drug abuse the entire conglomerate of problems, ranging from illicit manufacturing and trafficking to abuse, called shameful and disgusting crime. And it can be called a kind of ostrich policy† (The Single Convention on Narcotic Drugs of 1961). There are four key groups of psychoactive drugs: stimulants, depressants, opioids and hallucinogens. This classification is conditional because most psychoactive drugs have several effects on the psychological and physical activity of the body, depending on the dose and duration of use.] The use†¦show more content†¦Marijuana is used to heighten perception, affect mood, and relax. Many people think marijuana is harmless, but it is not. Signs of marijuana use include red eyes, lethargy, and uncoordinated body movements. The long-term effects may include decrease in motivation and harmful effects on the brain, heart, lungs, and reproductive system. People who smoke marijuana are also at increased risk of developing cancer of the head and neck. A pharmaceutical product, Marinol, that contains synthetic THC, is available as a prescription medication. It comes in the form of a pill (eliminating the harmful and cancer-causing chemicals present when marijuana is smoked) and is used to relieve the nausea and vomiting associated with chemotherapy for cancer patients and to treat loss of appetite in AIDS patients. (Definition of Marijuana Definition of Alcohol 2012) The aim of this essay is to compare and contrast two different psychoactive drugs, Alcohol and Marihuana, grounded on physical and psychological addiction they cause. Alcohol can be stimulant in small doses and depressant in large doses, whilst marihuana belongs to the hallucinogen group and, therefore, can be depressant depending on our mood Alcohol dependence is a leader in the structure of a substance abuse. The NHS estimates that just under one in 10 (8.7%) men in the UK and one in 20 (3.3%) UK women show signs of alcohol dependence (sometimes known as â€Å"alcoholism†), (The NHS

Aid For Illegal Immigrants Special Interests Or The Best...

Financial Aid for Illegal Immigrants: Special Interests or the Best Interests of Society? The mention of immigration in large groups can immediately engender heated debate as people, informed by their personal experience, pose simplistic solutions to the problem or mourn their absence in this highly complicated situation. To some degree, immigration creates two camps: those who believe immigrants should be embraced and those who perceive immigrants legal or otherwise, as a threat to society. While it may be easy for some to declare immigration a black and white issue, that illegal immigrants and their progeny should not be here, this ignores children born in the United States to illegal parents who have never known life in another†¦show more content†¦Instead many fall victim to opportunists who pay and treat employees poorly because reporting any illegal or unethical behavior places the worker’s residency in jeopardy. In many cases, the jobs available to undocumented workers result in families living in poverty for whom a college education is unattai nable. For â€Å"regular† students facing this situation there are government funds available because society recognizes that endemic poverty is unacceptable and that an educated workforce ultimately reduces poverty and the numbers needing public assistance. Another hurdle facing many citizen children of undocumented parents are states that attempt to prevent these children from attending college on â€Å"in-state† tuition because of their parent’s status. Undocumented children who are able to receive public assistance to continue their education may be those best capable of finding a viable, positive solution to the issue of illegal immigration in general. Given the rights and services already afforded this group (as children they are protected even if their parents are not) extending those services to college also seems the only logical step in the immigration quagmire. Penalizing legal citizens regardless of their parent’s status flies in the face of the Constitution. Literature Review In 2005 there were approximately 360,000 high school graduates between the ages 18-24 and 715,000 between 5-17, all of whom are undocumented youths

Report for Paradox of Affluence †Free Sample

Question: Describe about the Report for Paradox of Affluence ? Answer: The paradox of affluence is the manifestation of the saying that wealth cannot buy happiness. Still people continue to believe otherwise trying to get famous and rich. Often they tend to spend on things they generally do not need. Responsibility is the first step to happiness. The present economic problems of the United States are mainly due to the individual citizens deficit of financial thrift. Abraham Maslows hierarchy of needs is considered as one of the earliest psychological work on happy individuals and psychological trajectory (Stehling-Ariza, 2013). There are a few basic human requirements which when fulfilled yields the maximum effects on psychological health. Therefore, the research on happiness and wealth has been related to Maslows hierarchy of needs and has been analyzed individually below. Psychological Needs: The basic needs of human beings such as breathing, drink, food, sex, sleep, excretion and the physical and biological requirements needs to be fulfilled. When these needs are not fulfilled, people run after these needs and forget wealth and happiness. People in a natural disaster region are more concerned about food than anything else. Safety Needs: Not only physical but also social, economic, psychological and vocational. If the security needs of an individual are under threat, he will not be concerned about happiness or wealth anymore. If a person loses his job or family, his happiness will be at stake and any amount of wealth will be useless. Love and Belongingness Needs: Since human beings are social beings, their friends and family helps them to get through the various phases of life. If there is any lack of belongingness or intimacy in the relationships, it may lead to loneliness or depression. An unhappy person will not look for wealth; happiness will be his only pursuit (Pursuit of Happiness, 2010). Esteem Needs: Self-esteem is an important factor for an individual to identify his personal uniqueness. This can be achieved by the love of friends and family. The unique capabilities and talents of an individual give him immense happiness and psychological freedom, where happiness is nowhere related to wealth. Happiness can be achieved by easily if one learns how to be good, fruitful, happy fulfill potentialities, none of which depends on wealth. To identify and understand oneself as a human being and an individual deep inside gives the highest form of happiness.

Vietnam How And Why The United States Got Involved Essays

Vietnam: How And Why The United States Got Involved Vietnam: How and Why the United States Got Involved The conflict in Vietnam which is also called the Ten Thousand-Day War was an ongoing battle from 1945 to 1975. In the 30 years of fighting, the United States would lose over 57,000 men while Vietnamese dead numbered two million (Maclear 2). The Vietnam War is very interesting because many people have wondered how and why the United States got involved in a war that really didnt seem to concern them. American involvement officially began in 1950 when the US government recognized the Bao Dai government and began sending the French aid to fight off the communist backed Viet Minh led by Ho Chi Minh (Scheer 10). The French lost the war because it was not fully committed to a win policy (Scheer 10). The Bao Dai, anti-Communist nationalist alternative, whom the Truman and Eisenhower Administrations had backed, had failed to undercut the appeal of the Viet Minh (Scheer 11). The price of peace involved the surrendering of some portion of the country to the Communists, and the United States could not oppose since it had not become deeply involved (Scheer 12). The United States instead placed its hopes on a new anti-Communist nationalist alternative and his name was Ngo Dinh Diem. Diem accepted the offer and on July 7, 1954 his government was formally organized. This started a new phase of U.S. involvement in Vietnam. Senator John F. Kennedy recommended, in order to prevent the further spread of communism in Southeast Asia, that the French grant independence to South Vietnam, support the governments army, and whenever necessary[make] some commitment of our manpower (Scheer 15). The settlement at Geneva in July, 1954, did three things: 1) it ended the war; 2) divided Vietnam in half temporarily; and 3) called for peace and reunification of the country (Scheer 16). Diems government believed in tight central control to divert the nationalist revolution from Communist objectives (Scheer 21). During the first year of the new government, Diem crushed all sources of opposition left over from the Viet Minh (Scheer 21). By 1959, in the North, the Viet Minh had written off the possibility of the elections that they were supposed to get and turned to military means. This ended the illusory stability of the Diem regime (Scheer 46). Diem was aware that his government could not survive without the massive aid from the United States so he based his whole appeal on anti-communism (Scheer 56). But then, with the Communist danger the basis for assuring continued American aid, the secure countryside suddenly was overrun with Communist terrorists (Scheer 56). At the end of April 1960, eighteen Vietnamese nobles petitioned Diem to liberalize his regime. The petition said continual arrests had filled prisons to overflowing and asserted that a swollen Government bureaucracy was corrupt and inefficient (Scheer 59). In 1961 Edward Landsdale was sent to Vietnam to make an over-all study of the situation. He reported that the situation was near total collapse and that if the policies of the Diem government and its advisers continued to be pursued the country would soon be lost (Scheer 60). It was then decided to increase the Vietnamese Army from 150,000 to 250,000, which was a direct violation of the Geneva Accords, to concentrate its training on counter-insurgency (Scheer 62). The final incidents that led to the coup were a train of abuses, no single one of which was necessarily more important than any other, even though the dramatic Buddhist crisis is frequently cited as the final straw; it was one straw, a dramatic on. On November 1, the generals staged a coup and in the end Diem was killed (Trager 179). In the spring of 1961, the magazine press began to revise its picture of Diems government (Scheer 66). Jerry Rose, who was an expert on Vietnam, accepted the containment policy after Diems removal and supported the overriding necessity for stopping the spread of communism in Vietnam. He says: To sum up: one solution now for the U.S. appears to be a show of power in South Vietnam which would pave the way toward a compromising settlement. But is the risk of a power-play warranted? Southeast Asia has
