Humans Discover Nuclear Fission
It seems as though our fellow Earthlings deserve more credit then we
have given them in the past; they have seemingly discovered the so
called, “Nuclear Fission.” The situation on earth has not been
reported on in over a century, yet they have advanced rather rapidly;
in fact more than they can handle.
Nuclear Fission, as discovered here in Trantor, has both benefits and
drawbacks in society. However, earth is an obscure planet with
rather demanding creatures that in the past have used technology and
knowledge negatively. Within the last hundred years, this discovery
had made a rather large impact on the people of earth. Amateurs, as
they are, they have made their lives easier, yet harder with all the
unaccountable damage they have caused. Yet again, humans are
reprimanded as being irresponsible. If only they knew better.
Energy has become a difficult issue on the planet earth. Because
humans do not have magical powers like us, they have to have sources
to generate energy. The most popular sources of energy used on earth
are fossil fuels, including materials such as coal. However these
fossil fuels are said to be running out and so other sources have been
identified including solar power, wind power, and recently, nuclear
fission.
Nuclear Fission, essentially, is the process of splitting atoms with
releases of energy. An example of nuclear fission can be seen in
terms of radioactive material. When radioactive material decays,
protons and neutrons are pulled into arrangements where they are
tightly bound. At this stage, nuclear potential energy is lost, and
heat is released.. Humans have discovered that faster decay can be
produced by bombarding nuclei with other particles. An example of this
is Natural Uranium. When a neutron (The Human symbol N) strikes a
nucleus of isotope Uranium 235, the nucleus splits giving off,
simultaneously, both neutrons and energy. Furthermore, they have
picked up on the ‘Chain Reaction.” If neutrons from the fission of
one nucleus go onto split other nuclei, the number of nuclei
undergoing fission multiplies rapidly. Hence, lots of energy is
released in a sort space of time.
In certain aspects, this is a good thing. Small amounts of fuel can
provide a reasonably large amount of energy. This fuel used is rather
inexpensive and can be found worldwide....

...e diverted human effort to
develop peaceful applications of nuclear energy. As a result, nuclear
power reactors have been supplying energy for humans for several
decades now. Reactor accidents have changed public opinion to an
extent, and the future of nuclear energy is uncertain. Yet the energy
demand is on increase, and the public opinion may just change again.
Whatever the result of this discovery may be, let us hope that humans
will be more responsible and conscious in the future.

man, Sam not only satisfied with the present operation but also tried any possibilities to bring his business into another level, discount retailing. He eventually withdrew from Ben Franklin’s franchising and opened his own store incorporated with his new idea, Wal-Mart Discount City in Rogers, Arkansas, July 2 1962. Sam’s brilliant ideal and successful operation allows Wal-Mart expanded from one store to thirty-eight store cross-states within eight year. Wal-Mart went to public in 1970, and it became the first company to reach 1 billion within 9 years. Up to 2004 Wal-Mart has 4,906 store world-wild, and 9 billion in profit. Despite some of controversial issues about its operation approaches, Wal-Mart’s dramatic rapidly growth is phenomenal in business community, and its successful business model has been eulogized world-wild.
Nuclear energy must be a consideration for the future with the rapidly depleting supply of fossil fuels. This type of energy can be created through nuclear fission and nuclear fusion. Nuclear fission is the splitting of a heavy atom into two or more parts, releasing huge amounts of energy. The release of energy can be controlled and captured for generating electricity. Nuclear fusion involves bombarding hydrogen atoms together to form helium. In the long run, nuclear fusion has greater potential than fission.
Central Idea: Nuclear energy only contributes a small amount to the world’s electricity yet it has hazards and dangers that far out-way its benefits. There are many other alternative power producing sources that can produce energy more efficiently and more safely than nuclear power plants can.
Melissa Jordine said that “1949 proved to be a pivotal year,” and she would be correct (Cold War). It was the middle of the Cold War and tensions were high between the Soviet Union and the United States. The US had consistently opposed Russia’s communist government, but had become even more vehement in their hostilities once Vladimir Lenin, the leader of the USSR, announced his intentions to overthrow capitalist systems worldwide, which included the system that the United States boasted (Cold War). The American people knew they must resist the rising power, and the only feasible option that they saw to deter Soviet aggression was to maintain military superiority, namely through the singular possession of nuclear weapons. So it came as a terrifying shock when the Soviet Union detonated their own atomic bomb on August 29, 1949, ending the United States’ “atomic monopoly” and starting a race to develop better nuclear arms (Jordine, Hydrogen Bomb). The hydrogen bomb, or H-bomb, was a product of this race, and while its creation negatively impacted the environment, it served its intended purpose in the respect that the threat of its use prevented a nuclear war and allowed for the United States to retain its capitalist government.
In America, there is a hatred lurking around in almost every corner of the nation; a discrimination and social bias that preys on the lives of innocent Muslims. Some people fear for their lives when they see a Muslim board a plane that they’re going to go on. Politicians are using that fear to fuel their popularity in elections. This prejudice even started to become a form of patriotism in the eyes of a concerning number of Americans. A lot of Muslims fear for their own lives in America because they are being looked down upon and even targeted by some people. This fear and hatred against these innocent Muslims are defined as Islamophobia. I believe that this amount of Islamophobia that is happening in America

Post September 11, 2001 the life of a Muslim woman living in America changed forever. Islamophobia is the prejudice against Islam or Muslims. Islamophobia is not a new concept it has roots hundreds of years ago, however after 9/11 it became much more prevalent in America. Following 9/11 Western media used Islam and Muslim woman who covered to inflict fear in American citizens. Western media framed Islam as a dangerous and hateful religion that needed to be stopped. At the same time the media became obsessed with Muslim woman who veiled and wanted to save these woman from their oppression. However, these articles written about the oppressed Muslim woman did not feature Muslim woman and their experiences veiling. They were not given a voice on the subject of their lives. The people writing these articles were very ethnocentric. They did not consider the religion or culture of these Muslim woman choosing to veil and the empowerment it may give some of these woman. I would like to spend time looking at Westerns media portrayal of
On August 2nd of 1939, Famous scientist Albert Einstein sent a letter to the President of the United States, F.D. Roosevelt, regarding his thoughts on uranium and how America could use it for wartime and to tip the scale. Einstein believes the uranium can be used in bombs to take down ports and waterside targets, stating that the bombs would be too heavy for air travel. Einstein hopes to get the president onboard with his idea because of the prowess the president has to convince higher authority like congress and various government departments. Although he’s confident in the uranium's power and pros, einstein also notices the cons of the element as well.
For over a decade fear filled statements about Islam has made headlines throughout Western civilization. Nations have banded together criticizing, attempting to regulate and blaming the entirety of Islamic faith after the events of 9/11. This can be seen in stereotypes
Characterized as a hatred of Islam, or feelings of fear and abhorrence toward Muslims (Samari 1920), Islamophobia in the United States has increased at rapid rates, and as a result, has caused negative health implications in the American Muslim community. Reinforced by the terrorist attacks in Orlando, San Bernardino, Paris, and the sudden emergence of The Islamic State of Iraq and Syria (ISIS), Islamophobia is not concerned with anti-Muslim sentiment only, but is instead representative of a history of U.S. policy that has reinforced xenophobic and discriminatory attitudes toward Muslims starting from the 17th century (Samari 1920). Because of this enduring stigmatization and subsequent damage to interpersonal and structural systems (Samari
Discrimination is a very serious problem as it affects your daily life. Islamophobia is what I have chosen for my advertisement. Everybody knows that not all Muslims are terrorist but choose to believe otherwise. This has led to many conflicts and harsh judgments on individuals. Severe depression can be found in some of the teens life has they were bullied for wearing a hijab or because of their religion. I have made this advertisement to support all of the Muslims out there who deserve better.
A poll that was conducted by the YouGov found that “on average, 55 percent of those it surveyed held an ‘unfavorable’ opinion of Islam” reported by Elizabeth Whitman on her article on “What is Islamophobia?”. Islamophobia is a recently added term that is defined as the fear of any Islamic activities and their practitioners. There is clear evidence of the influences from Islamophobia especially in the US. After the 9/11 attack, controversies during the 2008 elections of building mosques near the attack site, and more recently the Paris Terrorist Attack, Islamophobia had spiked up viscously. According to recent studies by the FBI, the hate crime incidents from “Anti- Black”, “Anti-Jewish”, and “Anti-Gay” had been on a steady decline as each year progressed since a decade ago. On the other hand, the “Anti-Islamic Hate Crime Incidents” in the US had crescendo. After the great spike of ’01, as each year passd, there had been no relent on the Muslim

Nuclear energy is generated by a process called fission. Fission occurs within the reactor of a nuclear power plant when a neutron is fired at an atom of uranium causing it to split and release subsequent neutrons.1 These are able to crash into other uranium atoms causing a chain reaction and releasing a great deal of heat energy.
