...state that if a room is not cleaned it will perpetually become more messy and unsystematic with time. The third law of thermodynamics would be that when a entropy reaches a constant value as it approaches zero. Fossil Fuel pros and cons, the pros of using fossil fuel is that we are able to develop new technology to harness energy from this natural source. Fossil fuel is cheap and there are no other things needed to gather energy from this fuel, it is considered being a reliable source of energy. Think about load-based needs, fossil fuel is more preferred then other sources of energy that are consider being unreliable. The cons of using fossil fuel are that it contributes to the worsening of global warming. Fossil fuel is not an environment-friendly source of energy even dough it is consider a natural source. It is the main contributors in global warming due to it releasing high amounts of carbon. Nuclear energy unlike fossil fuel does not release smoke in the atmosphere. It is ran off electricity by splitting atoms in a sequence of nuclear reactions, better known as nuclear fusion. The white plumes you see rising from cooling towers are non-more than steam; nuclear energy is considered to be carbon-free and produces more electricity unlike solar or wind. The con of using nuclear energy is that it can be used for weaponry, as in...

...letter to the United States president of the time, Franklin D. Roosevelt, concerning the research of splitting a uranium atom that could lead to the development of an atomic bomb in Germany. In the letter, Einstein wrote,”It may be possible to set off a nuclear chain reaction in a large mass of uranium, by which large amounts of power and new radium like elements would be generated.” He continued,” This new development could lead to the creation of bombs, and as it seems, but less likely, the construction of an even bigger, new type of bomb.” President Roosevelt, although skeptical at first, decided to go through with the research and in 1941 the Manhattan Project was born. Four years later on August 6, the United States Dropped the first nuclear atomic bomb on the Japanese city of Hiroshima wiping out 90 percent of the city, killing more than 80,000 people, and later tens of thousands more. Then again on August 9, another bomb was dropped on the city of Nagasaki and killing more than 40,000. 6 days later, the Emperor of Japan announced Japan’s official surrender to the United States in World War II. The effects and after effects of the the two bombs dropped shocked the entire world, even those a part of the Manhattan Project. The Japanese Emperor Hirohito described the bombs as the ”new and most cruel bomb.” This research paper will discuss the pros and cons of the use of nuclear weapons among different countries and how they affects the lives of those living within them. ...

...existing one.” 2. Nuclear power is a source of energy that occurs when a neutron is launched at an unstable atom like uranium or plutonium. A cool fact about nuclear power is that it is a scientific discovery that was funded by the military. The US called it the Manhattan project. The project existed during WWII to create a bomb that would scare the world into peace Nuclear power is used in many ways to create power and to this there are many advantages and disadvantages, there are even some accidents but in the end there are more pros than there are cons. We talk about clean energy and most of you think of water or wind power, but there are some big drawbacks to these that nobody seems to ever discuss. Body I. What it’s used for [pp: 2Einstein]Nuclear energy is used to make power for many things. Many countries such as France and Japan have already changed most of their power to nuclear power and minimized the amount of fossil fuel used to create power. Many of the major navies in the world use this as a way to dominate the seas. The main reason that we don’t want to use fossil fuel is that it creates green house gases that may or may not be causing global warming but they do cause pollution in their immediate area with sulfur and other toxic chemicals. II. How it works [model: reactor][pp:3,atom]Nuclear power is when you harness the power of radioactive metals decaying. All radioactive means is that an element...

...Technology – Boon or Bane? Posted on August 25, 2011by Sumukh Naik Technology is one of the greatest invention of mankind.It is so powerful that it shapes our thinking and our way of life within no time.It is ever evolving.Technology is a tool invented and sharpened by humans to make their life easier.Those who know the correct application of technology, be it any sphere of activity, have managed to make lives easier for themselves and to some extent also for others. I feel the best technological breakthrough was the invention of computers which basically led to further advancement in technology viz the creation of many softwares and hardware. Technology has gifted mankind with various boons but look closely and you will realise that technology have blessed mankind with two very important aspects – facility of communication and creation of time. Creation of phone, fax, paging services, mobile services, video conferencing etc are few of the facilities that the human mind has been able to conceive with the aid of technology.All have played a very important part in making the world a ‘Global Village’. Technology has ensured that one can easily communicate with anyone on land, in air(aeroplanes) or even when the person is under the calm waves of dark deep-sea (submarines). But the Time Creation aspect of technology has now posed a challenge and threat which very few had ever thought of. Computers – They have evolved rapidly at the rate of knots.

...Nuclear Energy Research Paper Global warming is a major issue in today’s world that affects many people, animals, economies, and society as a whole. What is global warming? Global warming is the rising average temperature of Earth’s atmosphere and oceans and its projected continuation. It’s been constantly rising over the past 100 years because of major contributions which include: greenhouse gases (especially CO2) being emitted, industrialization, burning of fossil fuels, and the increase in population. Global warming was first discovered in 1896 by a Swedish scientist named Svante Arrhenius who proposed an idea that there is a relation between atmospheric carbon dioxide concentrations and temperature. He later then described, by comparing carbon dioxide levels, infrared absorption, surface temperature of the earth, and human activity, that global warming would rise. Other scientists didn’t believe this idea stating that natural forces would cancel out human activity that releases carbon dioxide. It wasn’t until 1988 that it was finally acknowledged that global warming is present because of how much warmer it was than the 1800s. Since then, the Intergovernmental Panel on Climate Change was founded which looks at scientific, technical, and socio-economic information that relates to human induced climate change and figures out plans and ideas to decrease and slow down the rate at which the climate is getting hotter. However, there are still disagreements to this day whether or...

...Given past events, nuclear power technology is seen by many people as the means to make war, death, bombs, and destruction. These are comparitive rarities to the good that nuclear energy poses for our future, and its capacity for clean efficient energy generation. Almost all of the energy produced today from nuclear is in the form of electricity, comprising 16% of global production. The number doesn't seem to be that large, but when taking into account the energy used on the entire planet, and the capacity to better the nuclear industry for the future we find ourselves wondering how vital it really is to our livelyhood. One could say that the development of nuclear is vital because of global warming threats. Since our combustion of fossil fuels produces carbon in the atmosphere, resulting in rising heat over time. Nuclear provides a form of noncombusting renewable energy that if prudently researched and implemented provides an alternative to polluting engines of the past. This warming fear is a large reason nuclear power is a growing idea. The technology is not simple to do, the production is a very meticulous process, wielding great power for good and great danger. The process requires strong regulation. With such a high risk, high reward scenario, we as humanity's hope for a better tomorrow must weigh the pros and cons to find if we are able to prudently expand and increase research towards safety and efficiency. Producing nuclear energy is not as simple as taking it from...

...What is Hinduism? It is the true culture of Indians in India. Many call it "A way of life." It is not an organized religion like Christianity or Islam. It has no founder. It has no Pope. It has no hierarchy. Just a lot of scriptures. In Hindu scriptures, you are actually studying about the history and culture of India, like in 66 books of the Holy Bible you are actually studying about the culture and history of the Jews. Hinduism and Judaism are mothers of all modern religions in the world. Buddhism, Sikhism and to some extent Jainism and Zoroastrianism came from Hinduism. Of course, Jainism existed during Rig Vedic Period. Statues of Rishabha, the first Thirthankara and founder of Jainism was found in the Mohenjadaro, Harappa excavations. Islam and Christianity came from Judaism. Judaism, Islam and Christianity have Abraham as the common father figure. All three have many common prophets. There is even mention about Jesus Christ many times in the Holy Koran. Coming back to Hinduism, C.S. Lewis, the great author and theologist wrote, finally it will come to two religions. Hinduism and Christianity. The first [Hinduism] will grow absorbing ideas and concepts from everywhere and later [Christianity] will keep away from everything that is foreign to it. What C.S. Lewis wrote is very true. Hinduism cannot be destroyed, even if we burn every Hindu scripture and kill every Hindu theologian on earth. Hinduism or Hindu Culture is a very dynamic living, breathing Reality. Strength of Hinduism...

Lutgens and Tarbuck Textbook: Earthquakes and Structures (Chapter 6) * Know the definition of an earthquake (pg. 190). --ground shaking caused by the sudden and rapid movement of one block of rock slipping past another along fractures in Earth’s crust called faults * Know the difference between the focus and epicenter of an earthquake. Which is located at the source of the earthquake? Which is located on the surface of the earth directly above the source? --Focus=Earthquakes tend to occur along preexisting faults where internal stresses have caused the crustal rocks to rupture or break into two or more units. The location where slippage begins is called the hypocenter, or focus. --Epicenter=The point on Earth’s surface directly above the hypocenter * Understand the concept of elastic rebound. What is it? How are earthquakes produced via elastic rebound? * --Elastic rebound=At some point, the stress along the fault overcomes the frictional resistance, and slip initiates. Slippage allows the deformed ( bent) rock to “ snap back” to its original, stress- free, shape; a series of earthquake waves radiate as it slides. Reid termed the “ spring-ing back” elastic rebound because the rock behaves elastically, much like a stretched rubber band does when it is released. * Know the three basic types of seismic waves...

PSYCHOLOGICAL CONSIDERATIONS Daniel 32 X. SOCIOLOGICAL AFFECTS Daniel 36 INTRODUCTION Technology is applying science to improve on an existing task to make it easier. Technology can be used for all types of things, from science applications to mechanical engineering. Changing the way something is done often improves it. This is the heart of technology. Technology has evolved into nanotechnology. Nanotechnology is a “technology executed on the scale of less than 100 nanometers, the goal of which is to control individual atoms and molecules, especially to computer chips and other microscopic devices.” Nanotechnology may one day improve the quality of life, thereby extending the life span of humans, by using “small autonomous robot, or nanobot, that can be sent into the human body to repair cells and cure cancers.” (nanotechnology). It is the continued advancement in nanotechnology that has been used to downsize the combative drones that we associate with the war, to the small Unmanned Aerial Vehicles (sUAV), and into the hands of hobbyist all over the world. The technology for radio-controlled aircraft has been around for decades with guidelines set forth from the FAA that restricted the use of the radio-controlled aircrafts to specified areas.

The end of the Cold War is usually seen as the beginning of the contemporary era in world politics which is the subject matter of this book. It is, therefore, appropriate that we begin the story with a discussion of the Cold War. The chapter shows how the dominance of two superpowers, the United States of America and the Soviet Union, was central to the Cold War. It tracks the various arenas of the Cold War in different parts of the world. The chapter views the NonAligned Movement (NAM) as a challenge to the dominance of the two superpowers and describes the attempts by the non-aligned countries to establish a New International Economic Order (NIEO) as a means of attaining economic development and political independence. It concludes with an assessment of India’s role in NAM and asks how successful the policy of nonalignment has been in protecting India’s interests. The end of the Second...
