...What is interstellar travel? Interstellar space travel is manned or unmanned space travel between different star systems, in comparison with space travel to other bodies in the same star system. It is invariably more difficult, as the time and distance scale for such an endeavour is almost unimaginable Why we want to visit other stars? The group identified five key factors as high-level motivations for the exploration of distant space: • Human survival: ideas related to creating a legacy for the human species, backing up the Earth’s biosphere, and enabling long-term survival in the face of catastrophic disasters on Earth. • Contact with other life: finding answers to whether there is other life in the universe, whether “intelligent” life exists elsewhere in the galaxy, and at a basic level, whether we are alone in the universe. • Evolution of the human species: exploration as a human imperative, expansion of human understanding and consciousness through space exploration. • Scientific discovery: breakthroughs in scientific understanding of the natural universe, a pursuit for knowledge. • Belief and faith: a search for God or the Divine, a need to explore beyond Earth’s atmosphere as a part of natural theology or as found through religious revelation. These drivers for exploration were identified through group discussion as the most significant, high-level reasons why human societies and individuals would undertake the exploration of space over long timescales...

...Essay 1 Energy Independence 9/28/2011 Persuasive Writing Charles Mountin Thesis Statement America needs to achieve energy independence and reduce its dependence on foreign oil. Abstract The United States need to lower its dependence on foreign oil. The U.S. dependence on foreign oil has created a huge trade deficit that puts billions of U.S. dollars into the hands of countries that are not U.S. allies. This dependence also could lead to an economic downturn if there is another spike in oil prices. The U.S. needs to find alternatives to foreign oil that are environmentally sound and U.S. made to achieve energy independence. America needs to find new energy sources and better energy conservation to meet its future energy needs. As of now America is far too dependent on foreign oil for its main energy source. Many experts say that the world is at peak output for oil right now and will be decreasing into the future. Right now the world has about 6.7 billion people, but by 2050 the estimate for world population is more than 9 billion people. That means we need a lot more oil than we now produce and our production capacity is already almost at its peak. If are still powering our cars, factories, and homes with oil when oil starts to run out we will be in a lot of trouble. In 2008 when oil supplies were near capacity the price of gas shot up to over $4.00 a gallon and I could barely keep up with my bills because of the extra money spent on gas. The price spike also...

These gravitation pulls of the sun and the counter pulls of the planets are called centrifugal forces. The planets revolve round the sun in their own specific orbits. These planets could be arranged in an order based on their distance from the sun. The nearest to the sun is Mercury and the next is Venus. Third comes the Earth. Later in the same order come Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. Pluto is the most distant planet. If the are arranged in the order of size, the order would be ; 1. Jupiter, 2.

...Various other models predict the nation's vulnerability. Bangladesh is the nation most vulnerable to global climate change in the world, according to German Watch’s Global Climate Risk Index (CRI) of 2011. This is based on the analysis of impacts of major climate events that occurred around the world in the twenty-year period since 1990. The reasons are complex and extremely intertwined. Located at the bottom of the mighty GBM river system (comprising the Ganges, the Brahmaputra and the Meghna), Bangladesh is watered by a total of 57 trans-boundary rivers coming down to it: 54 from neighbouring India and 3 from Myanmar. The country, which has no control of the water flow and volume, drains to the Bay of Bengal over 90% of the total run-off generated annually. Coupled with the high level of widespread poverty and increasing population density, limited adaptive capacity and poorly funded, ineffective local governance have made the region one of the most adversely affected in the planet. There are an estimated one thousand people in each square kilometre, with the national population increasing by 2 million people each year. Almost half the population is in poverty (Purchasing Power Parity of $1.25 per person a day). Hence these people do not have the ability to respond to a natural disaster and the government cannot help them.[2] Effects[edit] It is projected that, by 2020, from 500 to 750 million people will be affected by water stress caused by climate change around the world...

...is electricity and heat generated from solar, wind, ocean, hydropower, biomass, geothermal resources, and biofuels and hydrogen derived from renewable resources.” Renewable energy resources and significant opportunities for energy efficiency exist over the world. Compare to other traditional energy resources like fossil fuel, which are concentrated in a limited number of countries. The rapid development of renewable energy and energy efficiency, and the technological diversification of energy resources, would provide a sustainable and stable supply of energy and a significant growth in economy for the world in a foreseeable future. History of Renewable Energy Prior to the development of coal in the mid 19th century, nearly all energy used was renewable. The oldest known use of renewable energy, in the form of traditional biomass to fuel fires, dates from 790,000 years ago (K. Kris, 2013). The second oldest usage of renewable energy is using the wild to drive ships over water. This can be traced back 7,000 years ago, to ships on Nile (The Encyclopedia of Alternative Energy and Sustainable Living, 2013). Moving into the time of recorded history, the primary resources of traditional renewable energy were human labor, animal power, water power, wind and firewood (traditional biomass). By late 19 century, people concerned of running out of coal, so they promoted experiments with using solar energy. The development of solar engine continued until...

...Ken Hayes EDU-450-O101 Classroom Engagement and Management August 11th 2013 Shica Little A case studies a student's disruptive behavior. I’d like to take make a case study of a person I shall call Max. Now Max is a student who is normally a good student but has a I think I know everything type attitude so sometimes he becomes a disruption for he likes to show off to the class with his storehouse of knowledge and can sometimes test the teacher’s patience. In this case study I shall go through the behavior cycle as listed in our textbook, “Lee Canter’s Classroom Management for Academic Success.” For instance the first part of the cycle mentions using explicit directions or to communicate your instructions clearly and that a teacher cannot afford be vague when issuing directions in what he/she would like to have the class do. In this case, the teacher tells the class to go to their seats and begins to work on their worksheet on the planet Saturn. Max starts out going to his seat but stops to make a commentary on Debbie’s attire and then gets to his seat and then starts his assignment but then stops his work and starts to tell the class all he knows about Saturn. Now according to the text he did do what he was told but he did it his way and on his time frame. This is because the teacher did not give explicit enough instructions. A sample of this would be, class, go directly to your seats to not talk and get to work on your worksheet on the planet...

...Aurora Borealis (Northern Lights) By: Adriana Zavala They are many myths about the Aurora Borealis (Northern Lights), named after the Roman goddess of dawn, Aurora, and the Greek name for the north wind, Boreas, by Pierre Gassendi in 1621.The Lapps or the Saami people that were a closely related race of the Finns’ who lived in Lappland, in what is officially Northern Finland, Sweden, and Norway traditionally believed that the Aurora Borealis “were the energies of the souls of the departed. When the fires blazed in the skies, people were to behave solemnly, and children were admonished to quiet down and be respectful of the fires. It was believed that whoever disrespected the fires incurred bad fortune, which could result in sickness and even death” The Lapps believed these fires to have magical effects; Lappish shaman drums often have runes illustrating the fires to connect their energy. The lights were believed to have a serene effect on arguments, and the time of the fires was beneficial to problem solving. The Lapps also had a belief that if you whistled under the Aurora Borealis, then the lights would take you away with them (1). An American history on the Aurora Borealis took as an event. After the battle of Fredricksburg, the Aurora Borealis could be seen. The army took is it as God’s sign to show that he was on their side throughout the battle. It is very unusual to see the Aurora Borealis in Virginia (2). The Aurora Borealis is seen in many ways. One as a diffuse...

...obvious enthusiasm was infectious as he talked about the impact of Shoemaker-Levy 9 on Jupiter. Images of the impacts on Jupiter, taken with several different instruments, were presented. Unfortunately, no one commented on what the Jovian impacts told us about Jupiter's structure. Duncan Steel narrated a chilling segment on the deleterious global effects which would result from the impact of a several kilometer diameter object with New York City as the bullseye. David Morrison commented on the probabilities of death by impact. He noted that there are few professionals working in locating near-Earth objects which might threaten us. A few results from probes sent to Halley's Comet in the mid-1980s, during its last passage through the inner solar system, were presented. Several proposed methods for deflecting objects on a collision course with the Earth were highlighted with attractive animations and interviews with folks like Edward Teller. David Morrison underscored some of the holes in current defense strategies. Statistics such as...

...Energy, Fossil Fuels & Alternative Energy 22 July 2012 In order to understand how energy is converted from one form to another we must first define energy as the ability to do work and “Energy can never be destroyed. Energy can be converted from one form to another but the total energy remains constant (Integrated Science)”. Now that we have defined energy we can go further as there are two types of energy. The first type of energy is Kinetic energy, and is related with motion. Examples of Kinetic energy would be wind, water, machines, and even thermal energy. Our second form of energy is potential energy or energy waiting to be used. To types of potential energy would be fossil fuels or nuclear. Within these two types of energy it can be converted into the same 5 different forms of energy: (1) Mechanical Energy: energy from machines; (2) Chemical Energy: energy produced through a chemical reaction (3) Radiant energy: energy in the form of radiation or in the absence of matter (4) Electrical energy: derived from electromagnetic interactions and (5) Nuclear: energy produced by a nuclear reaction. Energy can go from one type of energy to another through energy transfer and most energy becomes mechanical energy. An example of this would be a power plant. The plant first burns coal (Potential energy converted to kinetic energy) to boil water that in turn spins turbines that produces electricity. All the energy is transferred to the other but only 40% of the...

...The Global Solar World War is truly on now, with the Chinese Government starting investigation on the imports of solar polysilicon from Korean and US solar companies. Note, we had already predicted this some time back and listed the solar winners and losers in case the Chinese imposed duties. The US imposition of duties on Solar panel imports from China has raised the hackles of the Chinese Government which considers the solar industry to be strategic to its future growth. While it will not affect the Chinese exports in a big way considering the easy workarounds, it has the potential of making the Chinese Government react negatively. The biggest losers could be the Polysilicon companies and Solar equipment suppliers based in the USA. Note China imports huge volumes of the polysilicon raw material used in solar panels from USA and South Korea. The reason being the the quality made in these countries is better and the costs are lower. With the polysilicon spot prices crashing to below cost, around as low as $20/kg levels, US and Korean companies are being forced to change their LT contracts which were stuck at higher levels. The US Government recently imposed Anti-dumping duties against the Chinese solar panel companies with the total quantum of duties to reach around 35-36% for most of the Tier 1 Chinese solar panel players. This is more than what was expected by the solar industry and has led to a vociferous protest from sections of the Chinese Government. Not surprisingly,...

...petroleum and coal based energy over the past eighty years, and not until recently have countries found a way to make clean energy more affordable. In this paper I will discuss a few types of clean energy and how they effect not only the environment we live in, but the economy we live in as well. Solar power is a science that has been around for over two hundred years, and the first solar panel was invented almost sixty years ago (Gruen). It has not been until the past ten years that solar power and solar panels have emerged as a legitimate source of clean energy that is cost effective. Solar power not only cuts down on dangerous CO2 emissions into our atmosphere, but can create jobs needed to support and sustain our economy. Jobs would be needed not only for creation of solar panels, but installation and also maintenance. The first solar panels were created about 55 years ago in New Jersey by a group of scientists working for Bell Laboratories (Gruen). Since that time it has become cheaper and cheaper to mass produce the components needed to create solar panels, and thus driving a higher demand as companies and consumers become more cognizant of the impact of gas power vs. solar power. Wind power is another huge resource for creating green energy in virtually every country in the world....

...important ones are: Energy, Building and Purchasing. Green Energy is made of wind, tide and solar. Green Building is the process of building houses and offices that are efficient. Purchasing green just like it sounds. Green energy technology has always existed ever since civilization began. For instance, we have been utilizing water, wind, and the sun, among others for decades now. But of course, how we use these technologies now is completely different than what it was before. However, green technology has come again to the forefront because of the changes that our home, the Earth, has been experiencing thanks to our actions. There are different technologies that were developed that made “green” technologies feasible ones. What exactly are they? When we think about green energy, the first thing that comes to our mind is the sun. The center of the solar system, capable of generating near-infinite amounts of energy. Before, it is just being used for functions such as drying and heating, but now it is now used to harness electricity. Because of the previous strength of the sun, it is undisputedly the most intriguing green energy technology of all. The better news is that this technology is constantly improving. From solar panels to GREEN TECHNOLOGY 3 inverters, individual parts of the solar energy system are being improved, making it a better energy source for the future....
