...about all the air that we breath on a daily basis. It was published on July 18,2017 and it is an non- fiction chemistry book. There is a lot of people that don’t understand what’s in all the air around us, and this book explains the history of our air in a way that people can understand what it is that we breathe everyday. I was one of the ones that didn’t know what is in the air or how long it could stay there in the atmosphere and we could rebreathe the same air that people from hundreds of years ago took in. It’s explains how and when each of the gas molecules found in the atmosphere and air were discovered and by who. I always thought that...

...only juniors in high school, investigated with curiosity. We know what cigarettes look like, but this peeked our curiosity. The smell came in waves along with the smoke from which seemed to crawl directly towards us. The smell being so pungent told us exactly to what curiosity lead us to, marijuana. Excited and scared our nerves jittered in our bodies as our mind raced with questions. The guys, all dressed in skinny jeans and various band T- shirts, looked us over cooly. They smiled and held up the calendric object as if to offer it to us. Overwhelmed by the offer, we stood frozen like statues. We finally moved after what seemed like years of time going by, but being only mere seconds in our buzzing reality. As we reached the group of three, our excitement seemed to dwindle as fear crept into our minds with each step. We knew not these guys; we had no clue to what they smoked. What could happen to us? Even with all of these questions, we continued to walk forward. Finally, meeting them close to a crowd of throbbing bodies, we stopped. The tallest boy of the three, an olive colored boy with deep emerald green eyes and shoulder length hair as black as coal, smiled brightly and politely as he asked our names. We answered behind girlish smiles. He, now verbally, asked us if we wanted a “hit” of the “joint”. Looking at each other for a log moment, we shook our heads answering no shyly. He shook his head and raised his boy shoulders as if to say “oh well”. Now, feeling dumb,...

...universe. It literally controls how our reality operates and how our existence came to be in this universe, it actually it what made our universe. When you think about physics you probably think about friction and forces but it is a much broader idea. Physics is what controls how the atoms that make up everything work with each other to form the things we see, the things we use, and even ourselves. Physics is a fundamental basis of our idea of the universe; yes there could be another parallel universe that has a different set of laws of physics but if it exists and we discover it physics will be there to help us understand the cause of this great phenomenon. Conduction, convection, and radiation are a processes of heat transfer and we experience these processes every day, some people might not realize it but these studies of physics are happening right now, all around us. Heat transfer is really just the transfer of energy and to understand how energy is transferred one must understand the physics of heat. “Conduction is the process of heat transfer in solids. If one end of a solid is heated, the particles of the solid gain kinetic energy thus moving faster. In a solid the particles are held together by strong forces of attraction. The only way in which the particles can move is to vibrate forwards and backwards. The increase in kinetic energy is an increase in energy thus forming heat.” Conduction is classified in two ways, thermal conduction and electrical conduction. Thermal...

...1. Theme – Understanding the environment of Mars Abstract Recent success of 'Mangalyan' (Mars Orbitor Mission) has made all of us proud of our scientists and engineers. The study of Mars' environment will help us in understanding more about our own environment. This text gives inputs on environment of Mars which can be correlated to the concepts learned by the students in class IX Science. The students are not supposed to memorize the facts and figures mentioned in the text, rather study the facts and figures with the above objectives in mind. Fig. 1: Mars Orbiter Mission Spacecraft getting in to Large Space Simulation Chamber for Testing Mars Orbiter Mission (M.O.M) Mars tugs at the human imagination like no other planet. The conditions in Mars are believed to be hospitable since the planet is similar to earth in many ways. Mars and Earth have almost equal period of revolution around the axis. Mars takes 24 hours and 37 minutes to complete equal period of revolution around the axis. While Earth takes approximately 365 days to orbit round the Sun, Mars takes 687 days for an orbit around the Sun. The gravity of Mars is roughly one-third to Earth’s gravity and it has a thin atmosphere with a pressure of 1% that of Earth. The atmosphere, water, ice and geology interact with each other to produce dynamic Martian environment as in Earth. Mars has surface features reminiscent of both the impact craters of the Moon, volcanoes, deserts and 1 polar ice of Earth. It inspires...

...With the population in the world increasing dramatically it makes clean air more difficult to find. The United States noticed back in 1970 that we were going to have a problem with pollution. This caused the US Congress to pass the Clean Air Act and amend it in 1977 and again in 1990. Scientists have found that there are eight main air pollutants, sulfur dioxide, particulates, carbon monoxide, ozone, nitrogen dioxide, lead, carbon dioxide, and hydrocarbons. These air pollutants can cause other problems such as photochemical smog, temperature inversions, and the two most harmful acid deposition and acid rain. Sulfur dioxide is one source of air pollution. This is a yellowish brown gas that forms when fuel, coal, and oil are burned. One major problem of sulfur dioxide is that is dissolves in water vapor to form acid. It interacts with other gases and particles in the air to form chemicals that can not only be harmful to humans, but the environment that surrounds them. Sulfur dioxide not only aggravates symptoms of heart and lung disease, but it also obstructs breathing passages and increases your risk of common colds, asthma, and emphysema. It is also very harmful to the world around us. It is very toxic to the plants that provide us with our air we breath. Sulfur dioxide destroys paintings, metals, and decreases visibility. Many improvements have been made to decrease sulfur dioxide, but the biggest improvement happened in 2007 when a new ultra-low sulfur diesel became available...

...December 1972, after nearly a decade of being in Vietnam, American forces decided to take a final push for victory. For 11 days and nights US Navy and Air Force bombers, led by the vulnerable B-52 flew around the clock missions, deploying over 15 thousand tons of bombs onto North Vietnam. The operation known as Linebacker II brought the communist war machine to its knees. The men and machines of Linebacker II didn’t just fly bombing missions, they ultimately flew America out of the Vietnam war. Many historians place the outcome of the Vietnam War and Linebacker II in the hands of the pilots, crews and the bombers that they flew. American bombers used in the Vietnam war For four years, the US Air Force and Navy hold and pummel the North Vietnamese...

...the macro and competitive environment of an industry. In turn this requires a reshaping of strategies for most of the individual companies in the industry in order to cope with this new environment. It also provides an opportunity for students to recommend how airlines might better plan for, as well as react to, disruptive events such as 9/11 happening in the future. ● ● ● This is a true story from the many stories of 11 September 2001. It was a typically routine early morning flight home. United flight 890 had left Narita Japan several hours earlier, and the sun would be coming up any minute. Captain Jim Hosking was looking forward to getting home to see his wife in LA. Suddenly a message from the cockpit teleprinter came in from the US Federal Aviation Authority (FAA). Such messages were routine, advising of bad weather or maintenance requirements. However, this message was different and it read: UA890 NRTLAX – –MESSAGE FROM CHIDD– THERE HAS BEEN A TERRORIST ATTACK AGAINST UAL AND AAL AIRCRAFT. WE ARE AT HIGH ALERT.

...Air Pollution Air pollution is caused by many things * the increasing number of cars on our roads * growing cities * the fast development of our economy * industrialisation Air pollution, as we know it today, started with the Industrial Revolution in Europe in the 19th century. In the last few decades, it has become the major problem for our environment. Clean air is normally made up of nitrogen (76 %) , oxygen (22%) , carbon dioxide and a few other gases. When harmful elements get into the air they may cause health problems and can also damage the environment, buildings and soil. They make the ozone layer thinner and thinner and lead to the warming of the earth’s atmosphere and climate changes. Our modern life style has led to dirtier air over the years. Factories, vehicles of all kinds, the growing number of people are some things that are responsible for air pollution today. But not all pollution in the air is caused by people. Forest fires, dust storms and volcanoeruptions can lead to the pollution of the atmosphere. Major pollutants and where they come from Carbon monoxide is a colourless gas that is set free when wood, petrol or coal are not completely burned. It is also in products like cigarettes. Because of it , less oxygen enters our blood and it makes us confused and sleepy. Carbon dioxide is a greenhouse gas that gets into the atmosphere when we burn coal , oil or wood. Chlorofluorocarbons (CFCs) are gases that come from air-conditioning systems...

...Today, I will inform you about our development site’s interactions among organisms, ecosystem services, and air quality. Our site is located on Brook Ave, across the street from various stores, train tracks, a juvenile center, and a school. Our site is run down, abandoned, and unkept. The juvenile center produces smoke from the heating placed in the building which can contaminate the air around the site. Our site has potential to have both positive and negative impacts in our community. There are many living organisms located at our site. For example, various types of plants, rodents, insects, and birds have made our site their habitat. Insects, birds, and rodents feed on the plant life available at our site. Rodents also probably feed on...

...September 11, 2001, has changed the lives of people around the world especially our military in which thousands of lives has been lost or affected by the War on Terrorism. The terrorist attack on September 11, 2001 that hit the Twin Towers of the World Trade Center in New York, the Department of Defense (Pentagon) in Arlington, Virginia, and Shanksville, Pennsylvania led to the Global War on Terrorism. The Global War on Terrorism and the invading into Iraq for weapons of mass destruction led to a major change in the military. The United States military have been fighting two wars for the last decade: Operation Enduring Freedom in Afghanistan and Operation Iraqi Freedom in Iraq. On September 11, 2001 around 8:45 Tower 1 was hit by American Airlines, Flight 11 out of Boston, Massachusetts and United Airlines, Flight 175 hit Tower 2 at exactly 9:03 which both buildings collapsed. (Giuliani 2002) The location of where the Towers collapse became to be known as Ground Zero. Over thousands of police officers, fire men, volunteers, and the National Guard patrol the streets of New York helping with the recovery. That day as a result of this evil attack on the United States about 3,500 people were killed and the lives of thousands were greatly affected. Families all over the United States changed that day. The United States were at War with Terrorism. On October 7, 2001 the United State military and other NATO Forces launched an air strike and Special Forces with ground troops attacked...

...(8pts) Is the atmospheric “greenhouse effect” bad for us and for our planet? Explain your answer. The greenhouse effect allows the sun’s radiation to get to Earth and absorbs some of the infrared radiation from Earth. Without the greenhouse effect, we would release too much infrared energy which would cause our planet to freeze. Greenhouse gases actually occur naturally and they are good for us and the planet because they are responsible for keeping the Earth warm enough to sustain life. 2. (8pts) Draw the atmosphere’s vertical temperature profile from the surface to about 75 miles high. Clearly label the different layers and the boundaries between the layers. (Be sure to properly label the axes of your graph). 3. (9pts) Discuss three different types of “apparent temperature”. (Do not give three examples of the same type of apparent temperature). For each type, explain why the “how-it-feels” temperature differs from the actual air temperature. 1. Due to the serious effects on your health that weather can have on a person, the Heat Index was developed. The heat index takes into account air temperature and relative humidity to determine the apparent temperature of what it feels like outside. This differs from the actual air temperature as it can feel hotter outside when there is less humidity in the air. 2. How the wind makes us feel can be explained by the wind chill index. When the wind blows, it moves the warm insulating air away from you and heat is rapidly lost. When the wind...

...power company produces 1100 megawatts of renewable energy as well as nuclear energy to help power our home. The main type of energy that they use for and energy source is solar energy. This is one of the most valuable types of energies around. In order to be able to use this energy, you first must use solar water heating system, so that it can absorb the suns energy. For it to do this, solar panels are placed on the roof of your home or apartment complex building, allowing it to get the power it needs to power your home. This method is more preferred to many people here in Georgia, to help get the energy they need into their homes. Hydropower is another form of energy that we use here as well. Hydropower is fuel by the water that fall from the dams. Once powered, the water is then released and begins to generate the power that is needed. The thing that makes this energy the most used energy to date is the fact that it doesn’t pollute the air and all the water that is used isn’t removed from the damn either. The energy from the turbine is transferred to a power transformer, which helps increase the voltage and then is sent to the line to distribute the power. Another energy used is biomass, this is one of the oldest forms of energy sources around. Biomass...

...only was he a brilliant naval commander he was an innovator and saw that the air power is the future of naval warfare and saw to the better aircraft for the Japanese navy. His methods to attack were unique and his opinions were always valued by those around him. Although he saw America as an enemy he respected the power and industrial might the United States held compared to Japan. He was once asked by the Japanese Prime Minister if Japan stood a chance against America. He replied, “We can run wild for six months or a year, but after that I have no confidence.” (Joseph). Yamamoto was born April 4th, 1884 and was the sixth son to Sadayoshi Takano. His name means 56 only because his father was 56 at his date of birth. At the age of 16 he joined the Japanese Imperial Navy and was sent to Japanese Naval Academy at Etajima. He graduated in 1904 and was stationed around the cruiser Nisshin and the participated in the battle for Tsushima Strait. He lost two fingers on his left hand, but because of his potential leaderships skills was sent to Naval Staff College in 1913. In 1919, Yamamoto was sent to study in America. He studied English in Harvard and also studied into the strengths and weakness of the US. He graduated in 1923 and was knowledgeable in naval aviation and viewed it as the future of naval combat. However, many believed that battleships were the key to naval combat and would ignore his ideals. Around the late 30’s because of his ideals were against the current regime Navy Minister...
