.... rolls his eyes back, and rubs his temples. He replies, "Big or small?" The student baffled by this, prompts again, "Um, physics?" The teacher noticing the ignorance in the room explains, "Physics is split into two major fields: Relativity (Einstein) and Quantum. Thus, they explain big forces in nature and small forces in nature, respectively. They are not cross- applicable." The student, still baffled, persisted, "But if physics explains nature, how is it that nature can be prejudiced in what applies? I mean, why can't you just plug in numbers into equations and get the right answe .....

.... the Sherman glacier, during the big slide several other smaller slides happened and those were the one that took lives in Anchorage, and destroyed property There are a couple of types of avalanches and how the destroy so much this one is named "Loose Snow Avalanches"1, it starts' in a small area then grows in size and mass as it descends.Another type is the "Slab Avalanche" it actually starts in a large area of ice and snow and then begins to slide. On September 12 of 1717 crusaded down the Troilet, Italy glacier, gaining speed on a cushion of air reaching a falling velocity of km/hr over .....

.... the Theban (about AD 250-300) discovered that sulfuric acid is a solvent of metals, and he liberated oxygen from the red oxide of mercury. The fundamental concept of stemmed from the Aristotelian doctrine that all things tend to reach perfection. Because other metals were thought to be less "perfect" than gold, it was reasonable to assume that nature formed gold out of other metals deep within the earth and that with sufficient skill and diligence an artisan could duplicate this process in the workshop. Efforts toward this goal were empirical and practical at first, but by the 4th centu .....

.... If we cannot stop the effects, I would atleast like to know something’s I can do to lessen the effects on our environment. What is acid rain? Acid rain is the name commonly given to the deposition of a cocktail of acidifying compounds to soils, surface waters and buildings. These compounds arise mainly from the combustion of fossil fuels. In some parts of the United Kingdom, natural ecosystems have a significant acid-neutralizing capacity and acid rain has little impact on them. In other parts, the neutralizing capacity is limited, and terrestrial and aquatic ecosystems are sensit .....

.... sulphuric acid falls onto the earth as rain. All the nutrients in the soils are washed away making it hard for some plants to grow. The presence of nitrogen oxide and nitric oxide also can force trees to grow even though they do not have the necessary nutrients. The trees are sometimes forced to grow during late autumn when it is actually the time for them to prepare for severe winter weather. One of the direct effects of acid rain is on lakes and the whole aquatic ecosystems. There are several ways the acidic chemicals can enter the lakes. Some exists as dry particles in the air wh .....

.... Some others are restricted supply of suitable water, lack of suitable soil, high labor cost of traditional cultivation, high cost of sterilizing soil, and there is a greater reliability and predictability of plant production. In addition, It's easy! Depending on what is being grown, most of the time hydroponic plants require less attention than soil-grown crops. Because of this, it can relieve some people of the added responsibility that soil-grown plants require. As one can see, there are many advantages to this system of growing plants. Since its origination, thousands of companies .....

.... results. He observed that lipophilic molecules (molecules attracted to fat solvents) could easily cross this cell membrane, however larger lipid insoluble molecules could not. He also observed that small polar molecules could slowly cross the membrane. Other experiments with the likes of hen eggs suggested the presence of a lipid layer in the membrane. These results became known to biologists across the world and it was generally accepted that a semi-permeable lipid membrane surrounded some if not all cells (2). Although this was opening new doors for cell biologists, the information was w .....

.... reasoning dysfunction. Also mild language impairments begin to surface. In the moderate stage, language deficits such as aphasia and apraxia become prominent. Dysfluency, paraphasias, and bizzare word combinations are common midstage speech defects. In the severe stage the patient is gradually reduced to a vegetative state. Speech becomes nonfluent, repetitive, and largely non-communicative. Auditory comprehension is exceedingly limited, with many patients displaying partial or complete mutism. Late in the course of the disease many neuropsychological functions can no longer be .....

.... and lows, this does not seem to be a mere coincidence. Carbon dioxide currently accounts for 0.03% of the gas content within the atmosphere. However, it has a adverse impact on the earth's temperature. Thus, minor fluctuations in the percentage of atmospheric carbon dioxide will likely have a significant effect on the global temperature. The percentage of atmospheric carbon dioxide has risen over the past century at an alarming rate. Industrial civilization is essentially driven by fossil fuels such as coal, oil, and gasoline all of these are a major factor in carbon dioxide emissions. .....

.... and later coal and oil, fed the growing fires of the Industrial Revolution. The carbon stored in these fuels was released to the air as carbon dioxide - a gas that traps heat in the atmosphere. Today, for every one of the more than 5.8 billion people on Earth, nearly six tons of carbon dioxide is spewed into the air every year. As a result of our activities, the gas trapped inside the atmosphere has risen by more than 30 percent in the last 250 years. These greenhouse gases which prevent infrared radiation from escaping into space, keep the earth's temperature warm. According to th .....
