Have you ever thought about going on a vacation? Would you go to Alaska, the northern part of Canada, or the southern half of Sweden? I want to see Alaska, not visit because I feel I would freeze to death my first day there. Better bring a heavy wool jacket if you go to Siberia or south Antarctica. When the forecast is just right in those areas, and you go on vacation you will be able to catch a beautiful aurora. I am not talking about the Roman Goddess of dawn, although she might help with lighting up the night sky where Aurora Borealis, or Aurora Australis shine (Eos). Aurora Borealis in Latin means “red dawn of the north,” (Fast & Thomas). Internationally known as the Northern Lights. With a fascinating history, incredible views, and interesting …show more content…
One site said it was Galileo in 1619 while others quote it was a “French scientist named Pierre Gassendi in 1621,”. Still it was the lifework of the Norwegian scientist Kristian Birkeland, whose theories about the Northern Lights, electromagnetism, comets, and the sun that were accepted by the scientific community after his death in 1917 (Bookshelf). He was the first to offer the correct explanation about the Northern Lights. Birkeland studied, measured, and recorded the phenomenon is many locations and in the most different terrains, like Norway’s icy mountains and Africa’s deserts (Maxwell). It was in the Arctic where he aided Samuel Eyde in establishing magnetic observations that he determined that that Aurora Borealis was linked to the solar magnetic activity …show more content…
The Eskimo, or member of an indigenous people in northern Canada and parts of Greenland and Alaska, better known as the Inuit, belief is almost the same. They believe the Auroras are torches held in the hands of Spirits to guide the souls of those who recently departed from life to a land of happiness (Goldman). They say the swishing sound that accompanies the lights is the sound of the dead trying to communicate with those living on Earth (Goldman). With that beautiful saying, I would rather believe that then what Mrs. Bush was trying to prove in 1995. When one Anita Bush, a woman with a PH.D in neuroscience, visited the university of Alaska, she came up with a theory. Bush tried to prove that Alaska 's high rate of suicides, homicides, and accidental deaths were at fault of the geomagnetic storms caused by the Aurora Borealis (Howard). Who was at fault the person who died or the one committing the crime is a question that still has no answer. Yet, Mrs. Bush did not stop the blame there. She stated that the "lighting rod" for the lights is Alaska 's oil pipeline, which is intensifying the effect and that was the explanation of the '89 Exxon Valdez oil spill (Howard). This was a woman set on putting the blame in Alaska. Yet Mr. Irion quoted, “but when the Sun gets angry, the northern lights can signal potentially disabling

In 1895, Professor Wilhelm C. Roentgen, a German physicist, was working with a cathode ray tube, much like our fluorescent light bulb. The tube consisted of positive and negative electrodes encapsulated in a glass envelope. On November 8, 1895, Roentgen was conducting experiments in his lab on the effects of cathode rays. He evacuated all the air from the tube and passed a high electric voltage through it after filling it with a special gas. When he did this, the tube began to give off a fluorescent glow. Roentgen then shielded the tube with heavy black paper and discovered a green colored fluorescent light could be seen coming from a screen located a few feet away from the tube.
The process of photosynthesis is present in both prokaryotic and eukaryotic cells and is the process in which cells transform energy in the form of light from the sun into chemical energy in the form of organic compounds and gaseous oxygen (See Equation Below). In photosynthesis, water is oxidized to gaseous oxygen and carbon dioxide is reduced to glucose. Furthermore, photosynthesis is an anabolic process, or in other words is a metabolism that is associated with the construction of large molecules such as glucose. The process of photosynthesis occurs in two steps: light reactions and the Calvin cycle. The light reactions of photosynthesis take place in the thylakoid membrane and use the energy from the sun to produce ATP and NADPH2. The Calvin cycle takes place in the stroma of the chloroplast and consumes ATP and NADPH2 to reduce carbon dioxide to a sugar.
In Bright Star, Keats utilises a mixture of the Shakespearean and Petrarchan sonnet forms to vividly portray his thoughts on the conflict between his longing to be immortal like the steadfast star, and his longing to be together with his love. The contrast between the loneliness of forever and the intenseness of the temporary are presented in the rich natural imagery and sensuous descriptions of his true wishes with Fanny Brawne.
The first record of the movement of the planets was produced by Nicolaus Copernicus. He proposed that the earth was the center of everything, which the term is called geocentric. Kepler challenged the theory that the sun was the center of the earth and proposed that the sun was the center of everything; this term is referred to as heliocentric. Kepler’s heliocentric theory was accepted by most people and is accepted in today’s society. One of Kepler’s friends was a famous person named Galileo. Galileo is known for improving the design and the magnification of the telescope. With improvement of the telescope Galileo could describe the craters of the moon and the moons of Jupiter. Galileo also created the number for acceleration of all free falling objects as 9.8 meters per second. Galileo’s and Kepler’s theories were not approved by all people. Their theories contradicted verses in the bible, so the protestant church was extremely skeptical of both Galileo and Kepler’s
Johannes Kepler was a German astronomer and mathematician ho discovered that planetary motion is elliptical. Early in his life, Kepler wanted to prove that the universe obeyed Platonistic mathematical relationships, such as the planetary orbits were circular and at distances from the sun proportional to the Platonic solids (see paragraph below). However, when his friend the astronomer Tycho Brahe died, he gave Kepler his immense collection of astronomical observations. After years of studying these observations, Kepler realized that his previous thought about planetary motion were wrong, and he came up with his three laws of planetary motion. Unfortunately, he did not have a unifying theory for these laws. This had to until Newton formulated his laws of gravity and motion.
Climate change, or global warming, is a major issue affecting many species around the globe. Climate change can be caused by burning fossil fuels, breeding cattle that create methane, cutting down forests which absorb carbon dioxide, and the extra carbon dioxide in the atmosphere trapping the sunlight. These factors warm up the earth, and in the past century the earth has warmed by an average of about 1°. This doesn’t sound like much however on a global scale it’s huge and scientists predict a rise of up to 6°C in this century if greenhouse gasses are not cut drastically. Climate change is not just about the arctic sea ice melting, there are many other implications such as, severe storms, floods, and droughts; the sea becoming more acidic; rainforests dying, and drastic rise in sea levels. There are current strategies in place which are tackling climate change in general such as renewable energy and low carbon transport however there are also management strategies that are specific to species directly affected by climate change. When considering the species affected, many will think of the obvious species such as the polar bear and species living in cold habitats with snow and ice. This essay will address the impacts of climate change on an obvious species, the snow leopard, and a not so obvious species, sea turtles, and evaluate whether the current management of these species will be adequate to protect them in the future. It will also discuss alternative or additional management options that might help these species persist under a changing climate.
Northern Lights deals with the forces of love, betrayal, religion and science; all of these themes spur from one source, power. Each character in the novel experiences these topics, because each character is powerful. Northern Lights shows us that all individuals must either choose to use or be overcome these forces.
Ernest Rutherford’s Cavendish Laboratory at Cambridge University. Their experiment proves Albert Einstein’s theory of relativity.
When I was young and saw the picture like the figure1, I think it was not real. It cannot happen in the earth. Maybe someone did Photoshop to edit and retouch the colorful colors in that picture. However, it is a natural phenomenon that happened in the earth 's atmosphere. Galileo Galilei named this phenomenon as "Aurora Borealis." I have three areas of information about auroras to advise you: what aurora borealis is, where the aurora borealis typically seen is, and comparison and contrast this information with Witch Child.
A polar bear is a one of the eight species. “Scientists believe that the polar bear began over 200,000 years ago. They came from the brown bears ancestors.” Most experts think that polar bears are the longest bears. Males measure over 10 feet long, when standing on their hind legs, other bear not so much. Brown bears and polar bear are the largest and are both land carnivores. Polar bears are one of the worlds largest world predictors.
The research that established Faraday as the foremost experimental scientist of his day was, however, in the fields of electricity and magnetism. In 1821 he plotted the magnetic field around a conductor carrying an electric current; the existence of the magnetic field had first been observed by the Danish physicist Hans Christian Oersted in 1819.
The first time we know about magnets was in 1269, when a soldier named Peter Peregrinus, wrote a letter about everything that was known at that time about a stone called magnetite. It is reported that he was writing this when he was guarding the walls of Lucera, a small town in Italy. It is also reported that, “While people insi...
The detriment of air pollution is that it has far reaching consequences and most often is misplaced long distances by the wind. Polluted air shows up in places where you wouldn’t expect or desire it, like in the most remote parts of beloved national parks or barren wilderness. This can be attributed to higher power plant pipes that transport pollutants above a local community contribute to carrying pollutants sometimes thousands of miles away by wind. This can be particularly true in downwind states, where emissions from industrial boilers and power plants contribute to smog, haze, and air pollution hundreds of miles away (EPA, 2014) . The Clean Air Act has a number of programs designed to reduce downwind transport of pollution from one area
A solar storm refers to space weather involving solar activities like solar flares and coronal mass ejection. Although most solar storms may only have minor effect on the Earth, a particularly strong one like the 1859 Carrington Event is likely to cause damage of spacecraft and satellites, as well as radio and electricity blackout of large regions on the Earth. In the age that people’s lives are greatly dependent on electronic and telecommunication technologies, our modern civilization is under a constant threat posed by a hazardous solar storm. This paper will examine a few past solar storm observations and attempt to analyze the effects of the major components of solar storms on human technologies and people’s lives.
