The Sun and Its Features
Changes in the magnetic field of the sun affect us here on earth in a number of interesting ways. This magnetic field is caused by the flow of electrically charged ions and electrons on the sun, and if it didn't exist, the sun would be a much more boring star. The 11-year cycle of the sun's magnetic field accounts for many of the cool features of the sun: sunspots, solar flares, and aurora borealis. At the beginning of the cycle, the magnetic field is weak and there are very few sunspots; later, at the peak of the cycle, the magnetic field is strong, and there are many sunspots. Sunspots are relatively cool areas that appear as dark patches on the face of the sun. They occur where magnetic field lines are twisted below the surface. The period of time when the magnetic field is strong and there are many sunspots is called a solar maximum. The sun approached one of its solar maximums in the year 2000, and this maximum affected the conditions on earth.
For example, the aurora borealis, or "Northern Lights" we see in the sky are much brighter during a solar maximum. They are also more spread out over the sky. In normal years the northern lights can only be seen over the poles, but during a solar maximum they are visible to much of the northern United States and Europe. Aurora borealis is caused by the solar wind that blows off the corona of the sun. The temperature of the corona is so high that the gravity of the sun cannot hold on to it, so hot charged particles from the corona regularly fly off the sun at millions of miles per hour. When these particles collide with atoms in the earth's atmosphere, they excite their electrons, causing them to "jump" to a higher energy level. When electrons jump to a h...

...solar maximum), less cosmic rays strike the earth, and when it is weak (during a solar minimum), many cosmic rays strike the earth. Trees record in their rings how much carbon 14 is in the atmosphere, and during the Maunder Minimum tree rings had very high levels of Carbon 14.
Thus, there seems to be a link between the sunspot cycle and the climate of the earth, with solar minimum bringing cooler temperatures and solar maximum bringing warmer ones. This, plus the beautiful displays of northern lights, and the threatening danger of solar flares, are just three ways we are effected by the solar cycle of the sun.

In “The Warmth of Other Suns” by Isabel Wilkerson, the three main characters that the story follows face a great deal of inequality and racial prejudice in both the Jim Crow south that they left and the north that they fled to. Through their stories, as well as the excerpts from Wilkerson that serve to dispel some of the common myths and to explain some of the inequalities that others faced, one is able to make many connections between the problems that Ida Mae, George Starling, and Richard Foster, among many others, faced in their time and the obstacles to equality that our society still to this day struggles to overcome. A large reason as to why these obstacles still exist is that many have preconceived ideas about African Americans and African American Communities. However, numerous obstacles still survive to this day as a result of certain racist ideas.
During the March 1986 edition of the Journal of Modern Literature, Lee Clark Mitchell of Princeton University opens his article “‘Keeping His Head’: Repetition and Responsibility in London’s ‘To Build a Fire’” by critiquing naturalism’s style of storytelling. Mitchell claims naturalism as a slow, dull, and plain way of capturing an audience; and Jack London is the epitome of this description. Mitchell states, “[London’s] very methods of composition prompt a certain skepticism; the speed with which he wrote, his suspiciously childish plots…have all convinced readers to ignore the technical aspects of h...
I’ll Give You The Sun by Jandy Nelson is about two twins, Noah and Jude, who have a close relationship but 3 years later, they don’t even talk. Each of them shares their story about love and sacrifice. However, the twins do not realize that each of them only has half the story. In the book, the twins had to reunite in order to clear up their past. The theme in I’ll Give You The Sun is to stay true to yourself. Jandy Nelson expresses this theme through characterization, symbolism, and plot.
Macbeth is first introduced as a war hero, slayer of the Norweyans. He is then introduced to prophesy by three witches. They prophesize how he will become first Thane of Cawdor and then king. "All hail, Macbeth! hail to thee, thane of Cawdor!...Macbeth, that shalt be king hereafter." (Act 1 Scene 3). Macbeth becomes thane and starts to believe in the prophesies if the witches. What first started as inquisitiveness and doubt, soon became fate and truth as the Bible is to Christians. Macbeth began to believe the next prophesy. In fact, not only would he become king, he made it his personal obligation and responsibility to see that it became so. With a little bit of nagging (that is the best term to use) from Lady Macbeth, Macbeth chooses to fulfill his de...
The seasons are caused by the toilet of the Earth’s axis. It is also caused by the way the tilt of the earth is pointed at; away or towards the sun. The tilt of the earth is 23.5 degrees. There are two solstices, the summer solstice and the winter solstice. The summer solstice is when the northern hemisphere is focused on the tilt towards the sun, maximum sunlight is reached here. The winter solstice is when it is focused on the tilt away from the sun, there will be minimum sunlight. The winter builds up cold air over North America. The Earth is closer to the sun when it is winter in the northern hemisphere. The distance from the sun varies. The earth has seasons because the earth is not straight, it is tilted. The Earth's distance from the sun does not cause the seasons. Many people believe that the seasons are caused by Earth's orbit around the sun, but this is false. Winter occurs when the Earth is closest to the sun, while summer occurs when the Earth is farthest from the sun.

Today many patterns including real estate sales to fluctuations in the climate have been attributed to the cycle of sunspots. These fluctuations may be an explanation of the decline of Sun worship in India due the increased sunspot activity during the time of the Medieval Maximum. Throughtout history these fluctuations have been omens (e.g. a slave revolutionists incited a riot when he interpreted the site of a large black area on the Sun as the black taking over the white) (Schaefer 38). There are also modern examples of solar fluctuations affecting the Earth like the delayed launch of the Hubble Telescope (Schaefer 38) and the disruptions in electrical and radio technology during solar flares due to increased activity of sunspots at the last solar maximum in 1989.
Throughout history climates have drastically changed. There have been shifts from warm climates to the Ice Ages (Cunningham & Cunningham, 2009, p.204). Evidence suggests there have been at least a dozen abrupt climate changes throughout the history of the earth. There are a few suspected reasons for these past climate changes. One reason may be that asteroids hitting the earth and volcanic eruptions caused some of them. A further assumption is that 22-year solar magnetic cycles and 11-year sunspot cycles played a part in the changes. A further possibility is that a regular shifting in the angle of the moon orbiting earth causing changing tides and atmospheric circulation affects the global climate (Cunningham & Cunningham, 2009, p.205). Scientific studies suggest that all these played a role in past global warming and cooling periods. Today, however, there is a lot of conflict on whether humans are causing a global warming that could be disastrous to humans and all species of plants and animals on this earth. This paper will first explain the greenhouse effect, then take a look at both sides argument, and, finally, analyze the effect of global warming on world-wide sustainability
Abraham Maslow wrote the Maslow’s hierarchy of needs theory. This theory was based on fulfilling five basic needs: physiological, safety, social, esteem and self-actualization. Maslow believed that these needs could create internal pressures that could influence the behavior of a person. (Robbins, p.204)
Abraham H. Maslow developed the Hierarchy of Needs model between 1943-54 in USA, and this theory remains valid even today for understanding human motivation, management training and personal development. (4) A. H. Maslow first introduced his idea of hierarchy of needs in his paper “A Theory of Human Motivation” and his succeeding book Motivation and Personality in 1943. He stated that people are motivated to achieve certain needs and they are intended to fulfil basic needs before moving on to other, more advanced needs and when one need is fulfilled they move on the next one, and so on. Maslow’s Hierarchy of Needs includes five motivational needs, often displayed as a hierarchical pyramid with five levels. This five level model can be divided into basic needs or deficiency needs and growth needs. The four lower levels are considered basic needs and the top level is considered growth needs. The five different level of hierarchy of needs are:
When looking at the Earth, it becomes readily apparent that cycles are an important theme. Earth is a closed system. Meaning only energy can pass into and out of its atmosphere with the exception with few meteorites that enter and the manmade objects we eject. Earth has the water cycle, the carbon cycle, the nitrogen cycle, the rock cycles and Earth itself cycles around the sun. It is easily understandable then that Earth climate also undergone many cyclic changes from one extreme to another within its vast history. In this paper, the focus in on the climate events that occurred from 65 Ma to present day Earth (Cenozoic era), some ways in which this information about climate can be collected and possible implications for the future

When a solar flare occurs, vast amount of magnetic energy get released and turned into electromagnetic radiation. (NASA 2015) Traveling at light-speed, the resulting radiation containing X-ray, extreme ultraviolet rays, gamma rays and radio waves would arrive at Earth after only 8 minutes. The x-rays may interact with the atoms in the ionosphere of Earth and cause a sudden increase in ionization, which could interfere radar and shortwave radio communication. The ultraviolet rays can heat the upper atmosphere, causing the atmosphere shell to expand, which may drag low orbiting satellites and spacecraft, leading to unexpected orbital changes (Marusek 2007). For instance, the premature demise of the Solar Maximum Mission in 1990 and Skylab in 1979 are due to this phenomenon (Odenwald
