Learn the Basics About Rocky, Dusty Planet Mars

Learn the Basics About Rocky, Dusty Planet Mars Mars is one of the most fascinating planets in the solar system. Its the subject of a much exploration, and scientists have sent dozens of spacecraft there. Human missions to this world are currently in planning and might happen in the next decade or so. It may be that the first generation of Mars explorers are already in high school, or perhaps in college. If so, its high time we learn more about this future target! The current missions to Mars include the Mars Curiosity Lander, the Mars Exploration Rover Opportunity, the Mars Express orbiter, the Mars Reconnaissance Orbiter, the Mars Orbiter Mission, and Mars MAVEN, and the ExoMars orbiter.   Basic Information about Mars So, what are the basics about this dusty desert planet?   Its about 2/3 the size of Earth, with a gravitational pull just over a third of Earths. Its day is about 40 minutes longer than ours, and its 687-day-long year is 1.8 times longer than  Earths.   Mars is a rocky, terrestrial-type planet. Its density is about 30 percent less than that of Earth (3.94 g/cm3 vs. 5.52 g/cm3). Its core is probably similar to Earths, mostly iron, with small amounts of nickel, but spacecraft mapping of its gravity field seem to indicate that its iron-rich core and mantle are a smaller portion of its volume than on Earth. Also, its smaller magnetic field than Earth, indicates a solid, rather than liquid core. Mars has evidence of past volcanic activity on its surface, making it a sleeping volcano world. It has the largest volcanic caldera in the solar system, called Olympus Mons.   Mars atmosphere is 95 percent carbon dioxide, nearly 3 percent nitrogen, and nearly 2 percent argon with trace quantities of oxygen, carbon monoxide, water vapor, ozone, and other trace gases. Future explorers will need to bring oxygen along, and then find ways to manufacture it from surface materials.   The average temperature on Mars is about -55 C or -67 F. It can range from -133 C or -207 F at the winter pole to almost 27 C or 80 F on the day side during summer. A Once-wet and Warm World The Mars we know today is largely a desert, with suspected stores of water and carbon dioxide ice under its surface. In the past it may have been a wet, warm planet, with liquid water flowing across its surface. Something happened early in its history, however, and Mars lost most of its water (and atmosphere). What wasnt lost to space froze underground. Evidence of  dried ancient lakebeds  have  been found by the  Mars Curiosity  mission, as well as other missions.  The apparently history of water on ancient Mars gives astrobiologists some idea that life might have gotten a toehold on the Red Planet, but has since died out or is holed up beneath the surface.   The first human missions to Mars will likely occur in the next two decades, depending on how the technology and planning progresses. NASA has a long-range plan to put people on Mars, and other organizations are looking into creating Martian colonies and science outposts as well. Current missions in low-Earth orbit are aimed at learning how humans will live and survive in space and on long-term missions. Mars has two tiny satellites which orbit very close to the surface, Phobos and Deimos. They could well come in for some exploration of their own as people begin their in-situ studies of the Red Planet.   Mars in the Human Mind Mars is named for the Roman god of War. It probably got this name due to its red color. The name of the month March derives from Mars. Known since prehistoric times, Mars has also been seen as a god of fertility, and in science fiction, it is a favorite site for authors to stage stories of the far future.   Edited by Carolyn Collins Petersen.

Annotated Bibliography for Journal of Economic Perspectives

Shiller, R.J., 2010. Speculative prices and popular models. The Journal of Economic Perspectives, 4(2), pp.55-65. The author provides the reader with rational expectations, especially in the economic revolution. People hold a lot of expectations for future economic variables, which influence their fundamental purchase behaviors. When prices drop, it is evident that demand in the market increases. Consumers will rush to satisfy their preferences with the affordable commodity at that time. When prices increase, demand decreases, as consumers tend to withdraw their constant purchase behaviors and only consume what is available and affordable at that time. This source highlights the rational expectations model, and the author emphasizes the importance of businesses to relate to gross oversimplification. Profitability will not increase when prices are increased, without considering the purchase ability of prospective consumers. This is a credible source, and the article goes ahead to highlight significance in understanding how the markets work, for the sake of making decisions based on speculations.

Competitive firm and the theory of input demand under price uncertainty. Journal of Political Economy, 82(3), pp.537-548. This journal article is a credible source of information. First, the behavior of the competitive business has been emphasized, as well as the problems facing the same analyzed. Making decisions under tight economic times has proven to be very difficult for most organizations.

Comp Set Analysis Research Paper Example | Topics and Well Written Essays - 500 words

Comp Set Analysis - Research Paper Example Rodeway Inn SF Civic Center enjoys a strategic location within the city. Furthermore, it offers a number of services that may enhance its competitiveness. However, the other five are equally competitive and may, therefore, threaten the hotels profitability and longevity. Crowne Plaza, for example, is a luxury hotel strategically located in the airport; the hotel poses a significant threat to Rodeway Inn SF Civic since it offers immense convenience to visitors. Additionally, Rodeway Inn SF Civic does not have conference facilities. The industry has shifted with most modern day hotels striving to attract visitors who come to the city for seminars and conferences. The lack of ballrooms and workshop facilities denies the hotel a major competitive advantage thereby making it vulnerable to the numerous competitors who are setting up shop in strategic locations within the city and continues to target the same target

Exploring the Main Characters in Five Poems of Distinct Cultures Coursework

Exploring the Main Characters in Five Poems of Distinct Cultures - Coursework Example Basically, the poem depicts the issue of color which is a common theme on the majority of literary works by Hughes and a tone that suggests racial inequality that forms through the confession of the â€Å"darker brother†. The adverb â€Å"too† signifies inclusion which connotes something missing or only part of the American population, more specifically the supreme race, are entitled to so in a way, the speaker appeals for equal rights of living with the white people of America. â€Å"I, too† presents a type of protagonist who struggles to adapt to his mistreating environment where he is often brought to â€Å"eat in the kitchen† upon the arrival of the company which could be the greater authority or the race in command. Despite such unfavorable circumstances, however, the black narrator hopes to keep up a good fight which the line â€Å"They’ll see how beautiful I am† reflects so that he may be justified to conclude â€Å"I, too, am America .† Repetition of â€Å"I† and â€Å"too† opens and closes the poem, respectively, and Hughes establishes metaphor in rendering the speaker to claim on ending with a patriotic pitch that he is America. As a Guyanese poet, on the other hand, Grace Nichols believes that Caribbean rhythms connect her sense of spirituality in Africa to all other cultures of the East and the West. This can be well recognized in her work â€Å"Praise Song for My Mother† which primarily characterizes her coastal life as applied to the maternal sentiments she uniquely identifies her mother with. Through a series of enjambment which normally appear on the beginning of each stanza under a nostalgic tone, Nichols makes her mother the central figure of the metaphors which she utilizes in comparing Caribbean attributes with the relevant traits possessed by her mother. The use of water, moon’s eye, and sunrise is elemental then the speaker, in the second-person point of view, elaborates the basic details with extended metaphors in order for the reader to understand how special and affectionate parenting is experienced during the childhood days of the poet. Essentially, Nichols likens her motherâ₠¬â„¢s care to the general life in the coast where almost all natural resources by which to sustain one’s living exist just as everything a child needs is with the loving mother’s safekeeping. Such is evident in â€Å"deep and bold and fathoming† which is quite symbolic of qualities a mother’s goodness has as well as â€Å"rise and warm and streaming† in reference to the characteristics of blood and milk all mothers share in common. With repetition of the word â€Å"replenishing† after enumeration with fishes, flamer’s tree, and crab’s leg, Nichols puts a stress on her encounter of abundance with the coast which does not occur to run out of life’s fundamental necessities just like a mother’s love and patience that altogether endures with time. â€Å"Island Man† is another piece which Grace Nichols fashions in the absence of punctuations throughout the poem’s structure. One may feel that the poetâ€⠄¢s attempt with enjambment has to do with the substance of her chosen subject which is hugely associated to Caribbean features involving seas and waves representing expanse and forms that are typically free and unbounded in nature. On this ground, thus, Nichols prefers not to punctuate in discussing

On Epictetus Discourse About Wealth and Freedom Essay

On Epictetus Discourse About Wealth and Freedom - Essay Example One thinks that wealth brings freedom and so he seeks to own gold, diamonds, lands and slaves through whatever means including what has been mentioned earlier. Another considers a high political status as something that would bring him freedom and in the modern world; education is regarded by most as the means to freedom. To Epictetus, he uses the first argument and links wealth and freedom in a manner that is debatable in an era where wealth is widely sought for, one that contradicts modern lifestyles, disagreeing that wealth brings freedom. Epictetus counts wealth as something that enslaves rather than frees someone because these are not the things that make men free rather are the ones that bound them to slavery. He considers owning nothing as having freedom, a concept that most of the people today might not agree with. One might laugh as well at such a concept, for how could a wealthy man be enslaved when he has the means to own his own slaves and be the master of other people? T he philosopher explains his arguments with examples that strongly support his thoughts, qualifying it as a serious thought one should think about not only by the seekers in his time but also in this period where it is believed to be most needed. Looking into his philosophies, one would have an illumination of his considerations and is guaranteed to be more inclined to agreeing than questioning. First, the philosopher considered fear and said that no one really fears Caesar but that they fear death, exile, deprivation of property, prison and disenfranchisement (Matheson, p. 72). Slavery to fear is not actually caused by men, not even powerful men, but is caused by what a person wants, things that he holds on to. This is the reason why Epictetus argues that having nothing, which includes wanting nothing, will release a person from fears. When an individual has properties, and is so attached to them, he would do everything he can to protect it from those who desire to have it, like rob bers. Wealth brings fear of losing it, fear of calamities, fear of people and things that would destroy and grab it away from him therefore a wealthy man is a slave to his fears, and is punished on his mind as to remedy how he should protect himself and his wealth. Sometimes, wealthy people also fear for their lives, because it is inevitable that when a person is after his wealth, he would plan to do all sorts or ways including unthinkable ones only to protect himself, including killing possible witnesses, killing the wealthy man. This is the reason why most of the rich ensure their security by paying thousands of dollars for security alarms and guards. Still, it does not give a hundred percent guarantee that they would all work for their purpose because as the rich man can be vigilant in his ways, robbers could also be more vigilant in their plans, thus, the fear continues and still is a master of the wealthy man. Money and wealth could be in a person’s possession but he cou ld still be a slave not to men but to an abstract yet gripping master called fear and what could be worse than to serve something that is within one’s self. Epictetus argues that one who is truly free is one who distinguishes what is his and what is not his, that he owns nothing but his will and to recognize that everything he has is God’s, so that if people take it away from him, he should let it be and if they leave him in peace, he should let it be and not worry much about the matter. Furthermore, the philosopher speaks about what people love, which can also serve as another master. People love wealth, the tribunate, the praetorship and the consulship (p. 72) which, in search for it, would cause a person to enslave himself to whatever matters and manners he
