Dwarf Planet Haumea and the Outer Solar System

Theres an odd little world in the outer solar system called 136108 Haumea, or Haumea (for short). It orbits the Sun as part of the Kuiper Belt, far beyond the orbit of Neptune and in the same general region as Pluto. Planet searchers have been observing that region for years now, looking for other worlds. It turns out there are many of them out there, but none have been found — yet — as weird as Haumea. Its less like a sedately orbiting planet and more like a wildly spinning top. It lopes around the Sun once every 285 years, whirling madly, end over end. That motion tells planetary scientists that Haumea was sent into that propeller-like orbit by a collision with another body sometime in the past. Stats For a tiny world out in the middle of nowhere, Haumea presents some striking statistics. Its not very big and its shape is oblong, like a fat cigar that is 1920 kilometers long, about 1,500 km wide and 990 kilometers thick. It spins on its axis once every four hours. Its mass is about a third of Plutos, and planetary scientists classify it as a dwarf planet — similar to Pluto. Its more properly listed as a plutoid due to its ice-rock composition and its position in the solar system in the same region as Pluto. It has been observed for decades, although not recognized as a world until its official discovery in 2004 and the announcement in 2005. Mike Brown, of CalTech, was set to announce his teams discovery when they were beaten to the punch by a Spanish team who claimed to have seen it first. However, the Spanish team apparently accessed Browns observing logs just before Brown was set to make his announcement, and they claim to have discovered Haumea first.   The IAU credited the observatory in Spain for the discovery, but not the Spanish team. Brown was given the right to name Haumea and its moons (which is team discovered later).   Collision Family   The fast spinning motion that flips Haumea around as it orbits the Sun is the result of a long-ago collision between at least two objects. Its actually a member of whats called a collisional family which contains objects all created in an impact that took place very early in the solar systems history. The impact shattered the colliding objects and might also have removed much of primordial Haumeas ice, leaving it a largely rocky body with a thin layer of ice. Some measurements indicate that theres water ice on the surface. It appears to be fresh ice, meaning it was deposited within the past 100 million years or so. Ices in the outer solar system are darkened by ultraviolet bombardment, so fresh ice on Haumea implies some kind of activity. However, no one is sure what that would be. More studies are needed to understand this spinning world and its bright surface. Moons and Possible Rings Small as Haumea is, its large enough to have moons (satellites that orbit around it). Astronomers spotted two of them, called 136108 Haumea I Hiiaka and 136108 Hamuea II Namaka. They were found in 2005 by Mike Brown and his team using the Keck Observatory on Maunakea in Hawaii. Hiiaka is the outermost of the two moons and is only 310 kilometers across. It appears to have an icy surface and it might be a fragment of the original Haumea. The other moon, Namaka, orbits closer to Haumea. Its only about 170 kilometers across. Hiiaka orbits Haumea in 49 days, while Namaka takes only 18 days to go once around its parent body. In addition to the small moons, Haumea is thought to have at least one ring surrounding it. No observations have conclusively confirmed this, but eventually astronomers should be able to detect traces of it.   Etymology Astronomer who discover objects get the pleasure of naming them, according to guidelines set up by the International Astronomical Union. In the case of these distant worlds, the IAUs rules suggest that objects in the Kuiper Belt and beyond should be named after mythological beings associated with creation. So, the Brown team went to Hawaiian mythology and selected Haumea, who is the goddess of the island of Hawaii (from where the object was discovered using the Keck telescope). The moons are named after Haumeas daughters. Further Exploration   Its not too likely that a spacecraft would be sent to Haumea in the near future, so planetary scientists will continue to study it using ground-based telescopes and space-based observatories such as Hubble Space Telescope. There have been some preliminary studies aimed at developing a mission to this distant world. It would take a mission nearly 15 years to arrive there. One idea is to have it settle into orbit around Haumea and send back high-resolution images and data. So far, there are no concrete plans for a Haumea mission, although it would certainly be an interesting world to study up-close!

Patient-Centered Care free essay sample

In a culture as diverse as the United States it is of great importance that individuals in the health care field learn to communicate and understand each patient. We must remember when implementing a communication strategy, that there are many elements that affect the experience: cultural variations, personal dignity, and interpersonal relationships. Gathering knowledge of patient’s beliefs, and values, along with community preferences can be an effective strategy to overcoming diversity and improving communication. It is important to understand not only that people are different but also how to embrace these differences in order to supply individuals with appropriate healthcare. This is a teaching strategy about a couple who thought they were doing the best for their first born child but in return was possibly going to lose them forever. There were decisions that they were going to have to make, whether to continue with the treatment or stop it.

Battle of Ridgefield in the American Revolution

Battle of Ridgefield in the American Revolution Battle of Ridgefield - Conflict Date: The Battle of Ridgefield was fought April 27, 1777, during the American Revolution (1775-1783). Armies Commanders Americans Major General David WoosterBrigadier General Benedict Arnold700 rising to 1,000 menBritishMajor General William Tryon1,800 men Battle of Ridgefield - Background: In 1777, General Sir William Howe, commanding British forces in North America, commenced planning operations designed to capture the American capital at Philadelphia.   These called for him to embark the bulk of his army in New York City and sail to  the Chesapeake Bay  where he would strike his target from the south.   In preparing for his absence, he  provided the  Royal  Governor of New York, William Tryon, with a local commission as a major general and directed him  to harass American forces in the Hudson Valley and Connecticut.   Early that spring, Howe learned through his intelligence network of the existence of a large Continental Army depot at Danbury, CT.   An inviting target, he instructed Tryon to  put together a  raid to  destroy it. Battle of Ridgefield - Tryon Prepares: To accomplish this objective, Tryon assembled a fleet of twelve transports, a hospital ship, and several smaller vessels.   Overseen by Captain Henry Duncan, the fleet was to transport the 1,800 men of the landing force up the coast to Compo Point (in present-day Westport).  Ã‚  This command drew troops from 4th, 15th, 23rd, 27th, 44th, and 64th Regiments of Foot as well as contained a group of 300 Loyalists  taken from  the Prince of Wales American Regiment.   Departing on April 22, Tyron and Duncan  spent three days working their way up the coast.   Anchoring in the  Saugatuck River,  the British advanced eight miles inland before making camp. Battle of Ridgefield - Striking Danbury: Pushing north the next day, Tryons men reached Danbury and  found Colonel Joseph P. Cookes small garrison attempting to remove the supplies to safety.   Attacking, the British drove off Cookes men after a brief skirmish.   Securing the depot, Tryon directed  its contents, largely foodstuffs, uniforms, and equipment, to be burned.   Remaining in Danbury through the day, the British continued the destruction of the depot.  Ã‚  Around 1:00 AM on the night April 27, Tryon received word that American forces were approaching the town.   Rather than risk being cut off from the coast, he ordered the houses of Patriot supporters burned and made preparations to depart. Battle of Ridgefield - The Americans Respond: On April 26, as Duncans ships passed Norwalk, word  of the enemys approach reached  Major General David Wooster of the Connecticut militia and Continental Brigadier General Benedict Arnold at New Haven.   Raising the local militia, Wooster ordered it to proceed to Fairfield.   Following, he and Arnold arrived to find that the commander of the Fairfield County militia, Brigadier General Gold Silliman, had raised his men and moved north to Redding leaving orders that newly-arrived troops should join him there.   Uniting with Silliman,  the combined American force numbered 500 militia and 100 Continental regulars.   Advancing towards Danbury, the column was slowed by heavy rain and around 11:00 PM halted at nearby Bethel to rest and dry their powder.   To the west, word of Tryons  presence reached Brigadier General Alexander McDougall who began assembling Continental troops around Peekskill. Battle of Ridgefield - A Running Fight: Around dawn, Tryon departed Danbury and moved south with the intention of reaching the coast via Ridgefield.   In an effort to slow the British and allow additional American forces to arrive, Wooster and Arnold split their force with the latter taking 400 men directly to Ridgefield while the former harassed the enemys rear.   Unaware of Woosters pursuit, Tryon paused for breakfast approximately three miles north of Ridgefield.   A veteran of the 1745 Siege of Louisbourg, the French Indian War, and the American Revolutions Canadian  Campaign, the experienced Wooster struck and successfully surprised the British rearguard, killing two and capturing forty.   Quickly withdrawing, Wooster  attacked again an hour later.  Ã‚  Better prepared for action,  British artillery repelled the Americans and Wooster fell mortally wounded. As fighting commenced north of Ridgefield, Arnold and his men worked to build barricades in the town and blockaded the streets.   Around noon, Tryon advanced on the town and commenced an artillery bombardment of the American positions.   Hoping to flank the barricades, he then sent forward troops on either side of the town.   Having anticipated this, Silliman had deployed his men in blocking positions.   With his initial efforts halted, Tryon made use of his numerical advantage and attacked on both flanks as well as pushed 600 men  directly against the barricade.   Supported by artillery fire, the British succeeded in turning Arnolds flank and  running battle ensued as  the Americans withdrew  down Town Street.   In the course of the fighting, Arnold was nearly captured when his horse was killed, briefly pinning  him between the lines. Battle of Ridgefield - Back to the Coast: Having driven off the defenders, Tyrons column camped for the night south of town.   During this time, Arnold and Silliman regrouped their men and received reinforcements in the form of additional New York and Connecticut militia as well as a company of Continental artillery under Colonel John Lamb.   The next day, while Arnold established a blocking position on Compo Hill that overlooked the roads leading to the landing beach, militia forces conducted an intense harassment of the British column similar to that faced during the British withdraw from Concord in 1775.   Moving south, Tryon crossed the Saugatuck above Arnolds position forcing the American commander to join the militia in  pursuit. Reaching the coast, Tryon was met by reinforcements from the fleet.   Arnold attempted an attack with the support of Lambs guns, but was pushed back by a British bayonet charge.   Losing another horse, he was unable to rally and reform his men to make another assault.   Having held, Tryon  re-embarked his men and departed for New York City. Battle of Ridgefield - Aftermath: The fighting at the Battle of Ridgefield and supporting actions saw the Americans lose 20 killed and  40 to 80 wounded, while Tryons command reported casualties of 26 killed, 117 wounded, and 29 missing.   Though the raid on Danbury achieved its objectives, the resistance faced during the return to the coast caused concern.   As a result, future raiding operations in Connecticut were limited to the coast including an attack by Tryon in 1779 and one by Arnold after his betrayal that resulted in the 1781 Battle of Groton Heights.  Ã‚  In addition, Tryons actions led to an increase in support for the Patriot cause in Connecticut including an upswing in enlistments.   Newly-raised troops from the  colony would aid Major General Horatio Gates later that year in the victory at Saratoga.   In recognition  for his contributions  during the Battle of Ridgefield, Arnold received  his much-delayed promotion to major general  as well as a new horse.

Introduce, Discuss, and Analyze The Ethics of Selling Organs essays

Introduce, Discuss, and Analyze The Ethics of Selling Organs essays The purpose of this paper is to introduce, discuss, and analyze the essays "The Body Bazaar" by Karen Wright and "'Strip-Mining' the Dead: When Human Organs Are for Sale" by Gilbert Meilaender. Specifically, it will compare and contrast the writers' perspectives on selling and transplanting body organs. The moral and ethical issues surrounding human organ transplant and sale are many, and many of them are ingrained with society's fear of death, dying, and money. Some people feel it is incomprehensible to even think about selling or donating a loved ones organs after death, but there are thousands of transplant patients waiting for organs or they will die and there lies the moral dilemma. Families of transplant patients waiting desperately for transplants so they can survive are always emotional and heart wrenching. Equally moving are the stories of families who donate their loved ones vital organs after a tragic accident trying to find some meaning in their loved ones' untimely deaths. Yet millions of transplant victims are still on waiting lists every year, and many people simply would not consider donating an organ, no matter how drastic the need. These two authors discuss the ethics and morality of donating organs, but they also discuss another aspect of organ transplant, the sale of donor organs for profit, something that most people are much more squeamish about even considering. Author Meilaender notes, "It's not hard to understand our national reluctance to permit the buying and selling of human organs for transplant, for it expresses a repugnance that is deeply rooted in important moral sentiments" (Meilaender). In contrast, Wright's essay at first dis cusses body part harvesting as a business just like any other. She writes, "Core-blood banking is just one of many enterprises that make up the late-twentieth-century trade in body parts and products" (Wright,?, p. 476). Clearly, this is the same issue, but vi...

Philosophy High School Essay Example | Topics and Well Written Essays - 1500 words

Philosophy High School - Essay Example This is usually translated as the Way. But it's hard to say exactly what this means. The Tao is the ultimate creative principle of the universe. All things are unified and connected in The Tao. Taoism is a religion of unity and opposites; Yin and Yang. The principle of Yin Yang sees the world as filled with complementary forces - action and non-action, light and dark, hot and cold, and so on.3 The common view of Daoism is that it encourages people to live with detachment and calm, resting in non-action and smiling at the vicissitudes of the world. Contrary to this common view, Daoists through the ages have developed various forms of community and proposed numerous sets of behavioral guidelines and texts on ethical considerations. Beyond the ancient philosophers, who are well-known for the moral dimension of their teachings, religious Daoist rules cover both ethics, i.e., the personal values of the individual, and morality, i.e., the communal norms and social values of the organization. They range from basic moral rules against killing, stealing, lying, and sexual misconduct through suggestions for altruistic thinking and models of social interaction to behavioral details on how to bow, eat, and wash, as well as to the unfolding of universal ethics that teach people to think like the Dao itself. About eighty texts in the Daoist canon and its supplements describe such guide lines and present the ethical and communal principles of the Daoist religion. They document just to what degree Daoist realization is based on how one lives one's life in interaction with the community-family, religious group, monastery, state, and cosmos. Ethics and morality, as well as the creation of community, emerge as central in the Daoist religion. Livia Kohn, Cosmos and Community Taoist ethics are concerned less with doing good acts than becoming a good person who lives in harmony with all things and people.4 Taoist ethics are inseparable from Taoist spirituality - both contain the same ideas. If a Taoist wants to live well they should take all their decisions in the context of the Tao, trying to see what will fit best with the natural order of things. Taoists thus always do what is required by events and their context, but they only do what is required, no more. But what is required may be a lot less than modern Westerners think: From the perspective of classical Taoism, Western humanism makes the mistake of assuming that the ability to intervene in life's events translates into a moral duty to do so. The constant and unmistakable teaching of the Tao Te Ching is that humans are indeed capable of intervening in life's events, but the evidence of life, which humans constantly ignore, is that such intervention is destructive to all involved, and that we therefore have a moral duty to refrain from taking such actions. Russell Kirkland, Responsible non-action in a natural world So, in theory at least, Taoists tend not to initiate action - but wait for events to make action necessary - and avoid letting their own desires and compulsions push them into doing things. In practice Taoism recommends the same sorts of moral behavior to its followers as other religions. It disapproves of killing, stealing
