Planet formation theory

Planet formation theory Introduction Formation of the Solar System Accretion of solid bodies led to formation planetesimals protoplanets planets Planet formation is a much talked upon topic amongst scientists, although most agree with Viktor Safronovs planet formation theory. Safronov proposed the planetesimal hypothesis, which states, planets are created from dust particles which undergo collisions and stick together, eventually forming larger and larger bodies. The dust particles collide due to the gravitational forces exerted on upon the surrounding gasses by the protoplanetary disk. The protoplanetary disk is a rotating disk of matter which includes gas and dust, which surrounds newly formed stars.As the bodies increase in sizes to upwards of 1 kilometer, their own gravitational forces help them in supplementary growth into protoplanets. Another theory which tries to explain the formation of the universe was the gravitational collapse theory, which says planets form much like stars through the swift contraction of hydrogen clouds in the nebula. Although this theory provides a model of the creation of the universe, it does nt fit the available data, and cannot explain the creation of terrestrial-mass planets. 1 1 http://www.deepfly.org/TheNeighborhood/7c3-Evolution.html Terrestrial inner planets vs. Outer giant gaseous planets Our solar system consists of 8 planets, which orbit around the sun. The four inner planets are Mercury, Venus, Earth, and Mars. Theses planets are composed of heavier elements such as Iron, Silicon, Magnesium, Sulphur, and Nickel, as such they are all terrestrial planets. The four outer planets are Jupiter, Saturn, Uranus, and Neptune. They are composed of lighter elements, mostly consisting of Hydrogen and Helium. The differences between the outer gaseous planets and the inner terrestrial planets can all be explained by the theory of accretion and of the activity of the protoplanetary disc. Accretion is the process by which debris and dust are joint together through collisions due to gravitational forces within the protoplanetary disc. Findings show that gaseous components of begin to dispel soon after the star birth, and the nebula is fully depleted within just several million years. As such in many cases, accretion would take place at a greater rate than the depletion of gases, al lowing protoplanets of critical mass about 10 times that of Earth, to form within this time. Outer gas giants are formed within the ice line of the solar system where there is a high concentration of ice and gases allowing many collisions to place and as such create a planet of large critical mass. On the other hand, Terrestrial planets form much slower than gaseous planets, since they are composed in the ice line, a region which give little orbital space and mostly rocky and metallic materials. Their slow accretion rates are due to the fact that this region does not possess as much ice and gasses as the other regions. After the process of accretion, protoplanets of sizes of several hundred kilometres are formed, and these planets face many more collisions, eventually becoming Terrestrial planets. 1 1http://www.deepfly.org/TheNeighborhood/7c3-Evolution.html Formation of planetary rings Planetary rings are rings of dust, rocks, and other small particles orbiting around a planet in a flat circular motion, as seen in figure 1. These planetary rings are found in the four outer gaseous planets Jupiter, Saturn, Uranus, and Neptune. A prime example of this would be the ever famous rings of Saturn. The source of particles for these planetary rings can be traced back to the numerous collisions of Icy planetesimals which caused fragmentations and so bring forth many smaller pieces. Although the real mystery which plagues the minds of scientists, is how the material which make up these enormous rings were brought to their present position inside the gravitational radius of the planets. This process may have been different for every ring system. For instance, Jupiters rings are to be in a mature state, with balance between the loss of particles, and the production of new ones, supplied from the planets inner moons. On the other hand, scientists are divided over their beliefs o n how the rings of Saturn were formed. Some believe the rings are remnants of the protoplanetary process, whiles others believe the rings have just come into existence only several million years ago. 1 http://www.britannica.com/EBchecked/topic/553008/solar-system/242067/Formation-of-ring-systems Asteroid belt, between , Mars and Jupiter Asteroids are small irregularly shaped bodies of material composed of rocks and metals, which rotate the sun in a region between Mars and Jupiter. Asteroids are also known as Small Solar System Bodies (SSSBs), along with other irregular shaped materials such as comets. One theory suggests that asteroids are the remains of a larger protoplanet which faced a cataclysmic collision resulting in its numerous partitions, yet this theory fails to explain why there are exactly so many asteroids in the asteroid belt. Therefore scientists widely consider the following as the correct hypothesis on the creation of the asteroid belt. It is believed that asteroids are the remnants of protoplanetary matter formed by the protoplanetary disc, which can be seen by the immense number of asteroids in our solar system. Asteroids are leftover since they were within the immense gravitational radius of Jupiter, causing them to undergo destructive collisions, and even at times slinging them at a course beyon d the gravitational energies of our solar system. Therefore, no planetesimals could be formed and thus, the rocky matter remains continuously orbiting the sun.1 http://www.solstation.com/stars/asteroid.htm Formation of Earths moon We as humans need the moon. For it is the Moon`s orbit around the Earth that gives our planet a stable rotation, preventing polar shifts, which could lead to catastrophic results in global climate. Some scientists even believe the moon was a fundamental factor in the evolutionary cycle of life on earth. This is because the moon is of the main causes of Tides on Earth, and these very tides were a fundamental factor in the migration of amphibians into coastal regions, and eventually onto land. 2 Approximately 4.5 billion years ago, around the time of Earth`s formation, other protoplanetary bodies were also growing. At one point a protoplanetary body hit the Earth, sending massive amounts of debris into outer space, as seen in figure 2 (below). This debris started orbiting the Earth and eventually amassed into the moon. This theory is widely accepted since it is able to explain why the moon is not composed of an iron. The moon does not contain an iron core since, at the time of the coll ision the Earth had already depleted all of the Iron into its core, and the protoplanets iron core fused with the Earth`s core, thus only rocky matter rid of all iron was released into space. Secondly, the Earth and the moon share the same isotope composition, which can only be if the moon were formed from material from the Earth. Other theories which tried to explain the formation of the moon are the following. First, it was proposed that the Moon is a separate planetary body which formed around Earth, and went into its orbit, yet this theory failed to explain why the moon contains a core that lacks iron. Second, it was hypothesized that the moon formed elsewhere in the solar system at a place with little iron, and was gravitated into an orbit around earth, but this theory could not justify the fact that the moon`s oxygen isotope composition was the same as Earths. Third, it was proposed that the Earth had spun so fast that it spun off the moon, explaining the equivalent isotope co mposition and iron-less core, yet it failed when proper calculation were done which concluded that the moons present orbit could not take place if this hypothesis were to be correct. 2 http://www.space.com/scienceastronomy/moon_mechanics_0303018.html 1http://www.psi.edu/projects/moon/moon.html Unusual rotation of Uranus http://www.solarviews.com/eng/uranus.htm http://science.nationalgeographic.com/science/space/solar-system/uranus-article.html Concluding Paragraph

Of Mice And Men: A Critical Look At Curley?s Wife :: essays research papers

‘Of Mice and Men’, a novel by John Steinbeck, tells a story of friendship, loneliness and aspirations. Two itinerants named George and Lennie go to work on a farm as labourers in a place named Soledad. The story then ends when George takes Lennie’s life. Almost everyone on the farm is lonely and the person that represents this the most is Curley’s (the boss’s son) wife, one of the most pivotal characters in the book. When Lennie and George arrive on the farm and are shown their quarters Curley’s wife, on one of her ‘looking for Curley’ routines, sees them both and immediately starts flirting with them. George gets angry when Lennie takes a shine to her and tell him to stay away and calls her a ‘bitch’ and a ‘rat-trap’ This view is also held by many of the workers on the farm. Curley instantly takes a dislike to Lennie when he firsts meets him just because he his much considerably larger that himself. Thi s attitude towards Lennie results in him getting into a fight with him but he loses when Lennie crushes his hand with his own fist. Curley’s wife knows Lennie did this even though Curly was told to say he had caught his hand in a machine. Curley’s wife pursuit of company leads her to seek solace with Lennie. She pours out her pent up frustration of her unrealised dreams and ambitions. When she realises Lennie isn’t taking much interest she lets him feel her hair. Lennie being Lennie strokes harder and harder even though Curley’s wife begs him to stop. As she struggled to get out of his grasp he accidentally broke her neck. Lennie then ran off to his hiding place where he was told to go if he ever did a ‘bad thing.’ When Curley discovers his wife’s body he runs after Lennie with a mob including George. This leads to George pulling a trigger on Lennie. I feel Curley’s wife is the most despairing and lonely character in the book. She has no friends, no future, no respect; she doesn’t even deserve a name. I really feel sorry for her, all she wants is someone to talk to, to converse with but in her mind the only way she can do this is by flaunting herself to the men just to get noticed. This leads her to be perceived as a ‘floosy’ by the men.

Favorite Holidays Essay

1. One of my favorite Holidays is 4th of July. A few years ago my dad and I went to Washington to pick out some illegal fireworks. So we went to the Black Cat firework store . I got some mortars and roman candles and all the fun fireworks you could think of. So the day before 4th of July we were lighting off a few roman candles and all of a sudden a under cover police car pulled into our driveway and the police officer inside the car said â€Å"are you lighting off illegal fireworks?† because he saw me with the roman candles, and my dad said â€Å"yes† so the police officer confiscated all the fireworks we had bought and were fined a thousand dollars. We did get our ticket reduced down to $250 because we attended a fire works class. This definitely opened my eyes to the danger of fire works. From that day forward, I’ve learned not to do anything your not supposed to do, like buy illegal fireworks. 2. My sister graduated last year and moved to Los Angeles to pursue her passion. She grew up training in dance and singing. We have a close family and we support her all the way. My family and I traveled to see her this summer. She sang originals song and danced with her back up dancers for the music label industry. Very important people were their to see her. She did fantastic and is signing with a major record label. She will be releasing her single by the end of this year and her album in Januarary of 2014. This was a big eye opener to me to know that working hard and pursuing your dreams can really come true. 3. A couple years ago my grandmother passed away. She was very sick the last few days she was alive and my family and I knew she only had a few more days before she was to pass away. I helped her all that I could and so did my parents. She was a great grandmother and nobody could replace her, she was my dads mother, she was the best grandmother anybody could ask for. I remember the game we use to play when she would babysit me, it was called hide the thimble. She had a thumb thimble for sewing, and we use to hide it all over her house kind of like hide and seek, she also used to make the best brownies I have ever eaten. But from that day on I have always learned one thing, you never know how much you miss someone until there gone.

Quotes That Show Macbeths Intentions

The motor that drives the tragedy of Shakespeares  Macbeth  is the lead character’s ambition. It is his primary character flaw and the trait that causes this brave soldier to murder his way to power. Early on in the famous play,  King Duncan hears of Macbeth’s heroics at war and bestows the title Thane of Cawdor on him. The current Thane of Cawdor has been deemed a traitor and the king orders him to be killed.  When Macbeth is made Thane of Cawdor, he believes that the kingship is not far off in his future. He writes a letter to his wife announcing the  prophecies, and it is actually Lady Macbeth who fans the flames of ambition as the play progresses. The two conspire to kill King Duncan so that Macbeth can ascend to the throne. Despite his initial reservations about the plan, Macbeth agrees, and, sure enough, he is named king after Duncans death. Everything that follows is simply the repercussion of Macbeths unbridled ambition. Both he and Lady Macbeth are plagued by visions of their wicked deeds, which eventually drive them insane. Brave Macbeth When  Macbeth  first appears at the start of the play, he is brave, honorable, and moral—qualities that he sheds as the play develops. He comes on the scene soon after a  battle, where an injured soldier reports Macbeth’s heroic deeds and famously labels him â€Å"brave Macbeth†: For brave Macbeth—well he deserves that name—Disdaining Fortune, with his brandishd steel,Which smoked with bloody execution,Like valours minion carved out his passageTill he faced the slave.(Act 1, Scene 2) Macbeth is presented as a man of action who steps up when he is needed, and a man of kindness and love when he is away from the battlefield. His wife, Lady Macbeth, adores him for his loving nature: Yet do I fear thy nature;It is too full o th milk of human kindnessTo catch the nearest way. Thou wouldst be great,Art not without ambition, but withoutThe illness should attend it.(Act 1, Scene 5) Vaulting Ambition An encounter with the three witches changes everything. Their premonition that Macbeth â€Å"shalt be king hereafter† triggers his ambition—and leads to murderous consequences. Macbeth makes clear that ambition drives his actions, stating as early as Act 1 that his sense of ambition is â€Å"vaulting†: I have no spurTo prick the sides onlyVaulting ambition, which oerleaps itselfAnd falls on the other.(Act 1, Scene 7) When Macbeth makes plans to murder King Duncan, his moral code is still evident—but it is beginning to be corrupted by his ambition. In this quote, the reader can see Macbeth struggling with the evil he is about to commit: My thought, whose murder yet is but fantastical,Shakes so my single state of man that functionIs smotherd in surmise.(Act 1, Scene 3) Later in the same scene, he says: Why do I yield to that suggestionWhose horrid image doth unfix my hair,And make my seated heart knock at my ribs,Against the use of nature?(Act 1, Scene 3) But, as was made apparent at the beginning of the play, Macbeth is a man of action, and this vice supersedes his moral conscience. It is this trait that enables his ambitious desires. As his character develops throughout the play, action eclipses Macbeths morals. With each murder, his moral conscience is suppressed, and he never struggles with subsequent murders as much as he does with killing Duncan. By the end of the play, Macbeth kills Lady Macduff and her children without hesitation. Macbeth’s Guilt Shakespeare does not let Macbeth get off too lightly. Before long, he is plagued with guilt: Macbeth starts hallucinating;  he sees the ghost of murdered Banquo, and he hears voices: Methought I heard a voice cry Sleep no more!Macbeth does murder sleep.(Act 2, Scene 1) This quote reflects the fact that Macbeth murdered Duncan in his sleep. The voices are nothing more than Macbeth’s moral conscience seeping through, no longer able to be suppressed. Macbeth also hallucinates the murder weapons, creating one of the play’s most famous quotes: Is this a dagger which I see before me,The handle toward my hand?(Act 2, Scene 1) In the same act, Ross, Macduffs cousin, sees right through Macbeths unbridled ambition and predicts where it will lead: to Macbeth becoming  king. Gainst nature still!Thriftless ambition, that will ravin upThine own lives means! Then tis most likeThe sovereignty will fall upon Macbeth.(Act 2, Scene 4) Macbeths Fall Near the end of the play, the audience catches a glimpse of the brave soldier who appeared at the beginning. In one of Shakespeare’s most beautiful speeches, Macbeth admits that he is short on time. The armies have amassed outside the castle and there is no way he can win, but he does what any man of action would do: fight. In this speech, Macbeth realizes that time ticks on regardless and that his actions will be lost to time: Tomorrow and tomorrow and tomorrowCreeps in this petty pace from day to dayTo the last syllable of recorded timeAnd all our yesterdays have lighted foolsThe way to dusty death.(Act 5, Scene 5) Macbeth seems to realize in this speech the cost of his unchecked ambition. But it is too late: There is no reversing the consequences of his evil opportunism.

Feminism Waves Of Debates Within Feminism Essay

Gender 208 Assignment 1: Waves of Debates within Feminism Feminism, in simple terms, refers to a collective desire to end the oppression of women. Because oppression takes various forms and affects those who are victim to it in a number of different, yet often connected ways; feminism should accordingly be regarded as a multifaceted set of movements working towards multiple aims and ends. Which is to say that feminism is less a single movement concerned with the oppression of women, and more a gathering of movements concerned with a number of oppressive structures, working towards the eradication of domination period. Analysing the works of Mimi Mariuncci (2010), Audre Lorde (1984), and Rosemarie Garland-Thomson (2002) this paper will attempt to answer the question of why intersectionality is imperative to feminist discourse and Praxis, exploring the different areas in which the oppression of women interests with the oppression, marginalisation, and suppression of other minority groups, i.e. queer people, people of colour, people with disa bilities, old people, poor people, transgendered, and gender non-conforming people etc. In the pursuit of inclusivity and intersectionality feminist discourse has been tasked with acknowledging and addressing all forms of oppression as a logic of domination.

Biological Warfare Essay Research Paper Biological warfare free essay sample

Biological Warfare Essay, Research Paper Biological warfare There is no longer a inquiry of whether or non a bioterrorist will assail, but instead the inquiry remains, when will they assail? # 8220 ; It is extremely likely that a terrorist group could endanger or assail Americans with sources within the following few old ages, # 8221 ; harmonizing to President Clinton ( T.V. ) . Biological warfare deliberately uses viruses, bacteriums, Fungis, or toxins from populating beings and decease or disease in worlds, animate beings, or workss. Agitation can be used to bring forth such bacterial agents as splenic fever, undulant fever, cholera, meloidosis, pestilence, Q febrility, or tularaemia. Other viral agents are smallpox, cimean Congo HF, rift vale febrility, and vee ( Helsinsky ) . Use of these types of viruses and bacteriums are going widespread in many countries of the universe because they can impact many people expeditiously and are cost effectual. Biological arms can be traced back to Exodus when God placed the 10 plagues upon the Egyptians, as a consequence of Pharaoh # 8217 ; s refusal to liberate the Jews from bondage. We will write a custom essay sample on Biological Warfare Essay Research Paper Biological warfare or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page These pestilences included blood, toads, varmint, flies, murrain, furuncles, hail, locusts, darkness, and the murder of the first-born. Even though this type of warfare may hold had beginnings every bit early as Exodus, the procedure of doing these sources is described in scientific literature and is no secret to terrorists ( Helsinsky, other ) . Which are merely seven simple stairss to follow. The stairss are really simple, the first procedure would be to get down off by choosing a beginning of protein you want that you would desire to hold a mass sum of. The 2nd, would be to insulate and sublimate the entire RNA, after that is accumulated you would hold to do a complementary DNA utilizing the PCR. The 4th measure would be to magnify the complementary DNA by besides utilizing the PCR one time once more. Fifth, you would hold to clone the fragment by infixing the protein into a plasmid signifier and transforming an e. coli, and the concluding measure, would be to show the protein an d sublimate it. The stairss sound hard to follow, but if you know what you are making and you are familiar with the footings you can easy do a deathly arm with a chemical by following these stairss ( Helsinski ) . This source warfare is an particularly serious menace for several different grounds. The first ground is the ability of these germ agents to be undetectable to descry engineering. Second, the warfare labs that are used to bring forth these sources are hard to observe, and major states sometimes work together jointly to bring forth these agents for usage in warfare. Most significantly, it is against this menace that there may be no defence. Even though biological terrorism has been banned, it poses the greatest menace upon the Western World because of the mobility of their population. For this ground it is necessary for extremists to utilize aerosol scattering to pollute nutrient, H2O, or air ensuing in the decease of every life being. Two incidents in peculiar brand this menace of a bioterrorist onslaught more likely to happen. The first of these occurred in Tokyo when nervus gas was unleashed in a Tokyo metro by the nihilistic Nipponese cult group, Aum Shinrikyo. Twelve people were left dead and another five 1000 had to be hospitalized ( G.E. McCuen, Pg. ) . This incident raises an even greater concern because the tabu that one time prevented terrorists from assailing no longer exists ; it was broken when these warfare agents were used in the Tokyo metro. This happening opened the eyes of the universe to the demand for schemes that both prepare and prevent these types of terrorist onslaughts. The 2nd fact is that promotions in biological engineerings have become widespread throughout the universe. A lurid figure of at least 17 states are suspected of holding or trying to get germ arms. Among the 17 states is Iraq. Before the Gulf War in 1991, Iraq admitted to research and production installations and in 1995 conf essed to fabricating splenic fever spores, botulinus toxin, and aflatoxin for arms. In 1997, Sudaam Hussein # 8217 ; s forbiddance of American inspectors from look intoing their development of these arms created a widespread public concern. The universe was surprised to larn that Iraq had produced plenty lifelessly microbes to kill all the people on Earth several times over. Because certain indispensable inside informations remain unknown about honing biological arms, Iraq was neer able to get the hang their bacterial agents. On the other manus, accidental and unpredictable state of affairss can ensue from these arms of mass devastation. In Europe, the variola epidemic that occurred in the 1970 # 8217 ; s proved merely how unsafe the release of these beings could be. In 1979, when aerosolised splenic fever was released from a Russian biological arm fabrication installation, the result was proven to be a deadly accident. Another accident that is to some extent purposeful, but is turn outing to be unsafe is the island in the Aral Sea of Kazakhstan. It is at this site that Soviet soldiers buried splenic fever during the Cold War in a top-secret operation. These soldiers assumed the splenic fever would neer hold any consequence on anyone because they had soaked it in bleach with the purpose of it finally deceasing off. The Monterrey Institute of International Studies calls this island # 8220 ; a ticking clip bomb. # 8221 ; The Soviet military personnels buried the splenic fever in order to maintain the international control inspectors from detecting it. Local governments will non let the Monterrey Institute functionar ies to acquire a close adequate position of the burial site ; hence, the physical province of the inhumed splenic fever is unknown. These 66 gallon containers that originally stored this bacterium unearthed as eroding wore off at the dirt in which they lie. Animals or insect that can besides do taint, thereby, promoting the rapid spreading of the splenic fever. Because of these possible dangers, the United States should perchance see acquiring involved with the clean up attempt. America is fixing to cover with biological warfare for several different grounds. Specifically three events have forced them to do readyings. The first event was Iraq # 8217 ; s deploying of missiles that were transporting splenic fever sources. The 2nd event that is besides a menace is botulinum ( The toxin that spreads the deathly disease botulism ) . The last event that has caused America to do prepa rations is the usage of the toxicant aflatoxin that was used during the 1991 Gulf War. President Clinton wants to do the public aware to the fact that America is likely to be non merely threatened, but besides attacked with sources within the following few old ages ( other ) . He besides said that Iraq would non be permitted to bring forth these arms of mass devastation. Which were all stated a few old ages back. Surprisingly plenty, the United States supplied the natural stuffs used by Iraq to make their biological arms. Defenses are besides being strengthened and permission for the usage of about three billion dollars is being proposed to Congress in order to battle these legion assortments of biological warfare. President Clinton told authorities bureaus in June of 1995 to be prepared for onslaughts from terrorists ( other ) . But in March of 1996, the Senate brought up inquiries refering America # 8217 ; s eventuality programs and whether or non they are sufficient. Medical response is an facet that is likely the most of import concern, but oftentimes the most ign ored country for defence. This country is neglected because of the fact that it is hard to be after a response when different interventions are needed depending on the type of biological agent that is used. Philip Russell was quoted as stating: # 8220 ; Plague is different from variola, which is different from splenic fever. We need a group of folks to travel through different scenarios and believe about what could be done other than numbering the bodies. # 8221 ; Harmonizing to these statements, more competent programs are compulsory in order to protect the United States. As a consequence, scientists, public wellness functionaries, policy shapers, authoritiess, and the populace are all scrambling to happen methods of forestalling and protecting against biological warfare. The menace remains that a metropolis of five to ten million people could be wiped out prior to the following few decennaries. For these grounds, new ways are needed to forestall these onslaughts. First of all, i ntelligence plays a major function in the necessary steps that are needed. But by restricting the achievability of the starting motor civilizations used by biological terrorists, defences may be able to be strengthened. Adjunct Defense Secretary Harold Smith said that # 8220 ; Ideally we would wish to develop a sensing system utilizing something remote like a optical maser beam that could observe and place a biological agent at a draw distance. # 8221 ; After Harold Smith # 8217 ; s statement they have discovered five or six different ways to observe biological Warfare. They are known as: microscopy which is a procedure of culturing an agent or proving its effects on cells or animate beings ( Zilinskas, Pg. 86 ) , immunoassay which is happening the binding of the different antibodies linking each other to organize slayer chemicals ( Zilinskas, Pg. 87 ) , nucleic acid ( familial ) analysis is used to place the cistron sequence features of beings of involvements ( Zilinskas, Pg. 85 ) , physical and chemical method are the most normally used methods in observing a biological arm which you installation find the features and or the physical features to place the antibody ( Zilinskas, Pg. 85 ) . President Clinton made a statement refering to the bar of terrorist onslaughts. He said that # 8220 ; I would be delighted if decennaries subsequently, Americans can look back on these ( biological ) threats as the Canis familiaris that didn # 8217 ; t bark. # 8221 ; The Biological and Toxin Weapons Convention has been organized in order to battle biological warfare. This convention is working on forestalling the development, production, carrying, and build uping of these arms of mass devastation. On site inspectors are besides being suggested to help in this attempt. A convention was held in Geneva that involved diplomats and experts on weaponries control. They suggested a program that would trip biological terrorist research labs. On May 22, 1998, President Clinton announced to the United States Naval Academy # 8217 ; s graduating category that the United States is get downing to do necessary readyings in order to counter these biological onslaughts ( T.V ) . Medical, public we llness, and other countries that deal with exigency response are particularly being strengthened. In 1997, the Department of Defense proved they were taking preventative steps when they declared they were immunizing about two and a half million United States soldiers against splenic fever.
