Metal Detectors In Airports Engineering Essay Essay Example Metal Detectors In Airports Engineering Essay Essay Metal Detectors In Airports Engineering Essay Essay As we all know, airport security has persistently improved. With out safely airdromes ca nt be operate. On the other side, riders would be afarid to wing becauce of fright it can has a bad consequence of air hose. Typically, air hoses lease private companies to maintain airdromes safe by some devices such as: walk trough metal sensor, X beam and so on. Metallic sensors are prevalently used to detect metal objects like for illustration: arms and stab that riders can non take it to shave. This device besides used in some edifice which security is a concern. This study is include the chief points of: investigation about the airdrome and the engineerings that they use. Then in scenario we ll hold how this engineering is extremely functional. definition of metal sensor. In add-on, we will establish out that some advantages and disadvantages that emerge of this engineering. Then, we will discourse about similarities and differences between Human Aspect, Ethical, Enterprise Computing with t he subject above. Finally, in the recommendation portion, we ll disscus about what we need to make to better this engineering. Introduction I feel it s necessary to clear up that nil is more of import than being safe. It s average, unmistakeable illegal act is increase more and more each twenty-four hours. So, we need to halt it but unluckily it s non easy and felons are adept on their work. Consequently, we should heighten our engineerings and inventions. on the other side, we should believe about the ways that can cut down offenses because it is about imposible to acquire rid of that. As experience has shown, airdrome is one of the sensitive topographic point that need to continue. Therefore, all airdrome must necessitate to hold tough security or else that can be highly unsafe non even for riders it besides can be a menace for a individual who merely sit at place and read intelligence paper! We can retrieve the catastrophe event on september.11 many people was dead on that happen. I believe that, Criminals do what of all time for achieve thier ends and if we do nt halt them they will halt us. So, we ca nt pretermit to attending of airdrome. In this peculiar instance, we should use of new engineerings at the airdrome such as: security camera, Walk-through metal sensor, Digital radiographic ( X-ray ) organic structure scanner, X-ray backscatter scanner, Millimetre wave organic structure scanner and Handheld metal sensor / baseball mitts. Now we can concentrate on our chief location which is an international airdrome in Hong Kong and they use of these engineerings to forestall illegal act and they besides try to protect of people. It might be helpful to hold an debut of the airdrome and direction portion. The Airport Authority Hong Kong ( AA ) is a statutory organic structure with a authorization to maximize the value of Hong Kong International Airport ( HKIA ) for the benefit of the territory.Established in 1995 to run and keep HKIA, and with an accent on heightening Hong Kong s position as a major Centre of international and regional air power, the AA is entirely owned by the Government of the Hong Kong Special Administrative Region ( HKSAR ) .The AA is governed by the Airport Authority Ordinance and its Board comprises a Chairman, CEO and between eight to 15 other members. With a direction squad strengthened by expertness from the commercial sector, AA s 1,100-strong staff take an entrepreneurial attack to developing HKIA into a preferable international and regional air power Centre and an engine of economic growing for Hong Kong.With this aim in head, the AA s concern doctrine is to farther expand HKIA s planetary air power web and supply riders with more finishs, greater frequenc e of flights and a wider pick of bearers. Riding on Hong Kong s strategic location and HKIA s world-class installations, the AA is widening the airdrome s place market to the Pearl River Delta country and beyond.The AA remains committed to the highest possible degrees of security and safety. It works to continuously raise security criterions while understating hold and incommodiousness to passengers.As a responsible corporate citizen, the AA novices and takes portion in a broad scope of programmes and activities that promotes environmentally friendly patterns, people development and community improvement.

( www.hongkongairport.com ) Scenario With this debut we may now turn to our chief disscusion about how we can hold a secure airdrome and how metal sensor is exremely functional. Basically, walk-through metal sensors used to happen metal arms and metal object. I believe that, all devices have some jobs that it needs to better. But most of these device are utile except some of them which is useless. So, we should concentrate on devices which is utile and seek to extinguish jobs that emerge on them. After this scenario, I feel it is critical to hold a definition of metal sensor. Walk-through metal sensor A metal sensor is a device which utilize electromagnetic initiation to detect metal. This is besides the prevalently used system at most international airdromes. Regular standardization of the archway is demanded to guarantee stable sensing public presentation. ( www.legco.gov.hk/yr09-10/english/ /se/ /se_phsw1116cb2-257-1-e.pdf ) This device can fall into 13 chief portion as demonstrate below: 1.2.1 Alarm Indication A signal to warn of the sensing of a metal object. The indicant can be ocular and/or auditory. 1.2.1.1 Positive Alarm Indication The alteration in the dismay indicant that corresponds to the sensing of a metal object. Typically, the dismay indicant is off until a metal object is detected. 1.2.1.2 Proportional Alarm Indication An dismay indicant proportional to the size, propinquity, orientation, and stuff of an object. 1.2.2 Alarm Index The device used to bring forth the dismay indicant. For a ocular indicant, the dismay generating device can be a light bulb, lamp, light breathing rectifying tube, etc. For an audile indicant, the dismay bring forthing device can be a horn, Siren, doorbell, or similar point. 1.2.3 Active Detector An active sensor is by and large a device that generates energy for lighting the portal part of the sensor. For the walk-through metal sensor, the generated energy is in the signifier of a magnetic field. The interaction of the generated magnetic field with certain types of objects in the portal part of the sensor and the ability to observe this interaction is the footing of operation for walk-through metal sensors. 1.2.4 Clean Examiner A individual who does non transport any electrically conductive and magnetizable objects such as metallic belt buckles, metal buttons, cardiac pacesetter, coins, metal-frame spectacless, hearing assistance, jewellery, keys, pens and pencils, places with metal arches or supports, metallic surgical implants, undergarment support metal, metal slide fasteners, and similar points, which would significantly change the signal produced when the individual carries a trial object. 1.2.5 Detection The find or determination of a metallic object. The sensing of a metallic object is transmitted to the operator by some type of dismay index, typically a ocular or hearable index. 1.2.6 Detector Axis An fanciful line go throughing through and perpendicular to the sensor plane that is centered vertically and horizontally within the portal of the walk-through metal sensor and points in the way of the topic s gesture through the portal. 1.2.7 Detector Floor The bottom plane of the sensor portal. 1.2.8 Detector Mount A nonconducting, nonmagnetic platform on which the walk-through metal sensor remainders. The sensor saddle horse locates the sensor floor at a tallness of 32.5 centimeter ( 12.8 in ) and contains channels at 10 centimeter ( 4 in ) below its top surface to ease the metal floor trial required under subdivision 3.4.2. The 1.2.9 Detector Plane An fanciful plane ( planar surface ) that is parallel to the portal of the walk-through metal sensor and that bisects the detector part into two symmetric halves. The sensor plane contains two extraneous axes labeled the ten axis and the omega axis. 1.2.10 Detector Positioner A nonconducting, nonmagnetic device that fixes the place of the sensor plane and sensor axis with regard to the three-axes interlingual rendition system. The sensor rotary actuator includes a mention surface for attaching the sensor saddle horse. The sensor rotary actuator besides includes a surface for fond regard to the three-axes interlingual rendition system. 1.2.11 Detector Response The electrical signal generated by the detector or detector circuit of the sensor and caused by an object interacting with the magnetic field generated by the sensor. The sensor response is the footing on which an dismay indicant is derived. 1.2.12 Ground Surface The surface on which the walk-through sensor remainders. 1.2.13 Measurement Coordinate System A reciprocally extraneous 3-dimensional Cartesian co-ordinate system referenced to the sensor axis and the sensor plane. The three axes are labeled ten, Y, and omega, where the Y axis is parallel to the sensor axis and the ten and omega axes are in the sensor plane. The orientation of the trial objects and way of the magnetic field is referenced to the measuring co-ordinate system. ( www.ncjrs.gov/pdffiles1/nij/193510.pdf ) Advantages and disadvantages Many old ages that Metal sensor have been used. In this portion I want to concentrate on some advantages and disadvantages that appear in this device. The advantages of a walk-through metal sensors include: no radiation is generated during showing ; easy installing albeit bulky by comparing to handheld metal sensor ; high velocity sensing capableness ( about 15 msecs ) ; and the capableness to observe big metal objects like knives and guns. The disadvantages of a walk-through metal sensor include: it merely detects metallic objects ; it is easy interfered with by metals that exist in the edifice environment such as ceiling with metallic stuffs and Fe reinforcing bars in walls and floors ; and the demand for regular standardization to guarantee stable sensing public presentation. ( www.legco.gov.hk/yr09-10/english/ /se/ /se_phsw1116cb2-257-1-e.pdf ) There is yet another job with conventional walk through metal sensors is that they are heavy and hard to travel assorted locations. Another job with conventional walk through metal sensors is the power ingestion of the electronic system limits the sensors ability to run from a battery beginning for more than a few hours, necessitating AC power to be accessible for either operation, or frequent battery recharging. ( www.freepatentsonline.com/7145456.html ) Similarities and differences between human facets with subject above: ( HCI ) human computing machine interface. This sentence can be divided into three chief categorize: homo which means all single or group of users that they work together and they use of engineering. As we all know, computing machine is non merely include Personal computer or laptop. So, any engineering such as photocopiers, hair drier, metal sensor, etc. can be a computing machine. Interaction is Communication between user and computing machine. If we focus on human computing machine interface it s obvious that the indispensable portion of that is about Concern with the user executing and Produce utilizable and unafraid system every bit good as practical system. It besides tries to better some of import parts such as: Safety, usefulness, impressiveness, competency, convenience for usage and Simplicity. Another similarity between this device with ( HCI ) is about wellness concerns. There s no radiation is created during testing. Consequently, it ca nt be unsafe for users. It is besides ergonomic because of efficiency and safety. There is different between this device with ( HCI ) is about green computing machine which try to diminishing electricity and environmental waste during utilizing computing machine and one of the of import job is approximately battery that we explained in disadvantages portion. Similarities and differences between securities with subject above: As indicated, walk trough metal detecor is a computing machine that need to concern and ca nt pretermit to it. In this instance, we can advert to computing machine security hazard which is an action that causes licking of or harm to computing machine system. At this point, I think it is helpful to hold some information about system failure that induced by aging hardware, natural catastrophes, or electrical power perturbations. In add-on, there might be overvoltage or power rush that can assist to system failure to damage the device. So, we should put in a rush defender which Protects computing machine and equipment from electrical power perturbations and it besides, Uninterruptible power supply ( UPS ) that provides power during power loss. On the other side, consideration to some factors as an illustration of air humidness is mandatory. The difference between security and the metal sensor is that in some sort of these devices the companies has installed a camera that can enter picture for approximately 24 hours and it besides can take back up of that. As we know, there are four types of dorsum up: full, differential, incremental and selective. But in these devices we merely have one option which is full. Similarities and differences between Ethical with subject above: proposals As this device is extremely functional we need to better it every bit good as we can. Therefore, I have some thought to do it better. In my position, this device can be more helpful every bit long as it use less electricity, in this manner we are more close to green computing machine. Another construct that I feel it might be hepful is that, put in security camera that can enter picture with rapid climb ability. This manner can assist to acknowledge a individual who we re looking for. As we all know, if we wear metal belt we ca nt go through through the walk through metal sensor and it s a large probelm because at the airdrome rider need to acquire their belt off. On one manus, it takes clip. So, one believe that we can make a device to scan riders organic structure to observe it. Then, we can calculate this job out. Decision In amount up, I reflect my sentiment once more and asseverate that, in my position, we should heighten our engineerings and use those in approprate ways. As I ve probed about the airdrome that uses metal sensor to detect arms and some illegal metal objects and if they do nt utilize of the device what can go on. I have besides expounded how that device can be extremely functional at the airdrome. In add-on, I notified some advantages and disadvantages that emerge in metal sensor. Afterwards, I claimed some similarities and differences between the subject above with security, Human Aspect and .. . Finally, I ve besides illustrated some recommend that we how we can extinguish disadvantages in metal sensor in that manner this device can be more utile. Refrences Information about the airdrome such as director, history, mission and responsibilities.

The Catcher in the Rye Themes, Symbols, and Literary Devices

'The Catcher in the Rye' Themes, Symbols, and Literary Devices J.D. Salinger’s The Catcher in the Rye is a classic coming-of-age story. Narrated by sixteen-year-old Holden Caulfield, the novel paints a portrait of a struggling teenage boy as he attempts to hide his emotional pain behind cynicism and false worldliness. Through the use of symbolism, slang, and an unreliable narrator, Salinger explores themes of innocence vs. phoniness, alienation, and death. Innocence vs. Phoniness If you had to choose one word to represent The Catcher in the Rye, it would be phony, Holden Caufield’s insult of choice and a word he uses to describe most of the people he meets and much of the world he encounters. For Holden, the word implies artifice, a lack of authenticity- pretension. He views phoniness as a sign of growing up, as if adulthood were a disease and phoniness its most obvious symptom. He has moments of faith in younger people, but invariably condemns all the adults as phonies. The flip side of this is the value Holden puts on innocence, on being unspoiled. Innocence is typically assigned to children, and Holden is no exception, regarding his younger siblings as worthy of his affection and respect. His younger sister Phoebe is his ideal- she is intelligent and perceptive, talented and willful, but innocent of the terrible knowledge that Holden himself has gained with his extra six years (most notably concerning sex, which Holden wishes to protect Phoebe from). Holden’s dead brother, Allie, haunts him precisely because Allie will always be this innocent, being deceased. Part of Holden’s torment is his own phoniness. While he does not consciously indict himself, he engages in many phony behaviors that he would abhor if he were to observe them in himself. Ironically, this prevents him from being innocent himself, which explains to some degree Holden’s self-loathing and mental instability. Alienation Holden is isolated and alienated throughout the entire novel. There are hints that he is telling his story from a hospital where he is recovering from his breakdown, and throughout the story his adventures are consistently focused on making some sort of human connection. Holden self-sabotages constantly. He feels lonely and isolated at school, but one of the first things he tells us is that he’s not going to the football game everyone else is attending. He makes arrangements to see people, and then insults them and drives them away. Holden uses alienation to protect himself from mockery and rejection, but his loneliness drives him to keep trying to connect. As a result, Holden’s sense of confusion and alarm grows because he has no true anchor to the world around him. Since the reader is tied to Holden’s point-of-view, that terrifying sense of being completely cut off from everything, of everything in the world not making sense, becomes a visceral part of reading the book. Death Death is the thread that runs through the story. For Holden, death is abstract; he’s not primarily afraid of the physical facts of the end of life, because at 16 he can’t truly understand it. What Holden fears about death is the change that it brings. Holden continuously wishes for things to remain unchanged, and to be able to go back to better times- a time when Allie was alive. For Holden, Allie’s death was a shocking, unwanted change in his life, and he is terrified of more change- more death- especially when it comes to Phoebe. Symbols The Catcher in the Rye. There’s a reason this is the title of the book. The song Holden hears contains the lyric if a body meet a body, coming through the rye that Holden mishears as if a body catch a body. He later tells Phoebe that this is what he wishes to be in life, someone who catches the innocent if they slip and fall. The ultimate irony is that the song is about two people meeting for a sexual encounter, and Holden himself is too innocent to understand that. The Red Hunting Hat. Holden wears a hunting cap that he frankly admits is kind of ridiculous. For Holden it is a sign of his otherness and his uniqueness- his isolation from others. Notably, he removes the hat whenever he is meeting someone he wants to connect with; Holden knows full well the hat is part of his protective coloring. The Carousel. The carousel is the moment in the story when Holden lets go of his sadness and decides he will stop running and grow up. Watching Phoebe ride it, he is happy for the first time in the book, and part of his happiness is imagining Phoebe grabbing for the gold ring- a risky maneuver that could get a kid a prize. Holden’s admission that sometimes you have to let kids take risks like that is his surrender to the inevitability of becoming an adult- and leaving childhood behind. Literary Devices Unreliable Narrator. Holden tells you he is the most terrific liar you ever saw. Holden lies constantly throughout the story, making up identities and masking the fact that he’s been kicked out of school. As a result, the reader can’t necessarily trust Holden’s descriptions. Are the people he calls phonies really bad, or is it just how Holden wants you to see them? Slang. The story’s slang and teenage vernacular are out of date today, but the tone and style were remarkable when it was published for the way Salinger captured the way a teenager sees and thinks about things. The result is a novel that still feels authentic and confessional despite the passage of time. Holden’s style of telling the story also underscores his character- he uses profanities and slang words very self-consciously to shock and to demonstrate his jaded and worldly ways. Salinger also employs the use of filler phrases in Holden’s story, which gives the narrative the feeling of being spoken, as if Holden were actually telling you this story in person.

English-language films Essay Example for Free

English-language films Essay Many people wonder these days if peoples lives revolve around the choices they make. This is absolutely true. Everyone in this world is responsible for who they are today. Their choices and ideas pave the road for their future. A quote from Confucius says this, Peoples lives are the result of the choices they make-or fail to make. The path one takes in life is not arbitrary. Choices and their consequences determine the course of every persons life. All people, whatever their circumstances, make the choices on which their lives depend. Confucius is absolutely right. It is a well-known fact that if you take wrong turns in life, you will end up in a wrong state. The regular human psychology states that when a person goes and ends up in a bad state, they blame others and most of the time never take responsibility for it. Take a look at this scene, and look carefully cause this happens all the time no matter the circumstances. There is no way and it is impossible for a child who takes drugs, does alcohol, doesnt obey their parents to find themselves at an Ivy-League college. Sometimes, people change their paths along the way and somewhat improve. But if you keep going in the wrong direction for your entire life, you will not get anywhere. Think about the people who are successful in this world. For examples, lets observe Mark Zuckerberg. He is the youngest billionaire in the world. He was focused, he was determined. In fact he was so passionate about programming that he dropped out of Harvard, the number one school in America. He used his talents, worked his choices and made Facebook. Not all of his choices were good. Some were actually bad; some choices actually got him into trouble with others. This is where the trouble comes in. Wait if some of my choices are good, and some are bad, then whats going to happen with my life? Nothing will actually. All that matters is that the majority will overcome the system. If you have more bad than good, you are more likely to take a wrong turn. If you have more good over wrong, you will most likely take a good turn. Even I have taken wrong turns and bad choices. Everyone has. Nobody in this world is perfect. In fact, taking all good choices and all good turns in life ends up as a bad choice. Even though nobody is perfect, its your own self that will determine your future, what you want to become, your status in life. Thats why its good to switch your determination in life if you are on a bad path. Stick with someone and change your mood. Change your attitude, fix your choices, and keep yourself organized. If you are a person reading this essay, lets say about 12 or 13, even 14 to 18. You still have time. You have so much future ahead of you, dont give up hope cause your choices sometimes do tell your future. Sometimes these choices of yours will end you up in a bad place if you dont work hard. A wise person, my own father once told me that it doesnt make you a bad person if you take bad choices. It makes you a bad person if you dont learn from your bad choices. He also told me that if you want to be someone when you grow up, work hard. In elementary, in middle school, and in high school, work hard so that you can build your base for the future. He concluded with me that once you pay off all your duties, go to college, and graduate, you have the rest of your life to enjoy. Whether its doing your dream job, making millions of dollars, then retiring into a large estate. This is called a dream. If you have more good choices in life, your dream will come to. Trust me, its always worked before.

Improving Focus and Academics in the Classroom Environment with Sit-Sta

Attention-deficit/hyperactivity disorder (ADHD) is becoming an increasing problem for children in America. According to Understanding Abnormal Psychology, it is one of the most common disorders among children entering the classroom (Lyons, Martin, 2009). Although children have a lot of energy to burn, as they enter school they are required to sit still for long hours. Children with and without ADHD have had a hard time staying focused and have suffered academically. If the classroom environment is improved then children will be more productive and be able to focus for longer periods of time. Declining academic scores and increasing diagnoses of ADHD in children bring new challenges to the traditional classroom. Throughout a typical day physical activity among children in traditional public schools can be increased with an ergonomically structured classroom. Physical activity has been shown to increase memory and cognitive function among children and adults (Carlson, Fulton, Lee, Maynard, Brown, Kohl, Dietz, 2008). Additionally, physical activity helps lower the incidence of behavioral issues in the classroom and beyond (Carlson, et al, 2008). Evidence gathered regarding physical activity and cognitive and social development suggests that physical activity increases mental health and cognitive functions (Tomporowski, Davis, Miller, Naglieri, 2007). The classroom environment does not effectively consider the best ways for children to be attentive and succeed. Replacing traditional sit down desks with sit-stand workstations will improve the focus and academic achievements of children in school (Benden, Blake, Wendel, Huber, 2011). A sit-stand workstation with stool is a desk that allows students to either sit or stand... ...ng, CA: Horizon Textbook Publishing. Nemko, M. (2004-2012). The problem with boys.

How does Shakespeare demonstrate the power of the mind in Macbeth? Essay

Macbeth is a play famous for murder and its references to blood. It is usually associated with bad luck and evil; however, there is one main issue that appears time and time again throughout the play – what is it that drives the characters to do the things that they do? Shakespeare explores and presents the power of the mind in many interesting ways. These include soliloquies and slight changes in characters such as the way they talk, act or present themselves. The main character affected by the power of his mind is, of course, Macbeth. What happens in his mind basically provides the plot for the whole play. Once the witches have told Macbeth that he will be king he can either choose to ignore this piece of information or do something about it to make it come around faster. Macbeth chooses to do the latter and he kills the current king, Duncan. Lady Macbeth becomes so caught up in the series of events and excited at the prospect of being Queen that she urges Macbeth on, encouraging him to fulfil his apparent destiny and become King. In the end, the way that Macbeth presents himself and talks is completely different to the character we are introduced to at the beginning of the play. This is all due to the effect his mind power has over him. We also see changes in Lady Macbeth’s character such as paranoia and slight changes in the way she talks and thinks. The first evidence we see of mind power is in Act 1, Scene 3 where Macbeth meets the witches. Why do the witches’ prophecies in this scene have such power over Macbeth? Although Macbeth and Banquo hear the same thing, Macbeth is much more moved by the words, and I think the main reason for this is that the witches’ are speaking Macbeth’s innermost, dangerous thoughts. Once the witches say ‘Hail to thee, Thane of Glamis!’ (Macbeth’s current title) it becomes apparent to Macbeth that the witches are knowledgeable and are capable of predicting the future. Shakespeare constructs the plot cleverly here. The dramatic irony of the audience knowing he has been crowned Thane of Cawdor ensures that the audience are already aware of what the witches can do before Macbeth realises. The tragedy is often blamed on the witches because they torment Macbeth by speaking his thoughts in riddles and they make Macbeth think that his greatest prize is near. However, the witches could only have so much power over Macbeth if he already had these thoughts in his head. Therefore, Macbeth himself could be blamed for the tragedy of the play. If he had already thought about killing Banquo, but thought nothing of it until the witches had confirmed the idea, you could blame him entirely for the murder. The witches know what to say and exactly how to say it, which implies that they know what Macbeth is thinking. Another line in this scene which suggests that Macbeth had already thought about becoming King or killing Duncan is when he pleads with the witches to ‘Stay you imperfect speakers. Tell me more.’ The fact that he was willing to listen to more of what the witches had to say suggests that he had thought of becoming King before and was reassured by the idea that it could really happen. Once the witches have vanished, Macbeth and Banquo visit Duncan at a room in his palace. Here, Duncan appoints Macbeth Thane of Cawdor. It is here that Macbeth begins to fully realise the impact the witches’ words are having on him. He also sees that they knew what was going to happen to him because they had said, ‘All hail Macbeth! Hail to thee, Thane of Cawdor’ in the previous scene. In a powerful soliloquy, Macbeth reveals his thoughts to the audience: ‘†¦Stars, hide your fires! Let not light see my black and deep desires;’ With ‘let not light see my black and deep desires’ Macbeth confirms that he has thought of becoming King before, but does not want to show it. When he was speaking with the witches he wasn’t sure whether to believe what they were seeing and although he did think about the idea of becoming King, he never really pursued it. Once the prophecy of Macbeth becoming Thane Of Cawdor comes true, Macbeth realises that he will be king. In Act 1, scene 7 Macbeth is considering murdering Duncan but says there are many arguments against it. Some of the lines in this scene make me wonder whose initial idea the murder was and whether Macbeth really wanted to kill Duncan. Macbeth says he is enjoying the feeling of being famous and powerful but Lady Macbeth’s persuasion quickly works on him: ‘I am settled and bend up each corporal agent to this terrible feat.’ In the second act when Macbeth decides he is against the idea, the more persuasive Lady Macbeth is towards him, the more Macbeth submits to her taunting – ‘When you durst do it, then you were a man; And, to be more than what you were, you would be so much more the man.’ By the end of the scene, Macbeth has been made to feel so inferior by Lady Macbeth that he has taken over the planning himself. Macbeth plans to blame the murder on the two guards in Duncan’s chamber: ‘Will it not be receiv’d, When we have mark’d with blood those sleepy two Of his own chamber, and us’d their very daggers, That they have done’t?’ Temporarily, Macbeth has lost his doubt and fear in the excitement of planning the murder. Perhaps the most famous act of mind power in this play, is the dagger Macbeth sees in Act 2, Scene 1. It is late at night in the castle and Macbeth meets Banquo and Banquo’s son Fleance. Banquo wants to talk about the witches’ prophecies to Macbeth. Banquo says that he has dreamt of the sisters and seems to be annoyed because they have ‘showed [Macbeth] some truth.’ Just as the three Weird Sisters predicted, Macbeth’s wishes and secret dreams of power have all come true. But along with these, so have his darkest fears. Throughout the play Macbeth continues to struggle against the images his mind conjures up against his own conscious will. Although technically, he has won the crown and been successful, he cannot enjoy himself because of the immense guilt he feels over how his mind has been poisoned by the Weird Sisters. The dagger scene is an extremely powerful example of mind power. Shakespeare uses metaphors, imagery and other dramatic cues to express Macbeth’s emotions and fear. Probably the most well known line in the play, upon seeing the dagger Macbeth says to himself, ‘Is this a dagger I see before me, The handle toward my hand?’ Macbeth realises that the dagger is only a vision created by his mind, in this question he is questioning his mind – asking himself whether what he is seeing is real or a figment of his imagination. He continues, ‘†¦art thou but A dagger of the mind,’ The way Shakespeare has written Macbeth’s speech make it seem so much more realistic. Because this play would first have been performed in a Jacobean theatre, there would have been no special effects in the theatre to emphasise the visions Macbeth’s mind were creating throughout the play. The actors would of course had to have been talented to pull off such acting without props, but the choice of words Shakespeare uses it what makes it so much more believable. Act 2 Scene 3 is the morning after the murder. In this scene Macbeth shows a variety of different emotions so it is difficult to tell what he is feeling about the murder. Also, what Macbeth says in this scene is quite ambiguous so it is quite hard to figure out what he means. When Macbeth says ‘Twas a rough night’ it could either mean that he is shocked by the night’s events or that he fears being found out. And when Macbeth says ‘Had I but died an hour before this chance I had lived a blessed time’ it is relatively easy to see that he feels guilty and regrets the murder. Another change in Macbeth’s speech is that his statements seem to be shorter and more formal. This suggests that he is on edge and is worried about being found out. In this scene, Macbeth also decides to start acting secretly, and does not communicate his plans with Lady Macbeth – ‘Be innocent of the knowledge †¦ ’till though applaud the deed’. Another major demonstration of mind power in the play is when Macbeth conjures up the image of Banquo’s ghost at the banquet in Act 3, Scene 4. Thinking about why Macbeth is so tense and anxious when he enters the room helps you to understand how his mind could have conjured up the terrible image of the ghost. Macbeth is obviously worried and guilt-ridden about Banquo’s murder, he says ‘I had else been perfect †¦ but now, I am bound in to saucy doubts and fears.’ Banquo was Macbeth’s best friend, and Macbeth had ordered him to be killed. He needed both Banquo and Fleance to be killed, but Fleance escaped. Macbeth excluding his wife from the plans is putting extra pressure on him, not to mention the relationship between the two. The banquet is the first function that Macbeth organises when he is appointed King. Therefore, he needs his guests to feel that he is a good King and is control of the banquet. When Macbeth sees the ghost and everything starts to go wrong, Macbeth is desperate to calm his important guests so that they do not think of him as not being a fitting King. The ghost in Act 3, scene 4 has an extremely powerful effect on Macbeth. He goes through different stages of acceptance, first cowering from it, then challenging it and finally, confronting it. ‘†¦the time has been, That, when the brains were out, the man would die, And there an end; but now they rise again, With twenty mortal murders on their crowns and push us from our stools†¦Ã¢â‚¬â„¢ Macbeth’s fear of the ghost is completely natural. He cannot understand how Banquo could have reappeared, especially after having just been informed of his death. He challenges the ghost, ‘Hence, horrible shadow! Unreal mockery, hence!’ Macbeth confronts the ghost, ‘Thy bones are marrowless, thy blood is cold; Thou hast no speculation in those eyes, Which thou dost glare with.’ The ghost disappears at these words and Macbeth seems to have won by confrontation. Macbeth returns to his guests. Macbeth doesn’t realise that no one else in the room can see the things he is imagining – he assumes that they saw the ghost and is surprised by their apparent failure to react to it, ‘†¦now I think you can behold such sights, ands keep the natural ruby of your cheeks, when mine is blanched with fear.’ The sleepwalking scene is one in which Shakespeare demonstrates mind power through actions very well. Lady Macbeth is subconsciously ridden with guilt over the deaths. When she sleepwalks we see her vigorously washing her hands to scrub Duncan’s blood from her hands and asking no one in particular ‘†¦who would have thought the old man to have had so much blood in him?’ Of course, Lady Macbeth does not still have Duncan’s blood on her hands; it is only her imagination making her think she needs to scrub her hands clean – ‘†¦all the perfumes of Arabia will not sweeten this little hand.’ Lady Macbeth is usually seen as dominant over Macbeth, she tries to seem stronger than Macbeth and hides her fear, guilt and shame as much as possible. The way that Lady Macbeth weakens when asleep creates a very powerful image of mind power. By scrubbing her hands over and over again we can guess that, rather than trying to rid her hands of blood, she is actually trying to rid her mind of the memories of the night of Duncan’s murder. The doctor who has been called to help Lady Macbeth says that the disease is ‘beyond his practice’ and that ‘more needs she the divine than the physician.’ meaning that she has more need for a priest than a doctor to rid her of her ‘evil disease’. Lady Macbeth leaves the room soon after muttering that ‘what’s done cannot be undone’ and repeating that she must go to bed. The doctor continues trying to analyse Lady Macbeth’s disease and confides in her gentlewoman, telling her that ‘Foul whisp’rings are abroad†¦ †¦infected minds To their deaf pillows will discharge their secrets.’ The doctor knows Lady Macbeth is hiding something – when he says ‘deaf pillows’ it suggests that people reveal their secrets to pillows because they are deaf and therefore cannot hear or repeat what they have done. Shakespeare’s use of language is just as important as the actions of the characters in showing how powerful their minds are. Macbeth seems weary when he is told of Lady Macbeth’s death – ‘She should have died hereafter: There would have been a time for such a word.’ It is a strange reaction – he is suddenly quiet, thoughtful and almost subdued. His drive and motivation disappear. Macbeth no longer sees any point in trying to hold on to the kingship, and does not understand why he ever wanted it. †¦[life] is a tale Told by an idiot, full of sound and fury, Signifying nothing’ Macbeth also thinks that his time is coming to an end and he will die soon. He says that his actions in the past have ‘lighted the fools way to dusty death’. It seems as though, no matter what happens from this point on in the play, Macbeth can no longer return to being the person he was before the Witches poisoned and taunted him with ambition. On the battlefield, Act 5, Scene 8 Macbeth dares each man on the battlefield to kill him in the face of his seemingly infallible prophecy. ‘Why should I play the Roman fool, and die On mine own sword? Whiles I see lives, the gashes Do better upon them.’ Roman generals in defeat would commit suicide to avoid the disgrace of capture, but, in this speech Macbeth says that while he can see living enemies, he will do his best to kill them. He continues taunting his enemies until Macduff kills him. Macbeth finds out that Macduff was from his mother’s womb untimely ripped’ which is what the Witches told Macbeth earlier in the play. At this point, Macbeth realises his life has come to an end and knows that he will not survive the fight with Macduff, however he is brave enough to fight on to the end. An interesting idea is to think about who was truly responsible for the tragedy in Macbeth, other than the witches. Macbeth himself had already thought about the kingship before being told by the Witches that he could achieve it and listens willingly to what the Witches tell him. However, when the plan has been hatched, Macbeth begins to back off until Lady Macbeth taunts him enough to convince him to take over the planning again, which he eventually does. Also, many of Macbeth’s speeches are filled with threats, evil and darkness. Mind power plays a large part in Macbeth’s character – having already thought of the kingship, he was really only waiting for confirmation from someone else before acting on his thoughts. Lady Macbeth also plays a major role in the tragedy. She becomes obsessed with the news she is sent by Macbeth, and immediately hatches a plan to achieve the goal. Her speeches, not dissimilar to Macbeth’s, are also full of darkness and double meanings. When Macbeth backs down and is not so sure about the plan, she taunts him until she finally persuades him to continue. It is also Lady Macbeth who takes the knives back down to the servants after the murder and tried to make everything normal again. Lady Macbeth is greatly affected by her mind, which we see particularly in the sleepwalking scene where she continually washes and rubs her hands in an attempt to scrub away what she believes to be Banquo’s blood. At the beginning of the play, Macbeth is a great man. After meeting the Weird Sisters he begins to make bad choices and gets everything wrong. The effect the three Witches have on Macbeth’s subconscious mind is astonishing – they make him see things, hear things and do things he doesn’t really want to do. Along with Lady Macbeth, the Witches’ taunting and riddles possess Macbeth and turn him into a power-obsessed, ambition-crazed ‘fiend’. However, Macbeth redeems himself at the end of his life and does not die as the villain of the play. Macbeth is a tragic hero – possessed by evil thoughts, but able to redeem himself by being brave enough to fight on to the end, even though he knows he cannot win back his sanity and/or peace of mind.
