Macbeth Who was responsible for King Duncans murder Essay Example

Macbeth: Who was responsible for King Duncans murder Paper In my opinion, there are three main people that should be held responsible for the death of King Duncan: Lady Macbeth, the witches and of course, Macbeth himself. In this essay, I will be looking at the three people and how they each played a role to cause the death of Duncan. Firstly, I think that Lady Macbeth was hugely to blame. We see that both husband and wife are highly ambitious and hope to achieve a lot. Macbeth trusts Lady Macbeth and is very close to her. He informs her straight away of his meeting with the witches through a letter in which he also calls her his dearest partner of greatness. This shows us that they are close and are partners or colleagues in everything. As soon as Lady Macbeth reads the letter, she is already making plans to achieve Macbeths title as the King and hers as the Queen. We see this when she says That I may pour my spirits in thine ear/And chastise with the valour of my tongue. This could give away a hint of evil in her to us. In addition, we see that she fears that Macbeth is too kind to achieve it. This means that she is already thinking that there is dirty work involved and Macbeth is too incapable of doing it. We will write a custom essay sample on Macbeth: Who was responsible for King Duncans murder specifically for you for only $16.38 $13.9/page Order now We will write a custom essay sample on Macbeth: Who was responsible for King Duncans murder specifically for you FOR ONLY $16.38 $13.9/page Hire Writer We will write a custom essay sample on Macbeth: Who was responsible for King Duncans murder specifically for you FOR ONLY $16.38 $13.9/page Hire Writer She says that he lacks the illness that should attend the ambition. She also thinks that Macbeths nature is too full o the milk of human kindness. This shows us that Macbeths natural instincts would be to leave this prophecy and wait for it to come to him, not commit the murder. Therefore, we could argue that Macbeth is a kind-hearted man who was innocently wound up and captured in his wifes evil plans of regicide. We can see this supported hugely when Macbeth is reluctant to carry out the murder and refuses to do so. Lady Macbeth steps in and presses on, using different techniques to make Macbeth change his mind. At first, she mocks him saying Was the hope drunk/Wherein you dressd yourself? Then, she begins making him feel guilty, making him think that his love for her is shaky. Because they are so close, we could see this as an insult. She says to him From this time/Such I account thy love. She also makes him feel guilty by telling him that she knew what it was like to breast-feed and she knows how tender it is to love the baby that milks her, but she would have plucked the baby from her nipple and dashed its brains out if she had promised to do so, like Macbeth had done to their promise of killing the King. She also questions him, asking whether he would like to live a coward. Another technique she uses is questioning Macbeths manhood, making him feel low. Soon Macbeth was trapped in her persuasion and manipulation, and gave into the murder. Lady Macbeth also seems to have a manly, monstrous side to her. Its almost as if shes tired of being a dainty woman and wants evil to enter her so she may achieve more, with the help of evil spirits. She calls upon the spirits to come and unsex her. She also says to the evil spirits to stop up the access and passage to remorse. In other words, she does not want the natural feelings of remorse and regret to get in her way because she is so determined to do the murder. We could say that Lady Macbeth is already on the evil side, stopping herself from any natural feelings. We could argue that she is the driving force behind the whole murder and she is the only reason Macbeth killed Duncan. However, Macbeth is accountable for his actions and he had complete control over what he was doing. Lady Macbeths character shows us how eager she is to achieve high positions and we see that she will let nothing get in her way or stop her. Her character and actions play a big role in the murder. They are the two things that convince Macbeth to murder Duncan. The witches also play a very important role in Macbeth because some people argue that they put the idea into Macbeths head. In those times, the topic of witches or evil spirits was something very serious. It was so serious, in fact, that the king of the time, wrote a book about demons and evils, such as witches. A lot of people took interest in this field and many precautions were taken to protect themselves form witches and evils of the sort. In contrast to today, witches were not amusing subjects and their prophecies were, in a way, very valuable. The witches know when to appear, and purposely appear at the right moments to play on Macbeths conscience and manipulate him to do things. They know exactly how and when to enter so that the most amount of tension and dramatic effect is created at the right times. Shakespeare uses the witches very carefully to create the right dramatic effects and moods. When being performed in the Globe Theatre, there were no special effects or any dramatic lighting to create atmospheres. So, Shakespeare used stagecraft and the entrances of the witches to get the audience to feel the tension. Also, on their first meeting, the witches leave Macbeth and Banquo confused. They give unsteady prophecies about Banquo, contrasting against each other. They also seem to know what Macbeth is thinking at all times, to make themselves more powerful in the eyes of Macbeth and use him to create all the havoc. In addition, I think that some people could argue that the witches are entirely to blame because they are so powerful supernaturally, that a normal person like Macbeth would have no control over himself if the witches were ruling him. Their main motive is to create havoc, and Macbeth seems to be the easiest way to do so. Therefore, we could say that he is pulled into their evil plans and its not at all his fault. However, some people contradict this and say that the witches were not sparking any havoc, but rather telling and informing Macbeth of the events to come. Because of their powers, they could see in to the future and so were merely telling Macbeth what was in store for him, but Macbeth took the wrong turning with this information and himself decided to kill King Duncan. We can see that the witches did not refer to regicide in any of their appearances. Maybe, the throne was destined to be his but he did not need to kill Duncan to do so, and because he did, he caused trouble for himself and did not achieve anything. Macbeth, from the start, has a very ambitious and determined character. We see that when the witches disappear after stating their prophecies, Macbeth wants them to carry on and is unhappy that they left. We see this when he says, Stay, you imperfect speakers, tell me more. This shows us that he is interested in the witches predictions and wants to know more as he is allured. Also, some say that Macbeth already had the idea of doing something to calm his craving for the throne. When the mention of the Prince of Cumberland comes, he says that it is a step which Macbeth must fall down, or else oerleap. This shows us that Macbeth wants to do something to get rid of him, or move him out of the way. In addition, Macbeth is already thinking evil things. We see this when he says Stars, hide your fires;/Let not light see my black and deep desires. . . Black deep desires could suggest many things. In my opinion, we know that he is planning something evil, although we dont know what. Many people argue that the witches plant the idea into Macbeths head. However, I think that Macbeth already had the idea and was just shocked and scared to hear his thoughts being said aloud. We see this when Banquo says to Macbeth Good sir, why do you start; and seem to fear/Things that do sound so fair? We see that Macbeth fears the witches predictions and there could be a number of reasons for it. He could fear the witches themselves. He could fear the predictions, or, in my opinion, the predictions could be something thats already in his heart but he has learnt to control his ambitions and desires. When the witches speak of the prophecies, it starts the ball rolling and Macbeth is unable to control his actions. He feels inclined toward the witches and their prophecies and wants to achieve what they predicted. Therefore, he gets rid of anything in his way and as a result, kills Duncan. Macbeth takes the witches words quite literally every time and gets himself in even more trouble. For example, the incident of Birnam Wood. Toward the end, Macbeth relies solely on the prophecies, and depends on the witches. Throughout the play, we see him change. At first, he is very shaky and we see Lady Macbeth take control of the situation, leading Macbeth. But, toward the end, Macbeth becomes the leader and her true conscience shows. This is almost a transformation from good to evil for Macbeth. At the end of the day, Macbeth was the one to do it physically, so he should be blamed. He had power over his actions and when committing the crime, he should have been prepared for the consequences of his actions. Aside from the above arguments, I also think there are two other people to blame. They are Banquo and Duncan himself. Although they do not play as big as a role as the other people do, they still hold some blame. Banquo had suspicions of Macbeth but failed to do anything. He knew what Macbeth was thinking and knew he was up to something, but didnt take any action and was so killed. Although Banquos motive may not have been to get the king killed, he still didnt do anything about it. In those times, loyalty to your king was very important. It came before anything. Therefore, we could argue that Banquo had more loyalty toward his friend than toward his King, who should actually come first. In this way, Banquo is partly to blame. I also think that Duncan is to blame because he is too much of a trusting man. He only comes to stay with Macbeth with two bodyguards. Macbeth, who isnt even King, has more bodyguards than the King. Also, the King is too nai ve and vulnerable. Maybe it would have been better that Macbeth was the King because he would be a firm ruler, not a push-over like Duncan. Overall, I think that Macbeth is mainly to blame because at the end of the day, Macbeth did the crime and he went ahead with the plan. We see him change from a good, noble man to a cruel, harsh, evil man.

What is there to investigate Essays

What is there to investigate Essays What is there to investigate Essay What is there to investigate Essay I am going to investigate the effect of how friction acts on a cylinder rolling across a carpet after going down a ramp at a selected angle.Here is a diagram of the apparatus that I will use:Apparatus (The set-up of the items that Im going to use)What it all means and what I will need to measureCylinder 1,2 and 3 represent one cylinder at different stages. Cylinder 1 is the starting point of the cylinder. Cylinder 2 is just before the cylinder goes onto the carpet. Cylinder 1s Potential Energy and Cylinder 2s Kinetic energy are the same value. Cylinder 3 is where the Cylinder has stopped. I will measure the distance that the Cylinder has rolled from the carpet (d), after the Cylinder has left the ramp. I will also measure the height (perpendicular to the carpet) at which the Cylinder falls from. I may also need to measure the mass of the Cylinder. This will help us to work out the potential and kinetic energy. But I wont have to do this till a later stage.Howe ver, I will not need to measure the angle of the slope, because that will always stay the same through out the test (We had to choose one of eight slots in which to put the ramp. If it did not stay the same, it would be an angle versus distance and we are trying to find out height (h) versus distance).Method1. I will set-up the apparatus how it is shown in the diagram.2. I make sure the carpet is right in-line with the ramp.3. I make a rough table of results (in the back of my neat book) making the column headers Height of Ramp and Distance Rolled by the Cylinder4. Then, with a small ruler, measure the height of the place on the ramp where I will start to roll the cylinder from, and make a little mark.5. I write the h (height) in the necessary row.6. I put the cylinder onto the ramp. I let the cylinder go.7. When the cylinder stops rolling on the carpet, I will take the metre ruler, and make sure that the start of the ruler is on exactly the start of the carpet, and I will measure h ow far the cylinder rolls.8. I will write the distance in the correct row and column.9. I then will take another place on the ramp 0.5cm lower.10. I now will repeat steps 4-9 until I have a height of about 0.8cm.11. Then I will copy the results up in neatWhat I Will and will not MeasureI will measure the distance that the Cylinder has rolled from the carpet, after the Cylinder has left the ramp. I will also measure the height (perpendicular to the carpet) at which the Cylinder falls from. I may also need to measure the mass of the Cylinder. This will help us to work out the potential and kinetic energy. But I wont have to do this till a later stage.However, I will not need to measure the angle of the slope, because that will always stay the same through out the test (We had to choose one of eight slots in which to put the ramp. If it did not stay the same, it would be an angle versus distance and we are trying to find out height versus distance). I will also not need to measure the length of the slope.I think what will happen is that the height will be directly proportional to the distance rolled by the cylinder, but I must prove it.What is some Science Involved?Some science involved in this is that the kinetic energy at the bottom of the ramp where the cylinder rolled is equal to the potential energy at the top of where you have started to roll the cylinder. Right in the middle of where you started and the end of the ramp; the Potential Energy and Kinetic Energy are the same.When rolling on the carpet, all the Potential Energy has gone, but there is heat energy. This is caused by friction. In this experiment, two things are affected by friction.The greater the friction there is between the ball and the surface upon which it is rolling, the more quickly it will stop moving. The smoothness of the carpet will also affect how long it will take the ball to stop rolling, for example, smooth sand compared to sand with bumps so make sure all surfaces are as level as possible. In this case the carpet is not very smooth so there will be more friction.PredictionMy prediction will be that the more height there is from the carpet the further the cylinder travels. Therefore they will be proportional.Science involved?If the height doubles, the so does the distance rolled. So what I will use is the distance rolled divide by height. The reason is because when I do this, I predict the answer will be repeated all the time (e.g. if the height is 7 and the distance is 70, D/H would be 10, and if the height was 6, Id expect the distance to be 60, because 60/6=10.)A bit of Working out to Test the PredictionP.E=Potential Energy, m=mass, g=gravity, h= height, f=force, d=distance.P.E=mgh and P.E=fdTherefore mgh=fdI have predicted that h will be directly proportional to d, so mg must be proportional to f.An example: M=0.1, G=10, H= 0.05cm, F=0.083333FD = 0.05 JD = 0.05/0.083333D =0.60If this example is the correct formula, then I have it.Preliminary ResultsThese are the preliminary results:Height of Ramp (cm)Distance (cm)6.8815.3653.8472.3270.87I will collect 13 results. This means I will release the cylinder 13 times at regular intervals of 0.5cm (39 in total because I will collect the reading three times and take the average distance.What have I done?I obtained all the readings at 1.5cm intervals from the heights 0.8cm 6.8cm, which covered a good range because it is measured right from the bottom of the ramp and from the top of the ramp (with the same angle).What will I do?I will obtain all the readings at 0.5cm intervals from the heights 0.8cm 6.8cm, that covers a good range because it is measured right from the bottom of the ramp and from the top of the ramp (with the same angle).Were there any problems? If so what will I do?There were quite a few problems. Some problems that appeared were that:1. There was a drop in between the end of the ramp and carpet. This would not be a fair test because a drop would mean a sort of bounce, which would slow the cylinder down rapidly. What I will do overcome this problem was to place three equal size books, which ensures that there is no drop to the carpet.2. I also think there would have been some human error, but this would be a very minor, e.g. you may accidentally push the cylinder slightly.3. You may start the cylinder in slightly the wrong place. There a big range in the results so I will take the reading three times, and then I will work out the average.What will I do with the Readings to test the prediction?I will make a hand-drawn line graph to show Height v Distance. Distance will be on the x-axis because that is the thing I am trying to find out. On the y-axis will be the height because I can change that manually. I will then draw in the line of best fit. If the graph goes through 0,0 and is straight, then my prediction will be right.I have done a computer graph just to test my prediction. But this is not the final Graph.This is the Computer Graph:It is almost a v ery straight graph and very nearly goes through 0,0. This is only the preliminary graph and it looks right (according to my prediction.)Height of Ramp (cm)Distance (cm)6.8826.3765.8705.3654.8604.3543.8473.3402.8352.3281.8221.3150.89From the evidence I have obtained, I can see straight away that the higher the cylinder is up the ramp, the further the cylinder goes on the carpet. For every 0.5 of a centimetre the height increases, the height increases by 5, 6 or 7 (Average of 6.1666666666.).The speed that the Cylinder rolls down the ramp at can be found by firstly finding the kinetic energy (KE).

This is because there is the same gradient slope is the same and the force of gravity is the same.To get the velocity for a certain height, I have created a formula:It is the height at which the cylinder falls from, divided by 5, and then square root that numberOr: (h/5) = velocityTo find the time taken to stop, you do: height at which the cylinder falls from, divided by 5, and then square root that number and then multiply it by 1.21.2 (h/5)So, I predict that on a cylinder where the height of where it falls is 4.3 cm, the speed of the cylinder at the of the ramp is:4.3/5=0.860.86 =0.927m/sThe time taken for it to stop on the carpet is0.927 x 1.2= 1.112s.The results that I got agree with my earlier prediction because I said, My prediction will be that the more height there is from the carpet the further the cylinder travels. Th erefore they will be proportional. If the height doubles, the so does the distance rolled. So what I will use is the distance rolled divide by height. The reason is because when I do this, I predict the answer will be repeated all the time (e.g. if the height is 7 and the distance is 70, D/H would be 10, and if the height was 6, Id expect the distance to be 60, because 60/6=10.) I was right about this because:When the cylinder was dropped at 6.8cm, it went 82cmWhen the cylinder was dropped at 2.3cm, it went 2882/6.8 = 12.1 (1d.p)28/2.3 = 12.2 (1d.p)They are not exact, but this is de to slight human error, perhaps placing the cylinder 1 or 2mm from the actual starting place.From my graph (Distance travelled by cylinder on carpet versus Height of the Ramp), I saw that the points would not join in a straight line. But then I drew in the line of best fit. This line goes through 0,0 and is straight, so my prediction was right.My conclusion is that for every single millimetre that the cyl inder gets moved higher on the ramp, as long as there is a slope, the more distance the cylinder will travel on the carpet. This is because of gravity, which has a weight of 10N (9.8N). There is friction that is caused by the rolling of the cylinder on the carpet. The Kinetic Energy at the bottom is the same as the Potential Energy at the top. Potential Energy is the same as mass x gravity x height, force x distance. Kinetic Energy is the same as 1/2mass x velocityà ¯Ã‚ ¿Ã‚ ½By working out the Kinetic energy you could work out a lot of other things such as:* Velocity at the end of the Ramp* Acceleration on Ramp* Deceleration on carpet* Time taken to stop on the carpetTo sort out the drop in between the end of the ramp and carpet, the way to get out of that hurdle was simple. You had to place some things (I used 3 books) underneath the carpet, and should make the carpet in line with the bottom of the ramp. You should use something hard and flat (for smoothness).I have found out that the acceleration and, on the same slope, (deceleration on a flat surface), with the same cylinder, will always be the same in m/sà ¯Ã‚ ¿Ã‚ ½.The further down a cylinder is on a slope, the faster it goes.Although the points on the graph are not exactly in a straight line, they are very close to being on a straight line. There are 3 possible inaccuracies in this experiment:* While one is releasing the cylinder on the ramp, he can inadvertently push or hinder the cylinder. Also, one may not place the cylinder on the ramp in exactly a straight line* The distance is only measured to the nearest centimetre and is subject to rounding up or down* The surface where the distance is measured may not be uniform so there is excessive or reduced friction.I think the method I used was good because the graph shows an almost perfect fit.It would be unlikely that these results would just be a coincidence.ConclusionThrough this evidence, a firm conclusion can be drawn, especially from the graph.The higher the cylinder is dropped from, the further the cylinder rolls on the carpet. The evidence of this is firmly supported by the graph. The graph was a straight line going, (or very close to) through 0,0.ImprovementsThe follow improvements would be recommended:* There should be a mechanism that holds the cylinder in place on the ramp, and at the intended height, the cylinder can be released without aiding or hindering it.* The ground surface must be uniform.* There should be a mechanism, which ensures that the cylinder is in a straight line at the release of it.* A computerised device that measures the distance in millimetres, or even micrometers could measure the distance that the cylinder travels.* The cylinder should be a perfect cylinder with perfect grooves or dents.Further workOne could:* For each point on the ramp, repeat the experiment ten times, and then take the average.* One could do the experiment with different sorts of cylinderso Wooden cylinderso Different metal cyl inderso Hollow cylinderso Different sized cylinders* One could repeat the experiment but instead of cylinders, one could use different spheres.Viren Shah GCSE Physics coursework Cylinder going down a ramp.

The Stiff Competition in the Mobile Phone Industry Case Study - 1

The Stiff Competition in the Mobile Phone Industry - Case Study Example Today, the largest players in the market include Nokia, Samsung, Apple, LG, and RIM. The features and functions of these phones have improved drastically in the last ten years. Most of the phones in use by 2005 were only equipped with basic functions of making receiving calls in addition to very few functions. However, stiff competition and research have greatly modified these phones over time. Many features like internet, navigation and phone size are continuously improved. In the same way, companies are very aggressive in their promotion strategies and are continuously searching for new markets. In terms of pricing, the present phone industry sees to present products for people in all walks of life. While phone prices have generally reduced over time, it is important to note that companies like Apple and Nokia produce very quality phones which are sold at slightly higher prices. Many of these additions have been realized after the launch of the iPhone (Wilkins, 45).

Experimental design on how to investigate the innate behaviour of Essay

Experimental design on how to investigate the innate behaviour of woodlice Introduction - Essay Example On the other hand, taxis behaviour is a behaviour in which an animal orients itself in an absolute direction in response to environment stimulus.2 Woodlice belong to the crustacean class. Most of these animals are terrestrial species and aquatic. It is believed that they exhibit an innate behaviour in that they tend to stay in wet and dark environment because they lack the characteristic waxy skeleton on their ex-skeleton like does most of the arthropods, thus tend to lose water easily when in dry conditions ()3. Woodlice are also good examples of organisms that orient themselves to humidity through kinesis. Woodlice also exhibit negative phototaxis. They have ocelli (light receptors). As a result, they do make directed movement away from illumination into the dark areas. They increase their locomotory activity in dry areas. However, this activity is decreased in humid conditions and for this reason they tend to accumulate in areas of high humidity.4 As indicated earlier, woodlice prefer wet and dark environment. Consequently, they increase their locomotory activities in dry areas and reduce their movement in humid areas. For this reason it would be expected that the number of woodlice will be greater int the more humid and dark areas. Then, the tray will be covered to exclude natural light and retain the humid moisture. The tray will be placed in a sheltered location free from direct sunlight. The lighting will be achieved through the use of a stand lamp placed at the same position and distance from the trays throughout the experiment. The distance will be reasonable to prevent transferring heat to the trays. Repeat the above procedures, but this time covering the tray with a perforated aluminium foil in order to create a dark environment, remove the stand lamp and then record the results after 30 minutes Table
