Improving Concentration And Memory Skills

Improving Concentration And Memory Skills If you wish to improve your memory skills, i.e. your ability to remember information and recollect it when you so desire, it is imperative that you improve your concentration. Concentration requires you to focus intently on whatever you are trying to remember. Concentration enables you to: learn new facts recall information that you have already memorised It is obvious that you need to focus on the information to be learnt if you want to remember it. So you must improve your concentration to improve your memory. You cannot claim that your powers of concentration are weak and hence you suffer from a weak memory. Concentration is a mental skill. It can be developed by you, just like any other skill. There are several exciting ways in which you can boost your concentration power. Step 1: Power Your Brain If you really wish to improve your concentration, try the following tips and you will find a marked improvement in a relatively short time period. There have been several books that have been written on the subject of how the brain works and how you can use this knowledge to improve its functioning. In Train Your Mind, Change Your Brain, Sharon Begley explains that the structure and function of the adult brain is not set in stone. The connections between the neurons in your brain grow and change all the time. When you learn to play the guitar, study the human anatomy, read a book, practise the Chinese style of cutting vegetables, or develop a new habit, you are increasing the networking in the brain. As with any other muscle in the body, the more you use the brain, the better it becomes. You need to exercise a muscle regularly to develop it. In the same manner, you must exercise your brain regularly to develop and keep it in good shape. Your brain has the ability to change and grow all the time. This is a continuous process and does not happen overnight. With continuous and consistent effort, you can improve your brains ability to concentrate. Build into your daily regime the following habits: Mindfulness meditation: Begin by meditating for five minutes in the morning and for five minutes again at night before going to bed. If you do this everyday, you will notice that your power of concentration is improving. Mindfulness means to be aware or conscious. Meditation sharpens your focus and memory. Studies at Massachusetts General Hospital in Boston have proved that regular meditation creates changes in the physical structure of the brain by thickening the cortex. Then thickening of the cortex happens because of increased blood flow to that area. The cortex is that area of the brain that deals with the higher mental functions. So, meditation and memory are inextricably linked to each other. By meditating regularly, you improve your brains power to focus. It also helps bring clarity in your thinking. I found mindfulness meditation is the best way to meditate. In this way you have to do the reverse of other meditation methods commonly used. Here you will not try to empty your mind but you will try to fill your mind with as much as information you can. But it should be from the present only not from the past and the future. E.g. sit comfortably and try to focus on your breathing sound, listen the sound of it. Feel it, try to imagine that air going in and out. I mean make your all the senses/ perception busy enough in receiving information from the present moment. It will make busy your mind in the present passing movement and you will not get the time to wonder in past and future. And concentration is all about staying in present. You can do the same thing while eating, bathing, walking by making your senses busy in receiving the information in the present movement. Like what is the temperature of water you are using for bath or what are the ingredients of the food you are eating also try to analyse their quantity. Proper sleep: It is a well known fact that sleep contributes to the long-term consolidation of new memories (Nature journal, November 2006). Going by this, any new memories that are formed require enough sleep to enable the brain to organize and retain them. If a night has been slept in tossing and turning (if its due to an old mattress, throw it out and get a new one), the brain is not fresh and ready to face a new day of work. It is foggy and sleepy, and it will not function with clarity and sharpness. Its ability to retain anything will be reduced. Both concentration and memory will suffer because of poor sleep. To improve the quality of your sleep have a hot cup of milk before going to bed, remove stressful thoughts from your mind, darken the room, have warm shower, put on some light music and read a boring book. All these things are aimed at ensuring that you get a good nights rest. It will help your brain boost its energy levels. This in turn will lead to improved concentration. Eat healthier: There is a direct correlation between your diet and your concentration and memory. The nutrients and energy needed by your brain are supplied by the food you eat. The brain uses glucose, a sugar, as fuel, so your blood sugar needs to be regulated. To help improve your memory, cut back on fast foods which are high in saturated fats and salt, both of which block your carotid arteries. Such blockages reduce the supply of oxygenated blood to the brain. The focusing power of the brain is then diminished. Reduce your weight to the normal levels, for being overweight makes your physical body and your mental capacities sluggish. Eat foods that enrich your brain to help in improving its functionality. Brain foods include apples, bananas, dark green vegetables such as spinach, eggs, flaxseed, and fish, and some essential fatty acids like Omega -3. Drinking at least one liter of water a day per 23 24 kg of body weight will also help. To keep your blood sugar steady, take five or six small meals throughout the day. Limit your calorie intake to what is essential. Vitamins and other supplements: Brain enhancement supplements do not do much and can be avoided. Taking a multi-vitamin tablet everyday as a supplement does help. It may fill in the lacuna created by any kind of vitamin deficiency in your diet. Cod liver oil capsules, Vitamin B and vitamin C tablets help in supplementing the vitamins that you get from your regular diet. Vitamins are essential for the proper functioning of your brain. Brain games: You need to play the games that ask for greater focus. These should be played often to improve your concentration levels. This is because the brain becomes better at whatever it exercises on a regular basis. By playing those games that require concentrated effort, the brains ability to focus increases. Step 2. Optimize your Environment: A proper environment, conducive to studies, also helps in improving your concentration. A Study Area: It is good to have a designated spot for studying. You will get in the habit of studying there. Make sure its not the bed that you use for studies, for the bed relates to sleep. Have a desk in a quiet and secluded place away from noise to enable you to concentrate. Try Different Coloured Lights: Recent studies indicate that the use of a green light bulb in the study lamp improves concentration. You could try this out to see if it works for you. Red light is also supposed to improve concentration and memory. You may also decorate your study area with artifacts and items which are red in colour and see whether this helps in improving your concentration. Remove Distractions: Radio, television, and telephone are all distractions. They should be switched off during your study time. This will help you focus. Make sure that when you study, you are not disturbed by friends who call or drop in unexpectedly. Your study time should be clear to you as well as others. By demarcating your study hours, you will prevent the distractions that otherwise eat into your time. Use Time Boxes: For a particular portion of study, set a reasonable time limit. If you wish to learn a new chapter, set forty minutes for reading it and another twenty minutes for learning it. You should be able to complete the chapter in one hour. By doing this, you ensure that there is a deadline to be met and this helps you to focus on the work. Stay Motivated: To stay motivated you can promise yourself a reward at the end of a certain period of focused studying. For example, you may tell yourself that after a couple of hours of study, you will have earned the reward of watching your favourite T.V. show at night. Take a Regular Break: Every hour, take a five minute break, to prevent your energy levels from lagging. You should get up from the chair, walk a bit and stretch your legs. Have a glass of water or a light snack. Do some eye exercises to relax your eyes. Change your Breathing: Change your breathing to activate your alpha waves. Switch your breathing pattern to deeper and slower. This helps your brain to switch to alpha waves, which mentally prepare your brain to concentrate on new facts. The alpha waves bring your mind to readiness to learn new facts. This is the cool and relax state of mind. Any learning requires concentration. Without focusing on the information, the brain will not be able to learn or remember. If your brain wanders, it will not recall a lesson. So concentration is a must for learning and retaining. Improvement in concentration will lead to improvement in the memory since learning, remembering and recollecting are all inter- related. If you have not learnt, how will you remember? Hence, improve your concentration and this will lead to an improved memory.

Our Toughest Struggles in Life Can Be with Ourselves Essay

In our life, struggles are everywhere. If we want to be successful, we will have to strive hard. Just as an old Chinese saying goes, â€Å"There won’t be the fragrance of calyx canthus if the flower doesn’t go through the chilly winter.† Only after we undergo different kinds of hardships, can we achieve what we aim at. Therefore, we must get ready to face the toughest struggles and try to deal with any ups and downs calmly and bravely. When I was a little boy, I always dreamed of getting a nice toy like the one my friend Henry had. One day, I told my mother about that, hoping she would buy me one. However, she just ignored my idea, encouraging me to save money and buy one for myself. At first, I was so disappointed and frustrated that I got very angry with her. Later, I calmed down and thought what she suggested might as well be a good way to accomplish my wish. So I spared every cent I could in my daily life until finally one year later I accumulated enough coins and got that fancy stuff. During that year, I overcame numerous difficulties like killing the desires of buying candies, pulling myself back from snack bars, restraining myself from watching too many movies, etc. It was really too much for a ten-year boy. Nevertheless, my mother was right – I achieved what I had always wished for and trained myself the ability to handle any tough struggles in my later life. Two years ago when I first came here, I encountered another unimaginable problem in my life – I understood little in class just because of my poor English. I was depressed and sighed in despair all the time. It was my mother and teachers who inspired me and gave me a lot of encouragement. They told me that difficulty was everywhere and it could accompany anybody anytime. As long as we got ready and took actions, nothing was impossible. From then on, I got up early every day to practice speaking English, listening to English and reading English. Besides, whenever I was free, I went to various markets to practice speaking English with native speakers. Success always shows appreciation for those who make great efforts. Nowadays, I am able to understand most of the lessons in class and express myself in English most of the time in my daily life. What I get from my own experience is that life is not always filled with  flowers and easiness. The road of our life is made up of struggles and success. How successful we are depends on how much endeavor we are willing to undertake. Accordingly, we need to prepare for any toughest struggles in life as they can come up anytime.

Assumption of Douglas Mc Gregor Theory X and Theory Y

In the 1950s, Douglas McGregor (1906-1964), a psychologist who taught at MIT and served as president of Antioch College from 1948-1954, criticized both the classical and human relations schools as inadequate for the realities of the workplace. He believed that the assumptions underlying both schools represented a negative view of human nature and that another approach to management based on an entirely different set of assumptions was needed. McGregor laid out his ideas in his classic 1957 article The Human Side of Enterprise and the 1960 book of the same name, in which he introduced what came to be called the new humanism. McGregor argued that the conventional approach to managing was based on three major propositions, which he called†¦show more content†¦The major propositions of Theory Y include the following: 1. Management is responsible for organizing the elements of productive enterprise-money, materials, equipment, and people in the interests of economic ends. 2. People are not by nature passive or resistant to organizational needs. They have become so as a result of experience in organizations. 3. The motivation, potential for development, capacity for assuming responsibility, and readiness to direct behavior toward organizational goals are all present in people-management does not put them there. It is a responsibility of management to make it possible for people to recognize and develop these human characteristics for themselves. 4. The essential task of management is to arrange organizational conditions and methods of operation so that people can achieve their own goals by directing their efforts toward organizational objectives. Thus, Theory Y has at its core the assumption that the physical and mental effort involved in work is natural and that individuals actively seek to engage in work. It also assumes that close supervision and the threat of punishment are not the only means or even the best means for inducing employees to exert productive effort. Instead, if given the opportunity, employees will display self-motivation to put forth the effort necessary to achieve theShow MoreRelatedThe Theory X And Theory Y Essay1479 Words   |  6 Pagesobtain satisfaction from performing their duties well.

Essay on The Use of the Submarine During the American...

The Use of the Submarine During the American Civil War I have always been an American history buff. I was aware that the first use of the Submarine during war was during the American Civil War. Since learning this fact, I had become, in a sense, amazed with submarines - thus, I have become rather interested in them. I found this paper as a good chance to learn more, a lot more, about early submarines and the evolution of them. With the ability to sink both large and small warships with the same percent chance, the value of the submarine is great because it was much cheaper to build than larger warships in the late 19th and early 20th century. The submarine has a way of concealing itself that is denied to the torpedo boat by†¦show more content†¦The side propellers would then be set in motion, allowing the submarine to sink to a required depth. The great thing about this boat is that, should there be a failure of the engine, the boat, from its own buoyancy, would rise to the surface. Experiments were conducted in 1910 with he British submarine D1, the largest in the British Navy. These experiments were successfully carried out. What were these experiments. Well, the D1 was able to maintain communication while submerged. The D1 replied from below the surface. The tests were conducted at a level deep enough so that the periscope would be kept just above the water line and the rest of the boat was submerged. The periscope was half way up the mast. To compare the American technology to that of the European world, in 1913, the largest submarine built for the United States Navy was just short of 500 tons displacement submerged. The submarine proposed for the Russians Czars Navy was to be nearly 10 times as great, 5,400 tons of displacement submerged. The tendencies in the construction of early submarines was mainly toward an increase in their displacement. In 1913, the idea to equip submarines with defensive and protective weapons, in addition to torpedoes, came about. These guns could be used in defense against enemy submarines or even against enemy planes, to give you an example of their necessity.Show MoreRelatedWhy Was The Submarine So Pivotal?

The Scarlet Letter, By Nathaniel Hawthorne - 1593 Words

Rockwell Test HRC = 100 – d /0. 002 HRB = 130 – d /0. 002 Where d = depth of the indentation 3. Brinell Test BHN = Applied force / curve area of indentation P / D/2 [D – (D? – d? )] = P / Dh WhereP = applied load (kgf) D = diameter of steel ball (mm) d = diameter of resulting indentation (mm) h = depth of indentation (mm) = ? [D – (D? – d? )] APPARATUS 1. Set of Vickers Hardness Test Machine . Set of Rockwell Hardness Test Machine 3. Set of Brinell Hardness Test Machine SPECIMENS Mild steel, carbon steel and ASSAB steel A) VICKERS HARDNESS TEST From this method square shape pyramid diamond 136 ° was press to surface of metal using some load (5kgf until 120kgf) under certain time (15 sec) and lastly the load will release. Square shape corner on the metal surface will be used. To obtain the value of hardness, Vi ckers Hardness Number (VHN) is calculated as below: VHN=Mass of the loadSurface area of depression =2PSin136 °2d2 =1. 854Fd2approximately Where, P=applied forcekgf d=d1+d22 B) ROCKWELL HARDENESS TEST This method has 2 main scales which are: a) Scale B, concavity is a steel ball (1. 58 mm? ) and load using is 100 kgf. b) Scale C, concavity is a cone diamond having corner 120 ° and load is 150 kgf. Rockwell hardness (HR) can be calculated as equation below: HRC=100-d0. 002 HRB=130-d0. 002 Where d=concavity C) BRINELL HARDNESS TEST From brinell hardness test, the harden steel ball has good diameter, D under the load and certain time will be use to get diameter concavity effect,d.

The specimen (Mild Steel) is put on the anvil of the Vickers hardness machine precisely. 2. The sample is focused until the lines on the surface of the sample can be observed clearly. 3. The focal lens of the microscope is turned to the indenter. 4. The indenter is then pressed into the sample. 5. The test force is maintained for a specific dwell time of about 15 seconds. 6. The indenter is removed when the dwell time is complete. 7. The square shape is appears on the surface of the sample. . The indenter is then turned back to the focal lens. 9. The size of the indent is determined by measuring the two diagonals of the square indent. 10. Step 1 to 9 is repeated for five times by using the same sample but at different part of the sample. 11. Step 1 to 10 is then repeated by using different sample, which is carbon steel. 12. All the readings taken are recorded in a table. b) Rockwell Hardness Test 1. The sample of ASSAB steel is placed exactly on the anvil. 2. The anvil is wound slowly until the LED begins moving to ‘SET’ and the test is started automatically. 3. The indenter moves down into the position of the part surface of the sample. 4. The load is then applied on the sample for a specific dwell time of 15 seconds. 5. The readings taken are recorded from the indenter machine. 6. Step 1 to 5 is repeated for five times by using the same sample but at different part of the sample. 7. Step 1 to 6 is then repeated by using different sample of carbon steel. 8. All the readings taken are recorded in a table. c) Brinell Hardness Test 1. The sample of mild steel is placed accurately on the anvil. 2. The anvil is wound slowly until the edge of the indenter touches the surface of the specimen. . A handle on the right side of the testing machine is lifted slowly until the gauge shows 1000kgf. 4. The indenter is pressed on the sample by an accurately controlled force for about 15 seconds of dwell time. 5. The indenter is removed slowly after 15 seconds, leaving a round indent in the sample. 6. The diameter of the indent is taken by measuring two diag onals of the round indent by using a portable microscope. 7. Step 1 to 6 is repeated for two times for the same sample but at different portion of the sample. 8. Step 1 to 7 is repeated for another sample of carbon steel.

From this experiment, we can conclude that the higher the Vickers Hardness Number (VHN) of a specimen, the harder the specimen is. We had being tested two specimen which is Carbon steel and Mild steel for Vickers hardness Test. Carbon steel has an average VHN of 225. 6 while the mild steel has an average VHN of 119. 2. This means that carbon steel is harder compared to mild steel. 2. The carbon steel is harder than mild steel because there is a presence of carbon atoms within the atoms of the structure. When the external force is applied, the carbon atoms prevent the atoms in the structure into sliding over and slipping. b) Rockwell Hardness Test 1. From the Rockwell hardness test, we can conclude that the higher the HRC number of a specimen, the harder the specimen is. . ASSAB steel is a type of alloy steel and thus its composition is much different than that of carbon steel, causing it to possess higher hardness compared to carbon steel. 3. From the result obtained, ASSAB steel has an average HRC number of 57. 27 where as carbon steel has an average HRC number of 27. 12. This mean that AASAB steel is harder co mpared to the high quality carbon steel. c) Brinell Hardness Test 1. For two specimens which carbon steel and mild steel is being tested with brinell hardness test. The BHN values are obtained. The values are depends on the diameter of the indentation caused. 2. We can conclude that the higher the value of the BHN, the harder the specimen is. 3. From the results, carbon steel has an average BHN of 212 while mild steel only as an average BHN of 99. This confirms that carbon steel is harder than mild steel. 4. Furthermore, the values of BHN obtained might be not accurate because of the limitation that caused human errors. It is difficult for the observer to note the exact diameter of the indentation through the microscope. CONCLUSION In conclusion, from the results we obtained, it is conclude that ASSAB steel is the hardest material, followed by carbon steel and then mild steel. The hardness of the steel is mainly affected by its composition and percentage of carbon. Carbon steel is absorbed energy is lower than the mild steel. Carbon steel is a brittle material compared to mild steel because of the higher percentage of carbon present in the steel. Thus, fractures almost immediately upon sudden impact. 2. Charpy impact test INTRODUCTION The Charpy Impact Test is the most commonly used test to determine material’s resistance to the impact or sudden fracture where a sharp stress raiser is present. Toughness is a measure of the ability of a material to absorb energy up of fracture. For dynamic (high strain rate) loading conditions and when a notch is present, notch toughness is assessed by using an impact test. Material that experiences very little or no plastic deformation upon fracture is termed brittle whereas material that experiences great deformation upon fracture is termed ductile. The fracture surfaces for brittle material, which has low-energy impact failure, are generally smooth, and in metals have a crystalline appearance. But for ductile material which has high energy fracture, has regions of shear where the fracture surface is inclined about 45o to the tensile stress, and they have in general a rougher, more highly appearance, called fibrous fracture. THEORY 45? 2 mm 45 mm 10 mm 30? Figure 1 45? 2 mm 45 mm 10 mm 30? Figure 1 In Charpy impact test, the specimen are arrange as shown in the above picture and every specimen is prepare will has a notch at the centre of the specimen and the hammer will clout at the region of the notch i. e. stress concentration point. The hammer is release from a specific high which the initial energy having by the hammer is 300J. The scale will show the energy absorbs by each specimen after the experiment and it is recorded. APPARATUS Charpy testing machine SPECIMENS Mild steel and carbon steel PROCEDURE 1. Mild steel and Carbon steel is used in this test. 2. The load was applied as an impact blow from a weighted pendulum hammer that was released from a cocked position at a fixed height. 3. The specimen was positioned at the base of the machine. 4. Upon release, a knife-edge mounted on the pendulum strikes and fractures the specimen at the notch, which acts as a point of stress concentration for this high velocity impact blow. 5. After the weighted pendulum hammer has swung to its original position, the specimen was removed from the vice and its fracture surface was observed. RESULT Specimen| Energy Absorbed / J| Mild Steel| 299| Carbon Steel| 30| DISCUSSION 1. In this experiment, we can see that the energy absorbed by mild steel (299J) is higher compared to the energy absorbed by carbon steel (30J). This shows that carbon steel is a more brittle material and mild steel is a more ductile material. 2. According to the result which energy absorbed by mild steel is higher and it is more ductile. In addition, carbon steel is a brittle due to presence of the carbon atoms in steel. The presence of these carbon atoms provide resistance for plastic deformation to occur by preventing atoms in the steel to slip and slide over each other. The high percentage of carbon atoms reduces the ability of the steel to absorb energy upon impact. 3. As we observe the experiment that we had done in lab, the carbon steel breaks almost immediately when subjected to sudden impact whereas the mild steel shows only deformation and did not fracture. 4. Besides the area where the carbon steel fractures is shinny and smooth which shows that it fractures without much deformation. 5. The diagram below shows fracture surface of the mild steel. 6. The diagram below indicates the fracture surface of the carbon steel. Based on the results, it is clear that the ductility of mild steel is higher than carbon steel. The presence of carbon in carbon steel has minimized its ability to absorb energy from the impact. CONCLUSION In conclusion, we can conclude that mild steel has a high level of ductility than carbon steel. Mild steel is tougher than carbon steel. REFERENCE 1. William F.

Drama Studio Essay Example For Students

Drama Studio Essay I am going to be playing the character of the Angel. Throughout the play, I must ensure that the duality of my character is made clear to the audience; when addressing Joe I must speak calmly, in a relaxed, smooth tone to try and lull him into thinking I am there to help him. This I will do by extending words and syllables within each sentence, usually the last word. My Laban Effort, system of movement, at this time will be floating: a sustained, slow speed; flexible space usage, not moving in any particular direction, and a light idea of weight, so I am not dragging my feet. When addressing Hughbert in the presence of Joe, I will give often give an idea of suppressed rage; Hughbert makes my plan harder to implement, but I must remain calm and in control in the presence of Joe. To do this I will speak behind gritted teeth. When Joe leaves the room however, the darker side of my character is revealed. I suddenly speak in a much sterner manner, enunciating each syllable much more sharply. I will also raise my voice, and will be far less smooth, speaking in a single pitch, rather than varying the pitch as I do when with Joe. My Laban Efforts will become pressing: still at steady pace, but I will be more direct in my movements, more purposeful. I will also move with more apparent weight, to signify power. These are the primary three ways in which I shall act during the play. The only real variation from this on my characters attitude is at the end. My pitch will be subtly higher, and I will speak quicker. This is because I no longer have to pretend to be nice, as I have Joe where I want him. I will have a greater urgency, and be more taunting, speaking faster than before. The play Macbeth was intended to be a realistic play. Although when performed, it is intended to include all relevant props and scenery, effects such as the dagger of the mind and other such supernatural events can only be represented, not shown as the characters are supposed to see them in the play. There would be few lighting effects in the time when this was originally performed, as electricity was not available and all plays were performed open-air during the daytime. The fourth wall, the divide between actors and audience would be around at the time, with no audience interaction, and although soliloquies would be to the audience, they are not speaking to the audience within the confines of the play, merely speaking their thoughts aloud. Macbeths genre is tragedy, as there are no aspects of comedy at all. It is a very morbid, macabre play in which many people die. Wake Up is partially realistic play, as we are using appropriate props such as a pill bottle, fake pills (tic-tacs) and a makeshift sofa using chairs and old curtains. Props are not mimed within the production. On the other hand, due to the confines of the Drama Studio, there will be no scenery. We will instead use differentiation in lighting to help the audience distinguish between dreams and reality. The surreal aspect of the play may mean that it is more stylistic than realistic, as we do not have access to extensive amounts of scenery or props. The real life sequences will be predominantly realistic, whereas the dream sequences will be stylistic, as befits the idea of a dream. The term realistic refers to a focus on the reality of the characters, but not perfectly recreated with every prop as if it were real life; that is what a naturalistic play does, mimics nature. The term stylistic is the opposite of naturalistic; things are mostly symbolic, so that the idea of something is put across but not shown visually. .u502a1bd3d283f9a78571d15e405d1709 , .u502a1bd3d283f9a78571d15e405d1709 .postImageUrl , .u502a1bd3d283f9a78571d15e405d1709 .centered-text-area { min-height: 80px; position: relative; } .u502a1bd3d283f9a78571d15e405d1709 , .u502a1bd3d283f9a78571d15e405d1709:hover , .u502a1bd3d283f9a78571d15e405d1709:visited , .u502a1bd3d283f9a78571d15e405d1709:active { border:0!important; } .u502a1bd3d283f9a78571d15e405d1709 .clearfix:after { content: ""; display: table; clear: both; } .u502a1bd3d283f9a78571d15e405d1709 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u502a1bd3d283f9a78571d15e405d1709:active , .u502a1bd3d283f9a78571d15e405d1709:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u502a1bd3d283f9a78571d15e405d1709 .centered-text-area { width: 100%; position: relative ; } .u502a1bd3d283f9a78571d15e405d1709 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u502a1bd3d283f9a78571d15e405d1709 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u502a1bd3d283f9a78571d15e405d1709 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u502a1bd3d283f9a78571d15e405d1709:hover .ctaButton { background-color: #34495E!important; } .u502a1bd3d283f9a78571d15e405d1709 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u502a1bd3d283f9a78571d15e405d1709 .u502a1bd3d283f9a78571d15e405d1709-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u502a1bd3d283f9a78571d15e405d1709:after { content: ""; display: block; clear: both; } READ: Twelfth Night Essay ThesisThings such as imaginary doors are evident in the dream scenes, as there is supposed to be no concept of normal human reality, making this side of the play very stylistic. We will perform this with the fourth wall, defined above, in all scenes excluding scene 5, in which the audience is referred to; Joe is asked to pick out the member of the audience (all of whom are beautiful women as far as Joe is concerned) to have sex with behind an imaginary door. Wake Up is predominantly a tragedy, but there are a few light-hearted areas as well. The scene where Junior is suggesting potential girlfriends has a faster pace than other scenes, as it has a more comical overtone than most of the rest of the production In conclusion, these plays are both different, yet still have similarities. They are written around 400 years apart, and set almost 1000 years apart. Despite this, there are still similarities in the underlying ideas. The plots are both tragic, and follow the same general themes of deception and death. The characters have similarities in motive, it is generally only their methods which alter. The style of Macbeth is realistic, whereas Wake Up is more stylistic, due to the limitations of the resources at hand and time scale.
