Sacrifice as a proof for emotions Essays

Sacrifice as a proof for emotions Essays Sacrifice as a proof for emotions Essay Sacrifice as a proof for emotions Essay 1. Making sacrifices  The author looks at this theme from several viewpoints: to what extent are we ready to give to protect the ones we love, the difference between sexes (women seemingly being less selfish), also at sacrifice as a proof for emotions. Also, the play focuses on often very relative differences between sacrifice and duty.  2. Independence and freedom  The play manifests necessity of independence in life as well as in any relationship. Before everything else, we are human beings, not somebody elses spouses, children or dolls. Before duties and responsibilities that we have for others we have responsibilities to ourselves. Ibsen analyses the difference between the view that the individual has of himself and what his fellow humans opinions of him are, asserting that it is more important to gain self-respect than to suffice with fulfilling others expectations that may be in conflict with ones own. 3. (im)possibility to love truly  This is one of the problems of the modern life that are focused on in The Dolls House. The characters of this play marry (form relationships) because of money, or to feel useful, or just because they feel like they have to. Relationships that are commonly approached the most important in life, form between strangers, and it is unlikely to love somebody who is actually a stranger. What should be love reveals to be a game of doll and the doll master (Nora and Torvald) or a compensation of past failures (Christine and Krogstad). This problem is strongly linked to another theme in this work- 4. Alienation and loneliness  This is another modern calamity. Each of Ibsens characters is in some way or another detached from others and does not see the real meaning of his or her life. As it is shown at the end, Helmers only considered their marriage a proof that they have a goal in their lives; Krogstads and Christines unification was a desperate step, hoping that two unhappy, unsuccessful people will do better together. Nora, the central character, has been alienated from her life, even from her true self, for all her lifetime. She has lived like in a trance, accustomed to the role of somebody elses inferior. 5. Greediness and the exaggerated importance of money  Even though quite a lot of the problems discussed in the play arise from characters tendency to overestimate the importance of money, valuing that higher than feelings (Torvald, once Krogstad), I consider this only a minor theme. The reader has to re-evaluate his/her own attitudes, though.  6. Marriage  The view upon marriage that Ibsen has in this play is common now but was provocative at the time it was written. Here, marriage is revealed to be full of alienation even when both spouses have supposedly chosen it themselves (theoretically, Nora was not under pressure to marry Torvald). Ibsen stresses that marriage should be based upon equity; Noras sacrifice could not be compensated with the small sums of money that Torvald gave her (actually buying her physical love). A married couple should continue being individuals, not become each others supplements. 7. Human, particularly women, rights  8. Mens tendency to treat women as dolls  Ibsen notes the importance for each person to have the opportunity to explore and expose ones true identity. The play contains a powerful protest against role- playing that is often required and seemingly obligatory in the society. It shows how the individual can actually lose his own self (or never see a need to get to know who he really is and what he really thinks), pursuing the role that he mistakenly recognises as his own identity. Ibsen stresses that before being or becoming anything else, we are all equal human beings. As prejudices about the role that has to be played in family, are commonly afflicting women, and the main character is Nora, the play is more focused on women rights to their own lives, opinions and identities. The play also focuses on the theme of woman being a mans doll, which is itself nothing modern. This has been a common phenomenon, almost a tradition, established with the harems and polygamy before our era, and more than accurately proceeded until nowadays (one of the most popular striptease clubs in Riga is called Dolls). The play does not show the lasting nature of this tradition, but exposes it vividly and horribly enough.  Characters  Nora Helmer  Throughout nearly all the play, Nora demonstrates herself as a naive, a bit silly, inexperienced and obedient wife to her husband Torvald. She can hardly be referred to as a person, for there is nothing personal in her character all she is is what others, her father and Torvald, have made of her. However, during the play, Noras awareness of both herself and the world around her increases. She becomes able to recognise that her relationship with Torvald puts her in a position of a pet or a doll. Nora notes that Torvald, whom she has always assumed to be a good person (and wonderful husband), is actually mean- he is determined to sack Krogstad only because he assumes that Krogstads familiarity towards him might harm his reputation. Noras illusions of her husband and marriage quell completely when she sees Torvalds behaviour after he has read the letter informing of her fraud. Unexpectedly, Nora finds strength in herself to give up the lifestyle that she has been taught to pursue since her very childhood. Her sudden courage lets the reader anticipate other qualities that Nora might possess but has never been able to show. Torvald Helmer  Complete possessiveness over Nora and superior attitude are both observable in every Torvalds action that is linked to his wife. Torvald enjoys having total control, and not only over Nora (he gives Christine directions about knitting). At the same time, Torvald is a superficial, narrow-minded person (Nora rightly assumes that he will not love her when she will have grown old- Torvald can only feel physical attraction). He would not be able to be present at his best friends deathbed because of his dislike of weak, dying people. Torvald is unable to feel overwhelming emotions (perhaps except rage), to give to others. Setting  All the action of the play is set in the Helmers family house, which is situated in the centre of a city. The rooms are tastefully and pleasantly, but not very expensively furnished (Helmers have not been that financially secure). The house is cosy and warm, with a fireplace. The events take place in winter, beginning on Christmas Eve.  Vocabulary  Spendthrift, macaroon, skylark, precarious, imprudent, zealously, unassailable, obstinate, rogue, incubus, prompt, wedlock, heedless, elapse, variegated, tremendous, consternation.  Yet, I noticed some more specific vocabulary- all the names that Torvald has for Nora that reveal the nature of their relationship and Torvalds possessiveness: Both of these works deal with individuals role in society and more specifically, family. In Metamorphosis, Gregor is his familys material supporter, putting off dreams of his own; in A Dolls House, Nora Helmer is her husbands sexual plaything, not allowed to have her own will or identity. Both these characters leave their families. Nora realises that both her and her family members are too involved in a game of dolls and masters to be able to develop as human beings; Gregor, already turned into an insect, sees that his role in family as the sole supporter has actually allowed them to immerse in a state of artificial, prolonged apathy. There is one important difference between the two works- Ibsen has taken a position from which Noras decision at the end of the play seems entirely correct; Kafka, however, looks at the situation not only from Gregors, but from several viewpoints. In Metamorphosis, none of characters is completely wrong or correct because the author would have wanted it; the reader may decide by himself. However, the most significant mutual feature of these works is even more vital and it lies in their point of view, in the sense with which they are written- alienation, separation, inability to integrate oneself not only in the world, but also even in ones family. Both pieces main characters are in disharmony even with themselves. This makes both Metamorphosis and A Dolls House topical and substantial for the society- the main characters are common people going through the most serious and widespread problems of our time. Commentary  The play shows how easy it is to lose oneself in relationship. Others expectations may seem more important than preserving ones own self.  However, the play focuses on a rather extreme situation- in the Helmer family, Torvalds expectations to Nora are more like demands- to obey, to be his little squirrel, his doll. This is what lets us evaluate the whole situation and be quite certain that Torvalds actions are demagogical and harmful to Nora. In the real life, on the other hand, adaptation is a normal part of a lasting relationship, and the demands that are made are often logic. When my mother demands me to clean my room, I obey. I dont say that she hinders my development and oppresses my identity even though cleaning my room is an alternative to something relatively more valuable like writing a story. If I agree to clean my room, it does not make me anybodys doll, because I know about the sacrifices my mother has made or tried to make to bring me up and is still maki ng. But there are more difficult situations in life. For example- my father has four children and I am the eldest. I would like to try and find some interesting occupation connected with art or literature (both are my hobbies, and I have had enough success to keep going and see some perspectives for myself). Then again- these are not jobs that let one earn much, and I have good marks in nearly any subject. I am not sure of what will become of the other children. Further, my younger half-brother is invalid, some disease that I had, too, but in my case, the doctors did notice. With my brother, it was too late, and some parts of his brain had been damaged. Now, he is six, but he does not talk and has co-ordination problems. And basically, nothing can be done about it here in Latvia. I know he could get better help abroad, but that would cost very much. I feel like I owe him. It was mere chance that I was saved and he was not- sometimes I am not sure if he has any life at all, or that he will have. I have decided to get a proper education and enter a proper high school, and then find an occupation that would perhaps bore me to death, but give me chance to help my brother. And not only him- it might happen that I have a bunch of people to take care of, anything might happen.  But it might end up with them using me (approaching me as a money- making mechanism as Nora was approached as a doll) or feeling like they owe me. And I would partly have to give up my own true identity, too, to an extent, to do this money job. I do not know what I should do and what would be the right choice. But I am quite certain about what I will do. What seems to me uninteresting in this work is that it is so easy to see what the characters should do, to distinguish right from wrong. Of course, at that time the bond of marriage was considered more important, more sacred, than it is now, therefore the play could be received in a more disunited way- that Noras decision was incorrect. However, I dislike that Torvald seems so absolutely wrong (and a bad person besides), while Nora looks unquestionably correct. Ibsen has made everything seem so obvious- he does not remind the reader of motherless children, but focuses on Noras romantic, poetic quest for freedom. It makes the play too one-sided. However, the one-sided view does not deter the reader from paying more attention to another tendency in our society- the willingness with which individuals are ready to give up control over their lives, handing it over not only to their family members like Nora, but also to strangers (for example, reality shows; the excessive amounts of personal information often available to state; sadomasochism). I think that this fear of responsibility points to serious identity problems- so widespread that they have actually become problems of the whole society.

Solar Radiation and the Earths Albedo

Solar Radiation and the Earth's Albedo Nearly all of the energy arriving on planet Earth and driving the various weather events, oceanic currents, and distribution of ecosystems originates with the sun. This intense solar radiation as it is known in physical geography originates in the sun’s core and is eventually sent to Earth after convection (the vertical movement of energy) forces it away from the sun’s core. It takes approximately eight minutes for solar radiation to reach the Earth after leaving the sun’s surface. Once this solar radiation arrives on Earth, its energy is distributed unevenly across the globe by latitude. As this radiation enters the Earth’s atmosphere it hits near the equator and develops an energy surplus. Because less direct solar radiation arrives at the poles, they, in turn, develop an energy deficit. To keep energy balanced on the Earth’s surface, the excess energy from the equatorial regions flows toward the poles in a cycle so energy will be balanced across the globe. This cycle is called the Earth-Atmosphere energy balance. Solar Radiation Pathways Once the Earth’s atmosphere receives shortwave solar radiation, the energy is referred to as insolation. This insolation is the energy input responsible for moving the various Earth-atmosphere systems like the energy balance described above but also weather events, oceanic currents, and other Earth cycles. Insolation can be direct or diffuse. Direct radiation is solar radiation received by the Earth’s surface and/or atmosphere that has not been altered by atmospheric scattering. Diffused radiation is solar radiation that has been modified by scattering. Scattering itself is one of five pathways solar radiation can take when entering the atmosphere. It occurs when insolation is deflected and/or redirected upon entering the atmosphere by dust, gas, ice, and water vapor present there. If the energy waves have a shorter wavelength, they are scattered more than those with longer wavelengths. Scattering and how it reacts with wavelength size are responsible for many things we see in the atmosphere such as the sky’s blue color and white clouds. Transmission is another solar radiation pathway. It occurs when both shortwave and longwave energy pass through the atmosphere and water instead of scattering when interacting with gases and other particles in the atmosphere. Refraction can also occur when solar radiation enters the atmosphere. This pathway happens when energy moves from one type of space to another, such as from air into water. As the energy moves from these spaces, it changes its speed and direction when reacting with the particles present there. The shift in direction often causes the energy to bend and release the various light colors within it, similar to what happens as light passes through a crystal or prism. Absorption is the fourth type of solar radiation pathway and is the conversion of energy from one form into another. For example, when solar radiation is absorbed by water, its energy shifts to the water and raises its temperature. This is common of all-absorbing surfaces from a tree’s leaf to asphalt. The final solar radiation pathway is a reflection. This is when a portion of energy bounces directly back to space without being absorbed, refracted, transmitted, or scattered. An important term to remember when studying solar radiation and reflection is albedo. Albedo Albedo is defined as the reflective quality of a surface. It is expressed as a percentage of reflected insolation to incoming insolation and zero percent is total absorption while 100% is the total reflection. In terms of visible colors, darker colors have a lower albedo, that is, they absorb more insolation, and lighter colors have a high albedo, or higher rates of reflection. For example, snow reflects 85-90% of insolation, whereas asphalt reflects only 5-10%. The angle of the sun also impacts albedo value and lower sun angles create greater reflection because the energy coming from a low sun angle is not as strong as that arriving from a high sun angle. Additionally, smooth surfaces have a higher albedo while rough surfaces reduce it. Like solar radiation in general, albedo values also vary across the globe with latitude but Earth’s average albedo is around 31%. For surfaces between the tropics (23.5Â °N to 23.5Â °S) the average albedo is 19-38%. At the poles, it can be as high as 80% in some areas. This is a result of the lower sun angle present at the poles but also the higher presence of fresh snow, ice, and smooth open water- all areas prone to high levels of reflectivity. Albedo, Solar Radiation, and Humans Today, albedo is a major concern for humans worldwide. As industrial activities increase air pollution, the atmosphere itself is becoming more reflective because there are more aerosols to reflect insolation. In addition, the low albedo of the world’s largest cities sometimes creates urban heat islands which impacts both city planning and energy consumption. Solar radiation is also finding its place in new plans for renewable energy- most notably solar panels for electricity and black tubes for heating water. These items’ dark colors have low albedos and therefore absorb nearly all of the solar radiation striking them, making them efficient tools for harnessing the sun’s power worldwide. Regardless of the sun’s efficiency in electricity generation though, the study of solar radiation and albedo is essential to the understanding of Earth’s weather cycles, ocean currents, and locations of different ecosystems.
