Thoughts On A Person/A Paper/A Promise Essays - British Poetry

Thoughts On A Person/A Paper/A Promise A Person/A Paper/A Promise is by far my favorite poem. It may not be the best poem ever written, but it expresses feelings and situations that I, as a human being and especially as a teenager, can relate to very deeply. The author describes a series of situations in the life of a person that resemble our own experiences or those of people we know. He manages to create a deeply affecting and poignant mood and compassionate, sympathetic feelings in the readers. The poem is divided into four stanzas, each of which narrates an episode in a boy's life. In each of the stanzas, the events and the people revolving around them are described, and in the following stanza, we read about how those events or people have changed and why. In every stanza, the boy writes a poem about a different subject, which we're led to believe is of major importance to him. The topics of his poetry change as he grows up, from his dog to the season, from his girlfriend to, in the final stanza, Absolutely Nothing. These changes show us how the boy's perspective of life constantly evolves. As a narrative poem, A Person/A Paper/A Promise has all the elements of a short story, including a rising action, which begins in the second stanza with his discoveries about how the people and things he took for granted, such as Santa Claus or Father Tracy, his priest, or sex, even, are not what they seemed at first. This rising action intensifies in the third stanza, when the kid, already grown-up now, is jaded, doing things because he has to, his family life being practically non-existent. This situation inevitably leads to the climax in the fourth stanza, when they boy writes his final poem, Absolutely Nothing, and commits suicide. Basically, over the years his life changes from perfect to meaningless, empty and chaotic, and he decides to end it. To me, this poem represents why we must rely on our inner strength when difficult situation arises and not give in to despair, because life is too precious a gift to waste it that way. I think that though it can touch anyone's heart, A Person/A Paper/A Promise has a stronger effect on people who, like me, have lost (or nearly lost) a loved one to suicide. Sometimes, we just don't understand how a person could kill himself. Throughout the poem, we learn about the kind of life the character's living and we sort of come to sympathize with him and understand his feelings. And yet, we can't help but feel impotent, seeing someone, even if he is fictional character, end his life by choice. This poem has made me aware of how I should make the best of what I have and live every instant to the fullest. And if I may ever find myself in a situation where I think I'm completely helpless, I'll know that life goes on and ending isn't the way to solve my problems. Poetry Essays

Finally, the third one is an academic guide to writing an evaluation essay on the spatial order in human visual perception. By reading this guide, you will be able to outline and seamlessly write a stellar essay. Without further ado, here are 10 facts on the spatial order in human visual perception: The human visual perception is far beyond our imagination. When we see our Earth’s surface, it appears that we can see nothing more than a few kilometers that lead up to the horizon. This is because the surface of the Earth literally curves out of sight after 5 kilometers.If the Earth’s surface were to be flat on the other hand, you would see a flickering candle flame even 48 kilometers away. In addition, our naked eye can see the Andromeda galaxy, which is located 2.6 million light-years away from Earth. The source of light that enters our retina travels from 1 trillion stars in the galaxy. Technically, we can see the color red with our naked eye, but in theory, it’s quite the opposite. Some scientists believe that the retina has receptors similar to that of an RGB (red, green, blue color spectrum) monitor. However, the eye’s retina can’t detect red shades. The so-called â€Å"red† receptor actually detects yellow-green hues whereas the â€Å"green† receptor detects blue-green colors or hues. These colors are then differentiated by our brain which tells us to see red colors. Selig Hecht, known for his remarkable work on human eye perception, made an accurate measurement of the human vision’s absolute threshold in 1941; i.e. the number of photons that must strike our retinas in order to stimulate the brain with visual awareness.The study that led to such a remarkable discovery was performed under ideal conditions where participants were allowed to adapt to total darkness; flashlights of 510 nanometer blue-green wavelength, acted as a stimulus, to which the human eye is most sensitive. It was concluded that our brain interprets vision when the retina is exposed to 5 14 photons. The human eye perception is limited to a certain degree. We are only able to see colors between 350 to 700 nanometer wavelengths. This is why we are not able to perceive ultraviolet and infrared colors. Ultraviolet colors fall in shorter wavelengths than 350 nanometers, whereas infrared colors are longer than 700 nanometer wavelengths. For example, when you take a look at bananas, you see the color yellow because they bounce off color wavelengths of 570-580 nanometers, when hit by full spectrum light. Have you ever asked yourself why you see things in 3D? Our brain is responsible for reconstructing images which let us experience life from a 3D perspective. This is because we have a pair of eyes that gives birth to a phenomenon known as Binocular Disparity – a slight difference in perspective between the left and right eye. Binocular disparity plays a vital role in giving depth to a scene. Convergence is another phenomenon which signals the brain to create depth of field, particularly when you are focusing on something close to your eyes. While we can see and perceive colors at the center in high resolution, our peripheral vision is very low in resolution – it’s blurry and nearly monochrome. However, we don’t actually see our peripheral vision as a monochrome image because our eyes and brain are quick enough to fill in the required details as soon as we become aware of this fact. It takes time for the human eye to perceive visual depth of a scene. The brain of a newborn child is not fully developed and must adapt to the new environment first before learning to construct a three- dimensional perspective. A study on infants has revealed that it takes a two months old baby to construct depth awareness of an image. Human visual perception is able to â€Å"adjust† to the dark by activating its own ‘night vision mode’. The neural pathways of the brain recalibrate themselves chemically to turn on scotopic vision circuits. These circuits are normally off during the daytime and require 20 minutes of darkness to be active. Scotopic vision circuits do not adapt to colors other than blue, as their receptors are blue-sensitive. You might have noticed how everything tends to take a bluish hue when you are trying to see in the dark. Ever thought why you can see the stars twinkling and shining at night? It’s because these receptors are very sensitive to even minor fluctuations in light. The brain is the main asset behind our visual perception. The eyes are merely tools to perceive light and transfer it to receptors that signal the brain to form images. The brain is, for a fact, the main component that constructs images and enables us to see perfectly. For example, our retina captures and interprets everything upside down, but still, we see everything the right side up. There are 100 million photoreceptors in each eye that enable us to see crystal clear images. However, there is only a million nerve fibers that act as a bridge to the eyes and brain. So, technically speaking, the resolution of our eye is not more than 1 megapixel. These facts will help you come up with your own topics and create masterpieces.
