Essay on Analysis of Countee Cullens Yet Do I Marvel

Analysis of Countee Cullens Yet Do I Marvel Poetry is often meant to be smooth, flowing, pleasing to the ear and the mind. To achieve this effect, many poets use different poetic techniques to help convey the meanings of their poetry. In the sonnet, Yet Do I Marvel written by Countee Cullen, many different features of poetry is used. In this essay, I will discuss the relationship between the meanings and the theme Cullen tries to convey in his sonnet and the techniques of metaphors, both religious and non-religious, allusions to Greek mythology, different rhyme schemes and repetition that he uses. In his sonnet, Cullen uses strong themes of religious metaphors while adding many non-religious metaphors at the same time.†¦show more content†¦Allusions of Greek mythology provide excellent images for Cullen?s questions as the mythology seem like metaphors themselves. ?Make plain the reason tortured Tantalus / Is baited by the fickle fruit,? (Lines 5 ? 6). In Greek mythology, Tantalus was one of Zeus?s non-immortal sons who became immortal by dining with the Gods. However, after telling his friends the secrets of the Gods, he was punished by being place up to his chin in water that he could not drink, and with fruit in sight that he could not reach. Cullen uses Tantalus as an allusion to question God about why humans are given grace of the Gods/God, but are kept from the ?fruit? of actually being divine-beings. By saying, ?Make plain?, he wishes for God to tell him in terms that he could understand. Again, the speaker makes clear his position relative to that of God. ?declare / If merely brute caprice dooms Sisyphus / To struggle up a never-ending stair.? The second example of allusion that Cullen uses is the story of Sisyphus, who was the king of Corinth and for his efforts in trying to avoid death and Hades, he was condemned eternally to roll a huge boulder uphill. Cullen uses Sisyphus to make a connection to this ?Mortal Coil? we all endure. We all work and go about our daily lives, but towards what end? What is the point of our work and our lives? Is it out of caprice that God has done this to us? Did God doom us to this on a whim? Again, in Cullens view, GodShow MoreRelatedJames Langston Hughes And Countee Cullen934 Words   |  4 Pages James Langston Hughes and Countee Cullen were prominent poets.

Litmus, What Is It and Why Is It Important free essay sample

Litmus, what is it? And why is it important? Litmus was first used around 1300 AD by Arnaldus de Villa Nova, a Spanish alchemist . The word Litmus, comes from the Norse word, meaning ‘to dye, or color’ . Litmus is a common acid-base indicator. Acid-base indicators are indicators used in chemistry as chemical detectors. They provide information about changes in the environment. They are widely used in chemistry due to the fact that they change color reversibly, indirectly indicating the concentration of hydrogen ions present in tested solutions or mixtures. Being one of the most well known acid-base indicators, litmus is a water-soluble mixture of different dyes derived from natural substances, lichens, especially Roccella tinctoria, which is a kind of composite organism consisting of symbiotic association of a fungus with a photosynthetic partner, most commonly green algae . Litmus can be in a dark blue aqueous form, and it can also be absorbed onto filter paper to become the most common and oldest form of pH indicator. We will write a custom essay sample on Litmus, What Is It? and Why Is It Important? or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Neutral litmus paper is purple in color In the presence of acids, blue litmus paper turns pink; In the presence of alkalis, red litmus paper it turns blue. Hence, it is often used for testing for the presence of acids and alkalis. This color change occurs over the pH range of 4. 5 – 8. 3 at 25Â °C. Litmus itself is a weak acid , when it is un-ionized it is red, when it is ionized, it is blue. If litmus is added to a solution where there is a presence of hydroxide ions, the hydroxide ions will react with the hydrogen ions from litmus, the equilibrium position moves to replace the lost hydrogen ions, hence litmus turns blue. Similarly, when it is added into a hydrogen ion containing solution, there will be extra hydrogen ions and so the equilibrium will shift in the other direction, to remove the extra hydrogen ions present, hence litmus turns red. When the concentration of hydrogen ions and unionized limus is the same, a position of equilibrium is reached and the neutral state will be shown by the color purple, a mixture of red and blue. Having many uses in the science field, litmus is certainly an important indicator. It can be used in various fields of science, such as and not limited to, chemistry, biology, and botany. In chemistry, it is most recognized as an indicator used for determining whether substances are basic or acidic. It can also indicate end points during experiments involving titrations. Litmus paper is also very commonly used by chemistry teachers to teach topics related to acids and bases. In biology, litmus paper can be utilized to test specific environmental and biological factors, testing the pH levels. Knowing the pH of the environment is of high importance in this field as most life forms can only survive in a very small range of pH levels. For example, with homo sapiens, humans, the pH levels in their blood have to be very constant, slight changes like blood carbon dioxide levels can easily result in serious damage, coma and may even lead to death. An example of pH testing in this field is the pregnancy test, where the urine acidity of subjects can indicate whether or not they are pregnant. In the field of botany, which is the scientific study of plants , litmus can be used in testing the pH of soil. Plants can only grow in soil of some ranges of pH, if soil is too acidic, they cannot grow or develop properly. If the pH is not right, fertilizers composed of basic components such as calcium carbonate can be used to help foster plant growth. To conclude, litmus is an acid-base indicator with a long history of use in many fields of science and has much importance in those fields. http://chemistry.about.com/b/2009/01/09/what-is-litmus-paper.htm http://www.ehow.com/about_5061005_uses-litmus-paper.html http://en.wikipedia.org/wiki/Litmus http://www.chemguide.co.uk/physical/acidbaseeqia/indicators.html http://www.normalbreathing.com/CO2-blood-pH-respiratory-alkalosis.php http://www.botany.org/bsa/careers/car-what.html
