Personal Narrative Curiosity Killed The Cat - 881 Words

â€Å"Curiosity killed the cat.† (Anonymous) I believe that was my parents’ perspective on life. In Indonesian custom, the young has to respect the elders, which include parents and teachers. Asking questions or questioning them was considered disrespectful. Holding on to that tradition, my parents taught me to hold on to my curiosity. This upbringing affected every aspect in my life, including my learning style and career options as well. I came from a long line medical field family from my mother side. My mother wanted me not to border the line of curiosity and stay within the cul-de-sac continuing the family tradition by becoming a doctor, a nurse, a midwife, or a pharmacist. During my school years, if anybody asked what I wanted to be when I grew up, of course my answer was to become a doctor. It was instilled in my mind, or so I thought until I met Mr. Tahyana and Aisha who had made a different in the way I view my life. My mother put me on rigorous daily routine of practicing math skills and science since early age . She believed that by mastering these subjects, I would have better chances in the future. I was in a confinement. This over powering method of parenting finally took a toll on me. It seemed that everything I did was not good enough for her. My hatred towards learning started to grow. School became so daunting, that I dreaded coming to school. I couldn’t concentrate, and slowly my grades were getting lower. In the midst of frustration, a friend of mineShow MoreRelated Japanese Alien and Japanese-American Poets In U. S.

Children With Emerald Eyes Essay Research Paper free essay sample

Children With Emerald Eyes Essay, Research Paper Children With Emerald Eyes By Mira Rothenburg My book Children With Emerald Eyes, is about many kids, but focused around three kids placed in an establishment, due to schizophrenic and autistic conditions. These kids? s names are Sara, Chaim, and Danny. The scene of this narrative is in an institute for the insane, schizophrenic, and autistic. Most of these kids are orphans, or kids, that have escaped from their county, and are seeking to happen safety. I feel that their struggle is truly, between themselves. I mean that the chief job is them. They, Danny, Sara, and Chaim are their ain job. They are seeking to run from themselves, but they can? t. In my book there were three different lifting actions, one for each kid. The first lifting action started during Danny? s portion of the book. The lifting action was when he was seeking to interrupt down the emotional walls that his old ways had built. We will write a custom essay sample on Children With Emerald Eyes Essay Research Paper or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Sara? s lifting action started when they described how she was ever desiring everything wrapped, like a present. Following is the lifting action found in Chaim? s narrative is when he got nervous and tried to literally take a bite of himself. The chief characters of this book is Mira, the psychologist and besides the writer of this book. I would name Mira the supporter, because she was the lone 1 who would believe in the fact that these childs could be helped, and she enjoyed making it. At the beginning of the book though, the kids were the adversaries. Throughout the narrative, there was allot of character development, non merely from the kids, but from Mira besides. Through all of the narrative the point of position stayed at a camera 3rd individual. The subject the writer nowadayss, is that of love, fright, friendly relationship, treachery, turning up, and a hunt for one? s ego. I feel that the most of import message of this book is that even though one can experience betrayed by person, there can still be friendship between them. My sentiment of this book is one a miss normally have towards person or something, but I think that this book was really traveling. I feel that it touched base on everything a book should. There wasn? t really many things I didn? Ts like about this book except the point that it rather difficult to follow. As a affair of fact it has, it has changed the ways I look at the manner mentally challenged kids act.

Particle in a Box Experiment Essay Example

Particle in a Box Experiment Essay The visible absorption bands or conjugated dye arise from electron transitions involving the electrons in the conjugated and they are free to move along the chain and are not attached to any atom. An example of such a dye is 3,3-diethyl-thiacyanine iodide. The cation has two resonance forms causing each of the bonds in the conjugated chain to have an order of 1. 5 and have a length similar to the C? C bond length in benzene. We will assume that the potential energy is constant along the chain and sharply rises to infinity at the ends.Therefore, we can replace the electron system by free electrons moving in a one dimensional box of length . Objective: The purpose of this experiment is to obtain the visible spectra of several cyanine dyes and then interpret them to a simple model of the electronic structure of the ? system: the Particle in a Box. Theoretical Model â€Å"Particle in a Box† In the Particle in a Box model, all potential energy interactions are assumed to be zero (c onstant) along the chain except at ends of the chain where the potential energy abruptly goes to +?. If a particle moving freely along the length of the box the energy an be calculated as : E = n2h28mL2 + V n = 1, 2, 3 †¦ (1) where n is an integer positive quantum number, h is Planck’s constant, m is the mass of the particle and L is the length of the box. If we assume that the most intense band in the experimentally observed spectrum can be interpreted as absorption of electromagnetic radiation by an electron as it is promoted from the HOMO to the LUMO, we can derive the following expression for the energy absorption ? E. E =h2 [2ni+ 1]/ (8mL? ) (2) he absorption wavelength for the HOMO _ LUMO transition is given by: ? = 8mcL? /h (2ni + 1) ni = p p = #e/2 (3) Therefore, the Particle in a Box model predicts that the wavelength of the absorption maximum is a function of chain length (L) and number of p-electrons (N). The adjustable parameter Lmax can be calculated as: ? = 8mc/h(2p+1)[(2p-1)Lb + Lext]2 (4) ?max h/8mc=[2p-1Lb + Lext ]2/ (2p +1) (5) Procedure: In this experiment, we used the following dyes. Dye #1: 3,3-diethyl-thiacyanine iodide (yellow) Dye #2: 3,3-diethylthiacarbocyanine iodide (Pink)Dye #3: 3,3-diethylthiadicarbocyanine iodide (Blue) Dye #4: 3,3-diethylthiatricarbocyanine iodide (Olive) We placed 0. 3 ml of dye solution in the 1- cm cuvette and added 3. 00 ml of water and mixed well. Using the nano drop spectrometer, first cuvette with water was used as a blank and later second Cuvette with dye solution was inserted and measured the absorbance of the sample. Once our absorbance of the highest peak was less than 0. 5 and the absorption spectrum of each dye was between 400-800 we collected the data. Notes On Wavelength:If only changes in electronic energy accompany absorption of light, a very sharp maximum in absorption should be observed at the characteristic wavelength. Although sharp lines are observed for isolated atoms, broad ab sorption bands are observed for substances in liquid phases (due to the accompanying vibrational and rotational transitions). In the experiment, we shall assume that the wavelength ? max, the wavelength at which the dyes absorb most strongly, is the wavelength to use in the equation (5). Data/Result: A UV-Vis absorbance spectrum (Fig 1) was obtained and used to calculate experimental ? ax values for each of the studied cyanine dyes.

This can be due to the electronic transitions from state to state which occur within a time interval much shorter than that of a molecular vibration and also experimental error was responsible for the lack of resolution.The collected electrically spectra were useful in comparison of experimentally and theoretically predicted ? max values and it shows that the experimentally determined values are close to the predicted value. Extracting Lext from equation (5) for each dye doesn’t follow the observed trend in the absorption maxima. For 3,3-Diethylthiacyanine Iodide and 3,3-Diethylthiacarbocyanine Iodide dyes as ni increases Lext and ? max increases and in 3,3-Diethylthiadicarbocyanine Iodide and 3,3-Diethylthiatricarbocyanine Iodide, Lext decreases as ni increases. The experimentally calculated Lext for compounds 1-4 was determined to be 6. 2E-5 m which doesn’t seem sensible. Large differences existed difference between the calculated effective box length compare to lb. From the experimental evidence and analysis, we don’t except the particle in a box model to be an appropriate one to describe the spectra of cyanine dyes. Since the errors in the ? max are not normally distributed experimental errors.Work Citedhttp://homepages. gac. edu/~anienow/CHE-372/Labs/Example. pdf http://homepages. gac. edu/~anienow/CHE-372a/Labs/Conjugated%20Dyesa. pdf
