How Long Should Your Harvard Application Essay Be

Harvard Business School has really gone out of its way to present itself in opposition to the  stodgy, elitist image it tends to hold in the MBA world. Through the use of its blog and a more simplified application and essay format, HBS has taken a much more casual approach to letting candidates tell their story during this years application season. This approach has primarily manifested itself through the school’s choice to only offer one essay prompt in their application. As opposed to other MBA programs that require applicants to write  two, three, and sometimes  even four essays, Harvard’s sole essay requirement puts a lot of pressure on applicants to make the most of the limited word count they are given in this one chance to impress the Admissions Committee. But wait, what word count? The last few years, Harvard has also done away with adding a word count to their essays,  putting the decision of length  for the school’s only essay in the hands of the applicant. I know this is HBS, and like most applicants you will probably  want to share as much of your story in this essay as possible to convince the school of your merits, but this essay is more about how you can effectively communicate a response to an open-ended question in a concise and compelling fashion than it is about cramming every detail of your professional and personal life into one essay. The best way to do this is to answer the question asked and only the question asked. Harvard is looking to get a response to the question they have asked for a reason   if they wanted additional information from you, they would have asked or will ask in other stages of the application process (through the application form, interview, etc.). As such, youll want to keep your response to this essay short. Avoid responses that stray above 1,000 words and settle into the 500-750 word range, instead. An essay that is 1,000 or more words is almost a whopping 15-minutes when read aloud! Keep in mind the school’s guidance: â€Å"don’t overthink, overcraft, and overwrite.† This is literally the approach you should take here. HBS receives almost 9,000 applications every year   that is a lot of reading, so the further you stray over 1,000 words,  the more of a disadvantage you put yourself at. If you are struggling keeping your essay concise, make sure you are avoiding answering traditional MBA essay topics that are not actually being asked in the prompt. Often applicants get nervous if they do not have the opportunity to formally communicate common business school information like â€Å"Why HBS? or â€Å"Why MBA?†. Avoid this temptation and respond to the prompt in a concise, authentic, and compelling fashion to give yourself the best chance of success in crafting your Harvard application essay.

The Things They Carried Vietnam Essay - 1571 Words

How Society Influences Man: Tim O Brien in Vietnam Tim O Brien s novel The Things They Carried is meant to display the effects of Vietnam on both American soldiers as well as the boys they once were. Vietnam is a society where human decency is left behind, and death is embraced as either a joke or an escape--where the horrors of reality are turned comical and exaggerated in order to keep going. Tim O Brien shows how Vietnam turns him from a boy unknowing of death, to a young man unwilling to face it, to a soldier laughing in the face of it, to a veteran unwilling to leave it behind, and finally, to an author left to make sense of it all. Before describing the effects of Vietnam, first it is necessary to know how Tim O Brien was†¦show more content†¦By this point, he is a different person than he was as a child, a college graduate with a distaste for the Vietnam war like many other American citizens of the time. He believes himself to be too smart, too compassionate, too everything for the war (O Brien 26). By being forced to war by a draft board, he rages against having no options and the unfairness of it all---he revels in his righteousness, his feeling of being wronged, and uses this to help convince himself that he has every right to run from Vietnam. O Brien convinces himself he has every right to run from death, yet still managed to be divided when it came to actually getting up to run. Thus, when he abandons his little town to flee to Canada and escape the war, his constant juggle between doing what was expected of him and doing what would keep him alive is the conflict between the young boy clinging t o Linda alive and healthy and the soldier he will soon have to become. In the end, his fear of facing the disappoint of his family and peers is too great, and he returns home to face the war. While this decision is what gets him to Vietnam, however, it is not the decision that alters him forever. No, it is Vietnam that sheds away both the little boy O Brien once was and the righteous college graduate who feared his town s judgement. Vietnam, in a way, is much like a person, and how it adapts to affect individuals is beneficial to understanding how it changed O BrienShow MoreRelatedComparison of the Vietnam War and in The Things They Carried Essay1792 Words   |  8 PagesIn the twentieth century many young adults and many other men were chosen/ drafted to enter the war.

Descriptive Essay About Losing A Pet - 982 Words

Among the saddest truths about this lifetime is this: A dog’s life is significantly shorter than a human’s life. I said goodbye to my beloved Miniature Schnauzer, Samson, on March 26th, 2017. He was ten years old. It is an opinion to say that losing a pet is like losing a member of the family. The fact is, though, it is an understatement. Dogs are unique in their own ways. As it is said, â€Å"Grief is the price you pay for love.† And I paid a heavy priced that day. It is unbelievable how we take things for granted. Plans are made for each day, and we do not think twice about those plans. Unfortunately, they can change in the blink of an eye. I never personally thought much about it, until I was faced with the shock and tragedy of the death†¦show more content†¦Pam Brown once said, â€Å"If there is a heaven, it is certain our animals are to be there. Their lives become so interwoven with our own than an archangel to detangle them (Brown,n.d.).† He is now buried in our backyard with his own stone with the words, â€Å"You may have left my life, but you will never leave my heart† engraved. We received many sympathy cards, but it did not make the situation any better. However, it was nice to know my friends and family cared. It was the saddest time in my life. Not a day goes by that I do not think about him. It is very tough to not break down when I think or talk about him. He was a special boy. For the longest time, there was a void feeling in my house. A hole was left in my family’s hearts. I knew Samson would have wanted me to give his doggie bed and squeak toys to another deserving dog. He had a wet nose and a huge heart. Once, in the first week following his passing, I came through my front door and looked at the area where he would usually be sitting or lying. I called for him with the foolish notation that he would appear and come running to me. But of course, he did not. Then, I walked past his empty foo d bowls and tears started running down my face. It was a shattering reminder that he was gone and never coming back. Grief was exhausting and painful to say the least. The day after Samson died, I could not drag myself out of bed.

Recrystallisation helps to eliminate impurities; the precipitation process eradicates soluble impurities as aspirin has a higher precipitation temperature so converts to a solid while other impure components are left as soluble in the solution. The yield is calculated to look at how well the reaction has been completed. This reaction is simplified to: C7H6O3 + C4H6O3 C9H8O4 + C2H4O2 To work out the yield; 0. 917g of 2-hydroxybenzoic acid (0. 917/138) * 180 138 (the molar mass of 2-hydroxybenzoic acid) 180 (the molar mass of aspirin) Theoretical yield: 1. 196g 3 d. p.

An impure compound will exhibit a lower melting point than this, which is what was observed in both the willow bark product and the crude aspirin. Pure aspirin has a narrow temperature range during which it changes from a solid to a liquid; this range is less than 2 °C. The sharpness of the melting point is useful to measure purity using pure aspirin as a comparison. As both types of aspirin melted over a temperature range of 5 °C it’s indicative that both substances have many impurities. The range of melting points for the crude aspirin and product of willow bark in comparison to the pure aspirin is obvious and can show the level and amount of impurity in both compounds. Chromatography Different constituents of each mixture travel at different speeds along the paper causing the components to separate. Above is a picture of the chromatography, comparing phenol (P), 2-hydroxybenzoic acid (2), pure aspirin (A), crude aspirin (I) and product from willow bark (W). Only two of the spots have been circled here, more were seen after this picture was taken but an image of the final separation was not photographed only observations were made (see table).

The documented Rf for pure aspirin is 0. 56; however this experiment shows pure aspirin to be 0. 95, therefore for the purpose of comparison the documented value shall be used. This could be due to contamination, incorrect processes in the procedure, the amount of solution used or the temperature of the solution, although some of these fa ctors are difficult to keep constant in the environment. The Phenol compound was used as a comparison. The result shows phenol is lighter than pure aspirin as it doesn’t contain as many atoms in its structure, with a molecular mass of 94. 11 g/mol. See Fig 1. 2-hydroxybenzoic acid, which is the main metabolite of aspirin, shows it is also molecularly lighter (in that it is moved further up the paper when soluble) than crude aspirin or pure aspirin. We would expect to see this because crude aspirin consists of the mass of 2-hydroxybenzoic acid and other compounds giving a total mass of 138. 12 (g mol-1). The pure aspirin shows only one spot on the paper, this is because it consists of only one compound, that being 2-acetoxybenzoic acid (aspirin). Pure aspirin has a molecular mass of 180. 157 (g/mol). The synthesised crude aspirin also shows only one spot but this is very far away from the pure aspirin Rf, although it could consist of multiple components close in mass so they merge into one spot. This clearly qualitatively shows the level of impurity as it is much heavier showing it contains other compounds weighing it down, which it should not have if synthesised meticulously. The willow bark product produced 3 spots on the paper which indicates it has multiple constituents all heavier than pure aspirin therefore is impure. This was expected because of the source, although the TLC (thin layer chromatography) paper could have been accidently splashed with an organic compound during the experimentation process and thus distorting the results by showing extra spots, this is unlikely as it’s expected that the willow bark product will be heavily impure. The paper also shows an elongated spot which is due to the solution being too concentrated. Fig 1.

An above observation was made when sodium carbonate reacted with 2-hydroxybenzoic acid which was expected due to CO2 being released when an acid and a carbonate combine, below shows the reaction that took place. C7H6O3 + Na2CO3 NaC7H5O3 + H2O + CO2 No reactions were observed for the crude or pure aspirin which revealed the 2-hydroxybenzoic acid had formed a new product during synthesis which has no reaction with sodium carbonate. This was the outcome required and was achieved based on this test. The product derived from willow bark also showed no reaction as it had no component within it that reacted with sodium carbonate, no acid group within this natural product. 2. Reaction with Fe3+ CompoundColour with Fe3+ PhenolIntensely Purple 2-hydroxybenzoic acidPurple and frothy Crude AspirinPale purple, almost translucent Pure AspirinLight brown Product from Willow BarkBlack A solution presenting purple when mixed with an iron group shows the presence of a Phenol group. All mixtures, apart from the pure aspirin, exhibited this although all varied in colour intensity. Aspirin doesn’t have a Phenol group as can be seen from the lack of purple in the solution so this can be used as a control along with the phenol solution itself. From this test it can be seen, to what degree each compound has a phenol impurity. The solution containing the crude aspirin only changed to a slight translucent purple indicating a low level of 2-hydroxybenzoic acid (as can be seen this compound reacts strongly to the addition of Fe) and so the crude aspirin has impurities but only to a certain degree. The pure aspirin shows how a  compound with less impurities shouldn’t contain phenol and how this reacts in the solution and what colour should appear, colours away from this contain impurities. The willow bark product displayed an intense black colour, possibly so purple it looked black, so far away from the pure aspirin colour that contaminations are certain. Evaluation All procedures and processes of each stage of synthesis had variables that could result in an impure product. Although the recrystallisation stage, to remove impurities, was performed by an experienced laboratory staff member errors could still have occurred and these must be considered. Before the crude aspirin was recrystallised it may have contained various impurities that were not all eradicated by the precipitation process, these could include: contaminations in the air and C2H4O2 (a product of the original reaction), along with contaminations in the distilled water used, although this is better than using tap water. A high or even moderate yield was not achieved. This could be due to many factors; the experience of the chemists producing the aspirin having a poor laboratory technique, thus procedures were not carried out effectively and without error. Percentages of the substances could have been lost or misplaced during stages of the procedure. Other variables that could lead to the yield being less than 100% are: transfer of the product between containers, an incomplete reaction could have occurred, and is likely to have, where each compound does not fully react when it should due to factors beyond control, this will lower the products final mass. Recrystallisation also loses product and therefore yield as some product may still be left in the solution or on the filter paper. The aspirin may not have dried properly; making the mass higher therefore the purity would be lower. This factor could have distorted all results consequently when comparing, all would have the same distortion. The melting points may have inaccuracies as the temperature at which the willow bark melted was debated by the group. Lack of concentration and difficulty in determining when it had melted may have led to the product melting fully before it was observed and this would lead to a distortion of the results. It would be expected that the willow bark would melt at a higher temperature that the crude aspirin as it is known to have more impurities. Conclusion The overall objectives were to synthesise aspirin from 2-hydroxybenzoic acid and willow bark, and qualitatively determine the purity of each product, this was achieved as aspirin was produced from both the willow bark and the substances. The results from all tests do display that there were impurities, although they did not all show a consistent level of impurity. There was a noted difference, but not greatly so, in appearance between the crude and pure aspirin when tested with the Fe3+ solution. In contrast the TLC test exhibited a drastic comparable difference between the crude and pure aspirin. Possibly this was because the TLC did not use a subjective scale like the other tests, the quantitative measurability of the results allowed the outcome to be easily compared to the other products and against the pure aspirin. All tests showed a qualitative visual level of impurity in the results. Although this level varied and cannot be compared due to the difference in format of the results for each test, it can be seen, in general, that the crude aspirin contained more impurities than the pure aspirin and the willow bark product was the most impure of them all. This was expected. Although a ‘pure’ aspirin was synthesised from the crude, this is still an aspirin substance synthesised in a college laboratory by college students who are not skilled in laboratory practice and could have contaminated the experiment at various stages and not been astute enough to record and monitor reactions well. This could lead to the ‘pure’ aspirin only being a certain level of pure itself therefore any comparisons made against it are relative to that aspirin not the aspirin on the market/in stores. This can be seen in the chromatography test where documented aspirin has a retardation factor of 0. 56 but the synthesised pure aspirin is much lighter meaning it may not contain all the compounds found in correctly synthesised aspirin. To conclude if all variables and experimenter error was controlled a purer product would have been made and a higher yield would have been produced. Not all variables can be accounted for and therefore a 100% yield can never be achieved, even in a manufacturer setting.
