Personal statement Peoplearound me always ask me why I apply to a foreign university after working fortwo years, for this seems to be a crooked road. I will answer them that this ismy dream. All I have done, four years of undergraduate study majoring inphysics and two years of working, is to prepare for chasing my dream – studyingabroad and becoming an astronomy scientist in the future. My interest inastronomy can date back to my childhood, when I was fascinated by the starrysky. Since then I started to dream about becoming a scientist, so I can unveilthe mystery of the universe by myself. Myundergraduate experiences in Jilin University equipped me with a solid foundationin physics and mathematics, as can be seen from the grades of my physics andmathematics courses. I was not confined by the content printed on the textbooksor taught by teachers and often asked why it was so. For instance, in the ModernPhysics Experiments class, we measured the crystal property using XRD method.In the process we needed to grind the specimen to powder. So I wondered thatsince the lattice of each crystal grain would arrange randomly, how thesegrains could cause diffraction in special direction. I turned to my teacher forhelp and he explained the principles behind this phenomenon. In September 2010,I participated in the Contemporary Undergraduate Mathematical Contest inModeling (CUMCM) with other two teammates from the College of Software. I wasin charge of allocating assignments for each member and accomplishing thecomputational problems by using MATLAB. As a result, we won the first prize inJilin division and the second prize in the national level (820 out of 12,272teams). Inaddition, I seized every opportunity to enrich my knowledge about astronomy. Inthe first year of my undergraduate, I joined the astrophysics group in ourcollege, which was composed of students interested in astronomy. We held one activityevery week, ranging from lectures to outdoor observations. In order to bequalified to talk with other knowledgeable teammates, I learned some coursesabout astronomy by myself, such as Physics-Astronomy Frontier and Foundation ofTheoretical Astronomy. These articles about astronomy and cosmology onScientific American also obsessed me. I was particularly interested in the starformation and evolution theory. What happened in the giant molecular clouds?How did these dense and ordered structures emerge from these superficiallychaotic areas? My knowledge was far limited to deal with such a complex systemthat included enormous unknown interactions. It confirmed my determination topursue a high degree in astronomy. I also tookan active part in real research work. During the summer holiday of my sophomoreyear, I worked as a research assistant in a laboratory in Jilin University Atomand Molecular Institute of Physics. To understand the methods frequently usedin our research, I studied the density functional theory (DFT) by myself. Icalculated potential energies of molecules in different states with scriptinglanguage code. It enabled me to have a better understanding about the theoriesI learned in Atomic Physics course. In senior year, I completed my thesis“ThePreparation of Nano ZnO and the Study of Its Structure and Optical Properties”.I finished the research all by myself, including designing the experimentprocedure, conducting the experiment and studying the property of the specimenby using SEM, XRD and photoluminescence detection. The beautiful images of NanoZnO hexagonal prisms under SEM brought me huge joyfulness. All seemedto go smoothly and I prepared to further my study in astronomy after Igraduated. However, my family encountered financial crisis and some otherdifficulties in my junior year, which made me hesitated to study for a higherdegree. On one hand, I did not want to ask for money from my parents. Duringthe undergraduate period, I paid for my tuition by student loan, which had tobe returned after I graduated. On the other hand, I wanted to do something to supportmy family. My father was an ordinary farmer and sometimes he would do somephysical work in the factories when there was little farm work. As a grown-upwho had received my parents’ nurture for so many years, I should do something. Soafter pondering seriously I decided to adjust my plan i.e. I would tentatively putaside my study after I graduated and go to find a job. Althoughmy job had no relation with physics, it did benefit me in many aspects. Mysecond job position was a software engineer in test, offering me more opportunityto learn computer knowledge. I became familiar with the structure of Linux OSand shell script since most of our products were based on Linux OS. Because ofmy excellent performance, I was appointed to be in charge of the test work in atotally new program- the smartSTB (set top box) based on Android operating system, which was intended forabout 2,000 users. I designed the test requirements and procedures, and thencarried out the test. After six months’ hard work, including many overtimenights, our team successfully accomplished the program. Therepetition and busyness of my work did not rub off my dream. Instead, it loomedlarger in my heart. I paid off my loan, helped my family to come through the difficultywith my wage and became financially independent. Now, the time is ripe for me toresume my study. I pick up what I learned in the university and attempt toapply to an American university. I believe a gradate study is the mostimportant step to realize my dream, especially studying in the place that maintainsthe highest academic level in the world. The graduateprogram of the Astronomy Department at Boston University covers variousresearch areas. This will render me a good opportunity to have access to manycutting edge researches before I choose a specific field. Moreover, thelocation of the university and diverse student activities intensely attract me.I really hope to be one member of this energetic group. How manyyears must a man wait, before he can chase his dream? The answer is two yearsfor me. This path seems to be crooked in others’ eyes, but for me it’s thedecent one. The obstacles I have to overcome in the path make my dream morevaluable. I will maintain this firm belief in my future study and academiccareer. Thank you for your kind consideration of my application for graduateadmission.
