If you could study a subject that you have never had the opportunity to study, what would you choose? Explain your choice, using specific reasons and details. In today's world inundated with many kinds of subjects and knowledge, although there are a lot of subjects which is very arresting me, nevertheless, the most interesting subject for I is heat transfer. The issue of the diversity of application and my interest illustrates why it is so. To begin with, as long as it exist the temperature difference between two bodies or two elements, there are some heat exchanges or reactions between them, so the applications and problems relative to heat transfer are very vast from the bigger applications: ocean system and atmosphere moving to the smaller applications: nano-technology and molecular reaction. Because I see that heat transfer is the cornerstone of other subjects or fields, if I would like to learn other difficult discipline, I have to understand the basic concept of the discipline including heat transfer. On the other hand, I regard heat transfer as math and calculus, if you could learn those basic subjects well, I could acquire all kinds of knowledge and information as much as I desire. That is why I think the subject which is crucial and pragmatic worthy of studying. Additionally, I very interest in increasing my computer's ability recently; however, I discover that the computer's ability is limited by the central process unit, CPU, and other chip module. Moreover, the CPU and chip module is not only limited by their intrinsic ability but also constrained by their operation environment. The most important factor of operation environment is temperature; your computer would perform well as long as you could maintain the temperature of your computer in a reasonable range. In addition, your also could increase the performance if you could reduce the temperature at the same time. However, how to control or reduce the temperature is not a easy job relative to heat transfer, because if I could remove the heat from my computer's case, the temperature is easily controlled. From the reason I mentioned above, I think that if I could reform some elements in my computer in order to improve the heat removing efficiency, I would spent less money to getting a high performance computer. The knowledge of heat transfer is essential for me to reform my computer. In conclusion, although heat transfer is not the most popular subject, we still could find many trails of heat transfer in our life, if I could acquire the knowledge of heat transfer; I think that I could understand lots of base concept of products. Moreover, I could solve many problems relative to heat transfer and make something better. --
