Here's my answer the MIT's question :
Although you may not yet know what you want to major in, which department or program at MIT appeals to you and why? (*) (100 words or fewer)
Math is my passion: I absolutely love spending hours trying to figure out a way to solve a really tough problem. And, the pleasure and fulfillment I sense after finding that solution is such that I know it's what I want to do later, what I want to study. Arithmetic and algorithms are my favorite; I am fascinated by cryptography, codes, and computer programming's world, which tempt me a lot since I've started reading Dan Brown. Plus, I've always been curious about computers' impressive coding and programming abilities. Thus, I want to be, someday, an engineer that would create a really powerful code-breaking algorithm, or an algorithm that would analyze financial markets. My craving for computer science and math makes, therefore, MIT's Electrical Engineering and Computer science department the most appealing to me.
