The other day I went to the Japanese Masuli and I won a raccoon and it became the company of Logan and I when we are playing piano. We decided to call it "the super pianist" because he is black and white (resemble the coloring of the piano keys) and seems to be strict if you look into his eyes.
Today I received an email about publishing online portfolio on the architecture website. There is a request for sending the thumb nail. The thinking process of the thumb nail is influenced to a great extent by Set Theory.
In the first semester of my graduate study at Carnegie Mellon University, I have met Computer Science and fall in love with it immediately. I formed a possibly bad habit of writing my wishes on the pair of jeans I am wearing and keep watching them days after days and anchor them into my head and hope that some day I can realize some of them. I remembered on that very pair of jeans that accompanied me through my sleepless application process and my first semester in the United States, Set Theory was listed as one of them. I finally have a chance to get a little close to it this semester. The instructor of Set Theory is Prof. Clinton Conley. I am very glad that I can take Set Theory under his instruction and I enjoyed the topics a great deal. I might have become a somewhat "troublesome" student by bothering him with a lot of questions, both as a result of curiosity about the subject and an insufficient mathematical training so that things obvious to others might not be obvious to me. These days I sometimes will think back about the days when I was taking Concepts with Prof. Tim Flaherty and also enjoyed that very much. During that lecture, Prof. Flaherty suggested that I might be interested in courses like Foundations. He might be glad to know I am touching half of that by set theory. I have detoured too far away from what I was originally going to discuss, which for me is always an issue... Recently my journey of Set Theory is going through the section of metric and topological space. We are working with "open" sets pretty often and the "open" sets are, by convention, denoted by different types of "U"s, fancy "U" (the \mathcal one), normal U, and since "the union of open sets are also open" is used frequently, there is also a concern of differ the set notions of U and the union symbol. So, as a result, I found the letter "U" an interesting letter and I decided I will put "U" in my thumbnail. Why "U" is related to me? # It is considered "open". In a set theoretic sense, it means for all x \in U, there exists an open ball with positive radius that is a subset of U. Intuitively it means there is no boundaries. That is like me in some sense, because I have no boundaries and I am open to new knowledge and field. # It is the universe (especially in Concepts, we always use U as a special name for the universe set.) Sometimes I am just intrigued by the abstract and non-reachable things, so the "universe" is a pretty good canonical representative for such things. # It looked similar to the union symbol. As a purely personal preference, union appeals to me more than intersection, because it is in ZFC ahahaha ~ # It is the initial for "useless", which describes me pretty well, as I have a tendency of being attracted by things that do not have a direct application (such as piano, math and painting etc.) |
