What exactly is life? I do not have an answer. But now, the twenty second years of my life has passed, I have seen and met probably more than one thousand different people. Who is the most successful one in my point of view? Who do I want to be the most? What exactly do I want to achieve at the end of my life? It seems to me that I have find an answer this year, although I do not believe I will not be able to be him, he is my target.

Every person has his own philosophy-Wisdom in Greek. Maybe defined as religion, but I defined it as science. This is the reason I do Physics, in my point of view, it is only Physics or Mathematic can describe nature elementarily. One of the best example is, if you keep cutting a piece of bread half and half, what do you get? Will we be able to do that for infinite times? Or will we reach a point we can’t cut furthermore? Seems to me only Physics can tell me the answer, and that is the reason why I have been taking this course for four years with an increasing motivation
The person who I personally considered as the most successfully, I spoke with him today, haha… He is the lecturer of my forth year course, Quantum Field Theory(QFT). Before the exam of QFT started, he announced the three typos, I only managed to hear the two and missed one, I was thinking of leaving it, however, after it started and I was stuck in one of the questions. So I waved him down and asked him ‘What was the second typo you mentioned?’ Hehe… He was very helpful, thank you, however, the typo did not affect me as it’s in another questions which I did not attempt. What is the reason I think he is great? It’s his knowledge I would like to achieve. Having an opportunity to think about how does the nature work, seem to me it the whole purpose of human being or even for all other organism, rather than reproduction.
