I have been concerned with a single problem on my research project, for about a month. Since the end of the last year, this problem stucks in my head for long long time. I have tried various ideas and calculations, but all of them failed so far. Last week, I changed the approach again, but the success is still far away. If you are a theoretical physicist, you know that I am now very much enjoying the moment of struggling. This is the most interesting and joyful part of research. I experience battle of various notions and ideas of D-brane physics, sometimes they conflic each other, sometimes they coorporate with each other to form a new interesting notion of physics. This is the moment for which I live.
I cannot tell the problem in detail here, since it is an on-going research subject. It is on a new description of nuclei, coming from D-branes and superstring theory. If this is successful, this would give a totally new description of nuclei, but… who knows if it will work out or not.
Tomorrow, again, I will experience the excitement, and the life of a scientist is like this every day.
