my first post

This is my first blog. I have no idea whether it will be filled with my writings. I might be lazy to write yet sometimes my mind just pop up with some new insights and new findings. It would be wasteful not to write it down. Furthermore, i often come across some interesting articles. Well, I think I will just copy and paste the articles on this site hopefully not violating any copyright. Just in case, the site went offline and the precious articles disappear.
