This section covers my knowledge and opinions on various issues of my interest. It is obviously subjective; may or may not be conventional. Always guard with your own judgement - well, I don't even know when I will be able to finish any of these writings. I know what I want to say. But I need time to read and learn so that I could present clearly my original ideas (if any) and appropriate references.
So, this page will be an empty nest for a long time. It is just a space taker.
