What inspires my research?

 

When I think about the nature of research (philosophically :-)), it reminds me of the amusement of a child when he sees the world around him for the first time, and then his endeavor to make meaning out of the seemingly meaningless things. Research, for me begins by exactly the same kind of amusement regarding a phenomenon, followed by simple questions in the pursuit to understand things better. Once this process is done, one is generally in a position to think beyond and at times discover things unheard of in the past. This research process brings to me many kinds of joys: joy of learning new things, joy of understanding things better and the joy of accomplishment. Moreover, I feel that research is vital for shaping the world of tomorrow. It is these ideas that drive my research.
