Theory and Applications

Sometimes I couldn't help to wonder: Am I a theorist or a practitionist? Or should we distinct these two as two different objects,or even think these two are on the each side of a polar. And I sense that there is a trend that one does not respect the other. I realize at least I have this kind of prone. And I also notice that most theorists pay no attention to the application, and the practitionists do the same things. I think for any subjects, there are three kinds of people, one is pure theorist, one is trying to put the theory he understands to the practice, one focus only on practice, he assume the existence of a theory foundation for his work, all he need to do is improved the practical impact of it. If this kind of situation is true, I feel that my favor is somewhere between the first two, or I want to be both the first two kind of people at the same time. yes, I want to invent my own theory, and see how it work out in practice. And the sadness is some theorist cannot see the flourish of his theory in their lifetime. But, I want to be an optimist, and with the hope and passion, to delve into the pure theory,figure out the essential relations of the objects.
