Theory, Invention, and Practice [President's Message]

In this column, I would like to write about my own experience on theory, invention, and practice, including how I became more interested in applications and how that realization materialized. I would like to share some thoughts on what I did right and perhaps more on what I should have done but did not. I hope my two cents can help some readers to become more interested in inventions and get an idea of what we can do and how we can proceed from a tiny bit of a small idea.
