I wish every graduate student or young inventor would have the pleasure of seeing his/her ideas spread so far and influence the work of so many people. I also hope that the story of the bold rejection of our novel idea and its eventual international success, is an inspiration for anyone whose new ideas are rejected by some respected authorities.
