With 15 inventions in my name, I started to think in terms of commonality in them. Then it occurred to me that perhaps DUALITY is at play. Three of them I examined and found evidence of it. Others I have left for readers to explore and determine what if any duality exists in them. DUALITY: THE VERY FOUNDATION OF OUR UNIVERSE DUALITY controls everything, I mean EVERYTHING. It is a law of nature that exists everywhere there is a physical world in the universe. If this is the FACT, then why should we ignore it. Knowing that even a stopped analog watch shows correct time twice a day tells us how pervasive DUALITY is. DRIVE INNOVATION: BY APPLYING THE DUALITY PRINCIPLE NO innovation is easy. Some can happen with brute force or following time-tested methodologies. But wouldn't it be great if there in an ANOTHER WAY or method to THIS madness. A case study FIT TO PUBLISH: how THE USE OF duality innovation principle can INCREASE SALES for the COMPANY we know as "CROCS."
