Long journey into tunneling.
I am, of course, deeply aware of important contributions made by many colleagues and my friends throughout this long journey. The subject of the second section was carried out when I was in Japan and all the rest (35) has been performed in the United States of America. Since my journey into tunneling is still continuing, I do not come to any conclusions in this talk. However, I would like to point out that many high barriers exist in this world: barriers between nations, races, and creeds. Unfortunately, some barriers are thick and strong. But I hope, with determination, we will find a way to tunnel through these barriers easily and freely, to bring the world together so that everyone can share in the legacy of Alfred Nobel.
