When we return wild animals to nature, we merely return them to what is already theirs. For man cannot give wild animals freedom, they can only take it away.

What is a scientist after all? It is a curious man looking through a keyhole, the keyhole of nature, trying to know what's going on.

I experimented with all possible maneuvers-loops, somersaults and barrel rolls. I stood upside down on one finger and burst out laughing, a shrill, distorted laugh. Nothing I did altered the automatic rhythm of the air. Delivered from gravity and buoyancy, I flew around in space.

I believe that national sovereignties will shrink in the face of universal interdependence.

We must go and see for ourselves.

I wake up saying, I'm still alive; a miracle. And so I keep on pushing.

However fragmented the world, however intense the national rivalries, it is an inexorable fact that we become more interdependent every day.
