I believe our future depends powerfully on how well we understand this cosmos in which we float, like a mote of dust in the morning sky.

Ours is the first generation that has grown up with science-fiction ideas.

Time spent with children is time well spent. Their little minds are not constrained by 'reality' or focused upon goals. Anything and everything is possible. Imagination will often carry us to worlds that never were. But without it we go nowhere.

Accommodation to change, the thoughtful pursuit of alternative futures are keys to the survival of civilization and perhaps of the human species.

For a long time the human instinct to understand was thwarted by facile religious explanations.

Books permit us to voyage through time, to tap the wisdom of our ancestors.

I am often amazed at how much more capability and enthusiasm for science there is among elementary school youngsters than among college students.
