own fields of work as Simply and to as many as possible-and if non-
scientists, for their part, accepted the responsibility of listening.  To gain a satisfactory appreciation of the developments in a field of science, it is not essential to have a total understanding of the science.  After all, no one feels that he must be capable of writing a great work of literature in order to appreciate Shakespeare.  To listen to a Beethoven symphony with pleasure does not require the listener to be capable of composing an equivalent symphony of his own.  By the same token, one can ap-preciate and take pleasure in tb@acbievements of science even though he does not himself have a bent for creative work in science.
But what, you may ask, would be accomplished?  The first a nswer is that no one can really feel at home in the modern world and judge the nature of its problems-and the possible solutions to those problems-unless be has some intelligent notion of what science is up to.  But beyond this, initiation into the magnificent world of science brings great esthetic satisfaction, inspiration to youth, fulfillment of the desire to know, and a deeper appreciation of the wonderful potentialities and achievements of the human mind.
It is with this in mind that I have undertaken to write this book.
