| Science is a dominant theme in our culture.
Since it touches almost every facet of our life, educated people need at least
some acquaintance with its structure and operation. They should also have an
understanding of the subculture in which scientists live and the kinds of people
they are. An understanding of general characteristics of science as well as
specific scientific concepts is easier to attain if one knows something about
the things that excite and frustrate the scientist. This book is written for the intelligent student or lay person whose acquaintance with science is superficial, for the person who has been presented with science as a musty storehouse of dried facts, for the person who sees the chief objective of science as the production of gadgets, and for the person who views the scientists as some sort of magician.
