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. The book can be used to supplement a course in any science, to accompany any course that attempts to give an understanding of the modern work, or-independently of any course-simply to provide a better understanding of science. We hope this book will lead readers to a broader perspective on scientific attitudes and a more realistic view of what science is, who scientists are, and what they do. It will give them an awareness and understanding of the relationship between science and our culture and an appreciation of the roles science may play in our culture. In addition, readers may learn to appreciate the relationship between scientific views and some of the values and philosophies that are pervasive in our culture.
We have tried to present in this book an accurate and up-to-date picture of the scientific community and the people who populate it. That population has in recent years come to comprise more and more women. This increasing role of women in the scientific subculture is not a unique incident but, rather, part of the trend evident in all segments of society as more women enter traditionally male-dominated fields and make significant contributions. In discussing these changes and contribution, however, we are faced with a language that is implicitly sexist, one that uses male nouns or pronouns in referring to unspecified individuals. To offset this built-in bias, we have adopted the policy of using plural nouns and pronouns whenever possible and, when absolutely necessary, alternating he and she. This policy is far from being ideal, but it is at least an acknowledgment of the inadequacy of our language in treating half of the human race equally.
We have also tried to make the book entertaining as well as informative. Our approach is usually informal. We feel, as do many other scientists, that we shouldn't take ourselves too seriously. As the reader may observe, we see science as a delightful pastime rather than as a grim and dreary way to earn a living.

A．cultural groups that are formed by scientists
B．people whose knowledge of science is very limited
C．the scientific community

Section A
What determines the kind of person each of us develops into over a lifetime？ How much are we influenced by our home environment, and how much are we influenced by our genes？ (86) One way that psychologists have tried to answer these questions is by studying twins : identical twins (coming from one fertilized egg, so sharing the same genes) and fraternal twins (coming from different eggs, so sharing 50% of their genes). By comparing these two groups, researchers hope to be able to estimate the influence of genes versus the influence of environment on the development of many human traits, such as personality, talents, interests, and attitudes.
Psychologists from the University of Minnesota have conducted several different studies with over 8,000 pairs of twins and their families. (87) To determine what accounts for differences between twins, they have compared identical twins who were raised together with identical twins who were separated at birth and raised in different families. Their assumption is that any similarity in twins who are raised together can be attributed to both genes and environment, whereas similarities in twins raised apart are clue only to genes, since they had different environments while growing up. Their studies indicate that genes have about a 50% influence on our personalities, while our environment accounts for the other 50%.
(88) Researchers in this study have also tried to test the theory that we each develop a set of criteria for choosing a mate based on our genes and our unique experiences growing up. To do this, researchers compared the spouses of male identical twins who were raised together. They found that the spouses of these identical twins were not much more similar to each other than random pairs of people. They also found that two-thirds of the twins were "indifferent" to their twin's mate or "actively disliked" her. These results indicate that neither our genes nor our upbringing is a good predictor of the spouse we choose. Instead, researchers believe this choice appears to be random, and based more on whom we are near when we are ready to fall in love.
Another question this study has sought to answer is whether twins become more or less similar as they mature. They found that as identical twins age, they become less similar in their physical appearance, but more similar in their abilities, such as mathematical skills. On the other hand, as fraternal twins age they become less similar in these abilities.
Some psychologists are skeptical of twin studies. (89) These critics question some of the assumptions made by twin researchers, such as the assumption that identical twins and fraternal twins have similar environments, or that identical twins raised apart are raised in very different environments. Some believe that, even in the same environment, there can be disparities in the way this environment affects siblings. As a result, it is difficult to determine clearly how much of our personality is genetically inherited and how much is determined by our environment.

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 (小玩意儿); and for the person who views the scientists as some sort of magician. The book can be used to supplement a course in any science, to accompany any course that attempts to give an understanding of the modem world, or independently of any course - simply to provide a better understanding of science. We hope this book will lead readers to a broader perspective on scientific attitudes and a more realistic view of what science is, who scientists are, and what they do. It will give them an awareness and understanding of the relationship between science and our culture and an appreciation of the roles science may play in our culture. In addition, readers may learn to appreciate the relationship between scientific views and some of the values and philosophies that are pervasive (渗透的) in our culture.
