Many different people in different cultures have made and continue to make contributions to science and technology. (Page 166)

Science and technology have advanced through contributions of many different people, in different cultures, at different times in history. Science and technology have contributed enormously to economic growth and productivity among societies and groups within societies. (Page 169)

Scientists and engineers work in many different settings, including colleges and universities, businesses and industries, specific research institutes, and government agencies. (Page 169)

Women and men of various social and ethnic backgrounds-and with diverse interests, talents, qualities, and motivations—engage in the activities of science, engineering, and related fields such as the health professions. Some scientists work in teams, and some work alone, but all communicate extensively with others. (Page 170)

Scientists formulate and test their explanations of nature using observation, experiments, and theoretical and mathematical models. Although all scientific ideas are tentative and subject to change and improvement in principle, for most major ideas in science, there is much experimental and observational confirmation. Those ideas are not likely to change greatly in the future. Scientists do and have changed their ideas about nature when they encounter new experimental evidence that does not match their existing explanations. (Page 171)

Tracing the history of science can show how difficult it was for scientific innovators to break through the accepted ideas of their time to reach the conclusions that we currently take for granted. (Page 171)



Important contributions to the advancement of science, mathematics, and technology have been made by different kinds of people, in different cultures, at different times. (Page 17)
