Technology influences the quality of life and the ways people act and interact. Science and technology have advanced through contributions of many different people, in different cultures, at different times in history. Scientists and engineers work in many different settings, including colleges and universities, businesses and industries, research institutes, and government agencies. Science cannot answer all questions and technology cannot solve all human problems or meet all human needs. Science requires different abilities, depending on such factors as the field of study and type of inquiry.
Scientists formulate and test their explanations of nature using observation and experiments.
It is normal for scientists to differ with one another about the interpretation of the evidence. It is part of scientific inquiry to evaluate the results of scientific investigations, experiments, observations, and the explanations proposed by other scientists. History of science Many individuals have contributed to the traditions of science. In historical perspective, science has been practiced by different individuals in different cultures. 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.
