The word science is heard so often in modern times that almost everybody has an idea of its meaning. However, its definition is difficult for many people. The meaning of the term is confusing, but everyone should understand its meaning and objectives (目标). Just to make the explanation as simple as possible, suppose science is defined as classified knowledge or facts.

Even in the true science, distinguishing fact from fiction is not always easy. For this reason great care should be taken to distinguish between beliefs and truths. There is no danger as long as a clear difference is made between temporary and proved explanations. For example, hypotheses(假设) and theories are attempts to explain natural phenomena. From these positions the scientist continues to experiment and observe until they are proved or discredited. The exact status of any explanation should be clearly labeled to avoid confusion.

The objectives of science are primarily the discovery and later the understanding of the unknown. Man cannot be satisfied with recognizing that secrets exist in nature of that questions are unanswerable; he must solve them. Toward that end, specialists in the field of biology and related fields of interest are directing much of their time and energy.

Actually, two basic approaches lead to the discovery of new information. One, aimed at satisfying curiosity, is referred to as pure science. Sometimes practical-minded people miss the point of pure science in thinking only of its immediate application for economic rewards. However, one should remember that the construction of the microscope had to come before the discovery of the cell. The host of scientists devoting their lives to pure science are not apologetic about ignoring the practical side of their discoveries; they know from experience that most knowledge is eventually applied.

The other is aimed at using knowledge for specific purposes--for instance, improving health, raising standards of living, or creating new consumer products. In this case, knowledge is put to economic use. Such an approach is referred to as applied science.
