     What is the nature of the scientific attitude, the attitude of the man or woman who studies

and applies physics, biology, chemistry, geology, engineering, medicine or any other science?

     We all know that science plays an important role in our societies. However, many people

believe that our progress depends on two different aspects of science. The first aspect is the

application of the machines, products and systems of knowledge that scientists and technologists

develop. The second is the application of the special methods of thought and action that scientists

use in their work.

     What are these special methods of thinking and acting? First of all, it seems that a successful

scientist is curious - he wants to find out how and why the universe works. He usually pays

attention to problems which he notices have no satisfying explanation, and looks for relationships

even if the data available seem to be unconnected．Moreover, he thinks he can improve the existing

conditions and enjoys trying to solve the problems which this involves.

     He is a good observer, accurate, patient and objective and uses the facts he observes to the

fullest. For example, trained observers obtain a very large amount of information about a star

mainly from the accurate analysis of the simple lines that appear in a spectrum(光谱).

     He does not accept statements which are not based on the most complete evidence available．

He rejects authority as the only basis for truth．Scientists always check statements and make

experiments carefully and objectively.

     Furthermore, he does not readily accept his own idea, since he knows that man is the least

reliable of scientific instruments and that a number of factors tend to disturb objective investigation.

     Lastly, he is full of imagination since he often has to look for relationships in data which are

not only complex but also frequently incomplete．Furthermore, he needs imagination if he wants

to guess how processes work and how events take place.

     These seem to be some of the ways in which a successful scientist or technologist thinks and

acts.
