Module 4 Great Scientists 【美文阅读】

What makes a person a scientist? Does he have ways or tools of

learning that are different from those of others? The answer is“no”．It isn't the tools a scientist uses but how he uses these tools that make him a scientist.You will probably agree that knowing how to use a power is important to a carpenter.

You will probably agree，too，that knowing how to investigate，how to discover information，is important to everyone.The scientist，however，goes one step further；he must be sure that he has a reasonable answer to his question and that his answers he gets to many questions are into a large set of ideas about how the world works.

The scientist's knowledge must be exact.There's no room for half right or

right just half the time.He must be as nearly right as the conditions permit.What works under one set of conditions at one time must work under the same conditions at other times.

If the conditions are different，any changes the scientist observes in a demonstration must be explained by the changes in the conditions.This is one reason why investigations are important in science.Albert Einstein，who developed the Theory of Relativity，arrived at this theory through mathematics.The accuracy of his mathematics was later tested through investigation.Einstein's ideas were proved to be correct.A scientist uses many tools for measurements.Then the measurements are used to make mathematical calculations that may test his investigations.
