2019-2020年高中英語 Module 4 Great Scientists教案 外研版必修4 【美文閱讀】 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 isnt 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 scientists knowledge must be exact.Theres 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.Einsteins 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. 【誘思導(dǎo)學(xué)】　 Can you list some great scientists?
