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．

　　1．What makes a scientist according to the passage？
