A way of thinking

Many scientist from their early work haven't enough knowledge to make good guess as the solution of the problem they are working on . they making new discoveries they may use the trial and early messages .they may drop on past experience or they may try to find out what others have discovered . They may design new investigation and new ways to test their result. Scientist have to train theirselves to use their brain efficiently ,that is train theirselves to think .For example, When Thomas.A.Einstein was trying to make an electrical ( ), He need a substance for a () inside the bulb . that would grow bright without burn up quickly. He try more than a thousand different () before he found one that he could use . After each try, he thought about how the new substance had acted . He kept noted and compare result. After he had experiment for a long time, someone asked Mr. Einstein if you were not discourage at the waste time . He replied , "I have not waste time, I have found one thousand materials won't work and now I can look for others .Edison stamen is all important ,above all ,scientist demand to know when or where they are wrong ,A good question to ask in science is not "am I right "but "am I wrong "~ scientist spend many years of study training themselves to using theri brain. And the truth is investigation, They also use each others work. Newton ,a british scientist ,who lived over 300 years ago ,He said he saw further than others because he stood on the shoulder of giants .
