Smith was a landlord. He loved money very much and never gave anything to anybody. Soon he became rich.
One day the weather was fine. There wasn't a cloud in the sky and the sun was very warm. The landlord was walking along a river with his friends, when, all of a sudden, he slipped and fell into it. He cried, “Help! Help!” One of his friends held out his hand and said, “Give me your hand and I will pull you out.” The landlord's head went under the water and then came up again, but he did not give his hand to his friends. Then another of his friends tried but the same thing happened.
Just then a farmer came over and saw all this. He knew the landlord very well. He said to the others, “Let me try.” He held out his hand and said to the landlord, “Take my hand and I will pull you out.” Hearing this, the landlord took the farmer's hand, and in a minute the farmer pulled the landlord out of the water.
All the others got very surprised at this and asked the farmer, “Why did he give his hand to you but not to us?” The farmer said, “You don't know your friend very well, When you say 'give' to him, he does nothing, but when you say 'take' he takes.”

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 is not the tools a scientist uses but how he uses these tools that makes 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 questions and that his answer can be confirmed by other persons. He also works to fit the answers he gets to many questions into a large set of ideas about how the world works.
The scientist’s knowledge must be exact. There is 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 that 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 investigations, and Einstein’s ideas were shown to be correct. A scientist uses many tools for measurements. Then the measurements are used to make mathematical calculations that may test his investigations.
