1.What is the main idea of the passage
2.Which scientists are mentioned in the passage
It talks about the importance of scientific experiments and the way of thinking in science.
Roger Bacon, Galileo Galilei, Thomas A. Edison, Isaac Newton.
3.How many parts does the passage have, and what is each part about
Structure:Two main parts.
Part 1: The importance of scientific experiments (using Roger Bacon and Galileo Galilei as examples).
Part 2: Science as a way of thinking (using Thomas Edison and Isaac Newton as examples to explain methods like trial-and-error).
The importance of scientific experiments
People generally believe that modern science started in the Middle Ages with Roger Bacon. Bacon was a wonderful scientist and philosopher from Oxford. He lived from 1214 to 1292. He believed that we must learn science by observing and experimenting on the things around us. He himself made many important discoveries this way.
Galileo Galilei lived about 300 years after Bacon. He was the greatest of several great men in Europe. He discovered many important truths through careful observation. Before his time, people like Aristotle thought that heavier objects would fall faster than lighter ones. One day, Galileo decided to run an experiment. He went to the top of the Leaning Tower of Pisa with two different-sized balls. He dropped them both at the same time. He proved to his friends and other scientists that the balls fell at the same rate. Galileo believed that people should go out into nature and prove their opinions and theories by experiment. This belief led to many great discoveries of modern science.
Science: a way of thinking
Many scientists, from their earlier work, have enough knowledge to make good guesses as to the solution of a problem they are working on. In making new discoveries, they may use the trial-and-error method, they may draw on past experiences, or they may try to find out what others have discovered. They may design new investigations and new ways of testing their results. Scientists have to train themselves to use their brains efficiently; that is, they train
themselves to think.
For example, when Thomas A. Edison was trying to make an electric lamp, he needed a substance for the filament inside the bulb that would glow brightly without burning up quickly. He tried more than a thousand different filaments before he found one that he could use. After each trial, he thought about how each new substance reacted. He kept notes and compared the results. After he had experimented for a long time, someone asked him if he was discouraged by all the wasted time and failed experiments. He replied, “I have not been wasting time. I have found one thousand materials that won’t work. Now I can look for others.” Edison’s statement is all-important.
Scientists spend many years studying and training themselves to use their brains and tools to investigate nature and the workings of the world. They also build upon each other’s work. Isaac Newton, a British scientist, who lived over 300 years ago, said he saw further than others because he stood on the shoulders of giants.
