About science 关于科学
The importance of scientific experiments 科学实验的重要性
People generally believe that modern science started in the Middle Ages with Roger Bacon. 人们普遍认为，现代科学始于中世纪的罗杰・培根。
Bacon was a wonderful scientist and philosopher from Oxford. 培根是牛津大学的一位杰出的科学家和哲学家，
He lived from 1214 to 1292. 生于1214年，卒于1292年。
He believed that we must learn science by observing and experimenting on the things around us. 他认为，我们必须通过对周围事物的观察和实验来学习科学。
He himself made many important discoveries this way. 他本人就是通过这种方式取得了许多重要的发现。
Galileo Galilei lived about 300 years after Bacon. 伽利略・伽利莱生活的年代比培根晚大约300年。
He was the greatest of several great men in Europe. 他是欧洲众多伟大人物中最杰出的一位。
He discovered many important truths through careful observation. 他通过仔细观察发现了许多重要的真理。
Before his time, people like Aristotle thought that heavier objects would fall faster than lighter ones. 在他之前，像亚里士多德这样的人认为，较重的物体下落速度会比较轻的物体快。
One day, Galileo decided to run an experiment. 有一天，伽利略决定进行一项实验。
He went to the top of the Leaning Tower of Pisa with two different-sized balls. 他带着两个大小不同的球登上了比萨斜塔的顶端。
He dropped them both at the same time. 他把它们同时扔了下去。
He proved to his friends and other scientists that the balls fell at the same rate. 他向朋友们和其他科学家证明，这两个球的下落速度是相同的。
Galileo believed that people should go out into nature and prove their opinions and theories by experiment. 伽利略认为，人们应该走进大自然，通过实验来验证自己的观点和理论。
This belief led to many great discoveries of modern science. 这一信念促成了现代科学许多伟大的发现。
Roger Bacon (1214-1292) English philosopher and scientist 罗杰・培根（1214—1292）英国哲学家、科学家
Galileo Galilei (1564-1642) Italian astronomer, physicist and mathematician 伽利略・伽利莱（1564—1642）意大利天文学家、物理学家和数学家
Culture Tips 文化小贴士
Galileo Galilei is often referred to as the "father of modern science" because he made great contributions to the fields of physics and astronomy. 伽利略・伽利莱常被称为“现代科学之父”，因为他对物理学和天文学领域做出了巨大贡献。

Science: a way of thinking 科学：一种思维方式
Many scientists, from their earlier work, have enough knowledge to make good guesses as to the solution of a problem they are working on. 许多科学家凭借早期研究积累的知识，足以对正在研究的问题的解决方案做出合理的推测。
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. 在进行新发现时，他们可能会采用试错法，可能会借鉴过去的经验，也可能尝试查阅他人的研究成果。
They may design new investigations and new ways of testing their results. 他们可能会设计新的研究方案，并探索验证结果的新方法。
Scientists have to train themselves to use their brains efficiently; 科学家必须训练自己高效地运用大脑；
that is, they train themselves to think. 也就是说，他们要训练自己如何思考。
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. 例如，当托马斯・爱迪生试图制造电灯泡时，他需要一种既能明亮发光又不会迅速烧毁的物质作为灯泡内的灯丝。
He tried more than a thousand different filaments before he found one that he could use. 他尝试了上千种不同的灯丝，才找到一种可用的。
After each trial, he thought about how each new substance reacted. 每次试验后，他都会思考每种新物质的反应情况。
He kept notes and compared the results. 他做笔记并比较结果。
After he had experimented for a long time, someone asked him if he was discouraged by all the wasted time and failed experiments. 经过长时间的实验后，有人问他，是否因浪费了大量时间且实验屡屡失败而感到沮丧。
He replied, "I have not been wasting time. 他回答道：“我并没有浪费时间。
I have found one thousand materials that won't work. 我已经找到了一千种行不通的材料。
Now I can look for others." 现在我可以继续寻找其他材料了。”
Edison's statement is all-important. 爱迪生的这番话至关重要。
Scientists spend many years studying and training themselves to use their brains and tools to investigate nature and the workings of the world. 科学家们花费多年时间进行研究和自我磨练，以便运用自己的头脑和工具来探索自然和世界的运行规律。
They also build upon each other's work. 他们还相互借鉴彼此的研究成果。
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. 300多年前的英国科学家艾萨克・牛顿曾说，他之所以能看得比别人更远，是因为他站在巨人的肩膀上。
