从人类刚开始进入太空到现在,只有四十年的历史,然而,太空研究却出现了翻天覆地的变化。说到科技进步,自然要归功于无数辛勤工作的科学家。不过,事实上,科技进步也离不开工程人员的贡献。世界上著名的航空工程师卡尔曼说过:科学家努力理解事物的根本,而工程师则创造过去从来没有存在过的东西。彼得罗斯基教授是美国杜克大学土木环境工程系主任,他撰写了好几本有关科技发展的书。其中一本书的标题是《铅笔》,他在书中论述了这个简单书写工具
From the very beginning of humankind’s entry into space to the present, it has only 40 years of history. However, the study of space has undergone tremendous changes. Speaking of advances in science and technology, we naturally owe to countless hard-working scientists. However, in fact, scientific and technological progress can not be separated without the contribution of engineers. Calman, the world’s leading aviation engineer, said: Scientists struggle to understand the fundamentals of things, and engineers create things that have never existed before. Professor Petroski is director of the Department of Civil and Environmental Engineering at Duke University in the United States and has written several books on the development of science and technology. One of the books, titled “Pencil,” discusses the simple writing tool in the book
