我是研究科学的人,所以我想谈谈实验精神在科学上的重要性. 科学进展的历史告诉我们,新的知识只能通过实地实验而得到,不是由自我检讨,或哲理的清谈就可以求到的. 实验的过程不是消极地观察,而是积极地、有计划地探测.比如,我们要知道竹子的性质,就要专门栽种竹子,以研究它生长的过程,要把叶子切下 I am a research scientist, so I want to talk about the importance of the experimental spirit in science. The history of scientific progress tells us that new knowledge can only be obtained through field experiments, not by self-review or philosophical talks. The process of experimentation is not passive observation. Instead, it is actively and systematically detecting. For example, if we want to know the nature of bamboo, we must specialize in planting bamboo to study the process of its growth and to cut the leaves.
