也许会有人觉得,科普对于我们是一个有它不多,没它不少的东西。或许还会把它纳入只有投入,而没有产出的东西。可你有没有想过,科普有时会在世界历史重大转折的岔道口,居然会成为历史的扳道工?而且,每当世界历史行进到一个新的非常重要的岔道口的时候,科普就会出来,充当扳道工的重任。在这里,我想讲一个人、一段历史和一个故事。 Some people may think that popular science for us is a small, it did not have a lot of things. Perhaps it will be included only into the input, but not output of things. But have you ever wondered if science popularization will sometimes turn into a historical switchman at the fork in a major turning point in the history of the world? Moreover, science popularizes whenever world history moves to a new and very important juncture , As the key task of switchman. Here, I want to talk about a person, a history and a story.
