一个苹果从树上落下,一般人习以为常,但却唤起了牛顿的好奇心,他苦苦探索,发现了万有引力。一只装着葡萄球菌的培养器里,由于空气不断侵入,球菌表层周围生了一圈绿色的东西,附近的球菌也不见了。这是日本细菌研究者古在由直最早观察到的现象,但被他视为常见的一般的细菌污染而轻易放过了。可是,当法国细菌学家弗莱明观察这一现象时,就产生了强烈的惊奇感。他追根溯源,做了大量实验,终于证实那一绿色的东西是一种能吞噬葡萄球霉菌的新的素霉——青霉素,因而获得了一九四五年诺贝尔奖金。在科学发展的历史
An apple falls from the tree, which is used to by ordinary people but evoke Newton's curiosity. He painstakingly explores and finds gravitation. In an incubator filled with staphylococci, a circle of green was formed around the surface of the cocci due to constant air intrusion, and nearby cocci disappeared. This is the oldest observed phenomenon by Japanese bacterial researchers, but easily overlooked by what he sees as a common general bacterial contamination. However, when the French bacteriologist Fleming observed this phenomenon, he had a strong sense of wonder. He traced the source, did a large number of experiments, and finally confirmed that the green thing is a new prime mildew that can swallow Staphylococcus globosum - penicillin, which won the Nobel Prize in 1945.
