你见过最小的东西是什么呢?一只小蚂蚁?一颗沙子?或者是一粒小得不能再小的尘埃?就算我们视力再好,这些应该也是我们肉眼能看到的极限小东西了。但是对科学研究来说,这种程度远远不够。在欧洲文艺复兴时期,自然科学得到了很大的发展,第一台光学显微镜就在那个时候诞生了。有了这个神奇的东西,科学家们就像打开了新世界的大门,没事就用显微镜来瞅瞅这,瞧瞧那,发现了很多原来根本看不到的东西。著名的罗伯特·胡克先生就是在1665年用显微镜随便看了看红酒瓶的软木塞, What’s the smallest thing you’ve ever seen? A little ant? A sand? Or a tiny dust? Even if our eyesight is fine, these should be the smallest things we can see with the naked eye . But for the scientific research, this level is far from enough. In the European Renaissance, natural science has been greatly developed, the first optical microscope was born at that time. With this magical thing, scientists are just like opening the door to a new world. They look at it with a microscope and look at it and find many things they could not see at all.
