三百多年前,荷兰有一名制造眼镜的工匠。有一天,他外出办事,他的儿子詹森偷偷地来到了父亲的工作间。詹森看到工作台上摆满了眼镜片,他好奇地把两块眼镜片装进一个筒子的两端,对着桌上的书反复观看。他发现,书上的字和标点符号突然变大了。父亲回来后,看到詹森的发现,就重新制作了一个镜筒。这个筒子可以自由伸缩,能看得更清楚了。这就是显微镜的雏型。 More than 300 years ago, the Netherlands had a craftsman who made eyeglasses. One day he went out to work and his son Jansen secretly came to his father’s workshop. Jensen saw the workbench full of ophthalmic lenses, and he curiously put the two ophthalmic lenses into the ends of one of the bowls and watched the book against the table. He found that the words and punctuation in the book suddenly got bigger. When Father came back and saw Jensen’s discovery, he re-created a tube. This bobbin can be freely retractable, can see more clearly. This is the prototype of the microscope.
