Levenhuk was always so in love with books that the lamp burned his hair from time to time. In order to save lamp oil, he always dialed the light so small that his eyes became more and more nearsighted. The high myopia of his eyes made him wonder if he could have a pair of magnifying mirrors! With such a mirror, people would be able to see more natural phenomena, such as where the chirping of crickets comes from and how the ears of rabbits are constructed. This novel idea was so firmly attracted to him that he finally made up his mind to build a pair of magical "treasure mirror".
Next door to the grocery store was an optician's workshop, which Levonhuk visited whenever he could. When he talked to the old craftsmen about the idea of making the mirror, they were amazed by his whimsical and strange ideas. They ground the lenses day and night, but none of them had ever seen such a "precious mirror". They looked at the young man's solemn look, know that he is not joking, one of the old man thought for a moment and said: "I do know such a thing: last year, my little grandson to my grinding of two convex lenses stacked on top of each other, to see that his hair is as thick as a small wooden stick, and he saw the eyes of the fly and the same as a barbed-wire fence. But I haven't the leisure to ask about that number!" Words are not intended, the listener has a heart, listen to the words of the old man, Levin Hooker seems to have a sense of enlightenment, so he made the "precious mirror" determination is greater, more confident.
One morning, Levin Hooker finally ground into a small and exquisite convex lens. He put a chicken feather under the lens, really magnified a lot, that a root of fluff are like twigs as neatly arranged. Then he sharpened another piece of the same lens, and, according to the old craftsman, overlapped the two lenses and adjusted the distance. This was the first human microscope. With it, people have a "magic eye".
Levenhuk began to use his microscope to observe some very small things, such as the blood vessels in the rabbit's ear, the cricket's wings, the fibers of wool and so on. Everything was so new that he could hardly believe that what he saw in the mirror was seen with the lenses he had sharpened. Levenhuk kept observing, kept recording, every day there is a new and strange discovery.
