In fact, the article is also very simple. It tells the story that Edison was very clever when he was young. Once his mother was ill and called the doctor. The doctor found that he had appendicitis, so he decided that he needed surgery. However, because there was no electric light at that time, there was only kerosene lamp, and its weak light was not enough for surgical lighting. Just then, Edison had a brainwave and ran out to find his friends. He put kerosene lamps on the edge of the mirror, and the lights of several kerosene lamps were reflected by the mirror, which instantly lit up the bedroom. Only in this way can the operation go smoothly and his mother be saved.
In fact, this passage is nothing, but it has such a positive educational function, but it is wrong to think about it carefully. First of all, the operation should be carried out in a sterile environment, but in a room with kerosene lighting. Edison's mother is bound to become inflamed after the operation and is more likely to die directly. Secondly, this thing must be fake, because Edison's appendicitis was not cured when he was young, but Edison invented the light bulb long ago when appendicitis was cured. What's more, we always believed it. The teacher taught us to be realistic and couldn't even do the textbooks we didn't want to learn, which made us students who had studied for so long how to deal with typos.
