During the reign of Emperor Guangwu of Han Dynasty, a great plague broke out in Huiji, and more than 10,000 people died in a few days. In the face of this tragic scene, the county magistrate Zhong was on pins and needles. He kept blaming himself: "The people are in trouble and I can't save them. What kind of parents are they! " Regardless of the risk of infection, Zhong went door-to-door to express condolences to patients and their families, and ordered to recruit doctors with huge sums of money to develop new drugs.
A few days later, a new drug was developed, but I dare not give it to the patient immediately, because there are some toxic herbs in it, and I don't know if it will bring side effects. At this moment, Zhong said to him, "Isn't this very simple? Let me try. "
Say that finish regardless of everyone's stop, reached for the medicine and drank it. After he drank it, there was no sign of poisoning, so he distributed the medicine. Soon, the plague was under control, and Li Zhong's frowning brows stretched out.
2.edison
Edison can be said to be the greatest inventor in the19th century, and his name is associated with a series of brilliant achievements. But behind his success, he actually experienced many failed attempts. 1877, Edison began the experiment of transforming arc lamp. In order to achieve satisfactory results, it is necessary to find a filament that can withstand the high temperature of 2000 degrees 1000 hours or more.
Edison began a difficult search process. He has done 1600 different experiments and tried various substances. After nearly five or six months' struggle, it is found that only platinum is more suitable, but platinum is more than Huang Jingui, so it is not practical to use it as a filament.
Later, he devoted himself to carbonization, and there were more than 6,000 kinds of carbonization experiments on plants alone. He made more than 200 notes, reaching more than 40 thousand pages. It took three years for Edison to develop a satisfactory bamboo filament until the first half of 1880.

4. Aristotle
Aristotle believes that the speed of falling from a height is proportional to the weight of objects with different weights, and the heavier one must land first. This conclusion was almost 2000 years before Galileo's arrival, and no one had publicly doubted it.
Does the speed of falling objects have anything to do with weight? After repeated observation, research and experiments, Galileo found that if two objects with different weights were dropped from the same height at the same time, they would land at the same time. So Galileo boldly challenged Aristotle's view.
5. Seiji Ozawa
In a conducting competition held in Europe, every conductor was asked to conduct the same tune. It's the turn of Japanese young conductor Seiji Ozawa. Halfway through his command, he suddenly felt that there was something wrong with the score, which made this piece of music sound discordant. So he stopped to point out the mistake. But every judge insisted for sure that there was no problem with the score.
Seiji Ozawa will take command. He came to the discordant place again and stopped again. This time he said affirmatively, "No, there must be something wrong with the score!" " As soon as the voice fell, the judges stood up and applauded him for winning the game. It turns out that the score is everything, which is a trap carefully designed by the judges.
