Archimedes held the crown in his hand and pondered all day. One day, Archimedes went to the bathroom to take a bath. He stepped into the bath bucket, and when he immersed himself in the bath bucket, some water overflowed from the side of the bucket. Archimedes saw this phenomenon and crackled in his mind. "I found it!" .
Archimedes put an equal weight gold nugget and a silver nugget into a container filled with water, and found that the silver nugget discharged much more water. So Archimedes took a piece of gold equivalent to the weight of the crown and put it in a container filled with water to measure the displacement. Then put the crown in a container filled with water to see if the amount of water discharged is the same, and the problem will be solved.
With further research, Archimedes principle, the most important cornerstone of fluid mechanics, was born.
There is an old monk in Fuzhou Dazhong Temple. He has three disciples. All three monks have gone outside to practice, and now they are back. One student studied poetry in Beijing, and the other learned classics from his elders. Only God praised him and learned nothing. So God praised the old monk and turned him into a handyman.
One day, Shenzan helped the teacher wipe his back in the bathhouse and said, "Although the temple is good, the Buddha in the temple can't." As soon as the teacher turned around, God praised him and said, "Although the Buddha can't do it, there is still light."
One day, the teacher was silently chanting under the window. A wild bee tried to fly out and bumped into a paper window mindlessly. Seeing this situation, God praised and said, "Because the door is open, it is useless to punch the paper window." He also said: "I refuse to leave an empty door. Throwing windows is a big idiot. When can I get ahead? "
So the teacher said, "As your boy said, you have more tolerance, and you will meet a famous teacher. Come on. " God praised the experience of practicing enlightenment under the door of a hundred monks. The monk was ashamed and asked God for help. He cried with joy: "The old monk didn't realize the true mystery of Zen until he was so old."
Reading without seeing a sage is like leading a servant; Officials don't love the people, like thieves in clothes; Lecture is not practice, but a mantra; Don't think about cultivating virtue in your career, but spend it in the present.
Third, there was a man named Tian Zhong in the State of Qi, who was arrogant and unwilling to live in seclusion in the countryside with dignitaries. He thinks it is very wise for him to do so.
There was a man named Qu Gu in the State of Song who went to see him in Tanaka and said to him, "I am a farmer and have no other skills. I can only do farm work, especially grow gourds. Now, I have a big gourd. Not only is it as hard as a stone, but the skin is thick and there is no gap in the gourd. This is a big gourd I left specially, and I want to give it to you. "
Tian Zhong said to Qu Gu: "Gourd can be eaten when it is tender, but not when it is old. Its greatest use is to hold things. Now your gourd is very big, but it is not only thick and seamless, but also hard enough to cut. A gourd like this can hold neither things nor wine. What's the use of it? "
Qu Gu said, "Sir, you are absolutely right. I'll throw it away at once. But, sir, have you ever thought that although you live without others, you live in seclusion here and use all your knowledge and skills, but it is useless to the country? Are you different from the gourd I just said? "
If a person does not contribute his skills to the country and society, but just smiles in the mountains, even if he has a noble reputation, this lifestyle is unwise in essence. Finally, his wisdom and contribution are far less than that of farmer Qu Gu.
