Chapter 819

"This is a new type of reinforced concrete beam bridge. As a teacher, it's natural to consider everything. If all previous efforts are wasted because of a small mistake, it's not to lose the face of Mohism." Merton said.

The reinforced concrete beam bridge is the first to create the history of the bridge. Merton naturally wants to be perfect. Moreover, with the increasing load of the four-wheel carriage, the importance of the beam bridge will become more and more important. It is self-evident that repairing the beam bridge in advance is beneficial to the Mohist school.

"Unfortunately, the master's knowledge is so broad and profound, but some people don't agree with the master." Wu Mei Niang looked at the shadow of the distant arch bridge and said that she was not worth it to Merton.

Merton smiled and said, "distance is really broad and profound. Not only can it be used in ink technology, but also between people and hundreds of families."

"People can use it among hundreds of families?" Wu Meiniang asked with her glasses wide open.

Merton Lang said, "in Mozi's secret book, an interesting story discovered by the Mohist saint was recorded. You may understand it after listening."

"Mozi's secret?" Wu Meiniang became excited. This is the top secret of Mohism. It has always been mastered by the master. Every story is very philosophical and even hides the secret skills of Mohism. She has been itching for a long time. Unfortunately, she has read the books in the study for a long time, but she still hasn't seen the trace of Mozi's secret, No one thought that Merton would be here to tell her Mozi's Secret works.

"Mozi walked in the state of Zhao and stayed at a hunter's house. The hunter was good at hunting and caught more than a dozen hedgehogs at a time. However, the heavy snow suddenly fell that night. These hedgehogs were shivering all over. In order to keep warm, they had to lean close together. When they got close to each other, they would soon separate from each other because they couldn't stand the long thorns on each other. But the weather was too cold , they leaned together again to keep warm. However, the tingling when they leaned together forced them to separate again. If they were too close, they would be tingled; if they were too far away, they would be uncomfortable with cold. "Merton sighed.

"Ah! What should I do?" Wu Meiniang was still a little girl after all. When she heard that hedgehogs were suffering, she couldn't help worrying.

Merton then said, "in this way, they divided and gathered again and again, gathered and divided again and again, constantly struggling between being frozen and stabbed. Finally, the hedgehogs finally found a moderate distance, which can keep warm and not be stabbed by each other. Only then can they spend a long night."

"These hedgehogs are so clever!" Wu Meiniang said happily.

"When Mo Sheng observed this scene, he couldn't help sighing and saying: near hurts others, far hurts himself, far and near, and tells the distance between people."

"The distance between people." Wu Meiniang looked at the distant arch bridge and thought deeply.

Merton nodded and said, "not only people, but also hundreds of schools. Each of us adheres to his own theory, just like a hedgehog. If the two families are too close, they will quarrel and stab each other. No matter which theory is difficult to support, it needs a hundred schools to unite to explore the endless ocean of knowledge."

"Master speaks highly, disciple understands." Wu Meiniang has an understanding. Mohism and all schools of thought hurt each other like hedgehogs. Some of them can't live without each other. However, it's not the case between the three veins of Mohism. Maybe it's right to keep a distance like this.

Merton looked at the thoughtful Wu Meiniang and said, "since I have taught you the theory of distance of Mohism, I will assign you a task."

"Ah!" Wu Meiniang suddenly looked bitter. Unexpectedly, in the end, the master buried a big pit.

"Why, I don't want to?" Morton snorted coldly. Although he assigned tasks several times ago, Wu Meiniang made a lot of opportunism with the help of Princess Changle. I'm afraid no one helped her this time.

"Please tell me, even if I go through fire and water." Wu Meiniang looked like she would fight and punish.

Merton nodded with satisfaction, picked up a three foot long wooden ruler used by the Mohist children and said, "the ruler is the most accurate distance to measure the distance. Every Mohist child can't leave his hand."

Wu Meiniang nodded solemnly.

"As a teacher, you are required to make a ruler, which must be accurate to centigrade, and the length can be measured at least one foot." Merton asked.

The size units of this era are: one foot, ten inches, ten cents, ten cents. He found that the rulers of this era are too simple. Although the rulers are accurate, the accuracy is not enough. Most of them are accurate to the point, which is the limit. One point is equivalent to three centimeters in future generations. When working, they must rely on the skills of skilled craftsmen to ensure the accuracy, If we can achieve the maximum accuracy, he believes that the children of Mohism will be greatly convenient, and there will be more skilled craftsmen.

"Don't worry, master. I'm sure I can finish it." Wu Meiniang said excitedly. At the same time, she couldn't help being suspicious. This time, the schoolwork is too simple!

Sure enough, Merton frowned solemnly and said, "I think this ruler is too long to carry."

Wu Meiniang nodded deeply. She was also very dissatisfied with the commonly used ruler, which was always in the way.

"If even the three inch ruler is so cumbersome, if you make a ten foot ruler and let the children of Mohism hold it every day, wouldn't Mohism become the laughing stock of hundreds of families?" Merton asked.

"Ah!" Wu Meiniang was stunned there. She realized this problem. The excitement just now had already disappeared.

"Therefore, as a teacher, I require this ruler to be easy to use and carry with one hand. This is your real homework!" Merton solemnly said.

"How is this possible?" Wu Meiniang almost jumped up without hurry. She was clearly a ruler ten feet long, but she asked to control it with one hand. She thought it impossible.

Merton immediately showed a proud smile and said, "this is a good thing for the children of Mohism. As a master sister of Mohism, don't you think you have the responsibility to do it well?"

"But the master also said that distance is immutable. How can a ruler of one Zhang be only as big as a palm?" Wu Meiniang said anxiously.

"Then you need to use your brain. Don't worry. This time, you and my teachers and disciples will make it together like making a mirror. How about a try?" Merton Lang said.

Wu Meiniang was moved. Since the master also made such a ruler himself, it showed that it was feasible. Last time, Merton personally led her to point out the principle of making mirrors. However, this time, I'm afraid she had to do it by herself.

"Yes, disciple!" Wu Meiniang said solemnly with an unyielding momentum.
