The appropriate answer made Xiaosheng reminisce for a long time, and praised: "You always have a deep meaning in doing things, and I can't do it." ”

Holding a bamboo slip with the names of several people written on it, he said on the side: "You are naturally inferior to him, but you are not as good as me." When I was asked to write down the names of those people, I guessed. Sure enough, what he said is right, to do righteousness, you must first know what righteousness is, and then you can know whether what you are doing is in line with the general righteousness. ”

"For example, this matter is all mutually beneficial, and it is also for the benefit of the world, without falling into the righteousness of my Mo family, and it can broaden the hearts of everyone."

"Just as I know that I want to go to Chudi, I don't necessarily have to go south first. Maybe I want to go west to get around the rapids and go south...... Only by knowing the purpose can we know whether what we are doing is beneficial or harmful to the world. ”

Xiaosheng rarely did not refute the words of the contempt Qi Sui, and even nodded in agreement, which caught the scorn Qi Sui off guard, and almost let the bamboo slip in his hand fall to the ground.

Seeing that he had the intention of speaking again, he hurriedly said, "Go back with me to see the giant first, and report this matter to the public." Qi Sui, you take the first step, first tidy up the bamboo slips, and Xiaosheng and I will go directly to Mr. ”

…………

More than ten days later, the ink artist was in the workshop of Shangqiu, and it was very hot.

The workshops are in the middle of the city, and there are a lot of open spaces in the city, and there are even many vegetable fields and farmlands. But at this time, the land in the city was already extremely expensive, and being able to have such a place in the city shows that the Mo family was deeply rooted in the Song Kingdom.

After the development of Su Qin in later generations, when his sister-in-law groveled to him, he once sighed: If Lao Tzu had two acres of land on the edge of the city, how could he work hard to hang the seal of the six countries? So he spent all his money to motivate himself to continue to work hard.

It can be seen that the land in the city is expensive at this time.

At this time, the layout of the city is in accordance with the layout of "the scholars are close to the palace, the industry and commerce are close to the city, and the farmers are close to the door".

The workshop of the Mo family was used to defend the city, and it was far away from the city, not close, and far from the place where those craftsmen lived.

At this time, the bazaar was already very developed, and it was no longer as in the "Zhou Li" hundreds of years ago, and the big city had a husband. In a city like Shangqiu, if there is only a market in the land of one husband, it will be squeezed to death, let alone a huge city like Linzi, where the legend raises its sleeves as a cloud and waving sweat beads like rain.

The bazaar is almost the same as the future generations, and all the future generations should have at this time.

"Warring States Policy, Qi Ce" once had the saying "go to the city", which proves that there are stalls to tell fortunes at this time, which is called a long history; "The Analects and the Township Party" once had the saying "The wine market is not eaten", which proves that at this time, there were also people selling wine and dried meat in the market; "Zuo Biography" once had the words "Jin won the Qin spy and killed all the people in the city", which proves that at this time, the prototype of beheading at the entrance of the vegetable market also existed.

Not to mention the existence of those who always hide the swordsmen of the assassins.

It was precisely this situation of industrial and commercial officials that was broken, and the city was no longer just a castle that exploited the surrounding land taxes and labor rents, that allowed the craftsmen who had begun to think about these craftsmen who had gradually gained strength, and had the basis to develop secret ink artists in various big cities by covering their identities.

It was precisely because they knew that the market was wide and profitable, so they joined the craftsmen's guild one after another, and they also gathered in this Moshi's city-guarding equipment workshop to divide labor and cooperate.

In the morning, they exchanged their skills with the axe, and in the afternoon, they were busy together, each with their own division of labor to make spokes, wheels, axles, etc.

There was a fire in it, and the wood was bent with steam or heat to form the wheels.

It's not just the temperature that's hot inside, it's the atmosphere of the crowd.

In just over half a month, the number of military endowments completed has far exceeded what can be made in fifteen days per person, and with a wooden master like Mozi here, he has learned a lot.

In the past half a month, Mozi, Axe Jujin and some ink masters who have learned carpentry have made a model of the small water row.

By solving the problem of crank, connecting rod and belt transmission, the remaining water wheels, horizontal wheels, drums and other components are not difficult in the hands of such carpenters.

The water drain is just the creation of Du Shi during the time of Emperor Guangwu of the Han Dynasty, and there is no insurmountable technological generation gap from this time.

The principle is to use the water flow to drive the horizontal wheel to rotate, and then drive the small wheel, and use the crank and connecting rod to change the rotary motion into transverse reciprocating motion.

Changing the linkage mechanism can be used not only for pushing and grinding, but also directly for pulling the bellows for air blowing in the future. This is the power system, as for what kind of hydraulic machinery to connect, that is a matter for later.

The day before yesterday I had tried it at a stream outside the city that did not freeze, and it worked well, and it was no problem to use it to push the mill to build a hydro-powered mill.

It is still necessary to continue to try to turn the model into a real thing, but it is not difficult to do it again after the specific direction and principle are clear.

After making this thing, Mozi was extremely happy, and according to those disciples who had been with Mozi for a long time, they were even happier than when they fought against the public loss class many years ago.

Perhaps, in Mozi's view, this is a great benefit to people. He is also the most professional carpenter, and often makes bellows and leather lobes in order to defend the city, where does he not know that this thing can be used in smelting?

After being happy, Mozi pondered two small things that were suitable for saying, and they were even more simple things in Mozi's opinion, but no one remembered them.

One is a double-wheeled carriage. The second is a wheelbarrow.

The carriages at this time were all single-wheeled. The front choke and harness are a T-shape, and the horses must be in pairs, on both sides of the T-shape, and the middle crossbar pulls the carriage behind.

Horse-drawn carriages were first used for war purposes, so they needed to be pulled by a horse. On the other hand, in the spring and autumn period, the productivity was insufficient, and those who had carriages were cattle and horses, not worse than this one, and ordinary people did not have cattle and horses.

But now many merchants, craftsmen, and farmers near the cities also needed some wagons and oxcarts, the simpler the better, and they could not afford to use more than two horses.

The wheelbarrow is convenient to use on the impact plains such as Shangqiu.

People who can't afford horse-drawn carts and ox-carts can save a lot of effort by pushing a wheelbarrow in the city, and the cost is not expensive.

In the future, if you are fleeing from the famine, or if you are migrating, having a wheelbarrow can be regarded as a tragic scene unique to the nearby Yellow Flood Area in the future.

I hope that after the appearance of this wheelbarrow, it will only benefit people, and will no longer become an indispensable thing in those tragic memories.

Mozi didn't bother to praise Shi's whimsy anymore, and he didn't even bother to say anything like the ingenuity of this thing, but discussed some technical principles with Shi.

He had studied movable pulleys and fixed pulleys, and he had studied them quite thoroughly, so he took the opportunity to talk to him about some things that Mozi himself needed to name in the "Sutra of Sayings".

Mozi also has the foundation of mechanics, and it is appropriate to follow the logical direction of Mozi to discuss some simple mechanical problems, starting with pulleys and wheels.

Mozi studied the fixed pulley quite deeply: he called it the "rope system", under the fixed pulley, if the two things are equal, then it will be balanced; If the two objects are of equal weight and are at both ends of the fixed pulley, if one is light and one is heavy, it must be light on the inclined plane, and the gravity of the other end of the same is greater than the friction of the equal weight on the inclined plane......

Shi Ben said first: "Mr. Tong rope method, Mr. Sai called it a pulley." Mr. Sai once said that there are two kinds of pulleys, fixed and moving. ”

After a little talk, Mozi understood the difference between moving and fixing the two kinds of pulleys.

"Sir, set pulley, the longer the rope you pull, the more the weight will lift, and the pulling force is equal to the power of the weight, right?"

Mozi nodded and said, "Yes." As you mentioned, you need to pull twice as much rope to lift the same distance, but with less effort. It's the same as the art of taxidermy. ”

The specimen is Mozi's elaboration of the lever. The power arm is called the standard, and the resistance arm is called the foundation.

Shi Yi said: "Since this is the case, then to pull one stone of corn to two feet high, the fixed pulley needs to be pulled two feet with the force of one stone; The moving pulley requires half a stone to four feet. Multiply the two and are always the same. So I thought, we can multiply this number and call it work. ”

When Mozi heard this, he nodded without the slightest disobedience: "The ancients said that merit is determined by labor. Labor, force and time. It's a good name. ”

Shi hurriedly said: "Since this is the case, it can be said that the fixed pulley does not save effort or effort, and the moving pulley saves effort but does not save effort." It's like pushing things on ice, and pushing things on the ground, with the same weight and length, but if the power is different, the knowledge will be different. ”

Mozi likes to define things, and even tries to give a clear definition of many things in heaven and earth.

For example, time, space, circle, force, harm, benefit, optical principle, etc., this habit of liking to define is interesting and useful...... In fact, the basis of geometry and physics is also definition, at least to distinguish between weight and mass.

Dialectics seems useless, but in fact it is very useful, and without a philosophical foundation, it is impossible to define the concept of quality, which is also philosophical and not just physical.

Since he is still alive, he must be triggered to define some more things, as a thing that future generations of ink artists must master.

Mozi didn't know what to think, he looked down at the wheelbarrow that had been made, turned the wheel upside down, and listened to the squeaky sound, as if he had figured out some problems.

For a long time, I don't know what he figured out, I haven't heard Mozi's praise these days, and finally heard Mozi's praise again.

"Suitable, you have made a thing on the flat ground, compared to the shoulder carry, which saves effort and effort!"

He was just about to thank Mr. for the compliment, but when he heard Mozi's next sentence, he was completely stunned.

"You know both strength and skill, and you also know the art of specimen rope making, have you ever learned the theory of light and shadow? I said that the shadow does not move. The bird is moving, the shadow is not moving, in fact the original shadow is gone, and a new shadow immediately appears, not the shadow of the bird is moving. ”

"I look at the bronze water mirror, and I know that the light is transmitted directly, but how fast is this light so that our eyes can't see the shadow disappear and reappear?"

"If our eyes can see things very quickly, what about the moment when the shadow disappears and is formed? If the bird flies very high, and if I am the light downward, will the shadow still be on me? Can I see the shadow of the bird? If the shadow wasn't on me, I wouldn't have seen it, but the bird is indeed blocking the sunlight from the sky...... This is a question that I have been thinking about for many years and cannot solve. ”

Hearing this, Shi shook his head hurriedly, indicating that he didn't know.

It's not that he pretends not to know, but he really doesn't know, how does his half bottle of water know what the disappearance and reappearance of the shadow is like at the speed of light.

Just like the famous dialectical question at this time, whether the arrow is stationary or moving at a certain moment after it flies, is impossible for a person like him to explain.

This is the philosophical problem at this time, and he is not good at it. This question represents the Mohist view of time and space and the continuity and inseparability of time and space, which cannot be explained in a few words.

Mozi sighed and said, "So, it is unimaginable before experiencing something. I've deduced the Promised Land you said dozens of times, and it's all in line with what you said about what it would look like when they appeared. Therefore, I am sure that you must have seen those real objects, otherwise it would be like my question just now, and it would be difficult to think clearly about the shadow of light as quickly without the light. ”

"According to your Paradise Nine Folds, the people of Yao Shun must not have thought of the city at this time. When King Wu divided the Zhou Gong and set the ceremony, he must not have imagined the world at this time. Therefore, there is no immutable truth, only the truth of change, and what seems to be unchanged actually has a premise. ”

"Truth needs to be attached to things, otherwise it is empty talk. If there is no evil gold or straw silk as you said, then the method of selecting the virtuous that you said cannot be used. And if you are at Mr. Sai and Tang Han, and you don't see the real thing with your own eyes, it is impossible to launch a paradise that matches it out of thin air. ”

Listen to the teaching, and praise it in my heart.

Mozi said a few more words and pointed to the wheelwheel: "This thing is beneficial to people, but people may not be able to know." Therefore, when you make wheat flour, you should first make a dozen trucks and stand them next to the city for people to use. Treat people to know its ingenuity, one can broaden the reputation of my Mo family; Second, buying both in the future can also make the craftsman profitable; Three, this is also a scene of paradise, so that more people can understand and imagine the poems you do. ”

"This is what I thought of after seeing you planting those crops in the village community and composing those psalms. If you don't see something with your own eyes, it's hard to imagine the future based on it. ”

Shi did not show much shock at Mozi's philosophical views, but he was very surprised by Mozi's methods.

It seems that every sentence is a righteous act, you can put this thing next to the city for free for people to use, although it is not worth a few dollars, but no one has ever done it, and it is a real thing, everyone can see it, where can Shangqiu City not know the name of the ink man's righteousness?

As soon as this thing comes out, the carpenter and craftsman will have many ways to benefit within a few years, how can they not believe in the inker?

As a result, nothing new will appear for five years, and it will still be impossible for the craftsmen to leave, fearing that similar objects may come out one day after that.

In Shi's opinion, the character who can lead hundreds of ink people to be unrebellious will never be as simple as the stories he knows on paper.

He didn't know how much he was thinking? Or did Mozi just want to make this material profitable? But since Mozi said this, he was in line with his own thoughts, so he said yes and went to prepare.
