Chapter 808: On Talent and the Importance of Mathematics (Three in One)
After Wu opened his mouth, most of the people around him spoke in agreement with what Wu said. Especially the second senior brother, who had just swung the hammer for a while, most agreed with Wu's words.
Now in the entire tribe, in terms of strength alone, he has the strongest strength. But just now he was holding the hammer and pounding hard for a long time. His arms were numb from the shock, but he didn't squeeze out a few drops of oil.
Come on, it can be seen that there is really no oil in it.
Moreover, so much oil has been squeezed out of it, enough to fill a basin, and all the oil inside must have been squeezed out.
Han Cheng glanced around and saw that most of the people around him agreed with Wu's views. Those who were not humming could also tell from their demeanor that they very much agreed with Wu's views. Only Yuan remained silent, and some were hesitant to speak.
Look.
"Yuan, do you think there is still oil in this?"
After seeing Yuan's expression, Han Cheng asked in his heart.
During these days, Han Cheng successively taught a lot of mathematical knowledge about circles, and he was able to master simple addition, subtraction, multiplication and division. At this time, looking at Yuan's demeanor, he seemed to have discovered something.
"There should be some oil in it."
After hearing Han Cheng's question, Yuan hesitated and spoke.
Han Cheng ignored Wu and the others' disbelief and surprise, but smiled and asked Yuandao again: "How did you determine that there was still oil in it?"
I asked this question with a vague expectation in my heart.
"that is……"
Yuan said and paused here. After opening his mouth a few times, he didn't think of how to express what he wanted to say. After scratching his head for a while, he suddenly squatted on the ground and found a wooden stick.
, began to write and draw on the ground.
Seeing such a scene, Wu Wu, Second Senior Brother and others were puzzled. Didn't the Son of God ask how he knew the oil was not squeezed out completely? Why were he squatting on the ground and starting to write?
Can you write well?
When Han Cheng saw this scene, the smile on his face became even thicker.
He leaned over to see Yuan writing and drawing on the ground with branches.
The first thing written on the ground by a circle is the multiplication table.
The multiplication table can be written silently according to the order taught by Han Cheng, but it has not yet reached the level of skillful use.
Therefore, when performing calculations, Yuan needs to write down the multiplication table first, and then look at the multiplication table to perform multiplication and division operations.
After writing out the multiplication table, she started to draw division symbols on the ground with branches, then divided thirty-five by five, and compared with the nine-nine multiplication table, she got the result seven.
Then he divided it by five by three hundred and fifty, and after some calculations, he got seventy.
The result of this calculation is correct, but it cannot solve the current problem.
Han Cheng could see the problem at a glance, but he did not ask for advice. Instead, he stood there and looked at the circles that he continued to calculate like a first- or second-grade elementary school student.
After some calculations, Yuan wrote out the last subtraction formula. With the help of counting fingers, after another calculation, he subtracted thirty-five from seventy and got thirty-five.
"Son of God, there is still so much oil in it that has not been squeezed out."
Yuan pointed at the bottles containing tung oil and said loudly.
Before doing the calculation, Yuan vaguely felt that the oil inside had not been squeezed out completely. Later, after hearing Shenzi ask that question, this idea became more convinced.
However, she was not yet proficient in using addition, subtraction, multiplication and division, and could not explain the problem in one sentence, so she squatted on the ground and calculated like this for a while.
Wu, Second Senior Brother, and the others followed the direction of the round finger and looked at the two oil jars, with expressions of disbelief on their faces.
They all saw very clearly that this time a large basin of oil was squeezed out, weighing thirty-five kilograms, and it was all contained in these two jars.
Moreover, the second senior brother who was the strongest just now used a bronze hammer and smashed it hard, but not a few drops of oil came out. Under such circumstances, Yuan actually said that there was still thirty-five percent of oil in this simple oil press.
Of course they wouldn't believe it unless it was squeezed out.
How is this possible?!
"Son of God, is there really so much oil that has not been squeezed out?"
Wu scratched his thinning hair and said loudly, with a hint of confusion.
He didn't believe it at first, but when Yuan said there was still oil in it, Wu became a little unsure.
After nearly a year of living together, as Wu got to know Yuan better and better, he came to know that Yuan is a very smart woman.
Although what she said at this time did not sound true at all, Wu still murmured in his heart.
Especially when Yuan was squatting there just now, holding a branch on the ground, writing, counting, and counting on his fingers, and mumbling words, it looked very realistic and very bluffing.
When Wu asked, the others, including Yuan who was feeling a little uneasy, all looked at Han Cheng.
Han Cheng smiled and shook his head and said, "There's not that much oil."
As soon as these words came out, Wu, the second senior brother and the others immediately breathed a sigh of relief, especially the second senior brother, who even burst into tears. Let's just say, his arms were numb from the shock just now, and he had to use all his strength.
It's over. How could there be so much oil that hasn't been squeezed out under such circumstances?
There was a tangled and confused look on her round face. According to the calculation method given to her by Professor Shenzi, there were still thirty-five kilograms of oil that had not been squeezed out. Why did Shenzi say there was no oil at this moment?
"It's not as much as the thirty-five kilograms Yuan said, but it's still a lot."
Not waiting for the second brother and the others to be happy for a long time, Han Chengcheng opened his mouth to attack everyone again. After saying such words, he smiled and said to Yuan: "You can do the math again."
Yuan, who was originally full of entanglements and doubts, didn't say too much nonsense when Han Cheng said this. She squatted on the ground and began to carefully check the calculation processes she had just written on the ground.
During the process of careful inspection, Yuan would write and draw with the branches in his hands from time to time, with a thoughtful look in his eyes.
After maintaining this state for a while, Yuan's eyes suddenly lit up, he paused for a moment, then he used a branch as a pen and began to calculate in another area.
Different from the slow and hesitant way when I checked just now, the writing speed of the round one is much faster this time, and the whole operation process seems much smoother.
"Son of God, it's fifteen pounds, not thirty-five pounds!"
After doing this calculation for a while, Yuan, who was squatting on the ground, suddenly raised his face, looked at Han Cheng and said with surprise.
Han Cheng looked at her approvingly, nodded vigorously at her, and said with a smile: "Yes, it's fifteen pounds!"
When saying these words, Han Cheng also gave a thumbs up to Yuan.
Yuan, the female priestess of a former semi-agricultural tribe, is indeed smarter than the average person. There are always professors in the tribe for things like mathematics. Most people in the tribe can do addition and subtraction well, but when it comes to multiplication and division, then
I was immediately blinded.
Among the remaining people who can perform multiplication and division operations, another large part of them can just calculate numbers on paper, but they cannot apply them to daily life to solve practical problems.
But Yuan, a female priest of a once semi-agricultural tribe, has been exposed to mathematics for a short period of time compared to most people in the tribe, just over two months. As a result, she has been able to apply it to solve practical problems.
.
Today's series of calculations, in addition to addition, subtraction, multiplication and division, actually involve some proportional issues.
Although Yuan didn't understand much about this, he independently calculated the correct result.
Although the calculation was wrong the first time, it is already very rare.
After all, she has not been exposed to mathematics for a long time, and the actual application is much more difficult than simply calculating numbers.
Sure enough, mathematics is a subject suitable for smart people, and talent is really important in many cases.
When the people in the tribe do hard work, most of them are good at it and are not afraid at all, but when it comes to various knowledge, many people become weak.
Chinese characters are better. After all, people are still very interested in these studies due to the attraction of popular Qingque Tribe classics such as "Tadpole Looking for Mom" and "Monkey Fishing for the Moon".
But mathematics, which is more abstract and requires memorizing many rules, is really a pain in the head. Even the best stone in the tribe is still scratching its head when it comes to mathematics. Even now, it is still scratching its head.
If you only know the four simple arithmetic operations, you will not be able to understand or learn them if you go to advanced levels.
In this whole tribe, the stone quality is top-notch.
Now that he has discovered a good talent like Yuan, Han Cheng naturally cannot let him go and needs to be encouraged.
This will help Yuan better immerse himself in the fascinating world of mathematics and go further and further, laying the foundation for the future development of the tribe.
Han Cheng, who came from later generations, naturally knew the importance of mathematics. Especially after society developed to a certain level, Han Cheng understood even more the role that higher-level mathematics could play in the development of society.
Of course, advanced and complex mathematical knowledge is not needed when buying groceries, but there are many other things in this world besides shopping for groceries.
Han Cheng was really embarrassed that he lost his hair when he first started studying mathematics. However, after working, he rarely used it, but he would not deny the significance of studying mathematics because of this.
Now that Han Cheng has come to this world, he will naturally not abandon him.
People who have been hit on the head by apples say it is easier to pick apples by standing on the shoulders of giants.
Compared with the current tribe, Han Cheng is undoubtedly a giant. If he can leave these things behind, then future generations, based on the foundations he laid, will be able to stand up to others as soon as they are born.
It is very likely that it will be an end point that will never be reached in a lifetime.
Using this as a starting point, you can always go further and make the tribe better.
Of course, these are all many years later.
However, regardless of these future matters, the Qingque tribe also needs mathematical knowledge at this time.
For example, statistics on harvested grain, exchanged furs, etc.
Calculated based on the number of people, how much food does the Qingque tribe need for a year? How long does it take to harvest a road if different numbers of people build it?
How many days can the crops in the field be harvested if everyone works together...
This series of things all require mathematical calculations in order to be well aware of them.
Although there will be errors, they are much more accurate than estimates.
Not to mention the rest, if Han Cheng hadn't calculated that the oil yield was too different in this oil extraction, all the oil contained in the oil residue would have been wasted.
After hearing Yuan say fifteen kilograms and getting confirmation from Han Cheng himself, the second senior brother and others were immediately confused.
Although fifteen kilograms is not as much as the thirty-five kilograms Yuan mentioned before, it is still not a small amount.
You know, this time I only squeezed out a total of thirty-five kilograms of oil and filled two jars.
These fifteen pounds of oil can basically fill a jar!
"God...Son of God, do you really have so much oil?"
The second senior brother looked at Han Cheng and asked with some stuttering.
Han Cheng nodded and confirmed the matter again.
Seeing this, the second senior brother scratching his hair was about to smash the wooden piles again with a bronze hammer, but Han Cheng stopped him.
After some consideration, Han Cheng had roughly figured out why the oil production rate this time was so different from the last time.
This time, more tung oil fruit powder was put in, ten times as much as last time.
Stacking so much tung oil fruit powder together will increase its elasticity and make it difficult to smash it through.
To sum it up in one sentence, you can bite off more than you can chew.
The second senior brother who was stopped by Han Cheng was scratching his hair. Wu, Yuan, who had just calculated that there were fifteen kilograms of oil in it, and more people were scratching his hair with him.
The second senior brother is the strongest among all the people in the tribe. This is recognized by everyone. Now that the Son of God has stopped the second senior brother and prevents the second senior brother from swinging the hammer, how should the remaining oil be obtained?
Of course there was a reason why Han Cheng blocked the second senior brother. The second senior brother's strength could no longer squeeze out the remaining oil. If he could squeeze it out, he would have succeeded before.
At this moment, even if I hold the hammer again and hit it hard, it will be just a waste of effort.
"Son of God, what should we do now?"
Everyone looked at Han Cheng with confusion in their eyes. Even the most powerful second brother couldn't do anything about the remaining tung oil. They really had nothing to think about.
"I have a way to squeeze them out!"
Human beings have limited abilities. They cannot swim like a fish, cannot catch up with a horse when running, and cannot fly in the air like a bird.
However, because people have developed brains, they can create various tools to solve various problems they face.
With the help of intelligence and various tools, one can go to heaven and earth, and dive into the deep sea...
When the human body's own strength reaches its upper limit, then tools are needed.
The tool Han Cheng made this time was very simple, just a battering ram, similar to the one used to strike bells in temples.
However, the piece of wood used as a bumper is larger, longer, and heavier than that used in ordinary temples, and the impact force is correspondingly greater.
"Boom!"
"Boom!"
Han Cheng pulled the rope tied to the battering ram with his hand, pulled the battering ram upwards, and then pushed it back with all his strength.
The battering ram, which contained great power, was under the control of Han Cheng, relying on its own weight, the inertia of swinging in the air, and the force exerted by Han Cheng on it, and it hit the wood hard.
on the pile.
A circle of curious people gathered around.
Everyone chose to believe in this tool created by the Son of God, but there was some disbelief in this belief.
Because the second brother who was the strongest in the tribe couldn't hit it with a bronze hammer, the Son of God, who was not known for his strength now, said that he would use such a tool to knock down the wooden stakes and squeeze out the oil.
Even though they all sincerely believed in the Son of God, under such circumstances, there was still some disbelief in their belief.
However, when the battering ram made of thick wood hit the wooden pile under Han Cheng's control, the onlookers around them all opened their eyes wide. Those who didn't believe it in their hearts, under this impact
, all turned into powder, transformed into surprise and disbelief!
Under this collision, the second brother, the strongest in the tribe, could not smash down the wooden pile with a bronze hammer, but it was smashed in with progress visible to the naked eye.
"Oil! Oil! Oil comes out again!"
While many people were still stunned by such a scene, someone pointed to the bottom of the simple oil press and shouted excitedly.
After hearing this, everyone went to look and saw that the simple oil press, which had been deemed to have no oil before, started to drip oil after Han Cheng pulled the hammer and hit it again and again, and soon it started to drop from one drop to the other.
The drops turned into several thin lines...
It turns out that there really is so much oil in it. It turns out that hanging a piece of wood sideways has such a big impact!
"Come and hit me!"
After Han Cheng pulled the battering ram and banged it for a while, he said to his second senior brother standing aside.
At Han Cheng's signal, the second senior brother stood on the other side of the battering ram, and then worked with Han Cheng on the left and right to pull the battering ram back and raise it, and then push it forward with force.
With the addition of Second Senior Brother, a man of great strength, the advantages of the battering ram have been brought into full play.
With the impact of the battering ram again and again, the wooden pile was smashed in little by little, and more and more tung oil was squeezed out from inside.
"Son of God, this method is so good!"
Seeing that after weighing, the tung oil weighed more than seventeen kilograms, the second senior brother said excitedly.
Using this method, not only can the tung oil be squeezed cleanly, but it is also very labor-saving.
Even though the second senior brother has great strength, when he can save energy, he doesn't want to exert too much force and tire himself out like a lucky general who sticks out his tongue to dissipate heat...
Because the oil press was successfully manufactured and Han Cheng came up with such a labor-saving and efficient hammer, the Qingque tribe seemed very happy.
Those lively and active minors always like to hang out here when they have nothing to do, and they always want to come over and push the battering ram when they have time.
Han Cheng was also very happy. On the one hand, this was because he led the Qingque tribe people to build an oil press from scratch. From now on, there was another kind of machine in the tribe. On the other hand,
That is, the circle is really as he originally imagined, and he is very talented in mathematics.
This is the advantage of smart people. They always make rapid progress in many things that require their brains.
After the success of this large-scale oil extraction, Han Cheng did not let people continue to extract oil. The oil extracted now is enough. The remaining tung oil fruits can wait until winter for oil extraction. After all, at that time
, people in the tribe are more leisurely.
After such a busy time, the autumn mood was still lingering, and the grass around the tribe turned dark green. When I woke up in the morning, the chilly dew clung to the grass blades, making them look completely white.
When people walk by here, dewdrops roll down from the swaying grass blades and stick to their feet, making them feel cold.
The mountains and forests in the distance have also become more colorful. Although it has not reached the point where the mountains and forests are dyed red, it is almost there.
Before we knew it, the late autumn of the tenth year of Qingque had arrived.
In the courtyard, Han Cheng, who was wearing leather gloves, directly dipped a pair of rattan armor into a pottery pot filled with tung oil. After flipping it back and forth a few times, the entire rattan armor was covered with tung oil.
He held the rattan armor in his hand and waited for a while on top of the pottery basin. When there was no more oil dripping from it, Han Chenggong took the rattan armor and hung it on a shelf not far away.
A dozen pairs of rattan nails soaked in tung oil have been hung on this shelf. Under the late autumn sunshine, they are shining with some light and look very beautiful.
"Dong dong dong, dong dong dong..."
Little Pea, who was carried back and forth in the tribe by pandas, held a rattle in his hand and shook it back and forth while grinning like a fool.
The rattle in Xiao Wandou's hand also looks bright, which is much brighter than the dull color before.
This is also due to several layers of tung oil.
However, the rattle was not thrown into a basin of tung oil and soaked in it. Instead, the silk that Bai Xuemei had unsuccessfully weaved was dipped in tung oil and rubbed out. This way, it would not easily leave any traces on the surface and would look more beautiful.
"Tuk tuk tuk..."
This is the sound the cane makes on the stone road.
As the sound got closer and closer, a witch holding a walking stick in one hand and a handful of wild fruits in the other appeared in sight.
It's just that Wu's walking posture seemed very awkward at this time. Every time he walked forward, his body would involuntarily tilt toward the side where he was leaning on the crutches, and the crutches would be extended to a large extent and with high frequency.
It doesn't look like he's walking, but like he's specifically showing off his crutches.
In fact, Han Cheng had this crutch made by Lai Hewu a long time ago, but Wu felt that wearing a crutch would make him look older and would not highlight the strength of his body, so he left it there and never used it.
However, since Han Cheng soaked the crutch in mint juice for a few days, dried it, and wiped it several times with an unsuccessful silk cloth dipped in tung oil, the witch couldn't walk without this crutch.
