Chapter 390 The Origin of the Difference Engine 【6200, please order】

"Brothers, I'm out of customs!"

"I'm out!"

Around nine o'clock at night.

In the No. [-] restaurant.

When Class [-], who had finished their day's exploration, had a rare dinner together to brag about what they had seen and heard, the door of the restaurant was suddenly pushed open roughly.

Niu Pu rushed into the restaurant with an extremely excited spirit, and was pulling a cart behind him, on which was the difference engine that he had studied for many days.

The sudden loud noise immediately startled everyone in Class Nine, but when they turned their heads to prepare for a wave of words, they were momentarily at a loss.

They looked at each other, then at Niu Pu, and suddenly felt like laughing.

Yes, want to laugh.
Their immediate attention was not on the difference engine behind Niu Pu, but on his head.

In their impression, although Niu Pu has long and fluttering hair, no matter how the hairline is, it can be regarded as complete.

but now.
How does the other party's hairline look like the pictures of programmers on the Internet?

Is it a bit too far back?

After a while, everyone couldn't help laughing anymore.

In an instant, the originally silent restaurant was full of joy again.

Niu Pu blinked blankly: "You guys."

"What laughing?!"

Hearing this, Li Cheng suppressed his smile and asked with concern: "No."

"Brother Niu"

"Isn't our hairstyle a bit too strong?"

"Don't you feel a little cold on your forehead?"

Hearing this, everyone in Class Nine immediately covered their mouths, their shoulders shaking non-stop.

No, you can't laugh too loudly, you have to save some face for Niu Pu.

This guy has been in seclusion for such a long time, he can't be ridiculed when he comes out!
Seeing this, Niu Pu's face darkened immediately, and he put the hood behind him on his head without saying a word.

Fortunately, he was wearing a hoodie today, otherwise it would be very difficult to end.

Immediately, his complexion darkened, the tip of his tongue pressed against his teeth, and his dantian screamed Hunyuan Qi, roaring angrily:

"Is there something wrong with your focus?"

"I told you that I was out of customs, and you actually asked me if my forehead was cold?!"

"Is this the question I'm talking about?!"

"Is this the point?!"

"Shouldn't you ask me why I left customs?!"

Hearing this, everyone in Class Nine looked at each other in dismay, shook their heads after a while, and blinked innocently:
"Should it?"

"I think compared to that thing behind you."

"We should care more about your body."

"After all, we are dear relatives and friends, brothers and sisters~"

So you have to pay more, right? Niu Pu's face darkened again.

Now he really wants to give these bad friends a set of military boxing immediately.

But just when he was planning to implement the plan, Ren Yan came forward to stop this happy atmosphere:

"Okay, okay, don't talk nonsense."

"Niu Pu wants to come and share the results with you, so you have to give him face first no matter what you do."

"Cooperate with other people's performance~"

"That's right~" Niu Pu nodded in agreement.

Seeing this, everyone in Class Nine was no longer making fun of it. After the joy in their hearts passed, they asked seriously:
"So, what did you find out?"

"Can it excite you like this?"

"The specific function of this difference engine!" Class [-] asked, and Niu Pu answered immediately.

While speaking, he also pushed the difference machine behind him to the front, full of a sense of accomplishment:

"This difference engine wants to calculate astronomy!"

"astronomical?!"

As soon as this remark came out, everyone in Class Nine immediately became interested, and they couldn't help but put the dinner they were enjoying back.

Originally, they thought that this thing was for calculating a large number, although it looked full of technology.

But in fact, the level of technology is limited, at most it is the function of an electronic calculator, and it may even be far inferior.

After all, you can't count on a bunch of mechanical gear structures to calculate something earth-shattering.

Not to mention, the age of this thing is likely to be hundreds of years ago.

Therefore, after the initial freshness passed, they were not very interested in this difference engine.

If Niu Pu didn't want to study it, they might have handed it over to the country long ago.

But now, they were really surprised.

No matter how much they know about astronomy, they still know one thing very well.

It is the calculation amount of this thing, which is definitely an astronomical figure, otherwise this word would not have appeared.

Think about it, the distance between celestial bodies is tens of thousands of light years, even with the current computing power, that is definitely a huge number.

Not to mention the complicated movement of celestial bodies.

All these variables are added together, and even electronic computers are always at risk of being scrapped.

But now Niu Pu said that this thing is calculating astronomy? !
After a brief surprise, Class Nine subconsciously couldn't believe it.

"Are you sure this thing is for calculating astronomy? Are you mistaken?" Ah Wei opened his mouth and asked with a frown.

"Absolutely!" Niu Pu nodded earnestly, and then waved his hand, signaling everyone in Class Nine to come closer.

After everyone who should have gathered around and those who should stand on stools stood on stools, Niu Pu began to tell the whole process of his reasoning:
"I understand your surprise. I was also surprised when I realized this."

"But unfortunately that's the truth."

"First of all, the first information this thing gave us was the numbers 235 and 127."

"Following these two numbers, I looked through a lot of historical books, and finally found these two numbers in astronomy books."

"So, these two numbers have a special meaning?" Wang Bo asked.

"Yes, these two numbers represent a piece of astronomy handed down from ancient Greece." Niu Pu nodded:
"In those days, the ancient Greeks determined the time by looking at the moon."

"The cycle of the moon's waxing and waning is 29.5 days, which is called a synodic month in astronomy. There are 354 days in twelve months, which is 11 days less than our current solar calendar."

"The ancient Greeks would make up for the missing 11 days by means of a leap month."

"However, their method of intercalary months is different from ours now. In the astronomical books of ancient Greece, it is recorded that they observe that every 235 synodic months equals 19 solar years."

"The 235 also corresponds to the number engraved on the gear."

"I think it's about one cycle of this gear, which corresponds to the overall cycle of the blue star, the moon and the sun, 19 years."

While speaking, Niu Pu tried to shake the large gear, but due to the severe corrosion, the gear didn't move at all.

"Then what about the 127 you mentioned earlier?" Ah Wei asked, "What does 127 represent?"

"That's actually 254." Niu Pu shrugged:

"This thing is on top of gears, and the gears mesh with each other, so we should multiply by 2."

"Similarly, some Greek astronomical books also record that one revolution period of the moon is 27.3 days."

"19 years is exactly the revolution period of 254 moons. Although there will be some deviations compared with the present, I feel that this deviation can be ignored in the thousands of years of history."

"So this thing is used to simulate the cycle of a blue star, moon and sun? That is a lunar eclipse?!"

Wang Yu, who had been thinking for a while, suddenly spoke out, his eyes frightening.

As one of the few people in Class Nine who was slightly interested in this thing, he also paid attention to it at the beginning.

But I didn't expect the computing power of this thing to be so scary.

"Yes, but this is only a part of the whole machine." Niu Pu smiled.

"Part of it?!"

"That's right, because I also found the largest gear behind this machine. Although it has been corroded too badly, I still found its parameters after careful cleaning."

As he spoke, Niu Pu adjusted the difference machine at an angle, exposing the back of it to everyone in Class Nine.

Immediately, he pointed to the back that had been completely cleaned:
"See that number? 223."

"This represents the number of teeth of this big gear."

"In the records of Sumerian civilization, 223 months happens to be a cycle of total solar eclipse."

"So, this thing can also calculate solar eclipses? Then who is his maker?!"

After Niu Pu finished speaking, Wang Bo also became shocked:
"More than two thousand years ago, not only did you know the astronomical knowledge of Greece, but also the astronomical knowledge of Sumer?! It's a bit outrageous!"

"You've hit the point here. I was messy at first, but it wasn't until I saw these words."

Niu Pu glanced at Wang Bo appreciatively, and then pointed to the notch on another gear with his white glove:
"Although these nicks are severely worn, they are still faintly visible after cleaning, and I confirmed that these nicks are a kind of writing."

"A script handed down from thousands of years ago, the Corinthian script, which means moon."

"Collins?! Where is this? I've never heard of it." After speaking, Xu Kai who was not far away raised a question.

Niu Pu immediately gave the answer:
"Collinth, according to legend, is the son of Zeus 8000 years ago. The city built by Corinthus has advanced technology."

"It is said that there are still robots with unknown energy sources living in the city."

"They generally have knowledge that is ahead of their time."

"It's just that due to unknown reasons, the city was destroyed, and the Corinthians in the city went their separate ways."

"And among these descendants of Collins, there is an exceptionally famous person."

"This man is a physicist, mathematician, inventor, architect, and astronomer, known as the hundred-armed giant Archimedes."

After a short explanation, Niu Pu sorted out his thoughts and wanted to continue to add this explanation.

But everyone in Class Nine was completely stunned, but after a brief blank mind, they swallowed their saliva involuntarily.

"Wait, wait, don't rush to explain later."

"Tell us first, what is the son of Zeus? Greek mythology?!"

"You, a historical relic, have risen to the level of mythology, isn't it somewhat unscientific!"

"Also, what the hell is Archimedes!"

"Isn't this the guy who invented the buoyancy formula?"

"As if we were tortured enough by the buoyancy, we even took a look at this person's life."

"If I remember correctly, he lived in more than 200 BC!"

"It's less than 2000 years from now!"

"You mean, more than two thousand years ago, the ancients were able to make bronze gears?! Still so regular?!"

"That's why I said that this thing is an anachronistic relic."

Niu Pu sighed slightly, ready to explain slowly.

But the moment he spoke, Ren Yan laughed lightly:
"When studying culture or history, don't be influenced by the titles of some documents."

"Myth, and at some point maybe the history of some way of recording things that went wrong."

"For example, the Great Flood. There are similar records all over the world. Our Dayu controlled the water, and Noah's Ark in the West, but these are all classified as myths."

"If it is really a fabricated story, can it really achieve such a high degree of unity across several oceans?"

"There will always be unknown things in it."

"For another example, if we record the current technology and show it to some civilizations that are completely different from our civilization model, what will they think of everything that happened in our era?"

"Not to mention, there are some things that you may not be able to say."

"Therefore, in mythology, we must also maintain a heart of bold assumptions and careful verification. This is the correct way to explore a period of history."

"Niu Pu has such thinking, which shows that he still has something."

After all, Ren Yan gave Niu Pu an encouraging look.

Everyone in class nine around nodded silently, always feeling that their brains had been artificially opened up a little bit.

"Okay, Niu Pu, you continue."

Seeing that everyone in Class Nine was a little relieved about this question, Ren Yan nodded at Niu Pu.

Niu Pu immediately began to explain the following questions:

"My point of view is the same as what Teacher Ren said."

"As for the thing you questioned later, it came from more than two thousand years ago, this is a better explanation."

As he spoke, Niu Pu took out a few coins from his pocket:

"This is the coin we salvaged with the difference engine."

"After observation and comparison, I have discovered the period they belonged to. Almost all styles are small country currencies around 200 BC."

"It's just that these small countries were all wiped out by Rome."

"In the same period of time, there was also a war between ancient Rome and ancient Greece. In that war, there was the shadow of Archimedes."

"Or the whole war was a war between ancient Rome and Archimedes alone."

"It is recorded in history books that when ancient Rome was besieging the city, Archimedes made all kinds of strange equipment to help defend the city."

"What cranes and catapults were all made by Archimedes."

"In the end, ancient Rome used the tactics of encircling and not fighting to consume ancient Greece."

"Then this just shows that this thing was indeed made 2000 years ago, but how can you be sure that it must have been built by Archimedes?" Li Cheng asked with a tangled expression:
"The descendants of Collins should not be alone in Archimedes."

"Of course~" Niu Pu smiled: "In fact, in the end, I was sure that what Archimedes built must not only be of the same age."

"There is also important historical evidence."

"According to ancient Greek literature, Archimedes once built a machine that used water power to calculate the movement of celestial bodies, but this machine disappeared later."

"At the same time, that thing is huge in size, and it is definitely not the one we got."

"But at least it shows that it is possible that Archimedes once built the same thing."

"The other piece of testimony comes from ancient Roman documents."

"According to their records, the emperor of ancient Rome sent his general to attack Greece. In the end, the general captured two machines that could demonstrate divine power. One was handed over to the emperor, and the other was kept privately by the general."

"I thought that in ancient times, something that could calculate solar and lunar eclipses must be considered divine power."

"With this thing, the emperor can represent God's will even more. He is someone who can accurately predict solar and lunar eclipses, so what will his subjects think of this emperor?"

"And in addition to this guess, there was a poem recorded by a poet in ancient Rome at that time."

"In the poem, he also mentioned this machine, and explained that the one he had seen the general was used to calculate celestial bodies."

"Of course, his poem cannot be regarded as a real historical document, it can only be used as a testimony."

"But don't you think that with so many testimonies combined, the answer is already on the surface?"

"As for how it ended up on a pirate ship and appeared in the Bering Strait, it's probably because the poor general was robbed later."

After all, Niu Pu smiled again, feeling that his performance was perfect this time!
Telling this magnificent story clearly and clearly made him feel a sense of accomplishment.

In fact, Class Nine is really impressed by the current Niu Pu.

No wonder people's hairline has moved back, it has really become stronger.

So much trivial information was actually integrated by him abruptly, and it sounded reasonable.

This, anyway, they can't do it.

Thinking of the literature that Niu Pu mentioned just now, they felt overwhelmed.

"Grandson, how many books have you read during this time?"

"There is one more question." After a short moment of emotion, Xu Kai, a pragmatist, silently raised his hand: "What's the use of making such a thing more than [-] years ago?"

"Purely for domination?"

"Probably more than that." Hearing this, Niu Pu shook his head, and guessed: "At that time, it was still in the farming civilization, and the common people depended on the sky for their food."

"I think having such a machine that can calculate the time of day will be very helpful to their production."

After listening to Niu Pu's completely self-consistent logic, everyone in Class Nine was completely silent, and fell into a deep shock.

Then they looked at Ren Yan, wanting to hear their teacher's opinion.

However, Ren Yan just shrugged: "I only know that this thing is probably astronomical calculations, but who made it, I have no idea at all."

"But now that Niu Pu gave the whole clue very clearly, I think it should be pretty close."

Listening to their teacher's words, everyone in class nine silently turned their eyes to Niu Pu, and looked at the difference machine in front of him.

Class Nine gave Niu Pu a thumbs up:

"Awesome, boss!"

"We are convinced!"

"That's right, we won't talk about your hairstyle anymore, this is the proof of being strong!"

Hearing the praise from Class Nine, Niu Pu was flattered at first.

He has been busy for so long, pretending to be big and knowing that unknown period of history, he is very happy.

But after hearing what the students said later, Niu Pu's face darkened instantly:
"Are you finished!?"

"Can we stop worrying about my hairstyle?!"

After Niu Pu's impotent rage, the atmosphere in Class Nine became joyful again.

Seeing this, Ren Yan slapped her hands: "Okay, don't say these things are useless."

"Now think about how you plan to deal with this thing."

"Niu Pu has fulfilled his wish, this thing is of no use to him."

Hearing this, Niu Pu nodded, agreed with Ren Yan's statement, and then looked at his classmates.

Seeing this, everyone in Class Nine looked at the difference machine again, recalling Niu Pu's analysis just now in their minds.

A difference engine built by the famous Greek Archimedes from 2000 years ago to calculate solar and lunar eclipses
After all these labels were combined, everyone in Class Nine shuddered for no reason.

Any label here feels like they can't bear the weight, and now these fucking labels are combined!
What if this was lost by everyone? !
Is that worth it? !
Therefore, after a very short thought, Class Nine immediately united the front:
"Hand in, hand in, hurry up!"

"This thing is terrible, it's not something we can grasp at all!"

"That's right, let's put it in the National Museum, so we can feel at ease."

"Are you sure?" Hearing this, Ren Yan smiled mysteriously: "If this thing is really what Niu Pu said, its value will be sky-high."

"It may be worth more than Leonardo da Vinci's Mona Lisa, so you just gave up?!"

Listening to Ren Yan's words, Class Nine showed extremely strong reason, and immediately nodded without hitting anyone, even Ah Wei did the same:
"Forget it soon~"

"No matter how much this thing is worth, it is not something we can get our hands on."

"I can't bear it, you know?"

"It's better for us to earn our own money."

After saying that, Ren Yan nodded in satisfaction: "Not bad."

"I didn't lose my sense of proportion because of this little thing, which is worthy of encouragement."

"Then follow what you said and hand it over to the country."

Then Ren Yan changed the subject and looked at Niu Pu:
"But before handing it in"

"Niu Pu, write down all the speculations you just made and the documents you cited, and we will hand them in together."

"Although this thing cannot belong to us, you still need to gain something for your efforts."

"If your speculation is really confirmed, then your kid will probably become famous in the archaeological circle!"

Hearing this, Niu Pu nodded immediately: "Okay!"

Immediately, Ren Yan put a big hand on Niu Pu's hoodie:

"But after that."

"You still care about your hairline."

"I started to lose my hair at a young age, how can I find a girlfriend in the future~"

With that said, Ren Yan looked at everyone in Class Nine.

Class Nine immediately understood: "That's right~"

"No matter how much you like archeology, you have to think about yourself!"

"Look at our class nine, who doesn't have beautiful hair~"

"You will look very out of place~"

After all, Niu Pu's complexion darkened visibly to the naked eye again, and then he became a little slumped.

Since everyone is discussing this issue, shouldn't he really pay attention?
Silently, Niu Pu touched his forehead quietly.

The hairline seems to be receding a bit.
At the same time, in Class Nine, Sun Hao looked at Niu Pu with brighter eyes.
