PFC Chapter 378 The small town of Rome.
Chapter 378 The small town of Rome.
Ye Kun felt even more sad, and forced a smile, "How can it be ten days or eight days? This trip to Jiangnan will take at least more than a month."
Youde smiled slightly: "Then I'll wait for you."
That night, Ye Kun brought Youde back to the palace, asked her to chat with her sister, and spent more time with her.
Two days later, the Roman merchant group brought more than 30 Romans, all of whom were skilled craftsmen, masters of art and thought, or musical masters.
They also brought many books and musical instruments, as well as various measuring tools.
Roman books were made of parchment or papyrus, and also a small amount of silk fabrics, which were all imported from China and were the most valuable.
Ye Kun looked at the Roman books and the cuneiform characters, but he didn't recognize any of them.
The musical instruments of ancient Rome are quite interesting. There are all kinds of strange-shaped pianos, orchestral instruments, and things similar to suona.
Ye Kun rewarded these Romans generously, kept them, and summoned relevant talents on his side to exchange and learn from each other.
During dinner, the Romans were very proud and looked down on Chinese culture.
The translator said to Ye Kun: "The Romans said that the earth beneath our feet is a sphere."
Ye Kun smiled and didn't argue, and ordered someone to bring a globe.
This globe is not accurate, but it has complete longitude and latitude lines, accurate inclination angles, the rough outlines of the seven continents and four oceans, the Tropic of Cancer, the meridian, and the Polar Circle.
There are even some precise coordinates.
Because Ye Kun remembered some of the coordinates, accurate to two decimal places.
When Roman scientists saw the globe, they were stunned.
After a while, the Roman asked, "Excuse me, King of Hanzhong, can you calculate how big the earth is?"
The ancient Romans did measure the equatorial circumference and diameter of the Earth.
They used two poles, placed one in the east and one in the west, thousands of miles apart, and calculated based on the shadows of the sun.
In ancient times, this was quite remarkable.
But in front of a time traveler, it’s nothing.
Ye Kun pointed at the globe and said with a smile: "The ratio of my globe is 1:50 million. If you enlarge this globe 50 million times, it will be as big as the earth."
Then, Ye Kun gave the distance between the earth and the moon, the distance between the earth and the sun, and also gave a brief description of the eight planets in the solar system.
Cheating is different.
The Romans bowed down at Ye Kun's feet: "King of Hanzhong, you are the most learned man in the world!"
But there was one Roman who refused to accept the result and took out several thick books.
Ye Kun took a look and saw many geometric shapes on it.
Damn, Geometry?
This thing is amazing. It was invented by the ancient Greek scientist Euclid hundreds of years before Christ!
After hundreds of years of improvement by Europeans, it was finalized in 300 BC.
It was not until the middle of the Ming Dynasty that it was introduced to China and a Chinese translation was made.
But, only the first half.
The second half of the volume was not translated into Chinese until the Qing Dynasty.
It is indeed the credit of The Elements of Geometry that the foundation of Chinese geometry was laid.
Ye Kun was surprised, but he did not show it. He asked someone to bring a university mathematics textbook and said to the Roman:
"The knowledge in your book is from the works of the ancient Greek Euclid. In China, there was also a famous person a few hundred years ago named Mozi, who knew more. This is the textbook in our school. It is some basic knowledge left by Mozi. You can take a look. There are more profound ones that you cannot understand."
This textbook contains a lot of geometry knowledge and was written by Ye Kun based on his memories.
The knowledge difficulty level is above junior high school and below high school.
The Roman mathematician looked at the pattern above and his face turned pale.
The levers, pulleys, and various geometric shapes above let him know that he had met his match.
Ye Kun took the opportunity to brag a bit, pointing at Geometry's Elements and saying, "I don't think anyone in your country, Rome or Qin, can fully understand this book, right?"
Geometry was originally very profound, and it contained many conjectures that could not be proved at the time.
Although the Romans inherited some of the cultural heritage of ancient Greece, Ye Kun felt that they might not fully understand the Elements of Geometry!
The Romans asked back: "King of Hanzhong, can you fully understand the above knowledge?"
"I can." Ye Kun nodded and said:
"You stay here and exchange and learn with each other. When you translate the book, I will explain each question to you one by one."
The Romans were all excited and nodded in unison.
Ye Kun ordered the construction of a small Roman city covering an area of 20 acres on the flat high ground outside Xiangyang City.
Let the Romans design it themselves and provide the materials and workers ourselves.
Craftsmen and scientists were also sent to participate and learn the Roman architectural art.
After its completion, the Romans could live there with peace of mind, communicate with each other, and translate Roman works.
I heard that the Romans were very skilled in building houses with stones, and Ye Kun also wanted to see it for himself.
In addition, Ye Kun also rewarded the people of the Roman Merchant Group and asked them to bring more Roman technicians and other talents over in the future so that he could use them all!
Bring someone with expertise here and they’ll give him a cartload of porcelain with a clearly marked price.
Xue Changfeng was puzzled and said with a smile: "My lord, our country of Dading is full of talented people, and hundreds of elites are thriving. Why do you regard these ugly foreigners so seriously?"
Ye Kun sighed: "There are four ancient civilizations in the world, and our China is just one of them. The mathematical theories and philosophical theories of Rome and Qin are very powerful."
Xue Changfeng was stunned: "What is philosophy?"
Ye Kun thought for a moment and said, "It is a philosophical study. For example, a broken piece of wood will never dry up, which is philosophy. For example, a rush growing among hemp will stand straight without support; white sand will turn black with it. This is also philosophy."
"This thing is philosophy? Then we have too many Chinese people, why do we need the Romans?"
"This……"
Ye Kun didn’t know how to answer!
Indeed, philosophy is of no use to ordinary people.
It can’t be eaten as a meal!
As long as the common people have enough food to eat, they don’t care about your philosophy!
Xue Changfeng was afraid that Ye Kun would be embarrassed, so he smiled and said, "Mathematics is still somewhat useful. Craftsmen can use it..."
"More than a craftsman." Ye Kun smiled.
"Last time, Yizhou predicted the solar eclipse by using mathematics. The Romans also had experts who could use mathematics to predict solar and lunar eclipses."
Xue Changfeng smiled awkwardly: "Since the Romans are useful, then they can stay. It's nothing more than eating some rice."
Ye Kun patted Xue Changfeng on the shoulder and said, "General Xue, if you have time, you can also talk to the Romans. Learn about their tactics and weapons and equipment."
Xue Changfeng was stunned: "My Lord, do you mean to attack Rome and Qin?"
Ye Kun smiled and said, "Didn't you say that after the Nine Provinces are unified, we will expand overseas territories?"
"I was just kidding..."
"But the Romans are not joking." Ye Kun sighed and pretended to be troubled:
"Last time, the Roman tycoon Crowe brought me a letter. The monarch of the Roman Empire wants me to surrender. Otherwise, he will send three million troops to attack China!"
"Three million troops? How many people does the Roman Empire have?"
"At least 60 million, and possibly hundreds of millions at most."
"How many times more than our Great Ding Kingdom?" Xue Changfeng was shocked: "Then how can we defeat them?"
Ye Kun continued to scare Xue Changfeng: "So I treat these Romans well, just to understand their situation in Rome. Knowing yourself and the enemy will ensure victory in every battle, don't you understand?"
