Here, as soon as He Yun left Liu Jin's study, the voice of Prince Zhu Houzhao came over. He looked very excited, as if something happy had happened.
Zhu Houzhao walked over excitedly with something the size of a face plate in his hand, and when he was approaching Liu Jin's study, he covered it again.
"Your Highness~"
Looking at Zhu Houzhao's appearance, Liu Jin suddenly laughed.
After all, he was still a child. Although Zhu Houzhao in history is now an emperor, Emperor Hongzhi cured his intestinal carbuncle and his health is getting better and better. It is estimated that Zhu Houzhao may have to be a prince for several more decades. Of course, he has no idea about being an emperor.
He has no interest in it, I guess he would be happy to be the prince for the rest of his life.
"Old Liu, guess what is in my hand?"
Zhu Houzhao carried the thing in his hand to Liu Jin, and at the same time blocked it with his own clothes, and asked slightly mysteriously.
Liu Jin looked at this thing as big as a washbasin carefully, thought for a while and said, "What kind of treasure is this, I can't guess."
"Haha, even you can't guess it, that's right."
Zhu Houzhao immediately became happy, and then he opened up the clothes that were blocking him, revealing the cold mechanical shell. He could see some clockwork-like devices next to it.
Then Zhu Houzhao turned it over, facing Liu Jin, and then put the things on Liu Jin's desk.
"This, is this a clock?"
Liu Jin couldn't help but get excited when he saw something. He looked very excited when he looked at the things on the desk, and then looked at them carefully.
To be sure, it is indeed a clock.
It is similar to the clocks of later generations. It is a circle with several hands and corresponding scales. One pointer is constantly rotating. Where the remaining two pointers are pointing, you can clearly see the inscriptions on it.
word.
"Not yet?"
Liu Jin looked at the words on it, and then looked outside. Calculated, it should be almost no time, which is around two o'clock in the afternoon.
"Haha, how's it going?"
Seeing Liu Jin's surprised look, Zhu Houzhao became even happier and said proudly: "Hey, in order to make this clock, I specially studied with several craftsmen from Europe."
"Don't tell me, the Europeans are indeed better than us at making clocks. They were able to make mechanical clocks more than a hundred years ago."
"Referring to the principles they used to make mechanical clocks, I improved them and created the current clock."
"Why do we still use twelve o'clock in calculating this time?"
Liu Jin nodded slightly, looked at the words on it carefully and said.
"The Europeans divide the day into 24 hours. This was first passed down from the ancient Egyptians. Our Ming Dynasty has continued the twelve-hour system. After calculation, one hour for us is equal to two of them.
Hour."
"Europeans like to build large clocks on their churches or large buildings to calculate time. They divide a day into 24 hours, but there are only twelve digits in European clocks. They divide the day into two parts.
Noon is the midpoint, and there are twelve hours respectively.”
"Then an hour is divided into subdivisions. An hour has 60 minutes, and each minute has 60 seconds. Therefore, European clocks have corresponding hour hands, minute hands and second hands."
When Zhu Houzhao heard Liu Jin's words, he began to explain in detail.
"Hmm~"
When Liu Jin heard this, he nodded slightly. This was an internationally accepted method of calculating time in later generations. Unexpectedly, Europeans had figured it out very early.
"One revolution of the second hand is one minute, one revolution of the minute hand is one hour, and one revolution of the hour hand is twelve hours, which is half a day. If it is two revolutions, one day has passed."
"I have to say that Europeans are indeed better than us in this aspect."
"They divided time in detail, and then used mechanical rotation or mechanical swing to calculate time very accurately. In contrast, in the past, we only calculated time based on clepsydras, hourglasses, or sundials, although roughly
They can all know the time, but they cannot know the time as accurately as the Europeans."
When he said this, Zhu Houzhao couldn't help but praise.
In the past, I always felt that the people of Ming Dynasty were the best in all aspects, but since coming into contact with some European craftsmen, Zhu Houzhao also discovered that Europeans are quite powerful in many fields.
"Europeans have made great achievements in mathematics, mechanics, physics, chemistry and many other aspects. There is a lot worth learning from us. Recently, I have been studying European Latin and learning their language. I feel that in the field of mathematics, we will continue to
We can introduce some Latin letters or create some new concise numbers, which will be more conducive to the research and development of mathematics."
"I have studied the mathematics of Europeans. They use a combination of Arabic numerals and letters. Many mathematical formulas are clear at a glance. We like to use language to describe it, which is not conducive to the understanding and development of mathematics."
Zhu Houzhao thought for a while and continued.
He said it very seriously. He is a genius in many aspects and is a master in learning foreign languages. He even learned the language and mathematics of Europeans and was able to see their advantages and his own shortcomings.
This made Liu Jin on the side widen his eyes slightly.
This Zhu Houzhao is indeed a genius. Except that he is not suitable to be an emperor, he can do anything.
“Is Latin easy to learn?”
Liu Jin looked at Zhu Houzhao and couldn't help but ask.
"Easy to learn, easy to death~"
"Let me tell you, even though there are many countries in Europe, each country has its own language, but in fact they are not very different in essence. They basically all change around the Latin alphabet. More than 20 letters change
It's changed, but the combination and pronunciation are different."
"As long as you master the core things, no matter how you change it, it's actually the same. I can already speak Spanish, Portuguese, French, and Italian now."
Zhu Houzhao said without hesitation: "It's true, Europe is not too big. It's a bigger place, but there are many countries. Each country has its own language and writing. Why is there no one to unify it?"
Europe uses the same language and writing."
"These are all Latin alphabets. They are essentially the same. They are also produced in more than ten or twenty languages."
"sharp!"
After listening to Zhu Houzhao's words, Liu Jin gave him a thumbs up.
He remembered his fear of being dominated by English when he was in school before time travel. Unexpectedly, for classmate Zhu Houzhao, he said it was very simple. In just a short time, he had already mastered several languages of European countries.
You have to throw it away when comparing goods. Comparing people with people is very annoying.
This guy likes to learn things from foreign countries. Before he broke up with the Europeans, he was already proficient in Tibetan, Sanskrit, and even learned the Mongolian language. It is said that it was for the convenience of conquering the grasslands in the future, and he also learned Arabic from others.
people.
Now I'm learning European languages again. The key is that this guy is very talented in languages. It's actually very easy to learn. Do you think it's irritating?
What's even more annoying is that even if he just learns it, he can still see the advantages and disadvantages of the other party's language, writing, mathematics and other fields, and he still needs to introduce and learn from them.
Sometimes after being in contact with this guy for a long time, Liu Jin had to sigh, there are really geniuses in this world, and the gap between people can really be so big that it makes people feel desperate.
"I have studied the history of Europe. The geographical environment of Europe is actually much better than that of China. Logically speaking, they should be more of a country. But not only have they not become a country, they are also very divided."
"Looking back at China, our geographical conditions are actually not as good as those in Europe, but throughout our long history, we have always been divided and united, and in the end we were able to unify."
"I think the actual reason may be the relationship between language. Although everyone in the Ming Dynasty speaks in his own words when speaking, and if we are far apart, we can't understand what the other person says at all, but we all use the same language.
"
"It is this kind of writing that firmly connects us. Although the words are different, the words are the same, and we have a sense of identity with each other."
"Europe is different. Although they all have more than 20 letters, each country's speech and words are different. Over time, each country has little sense of identity, so it is difficult to become one country."
"However, Europe, the Middle East, and Tianzhu are actually similar. They do not use language and writing as a link, but religion as a link. This is very different from us."
Hearing Liu Jin's praise, Zhu Houzhao smiled even happier and began to talk about his discoveries and research again.
"Your Highness is truly a genius, so knowledgeable and talented, so admirable!"
Liu Jin admired Zhu Houzhao very much, and he didn't mean it as a compliment, but because of Fazi's inner admiration.
The conclusion he reached is highly similar to the conclusions reached by some experts and scholars in later generations, which is admirable.
"Haha, I think so too, I am a genius!"
When Zhu Houzhao heard this, he was so happy that his tail was raised. Then he looked at the clock on the table and said.
"I learned from European clock-making technology, combined it with our existing Ming technology, improved it, and created this clock."
"I divided the day into twelve hours, one hour and two hours, one hour and sixty minutes, and one minute and sixty seconds. I used the rotation of mechanical gears to drive and the mechanical spring to provide power, and created this history of our Ming Dynasty.
