Chapter 266 Da Vinci recited Tang poetry and opened up new routes
The large quantities of spices, ebony, sweet potatoes and silver brought back by Zhang Yanling convinced the Ming Dynasty's bureaucrats that the Marquis had really made a voyage.
Moreover, the bureaucrats of the Ming Dynasty also began to have to accept the concept of the earth, and even because of this, more and more people in the Ming Dynasty began to accept this concept.
Especially after the explanation spread that people on the earth did not fall because the earth had gravity.
However, not all people in the Ming Dynasty were interested in paying attention to what this gravity was about and studying why the earth has gravity.
Most people still eat when they should eat and sleep when they should sleep.
Of course, there are exceptions. Wang Wensu is currently struggling with the question of why the earth has gravity.
The wealth of the Ming Dynasty, and the emphasis that Ming Emperor Zhu Houzhao placed on natural sciences such as Han Mohism, enabled Ming scientists like Wang Wensu to have enough energy to study knowledge without worrying about livelihood issues or even life ideals.
Boom!
At the Capital University, in a three-story pavilion with red walls and green tiles, Wang Wensu held an apple in his hand and put it down. The bright red apple fell into a pool of green water downstairs, causing ripples. .
After the water surface returned to calm, Wang Wensu released the identical apple carved from stone. The stone apple fell into the green pool downstairs again, causing ripples.
"People will not fall on the earth because of gravity. Now it can be seen that when objects with different weights fall into the water, the waves caused are obviously different. It can be seen that the greater the weight, the greater the gravity of the earth on the objects. I just don’t know how to calculate this gravity.”
Wang Wensu racked her brains to think, and then tried to throw two mud and stones with the same weight but different volumes into the pool.
There was another thud.
"Goose, goose, song to the sky", Leonardo da Vinci, an international student in the Department of Liberal Arts and Chinese Literature of Capital University, who was over 60 years old, happened to be reciting a Tang poem under the apple tree beside the pond, so he couldn't help but be startled. When he looked back, he saw Seeing that it was Wang Wensu, he just bowed and bowed, and then took the "Three Hundred Tang Poems" published by Hanlin Publishing House in the third year of Zhengde in his hand and prepared to memorize Tang poems elsewhere.
But on the way, Da Vinci couldn't help but sigh in his heart: "In this empire, artists and scientists are really wealthy and can conduct their own research seriously without worrying about hunger."
After Da Vinci sighed, he couldn't help but become more determined to learn Chinese and create art and science in the Ming Dynasty. Therefore, he memorized Tang poetry again: "Goose, goose, song to the sky, white hair..."< br>
Da Vinci found that learning Chinese is quite difficult, especially the ancient poems of the Eastern Empire. He had to pick up the book and read it from right to left again, thinking: "I heard that this poem was written by a Han Chinese named King Luo Bin when he was seven years old. You can write such a difficult poem at the age of seven. The intelligence of the Han people in this empire is really scary! No wonder they can invent so many things!"
Although Leonardo da Vinci thought the Han people were very smart, Wang Wensu didn't think he was that smart. He found that he still couldn't determine the calculation method of force and the earth's gravity. As a mathematician, he felt great doubts about his intelligence. .
Wang Wensu had no choice but to ask Zhu Houzhao again: "Your Majesty, I forgive my ignorance, so I have to take the liberty to disturb Your Majesty. I really can't find a way to calculate the force. In this way, I can't be sure how to calculate the gravity of the earth. Please give me some advice!"
Zhu Houzhao understood Wang Wensu's doubts very well. After all, it was still the twelfth year of Zhengde, and the founders of classical physics such as Galileo and Newton had not yet appeared. It was still the era of geographical discovery and the development of astronomy. Even Copernicus had only proposed the heliocentric theory. Just four years have passed, and Bruno has not been born yet. It is naturally impossible for Wang Wensu to think of all the calculation methods in classical physics at once.
"This is not difficult," Zhu Houzhao said smoothly.
"Isn't this difficult? I've been thinking about it for a long time and still can't come up with a solution!" Wang Wensu thought in his heart, and then he held up his hands and said, "Please give me some advice, Your Majesty!".
"In that case, let me ask you first, are you sure what force is related to?" Zhu Houzhao asked.
"I can confirm that the heavier the object, the greater the force generated when it falls from the same height," Wang Wensu said.
"That's enough. If you think so, you can think of the force as being proportional to the weight of the object. This proportion means that the greater the weight of the object, the greater the force. Then you can create a symbol to express it, such as something like so".
Just like teaching a junior high school student, Zhu Houzhao wrote F∝m on the rice paper with a brush: "This means that force is proportional to weight."
Zhu Houzhao had already introduced Arabic numerals, Latin letters, and some special characters needed in natural science to Capital University. Therefore, Wang Wensu was no longer unfamiliar with this formula at this time, and just nodded obediently.
"Then you set a coefficient, represented by g. You assume that g multiplied by the weight is the gravitational force exerted by the earth on the object. Isn't it F=mg? Then you can just know that the weight of the object and this g are How much does it take to know how powerful it is?”
When Zhu Houzhao said this, Wang Wensu suddenly realized: "Your Majesty is wise!"
Zhu Houzhao just smiled faintly. He didn't think this was so difficult. After all, a middle school student could master it in later generations. However, he could also understand why Wang Wensu was so shocked. After all, this way of thinking was very difficult for the Ming Dynasty people of his era. It is indeed a great inspiration. After Wang Wensu was inspired by Zhu Houzhao, he knew that all he needed to do now was to measure g. However, because of this, he was even crazier than before he found Zhu Houzhao and began to think about how to measure g.
When Zhu Houzhao found out, he was very supportive and said that if Wang Wensu needed help, he could go directly to the academic department, and the academic department was not allowed to shirk the responsibility.
However, Zhu Houzhao did not directly tell Wang Wensu what the acceleration of gravity is. He wanted Wang Wensu and other Ming Dynasty people to calculate it themselves. The significance of this was not only to let the people of the Ming Dynasty know the answer to the acceleration of gravity, but also to let them know. How to find the answer.
After the concept of the earth was deeply rooted in the people of the Ming Dynasty, Xia Yan and others wanted to let the Ming Dynasty seize global resources as soon as possible, while Wang Wensu thought of studying more in-depth physics. Zhu Houzhao not only supported the former, but also supported the latter. He knew that waiting for Galileo Newton It is impossible for these figures to establish classical physics after they are born. Ming Dynasty's own scientists must personally establish various laws in natural sciences such as physics and mathematics.
Wang Wensu is still working hard to determine the earth's gravity (gravity), while Xia Yan and Zhang Yanling have now arrived at Haojing in Xiangshan County (Hong Kong) in Guangdong and Guangxi in the early spring of February of the 13th year of Zhengde.
Now Haojing has become the shipping center of the entire Nanda Minghai Sea.
Every year in May and June, there are countless official or private Ming Dynasty sailing ships carrying raw silk, cotton cloth, silk cloth, soap, glass, high-carbon steel knives, and springs purchased from the mainland. In May and June, they take advantage of the monsoon to transport them to Japan, then exchanged these goods for silver, and took advantage of the monsoon to return to Haojing after November.
In Daming, with the promotion of mechanical spinning industry, the cost of raw silk, cotton and silk cloth has been reduced to extremely low levels. Soap, glass, high-carbon steel knives, springs and other items are considered high-tech products in this era, and only Daming can produce them. Production, so the profit from selling to Japan is very high.
Basically, the profits are above 100%, and some are even as high as 200%.
The Ming Dynasty's merchant ships made more than two million taels of silver from each trip every year.
Of course, in the past, this route was controlled by Xiaofangji (Portugal).
However, after the Ming Emperor agreed to Lin Tingxuan to open sea in Guangdong and Guangxi, and organized and trained the navy, which is now the navy, especially after the Ming Navy completely wiped out the Xiaoflangji fleet that attempted to occupy Malacca (Malacca), this route It belongs to Ming Dynasty.
From Japan to Manchuria, basically only the ships of the Ming Dynasty exist in the entire Daming Sea.
Now with the opening of Haojing, this route has officially become a fixed route from Haojing to Nagasaki, Japan.
However, with the opening of Songjiang port, the future route to Japan will undoubtedly change from Shanghai County, Songjiang Prefecture to Nagasaki, Japan, so Haojing's shipping status will undoubtedly be affected.
Officials in Guangdong and Guangxi, who had reaped the benefits of trade due to the opening of Haojing as a port, were very worried about this. Wang Hong, the governor of Guangdong and Guangxi, even repeatedly petitioned the imperial court not to open Songjiang to the sea.
Of course, Wang Hong could not stop the court's decision.
Therefore, as soon as Songjiang opened as a port, officials from Guangdong and Guangxi became more anxious. When Xia Yan arrived at Haojing, Wang Hong and other officials from Guangdong and Guangxi immediately asked Xia Yan what he could do.
Xia Yan also thought of a way first, and the way was to open up a new route.
"Colleagues, Hao Jing's dominant position in going to Japan may be replaced by Songjiang Mansion in the future, but this does not mean that Hao Jing will decline because of this. Now I am here to serve Hao Jing with His Majesty's will. Do you know what is the biggest advantage of Guangdong and Guangxi in opening up new routes? ”
Xia Yan asked.
Officials from Guangdong, Guangdong and Guangxi hurriedly said in unison: "Please make it clear, sir!"
"The advantage of Guangdong and Guangxi is that we have Haicheng Port in Malacca in our hands. We can open a route from Haojing to Haicheng and then to India, and bring India's pepper, iron ore, copper ore, sappan wood, and sandalwood." Incense, ivory, and musk are shipped back to our country, especially the ore. Our country is short of ore now
In order to protect the Feng Shui of our Ming Dynasty (protect the environment and ecology) and reserve resources, His Majesty the Emperor, coupled with the opposition of some stubborn ministers to quarrying, the ore within the country cannot be mined casually, and the ore from abroad can only be transported back first! This is what our officials and people in Guangdong and Guangxi need to do. I believe that just this one route will allow us to collect taxes from Guangdong and Guangxi no less than the current amount. What’s more, in the future, we can also go to Cape Verde along Goa, India. If you transport the gold and silver mines back, you will earn more by then! ”
When Xia Yan said this, all the officials from Guangdong and Guangxi present smiled happily. Wang Hong even laughed first and said: "Of course it is. As long as the court is willing, if this route is opened, gold and silver will definitely come in like running water. What will happen to our officials and people in Guangdong and Guangxi?" Worry about the lack of money!”
