When Li Yu finished writing his thesis, Yi Kuang also came back. He went in, changed into casual clothes, and called Li Yu over.
"Let me ask you, you said yesterday that the earth revolves around the sun because of this universal gravitation, so why don't they collide with each other?"
Good guy, this prince is actually quite studious.
Li Yu then explained to him: "Your Majesty, it's because our earth revolves around the sun very quickly. You may not know that this speed is as high as 30 kilometers per second, ah... that is 60 miles per second. "
"Sixty miles per second?" Yikuan couldn't understand this concept at all. He took out a pocket watch and asked, "Are you talking about one second when this little hand moves?"
"That's right, just like that," Li Yu also deliberately paused for a second, "it's 60 miles away. It's almost like running around the outer wall of Beijing and 10 miles more."
"Impossible!" Yikuang shouted, "Absolutely impossible!"
Yikuang's voice really looks like Cao Cao in the emoticon.
Li Yu had no choice but to patiently explain: "Your Majesty, this really happened. You can ask any Western teacher, and they will definitely say the same thing."
"But after running around the outer city in such a short time, how could I not know or feel it!" Yi Kuang really couldn't understand, "It's unreasonable! It's unreasonable!"
Li Yu thought to himself, you will find it unreasonable a lot in the future, but since I am called Li Yu, I will definitely make you "reasonable".
He transformed into a popular science teacher and explained the mechanical principles to Yi Kuang in detail. Of course, they were all very simple.
Yikuang felt like his head was going to explode: "Don't go around so much now. I have to give an answer to Rong Zhongtang tomorrow, so just tell me simply."
"I see, this is easy to handle." Li Yu finally realized that it was not Yi Kuang who was eager to learn, but that this 13 was not fully pretending.
He found some paper and wrote down Newton's formula, and he made a lot of numerical deductions, which made Yikuang's eyes pop out.
"Can you still use a foreign pen?"
Li Yu turned the pencil in his hand skillfully: "This? It seems that envoys often use it."
Yikuang felt that he had really invited a treasure, and his skills were not bad, "But even if you write so much, I can't understand it."
Li Yu suddenly realized that he had forgotten to translate the numerical symbols with words, so he had to write them in words next to them.
Of course, Yi Kuang still couldn't understand, so Li Yu said: "You only need to show these two pieces of paper to Master Zhongtang and tell him that you have deduced them yourself. If he still doesn't understand, it won't be the prince's problem."
"good idea."
What Yikuang wants is this effect, Newton or not, without delaying his own earning of money.
The words written in pencil were too small for Yikuang, so he picked up a magnifying glass and copied them again. This time, Ronglu would definitely be speechless.
After finishing it, Yikuang asked someone to bring the globe: "Look at this again. I got it from the Queen Mother. Help me point out where the United States is hanging upside down."
The globe was given to the Queen Mother by the wife of the Dutch minister a few years ago. Although the accuracy of the globe is very different from that of later generations, the general outline is still there.
Li Yu once again transformed into a geography science expert and taught Yi Kuang common sense about geography. Fortunately, through serving as a minister of the Prime Minister's Yamen, Yi Kuang had some understanding of this, and his geographical knowledge was not difficult to accept.
Li Yu mainly taught him the concept of distance so that he could know how big the earth was. This knowledge alone was enough for him to digest for one night.
The next day, Li Yu found Ding Hailiang with his manuscript on X-rays.
When Ding Haoliang saw it, he was completely confused: "Did you write this?"
"Yes, what do you think?" Li Yu said.
Ding Hailiang read it carefully for a long time. Although he did not understand the complicated partial differential equations in Maxwell's equations, the whole paper seemed very smooth and well-founded, and verification methods were also given.
The key is that it is very novel, even if it is checked for plagiarism, it will still pass the test.
Definitely an excellent paper!
Ding Hailiang praised: "It is completely publishable. Your article has reached a very high level."
Li Yu said: "That's good. What changes do you think need to be made?"
"No need at all, I can't change a single word in it. And I really didn't expect your English calligraphy to be so good."
"Hey! It's not because of the college entrance examination!"
"College entrance examination?"
"I mean, to prepare for the school exam practice." Li Yu quickly explained.
Ding Haoliang gave a thumbs up: "I really admire the Chinese people in calligraphy!"
He took out a piece of paper and continued: "According to the regulations of Western universities, students who publish papers in journals need the signature of their supervisor. The university has not started yet, so I will sign this for you. In addition, you also need to write A letter of introduction.”
Li Yu said: "Thank you very much, Professor Xi."
It's quite troublesome to publish a paper now, but it was much more convenient in Li Yu's time.
Ding Haoliang took out a Parker pen and quickly wrote a letter. His handwriting is not as beautiful as Li Yu's, but he actually developed his skills through exam-oriented education...
What Li Yu is most coveted is the pen in Ding Haoliang's hand. This thing is now in short supply. If it were later, the pen in his hand would be auctioned for at least 10 taels.
"Let's go." Ding Haoliang picked up the pile of manuscript papers and prepared to go out.
"Where to go?" Li Yu asked.
"To send a letter, of course."
The Qing Dynasty just opened the Qing Post Office in 1896, which was initially affiliated with the Customs. Hurd, the General Department of Customs and Taxation, also serves as the General Postal Department and is under the control of the Prime Minister's Yamen.
However, when the other powers saw that an Englishman had become the Customs and Excise Department and also the Postal Department, they naturally became jealous.
This is a super delicious pastry!
The Qing government had no choice. In order to reconcile the "contradictions" between imperialists, it arranged a "General Postal Office" position under the General Postal Department in 1901, and it was held by Frenchman Bo Li. The postal power actually fell into his hands. In French hands.
Of course, it was also because Hart's customs revenue was higher and he was really too busy.
The funniest thing is that in the Qing Dynasty, people are rushing to eat their own meat, and they have to act as peacemakers to divide the meat!
The reason why countries attach so much importance to the postal service is definitely not because they really want to help the Qing Dynasty make money. Their inner calculations are very loud!
Let’s take a small example to understand: In 1902, the post office in Shanghai discovered that a package contained morphine worth up to 3,000 taels!
In addition, precious metals, jewelry, pearl necklaces, etc. are all available.
With this thing as a cover, they can smuggle secretly and avoid customs taxes and inspections.
You have ulterior motives!
