Tang Taizong is my elder brother

Chapter 55 The Earth is Round

Luo Changsheng still knew.

The White Horse and Silver Spear, although the ending was a bit miserable, is definitely one of the most popular characters in the Sui and Tang Dynasties.

Changsheng has a good impression of him. If possible, Changsheng would not mind taking him under his command and changing his fate.

But now she has nothing else to do, because the new term of her camp school starts.

Currently the highest grade student in the camp.The youngest is ten years old, and the oldest is thirteen or fourteen.

These people are what she calls 'the first students'.

Changsheng is mainly responsible for their courses.The daily curriculum includes Chinese, arithmetic, geography and physical chemistry.

As a result, it turns out that without the teaching of the modern education system, the instillation of knowledge does not go smoothly.

……

Looking at the bewildered expressions of the children in the audience, Chang Sheng put down the charcoal pencil in his hand: "If you have any questions, you can ask them."

Wang Si, nicknamed "Fourth Brother", raised his hand first. He has grown taller this year.

Changsheng knew him well, and joked, "Get up and talk, fourth brother!"

The fourth child blushed with embarrassment, waved his hands again and again and said, "Master, don't make fun of me. How dare I take it. But I have a question. Is the earth really round? Didn't the books say that the world is a round place?"

"The round sky is the person who wrote the book. Regarding the understanding of the earth, I can't say that he is completely wrong. It's just that the understanding and research affairs at that time were limited by technology. But today, our research methods have improved, so our vision must be wider. open."

"I can only tell you that if you are given a horse that doesn't get tired and you keep riding eastward, one day you will circle the earth and come back from the west, which means the earth is round. yes, right?"

The fourth child didn't answer right away, but thought for a moment before slowly nodding his head: "If what you said is correct, then this will happen, but if the earth is a ball, people who don't stand on it, the head If you don’t rush down, won’t they fall down?”

"This is a good question, which proves that you have thought about it." Changsheng nodded and encouraged him, "But this in itself involves another issue, which is the force in physics. There is a force between everything. There is both a suction and a push, and these forces are sometimes very large and sometimes very small, and you can’t feel them yourself. That’s why I call them gravitational forces, which means that everything has gravitational forces!”

"To understand what you said about people not falling from the earth, we must first understand what is the definition of falling? When the fruit on the tree is ripe and falls to the ground, we call it falling. Rain, we call him rain falling. Now I ask everyone to think about a question, why both rain and apples fall, and finally fall to the ground instead of flying to the sky, or some other direction."

"As long as you understand this, you can understand why people don't fall."

Seeing everyone's wide-eyed and bewildered expressions, Changsheng checked the time and decisively announced the dismissal of get out of class.

The content of today's lecture has seriously exceeded the outline, but since it is here, there is nothing wrong with leaving an after-school homework for them to go back and think about it. Who said that China can't produce Newton or Galileo?
The teaching process itself is also a screening process. During the education process, different children's interests and strengths are discovered, so that they can be assigned to suitable positions in the future and make the best use of them. This is the greatest purpose of Changsheng.

After the relocation, Changsheng spent a little money to get the distribution map of nearby mineral resources throughout the past dynasties.Combined with the memories of her previous life, she roughly understood the distribution of available resource points around her.

Then she can formulate a plan for the possession, utilization and development of these resources.

Of course, these plans are mainly designated by the secretariat headed by Zi Qiao, and Chang Sheng is responsible for reviewing and finally agreeing to sign.

And this time Changsheng finally figured out the name of this cousin named Ziqiao.

Since she was shocked by her second brother last time, she has gotten into the habit of checking out all the people around her first, so as not to miss any important people.

Sure enough, Fang Xuanling, Zizi Qiao!

Fang Mou is right, but I don't know where your other good friend is?
Seeing that his cousin, who was not yet a weak crown, is already doing well in the secretary department, Changsheng also has to admit that the historical inertia is strong!

Soon Fang Xuanling presented the prepared resource mining team personnel structure list.

The team members in the plan must include a geological surveyor who can identify latitude and longitude, geological experts with the ability to identify and measure minerals, guides who are familiar with local customs, language and culture, and medical staff with emergency medical capabilities. Strong security guards with extraordinary skills, and last but not least, diplomats who can negotiate with official families and local aborigines.

This seemingly small team is actually very exaggerated.It is not an exaggeration to say that it is a small special forces unit.

When Changsheng first saw this, he felt that it was enough for them to instigate a coup against a small country.

However, after careful review, she found that it was indeed necessary.

Other candidates are easy to talk about, but who should I choose for this diplomat?Changsheng consulted his subordinates.

Soon everyone came up with a name, Thirteen, that's right, the little boy who was first punished by her, and then stood out and was accepted as a disciple by Master Lu.

Everyone's evaluation of him is: he is alert, sociable, and calm.

Although he is not smooth, his emotional intelligence is definitely enough.

Changsheng thought about it for a while and thought it was okay, so he asked someone to inform him of the news.

So the list of the top-matched southern inspection team was quickly determined.

Three craftsmen and determined mineral surveyors, including Shisan, were each assigned a portable compass that Changsheng had just developed.There is also a complete set of field survey equipment such as engineering shovels.

The map is a new version that has been rewritten and modified. It is an absolute secret and is carried by Tweety, the commander-in-chief of the southward journey.

The medical team is a group of sister nurses led by Xiaoqing. They are not only proficient in various first aid and pharmacological knowledge, but also experts in the prevention and treatment of various poisons and miasma. Of course, if Sun Simiao is not considered too old, Changsheng will also approve him to go of.

The guard team is the elite among the elites, mixed with some of Commander Liao's subordinates, including many able-bodied people from the green group, and even a few older first-year students, among them there is hope to see the round earth The fourth child.

In addition to being responsible for daily guards, they also need to record the local customs and specialty species.

In addition, in addition to Thirteen, the diplomats also have a small butler appointed by the housekeeper who has been dealing with the government for a long time, so that there are also official people, which makes up for Thirteen's shortcomings in this regard.

So when Li Jing got acquainted with Li Shimin and gave him the jade pendant, the team set out to the south with sufficient supplies to follow the movement of the sun.
