Live broadcast: Ancient people accompany me to make up lessons

I can barely understand the first three questions, but for the following questions, I really feel like I don’t even know the words.

What about Avogadro's constant, batteries, atomic numbers, compounds...

What is this, anchor!

Even if there are a few geniuses, after understanding the meaning of Arabic numerals and symbols yesterday, they can follow the calculation steps in their minds, and then learn the anchor's problem-solving ideas and compare them with their own. But today, because the knowledge system is too complicated The system did not post any explanations. In half an hour, the anchor could finish writing 13 multiple-choice questions.

Seeing her put down her pen, everyone under the sky cheered up.

Here it is, it’s time to compete with luck again. There are really a lot of things I want to ask the host today.

[Reminded by the system's countdown, Xiaoxiao, who hesitated about the last question, could only choose an answer based on his intuition and start the lottery.

Okay, one hour is up, it’s time to draw our lucky audience, everyone! 】

1. Qin: Gongshu Zhi

2. Qin: Mo Ting

3.Chinese: Zhang Heng

4.Chinese: Liu Chan

5. Tang Dynasty: Sun Simiao

6. Tang Dynasty: Wang Xiaotong

7. Tang: Zhou Sheng

8. Song Dynasty: Wang Zhuo

9. Ming Dynasty: Zhu Houzhao

10. Ming: Ma Yilong

Gongshu Zhi, not many people knew this name in later generations, they just thought it was a lucky guy, but in Daqin, when they saw this guy's last name, many people knew which family he belonged to. Looking at Mo Ting below him, they all A knowing smile.

Just as they thought, when these two families saw this name, they really cared about it. Li Si, who was the first to be listed on the list before their Qin Dynasty, although people from different schools were very unhappy with this guy's luck, he was still a prime minister after all.

Mo Weishang, who was later listed on the list, was heard to be from the Mo family. Of course, the other schools that did not have anyone on the list were unhappy. Oh, there are still people from the Yin and Yang family.

In short, seeing the Mo family on the list makes other schools feel uncomfortable, let alone other schools. If nothing else, if your name is on the list, it is luck and strength. The luck of being certified by the sky and known to everyone in the world is also of great use.

Apart from Confucianism, Mohism’s other enemy, the losers, was one of the jealous and resentful families.

But it's okay now. Someone from the Mo family is here, and there are also people from their public losers. Who will lose to whom?

Lucky spectator No. 1 was full of joy. He quickly thanked the curtain and asked questions amidst the congratulations of the uncles around him.

"Excuse me, host, what is this chemistry?"

This is not to show off deliberately, but they are really curious about what chemistry is. Currently, the information that can be extracted from watching the anchor writing papers is that this subject is very mysterious and is suspected to be related to changes in things.

["Chemistry..." Xiaoxiao took a sip of the still cold soy milk and thought about how to explain it.

"A type of natural science. Together with mathematics, physics, biology, geography, astronomy and other disciplines, it is one of the six basic natural sciences."]

Crazy Recorder: Okay, here comes a new question, what are other disciplines about, and what is natural science?

Li Si, who was also copying quickly by himself: The education of later generations is much more comprehensive and complete than he thought. It is not only the 12 years of studying from elementary school to high school, but also these basic natural subjects. On this basis , there will definitely be other more different things.

[“The world is composed of matter. Chemistry mainly studies the composition, properties, structure and change laws of matter at the molecular and atomic levels, and creates new matter.

Generally speaking, chemistry is a discipline that studies the properties and changes of the microscopic world, and uses this as a basis to explain some phenomena of the macroscopic world.

It is closely related to our lives. The most basic ones, such as iron-making, basically use physics and chemistry knowledge. 】

Those who listened carefully exclaimed: "Studying the laws of matter in the world. Creating new matter, isn't this called creation!"

There are many people who think so. Even the rotten scholars who study the books of saints and sages will not think that this is useless learning when they hear about creating new substances.

Especially when they heard about iron smelting, everyone's eyes jumped.

Is it possible to talk about iron-making knowledge casually? Aren't you just a senior high school student? Didn't you even teach such state secrets in a school?

"iron?"

In the Qin and Han dynasties, which had not yet widely used iron tools, the emperors were excited when they heard these two words.

Intuition told them that the anchor should know a lot about iron-making, otherwise he would not use iron-making as an example so easily. They really want to know, but they don't want everyone to hear this knowledge at all.

Can I have a class alone, host?

[But physical reactions are completely different from chemical reactions. A piece of pure iron has been refined from a solid (iron ore) into a liquid by a high temperature of more than 1,500 degrees Celsius. Its properties have not changed. The main element iron has not changed. It is just a physical reaction; but this iron is oxidized. , it becomes rusty, which is a chemical reaction between iron and oxygen. ”]

Some people have guessed that oxidation may only cause things to turn yellow or rot after being stored for a long time: So as long as oxidation is prevented or avoided, can things be prevented from rotting and rusting?

Also, how did you measure the high temperature of more than 1,000 degrees? The hottest temperature there in a day is 40 degrees. How do humans know that the temperature is so many times higher than the temperature?

[“Speaking of which, the most ancient chemists should be alchemists and alchemists, but they are all in the wrong direction.

If an alchemist wants gold, he must refine it with gold. Otherwise, how can substances be exchanged, especially since the chemical properties of gold are so stable? As for the alchemist... I can only say that he is good with heavy metals, so be careful not to get poisoned by heavy metal poisoning. . ”]

Ying Zheng, who was five years away from his death and had taken the elixir made by the alchemist, but still could not get the elixir of immortality from the Immortal Island: heavy metal poisoning! ?

As soon as Tianmu finished speaking, all the officials in the court looked at him. Li Si was the first to speak: "Your Majesty, would you like Doctor Xia to come for a consultation?"

"Father, I will send someone to find Dr. Xia right now!" Fusu spoke hurriedly for the second time, his face changed, and the normally well-behaved eldest son just put down his pen and went out to look for him.

Ying Zheng looked at Meng Yi with a livid expression on his face: "Let's take care of those alchemists first."

If there is anything, wait until Xia Wuqi sees it before talking about it. Although he is angry at being fooled by the alchemists, he listens to everything Tianmu said.

The oldest chemist, right? He wanted to see if he really had this ability.

When Tian Mu said this, the expressions of other alchemists in the palace changed. Some were afraid that they would be killed by Emperor Qin and implicated their family members, and did not understand how their elixir could be poisonous. Some wanted to run away immediately when they sensed something was wrong, but Meng Yi quickly led people to surround the place, and he had a guilty conscience. If you want to run away, just drag him down and take him away.

Not mentioning the Qin Dynasty here, other alchemists of later generations were indignant and felt that Tianmu was talking nonsense. They had already tried their best to neutralize the erysipelas in the alchemy with various materials, so how could there be any "heavy metal poisoning"? !

He has been the emperor for nine years and is only twenty-four years old. He has not yet made elixirs by himself. Jiajing asked: If you don’t use metal to make elixirs, it will be fine. If you learn this chemistry well, can you make elixirs by yourself by changing the mood of everything in the world? ah.

He knew that by following the anchor, he could learn the way to become an immortal!

The iron smelting industry was more developed than in previous dynasties, and more people were seeking immortality than before in the Tang Dynasty:...

Li Shimin wrote it himself, hoping that someone could ask something very useful. Putting aside heavy metal poisoning and so on, can you talk about alchemy? The Tang Dynasty is really short of gold.

But the anchor stopped talking and called a second person.

Mo Ting and his fellow apprentices in Xianyang City looked at each other and saw encouragement in each other's eyes.

Nothing can be compared to those who are public losers!

"May I ask the host, what do those unintelligible characters mean?"

["Character, this is the "Periodic Table of Elements". Let me read it to you..."

He dug out a chemistry book from the stack of books next to him, showed them the table with the corresponding Chinese version, and read it in Chinese and English.

"The world is made up of substances, and the basic substances are the list of chemical elements summarized by the Russian chemist Mendeleev."]

Just like the previous subjects, except for a few who are interested or smart, others have already started to have a headache looking at this dense table.

Everyone before the Ming Dynasty looked at some fonts with doubts: hydrogen, chlorine, nitrogen, lithium, cadmium, beryllium... Are there such words?

The clans of Zhu Houzhao and Zhu Houcong: Ah, isn’t this our name?

[Xiao Xiao finished reading and smiled: "According to the Essentials of the Taiqing Alchemy Sutra, Sun Simiao, the king of medicine in our country, was the first to discover and create elemental arsenic. You wouldn't even know if you didn't check that the famous medical scientist was still making elixirs." Where is the teacher?

However, long-term exposure to arsenic is harmful to the body. It is used in pesticides, herbicides, and insecticides. Its compound ditrioxide is the famous arsenic. ”]

He never expected that he would be called the King of Medicine in later generations, and that his achievements in alchemy would be so recognized. Sun Simiao was also surprised.

He didn't go out to collect medicine today, and the free clinic was arranged in the afternoon. He also picked up paper and pen in the morning to prepare for studying. He didn't expect to gain such a big harvest.

Arsenic...arsenic...he seemed to vaguely know what it was talking about.

People who were originally curious about what it was changed their colors when they heard the arsenic behind them. They thought that if the alchemy produced was all arsenic, no wonder the anchor said that the elixirs were all heavy metals.

["Sorry, I'm going too far." Xiaoxiao continued to talk about the periodic table of elements. “It is the 118 elements on this table that make up the entire world we can perceive.

Elements are composed of smaller atoms. After Dalton's atomic theory was proposed in the early 19th century, people had a clearer concept of chemical elements. By 1869, 63 elements had been discovered.

The atomic-molecular theory of matter was finally recognized and completely established. It ended the long-term confusion on the issues of chemical formula, atomic weight, and valence. It not only became the basis of the entire chemical theory, but also became the basic belief of the entire natural sciences. 】

"Atoms and molecules of matter...how did they discover, confirm, and measure them?" People who were thinking hard were still confused and didn't understand what was going on.

[Mendeleev arranged the 63 elements known at the time in the form of a table according to their relative atomic weights, and placed elements with similar chemical properties in the same column to create the prototype of the periodic table of elements.

When creating the periodic table of elements, he not only sorted the first 62 elements, but more importantly, he made amazing predictions about three unknown elements.

Mendeleev reserved vacancies for "unknown elements" in his periodic table. In the following years, 11 unknown elements such as boron-like, aluminum-like, and silicon-like elements predicted by Mendeleev were successively discovered. In particular, the subsequent discovery of helium, neon, argon, krypton, xenon and radon added new noble gases to the periodic table of elements.

In 1875, the French chemist Bois Beaudeland discovered a new element while analyzing sphalerite in the Pyrenees Mountains. He named it gallium and published the main properties he measured about it.

Soon he received a letter from Mendeleev, in which Mendeleev pointed out that the specific gravity of gallium should not be 4.7, but 5.9-6.0.

At that time, Bois-Foudeland was very puzzled. He was the only person who had the metal gallium in his hands. How did Mendeleev know its specific gravity? After re-measurement, the specific gravity of gallium was indeed 5.9. This result surprised him greatly.

After carefully reading Mendeleev's periodic law paper, he said with emotion: I have nothing more to say. Facts have proved the great significance of Mendeleev's theory.

Single-handedly, Mendeleev improved Russian science, which was still weak, and became their national hero. ”]

National hero, these four words that sound glorious and glorious when heard, are the respect foreign countries have for this Mendeleev.

After hearing the above story, who can not say that he is a genius, and who would not be angry at being called that because he won honor for his country?

Sun Simiao, a master of alchemy, watched the periodic changes of elements. His men quickly recorded the changes, but his mind was thinking that Mendeleev was indeed a genius and was curious about how he calculated it.

Originally, I wanted to ask the anchor some medical knowledge, but since the anchor doesn’t study medicine, I decided not to force him. Instead, I asked him how this element and atom was discovered and measured.

If you can understand the mysteries of this subject, will you know how to refine everything in the world?

The ancient alchemists who were fond of alchemy and the Taoist priests who followed them took the time to write down the words on the table, and had great enthusiasm for the subject of "composing all things in the world".

Both Zhu Houzhao and Zhu Houcong are busy writing. Although their purposes are different, their enthusiasm for this subject is real.

Study, must study hard!

Yinreng, who was flipping through medical books in Xian'an Palace and letting his daughters copy knowledge in front of the sky (his sons were all studying in the study), was thinking about this knowledge and seemed to understand something in a flash.

For this chemistry, the anchor only mentioned Sun Simiao, but the previous knowledge about today's periodic changes of elements, the Western numbers on the screen, and the previous knowledge were not available to many Central Plains people.
