[Qing] If you don't work hard, you will be forced to inherit the throne

The course belonging to the second brother of the prince started again after a month!

The last time the prince took them to play with magnets in class is still fresh in my memory, and the little brothers are very much looking forward to the new "science course".

Sure enough, Yinreng took them to play new tricks this time. He brought a prism made by Liuli official kiln.

Yinti missed the last time. He was studying in the army. Naturally, he would not come back to his study as "free" as Yinfeng. He only felt that he had missed a lot. This time he took a one-month vacation for the Chinese New Year. Go back to the study to have a look.

Cao Zhen, as the companion of His Highness the Crown Prince, studied with the third elder brother in the upper study for a month, thinking that he was tearful, maybe because he knew too much and had good knowledge, the third elder brother always regarded him as the prince His Highness's "stand-in" couldn't find His Highness to answer his questions, so he came to him to answer his questions, so that in order to solve the endless tricky problems of the third elder brother, Cao Zhen had no time to spare, so he put out the hard work that he had studied with His Highness in the past Follow up the studies in the study room.

This time Yinfeng came, not only with the help of his little assistant Cao Zhen, but also with an older brother who came to listen.

"The knowledge I want to teach you today is related to light. Books about light include "Mengxi Bitan" in the Northern Song Dynasty and "Gexiang Xinshu" in the Yuan Dynasty. In "Mengxi Bitan", it is called "Hong It is the shadow of the sun in the rain, and the sun shines in the rain (1)', so today I will use a prism to present a 'rainbow' to everyone."

What a magical thing it is for a small prism to turn out the colors of the rainbow under the sun!

"The manufacture of the prism was learned by Gu, not created by Gu, but after reading a book, he found that there was a scholar named Newton on the other side of the ocean who had created it before he was born. Invented a prism, and discovered seven colors of light, red, orange, yellow, green, blue, blue, and purple, but count them, how many colors does this rainbow have?"

It is not easy to carefully distinguish the color of the scattered light, especially it is difficult for the human eye to distinguish between blue and purple, so that the counting of the little brothers is different from what Yinfeng said.

The younger elder brothers have no guts, so they are embarrassed to speak up to refute Yinreng. Yinzhi is the most courageous, knowing that he must question when he is studying with the second brother of the prince. The second brother likes him to raise questions, whether it is right or wrong, as long as he raises it, Always being appreciated and encouraged, this also made Yinzhi full of confidence and exploration in learning since he was a child. As long as he is not afraid of learning and has no subconscious inferiority complex, his grades will come naturally, and he will slowly build himself This is Yinzhi who, under the influence of Yinfeng, loves learning more and more, is naturally sensitive to literature, and is really talented.

Since both the crown prince and the eldest elder brother went to the previous court, someone taught them privately. In the upper study room, Yin Zhi had the best grades and was also the oldest. He looked like a big brother.

"Second brother of the prince, it seems that there are not seven colors, there are only six colors in total."

"Indeed there are six kinds, because our eyes can only see six of them." Yinfeng nodded and said, "Only by relying on sophisticated instruments, can we let everyone see the two colors mixed together, blue and purple. But This is not what Newton recorded in his book. He wrote that 'six is ​​an unknown spell, and it is the devil who is tempting the world. How merciful is God, how can the light have six colors?' So he attributed it to For Seven Colors."

Yinfeng said with a smile: "In fact, there were many missionaries who believed in God in the Qing Dynasty. They came from another part of the ocean on a big ship. They are different from the locals here in the Qing Dynasty. Some of them have yellow hair. Blue eyes, isn’t it weird? They think six is ​​an ominous number, just like we have avoided the number four since ancient times, because it sounds like death.”

Yin Zuo opened his mouth wide, showing an expression of surprise.

Missionary, what a strange vocabulary, what are the sea and the big ship like?

The prince's class always makes them imagine, the wings of imagination fly into the air like birds, and they wish to grow up and explore this unknown and attractive world.

From the scattering of light, the refraction of light, and then talking about the appearance of small holes, he took his younger brothers to play with convex and concave lenses. Yinfeng also asked someone to bring them a distorting mirror, and asked his younger brothers to illuminate themselves around the distorting mirror with three sides Playing, you can make a few little ones smile, and hover in front of the mirror to take pictures.

Yinti is 14 years old. According to Han Ama's intention, he will be looking for Fujin candidates for him at the beginning of the draft next year. The crown princess will also start looking for him. The concubine Hui in the harem has begun to "crash", and he himself has not yet awakened. That string stayed in the army full of big men, and when he came back, he heard that he was about to start looking for Fujin, so he was in a daze!

Once he gets married and establishes a career, he will be an "adult prince", and the meaning will be different. At that time, he can display his ambitions and do many things that young princes cannot do.

He would be the first adult son Khan Ama sent out, whether leading the army in battle or otherwise.

Just like what Lu Dehong said, his own family is of course more trusted by the emperor than outsiders, and the Jueluo clan must hold great power in the army and have a place in the court.

Little did he know that his own son was more trusted by Khan Ama than his clan.

Perhaps feeling the threat from Yinti's status, Le Dehong replaced Yinti's cronies who had infiltrated the army with his own people on the grounds that he would cooperate with the emperor and His Royal Highness to carry out military reforms.

If the clan thinks too highly of itself and is not sensible enough, then even Khan Ama can't bear it sometimes. I don't know if Baocheng knows how much trouble his proposed military reform has brought him?Did he know that Khan Ama had begun to investigate the Noble Women of the Eight Banners to find him a candidate for the crown princess?

Yinti, who already had career troubles, was in a daze, and the little buddies here laughed and laughed.

"Hahaha, the sixth brother suddenly turned into a short winter melon."

"Wow, Fifth Brother has become thin like a bamboo pole!"

Yinzhen's heart: Hmph, these are just brought by the prince to amuse the children, so I won't be fooled.

"Fourth brother, come and take a picture, it's fun," Yinzhi pulled Yinzhen, and pulled him to the mirror.

I don't know what the fourth brother is doing awkwardly, he follows behind reservedly, really pulls him to the mirror, and can't stop staring at himself in the mirror.

Yinrong asked with a smile, "How about it, isn't it fun?"

Yinzhen looked calm: Am I such an ignorant person?What a concave-convex mirror is has long been known.

The rest of the little elder brothers: "It's fun——"

"Okay, let's talk about our current astronomical phenomena, everyone, go back to your seats."

Yinfeng clapped his hands, and gave an order, and the little elder brothers didn't resist at all, they sat back in their seats obediently and waited for him to continue teaching.

Especially Yinzuo, Yinzhen's younger brother, looked at the prince eagerly, as if there was an invisible tail wagging behind him.

Yinzhen was heartbroken for a while, his expression of being on the sidelines before changed, and he began to listen carefully, why the prince can always coax the little ones to be obedient and obedient, what exactly does he use to make them admire and love him, These are all worthy of his deep study.

[Big friend, the fourth younger brother is stealing lessons secretly, he must be envious of you being liked by the younger brothers. 】Yin Reng is happy: If the fourth brother doesn't always have a cold face and smiles kindly and warmly every time he sees his brothers, he won't be so disgusted by Xiao Liu.

It's a pity that Yinzhen, who was reborn with memories, couldn't get rid of his integrity and lower limit, and couldn't get along with children like a real child because he was too much influenced by his previous life.

He is a grandfather who is over 60 years old in his two lifetimes. He really doesn't have the heart to guess what the children are thinking. As an emperor who is used to being pampered, since he succeeded to the throne, only others have always guessed his thoughts. Without him To guess other people's minds.

He is used to being hit by the prince every time since he was reborn in this life. He just hopes that the prince doesn't keep thinking about it. His old bones really can't stand the toss, and his heart is not ordinary tired.

Yinzhen even had some resentment: It would be nice if the prince was reborn with memories, but if he had memories of his previous life, he wouldn't be so noisy.

Although the prince Yinreng in his previous life was lonely and arrogant, he had his own burden as a prince, so he would not do things that would damage his noble image as a prince.The current Prince Yinfeng is basically a king of children, and Lianhan Ama is hard to resist him.

"Next, what I want to talk about is the waxing and waning of the moon. The fact that the moon itself does not shine has already been explained in the Song Dynasty!"

"Shen Kuo wrote in "Mengxi Bi Tan" that 'the shape of the sun and the moon is like a pill, how can we know it. The profit and loss of the month can be verified...'(2)"

Yinfeng knows that theoretical courses are always boring, but while explaining, he took out the round night pearl as a demonstration of the sun, and asked people to pull down the curtains to create a dark environment for the room. It's getting interesting again.

After the lecture was finished, Yinti originally planned to meet with Yinrong in private, talk about the information he had obtained recently, and mention that his recent endless actions had exhausted the courtiers and Khan Ama, and he even beat him up. I was caught off guard.

Yinfeng wanted to have a good communication with the fourth brother first, but brother Tutu's kindness was hard to resist, and the third brother also looked at him with Bambi's eyes, and he couldn't bear to refuse.

However, since Khan Ama let him go and promised him to come to the study to develop relationships with his younger brothers, how could he miss such a good opportunity?If he doesn't do something meaningful, Khan Ama doesn't even know how hard he is working!

So when the little elder brothers went to the literature class with the gentlemen, he called the three brothers to the place where Dolittle was repairing books in the upper study room. There were a lot of documents hidden in it, and people often came to clean it, but the grand master was gone. However, this place was completely empty, and instead became a place for Yinrong to rest.

Yinreng cleared his throat, called everyone to sit down around the small table, handed paper and pens to the brothers, and started his new plan - pulling the brothers to write the year-end summary together.

This year younger brothers write year-end summaries, and next year ministers write year-end summaries. In the year after next, the whole Qing Dynasty is writing year-end summaries. Criticism and self-criticism are a good habit. Yinfeng said to Xiaomei in his heart: I feel lonely You can spread this good habit, ah no, pass it on to others, so that everyone can be proactive while remembering the bitterness and thinking about the sweetness, strive to break through themselves, and welcome a better future!

[Big friend is right!Criticism and self-criticism are fine traditions and fine styles, which are worth advocating! 】Yinfeng thought so, and did so.

"It's the end of the year again, what have the brothers done and learned in the past year, why don't you come to a summary meeting, learn from the mistakes of the past, look forward to the future, and hope that next year will be better. I feel that the year-end summary is helpful for us to look back on the past year and make plans for the new year. The new year has a new atmosphere. As we grow up, the world is also changing. We can't stand still and wait, we can only look forward. Only by making sufficient preparations can we face up to difficulties and solve various difficulties that will arise in the future.”

Yinti said with emotion: "What Baocheng said is very true. In the past year, you and my brothers got together less and separated more. I thought I would learn something and gain something from the Ministry of War, but in the end I was too timid to go. To start, so that many good opportunities were missed. Compared with you who studied in the Ministry of Rites and the Ministry of Officials, you are still a bit behind."

Yinfeng started his speech. He looked lonely and said in a low voice, "It's a pity that I have not achieved anything in the past year."

Yinzhi: "Huh?"

Yinxuan: "..."

Yinzhi hesitated to speak: "Why did the second brother of the prince say that? Your contribution to the government has been passed down to the upper study room, and the younger brothers are all envious of you!"

Yinfeng sighed: "People are always envious of the brilliance of others, but they don't know that they are also being envied by others. When I was young, I always hoped to grow up quickly and explore the outside world. Now that I have grown up, but I miss the carefree childhood. If someone asks Gu what he wants to do when he grows up, Gu will probably answer 'When I grow up, I want to be a child'."

Yin Mo: You can pull it down!

The author has something to say: "Mengxi Bi Tan" is an encyclopedia rich in content, which greatly summarizes the scientific achievements of ancient my country, including many discussions on optics.There are straight line propagation of light, lens, mirror imaging and so on.

Note (1) on the dispersion of light. "To the extreme north of the black water border at the foot of Mount Yong'an. It's rainy and foggy. I saw the rainbow in the stream in front of the tent. I watched it with my colleagues, and both ends of the rainbow were in the stream. It makes people cross the stream, and they face each other across the rainbow. The distance between them is several zhang, and the middle is like a sale. If you look from the west to the east, you can see it, and it will cover the evening rainbow. If you look east and west in the standing stream, you will see the sun's gravel, and you can't see anything."

Note (2) Demonstration about the phases of the moon: "The shape of the sun and the moon is like a pill. How can we know it? It can be verified by the moon's profit and loss. The moon has no light at all, it is like a silver pill, and the sun shines like a light ear. The birth of light, the sun is in its Nearby, so the light is sideways and you can see it like a hook. As you get farther away, the light shines obliquely and the light is slightly full. Like a bullet, half of it is coated with powder. If you look at it from the side, the powder is like a hook; You can know that it is like a pill."
