Time is really amazing sometimes, and more than ten years can change a lot.

There are already a lot of newcomers watching worry-free live broadcasts.

These people haven't watched the live broadcast since they were born, but they just listened to their parents and grandparents talk about it, and said that today's good life is brought by the fairy who broadcast the live broadcast.

They can't imagine what the live broadcast will be like, and they have been looking forward to seeing it.

Now, their wish has come true.

Looking at the fairy on the canopy that was obviously thrillingly beautiful, but it was easy not to pay too much attention to her appearance, these people miraculously calmed down after being excited.

They were listening very carefully to what the fairy had to say.

Qin and Han dynasties

The First Emperor looked at the peach that appeared on the canopy with red eyes.

His face was full of desire.

The same was true of Emperor Wu of the Han Dynasty.

Two heavy immortal cultivators plus immortal obsessives really couldn't resist the attraction of the peach.

They immediately tipped, and at the same time sent a barrage.

"Ask the fairy to give me a peach."

Worry-free sighed when he saw it: "No, the peach is too rebellious for you, if it is given to you, it will really hurt you." ”

After thinking about it, Wu Wu added another sentence: "The fairy spirit in the peach is too strong, and ordinary people will die violently if they eat it." ”

The First Emperor and Emperor Wu of the Han Dynasty felt very disappointed at the same time, especially disappointed, but helpless.

Even if they are in power and control the life and death of countless people, they have no way to do anything about life and death.

In addition, there are some people who want to be peachy when they hear this, and they also dispel the idea of asking for a peach with no worries.

"Alright, let's move on to Mozi."

Worry-free smiled: "Mozi's name is Zhai, a native of the Song State during the Warring States Period in the late Spring and Autumn Period, he lived between about 372 BC and 289 BC, and was a descendant of the Song State Doctor Muyi. ”

"Mozi once studied Confucianism, but after studying it for a while, he didn't like it very much, and created his own Mohist school to compete with it."

Mozi put forward the views of love, non-attack, Shangxian, Shangtong, Tianzhi, Ming ghost, non-life, non-music, and festival funeral, with love as the core, and Shangxian and thrift as the fulcrum. It made the Mohist a prominent scholar in the Qin and Autumn Warring States periods, and in the era of a hundred schools of thought, it was known as non-Confucianism and ink. ”

Wuwu talked about some things about Mozi, and after finishing speaking, he looked through the information again.

"The following two we have talked about before, one is the Zhang Cang who was saved by his ass, and the other is Zhang Heng of the Eastern Han Dynasty."

"About Zhang Heng, he once made an armillary sphere and a geodynamic instrument, but unfortunately, the geokinetic instrument was lost, and the imitation of the descendants did not have the function recorded in the history books, so that many years later, many people doubted that Zhang Heng did not create a geokinetic instrument at all......"

As soon as the words of worry-free came out, many people began to curse.

Especially the era in which Zhang Heng lived.

At that time, everyone really felt that the geodynamic instrument was an object that was against the sky, and when I heard that someone denied Zhang Heng's geokinetic instrument, where could it be relied on, I don't know how many people scolded various dialects in their mouths.

Wu Wu waited for a while before saying: "Zu Chongzhi, a mathematician and scientist during the Northern and Southern Dynasties, for the first time, actuarially calculated pi to the seventh decimal place, and the ancestral rate he proposed has made a significant contribution to the study of mathematics. ”

During the period of the Northern and Southern Dynasties, Zu Chong, who was calculating something, raised his head violently.

He rubbed his ears and listened to what the fairy had to say again, making sure that it was him.

Belch?

It seems that later generations still recognize him very much, and he has also left a name in history.

For this reason, Zu Chongzhi is still very happy.

Zu Yuxing hurriedly ran in: "Father, father, the fairy is talking about you, you have left a name in history." ”

Zu Chongzhi looked at his son and handed over a page with a calm face: "Calculate this." ”

Zu Xuan looked at the densely written numbers on the page, and the excitement on his face immediately disappeared, and his face was full of frustration in an instant.

"Father."

The worry-free voice was still ringing in his ears, but Zu Xuan had to accept his fate to take the piece of paper and make calculations.

"Zu Chongzhi was not only proficient in mathematics, he was also proficient in astronomical calendars, mechanical engineering, music, and was also a literary scholar, and he formulated the Ming Calendar, which reformed the calendar......"

"In honor of this great scientist, in 1967, the International Union of Astronomers named a crater on the moon Zu Chong no Crater."

"On November 9, 1964, the Purple Mountain Observatory named the asteroid discovered in 1964 with the international permanent number 1888 as Zuchong Star."

At this time, Zu Chongzhi could no longer maintain a calm posture.

His son Zu Xuan was even more irrepressible excited, and he had already thrown the piece of paper aside and happily circled around the room.

"Father, listen, craters, asteroids, heavenly ...... You are in the sky, in the moon, in the ......"

"In 1986, 30,000 commemorative silver coins of Zu Chongzhi with a face value of five yuan were also issued."

"Pudong New Area of SH City also named a road Zuchong Road."

"In addition, there is also a Zuchong Garden in SH City, and there is also a Zuchong Middle School in HEB Province."

Under the canopy

I don't know how many people envy their eyes to the point of redness.

Listen, listen, not only the mountains on the moon, the stars in the sky, but also on the earth, and silver coins, and schools, and roads, and gardens......

Who is this ancestor Chongzhi, and how can future generations respect him so much?

During the period of the Northern and Southern Dynasties, there was already an order from those in power to immediately go to find Zu Chongzhi, and when he found it, he must be treated respectfully, and he must not have any disrespectful behavior towards Mr.

Speaking of this, she stretched out her hand, and a plate of fruit was automatically placed in front of her.

She picked up the ripe fruit and took a bite, and the plump juice immediately flowed into her mouth.

Under the canopy of the sky, many people who were greedy fell with their saliva.

Many, many people, especially those who are interested in science, originally wanted to force themselves to read literature and study the Four Books and Five Classics in order to gain fame.

But at this moment they changed their minds.

They don't want to do what they don't like to do.

They want to do something down-to-earth.

Just like Zhang Heng and Zu Chongzhi doing academics, they may be able to leave a name in history, even if they can't be remembered by future generations, but they are worthy of their hearts in this life.

After eating the fruit, he continued: "Li Daoyuan is also a person in the Northern and Southern Dynasties, he is a very famous geographer in ancient China, he wrote forty volumes of water classics, and has a great influence on the development of China's hydrology. ”

Immediately afterwards, Wu Wu told some of Li Daoyuan's deeds.

Many began to memorize and write down the stories of these people so that they could tell them to their descendants.

"There was also a scientist during the Northern and Southern Dynasties, he was Jia Sixian, and he wrote the book Qi Min Yaoshu, which is the earliest and most complete large-scale agricultural encyclopedia in China."
