Li Chunfeng thought something in his heart, Lu Heng didn't care.

He's actually very simple now.

That's somewhere else, he doesn't care for the time being.

But in this academy he built.

He still hopes that everything will be the same as in the future.

People can talk about sophistication, but in the final analysis, it is still realistic to seek truth from facts.

Especially now that the college is just beginning to take its first steps.

If this head is not opened properly, I will want to reverse the trend in the future.

That's just too hard.

looked at the information about Li Chunfeng in his hand.

Lu Heng continued to ask: "This says that you were in the first year of Zhenguan, that is, you presented a new calendar to the emperor, so you were made an official?" ”

Li Chunfeng can now be regarded as having slowly understood Lu Heng's temperament.

knew that he was a straight gut, so he stopped engaging in those twists and turns.

He shook his head directly and corrected: "Xiaguan is not a new calendar, but only a correction of some errors and omissions in the original "Wuyin Yuan Calendar". ”

Li Chunfeng said here, and saw that Lu Heng was still signaling to continue.

So I can only tell the old story again.

It's not that complicated.

It was originally the calendar adopted by the Tang Dynasty, which was written by a Taoist priest named Fu Renjun as the "Wuyin Yuan Calendar".

As a result, the calendar is generally not wrong.

But there was a big problem with the prediction of two solar eclipses.

So when the imperial court ordered to revise or replace this calendar.

Li Chunfeng, who had been in the army since he was seventeen years old, had been in Li Shimin's Qin Palace's office as a clerk, and he had eighteen suggestions for revision.

After reading it, Li Shimin adopted seven of them.

In the end, Li Chunfeng also relied on this merit and was promoted to the Taishi Mansion by Li Er.

Another point worth mentioning is that it is the same as Fu Renjun, who originally wrote the "Wuyin Yuan Calendar".

Li Chunfeng is also a Taoist priest, when he was nine years old, he went to Jingyun Temple in Nantuo Mountain, and worshiped Zhiyuan Taoist as a teacher, and since then he has more of a Taoist identity.

But this is not surprising, anyway, the current state religion of the Tang Dynasty is Taoism.

Li Er's Daming Palace also has a special Taoist temple, worshipping his Li family's Taoist celebrity Lao Tzu.

Therefore, there are many people who have Taoist identities.

The incident that Li Chunfeng told was nothing serious.

It's just that when Lu Heng heard that the "Wuyin Yuan Calendar" revised by Li Chunfeng was written based on Gaitian Theory.

The whole person is completely unbearable.

So, he interrupted Li Chunfeng and asked him:

"So you can change this calendar because you also think that the sky above this head is a lid, over our heads?"

Faced with Lu Heng's question, Li Chunfeng nodded very naturally,

"Because of his family education, Xia Guan is very interested in the astronomical calendar."

"So after reading many classics, I still think that Gaitian is the most in line with reality."

In fact, what is the relationship between heaven and earth?

Before the Tang Dynasty, there were many kinds of doctrines.

Among them, there are three more well-known.

They are Gaitian Theory, Hun Tian Theory and Xuanye Theory.

Among them, the theory of covering the sky is very easy to understand, that is, the sky is a cover, and the earth is a chessboard.

The heavens cover the earth, and the sun, moon and stars move above the heavens.

As for the Hun Tian theory, it is believed that the relationship between heaven and earth is like an egg.

The earth is the yolk of the egg, and the sky is the shell of the egg.

The sun, moon and stars are attached to the eggshell.

In both cases, the "heaven" is basically regarded as an entity.

Think of it as real, and those suns, moons, and stars are attached to the sky.

The armillary theory is somewhat different, although it does not explicitly put forward the concept of a universe in later generations.

But it is also believed that 'the sun, moon and stars naturally float in the void, and they must be angry when they do it.' ’

This is actually very close to the real appearance of the universe.

It's just that the ancients still believed that these sun, moon and stars needed the support of 'qi' in order to float.

These three doctrines were born in the Yin Shang period.

After the people of all dynasties and dynasties went to study and discuss.

Now there are three more mature theories.

The calendars used by dynasties and dynasties were basically based on these three doctrines.

It's just that Xuanye said that although it is closer to the truth of the universe.

But because it's too hard to use.

Therefore, all along, the first two doctrines have been more prosperous.

And Li Chunfeng is obviously at this stage of his life, and he still supports Gaitian's theory.

After hearing his words, Lu Heng was already a little speechless.

Now that I think about it, these people can actually start from the doctrine that the foundation is wrong.

Extrapolate a calendar that can still be used.

I have to say that it is really powerful.

However, at the moment, although Lu Heng did not have time to change his mind with experiments for the time being.

But he still secretly crossed out Li Chunfeng from the post of astronomy teacher in his heart.

This is not just Li Chunfeng alone.

But in Lu Heng's view, the entire astronomy has temporarily lost the need to start classes.

Otherwise, unless he himself goes and becomes a teacher for all the students.

Otherwise, no matter who comes to him, there is no difference between what he can teach and Li Chunfeng.

Astronomy vetoed, so the calendar naturally doesn't need to be said.

After excluding these two disciplines that seem to be Li Chunfeng's best skills.

Lu Heng looked at it, and there was only one mathematics to choose.

Regarding Li Chunfeng's mathematical level, Lu Heng did not doubt it.

Anyway, mathematics will have to go through his training before it can be hired.

It doesn't make much difference who comes to it.

It's just that people like Li Chunfeng have a foundation because they have a foundation.

Lu Heng estimated that after he taught them Arabic numerals and those mathematical symbols commonly used in later generations.

They should be able to quickly integrate with what they have learned.

Even Li Chunfeng, who has been famous for more than a thousand years.

has already disappointed Lu Heng on the premise.

Those interviewers in the back, naturally no one can make Lu Heng excited for a moment.

Instead, after interviewing the medical officers who were transferred from the Tai Hospital.

Sun Simiao seems to be quite satisfied.

It seems that these doctors who can be imperial doctors still have some skills.

It's just the same as the other teachers.

How good are they at teaching?

You won't know until you've tried it.

After interviewing these teachers sent by Li Er.

Lu Heng went out again to see the enrollment situation.

However, there are so many students who come to sign up.

Continue to register one by one.

Lu Heng estimates that not to mention today, it is estimated that he will not be able to recruit in another three or five days.

And now it is still the spring ploughing season, and it is unrealistic for so many parents to wait here with their children.

So Lu Heng simply waved his hand and ordered a team of people from the camp in the western suburbs.

Let them mount their horses and follow the line that is waiting in line to sign up, notifying them as they bang the gong.

Registration is now cancelled, as long as it is a student who is willing to come to the academy for classes.

There is no age limit for men and women, and when the time comes, just go directly to the several manors prepared by Lu Heng to take classes.
