It's not really a question of the unit of measurement.

But the measurement tools of this era are too rough and the errors are too large.

Of course, the main reason is that in this era, there is no requirement for precision.

It also does not know the elaborate clocks, let alone the delicate instruments such as lathes that require more elaborate lathes.

It's about building a house, making furniture, and so on.

Very fine metering tools are not used at all.

However, the data that Li Su needs to use now must be very fine.

Why was the fixed-point blasting of later generations so precise?

Can the range of blasting be controlled within thirty or fifty meters, or even less?

Because this result can only be achieved after relying on precise data and huge calculations.

Therefore, this time for measurement, Li Yu used a meter ruler purchased from the system.

Well, in Li Su's system warehouse, there are even micrometers and vernier calipers.

It's a pity that no one will use such a delicate tool in this era.

Moreover, the data is not used to this extent.

From that day on, Li Su would take people to carry out a lot of measurement work every day.

Every day, I have to draw a thick pile of drawings.

And after bringing it back, these drawings, these measured figures.

It is also necessary to make an inductive summary, and then go through a large number of rigorous calculations.

Li Su is responsible for summarizing.

Then the calculations and formulas that need to be carried out are distributed to the students in the Zhonghua Academy to complete.

All students are divided into 30 groups of 10 people each.

All data must be cross-calculated and continuously verified to ensure that the formula is used correctly and the resulting data is absolutely correct.

After these figures are summarized, Li Su has to summarize them.

These days, the entire Zhonghua Academy is extremely busy.

In the school palace, from students to teachers-

Well, for the time being, there is only one teacher, Xiu'er.

They all breathed a sigh of relief in their hearts.

Because they all know that the outside world is watching their jokes now!

It is believed that what the King of Shu said, the demolition of the Duobao Pagoda without destroying the surrounding houses is simply an impossible task.

When the time comes, the King of Shu will definitely go to other ways.

However, they did not see how hard His Highness worked!

How much work they have done.

Of course, their job is very simple, just do some data.

They also don't know why these numbers are calculated by these formulas.

What role can the calculated numbers play?

But they firmly believe that since His Highness asked them to do so, then these figures must be useful.

Since His Royal Highness said that in the process of demolishing the Duobao Pagoda, the surrounding houses will not be damaged, it will definitely be done.

……

During this time, the King of Shu was completely on fire.

Even with it, even the Zhonghua Academy was on fire.

Because of the impeachment of the King of Shu by Fan Tongyushi, the debates in the court, the experiments done, etc., all circulated.

During this time, in the entire Chang'an City, it was common to see people doing these two experiments.

Then, they made a miraculous discovery.

It turns out that as long as the water is deep enough, even with just one bamboo pole, the wooden barrel below can be crushed.

It turns out that water pressure is only related to depth.

It turns out that two stones of different sizes fall from the same height, and they will basically fall to the ground at the same time.

Instead of big rocks falling first, they hit the ground later when they were young.

This situation makes some old stubborn very unhappy.

What little stone, don't you understand humility, don't you know how to respect the old and love the young?

The bucket experiment, because it was more restricted, was just that.

But the stone experiment is done almost every day by many people.

Everywhere on the street, you can see people holding two stones, holding them flat on their chests, or holding them high above their heads, and then letting them fall freely.

As a result, I was stunned to find that the two stones really landed at about the same time.

Some people were not convinced, and even climbed on the top of the wall and the roof to do experiments.

As a result, if you accidentally hit others, it will cause disputes in the neighborhood.

Of course, these two experiments have only caused people to marvel.

The truth of the matter, so it is!

After a day or two of amazement, it was thrown away.

Because what the truth is, it doesn't really have much to do with their lives.

How they should live, how they still have to live.

It was another competition that attracted their attention even more.

Which is the competition between the five students of the Zhonghua Academy and the five bookkeepers of the household department.

The final result turned out to be the students of the five Chinese Academy Palaces, and they finally won a big victory.

This incident has completely caused a sensation.

The account office of the household department must be very powerful.

If it's bad, you can't get into the house.

But they were compared to the elementary school students who had only been enrolled for more than half a year!

Gee!

The Chinese Academy Palace is really amazing!

This made the rich and noble families in the entire Chang'an City couldn't help but be moved.

Now the emperor has announced to the world that the number of Shu kings will be promoted throughout the Tang Dynasty.

I heard that the officials of the household department must enter the Zhonghua Academy to study in batches.

Listen, even the household officials have to go in for further study.

The arithmetic of this Chinese Academy is really amazing.

And such a powerful school palace is in Chang'an City, right next to them!

If they send their children in, they will go to school for a few years, won't they have to beat everyone outside the school palace?

At all times, their children can also break the cow!

Isn't it easy to want to be an official or something?

So, for a time, in Chang'an City, there was a rich family.

They went to the school palace to inquire how to send the children in.

Now, the Duobao Pagoda has not been demolished, and the Zhonghua School Palace, as Li Su expected, has become famous.

This is exactly what Li Su wants to see.

For the source of students, Li Su naturally does not refuse to come.

However, it is impossible for these rich children to enter school for free, and they are also provided with pen, ink, paper and inkstone.

These wealthy families, if they want to enroll, it is not impossible.

However, there is an expensive entrance fee to teach.

In addition, you need to take care of your own living expenses and pen, ink, paper and inkstone.

If you want to use the things of the school palace, you can, naturally, but you need to pay a fee.

And for these wealthy families in Chang'an City.

Money is trivial.

They happily paid for the tuition.

And the Zhonghua Academy has also started a new class again.

And this time, there is only one teacher in Xiu'er, which is obviously not enough.

Therefore, Li Su directly selected a few students with excellent learning and strong language skills from among the students at the upper level.

Act as a teacher for new students.

Of course, they also need to learn.

However, it is no longer possible to continue studying with my classmates.

For these few people, Xiu'er will give them a small stove.
