Chapter 32 Get out the Arabic numerals!

Ji Cheng wanted to inquire about his brother's situation, but Lantian camp was a military camp and could not be approached at all.

Ji Cheng is just a small one and only has a pavilion chief. How can he easily enter Lantian Camp?

The grandfather and grandson discussed for a long time before finally paying attention.

Ji Chang was an old soldier who attacked Chu, and successively experienced Li Xin's attack on Chu and Wang Jian's attack on Chu.

Due to his outstanding personal ability, Ji Chang served in Wang Jian's central army.

And in the forest, there were many old soldiers who attacked Chu like Ji Chang.

Several of them were also driving for King Che of King Che. Well... Although they were the co-pilot, they were barely considered personal soldiers.

"I used to play in the Chehou Camp. Sheng and Sun, the two of them drove for Chehou. The eldest father went to ask to see if they could meet again..." Ji Chang spoke with a hunched over.

Sheng and Sun, the two are lonely and widowed elderly people in the village.

The offspring died in battle, the daughter-in-law remarried, and she could not have children again. In short, only the elderly were left in the family.

Like them, it was not uncommon in this era. After Qin destroyed the six kingdoms, the war never stopped. He attacked the Xiongnu in the north and the Baiyue in the south.

There is a win or a loss in the middle, and the pace of expansion of the Qin Dynasty was paved with the soldiers and soldiers.

Sheng, grandson, this is the case. The child dies on the battlefield and he is unable to give birth to another child, so the offspring can only be cut off.

However, both of them were meritorious in the attack on Chu, and their titles were not updated until the fourth level, so they could be exempted from labor service. They also had slaves at home, but their lives were not very difficult.

Sheng and Sun, the two of them started to have strange tempers since they died. However, they were both meritorious people, and their titles were not low among the villages. They used to drive for Chehou, but even the villagers were unable to restrain them if they did not break the law.

"Sun was very successful in the past, and he wanted to help him." Ji Chang said.

Ji Si was loved by people since he was a child, and even Ru Sheng. All lonely and widowed people with a weird temper like Sun like Ji Si. Only by having a rare smile on Ji Si, Ji Si felt a feeling of pain from thousands of people as the child he picked up.

I went to visit this family in the countryside since I was a child, and sometimes I was stayed at home by others.

Ji Chang was knocking from door to door in search of Ji Si who was staying in the room.

Ji Chang knew that although he had served under Chehou, he had no idea where this inextricable incense was far away.

Similarly, a noble character like Chehou may not remember the Sheng and Sun who drove for him, but the relationship is always closer than that of himself.

Making up his mind, Ji Chang pulled the gate of the two of them next to each other with a crutch...

After so many years, Ji Chang still feels guilty.

Although Ji Si was a child he picked up, how could he not love him? So why didn’t he treat him as a grandson?

No matter what it was at home, he would just serve him in a bowl of water. It was really difficult for him to be fair in the matter of serving.

...

On the other side, in the Lantian camp, Wang Li asked to see his father Wang Ben, talked about Zhao Si's salt making, and told his eldest father Wang Jian to ask for an urgent report to the First Emperor.

Although Wang Ben was dissatisfied with Wang Li, he did not dare to neglect his father Wang Jian's words. Without any hesitation, he wrote a hurry and selected soldiers to open the news. He set out directly from the road in Lantian Camp and drove straight to the First Emperor.

As for Zhao Si... he squatted and made things happen with a group of craftsmen.

The first one to come up with was the vernier caliper.

Thanks to the reason why the First Emperor unified the weights and measures, now all parts of the country are unified according to the weights and measures of the Qin State, so weights and measures tools like vernier calipers can be used throughout the country.

The length conversion of the Qin Dynasty is also in decimal.

One zhang equals ten zhang.

One foot equals ten inches.

One inch equals ten.

During the Qin Dynasty, one foot was about 23.1 cm.

The smallest unit on the vernier caliper is the segment, which means that the accuracy can reach up to 0.231 cm.

The accuracy of about two millimeters is almost the same as two millimeters, and it is impossible to do it any less, because it is difficult to be accurate downwards based on today's measurement tools.

Because the steel smelting technology was too backward in this era, the first vernier caliper in the Qin Dynasty in Zhao Si was made of bronze.

He skillfully pushed the vernier caliper away, made a piece of wood to hold the measurement, and explained the principles and counting methods to the craftsmen while measuring.

...

As a result, Zhao Si was embarrassed by the mathematical expression of this era again.

It’s not that there is no mathematics in this era.

In fact, there was a multiplication table during the Spring and Autumn Period and the Warring States Period.

And thanks to the fact that some of the Mohist families settled in the Qin Dynasty, the level of the Qin Dynasty military craftsmen was actually quite good.

Especially the military craftsman of Lantian Daying, which is the gateway to Xianyang.

They basically understand some mathematical calculations roughly, and the popularity of multiplication tables is not low. The problem is that the expression and operation of numbers, especially decimals, are too troublesome. When it comes to weights and measures, the conversion to convert and make Zhao Si have a big head.

Zhao Si misses modern Arabic numerals a little. Arabic numerals are indeed easy to use, which is an indisputable fact.

Zhao Si simply chose to put it in a bad way and let the craftsmen study the vernier calipers themselves, while Zhao Si himself planned to make out Arabic numerals and various formulas.

Zhao Si’s math level is not high, which is the math level that he graduated from high school.

Calculus high numbers and other things don't have any at all.

Seriously, after the third year of high school, Zhao Si's math level dropped rapidly, and when he left school and entered society, he had almost forgotten.

In my previous life, I even had to be stunned for a while when I saw primary school students’ questions.

However, in this era of average level of addition, subtraction, multiplication and division, Zhao Si can actually be considered a master of numbers.

"I can't imagine it, I can't imagine it..."

Zhao Si wrote a simplified version of one, two, three, and four on the ground.

"What are you writing?" A voice came from behind. Zhao Si didn't have to turn his head and knew it was Wang Li.

"Numbers, one, two, three, four..." Zhao Si explained.

"Where did this come from one, two, three, four? I saw it overseas?" Wang Li had never seen this one, two, three, four like a ghost painting talisman.

"Okay, I've learned to answer quickly!" Zhao Si smiled.

Because Zhao Si is not so shameless and says that the thing was invented by himself and is too lazy to explain, Zhao Si usually refuses to see it overseas when facing Wang Li's inquiry about the problem.

I asked me how it was? I learned it while traveling around the world.

So much so that Wang Li learned to answer questions as he dealt with too much.

"What are the benefits of this number?" Wang Li sat cross-legged.

The two are already friends and get along more casually, so Wang Li doesn't need to maintain a straight kneeling posture. As long as your legs are not spread open with your legs and the middle door is wide open, it doesn't matter.

Wang Li looked at the ghost painting talisman written by Zhao Si on the ground curiously.

After experiencing salt chubs and other things... Wang Li already knew that Zhao Si would squat on the ground and tidy up like this, and most likely he would have something good.

"It's easy to use!" Zhao Si smiled and looked at the Arabic numerals on the ground.

Making Arabic numerals, fractions, decimals, functions, equations, and various formulas should cause earth-shaking changes to ancient mathematics.

Of course, there is another very critical issue.

This thing...he's easy to learn!
