Daming Crazy Emperor

Chapter 324 The Strange Man and the Strange Book
In the imperial study room, Taichang carefully flipped through the scrolls in front of him, his eyes filled with splendor.

This "Algorithmic Tradition" is really a wonderful book!

He really didn't expect that there would be such a systematic and comprehensive introduction to mathematics books in this era.

This is really well written.

The book not only explains in detail various mathematical names, mathematical symbols and units of measurement, but also various formulas of algorithms and abacus formulas.

For example, ninety-nine formulas, addition formulas, subtraction formulas, division formulas, business withdrawal formulas, abacus division formulas, etc.

Of course, these formulas were not all compiled by Dawei Cheng. He collected the essence of mathematical formulas of all ages, compiled them systematically and explained them in detail.

It can be said that as long as a person who does not understand mathematics at all can read the first two volumes of this book, he will definitely be able to learn addition, subtraction, multiplication and division, not to mention becoming a master of arithmetic.

The next ten or so volumes of this book are based on the abacus calculation, taking the arithmetic problems that have appeared in the past as examples, and introduce in detail how to use the abacus calculation algorithm to calculate various types of arithmetic questions.

The book also describes the rules of abacus calculation in detail, perfects the formula of abacus calculation, standardizes the usage of abacus, and completes the complete transformation from calculation to abacus calculation.

Moreover, the book also introduces abacus of various uses in detail, and each abacus is accompanied by a picture.

It can be said that this "Algorithmic Tradition" is a cross-age masterpiece in the history of mathematics or arithmetic.

People in Dongying did not take this book as a treasure for bragging rights, they really took it as a treasure and translated it into Dongying language for study, and it evolved into the far-reaching "Hesuan" later.

This point is recorded in detail in "He Suan Xuan Jing".

Unfortunately, in history, the Wanli, Tianqi and Chongzhen dynasties did not pay much attention to this book until the end of the Ming Dynasty. Later, the value of this book was discovered in modern times and became a mathematics textbook.

Even Joseph Needham, a well-known British historian of science in later generations, commented that Cheng Dawei was the greatest mathematician in the Ming Dynasty, and "Algorithm Tongzong" was the originator of integrated computing!
Integrated computing is the core infrastructure of later computer processors.

Of course, Taichang is not clear about these, he is not a mathematician, nor is he a historian of science.

He just flipped through a few volumes and found that "Algorithms" is a rare mathematics tutorial, and mathematics is one of the foundations of various technical subjects.

In addition, the abacus is a rare calculation tool. Before the advent of computers, the abacus was the most advanced calculation tool, and it is definitely worth promoting.

In other words, this set of books is the rarest basic textbook for the Faculty of Arts and Sciences.

OK!

He was worried that there were no teaching materials in this liberal arts college.

Moreover, science is extremely lacking of famous role models at the moment.

Without any role models, how do you make people choose science?

People who choose science do not know what the future holds or what kind of person they will become!
Liberal arts is different.

Throughout the dynasties, there have been many famous ministers, and these are role models for the liberal arts!

Therefore, this Cheng Dawei must be highly praised and vigorously promoted!
He thought about it carefully, and then said loudly: "Zi Ru, take a piece of rice paper to write a plaque on."

When Cao Huachun heard this, he quickly brought a large rice paper that was more than one foot wide and five feet long.

It is common for emperors to give people plaques these days, but it is the first time that the emperor has given plaques to people today.

What will the emperor write?

Who will this plaque be given to?

At this time, even Cao Huachun was a little curious.

Taichang stood up and picked up the largest brush, took a deep breath, then dipped it in ink, and with a flick of the pen, wrote the four characters "mathematical master" on the rice paper.

Then, he changed to a smaller writing brush, signed "Taichang five years, bestowed by Zhu Changluo" on the left corner, and stamped his big seal on it.

Mathematics guru?

Cao Huachun couldn't help being confused when he saw these four words.

What does this math mean?
Who is this master?

Taichang didn't explain. After signing the deposit, he said to Cao Huachun, "Call a few people, and immediately take them to make a plaque."

Hearing this, Cao Huachun hurriedly walked out, recruited four young eunuchs, asked them to carry it carefully, and hurriedly took it to make a plaque.

Immediately afterwards, Taichang said loudly again: "The decree is to posthumously reward Cheng Dawei with a special promotion to Dr. Ronglu."

My God, it's a special entry into the rich family of the first rank!

It turns out that this master of mathematics is Cheng Dawei, the grandfather of the new champion Lang Cheng Jiashuo!
Of course, at this moment, Cheng Jiashuo didn't know that he was already the number one scholar in science.

After he presented "Algorithmic Traditions", he returned to the inn and fell asleep.

Originally, he was worried that his answering method was wrong, and he might anger the examiner, so he couldn't sleep.

Today, the emperor asked him to make a measuring scooter, praised his genius, and asked him to contribute "Algorithm System", which proves that the examiner was not only not angry, but also recommended him to the emperor.

This also shows that his way of answering the questions must be fine, and he is very likely to be named on the gold list.

As soon as his hanging heart is relieved, he will naturally fall asleep.

However, not long after he fell asleep, before he started to dream, the innkeeper knocked on the door again.

This time the guy knocked hard, and shouted loudly: "Mr. Cheng, get up quickly, get up quickly!"

What?
Cheng Jiashuo got up in a daze, walked over to open the door unsteadily, and said helplessly, "Master, why are you shouting so much!"

If he hadn't had a good temper, he would have cursed.

Are you sick? Why don't you let people sleep?

I just fell asleep, and you shouted outside!
Unexpectedly, the shopkeeper still yelled anxiously: "Mr. Cheng, quickly change your clothes and prepare to receive the order! Just now Jin Yiwei has come to the ward, and the father-in-law who delivered the order is on the way, and the little old man is going to prepare now." Xiangan, hurry up!"

Take orders!

When Cheng Jiashuo heard the words, he became sober in an instant.

Accepting the imperial decree these days is no joke.

Generally, the father-in-law or official who announces the decree will send someone to notify in advance before coming. The person who receives the decree needs to prepare the incense table, dress up and wait respectfully.

The fact that a eunuch suddenly popped up to announce the decree was all made up, and receiving the decree was of a ceremonial nature, so it was basically impossible to make any surprise attack.

He couldn't prepare the incense case, so he could only prepare it with the help of the innkeeper, and he had no choice but to straighten his clothes.

He quickly washed his face with cold water, then put on a neat Confucian robe and a Confucian scarf, and stood in front of the bronze mirror to tidy up.

At this time, there was a burst of intensive footsteps downstairs.

Why are there so many people?
He couldn't help stretching his head to look out the window.

My God, the streets are full of people!
what on earth is this kind of happenings?
Could it be that these people came to see the father-in-law in the palace to deliver the decree?

Should not be!

This decree-delivering occasion is quite solemn, ordinary people are not allowed to come near it, why are they coming to see it?
While he was puzzled, there was already a loud singing from downstairs: "Cheng Jiashuo, Xiuning, accepts the order."

Are these people really here to see the decree?
He quickly ran downstairs, lay down in front of the eunuch holding the imperial decree and shouted: "Long live my emperor, long live, long live."

What is the purpose of the emperor?
Cheng Jiashuo was dumbfounded after hearing this.

The emperor actually presented his grandfather Zhengyipin as a doctor Ronglu!
This is simply a great honor.

You must know that this is a first-class special Jin Ronglu doctor, but it is a literary rank, and it is usually only given after the death of an important court official with outstanding merits.

Unexpectedly, this is not over yet.

He had just kowtowed to thank him, and respectfully accepted the imperial decree, when the eunuch who delivered the decree ordered someone to bring in a plaque.

My God, "Mathematics Master"!
Cheng Jiashuo was almost dumbfounded.

The emperor praised him so much, his grandfather is going to become a sage!

Question, why did the emperor praise his grandfather so much?
