Liao Zhen was admitted to Jingshi University with the same academic ability in the 20th year of Chongzhen. After completing his university studies, he had no tutor to accept him as his apprentice, so he was assigned to the artillery factory in the 22nd year of Chongzhen.

In any aspect, Liao Zhen has nothing outstanding. Unlike those energetic young people, he was already forty-two years old when he entered college - although he and Liao Xing were of the same generation as Liao Xing. Because he was old and calm, he could not act cute and begged to take in like a young man in front of the professor.

Liao Zhen was once a "faithful son" in his family.

In the Liao family, a family that started with business, Liao Zhen's father was a accountant, and he also learned arithmetic with the accountant since he was a child. Therefore, he became interested in mathematics - so much so that he was indifferent to anything else.

Such people are destined to be eliminated in the original historical time and space, and at best they become a well-known accountant. However, in the Ming Dynasty, mathematics is valued by the crown prince as a basic subject, and all students of Jingshi University must learn mathematics. This is also the benefit of the clan. People can make the best use of it. If such a "numbers" can study at Jingshi University, there will be another way in the family.

But no one expected that Liao Zhen was basically in a self-study state during his two years in Zhengshi University. Today's mathematics is still in the process of sorting out ancient mathematical achievements, such as the art of cutting circles, Tianyuan art, and Dayan's art of seeking one. Liao Zhen has already learned it with great skill. As for the Taixi mathematics translated by Xu Guangqi and others, it is not as deeper than that of Qin Jiushao, Liu Hui, Zu Chongzhi and others, and it can only be regarded as a broadening of horizons.

What Liao Zhen loves the most is the entire room of mathematics books in the library, which is also the place where he spent the longest time.

Surprisingly, he never participated in the Steam Engine Program from the time he was admitted to the time he left.

The steam engine program mobilized Jingshi University and Huangming Naval University. Hundreds of teachers and students, accounting for almost one-third of the total number, but he was still not selected as a mathematical nerd. Until he was assigned to the gun factory, he found a steam engine operation model in the gun factory warehouse - which was provided to the gun factory to study how to use the steam engine for the gun casting work.

"This thing is very heavy. It consumes a lot of energy and has little effort, and it's just a joke."

This is what many people in the artillery factory think of steam engines, and at most they use it to lift heavy objects.

Liao Zhen really intervened in the manufacturing of the steam engine, but it was Wang Yongshun who came to the artillery factory to seek technical support.

It is undeniable that the artillery factory is the place where the most cutting-edge craftsmen in the Ming Dynasty were gathered. Although they lacked scientific research capabilities, their craftsmanship was well-deservedly the top of the Ming Dynasty.

Liao Zhen’s job is to help Wang Yongshun improve boring and carpentry. It makes the “circle” dug out of boring and carpentry more “circular” and more satisfying the design data.

After Zu Chongzhi used Liu Hui's round-cutting technique to push pi to the seventh position after the decimal point, the mathematical significance of pi is far greater than that of practical significance. Because no craftsman needs to be so accurate when making tools. Liao Zhen, a nude silly, intends to do this job to the extreme.

The units of weight and measure in the Ming Dynasty were already different from those in later generations. The degree also refers to length, and the commonly used are zhang, size and inch. These three units are enough to meet the living needs of ordinary people. For longer units, there are 10 zhang as the guide, or directly use "li" as the unit.

Below the inch, there are five units: Hu, seconds, hair, and liter. This is from the "Sunzi Jing": "The silk sprouted by silkworms is Hu, ten seconds is one second, ten seconds is one milli, ten milli is one milli, and ten milli is one cent." In the Song Dynasty, "second" was changed to "silk". Therefore, in the Ming Dynasty, it was incub, minute, six, hair, and silk, and these ten abdicated units were Hu.

The length of the Ming Dynasty's construction scale was 32 cm in the metric system of later generations, and the inch was 3.2 cm, divided into 0.32 cm... and so on, when it comes to this unit, it is enough to measure infrared wavelengths, cell sizes, and bacterial sizes. Of course, these are not used today.

Liao Zhen improved the work accuracy to 10% which was almost crazy among the current craftsmen of the Ming Dynasty.

However, once the finished product is made, the effect is also very significant.

The cylinders produced after the process is improved easily reach the best level before.

Liao Zhen was therefore absorbed into the "Steam Engine Project", and Wang Zheng also wrote a letter to the Crown Prince in person, hoping to transfer Liao Zhen from the artillery factory back to Jingshi University to teach. Because what he did was not to create a height-precision tool. He also invented differential through the circular cutting technique.

In the eyes of Ming people such as Wang Zheng, they just thought this problem-solving idea was very interesting and opened up an unknown place. However, Zhu Cilang was very clear about the impact of calculus and analytical geometry on world civilization.

Before Descartes established the analytical geometry system and Breniz and Newton each invented calculus, Eastern and Western mathematics was basically in a state of equality, and in some fields, Chinese mathematics was even better. However, after the invention of analytical geometry and calculus, Chinese mathematics remained in the static world, while Western mathematics entered the dynamic field and began the journey of describing the world with mathematics.

"The Methodology of Correct Thinking and Discovering Scientific Truths" published by Descartes in the tenth year of Chongzhen and in 1637 of the Yeli calendar, now has nearly a thousand Chinese translations, renamed "Methodology". His analytical geometric ideas can also be found in the library of Jingshi University.

Liao Zhen’s attainments in terms of things are not outstanding. Perhaps in his opinion, the problems solved by others are not problems, so he is more concerned about the problems of "infinite small" and "limits". This is the fire of thought that was born from calculus, and China has long accumulated enough firewood.

When the "fire" and "fire" meet, there is another relaxed environment, so a new subject designated by the Crown Prince was born: "calculus".

With such achievements, the improved manufacturing process of steam engines is simply "adding the head", and the name "Liao Zhen" will inevitably be recorded in history because of calculus.

For such a mathematician, Zhu Cilang certainly did not hesitate to worship him with the highest reward.

In October of the 220th year of Chongzhen, the Ministry of Rites awarded Liao Zhen a doctorate. Before that, Jingshi University had hired him as a professor and set up a separate college of mathematics, with him as the dean. On October 15th, Emperor Chongzhen gave him a banquet and an iron coupon, and appointed Liao Zhen as the third-class uncle, avoiding the death of two people.

The only official titles of the Ming Dynasty were Duke, Marquis and Bosan. Zinan never used them after the founding of the country, until Zhu Cixuan opened up as a civil title. The titles Liao Zhen obtained this time were already a serious title.

Wang Zheng did not expect Liao Zhen to be treated like this. He looked back at Liao Zhen's achievements and realized that he was indeed old and foolish and had forgotten his original intention. Back then, he was able to go further and further on the path of Western learning because of his math skills.

"Always keep your original intention, you will have more than enough to become a Buddha." Wang Zheng, a Catholic, actually spoke a Zen proverb and said somewhat lonely: "I'm walking too far!"

Zhu Ciying originally wanted to regulate calculus to a certain extent to avoid making wedding dresses for others, which stimulated the geniuses of the countries of Tessie. Although Newton and Breniz are still young, scientific elites such as Huygens, Descartes, and Pascal should be able to understand the power of it.

And it must be admitted that the academic environment in Europe is better today than that in the Ming Dynasty.

"Forget it, even if it was spread to Europe, it will be two or three years later. It's just a moment of this competition." Zhu Ciyang said: "And why can't European talents be used by me?"

Human success comes from ninety-nine percent efforts and one-percent genius, which is the one-percent genius that can create the spark of human civilization. Now, 53 years old, Descartes serves as the tutor of Queen Christina in Sweden, only a few months before his limit.

Like Song Yingxing, Christian Huygens, who thought of using black gunpowder to make internal combustion engines, was only twenty years old. He studied law and mathematics at Orange College where his father was the principal, and had shown his child-prodigy talent.

The twenty-six-year-old Bryce Pascal was first published by Crown Prince Zhu Cilang a few years ago. He is now looking down at Paris on the top of Clermont-Ferrand, repeatedly conducting experiments on atmospheric pressure. And it should be that just three years ago, he and Fermat, the "king of amateur mathematicians" completed the foundation work of modern probability theory.

Thinking of these names that I rarely heard of after college, Zhu Cilang suddenly thought of Li Shimin's famous saying: "All heroes in the world are in my hands."

It seems that in addition to the Kwai Xin Award, a larger "skin" is needed to embrace these stars in the history of science.

Therefore, on the eve of the winter solstice of the 22nd year of Chongzhen, the Ming Mathematics Award, named Liao Zhen, was established. The winner of the first world was naturally Huiyuan Bo Liao Zhen. At the same time, he also won the award, René Descartes, who was far away in Northern Europe, also won this award for his achievements in analytical geometry.

The envoy who gave the award was Prince Jing. Because he volunteered to go to the distant Northern Europe, he finally received the award from the Seifeng. After the award was announced, the newly-invaded King Zhu Hezhi of Jing had to set off with a three-pound gold medal monument and five thousand taels of silver, hoping to arrive in Sweden before Descartes' death.

"The New Year Festival can only be celebrated on the road." Zhu Hezhi complained in a low voice, but did not dare to let anyone hear it. He didn't know that he was actually picked up by his title of prince. Because Descartes died in February 1650, no matter how he traveled, he would never see the living Descartes.

If Zhu Cixuan remembered this, the new prince would probably not even have the chance to complain.

In any case, this thirty-man delegation boarded a sea boat from Tianjin and drove south under the push of the sea breeze. Considering the wind direction and ocean currents, King Jing might be able to catch up with the King of Tang's fleet.

Just when Zhu Cilang was happy for another great victory in the Ming Dynasty in the scientific battle, Liao Zhen opened a company, built a steam engine privately, and transformed it into gravel, contracting the construction of the 1,500-mile official road in Zhejiang Province... Finally, it was submitted to the Crown Prince's desk by the East Factory.
