West of the city, the royal family's mansion.

The laboratory has been established, mainly including balance scales, alcohol lamps, dynamometers, pulley sets, vernier calipers and other equipment.

These things were all made by Wang Yuan with ideas and then found craftsmen, and he now has twelve craftsmen in his house. Wang Yuan regularly gave the yamen a sum of silver every year, in exchange for the craftsmen at home not to have to serve as a servant, so that the craftsmen could stay here with peace of mind.

It's a pity that Yan Shenzhen still couldn't research pure and transparent glass, which made many of Wang Yuan's experimental equipment unable to be made.

At noon, it's time for a break.

Hong Laifu, the director of the laboratory, brought people back with a batch of materials. When he saw Zhou Chong in the courtyard, he immediately came over with a smile and reported: "Steward Zhou, there is not much silver in the laboratory, and the master asked me to pay twenty taels from you." ”

"Running out again?" Zhou Chong was surprised.

Hong Laifu said: "There are many places to spend money, and Manager Zhou can check the accounts at any time." ”

Zhou Chong nodded and said, "Then you will go to the treasury tomorrow morning to withdraw it." ”

"Thank you, Steward Zhou!" Hong Laifu clenched his fists and said.

The laboratory was renovated from a large hall with a wooden partition painted with fireproof paint, divided into several separate areas.

At this moment, Wang Wensu is working in the household department, and Du Jin and Bao Chaozhen are studying mathematical problems.

Zhong An, the laboratory assistant, and six children, Hong Gui, Lu Yu, Lu Sheng, Lu Xiang, Fang Xiaoyan and Li Erya, are all serious about their homework. Although he is a student of Wang Yuan, Wang Yuan no longer has to teach in person, Du Jin and Bao Chaozhen can teach everything.

"Senior Brother Du, my question is done." Zhong An handed over the homework book.

Du Jin quickly browsed it, pointed to an application problem and said, "I miscalculated here, take it back and review it well!" ”

Zhong An hurriedly took back the homework book and lay there thinking about it. This guy was born with fine skin and tender meat, and he has been a scholar since he was a child, and he has learned the four books very well, and he can go to the Xiucai exam, but he is completely blind in the Five Classics, because the young master's teacher is unwilling to provide in-depth tutoring.

Now, in the entire laboratory, Zhong An is the hardest learner, and his math level has reached the third grade of primary school!

Another laboratory assistant, Li Wan, was completely useless in her mind on the right path.

She is mainly responsible for serving tea and pouring water, helping to organize experimental equipment, although she is usually studying, but when she sees those numbers, she has a headache.

Seeing the housekeeper Zhou Chong coming to the courtyard, Li Wan immediately ran out, and the two sneaked to the garden.

Zhou Chong is not yet twenty years old, and Li Wan is almost forty years old, and these two guys actually sparked. Of course, for the time being, they haven't hooked up and become adulterous, but they often sing together. Zhou Chong used to mix in the opera troupe, and Li Wan used to be a Qing Qi person, and they had a lot of common topics in opera.

"After a few years of learning from the old Ming scriptures, I was ranked high in one fell swoop. The two dynasties divided the iron coupons, and the jade pot leaned on the ice for thousands of feet...... Madame, I bought a golden carp at night......"

"Xianggong is right, let's take Wang An to find a boat and leave tomorrow morning."

"Those who release fish are all said to be good, and those who shoot tigers are called Zhou Chuqiang. If you go to another country, you can't bear to buy live fish, and now you are full of grace and beasts......"

The two sang the miscellaneous version of "Journey to the West", but they didn't dare to sing too loudly, so they only pressed their voices to convey their feelings there.

Suddenly, Wang Yuan walked out behind the flowers and said with a smile: "Sing well, what kind of play is this?" ”

Zhou Chong and Li Wan were so frightened that they were scattered, although they really didn't have any personal feelings, they still had the illusion of being caught and raped by their masters.

"II...... Second brother," Zhou Chong hurriedly explained, "Assistant Li and I are just learning opera, and we both sing during the break, so we haven't delayed our business." ”

Li Wan was even more frightened and knelt on the ground, only kowtowing, not daring to speak.

Wang Yuan smiled and said, "I can understand. ”

Zhou Chong didn't like to read, he had nothing to say to those people in the laboratory, and he couldn't get along with the other servants in the house on an equal footing. Li Wan's situation is similar, after a long time, she panicked, and when she met Zhou Chong, who also knew how to sing, she naturally began to learn opera.

Zhou Chong said: "Second brother, I'm afraid of disturbing others in the laboratory, so I come to the garden every time to sing, not a private meeting. ”

"Get up," Wang Yuan said, "one of you is unmarried, the other is unmarried, although there is a slight difference in age, but there is no violation of the moral law, I have no leisure to mind your affairs." I just happened to take a walk in the garden and heard someone singing. ”

Li Wan bowed her head and said, "Old ...... Sir, I promise not to sing with Steward Zhou anymore. ”

Wang Yuan smiled: "You haven't said yet, what kind of song you sang just now." ”

Zhou Chong felt a little relieved and replied: "The miscellaneous drama "Journey to the West" was taught to me by Assistant Li, but there is no one in Yunnan. ”

"There will be "Journey to the West" this year?" Wang Yuan was quite surprised.

Li Wan replied: "The miscellaneous drama of the slave family was handed down by the Yuan Yu of the previous dynasty. ”

Wang Yuan nodded and said, "I see." ”

In fact, until the early years of the Qing Dynasty, it was not known who the author of "Journey to the West" was, and many people speculated that the author was Qiu Chuji.

Ji Xiaolan denied this statement, just because many yamen and official names in it belonged to the Ming Dynasty. When he arrived in the Republic of China, Lu Xun appointed Wu Chengen as the author of "Journey to the West", because there are relevant records in "Huai'an Mansion Chronicles".

However, the compiler of "Huai'an Mansion Chronicles" was a friend of Wu Chengen. Later, the local chronicles were edited twice, and this record was deleted, which has caused endless debate in the academic circles.

Some people even say that the author is Yang Shen, because there are many anagrams in "Journey to the West", and the answer to the puzzle is Yang Shen and Sheng'an (Yang Shen). This statement is rather nonsense, and the Huai'an dialect is widely used in the book, which does not conform to the language habits of Yang Shen, a native of Sichuan.

Wang Yuan chatted casually, and Li Wan bowed down and retired, leaving only Zhou Chong to deal with it.

Wang Yuan admonished: "If you really have any interest in her, I will allow the two of you to get married, but it must be a wife." If you are only greedy for temporary fun, it is best to keep your distance, Li Wan is also a hard worker. ”

Zhou Zheng suddenly had an impulse to ask Wang Yuan to marry Li Wan. But thinking about the age gap between the two, and because of Li Wan's past, Zhou Chong could only end this first love and said, "Second brother, I will pay attention." ”

Wang Yuan paced all the way to the laboratory, and found that Gu Yingxiang was absent from work again, so he didn't stay in the Jinyi Wei Yamen, and came to study mathematics with Du Jin and Bao Chaozhen.

"Ruoxu, look at this experimental data, is there a better way to calculate it?" Gu Yingxiang beckoned to Wang Yuan.

These people are all studying physics, and today they also conducted an experiment to fix the wooden frame with a spring suspension, and then an iron ball fell freely, hit the bottom of the box and moved in the countryside with the box. Among them, the maximum distance of the box drop needs to be measured for follow-up experiments.

Bao Chaozhen and Gu Yingxiang wrote a long list of equations respectively, but the answers they calculated were different.

Wang Yuan smiled: "This problem is very easy to solve, a few days ago I researched a new mathematical method, tentatively named 'calculus'. Let's assume that the ball falls to the bottom of the box and the ball moves with the box at a speed (total)'......"

Ancient China already had the idea of calculus, but it was just a similar thought, which was equivalent to standing in front of the door of calculus, but it was always so close to the door.

Wang Yuan told calculus in detail, and Gu Yingxiang, Bao Chaozhen and Du Jin instantly understood, and then they were amazed.

Zhong An stood by and listened carefully, he didn't understand a word, he only felt inexplicable, and he made up his mind to work harder in the future.

Suddenly, a servant came in and announced: "Master, Yang Xiu of the Hanlin Academy is here to visit!" ”

What does Yang Shen do?

"Invite him to the parlor." Wang Yuan said.

Since the imperial examination, Wang Yuan and Yang Shen have not had much in common.

Wang Yuan was busy fighting wars and engaging in mathematics, physics and chemistry, and he was surrounded by soldiers and mathematics enthusiasts. Yang Shen watched politics in the imperial house, and usually recited poems against the members of the Lize Society, surrounded by politicians and literati.

Although they are both officials of the Hanlin Academy, they don't even see each other much.

Wang Yuan received with a smile: "Brother Repair, please take a seat!" ”

"Thank you!" Yang Shen hugged his fist.

Wang Yuan asked directly: "With Brother Xiu coming, I don't know what you have to do?" ”

Yang Shen was also very direct, and said: "A few days ago, I went to the observatory to observe the stars, and I saw a mirror of the gods, and I knew that the surface of the moon was uneven. I consulted the Yin and Yang officials and learned that they had discovered that the sun was the center of heaven and earth, and I was shocked for a while. Looking at Jun's masterpieces "Mathematics", "Geometry" and "Physics", these three books are from shallow to deep, and the mystery is incomparable, so that I can't sleep at night! ”

Wang Yuan was surprised: "Brother Yong is also interested in this kind of trail? ”

"Poetry is also a small way, how is it different from arithmetic?" Yang Shen said.

"That's right." Wang Yuan said.

Yang Shen hugged his fists and said: "Jun's masterpiece, although I have studied it hard, there are still some unclear points. Therefore, I took the liberty to visit and wanted to ask for advice in person. ”

Wang Yuan laughed: "Haha, let's go to the laboratory." ”

Yang Shenzhen is not a nerd who only knows how to dance and write, not only astronomy, geography and mathematics, but also medical skills. This guy's book is the Book of Changes, and he can memorize the full text after only twenty days of study, leaving a lot of time for in-depth study, and arithmetic is the basis for truly mastering the Book of Changes.

Coming to the laboratory, Yang Shen was very curious about everything here. Touching here and asking there, I actually mixed up with a few math enthusiasts.

Putting aside Yang Shen's political stance, this guy is really charming, and whoever communicates with him is like a spring breeze.

Yang Shen's curiosity and thirst for knowledge are strong, he sees new things as if he understands, and when he encounters something he doesn't understand, he wants to delve into it. He also went to listen to Wang Yangming's lectures, but felt that Wang Yangming's theory of mind was too biased, Zhu Xi's science was also very rigid, and Yang Shen had his own set of understanding of the Four Books and Five Classics.

Moreover, as a disciple of Li Dongyang, with Yang Shen's current reputation, he belongs to the well-deserved heir of the leader of the Chaling faction.

The Chaling faction has monopolized the right to speak in the Chinese literary world, and Yang Shen can do things in a proper manner. When Li Dongyang died, he would be able to "order" the people of the world, but Yang Shen didn't want to take over the Chaling faction. It's just that Yang Shen's literary concept is not the same way as the Chaling School, and he also looks down on his teacher's literary works.

Compared with Yang Tinghe, Yang Shen is more assertive and pursuing, and at this time there is still a pure heart that has not been extinguished.

This thing even went to study storytelling, and only after eating everything thoroughly did it turn to other aspects. Now that he is obsessed with "new astronomy" and physics, he will not give up halfway until he has fully mastered Wang Yuan's knowledge.

For half a month, Yang Shen came to the laboratory every day, except for eating and sleeping, he spent all his off-duty time at Wang's house, and this state ended until he was sick.

A genius who can memorize the full text of the Book of Changes in twenty days, and has a mathematical foundation himself, has made rapid progress in studying wholeheartedly. In less than a month, Yang Shen was able to use calculus to calculate parabolic experiments in the field of physics.

Does he want to be a scientist?
