My Daming New Empire

The "Mo Jing" in the Spring and Autumn Period and the Warring States Period actually summarized mechanics and optics. The principle of leverage was analyzed in detail in the book, and a series of applied tools such as scales and wheelbarrows were born.

Moreover, in the Mojing, it also expounds the principles of light and shadow, small hole imaging, concave lens, and convex lens. Unfortunately, such knowledge can only be hidden in the library of the palace, and no one is willing to learn it.

Because learning these things will not help improve a person's living environment, and will be suppressed.

In addition to mechanics and optics, the ancient Chinese also did a lot of research on other subjects, such as acoustics.

The art of "Zhuangzi" records the resonance phenomenon that occurs when tuning a zither. This fundamental and overtone resonance phenomenon was discovered much earlier than in the West. It was not until the [-]th century in Europe that Da Vinci performed the first resonance experiment.

Mo Di once set up an urn in the ground, using the phenomenon of resonance to detect the enemy's strategy of digging holes to attack the city.In the Song Dynasty, Zeng Gongliang called this method "Weng Ting" in his "Wu Jing Zong Yao", which is the application of acoustic effects in military affairs.

Needless to say about magnetism, the invention of the compass has fully explained the achievements of the ancient Chinese in magnetic research.

Then there is thermology, another neglected subject.

As early as the Spring and Autumn Period, "Kao Gong Ji" judged the degree of hotness and coldness of objects according to their colors during the process of smelting metals.And formed a long-standing steel smelting process.

In "Lunheng", it records the state changes of heat balance, heat conduction and cold and heat cycle.

The Kongming lanterns in the Three Kingdoms period are an application of heat.

As for electricity, although this subject is only available in later generations, in fact, the records of this subject have appeared since the emergence of human civilization history.

In ancient times, when thunder and lightning struck, trees were ignited, and people knew about thunder and lightning.

"Hanshu" records tip discharge, lightning protection knowledge and related devices.

The "Natural History" of the Western Han Dynasty recorded that rubbing tortoiseshell can charge the tortoiseshell and absorb small particles.

"Lunheng" records the use of magnets to generate electricity by friction.

In the Tang Dynasty, the book "Xuan Zhen Zi" had already carried out a scientific analysis of the connection and separation between thunder and electricity.

But all of these are only scattered applications, and there are few tools and theoretical explanations that can be applied from ancient times to modern times like scales.

This is not only because the ancients only paid attention to application and not to theory, but the key is that they lack the soil for the development of other disciplines.

Zhu Zhanji himself has no time and no interest in studying these.So when he met Madi, who was less than 15 years old, he gave all these books to Madi, and asked him, a big kid who was interested in physics, to study them.

And Ma Di did not live up to Zhu Zhanji's expectations, and quickly summarized and summarized the application of physics in the ancient books according to Zhu Zhanji's classification.

This is the book he gave Zhu Zhanji three years ago.

In addition to these, he conducted a detailed analysis of Zhu Zhanji's hang glider, and added a subject of fluid mechanics.

Another three years have passed, and Maddie is almost 20 years old.

Due to Zhu Zhanji's order, the Ma family did not propose marriage to Ma Di, and he himself had no idea of ​​getting married, so he was buried in the research room of Xiamaqiao Farm all day long.

The book he gave to Zhu Zhanji three years ago was just someone else's, but now, he has experimented with most of the content in the book and added a lot of content.Formed a collection of theory, experimental basis, principle analysis of the physics series.

Although he is young, he is the lecturer of Zhu Zhanji's Habayashi School of Guardianship. In recent years, his students have many noble children and children of civil servants.

Even if everyone disapproved of the physics he taught at first, they couldn't ignore the influence of the hang glider.

All of Da Ming's hang gliders were produced under his leadership, and the hang glider has become an important reconnaissance unit in the Ming army.

Not only the students of Habayashi Wei School, but even the armies of all sides sent people with professional military training to Xia Maqiao to learn hang gliding, which made the young Ma Di receive the attention of the entire court.

No matter how honorable the children of honor, the children of civil servants thought they were noble, they would not dare to ignore this future uncle, so this made Ma Di's reputation even higher.

Zhu Zhanji originally considered marrying his eldest sister, Princess Jiaxing, to Ma Di. Jiaxing was born in the seventh year of Yongle, eight years younger than Ma Di.

Ma Di comes from a wealthy family, and he has a gentle personality, even a bit petty. Jiaxing should be a good destination for him to marry.

But even if calculated according to the imaginary age, Jiaxing is only 12 years old this year, and he will have to wait two or three years to get married.

But this time when he returned to Daming, he raised this matter with Mrs. Zhang, but Mrs. Zhang objected.

It's not because the Zhang family doesn't like Ma Di, but because Zhu Zhanji himself has married Ma Di's younger sister, and then married the princess, and there is a saying of changing marriages.

Although changing relatives is very common among common people, it is precisely because of this that even landlords and gentry are taboo about changing relatives, let alone the royal family.

So now that Zhu Zhanji saw Ma Di, he felt a little guilty, and wanted to help him find a good marriage.

With Ma Di's conditions, it might not have been in Xungui's eyes.But Zhu Zhanji married his sister and became the throne in the future. The Ma family had at least one earl.

Although he is the second son in the family, he is highly valued by Zhu Zhanji, and now he is famous among nobles and civil servants.

And he doesn't have to join the army, he has a gentle personality, he looks good, and his family is rich.

So he didn't have to worry about not being able to find a wife, and even the first-class honorable families wanted to marry him.

After inspecting the Gewu Research Institute, Zhu Zhanji specially told Ma Di: "This book "Basics of Gewu" has been completed and will be used as the basic textbook of Habayashi Hygiene in the future. But you can't always limit yourself to this position. The Ming Dynasty needs you in the future." There are more places, and you should also put your energy into continuing to deepen your research. Therefore, your task now is to select a few proud disciples from Habayashi School, teach them the things in the book, and then step down as a lecturer."

Ma Di was a little anxious, and said with a long bow: "Your Highness, I am willing to teach, not to mention that now I am only allowed to teach for half an hour a day, even if I prepare lessons, I don't need half an hour, one hour a day is enough, there is no delay Weichen research."

Zhu Zhanji said with a smile: "Based on your current achievements, I have wronged you by making you a lecturer. After a few more months, I will establish my first university in Ming Dynasty, and I will promote you to be a professor at that time."

"University? Not Taixue? I'm not even a Juren, so I can be a professor?"

"I said you can, you can." Zhu Zhanji didn't want to explain the difference of university to him now, patted him on the shoulder and said: "Xiner is now seven months pregnant, and I'm afraid she will give birth in March It's been three years since we went out, and you also asked your mother to visit the palace more often, so you don't need to care about other people's words."

"Yes!"

Let Li Liang put away Ma Di's new "Gewu Foundation", and several people moved to the small yard next to the Gewu Research Institute.

The Electric Power Research Institute is said to be the department with the highest expectations of Zhu Zhanji but the slowest development. This is mainly due to two aspects.

One aspect is that the study of electricity requires the foundation of various theories. If you don’t even know what electricity is, you want to use electricity, which is a bit too big a step.

Secondly, in terms of applied research, Zhu Zhanji himself only knows what it is but does not know why.

For example, he is very clear about the role of motors. Industrial development requires electricity, and the conversion of electrical energy into kinetic energy is the most important thing.

But Zhu Zhanji only knew that the motor was wrapped with copper wires, but he didn't know the working principle.

On the most widely used electric lamp, Zhu Zhanji knew that the light bulb was first made of bamboo charcoal, and then lead wire.

He also told the researchers the function of the light bulb, but until now, the light bulb has not been produced yet.

Zhu Zhanji himself does not know how to use bamboo charcoal as a filament, so how can he teach others?

As for using tungsten wire as a filament, it is even more difficult, because the melting point of tungsten is more than 3000 degrees, and the current level of smelting cannot reach that step.

Therefore, the current Electric Power Research Institute is still a toy of the royal family. It is sent out to perform during the Lantern Festival on the 15th of the first lunar month every year.

The motivation of these people is not small, the magnets are getting bigger and bigger, and the coils are getting bigger and bigger. The power generation device made of huge magnets and coils can easily electrocute people to death.
