The capital of the country.

Since Dong Dezhang was promoted to the priesthood, he has respected scholars and recruited celebrities, and even Ms. Ma Pengying has been dug back from Beiping Guozijian. Mrs. Ma Pengying and her family returned to live in the capital, where they were conferred a doctorate on the king.

The Ph.D. is mainly to study his own knowledge, supplemented by teaching, and the teaching is mainly responsible for teaching, and the division of labor between the two is different.

Everyone in astronomy, Mrs. Ma Pengying's reputation is naturally famous, and there are not many disciples who worship under her, except for some who have left the country, most of them follow Mrs. Ma Pengying to continue to do research.

The status of the country is high, and the status of the eunuch is also high, and few people are willing to leave unless there is a better place to go.

The astronomical telescope on the observatory, Dai Guowei, a disciple of Mrs. Ma Pengying, has been tracking astronomy for several years, and because of the name of his mentor, he has received a lot of funding, not only to the seven western provinces, but also to Bonidusi, and to the far north of Nuergan.

The discovery of the equator has re-quantified the longitude and latitude of various places is the achievement of the Beiping Guozijian, and the Beijing Guozijian is naturally not far behind.

Intensive communication methods such as technical newspapers, technical departments and scientific conferences, synthesizing the research results of others, Dai Guowei published a paper with the help of his supervisor.

"Looking at the heavens, measuring the sun and the moon, and understanding the avenue of heaven and earth. There is a certain law in the journey of the planets, and this law is the secret of the way of heaven, which cannot be created by man. Yu said that there are three rules of astronomy. This law reveals that the radius of the planet's orbit around the sun, its period, and the swept area are proportional to the hour. This law is followed regardless of the size or distance of the stars. This is the avenue of heaven and earth, and the outline of the sun and the moon. ”

"Since combing this law, I have spied into the mysteries of heaven and earth, and I can predict the movement of the stars. This is my pride, and it should be admired by the whole world. May our compatriots understand the true meaning of this law and appreciate the beauty of heaven and earth. ”

The new generation of young people is not as low-key as the older generation, and in the relaxed atmosphere of the school, the new scholars seem to be more flamboyant.

After Dai Guowei's paper was released, it quickly caused a sensation.

Many scholars expressed their admiration, believing that Zhang San's discovery had brought great contributions to astronomy, while others thought that Dai Guowei was too arrogant and spoke in a more restrained tone.

But as time passed, people could not refute the three laws created by Dai Guowei, according to his invention, people can really predict astronomical trajectories, and this result has finally been paid more and more attention by scholars.

According to the three laws, a large number of scholars have judged this, and through astronomical telescopes, they can see the mountains on the moon very early, and even judge the trajectory in advance, and observe the phenomenon of moons orbiting Jupiter.

Not only does the earth have a moon under your feet, but also the big planets.

It further proves Madame Marpenying's celestial theory, and the other planets revolve around the sun, which has become the mainstream of the academic community, and some people even ask whether the sun also revolves around an unknown existence.

The whole world, whether floating in the universe, is actually in constant motion.

The master-apprentice relationship between Dai Guowei and Ma Pengying is normal, but there are alternatives.

He Hu, a well-known young scholar in the Ming Dynasty, has a very complicated relationship with his mentor, and even hostile, although He Hu often says that he respects his mentor very much and is his guide, but his mentor's greatest achievement was overturned by his disciples, which undoubtedly makes the two masters and apprentices strangers.

In the audience, the lonely He Hu couldn't help but fall into deep thought after listening to the three rules of Dai Guowei's speech.

He had some preliminary ideas: if these three law phenomena can be explained by the gravitational theory proposed by himself, then many unsolvable phenomena will suddenly become clear.

Thinking of this, he couldn't sit still any longer, and returned home as soon as he finished his speech.

In the two-story small building, after He Hu returned home, he said hello to his mother, then went up to the second floor and closed the door of the study.

The seventh sister showed a helpless look.

When I was young, I was worried that my son would not succeed, but I didn't expect my naughty son to suddenly open up, but my son, who was dedicated to pursuing learning, had not yet started a family, and the seventh sister was worried again.

The seventh sister is not a traditional woman, although she has many thoughts in her heart, she did not force her son in the end.

The seventh sister, who has left the Peking Grand Theater, now lives with her son and takes care of her son's diet, and has no other demands, just hoping to see her son get married in her lifetime.

He Hu pushed out a clean blackboard, thought for a while, and built a model in his mind to try to connect the three laws.

After some thinking and deduction, repeatedly writing and altering, I don't know how long it has been, He Hu finally found a perfect explanation.

The gravitational pull of the Moon on the Earth not only causes the Earth's rotation to slow down, but also causes changes in the flow of materials and plate movements in the Earth's interior.

A change in the speed of the Earth's rotation will result in a change in the strength of the magnetic field, which is generated by the metallic elements in the Earth's interior.

These factors influence and restrain each other, forming a complex system.

To better illustrate his point, He Hu tried to cite the relationship between the movement of the moon, the earth, and the tides.

"The gravitational pull of the Moon on the Earth leads to tidal phenomena in the Earth's water columns, which in turn affect the Earth's rotation speed and magnetic field strength."

"This is because the creation of tides leads to the redistribution of material in the Earth's interior, which causes changes in plate movement and changes in the strength of the magnetic field. This interaction and influence makes the whole system more complex and magical. ”

He Hu's paper caused an unprecedented sensation in the academic circle.

Because He Hu's views are so shocking that they overturn the three views that everyone has formed for thousands of years.

It turns out that floods, waves, earthquakes, wind and rain, etc., are all natural science phenomena.

Fortunately, the religion of the Ming Dynasty was not strong enough, but the status of the literati was higher, so although the monks and Taoist priests tried to oppose it and tried to refute He Hu's doctrine, more scholars were impressed by He Hu's talent and imagination.

Even the young scholar Dai Guowei said excitedly: "I always thought that my three laws were unsolvable mysteries, but now it seems that I was wrong. He Hu's theory of gravitational mechanics provides us with a new perspective and allows us to re-understand the mysteries of this world. ”

Scientific methodology has been the consensus of the Ming academic community, and under this criterion, He Hu's doctrine is too perfect, although there are still many deficiencies, but people cannot overturn it.

The mysteries of the whole universe have been opened up before people's eyes.

I see.

It turned out to be so.

He Hu's teacher took the initiative to say, "I'm not as good as my own disciple. The reconciliation of the master-apprentice relationship has become a beautiful conversation.

Since then, He Hu's name has been widely spread in the academic community, from a famous scholar to an academic Taishan, and He Hu was not yet thirty years old at this time.

His theory of gravitational mechanics has been cited and studied by more and more scholars, and has become a frontier field that has attracted much attention, and He Hu himself has continued to explore in this field, hoping to make greater contributions to the understanding and exploration of the natural world.

"The door to science was opened, and from then on it was the world of science."

The headlines on the front page of the technical newspaper gave the monks and Taoist priests a headache, and they didn't even dare to harass He Hu.

Thousands of years of superstition have been completely defeated by science, even if the world still believes in superstition.

Soon, under a new formula, Dai Guowei calculated the date of the comet's return, which was named Comet Tai Guowei, although scholars know that they will not live to that day, but future generations can prove this great discovery.

If that day is confirmed by posterity, the status of science will never be shaken again.

This year is known as the Year of the Great Planetary Discoveries.

A small hole was cut into the sun-facing wall of a dark hut, and a person stood outside the room, and in the sunlight, an upside-down figure appeared on the corresponding wall of the house.

The Book of Ink explains: "The man of light is as bright as he shoots, and the man who is below is also high, and the person who is higher is also down." It means that the light passes through the small hole like an arrow, it is carried out in a straight line, and the human head covers the light from above, and the shadow is at the bottom, and the human foot covers the light from below, and the shadow is at the top, so the reflection is formed.

This was an experiment of the ancients thousands of years ago.

One of the examples given by natural scientist Tao Lian in his speech the year before last has become a well-known story for many people through the spread of newspapers.

"Light has color."

This discovery is more than just a simple optical phenomenon.

Behind it is the basic laws of nature, the mystery of light and shadow. He Hu reached a bottleneck on the road of gravity and quickly shifted his research direction, hoping that through more disciplinary research, they would eventually complement each other.

In recent years, he has become famous for his research results, and He Hu finally chose one of Tao Wei's achievements. So, he began to devote himself to the study of optics, trying to reveal more secrets of light and shadow.

He conducted many experiments with simple equipment to constantly verify and refine his theory.

He found that the shape, size, and position of the reflection of light through the aperture were all related to the relative position between the light source, the aperture, and the receiving plane. Unlike their ancestors, today's scholars are accustomed to studying the laws and mysteries.

With the passage of time, the theory of optics has been studied by more people, and more and more scholars have begun to pay attention to this field, and have carried out in-depth research and discussion on this basis.

He Hu and his colleagues used Mozi's research as the basis to try to deduce theories to explain many natural phenomena in order to promote the development of science and technology.

Although the experiments of the ancients have been proven, He Hu is not satisfied with this.

He is well aware that there are still many unknown areas waiting to be explored in the field of optics, and there are still many directions that can be further explored in the current research results, so he put his theory into practice and tried to develop more advanced optical instruments with craftsmen.

Although the optical instrument he requested was not manufactured, the craftsmen accidentally made a microscope.

The microscope became one of He Hu's inventions, and the academic community was once again shocked by He Hu, and people were discussing He Hu and shocked by the function of the microscope, but He Hu was not satisfied.

And the starting point of all this is the dark hut and the small hole that was chiseled, which came from Mozi.

"Superstitions are true or false."

Like many famous scholars, He Hu couldn't help but shake up because of the bottleneck of experiments in all aspects, like a mouse that could not find a way out, the phenomenon that the ancients could find thousands of years ago, like a circle, not only other scholars returned to the original point, He Hu also deeply felt that he had returned to the dot.

It's like there's a big invisible hand in the sky that is fiddling with tiny human beings.

He Hu invented many theories, but when each theory went deeper, it returned to the original point.

"Zi is silent, and the strange force is confused."

He Hu muttered.

This is another dot, is it that the sages have already discovered it?

"Boom."

"Whoa."

There was a loud bang in the sky, and thunder and lightning fell from the sky and struck the lightning crane of the clock tower, leaving the people of the building intact, leaving only the charred crane.

He Hu looked at the scene from the balcony.

In the Tang Dynasty's book "Burning Hub", it is recorded that during the Han Dynasty, the Bailiang Hall was hit by fire, and a sorcerer suggested that a copper tile in the shape of a fish's tail should be placed on the roof of the layer to prevent the fire caused by thunder and lightning.

The tile decoration at the beginning of the fishtail set on the roof actually doubles as a lightning protection, which can be considered to be the prototype of the modern lightning rod. As early as before, China already had lightning rods, which were generally decorated with dragon heads, and the dragon's mouth had lightning rods.

In his 1688 book "New Things in China" written by the French traveler Cabriobe de Maganlan, it is recorded that at both ends of the roof of China, there is a raised dragon head, and the dragon's mouth spits out a twisted metal tongue, stretching out to the sky, and the root of the tongue is connected to a thin iron wire, which leads to the ground.

This wonderful device is powerful when lightning strikes, and if lightning strikes a house, the current will travel from the dragon's tongue to the ground, preventing the lightning from destroying the building.

"The Law of Conservation of Energy."

This word suddenly came to He Hu's mind.

The law of conservation of energy is the assumption deduced by He Hu in Wang Yugong's Wang Qi Theory, so where is this huge energy transferred?

The world is like a fog.

It looks like you can go anywhere, but there are barriers everywhere.

He Hu tried to walk in different directions one by one, hoping to reach the end, there is nothing in the world that is more attractive than science.

He Hu, who has been well-fed and cared for since he was a child, has experienced many things, and now he is a respected scholar, and the hobbies of ordinary people cannot attract He Hu, he seems to be a devout believer.

Guozijian is like a semi-closed society.

He Hu pursued his learning.

And outside of the Ming Dynasty.

Yoshihiro Ouchi of the Dog Slave Country died, and the situation in the Wa Kingdom became tense.

Skirmishes between the Burmese vassal states and the Siamese vassal states and Sukhote Tusi continued to be warned, the seven western provinces were not peaceful, the Goryeo vassal states had another popular revolt, the vassal states of the Golden Horde rebelled, and the Ottomans and Timur's descendants started a war.

Because of the change of land and return to the flow within the Ming Dynasty, some places have gradually become unstable.

The ideological controversy that had eased for many years began to emerge again.

With the expansion of the Ming Dynasty and the increasingly complex situation, Zhu Gaochi has only one request, and the premise of everything remains stable.

When the grandson returned to Beijing from the north, within a few months the grandson got married, and Zhu Gaochi's eldest daughter also got married.

Zhu Di is sick.

Zhu Di, who came back from Nanyang for the second time, has not been in good health, and after a long period of recuperation, he has survived the winter but has not improved, which has cast a shadow on Zhu Gaochi's heart. (End of chapter)
