"This is Nanhai No. 1...... Shipwreck. ”

At this moment, the Ganlu Hall and the Chengdu Mansion were all looking at the light curtain with a daze.

The picture shows a mottled shipwreck, with a huge hull, half-capsized and sunk to the bottom of the sea.

The hull looked tattered, with some white stone-like things clinging to the hull, and unknown aquatic plants wrapped around the hull, gently swaying with the waves.

Sunlight shines down through the water, dyeing some of the colors of the blue waves, creating a well-composed picture.

This is a picture that neither Li Shimin nor Kong Ming and Liu Bei can imagine.

Zhang Fei whispered to Lai Lai:

"In this future life, you can not only go to the heavens but also enter the sea, and this world is so big that you can go everywhere?"

At this moment, Zhang Fei suddenly envied the "Xuande" who was sent to the next generation.

He also wants to go to the afterlife to experience the heavens and water, and experience the high-speed rail that has been tangled for a long time.

And maybe I can go and give my eldest brother a stick of incense......

Liu Bei didn't notice Zhang Fei's messy thoughts, and after quietly admiring the wreck, he said a little strangely:

"What are those two dots next to them?"

Pang Tong and Kong Ming identified each other, and said with unusual affirmation:

"It's human!"

As the light curtain slowly advanced, Liu Bei also saw that it was indeed a person, wearing a completely unknown equipment, and it seemed that they were communicating with each other by gestures in the water.

"They're ...... Gaozu is on top! ”

Liu Bei couldn't help but shout, what did he see?

A black box was like a giant beast in the Classic of Mountains and Seas, and it opened its mouth and swallowed the wreck in one gulp.

Li Shimin of Ganlu Hall seemed to understand: "This is to fish up the wreck?" ”

No one cared about his words, Fang Du and the others watched several divers hurriedly gesticulating to each other at the bottom of the box, and finally seemed to confirm each other, and the mouth of the closed giant beast slowly rose.

The light curtain slowly floated upward, and finally stopped in mid-air, where they could see a huge steel hand like a kuafu's arm slowly exerting force, and the box containing Nanhai No. 1 was lifted out of the water.

Du Ruhui had already closed his mouth, but still sighed:

"There is an end to manpower, and the power of science is like opening up the world."

For this shipwreck, everyone can guess that the future generations have ideas, but they didn't expect this hand to be so heroic!

As the scene turned, the wreck had changed places, lying quietly in a new pool, and the light curtain had been closed again, allowing them to take a closer look.

[During the Song Dynasty, especially the Southern Song Dynasty, it was extremely dependent on the Maritime Silk Road.

At that time, the Song Dynasty had a large gap in domestic demand and foreign trade, and the population began to recover, but there was not enough land, so merchants and craftsmen became good choices for the people, which in turn promoted the development of commerce.

The navigation of the Song Dynasty can basically be said to start with the compass and finally seal the cabin.

Both the "General Essentials of the Martial Arts" and Shen Kuo's "Mengxi Bi Tan" record the production method of the compass, which can be relied on to complete some offshore voyages.

Relying on the compass guarantee, the monsoon law, the preliminary drawing of nautical charts, the prediction of the weather at sea, the astronomical observation, the hydrological survey of the near water, the sea contact and other navigation techniques are all brightened up one by one.

After the Southern Song Dynasty further lost its territory, the Southern Song Dynasty's dependence on maritime trade was further increased, and finally the technology of the sealed cabin, which was far more than that of the West for hundreds of years, was finally pointed out. 】

The narration of this light curtain can be called illustrated and illustrated, even if Empress Ruchangsun is interested in watching it, and understands most of it.

For example, the compass is very easy to make, and the small person can put it on the fingernail to observe the direction, which is very convenient.

As for the sealed cabin, it looks even simpler, and even a little confused:

"How can such a simple concept of transformation be able to stumble on it for hundreds of years?"

Empress Eldest Sun was very quiet, just whispering to Li Shimin.

Li Shimin motioned to the courtiers to copy and study this part of the content, and then turned around and shook his head and said in a low voice:

"Isn't that also the art of engraving? The method of inscription was already in the pre-Qin period, but it ......"

Empress Changsun nodded, the engraving printing technique and the inscription technique are also internally connected, but if it weren't for Cai Hou's paper, this step would not take many years to take a step.

Then he looked at the light curtain side by side with Li Shimin.

If the skills of the Song Dynasty only made her feel convenient, the skills of later generations can be called miraculous.

In addition to the connection between the four major inventions, the Song Dynasty also began to try to systematically study and study the world.

For example, in the early Song Dynasty's "Easy Learning and Discernment", it is said that there is righteousness outside the imperial examination, physics outside righteousness, and life outside physics.

Since then, the research of the literati of the Song Dynasty has been varied, and it can be said that it covers quite a lot of aspects.

For example, after Cheng Hao once went to sea to watch the stars, he tried to calculate the distance from the earth to the moon, although because his understanding of the universe was not completely wrong at that time, it was also a step forward in astrophysics.

In "After Attaching East Records", Cheng Hao demonstrated the speculation of longitude and latitude from the relationship between plant growth and maturity and temperature based on the fact that he ate leeks in three places in Zezhou during his three months in Zezhou, which can be regarded as getting involved in geophysics.

Later, Shen Kuo recorded his miscellaneous research at that time in "Mengxi Writings":

Volume 3 records the study of colloidal solutions in the chemical category based on the study of the Jiezhou Salt Pond; Volume 6 examines the principles of acoustic resonance as well as the principles of resonance, based on playing two identical lutes in an empty room.

Volume 19 examines optics in physics based on copper translucent mirrors; At the same time, Shen Kuo also corrected the errors in China's first anatomy of human internal organs.

Shen Kuo is even more powerful in his astronomy, improving the armillary sphere that measures the orientation of celestial bodies, measuring the length and shortness of the true solar day, observing and recording the trajectory of the five stars, measuring the true distance between the North Star and the North Celestial Pole, and obtaining the most accurate results in the world at that time.

In addition, his research also involves geographical topography and cartography, as well as water conservancy, medicine, military, calligraphy and painting.

After Shen Kuo, the representative figure in mathematics research was Qin Jiushao, who studied the numerical solution of higher-order equations, the coincidence solution method and the improved multiplication and division algorithm, and finally compiled the "Nine Chapters of Mathematics", which is one of the pinnacle achievements of traditional Chinese mathematics. 】

If you talk about physics, optics, astronomy, etc., Kong Ming can barely understand some of it.

Then even if he is as smart as him in the mathematics part, he has experienced the feeling of listening to heavenly books for the first time.

Pang Tong looked at Kong Ming and frowned, and said cautiously:

"Kong Ming is confused?"

Kong Ming looked at the research content called Qin Jiushao, his eyes were full of confusion, and finally shook his head very sincerely:

"Liang doesn't understand this math."

Not only Pang Tong breathed a sigh of relief, but for a while, Zhang Song, Liu Ba, Liu Bei and others also breathed a sigh of relief.

Pang Tong relieved the siege and said: "Hey, the knowledge of this later generation is so profound, we are separated by hundreds of years, and it is really difficult to achieve!" ”

Liu Ba, Zhang Song and others all nodded and felt the same way.

Kong Ming shook his head slowly, he read the scriptures to the fullest, and he still knew a little about astronomy, so he looked at the general description of astronomy, as well as the previous light curtain to zoom in and out of the map.

Kong Ming already had a little guess in his heart, the land of Shenzhou under their feet seemed to be a huge ball?

But...... How does this make sense?

Although it is good to know how many complicated disciplines there are under this science, ......

Kong Ming tilted his head up, and for the first time, he was full of confusion.

……

Li Shimin looked left and right, in fact, starting from that physics, he couldn't understand all this part of the content.

As for the back, Li Shimin understood two parts, Shen Kuo, Qin Jiushao, gone.

As for the picture that appeared like a ghost painting symbol when Qin Jiushao was introduced, Li Shimin was directly shocked: This is my Chinese script?

So I simply went to see the reaction of the courtiers.

Wei Chi Jingde's eyes were wide open, and a pair of tiger eyes were full of ignorance.

Li Shimin nodded secretly, very good, I'm not alone!

Li Jing and Li Shiyun whispered, Li Shimin listened attentively, and couldn't help but laugh dumbly.

The two generals have given up on treatment, and are arguing about which of the cannons or the Dongfeng Express is easy to use.

Although Dongfeng Express looks shocking, Li Shiyun thinks that it will cost a lot of money, but the cannon looks like it is very easy to pour.

He even agreed with Li Jing that after the end of the show, he would "visit" a few Taoist temples and knock out the gunpowder formula.

Shook his head helplessly, this is like the temper of his own general.

On the other side, Fang Duwei and the three of them were like frosted eggplants, hanging their heads.

Seeing Li Shimin, he complained one after another:

"Everyone, is this mathematics really the words of China? Why is it completely incomprehensible when put together? ”

"The difficulty of this mother of science is truly extraordinary, your ...... No. ”

"Your Majesty, the ministers know the people's livelihood, water conservancy, and ancient books, but I really don't know this mathematics, and I hope that Your Majesty will summon talented people to study it."

Li Shimin laughed, and his laughter was full of a kind of sympathy between the illiterate and the illiterate.

[The research of the sages is basically like this, just as the so-called success does not have to be me, and the same is true of science.

On this road, some people are immersed in hard work, some people are desperately working hard, and some people sacrifice themselves to seek the Fa.

For example, Tao Chengdao of the Ming Dynasty did not hesitate to die in order to test the flight.

In modern times, on the basis of the sages, mathematics is used as a tool to synthesize physics, astronomy, materials science, mechanical engineering, fluid mechanics, electromagnetism, space attitude dynamics, and so on.

We were finally able to go to the outside of the cradle of the earth. 】

The Ganlu Hall and the Chengdu Mansion were all staring at the light curtain.

As for the person named Tao Chengdao on the light curtain, they didn't have time to comment yet.

As soon as the picture turned, I saw a huge, like Dongfeng Express, with a sharp blade pointing to the sky!

Celestial flames erupted from its tail, and the blade slowly rose into the air.

A question arose in the hearts of people on both sides: Where is this going to be hit?

But soon there was no such doubt, they watched this thing get higher and higher, piercing the sky, breaking through the Gangfeng, and it continued to rise!

The picture in the light curtain was covered with a layer of white mist, and then they tried to break through, and there was no more obstruction, and what appeared in front of them was an endless space with stars and flickering.

"There is a house in the sky, is it an immortal?" Zhang Fei asked stupidly.

Everyone saw a white, weird house floating from the other side.

At this time, the light curtain also answered this doubt:

[Welcome to China's International Space Station: Tiangong]

The light curtain now turns downwards again, and a blue planet comes into view.

[Come and say hello to our Mother Earth.] 】

Although it is late, it is a special situation today, and I am still embarrassed to be disconnected. This chapter is still counted as the 4th, and tomorrow will be a double update.
