In the process of education, many of the above and other things experienced are very funny and helpless, but they are real. &. {23} {wx}.

The development of society and the progress of mankind will often happen like this! China's culture is broad and profound, but it is not omnipotent, and of course it is necessary to absorb advanced ideas and technologies. If you want Huaxia to dominate the world, you must have the courage to analyze yourself and dare to face your own shortcomings! Instead of deceiving oneself like Ah Q, this is the most important thing.

Therefore, this is also the ultimate purpose of Li Guo sending Viscount Lida to Europe to find talents, and this is only the beginning. Li Guo will also do this often, and Li Guo will let all the advanced ideas and technologies be used by the Chinese people.

For the beginning, many generals did not understand Li Guo's approach. Li Guo will explain to them patiently and meticulously. Fortunately, after a long time, after the benefits of this practice were slowly revealed, more people sincerely supported Li Guo, rather than simply because they were loyal to Li Guo at the beginning.

Among them, the fastest results should be physical and chemical.

Physical phenomena are among the most common phenomena that occur in nature. It not only accompanies human life and production activities at all times, but also affects human life and production activities.

In fact, the exploration of this aspect in ancient China has been carried out very early.

For example, the early works "The Book of Ink", "Examination of the Gongji", "Mengxi Writings", and "Grass Elephant Leather Book" are representative works of ancient physics knowledge. In addition, China invented and manufactured a large number of scientific instruments and practical production and living tools in ancient times, such as armillary spheres, geodynamic instruments, compass keys, drums and a variety of musical instruments. They are all made according to certain physical principles. Therefore, with the circulation of various books, theories and objects, the physical knowledge in them was also unconsciously imparted.

But. In the long feudal society, due to the constraints of private learning and the imperial examination system, school education emphasized ancient literature and history, and neglected natural science, and physics had not yet formed an independent discipline system at that time, so school physics education in the real sense had not yet been formed.

In contrast, the achievements of Western physics are much more advanced.

For example, early Western statics. as well as the principle of leverage and Archimedes' law, among others.

However, it was only after the sixteenth century that the industrial progress of capitalism in the West really began to create the material conditions for natural science research in the Western world, especially the rise of the maritime industry in the Age of Geographical Discoveries. Mankind has devoted unprecedented effort to observing astronomy, and the Danish astronomer Tycho has spent more effort than ever before. Brach and the German astronomer and mathematician Johannes. Kepler's writings and expositions on behalf of others opened a new chapter in physics.

For these, Li Guo couldn't be more familiar with them. Because he himself is a concurrent physics and chemistry department.

for the importance of physics and chemistry. Li Guo is very clear.

Therefore, Li Guo deliberately took a month of precious time to conduct a systematic and cramming education for the students of the entire academy, as well as scholars and craftsmen from the West.

Of course, things like Einstein's theory of relativity and the like, Li Guo didn't mention it. It's better not to talk about those advanced things, lest these people go crazy!

But just get started. People have gone crazy!

After Li Guo said that the earth was round, the Westerners in the West were not shocked. Because in 1622, the circumnavigation of the world led by the Portuguese navigator Magellan proved that the earth is indeed spherical.

But the students and the teachers of the academy are all Chinese, and they are strongly opposed to this.

Even Nie Xin stepped forward and whispered to Li Guo mysteriously, "Master Hu, let's not talk about it, who doesn't know about the round sky?" You say that the earth is a ball, isn't that nonsense? ”

"Go! While listening. Li Guo drove Nie Xin back. But Li Guo didn't explain, and he was going to let those scholars from the West explain this issue, which would save much effort.

But after the second knowledge was spoken, almost everyone objected!

That is, both geocentrism and heliocentrism are wrong! At this time, Westerners have also raised objections.

However, these things will not be understood by them for a while, Li Guo just forced them to write down all this knowledge to me, and you will study it slowly in the future.

Why did Li Guo talk about these inconsequential things, because in physics, the most important mechanics are inseparable from these.

Mechanics is the knowledge that Li Guo can really use now.

The four laws of mechanics are to be talked about, the first law ~ the law of inertia, the second law ~ the law of gravitational acceleration, the third law ~ the law of force interaction, and the fourth law ~ the law of universal gravitation.

Li Guo used the familiar launch cannonballs to speak. When the gunpowder in the barrel explodes, it creates an interacting force that shoots the shell out.

Because of the acceleration of gravity, the cannonball can be fired farther.

But why did the shells fly forward when they flew out of the barrel? Because of inertia.

But why did the shells end up on the ground? Universal gravitation.

Including the four laws of heat, Li Guo talked a lot.

These may seem useless, but these laws are instructive for future technological innovation.

But all the people have already heard it. Only a handful of Westerners seem to be inspired.

Li Guo is not afraid that you will be confused, Li Guo's request is for everyone to record. Once these people's heads are opened, it will be amazing.

Moreover, if these laws had not been proposed, Newton in England would have proposed them in a few decades. Because Newton, in his 1687 paper "The Laws of Nature", described the gravitation force and the three laws of motion. These descriptions laid the foundation for the scientific view of the physical world for the next three centuries and became the basis of modern engineering.

Therefore, Li Guo should be the first to put it forward. Science is decades ahead, and that's a big deal.

Li Guo talked a lot about what machinery manufacturing, including the principle of steam engine, although Song Yingxing had built a forging machine driven by a steam engine, this was far from enough.

What Li Guo wanted was a revolution, an industrial revolution launched in China!

To say that Li Guo's things have attracted some Western scholars, there is also one Oriental who is extremely interested in this, that is, Song Yingxing.

Since Li Guo started to lecture on physics, Song Yingxing has grown up with Li Guo, and has been studying with Li Guo tirelessly in vain and night.

Well, Li Guo nodded, is his attitude okay.

"Ying Xing, can you understand my things?" Li asked.

Song Yingxing shook his head, "No, but after the steam engine and forging machine are made, I know that what you said must be useful." ”

"Okay, Ying Xing, with your attitude, I'll teach you everything I know!"

So, with his infinite trust in Li Guo and his rote memorization, Song Yingxing finally really became a master of physics, and really created the tools and weapons that Li Guo needed to dominate the world. However, these are for the future and do not need to be revealed now.

In addition, Song Yingxing's "Heavenly Creation" is no longer the original content, but a large encyclopedia that contains everything in the world! (To be continued......)
