The change of atmosphere, the speed of changing faces.
Stunning.
Situ Kong, an old man who was accustomed to the world, couldn't help but murmured for a while, but in the end, he still said: "Liu Zhizhou, please!"
"Hahahaha, let's go!"
Liu Zheng waved his hand.
Jie Yu was dumbfounded at this time. Is it that simple to co-author? This Liu Zhizhou’s character is really...
Naturally, these people cannot take the "elevator" up the mountain.
As for the academy, they naturally wanted to give Liu Zhizhou a shocking effect at this time.
A young man behind Situ Kong whistled, and several ships came galloping from all directions. Although the boat is small, it is extremely fast. And it's so fast that it's amazing. If you look carefully, you can see that the stern of the ship actually has a unique setting, equipped with ship wings. The ship wings roll in the water, giving the ship power. The design is so ingenious that even Liu Zheng's eyes lit up.
He knew that there must be no motors in this era.
But to be able to use wooden mechanisms to create such exquisite ship wings, this person must be a great talent in the art of mechanism.
Likewise, he is also a master of mechanical physics!
Isn't this the talent he wants to pursue?
As if sensing the slightest surprise in Liu Zhizhou's eyes, the young man behind Situ Kong couldn't help but snorted coldly: "Liu Zhizhou, how does this ship compare to your Yinzhou ship?"
"Zhang Yang!"
Situ Kong couldn't help but drink, with a look of displeasure on his face.
Liu Zheng then noticed that the young man was about the same age as himself, and he looked suave and stylish. There must be many aloof and outstanding people in this academy, and Liu Zheng had already been mentally prepared.
So facing this provocative look, he just smiled and said calmly: "There is no comparison."
When Zhang Yang heard this, he couldn't help but raise his lips: "That's right, this is the masterpiece of our third senior brother! It is known as the fastest ship in the world..."
Liu Zheng shook his head: "I mean, there is no comparison between your ship and the Yinzhou ship."
"you……"
"What did you say?"
"Shameless talk!"
Zhang Yang looked angry.
Situ Kong also smiled, wanting to see how Liu Zhizhou would retort.
At this time, they were already on a boat. This kind of fast boat could accommodate nearly ten people. On this ship, there are naturally Liu Zheng, Qin Changfeng, Pei Qianyun, Pei Yanran, Situ Kong, Jie Yu and others. There are only a few left. It is conceivable that their status in this academy will not be low.
Zhang Yang's status in the academy is naturally not ordinary. He was different from other people who came to the academy to escape from the world. He was born into a noble family, and he was the son of a wealthy family in the south of the Yangtze River. After arriving at the academy, he and his seventh senior brother Chen Ran had a similar affinity, and they both enrolled in the strategy department. Therefore, how could he not be angry when his favorite senior brother was killed by the man in front of him? It is perfectly normal for you to dare to bombard the academy and make taunting remarks today.
Liu Zheng chuckled: "I don't know if the third senior brother you mentioned has ever tried to use his machine skills to drive a larger ship. But I think that a small boat with ten people is already the limit of his machine. The wooden gears and The weight that the mechanism can carry is ultimately limited. Steel is the direction of future development, so this ship has already been finalized and it is difficult to do anything else. The Yinzhou ship is different. At the beginning of the design of the Yinzhou ship, there were The power mechanism has room for flexibility. With the upgrade of the power mechanism, the Yinzhou ship can still be modified."
"So you said, is this comparable?"
As soon as these words came out, Zhang Yang's expression immediately changed.
Situ Kong's eyes lit up and he asked, "What does Liu Zhizhou mean..."
Liu Zheng laughed: "The gear is just the transmission, the source of power is the key!"
This is why he came to the academy... Over the years, the Chinese nation has actually made breathtaking achievements in machine arts and mechanics. For example, in the application of gears, as early as the Spring and Autumn Period and the Warring States Period, bronze gears appeared. The compass car and the drum car that appeared in the Chinese period already adopted the gear transmission system. The water-rotating continuous mill invented by Du Yu in the Jin Dynasty transmits the power of the water wheel to the stone mill through gears.
During the Tang and Song dynasties, the use of gear power transmission devices had reached its peak.
However……
Only in terms of source of power, the Chinese nation is not in a leading position in the world. Moreover, it can be said to be quite backward... Especially during the first industrial revolution, the emergence of the steam engine directly threw this country away in terms of science and technology.
simply put.
Mechanism is the science of physics.
The source of motivation is chemistry.
But in ancient times, they were collectively called "Gewu"!
The mechanism technique was revered by the Mohists, and then Liannu, Wooden Ox and Flooding Horse all used the mechanism technique to the extreme.
The Mohist organ technique has influenced Chinese history for many years and is undoubtedly the crystallization of human wisdom.
However……
In Liu Zheng's opinion, it is precisely because of this mechanism technique that has been passed down for so long that people are too addicted to the requirement of wisdom. On the other hand, it affects the "simple and rough" pursuit of source power.
This resulted in the Chinese nation being beaten passively in the end.
The reason why Western society can rise rapidly is that it has mastered relatively direct power sources. When steam engines, oil, and various simple and crude power sources appeared, the world structure began to tilt.
And what about Liu Zheng?
This time I came to Liangshan to do two things.
Chemistry and physics, you need to grasp it with both hands, both hands need to be strong!
On the one hand, let Rhodes help him recruit Western talents.
On the other hand, he wants to win over the academy's geniuses.
When physics and chemistry were combined, he could imagine that his scientific field was about to take off!
"Power source?"
Situ Kong listened thoughtfully.
Liu Zheng smiled slightly and stopped talking.
"Humph, you're trying to be mysterious!"
Zhang Yang naturally refused to give in and shouted coldly: "My third senior brother, who is said to have written half of the "Mo Jing", is he worse than you?"
Liu Zheng's eyes lit up when he heard this: "Really? Today, I have to meet you, the third senior brother, first!"
"Mo Jing"!
This is a palace-level ancient book on Chinese physics. Among them, there are six chapters: "Jings 1", "Jings 2", "Jingshuo 1", "Jingshuo 2", as well as "Daqi" and "Xiaoqi", which are devoted to interpretation and time, space, material structure, mechanics, and optics. , acoustics, algebra, geometry and other contents.
"Mo Jing" represents the highest peak of Chinese scientific development.
In terms of mechanics, the "Mo Jing" puts forward the definition of mechanical motion as: "Motion, domain migration."
This means that the essence of mechanical motion is the movement of the position of an object, which is completely consistent with the definition of modern mechanical motion.
At the same time, the Mohist school mastered the law of leverage two centuries earlier than Archimedes.
In terms of optics, among the vast number of classical and historical works in my country, "Mo Jing" is the only classic that systematically discusses the development of geometric optics in ancient my country.
The "Mo Jing" records the world's earliest "small hole imaging" experiment conducted by Mozi and his students, and provided insightful insights into the experimental results. This was the first scientific explanation of the propagation of light along a straight line. In terms of mathematics, the "Mo Jing" puts forward some definitions of geometry, such as the definition of a circle in the "Mo Jing" cited in middle school mathematics textbooks: "A circle has one center and the same length." This is similar to the circle in modern mathematics. The definition of "the locus of points equidistant from the center point" is completely consistent.
Half of the Mo Jing?
Good guy!
Liu Zheng is becoming more and more interested in this academy!
