Chapter 111: Mozi's Three Laws

Mingyue advocated Mozi, not to please the Mo family's disobedient theories, but to admire this sage from the bottom of her heart. Pen | fun | pavilion www. biquge。 info

He vaguely remembered that not long before his crossing, China launched the world's first quantum science experiment satellite, which was called "Micius"! The reason why it is named "Mozi" is because Mozi proposed the concept of "end", which refers to the smallest unit of space that cannot be divided, which is actually particle theory and belongs to the category of quantum science. His pioneering work should be manifested in this way.

After returning to the Warring States Period, after reading several volumes of the "Book of Ink" from Tian Jia, who has a deep relationship with the Mo family, Mingyue found that this sage's contribution to science did not stop there......

In terms of optics, Mozi was the first in the world to discover that light propagates in a straight line with the experiment of "small hole imaging", and expounded the imaging of shadows, plane mirrors, concave mirrors, and convex mirrors, explaining the relationship between focal length and object imaging, which is more than 100 years earlier than the optical records of ancient Greek Euclid (about 330~275 BC). What is surprising is that these theories, which are recorded in the "Book of Ink" and called the eight rules of optics by later generations, were verified by the surface of the water and with copper in the absence of glass.

In terms of mathematics, as an old craftsman who draws with rules all year round, Mozi proposed three definitions, namely, "times, for two", "flat, the same height", and "circle, one in the same length". These three definitions correspond to the "times" of modern mathematics, the "equality of perpendicular lines between parallel lines" of Euclidean geometry, and the definition of circles.

In terms of mechanics, Mozi has made great achievements, and he proposed: "Force, the reason why punishment (form) is also striving." That is to say, force is what makes objects move, and by the way, the concepts of gravity, gravity, and reaction force also appear in the Book of Ink.

In addition, Mozi also made a precise summary of the principle of the lever, 200 years before Archimedes.

Mozi was not only a theorist who was good at summarizing, but also a practitioner, who spent three years meticulously developing a "wooden bird" that could fly, and could build a car with a load of 30 stones in less than a day, which was fast and labor-saving. He was well versed in the manufacturing techniques of various weapons, machinery, and engineering construction at that time, and he was very innovative. Mingyue's "Preparing the City Gate" and other articles that she can't see in the "Book of Ink" talk about various advanced city defense techniques for the enemy. This is an untold secret within the Mo family.

It can be seen that judging from these achievements alone, Mozi is not only Newton of the Warring States, but also Da Vinci of the Warring States! Coupled with the imagination of electing a sage as the king through layers of election in "Shangxian", Mingyue almost thought that Mozi was also a traveler.

Who said there was no science in ancient China? In the Warring States period, these things proposed by Mozi were hundreds of years ahead of the times.

However, Mozi's achievements were very tortuous, and the successors of the Mo family did not pay much attention to this part of the "Book of Ink", and few people studied it. When a Qin fire came, the Moxue works were also affected, and there was not much left. After Emperor Wudi of Han respected Confucianism and deposed the Hundred Schools, the Mo family completely declined, and then these things were forgotten by the Chinese for two thousand years.

It was not until modern times, when gunboats forced the door and the West learned from the East, that the Chinese opened their eyes to the world, planned to master the skills of Yi to control Yi, and desperately translated various scientific books. While admiring Newton's greatness and fascinated by those Western laws of physics, they suddenly discovered that our Mozi had proposed these things as early as the Warring States Period!

It is conceivable that the scene was very embarrassing at that time, it turned out that it was not that the ancestors were not smart, but that the later students were not angry!

Those who ruined Mozi's achievements, whether they were emperors or generals or not, how much praise and fame, Mingyue felt that it was not an exaggeration to call them historical sinners!

Now back to the Warring States Period, back to the era when the Mo family had just slipped from its prime, Mingyue of course had to praise Mozi without hesitation, and he even learned from the Mo family and called it "Zi Mozi", which means that Mozi is regarded as the first teacher of enlightenment.

Now, the Mo family was overjoyed.

……

"Chang'anjun respects Zi Mozi so much, my Mo family can't belittle him anymore."

The Mohist family once flourished, and it was ranked with Confucianism all over the world. However, with the fragmentation of the Mo family, they have been in decline for many years, not to mention the world's outstanding learning, and the Oriental Mo masters of the Qi Kingdom have some difficulties in even fighting for a place under the Ji.

If Chang Anjun was just an unknown person, and he promoted the Mo family like this, the Mo family would not take it seriously, but would keep his distance from him. Although the two parties had been hostile before, the Mo family had pinched their noses and proposed Yao Shun Chan Rang together with their sworn enemies Confucianism, and not long ago they also opposed Chang Anjun together with Confucianism and the Yin and Yang family.

The battle of the Nine Streams and Ten Families is the same as the Seven Heroes of the Warring States Period, today you and I work together, tomorrow we suddenly turn against each other, and there has never been an overnight feud.

Therefore, it is normal for the two sides to reconcile now.

Chen Qiu, the leader of the Mo family, and Chang An Jun approached at an extraordinary speed, and after negotiating a few times, the front gap disappeared, and they hit it off!

After all, Mingyue only said that rainfall was a natural process, and did not openly deny the existence of ghosts and gods, and had not yet touched the bottom line of the Mo family. So the Mo family also began to agree with Chang Anjun's "three states of matter" theory, which has some truth.

Mingyue reciprocated with a peach and began to spare no effort to advocate Mozi's doctrine.

He openly stated: "The sun rises in the east and sets in the west, spring, summer, autumn and winter alternate, the water condenses into ice, the ice melts into water, and the rivers flow eastward...... These inevitable things are called axiomatic laws, and Zi Mozi has proposed countless axiomatic laws! ”

At his instigation, in order to let the old trees of the Mo family sprout, the Mozi began to reorganize the "Book of Ink", and sorted out the Gewu theory proposed by Mozi one by one, and divided it into "Eight Principles of Optics" and "Ten Types of Mechanics", collectively known as "Mozi's Gewuxue".

Mingyue also chose these theories, and gave those that were similar to the concepts of later generations the title of "laws".

"Aperture imaging can be called the first law of Mozi optics, that is, light travels in a straight line."

"Mozi said, stop, for a long time, for a long time, not for a long time, when the cow is not a horse. It means that the cessation of the motion of the object comes from the action of the resistance impedance, and if there is no resistance, the object will move forever. This can be called the first law of Mozi mechanics......"

Then, Mingyue used the logical symbols that Gongsun Long had popularized in the Academy Palace here.

Mozi also said: The reason why the scale rod is balanced when weighing objects is that the short standard is long. It is marked as a force arm, which is a moment, and the force × force arm = heavy × moment. It can be called the Mozi lever theorem......"

Mingyue went on to propose that "practice is the only criterion for verifying truth", and that any law needs to be tested by experiments, and the Mohists readily agreed, they were originally a group of positivists who loved to engage in experiments, and they all blindly believed in Mozi to the point that he would never be wrong.

So, with the assistance of Chang Anjun, the Mo family was busy, and the small hole imaging test, the slope trolley slide test, the lever test, and the three tests were held in the school palace one after another, all of which were successful, and the other nine streams and ten families were stunned, but most people were still full of doubts.

No objection was raised, including Confucianism, because most schools of thought were obsessed with rhetoric and had little empirical evidence, and felt that these tricks were no different from the tricks of advocating excellence. Except for the so-called "Mozi Lever Principle", which can be used to explain the operating principle of orange trees, trebuchets, etc., there is no practical significance at all.

In particular, the Confucian Teng Geng faction is laughing loudly and saying that Chang Anjun and the Mo family are playing these strange and obscene tricks, purely to grandstand!

As a result, as soon as the three laws of Mozi came out, they were not amazed but ignored.

For this situation, the Mo family, who worshiped Mozi's posthumous works as gods, was naturally angry, and Mingyue also took the opportunity to propose to do an experiment that shocked the entire Linzi City, so that the corporal and ordinary people who disagreed with them could feel the charm of "Gewuxue".

"Two copper balls, one big and heavy, one small and light, are put down at the same time on the highest platform in Jimen, who will land first?"

As the questions raised by Chang'anjun and the Mo family were thrown to the people of Linzi, an experiment that went down in history began in Linzi Jimen......
