Imperial Master of the Ming Dynasty

As Zhu Di said, Zhu Gaochi directed the two personal eunuchs who came with him to start the operation.

The process of the torsion scale experiment is very simple. It is to place two small lead balls on the same level of the equipment, and then have two people place larger lead balls of a certain weight on both sides of the torsion scale until the gravitational balance of the two small lead balls is broken. , and then judge whether the experiment is successful by observing the movement of the light spots reflected by the small mirror on the metal wire.

The key is to put the two big shot put equidistantly next to the small shot put, but not touching or too far away.

Zhu Gaochi's two personal eunuchs moved very lightly. Under Zhu Di's gaze, they constantly adjusted the position of the big shot put. After several attempts, they finally succeeded in achieving the goal of keeping the two big shot put close to the small shot put and maintaining balance.

However, as the two eunuchs moved away from both sides of the torsion scale, the small lead ball immediately began to twist abnormally and kept shaking back and forth. The light spots reflected by the small mirror on the metal wire also continued to move with the movement of the small lead ball. .

Zhu Gaochi's heart sank, and he realized that there was something wrong with his plan.

Zhu Gaochi immediately called a few good-looking Jinyi guards and asked them to observe the movement trajectory of the small shot put and record the time of each movement and the position of the light spot. After some research, Zhu Gaochi came to a conclusion: the movement trajectory of the small shot put. It is irregular, there must be interference factors, and they need to redesign the experimental plan.

In other words, someone's interference caused the ground to fluctuate. The equipment rack in the darkroom vibrated slightly, and the two small shot balls would sway abnormally.

But this is just a possibility, maybe there is another hidden truth behind it. For example, this metal wire was originally hanging very stably, but due to the influence of the air flow caused by the activities of the two eunuchs, it became unstable, which in turn caused the movement trajectories of the two small lead balls to also change. Change……

In short, if you want to figure out the whole story, you still need to find the "interfering factor".

Then, Zhu Gaochi made some improvements and tests. He directed the Jinyi guards to fix one of the larger shot put near the small shot put with a board, and then did the same on the other side.

However, the two large lead balls were fixed, but the small lead balls remained motionless, as did the light spots reflected by the copper mirror on the metal wire.

Seeing this, both Zhu Gaochi and Zhu Di felt that this so-called "gravity" experiment was probably a disaster.

After all, although the experimental steps mentioned by Jiang Xinghuo were not followed completely, two large lead balls, two small lead balls, metal wires, and a small mirror were all available, and the light spot did not move at all.

Therefore, it is very likely that this so-called "gravity" does not exist at all.

Thinking of this, Zhu Di and Zhu Gaochi's moods became somewhat complicated.

As the ruling class of the Ming Dynasty, the two of them resolutely safeguarded the imperial power. Of course, they did not want any "universal gravity" or "heliocentric theory" to pop up and shake the traditional concept of interaction between heaven and man, thereby affecting the imperial power.

But at the same time, there is also a subtle mentality, that is, the two of them are actually reluctant to believe that Jiang Xinghuo, who has never made a mistake, will make a mistake this time.

The success or failure of the experiment is nothing more than a direct reflection of verifying this result.

Next to him, the third prince Zhu Gaosui watched for a long time and saw that his father and brother were both speechless. He couldn't help but said to Zhu Gaochi: "Brother, what are you doing?"

"If you don't understand, just leave it alone!"

"If you don't understand, just leave it alone!"

Zhu Di and Zhu Gaochi said almost in unison. Zhu Gaosui shrank his neck and hid behind his father.

Zhu Di put his hands in his sleeves and glared at his silly son angrily.

The eldest can write, the second can do martial arts, and the third can eat.

Except that Zhu Gaosui's mouth is tighter when he is not eating than when he is eating, and he seems to be a bit tight-lipped and reliable in doing things. In terms of brain alone, he is probably on the same level as his second brother.

When they were young, the noble children went to school together. One of them was ranked last, and the other was ranked second to last.

Once Zhu Gaojiu stops thinking about it, Zhu Gaojiu will always be the last one.

Looking at the embarrassed third brother, Zhu Gaochi, who was a little impatient because of the failure of the experiment, felt a little annoyed for a moment, and then patiently explained to Zhu Gaosui for a moment.

"Brother, although your method is good, if the big shot put on the board is kept in a fixed place, wouldn't it be able to achieve the effect you mentioned? After all, the gravitational movement of the small shot put is caused by the big shot put. ah."

After listening to his elder brother's explanation, Zhu Gaosui tried his best to open his eyes wide and said.

"What should we do?"

Zhu Gaochi stood for a long time. At this time, he was a little impatient and felt dizzy.

Seeing this, two eunuchs who had served him for many years quickly held him up, one on the left and the other on the right, and then a Jin Yiwei sent him a chair for him to sit down and rest.

Zhu Gaochi also pointed helplessly at the two personal eunuchs and said: "They are already the most dexterous. They usually walk and do things very lightly. Even so, as long as people enter, the stagnant air in the dark room will be disturbed. , the ground will also vibrate slightly. As long as there are these movements, it is impossible to detect accurately, and if other Jin Yiwei were to enter, I am afraid that the movements will be even greater."

"Then what should we do?" Zhu Gaosui asked, "Should we just leave it alone?"

Zhu Gaochi sighed and said with a wry smile: "Let me think about it first, and then try again later. If it still doesn't work, I will think of other ways."

After Zhu Gaochi finished speaking, he waved his hand, and the two eunuchs quickly retreated and walked to the darkroom, waiting for the eldest prince's order before continuing to follow the previous steps.

Zhu Di was pacing slowly and thinking beside him, his face slightly uncertain, and he was obviously troubled.

After a moment, Zhu Di suddenly stopped, looked at Zhu Gaochi and said, "Did Mr. Jiang's steps at that time be different? How should we deal with these two big shot put? It seems that they are not handled by humans."

Zhu Gaochi nodded and replied: "Reporting to my father, Mr. Jiang was talking about placing smooth guide rails on the two to allow the two large shot balls to slowly reach equal distances on both sides."

"Then why not do this?" Zhu Di asked, looking at his eldest son.

Zhu Gaochi explained: "I have tried it before, but it can't be done. As long as it is a sloped guide rail, because the weight of the lead ball is too heavy, it will cause vibrations to the balancing instrument with metal wires and small mirrors hanging in the middle. It is even lighter than a person." The movement caused by light hands and feet is still big."

"What about the one without slope?"

As soon as Zhu Gaosui couldn't help but ask, he roughly knew the result.

"The big shot put won't slide at all without the slope." Zhu Gaochi replied.

Hearing this, Zhu Gaosui couldn't think of any good solution.

Since none of them had any good ideas, they had no choice but to continue trying to manually carry the big shot put again.

The two eunuchs even took off their cumbersome outer robes and shoes, and wore their middle coats with bare feet. They held two large shot put and placed them gently next to the small shot put.

The father and son who were observing outside the dark room couldn't help but look at the results of the second experiment attentively.

After all, what these two big shot put are actually shaking is not the mirror, but the imperial power!

The two eunuchs picked up the big shot put with both hands, stretched it forward as gently as they could, then adjusted the angle to face the padded wooden board, and began to use their arms as fulcrums to hold the big shot put and move it towards the small shot put.

Although this method consumes more energy, it is safer. After all, the small shot put is fixed, and you only need to try your best to keep the big shot put balanced.

However, during this process, the two eunuchs had to move the big lead ball while paying attention to the surrounding environment to prevent the big lead ball from being in the wrong position or colliding with the metal frame to prevent accidents - this kind of operation is indeed a test of arm strength and patience.

Zhu Di and Zhu Gaochi stared at the changes in the mirror and shot put.

The big shot put was placed in a pre-drawn position.

However, the two small shot balls remained motionless.

The two eunuchs were unwilling to give in and once again pushed the big shot put with their arms and moved a few inches towards the small shot put. This time there was finally some movement.

I don’t know if the force was uneven, but the result of the two eunuchs’ efforts was that the small lead ball on the metal frame started to move, swirling in its original position, and rubbing against the metal wire and the mirror, making a thin and harsh sound, but The experiment still yielded no results and apparently did not produce the slightest "gravity".

This made Zhu Gaochi, who presided over the experiment, a little discouraged.

Zhu Gaochi remembered clearly that Mr. Jiang said this experiment was very simple, but it was so difficult for him to do it himself.

If the force on both sides of the big shot ball cannot be balanced, it is estimated that it will be difficult to truly test the fluctuations caused by the gravitational force of the small shot put.

When Zhu Di saw that the two experiments failed, he felt relieved.

There is no such thing as "gravity", which is better for him.

After all, if "universal gravity" does not exist and "heliocentric theory" cannot explain it, then the traditional concept of the induction of heaven and man will not be shaken, and the imperial power will not be threatened.

At this moment, Zhu Gaosui frowned and pondered for a long time, then suddenly raised his head and said: "Brother, father, I have an idea."

"Oh?" Zhu Di looked at his youngest son in surprise, "Tell me about it."

Zhu Gaosui scratched his head and said: "I see people building houses. Sometimes they tie a rope and a cable pulley from the second floor to the first floor, and pass the scrap wood and the like from the second floor directly down. If you want to go to the first floor The same is true for transporting things. Why not use a cable pulley? In this way, as long as the position is aligned, human power will not cause disturbance to the ground and air in the darkroom. "

"Cable wheel?"

"right."

After hearing this, Zhu Di relaxed his brows, showed a smile, and said, "Just follow Lao San's method. You can hang a cable pulley on the beam of the darkroom to fix it, and then pull the rope through the holes on both sides. The person will not go in, and the position is correct. All you need to do is tie the knot in a position and hold it. When it hits the fixed wooden board below, it will naturally be stable. If it still doesn't work, it means that this Lao Shizi's universal gravitational force 'It doesn't exist."

Zhu Gaochi also raised two fat fingers and made a "V" shape and said: "You can also use two wooden boards to nail it, which can just catch the big lead ball."

"go a head."

Zhu Di waved his hand, and the Jinyi guards quickly went down to execute it.

Zhu Di and his son also began to wait for the results of this last experiment.

If this experiment still fails, it will prove that Jiang Xinghuo was wrong the first time

But can Jiang Xinghuo really make mistakes?

A question suddenly popped into Zhu Di's mind that surprised even him.
