Great Song

This wave caused by the "rotation of the earth" has indeed swept through Shih Lin, and even attracted many people who are dissatisfied with the "art of war" and tried their best to use bullets, saying that Zhang Zaide was uncoordinated and disturbed people's hearts.

How could Zhao Xu, the emperor, not know these waves?

In fact, as early as after the high platform was erected outside the Daxiangguo Temple, Zhao Xu became curious and hung a similar pendulum in the highest Mingchun Pavilion in the Royal Garden.Although it is only ten feet high, its deflection direction is the same as that in front of Daxiangguo Temple, which makes Zhao Xu amazed.It's not like he hasn't asked the master craftsman in the prison, what is the reason for this?But no one could answer.This thing can only be placed in the imperial garden as a "miracle", even the empress dowager and concubines in the palace can't help but go to see it.

A well-endowed decoration suddenly became a clear proof of "the rotation of the earth".Zhao Xu was so choked that he almost didn't come up.

He believed in the "interaction between heaven and man" the most, but "Baihu Tongyi" never mentioned this matter!Moreover, the rising of the sun and the setting of the moon have nothing to do with the sun and the moon, but have something to do with the earth. No matter how it sounds, it sounds weird.

Zhao Xu didn't dare to neglect, and immediately called Wang Anshi to ask questions.Facing the emperor's question, this minister who seemed to be omnipotent also remained silent for a long time, before he said: "This matter is a celestial phenomenon, why don't the officials ask Shen Kuo, the superintendent of heaven, to ask the right one? obtained."

How could Wang Anshi not know about this turmoil? Although he was surprised, he had no fear.I don't even want to see Zhang Zai, who supports the new law, be implicated.As far as he knew, Shen Kuo, the chief of the Sitianjian, knew a lot about the celestial phenomena, and it was rare that he dared to do things.In Sitianjian, he can also be determined to innovate and promote talents.If such a person can support the earthquake theory, he will certainly be able to convince the emperor.What's more, the sky-watching mirror is indeed rare. He has also read some records of the Si Tianjian. Now that he thinks about it, it can be related to the "earthquake".

Zhao Xu reacted immediately, yes, he also went to the observatory himself, and saw the moon and stars with a skyscope.What you see in the sky mirror is very different from what you see with the naked eye.Maybe Shen Kuo can really answer such important matters.

Soon, Shen Kuo was transferred to the Chuigong Hall.Facing the Son of Heaven and Mr. Xianggong, he only hesitated for a moment and said: "This matter should be true. This year, I have used the sky mirror to measure the age star. The age star is also a sphere, and there is a big red spot on the surface. This red spot is not motionless. Instead, it has to go around once every five hours. It can be seen that the Sui Xing is also rotating. If the Sui Xing is like this, it is not surprising that the earth under our feet will rotate on its own."

Hearing this, Zhao Xu was even more shocked.The year star is also turning? !Is it possible that all the stars in the sky have to rotate?What should the trajectory of the stars look like?

After hesitating for a long while, Zhao Xu said: "But isn't the way of heaven on the left? The sun and the moon travel westward, and the river flows eastward, so the sky rotates to the left, and the earth circles to the right, just like the yin and yang of the monarch and his ministers. Is there something wrong with this?"

Shen Kuo hesitated for a moment, before he said: "The river flows eastward, but it is caused by the terrain. Instead, the water flows into a whirlpool, which is most likely related to the rotation of the earth. The sky is more than billions of stars, and the stars move day by day. It is unbelievable. Maybe the heavens The stars are all the same as the old stars, they have a trajectory and rotate on their own, and follow the way of heaven."

These words made Zhao Xu fall into deep thought, and after a long time, he asked softly: "What about the moon? The moon has cloudy and sunny cycles, doesn't it turn around every [-] days?"

"The moon revolves around the earth, just like the weft star of the year star. Because it is too close, the speed is fast, and the back is against the sun, it becomes a circle." Shen Kuo suddenly raised his head, "The way of heaven has its own laws. Since it is visible, you should not hide it! "

This is almost a direct remonstrance.

Zhao Xu's heart was still in a mess, but Wang Anshi said, "Since it is the way of heaven, the officials should not worry about it anymore. The sun and the moon have risen and set as usual for thousands of years, and they have never changed. Among them, the secret can be given to the officials." The income is precisely because the officials can appoint talents and use their abilities, so is it not auspicious?"

These words moved Zhao Xu's heart.Yes, no matter what the "Bai Hu Tong" says, the sun and the moon rise in the east and set in the west, but they remain the same.Maybe it's just that the editors misunderstood what the sages meant by "the sky rotates to the left and the earth rotates to the right", which makes the world confused?The notes and scriptures of each generation are different, and it is not surprising that some people make it far-fetched.

But in this dynasty, some officials discovered what the world should look like, and reinterpreted the scriptures. This should be a good thing, not a bad thing.

Thinking of this, Zhao Xu nodded slightly: "What Wang Qing said is not bad. Since the stars rotate on their own, it is not surprising that the earth rotates. It's just that Hun Tian said that he might change his face."

"In the Tang and Han dynasties, Huntian also replaced Huntian. Now that Xuanye is replacing Huntian, it is Fagu, who is closer to the way of heaven." Seeing the emperor's intention, Wang Anshi immediately said firmly.

This statement immediately made Zhao Xu smile: "It makes sense. It is the right thing to rebuild the calendar. Now I add the earthquake to make the calendar more accurate. Shen Qing, Si Tianjian's new calendar, editor How is it?"

Shen Kuo lowered his eyes slightly: "The revision of the calendar is difficult, and it may take some time..."

Hearing this, Zhao Xu didn't take offense, and nodded with a smile, "You just need to cultivate slowly, and the saying that 'the earth is the heart of the universe' also needs to be paid attention to constantly. If you find anything, you can report it directly. .”

Shen Kuo's expression froze, and he lowered his head, half covering his face with his raised hands: "Minister, obey the order."

■

Since the emperor didn't pursue it, Zhang Zai's statement of "earthquake" has gained a firm foothold.In addition, Cheng Yi, who previously advocated the "Huntian Theory", left Beijing quietly, which made the opponents, who were still very vocal, a little bit unable to resist.

Su Shi was very happy about this situation: "Although Zhang Zihou changed the law arbitrarily, he has a solid foundation in Confucian classics. In the study of qi, the theory of learning etiquette, righteousness and morality, and cultivating qi to gather righteousness is also very suitable to me."

Su Shi did not agree with the "Art of War".This kind of attitude of encouraging the emperor to be militaristic is deeply annoying to him.But Zhang Zai's "qi study" really made Su Shi greatly appreciate it.After all, in the lineage of "Qiology", whether it is the explanation of "Qi generates all things" or "vacuum", it is almost the same as what Su Shi thought.Even the idea of ​​cultivating awe-inspiring qi, changing temperament, and returning to the original for good is similar to the Su family's view of "nourishing qi and curing the heart".

Not to mention the "Earth's rotation" theory that I discovered now. He was almost forced to die by the "Huntian theory" before. Unexpectedly, the "earthquake theory" suddenly popped up, and it was immediately perfected. The loopholes in "Xuan Ye's theory" also caught the group of guys clamoring that "gravity is light in the east and heavy in the west" by surprise.Now no one dares to question the point of view of "Xuan Ye Shuo", how can he be unhappy?

After exaggerating, Su Shi stroked his long beard again: "It's just that I can only turn a sixteenth of a circle when I look at the pendulum for an hour. How can I calculate that it can't turn a full circle in twelve hours? Then Doesn’t the rising of the sun and the setting of the moon mess up the day and night?”

Hey, he understands this question!Zhen Qiong immediately regained her spirits: "This is because the ground is a sphere, isn't there an arc? That's how it should be calculated..."

Isn't Su Song not here today?Of course, this question must be handed over to him!Zhen Qiong scribbled on the paper and told him what Su Song had taught him before.At the end, I marked a dot on the crooked circle drawn, "Look, it's here! Do you understand?"

Su Shi: "...No. Can you say it again slowly?"

Zhen Qiong: "..."

He also has apprentices, okay? Even Mingyue understands it as soon as he hears it!

Feeling that the man in front of him was so stupid, Zhen Qiong dropped the charcoal pencil in dejection, and said to Shen Kuo, "Brother Cunzhong, you should tell him."

Shen Kuo was originally sitting at the side, holding a teacup in a daze, but when he heard Zhen Qiong calling him, he suddenly came back to his senses and looked over.

Su Shi immediately said: "Brother Cunzhong, why does the pendulum of Daxiangguo Temple turn less than one week in a day and night?"

This problem is naturally not difficult for Shen Kuo. He simply explained: "The speed of a pendulum swinging on a flat surface is different from that on a curved surface. The earth is a sphere, so the curvature is not the same everywhere. The endpoints of the two poles are outside the twelve o'clock circle, and the speed and angle of swings in other places will be affected by geography."

He didn't say the algorithm, but Su Shi really understood it: "Then can't we calculate the position of the earth where we are?"

"That's right." Shen Kuo nodded, "It's the place Ling Xiaozi calculated just now."

Su Shi hurriedly lowered his head again, looked at the picture, and sighed: "It turns out that we live in the upper half of the earth. It's really amazing. Isn't it possible to calculate the size of the world?"

"The sun, the moon and the stars can be counted, but it will take time." As the chief of the Sitian Supervisor, Shen Kuo is quite confident about this.

Su Shi laughed and said, "Brother Cunzhong should work harder. It would be even better if he could calculate how the sun, moon and stars go around the earth based on gravity."

These words made Shen Kuo shut up immediately.

Su Shi didn't notice anything wrong, and said: "I heard that the new observatory built by Si Tianjian is also unusual. If a new calendar is made this time, it will be a grand event."

As soon as his words fell, Shen Kuo frowned: "What if the new calendar only counts daily travel instead of monthly travel?"

"What?" Su Shi almost suspected that he had heard it wrong, "How can the calendar not count the moon's movement! If there is no moon, wouldn't there be only the lonely sun?"

Is this still the official of Sitian?You should understand the principle of yin and yang interaction.Besides, if you don't even count the moon, how can you determine the moon?Could it be that he didn't even care about such important tasks as the solar eclipse?

"The calendar is used to keep time. As long as you can calculate the sun's trajectory, you can set the solar terms and help farming. Why bother?" Shen Kuo frowned a little more, and felt that the irritability in his heart was getting stronger.

Su Shi still shook his head: "Brother Cunzhong is too biased!"

"Even if it is included in the monthly travel, it will interfere with the timekeeping and make the year go wrong. Is it okay to have to run every other time?" Shen Kuo asked again.

"Since you can use Zhirun to adjust, why worry about the difference of one or two days?" Su Shi didn't buy it at all, "Besides, the sun and the moon go around the earth, so it's not right to give up one or the other."

ah?Why does the sun go around the earth again?Zhen Qiong raised her head in a daze and looked at Shen Kuo.Didn't it all be announced that the earth will rotate on its own axis, shouldn't it be that someone discovered that "the earth orbits the sun"?Why is it the other way around?Fortunately, although he felt weird, he still remembered the original agreement and didn't say it directly.

That puzzled gaze made Shen Kuo's heart tighten, as if he had been stabbed, causing pain.He didn't speak any more, just picked up the teacup, and continued to drink the tea with a dull head.

Seeing that he seemed a little angry, Su Shi stopped talking about this topic, and talked about anecdotes about the court.It's a pity that the two listeners in front of them were absent-minded, and they all ran away.
