"Qin Gongzi, if you have any scruples, just say it, we can refer to it in detail. Su Shi said on the side.

"You don't understand. Qin Chao said in a low voice, "Why do I say that it will take two hundred years for their Heavenly Domain Gate to prove this problem, because to prove this seventh question, there are a lot of involved, and many related arithmetic problems need to be proved, which is not done by people at all, and it is impossible to do it without writing mountains of paper manuscripts." ”

"Mountains of paper manuscripts?" Wang Anshi glared, and Cheng Yi, Sima Guang, Su Shi and others were also speechless.

Zu Riheng said in a deep voice: "I also agree with what Mr. Qin said, this question seems simple, but if you get in, you will find that there are many troubles." ”

"It seems that this seventh question Qin Gongzi really can't be solved. Cheng Yi sighed and looked at Zu Shengcai again, "Mingli, none of us can solve this seventh question, and you can also take out the eighth question for everyone to see." ”

"Yes. Zu Shengcai took out a piece of paper from his arms and handed it to Cheng Yi, who looked at it for a moment and frowned. "It's hard, it's hard. He handed the paper to Cheng Yang next to him, Cheng Yang also had a sad face after reading it, and handed it to Sima Guang, and then Wang Anshi and Qin Chao.

"Uh......" Qin Chao only glanced at the paper, and his heart swelled with strangeness, and he even handed the paper to Qin Ning next to him, Qin Ning swept his eyes twice, a smile appeared on the corner of his mouth, and handed the paper to Liu Qin, by Su Shi, Shao Bowen, and Lu Gong...... They all looked at the notes one by one, and their faces were embarrassed. Soon the paper was passed around in everyone's hands.

"Mr. Yichuan, how is it?" said Zu Shengcai in a loud voice.

Cheng Yi's eyes narrowed slightly: "This is not an arithmetic problem, but an unsolved mystery in natural science, what is needed in natural science is serious research and exploration in our martial arts world, if there is any gain, it will definitely be published in "Wulin Feng". ”

"If this topic is not a scientific research topic, why would we need a hundred years?" said Zu Shengcai. looked at Qin Chao again, "Gongzi Qin, what do you think about this question?"

"This is a chemistry question. Qin Chao smiled faintly, "I am far inferior to Duan Haifeng's son in chemistry." However, I have seen the explanation of this question at Duan Gongzi. ”

"Oh?" Zu Shengcai was stunned for a moment.

"Gongzi Qin, does Gongzi Duan really have an answer?" Zu Shengcai said in a deep voice.

"I think Duan Gongzi will publish a new book soon, so I won't talk about the answer to this question, so as not to make a noise. Qin Chao was silent, and he was helpless in his heart, the higher-level chemistry originally Qin Dynasty didn't want to throw it out so quickly, but Qin Ning was here, and there were many discoveries in chemistry, because Qin Ning, Xian Yuting, Bai Run'er and many other people helped Qin Dynasty do experiments. Naturally, he knows a lot of the inside story, and if Qin Chao doesn't say it, Qin Ning will also poke it out.

There was a discussion all around, and Zu Shengcai was slightly silent before he smiled, his smile was extremely stiff.

"I think everyone is also curious about question 9. Zu Shengcai's voice was loud, "Strictly speaking, this ninth question is also the one that our martial arts world has been thinking about and studying the most now. After Liu Qin's "Theory of the Movement of Heavenly Bodies", Duan Haifeng and Qin Xianao's "Dialogue", "Conversation", "Harmonious Celestial Bodies" and other books. We know a theorem. ”

"Everything in the world is either moving in a straight line at a uniform speed, or it is stationary. To change this motion requires an external force, which corresponds to the celestial system, and it is necessary to explain the phenomenon why the planets always move in a closed curve around the sun, rather than in a straight line to run into outer space. "Ancestral Shengcai said.

"Is that the problem?"

Cheng Yi's eyes burst out, and Sima Guang's back straightened. One by one, the spirit came.

Qin Chao's heart also pounded, Zu Shengcai's inquiry was the most critical doubt in astronomy, and Newton's thinking and answer to this question finally got gravitational pull.

"Clearly, on this issue we must first distinguish whether the forces of the celestial bodies are the same thing as in our lives. In what you say, you are unifying the phenomena of the celestial bodies with the phenomena of our lives. Cheng Yi spoke in a deep voice.

Zu Shengcai raised his eyebrows and laughed: "Mr. Yichuan, you have also read a lot of works by Duan Gongzi and Qin Gongzi, and they have said more than once in their books that natural phenomena are consistent, Qin Gongzi, do you say yes!"

"The essence of force should be the same. Qin Chao nodded slightly, "But what is in the celestial body that has an effect on these forces, we must figure it out." ”

"If the nature of the force is the same as that of heaven and earth, it is true that what we have to solve is not why the planets are constantly moving, nor why the planets do not move in a strict circular orbit. Sima Guang said in a deep voice.

Wang has thought about this question. Wang Anshi laughed, "We know the law of ejection, a thrown stone, draw a curve in the air to land, the harder the throw, the greater the initial velocity, the longer the arc length drawn in the air before the stone lands, we can assume that when we throw the power is getting bigger and bigger, bigger and bigger, the stone will fly longer and longer in the air, when our strength is large to a certain extent, the stone may fly out of the boundary of the earth, and fly in the air without touching the earth at all." ”

Everyone's eyes lit up.

"This Wang Anshi is really powerful. The Qin Dynasty also looked at Wang Anshi in surprise, Wang Anshi's reasoning was also Newton's idea when he first thought about the orbital motion of the planets, and it was because of this idea that later generations of rockets and satellites were launched into the sky.

"It is worthy of the famous Wang Jiefu. Zu Shengcai said loudly, "Although our Heavenly Domain Sect's thoughts on this issue are a little different from Mr. Wang's, I also feel that it is worth pondering after listening to Mr. Wang's statement. ”

"I don't know what you Heavenly Gate thinks. Wang Anshi looked at Zu Shengcai.

"Qin Gongzi has mentioned the consistency of nature many times, and we are very interested in this, so we have an idea, the stone falls from the sky, and the peach is ripe and falls to the ground, this kind of force that pulls the stone down from the sky and pulls the peach down from the tree will be the same force as the earth's power to control the moon?"

"Is it the same force?" Cheng Yi narrowed his eyes slightly, and Sima Guang's eyes shimmered.

Qin Dynasty's heart beat wildly again, Zu Shengcai's statement, in the later life, is Newton's apple landing, but the apple is replaced with a stone and a peach.

"Young Master Qin!" Zu Shengcai looked at the Qin Dynasty, "We think this is the case?"

"As I said earlier, the essence of force is the same. Qin Chao smiled slightly, "But what you said about the peach landing and the moon around the earth is the same force, there is no basis for words, what science wants is real proof." ”

"Qin Gongzi's words are very reasonable. Zu Shengcai laughed, "We have really made some proof here." ”

"How?" Qin Chao's face suddenly became serious.

"To understand the relationship between these two forces, we must first figure out what exactly causes gravity to decrease as the distance from the earth increases...... "Zu Shengcai said eloquently.

All around them fell into deep thought, only Qin Chao hung his head and looked at the desktop, his eyes shining like stars.

"This Heavenly Domain Gate, this Ancestral Saint is really powerful, and his train of thought is completely right. Qin Chao listened excitedly to Zu Shengcai's speech.

"If this one can be calculated, all our reasoning will be correct, but ......," Zu Shengcai's expression turned gloomy, "No matter how you calculate, it is not consistent with the actual observed data, and because of this, we have made this question the ninth question, as one of the hundred-year problems that our Heavenly Domain Gate will overcome." ”

"Young Master Qin. Zu Shengcai looked at the Qin Dynasty, with a hint of expectation in his eyes, "For this kind of thinking, because there are too many calculations in the end that cannot correspond to the upper and too many unsolved points, we are now a little at a loss, and there are internal disagreements, some think that we should go on according to this line of thought, and some think that we should change the way of thinking, Qin Gongzi is a rare wise man in the world, I don't know what to think?"

"My opinion......" Qin Chao hesitated slightly, if the answer to the last ninth question was to be given, it would be equivalent to throwing out Newton's "Mathematical Principles of Natural Philosophy", calculus, and gravity.

At this time-

"Needless to say. A crisp voice sounded, and I saw Qin Ning giggle, "Your thinking just now is completely correct, 100% correct." ”

Zu Shengcai looked at Qin Ning suspiciously, and his eyes also fell on Qin Ning.

"Why did Qin Niangzi make such remarks?"

"Of course, I peeked at my husband's draft. Qin Ning said indifferently.

"Oh? Qin Gongzi is also thinking like this?" Cheng Yi exclaimed, Wang Anshi and Sima Guang also looked at the Qin Dynasty, after the Qin Dynasty proposed the three laws of the planets, everyone looked forward to Duan Haifeng's comments, although Duan Haifeng gave the book "Harmonious Celestial Bodies" a very high evaluation, but also put forward the biggest flaw of "Harmonious Celestial Bodies", that is, the three major theorems of the planets in the book are inferred from the observed data, and cannot be inferred and proven.

For this reason, everyone has been thinking about the reasons behind the three major theorems of the planets, why the planets move like that, but there are too many unknown factors, and there are many ideas and ideas.

"Qin Niangzi, you just said ...... We're on the right track. Zu Shengcai noticed Qin Ning's tone, "And it's 100% correct, why do you think it's right to think so, is it because Qin Gongzi also thought like this?"

"Qin Niangzi, although Qin Gongzi is wise, he can't say that he is right when he thinks about it. Arkid spoke in a deep voice, "After all, when our Heavenly Domain Gate uses numbers to prove it, it is full of errors. ”

Qin Ning snorted in her nostrils, and then looked at Qin Chao with a smile: "Husband, you won't say this ninth question again, you can't do it, right?"

Qin Chao shrugged his shoulders, what else could he say at this time.

Qin Chao stood up, walked to the desk with the four treasures of the study, sharpened the ink, lifted the pen, moistened the ink, laid the paper, and put down the pen - the mathematical principles of natural philosophy, and a line of beautiful large characters appeared in the pen of the Qin Dynasty.
