Zu Chongzhi's lifelong dream is to let everyone in the world learn the method of arithmetic like him, and Liu Yuetian's request is tantamount to fulfilling his dream.

"Okay, then you can stay!"

The best way to deal with an unruly genius is to directly crush the past in the opponent's strengths, and now Zu Chongzhi's attitude towards Liu Yuetian is more respectful than that of his own father, and the stone slab written by Liu Yuetian was also regarded as a treasure by him, and he moved it to his room by himself.

"Lord Wang, the villain will go back, if this third son offends you......... How ...... you are Bear some shoulders. ”

"Brother Wang, when you go back, tell Mrs. Zu to ask him to rest assured, and when he sees Brother Zu again, he will definitely be impressed."

Wang Bao was still a little worried when he came, but when he left, he saw that the third son, who even had nothing to do with his father, was respectful in front of Liu Yuetian, more honest than a kitten and a puppy, and couldn't help but sigh in his heart: No wonder this prince beat Liu Yuan, who has lived in Tianshui for many years, at a young age, his ability is simply unfathomable, and this information must be reported to Taishou truthfully after he goes back.

To be able to study pi in this era when scientific research is almost desert, there is no doubt that Zu Chongzhi has the potential to be a mathematician.

The system's evaluation of Zu Chongzhi is also a historical-level celebrity, he is not a military general, and he has no potential to become a famous minister, but his charm and intelligence have reached sixty and seventy-two respectively, especially in terms of intelligence, more than twice that of ordinary people, and this level of intelligence is not too much to call it a demon.

The material basis of this world is the same as that of Liu Yuetian's previous life, which shows that mathematics and physics are exactly the same.

And Liu Yuetian has in his mind the scientific and technological knowledge of human beings from the primitive Stone Age, the Bronze Age, the Iron Age, the Steam Age, the Electric Age, the Nuclear Energy Age and the Primary Interstellar Age, especially mathematics and physics.

So theoretically speaking, Liu Yuetian can turn Zu Chongzhi, who only understands pi, into a mathematician who has mastered esoteric number theory, but Liu Yuetian has new ideas after reading Zu Chongzhi's research in other aspects.

This time, Zu Chongzhi went to Tianshui and brought some "inventions", such as a star meter to measure the stars, as well as the almanac he compiled, although it was very simple in Liu Yuetian's eyes, but in the context of this era, it was already very difficult, which showed that he was not a pure mathematician, and he also had the talent to become an experimental physicist.

This is not surprising, mathematics and physics have a lot of similarities, and even some aspects belong to the same discipline, but physics has a little advantage, that is, it is particularly experimental, even no less than some inventors, Liu Yuetian needs this kind of person with strong hands-on ability, and now it seems that Zu Chongzhi is such a genius.

Liu Yuetian wants to turn Zu Chongzhi into the greatest inventor of this era.

Again, the era you live in determines your vision, even if it is a genius like Zu Chongzhi who has a strong desire to explore, such as the idea that the sky is round and the place is round, such as the fact that everything is created by gods, etc., but in the next two days, Zu Chongzhi's worldview has been completely subverted.

The world inhabited by humans is a huge sphere, and the dazzling sun in the sky is called a star, and the stars in the night sky are all stars like the sun, but because they are so far away, even the fastest horses can run in the direction of the stars for billions of years or more.

Zu Chongzhi naturally didn't believe it at the beginning when he heard this, but in Liu Yuetian, he didn't just talk about it, he had all kinds of data to support it.

For example, the almanac compiled by Zu Chongzhi recorded the shadow position of the sun at many times of the year, and through these data, Liu Yuetian easily came to the conclusion that the earth was round, so that Zu Chongzhi could not refute it at all.

Then, based on the conclusion that the Earth is round, the time of appearance and the position of several planets around the Earth, such as Jupiter, are deduced, and the results obtained are exactly the same as those observed and recorded by humans for hundreds of years.

This is all true, even if Zu Chongzhi didn't dare to believe it, but in the end he still believed it, a real scientist is like this, there is only the word truth in his heart, if he is replaced by someone else, or he simply believes in his own master like Xiaoluozi; Either that, they sneer at them with heresies and crooked ways.

Since then, an endlessly magnificent and mysterious world has been revealed in front of Zu Chongzhi, and the next step is that Liu Yuetian will lead him to continue to explore deeply.

"If the net external force of an object is zero, then the object either remains at rest or moves in a straight line at a uniform speed, which is the law of motion in nature.........

Liu Yuetian is teaching Zu Chongzhi the three laws of motion in nature, I have to say that after Zu Chongzhi's worldview is completely transformed, the speed of acceptance of Liu Yuetian's knowledge began to be greatly accelerated, you must know that even Liu Yuetian's previous life, it took nearly a thousand years to cross from the ancient era of ignorance to the era of summarizing the laws of motion in nature, and Zu Chongzhi only took a short five or six days, but this does not make Zu Chongzhi feel how jumpy, science is like this, the laws of nature are eternal, Human beings only need to discover, this is a very slow process, and it needs to achieve breakthroughs at several important nodes, even these nodes are the result of accumulation, and there is no problem in Liu Yuetian's eyes.

"That......... Teacher, you said this stone, why does it fall when I let go of my hand? What forces is it pulled by? ”

Zu Chongzhi picked up a stone and let go of his hand, and the stone immediately fell to the ground.

"Okay, you really have a deep understanding of the movement of objects, let me tell you, this stone is because of gravity, which involves the theory of gravity of all things, that is, everything in the world, as long as there are objects will emit gravity to attract other objects, the key is the size of the mass, and this stone is the gravitational pull of the earth before falling to the ground, just like this tide, why is there a tide in the sea? Because of the attraction of the moon and the sun, the greater the power of each full moon, the greater the tides generated. ”

"Oh, I see, I see!"

Zu Chongzhi nodded frequently.

"When you let go, the force on the stone is the downward force of gravity and the resistance of the air to it, but the gravity is greater than the resistance it is subjected to, and the resistance is the same, so it will start to fall at a uniform acceleration, and this formula is its velocity expression."

Liu Yuetian wrote a string of formulas on the slate.

"This is the final velocity, this is the initial velocity, and this is the acceleration exerted by the earth on the object, the acceleration is constant, the initial velocity is zero, then with the change of time, with each additional second, its final velocity increases."

"Final velocity, initial velocity, acceleration, I'm going to write down .........!"

Zu Chongzhi recorded what Liu Yuetian said on the bamboo slips, and the formulas written by Liu Yuetian on the stone slab were also written down word for word.

Zu Chongzhi is now hungry, many new nouns he has heard of for the first time, or it is the first time in this world, but these nouns are not jerky, on the contrary, each word can accurately express a phenomenon in the physical world, so that Zu Chongzhi has a feeling of sudden enlightenment.
