Everyone was in an uproar. Pi is a very simple value, only one decimal?

Is this playboy purely dreaming?

"How to prove it?" Others were not anxious, but this time Lilibai was anxious and glared at Zhang Jingtao fiercely.

Zhang Jingtao said proudly: "It is my Chinese character Zhang, character Zhang, and character Ya, which contain the secret of pi."

"Tell me," said Indra, obviously disbelieve it and sneered.

Of course Zhang Jingtao has to say it.

He took out a fan, tapped it gently in his hand, and said aloud: "I believe that what everyone is most interested in is the real value of pi. So, let me first talk about the real value of pi, pi, that is, the bow length, its real value is actually 3.2! And many people don't know how pi comes from. In fact, for Chinese people, this is just the ratio of straight lines turning into arcs, which comes from the bow family making the bow."

Yes, the bow length, which is called pi, is by no means an unstable number, but a very accurate 3.2!

However, it is difficult for people to accurately measure it, especially the ancients, because when measuring circles on the periphery of them, gap problems would arise.

Because the tape measure is actually rolled around the periphery of the circle, the rest of the measurement squares are also often deviated.

For this reason, if the 'pi' is used a little smaller, it can sometimes solve many problems, but undoubtedly, it will make the general technology accuracy extremely poor! This is why Chinese people who have lost their civilization in modern times can only use various gaps to supplement the 'pi' when developing manufacturing, so that the accuracy is not done well.

This value is also a fact, as long as there are good enough methods and tools to measure it.

However, there are obviously people who question this fact, but the person who questioned it first did not question its value, but someone surprised: "Pi is made from bows? How did you come?"

For this reason, Zhang Jingtao couldn't help but think of the scene of Ai making a bow in the prehistoric world.

I also thought of the word "one meter of sunshine".

He said: "Yes, make bows, but that is not an ordinary bow for archery. In the prehistoric world, my ancestor Zhang Guanyin, on the winter solstice, was on the nearby Taihu Xi Island in Gusu, which was at 32 degrees north latitude. He used a bamboo pole with a full meter of bamboo pole to observe the shadow of the sun. As a result, under the opportunity of the sun's angle of 32 degrees, she got a 1.6-meter-long shadow..."

Having said this, before we could continue, the people by the lake roared again, but then they became quiet.

You should know that pi represents civilized science and technology, but everyone in the Warring States Period, even all modern people in later generations, did not know that the pi truth value was 3.2. Zhang Jingtao said before that the character Zhang, the word "dividing" and "ye" all hide the mystery of pi. Then, China, which contains the secret of pi, is undoubtedly the only true civilization of mankind.

And the latitude of obtaining pi is the latitude of the origin of civilization!

As you can imagine, everyone obviously wanted to hear Zhang Jingtao continue.

Even Lilibai on the gimbal couldn't help but ask: "What's next?"

Zhang Jingtao thought of the bizarre cultural society in which everyone had to wear masks in later generations. He was almost worried about the fate of all mankind, so he was not afraid that the mystery of Pi would be known, so he said, "And then, in order to record this shadow, Empress Guanyin cut a 1.6-meter-6-meter-long bamboo piece. However, this time she did not make a bow with a rope, because it was only for watching movies. She only bent the bamboo piece according to her previous habit of watching the moon, fixed the bamboo piece with a 1-meter-long bamboo piece, and made it into a crescent shape, so that she could intuitively see the changes in the bow length representing the shadow. She also called this kind of bamboo piece like a crescent zither frame. As a result, do you know what Guanyin discovered in surprise?"

There was another rumbling sound until Yu Hanyan waved her hand to calm the surroundings and asked, "Did you find the right semicircle?"

Zhang Jingtao praised: "Not bad! A positive semicircle! For this reason, this is the short bow rate, that is, the semicircle rate, and this semicircle rate is 1 to 1.6."

After hearing this, everyone felt that the semicircular theory was extremely real and people couldn't help but feel that it was true.

Guo Yun said, "Wait! Two pieces of bamboo can also be considered a bow? No, right?"

Zhang Jingtao thought of the word "口" that is difficult to untie without civilization, and smiled and said, "Of course, for the Empress Guanyin, it is not only a bow that can be used for archery with a rope. The two bamboo slices together are also called bows, which are also very useful, and even have the meaning of circle. For example, when used in construction, the word "口" in the word "口" contains the word "口" and represents the dome, that is, the bow can be a perfect circle; for example, the weak character "口" and the composition of double bows clearly means that a set of bamboo slices that are flexible enough to be pulled into a perfect circle, and the stretching degree can be increased or decreased by others. The bamboo slices that are allowed to be used by others are weak, that is, weak, originally said that the bow strength is weak; for the word "口" means that the meaning of stewing rice in artificial circular instruments such as double bows is used to use the circumference of the '口' sound."

Guo Yun was speechless and knew that this was true as soon as he heard it. This was the only civilization's power, and Chinese characters were all related.

Wei Yuanzi didn't think this could be argued, and just said, "This is indisputable, what about afterwards?"

Zhang Jingtao did not keep it a secret and said, "After that, the Empress Guanyin of course discovered that two semicircular short bows could be combined into a perfect circle, just like the trend of the moon, which contains the left and right double semi-forms. For this reason, the word "Yehovah" is the word "Yehovah". This word "Ye" represents: double ear shape, double bow shape, double moon shape, and night sound."

Everyone suddenly realized, Luo Lei happily continued: "So, two 1.6s become pi of 3.2?"

Zhang Jingtao said: "Yes, but this pi has a name called 'bow length'. That is to say, pi is the ratio of the arc length of the bow arm to the bow string. In particular, if a bow fixed to 1 meter is fixed, it can be regarded as a short bow, but if two 1.6-meter bamboo pieces are combined together to form a bow that can be pulled apart and restored to 1 meter 6, it is considered a long bow, and the long bow can be pulled into a perfect circle. For this reason, this is another meaning of bow length. The Zhang surname used by Guanyin for himself was created, which is to say, the person who created the bow and arrow and invented the pi."

Of course, the word Zhang has other meanings, but Zhang Jingtao did not say it.

Guo Yun didn't believe it and said, "No way? Pi will also be called bow length? Isn't it more intuitive to call it pi?"

Zhang Jingtao said: "Intuitive? Haven't you ever thought that pi is not only used to calculate the circumference, but also to calculate the area of ​​the circle. And is the real pi and the area of ​​the circle actually different? Therefore, the method Guanyin called it: bow length, that is, Zhang rate, because of the method he obtained."

After hearing this, Wei Yuanzi also questioned and said, "What? I have never heard of the difference between the area ratio and the pi. What a joke! Do you guys say so?"
