The Tubo envoy stood up and asked loudly: "King of Shu, you are known as the most talented man in the Tang Dynasty. You left many popular poems and created countless miracles. I have a problem that I want to ask the King of Shu.
I wonder if the King of Shu can help me clear up my doubts?"
Li Min smiled slightly and said, "If you have any problems, just ask them!"
The Tubo envoy couldn't help but said: "May I ask the King of Shu, how far is the moon from us and what is the distance?"
Hearing this question, Li Min was slightly surprised and couldn't help but look at the Tibetan envoy.
This question was really beyond Li Min's expectation.
In Li Min's expectation, the so-called difficult problems that envoys from these countries could come up with.
It's nothing more than a few ancient mathematical problems, or couplets, riddles, poems, songs, etc.
And this Tubo envoy actually asked such a technical question, which made Li Min look at him with admiration.
Li Min couldn't help but smile, and then asked: "Then do you know the answer?"
The Tubo envoy exaggeratedly said: "King of Shu, this is a question we are asking you for. If we know how to do it, do we still need to ask you for advice? Is it because the King of Shu cannot answer this question at all?"
The question raised by Tubo was quickly passed on to the people watching the excitement.
After hearing this question, the people of Yizhou were all worried about the King of Shu.
I have to say that this Tubo envoy is really bad!
I'm afraid even he himself doesn't know the answer to this question, right?
What the hell is going on here?
This question asks how far away the moon is from us and what is its distance?
The next question is how far is the sun from us and what is the distance?
Next, I ask the Cowherd and the Vega: Isn’t this just a rogue thing?
At this time, the King of Shu smiled and replied: "The question is, if you don't know the answer, then if I just randomly say a number, wouldn't it be difficult for you to distinguish the authenticity?"
King Shu's answer immediately caused a round of applause from around him.
That's right, since you're asking such a stupid question, it's a question that has no answer at all.
Of course we can also play rogue!
At this time, the people watching could not help but praise Li Min's wit!
After hearing Li Min's words, the Tubo envoy laughed and said: "How can the king of Shu, who is famous all over the world, be a person who is so famous? What's more, although I don't know how to calculate this distance, but by coincidence
Yes, someone really asked for it, and I have the answer here! If the King of Shu talks nonsense, I'm afraid it won't work!"
What?
This Tibetan envoy actually knows the answer?
How could he be so bad?
At this time, the people around him began to worry about King Shu.
In fact, there are many tourists visiting Yizhou now.
There are many wise men among these audiences, but even they don't have the slightest clue about this topic.
How far are we from the moon?
I have no clue about this, how can I calculate it?
Among the crowd, a girl covered with gauze looked at the King of Shu with interest.
This girl is naturally Cui Shiniang.
And this question was actually posed by her.
Cui Shiniang is very interested in astronomy.
In her spare time, Cui Shiniang once calculated the astronomical calendar herself.
He even used his own method to calculate the distance between the moon and the ground.
In fact, if you delve into ancient Jiuzhang arithmetic and other algorithms, there are still ways to calculate the distance from the earth to the moon.
Li Min did not expect that in this era, someone would really be able to calculate it.
Li Min smiled slightly and said: "If you want to calculate the distance from the ground to the moon, you can use the relationship between the sides and angles of a triangle to solve the problem."
When Li Min said these words, Li Min noticed that the expression of the Tibetan envoy changed slightly.
This made Li Min feel more and more that this guy really knew how to calculate the distance from the earth to the moon.
And, he also used this method.
Therefore, Li Min continued: "Of course, it must be an isosceles triangle, so it is very important to find the key position. This midpoint position is the place closest to the moon. Then look far enough to both sides to form an isosceles triangle.
The distance is limited to thousands of miles. Then based on the angle between the moonlight and the ground, and the distance from the ground, we can calculate the distance between the ground and the moon."
Can this method be used to find the distance from the earth to the moon?
Well, in theory, it's definitely possible.
But in reality, the error will be very large.
First of all, it is a thousand miles long. You must first make sure that the two points you are looking for are on the same straight line, which is a very difficult thing.
Secondly, the included angle is not easy to measure.
There is also the issue of the center point. This center point should preferably be at the equator, otherwise, it is basically unlikely to be an isosceles triangle.
Wait, wait, etc. In short, the error here will definitely be huge.
After Li Min finished speaking, the Tubo envoy looked at Li Min stupidly, stunned, with an expression of disbelief.
It seems that Li Min is indeed right, that is the method.
Li Min smiled again and said: "The moon is about 768,000 miles away from the ground. I wonder if this value is correct?"
"this……"
The Tibetan envoy's face once again showed an expression of extreme shock.
Well, actually, there is a big gap between the number on his paper and the number mentioned by King Shu.
But this number is also within the range of 700,000 miles.
In other words, the two people may have different results due to different measurement methods.
But there is absolutely nothing wrong with the method they use.
Moreover, the Tubo envoy did not dare to say that the King of Shu had made a miscalculation.
Maybe the person who gave him this question made a miscalculation?
Therefore, the Tubo envoy had no choice but to say: "Yes, this answer is correct! I admire the King of Shu for his knowledge of heaven and man!"
Seeing this scene, the audience below suddenly burst into applause.
Their King of Shu is really powerful!
For such a difficult problem, they don't even have the slightest idea of how to solve it.
But King Shu found the solution easily and gave the answer smoothly.
The King of Shu is really awesome!
Seeing that the Tibetan envoys were defeated so quickly, the envoys from other countries didn't look very good either.
This question asked by the Tibetan envoys was extremely difficult, and they thought they did not know how to solve it.
But King Shu gave the answer easily.
So, I’m afraid their problems won’t trouble the King of Shu, right?
At this time, the second messenger finally stood up.
This one is Pi Xiake, the envoy of Pishan Kingdom, and Pi Xiake actually brought out a monkey.
"This monkey is the smartest monkey in our Pishan Kingdom. He can count and even add. May I ask, do you have such smart animals in the Tang Dynasty?"
For some reason, after Pi Xiake said these words, he suddenly felt smiles on the faces of the audience around him.
