Treasure Hunt all over the World

In the basement, Ye Tian took the ipad from Derek, and began to check how the homework given to Derek was done!

When he opened the floor plan of this basement, he immediately saw a lot of new numbers and abbreviations of many flowers and plants on this electronic drawing, filling the entire drawing.

After a quick glance at the blueprint, he immediately nodded in satisfaction and said:

"Nice job Derek, that's what I wanted"

As soon as the words fell, David couldn't wait to say:

"Steven, can you solve the mystery now? How do you solve the riddle left by Da Vinci? What secrets or treasures are hidden behind this riddle?"

Following David's words, everyone at the scene looked at Ye Tian and at the ipad in his hand, everyone's eyes were extremely hot!

"Okay, gentlemen, I'll tell you about it, but it's not necessarily accurate"

Ye Tian nodded in response, and then slid his finger to start operating on the ipad.

Immediately afterwards, he turned the ipad screen towards the crowd and started his own performance.

"The floor plan of the building that you see now is the structural drawing of the basement we are in. The scale of this historic building is quite large, and the scale of the basement is naturally the same.

Here, we found many granite pillars engraved with Fibonacci numbers, including Arabic numerals and various flowers and plants, arranged in a disorderly manner, seemingly without any rules to follow.

In fact, it is not the case. After some careful thinking, I have mastered the arrangement of these Fibonacci numbers. Next, I will ask Derek and the others to clearly mark all the Fibonacci numbers."

Before the words fell, there was a burst of exclamation at the scene.

"Wow! These Fibonacci numbers follow a pattern, why don't we see it at all?"

"These densely packed numbers and flowers and plants give people a headache just looking at them, let alone finding out the hidden rules between them, anyway, I can't do it!"

After a short pause, Ye Tian continued to say:

"At first I was like everyone else,

Looking at these densely packed Arabic numerals and patterns of flowers and plants gave me a headache. When I was thinking about these things at noon, my head was about to explode.

Fortunately, now is the Internet age, where you can find almost all the information and stories related to Da Vinci and almost all the relevant knowledge about the Fibonacci sequence on the Internet.

It was when I was inquiring about relevant knowledge and information that I suddenly came up with inspiration, which can be said to be a flash of inspiration, and combined with the floor plan of the basement, I finally solved this riddle.”

"clap clap"

There was a round of applause at the scene, and everyone was applauding for Ye Tian.

At the same time, there was a flash of admiration in everyone's eyes, and they gave a thumbs up secretly.

Of course, everyone was still a little skeptical, but they didn't show it.

After the applause fell, Ye Tian also got to the point.

"Leaving aside the buildings on the ground, let's take a look at the floor plan of the basement. It looks like a very neat rectangle with a base length of 55 meters and a width of 34 meters. It is exactly the two adjacent numbers in the Fibonacci sequence. .

According to the arrangement of the Fibonacci sequence, divide this rectangle into several squares until it reaches zero, and you will find a surprising discovery. We use 34 meters as the side length, and divide it from right to left and from bottom to top.

The first square drawn first has a side length of 34 meters, the second square has a side length of 21 meters, and the next ones are 13 meters, 8 meters, 5 meters, 3 meters, 2 meters, 1 meter, 1 A series of squares of meters.

As for the starting number of the Fibonacci sequence, 0, since it is 0, it means that there is no such square, it is a lost square, in fact, it is hidden in the last square with a side length of 1 meter .

We can call it the origin! After drawing these squares, everyone can see at a glance that these squares with different areas just fill the outside rectangle, that is, the basement.”

While saying these words, Ye Tian kept gesticulating on the ipad screen, dividing the floor plan of the basement into several squares with different areas.

These squares are all within the plan, they touch each other but never intersect, and they look very neat.

Hearing this, everyone at the scene nodded.

But due to the limited level of mathematics, most people are still at a loss, and only a few of them, their eyes suddenly lit up, as if they understood something!

However, they also half understood, and they didn't interrupt Ye Tian aloud to raise any objections.

As for Ye Tian, ​​he was still performing in high spirits.

"Based on the arrangement of the Fibonacci sequence, we divided the basement into several squares with different areas, and then looked at the Fibonacci numbers engraved on the stone pillars to find the rules.

Please look at the upper right corner of the square with a side length of 34 meters. There happens to be a stone pillar engraved with a pattern of a daisy. The daisy is a natural Fibonacci number, and its petals are exactly 34 petals.

Next, let's look at the lower left corner of this square, where there is also a granite pillar engraved with the Arabic numeral 21. In the Fibonacci sequence, the two numbers 21 and 35 are just adjacent.

Ignoring the other messy Fibonacci numbers for the time being, and connecting 35 and 21 with a clockwise arc, have we just drawn a 90-degree sector in a square with a side length of 34 meters?

Looking at the upper left corner of the second square, there is also a granite pillar standing here, with a rose pattern engraved on the top of the pillar. The rose is a natural Fibonacci number with 13 petals in total.

We connected 21 and 13 with an arc, and drew a fan with a 90-degree angle in the second square, and so on, and every subsequent square is the same.

In the end, it is a square with a side length of one meter. In this square, a 90-degree fan can also be drawn. Considering a square with zero area, a circle can be drawn here.

This circle is what I call the origin, which is the starting number 0 of the Fibonacci sequence. Starting from zero, along the arc we drew, we can see a complete Fibonacci sequence !

In fact, what we see now is the largest Fibonacci sequence in this basement, and there are many smaller Fibonacci sequences in this basement, which can be described as a ring.

These Fibonacci numbers finally point to the origin, that is, the center of the square with a side length of 1 meter! There are also a lot of messy Fibonacci numbers here, just to confuse people! "

"Wow! This is incredible!"

There was a burst of exclamation at the scene, everyone was completely stunned by Ye Tian's discovery and his wonderful performance, and they all looked dumbfounded!

After a while, those guys with better math background woke up first, and immediately cheered excitedly!

"My God! This is a Fibonacci spiral, and it actually exists in such a way. Today is really eye-opening!"

"Steven, you are amazing. How did you manage to discover the hidden Fibonacci sequence so deeply?"

With the burst of cheers, everyone else at the scene came to their senses.

At this moment, they looked at Ye Tian as if they were looking at an alien.

Ye Tian smiled softly, then joked and said:

"How did I do it? How did I discover this deeply hidden Fibonacci sequence? This is due to my education. As we all know, Chinese people have always been good at mathematics!"

"Wow! This is not only good, it is a math genius!"

"That's right! Among so many chaotic Arabic numerals and flowers and plants, it is impossible for me to accurately find out the hidden deep rules and draw the Fibonacci spiral! "

There was a burst of exclamation at the scene again, and everyone gave Ye Tian a thumbs up.

Ye Tian raised his hands and pressed down gently, motioning for everyone to be quiet, and then continued:

"That's right, the arc I drew is the Fibonacci spiral, that is, the golden spiral. The location of the origin is exactly the golden section point of this Renaissance-style historical building.

After basically confirming this point, I called Kenny and the others and asked them to make a three-dimensional digital model based on the floor plan of the basement to verify my conjecture.

As long as we put this floor plan full of Fibonacci numbers and flowers and plants into the model, we will see a very shocking scene of painting. You'd better keep your eyes open, the show has begun! "

As he said that, Ye Tian called up the 3D data model that Kenny and the others built on the iPad, and then pulled the basement floor plan full of Arabic numerals and flowers and plants into the model!

The next moment, everyone at the scene was instantly stunned.

What appeared on the screen of the ipad was circle after circle, layer upon layer of golden spirals, seemingly endless, spinning downward from the air and extending to the endless depths!

These golden spirals finally converged to the origin, which is the center of the one-meter-long square that Ye Tian drew before. There seemed to be a huge vortex, sucking all the golden spirals into it!

And in the middle of these golden spirals, there are countless Arabic numerals and English letters, as if they were kidnapped by those golden spirals, and they have been pulled into the depths of the vortex!

Looking at this scene, everyone at the scene felt dizzy for a while, and they were so shocked that they were all stunned on the spot!

At this moment, Ye Tianqing's clear voice suddenly came out, waking everyone up instantly!

"Gentlemen, we have solved the first layer of this riddle left by Leonardo da Vinci more than 500 years ago. I am sure that there must be a shocking secret or secret hidden deep underground at this golden section point." Treasure!"

Following his words, the scene immediately exploded!
