From the Island Owner to the King

The stele is very large, 7 or 8 meters long and more than 3 meters high.

Chen Ruijie said, "This is a stone tablet placed on top of the Akka Pyramid."

"Are the pyramids the same as the pyramids in Egypt?" Someone asked Chen Rui.

"There are some differences with the pyramids in Egypt. In appearance, the Akka Pyramid is flat-topped, the tower is square, the bottom is large and the top is small, and the layers are stacked. Moreover, the Egyptian pyramids buried the pharaohs, and the function of this pyramid is different. However, one thing is the same, it is also ancient and grand, and it is also a miracle in the history of architecture." Chen Rui said with a smile.

Everyone walked over to the stone tablet and saw the patterns and words carved and painted on the stone tablet by the Akka people.

"Everyone, come and see, there are patterns and words carved on the stone tablet."

Suddenly, a group of people hula la and quickly walked to the stone monument.

The first thing you see on the stele is a pattern.

A pattern of dots and lines like a matchstick, a pattern of a dozen concentric circles like a target in a shooting range

"These symbols are..." Many people didn't see what these patterns meant at first.

After a few minutes.

"This is the astrological chart of the solar system." Suddenly, someone in the crowd exclaimed, "Look, everyone, the pattern is like a combination of matchsticks, doesn't it look like a goddess with wings who is harvesting, holding in one hand With a bunch of wheat ears and a scythe in one hand, this is the constellation Virgo, absolutely can’t go wrong. There are also a dozen concentric circles that look like a target. This is the solar system astrological map.”

With the reminder of others, they took their seats, and soon everyone could see what the two carved patterns represented.

"I understand, this earth." A tourist pointed to a concentric circle in the pattern of a dozen concentric circles like a shooting range target and said loudly.

"This is Mars."

"This is Venus."

Everyone pointed at the concentric circles on the target and said excitedly.

"Unbelievable."

"Yeah, it's incredible. This Akka civilization has been able to draw the solar system star map so accurately by observing celestial phenomena a long time ago."

......

"Everyone come and see."

Soon someone found out.

"There is also a carving here, which seems to be some text."

"These are not words, but the numbers of the Akha people." An expert in his 60s and 70s who wore glasses walked by, carefully observed the patterns for a few minutes, and then said, "This string of symbols It is composed of two simple strokes, one horizontal and one vertical.

Anyone who has studied computer knows that there are binary numbers in computer language. The symbols here are the same as the operation principle of computer binary numbers. A horizontal represents 1, and a vertical represents 0. String symbols can represent any number, and any number can also be calculated through operations. "

"It turns out that, that is to say, the Akka people have been able to use these simple symbolic arithmetic proficiently a long time ago."

"Yes, the theory is like this, translate the horizontal and vertical symbols in the above string into computer binary numbers of 1 and 0 respectively, and then translate the computer binary numbers into decimal numbers in our mathematics,

In this way, the operation is very simple. "

After listening to the old professor's explanation, everyone understood and said with emotion, "This Akka civilization has given us too many incredible things."

"Yeah, it's hard to imagine that such a brilliant civilization has no written records in the world's archaeological research and history."

......

Many people took out paper and pens, turned on the calculators that came with their mobile phones, and translated a string of digital symbols on the stone tablet consisting of horizontal and vertical strokes into binary numbers according to the interpretation method just described by the old professor. It's so simple that even elementary school students can do it.

Then, the computer binary numbers are translated into decimal numbers. This step has stumped many people, and people who have not learned computer languages ​​will not be able to translate.

Finally, it is very simple to use the operation method of modern mathematics to calculate.

Everyone was quiet, and only heard the sound of the tip of the pen swiping across the paper, like a silkworm eating mulberry leaves, and the sound of a button on the phone.

After more than ten minutes, someone first figured it out. It was a very young Chinese tourist. He waved the paper in his hand and said proudly, "I figured it out, it's 365.2424."

The fact that Chinese people are good at mathematics seems to be a fact recognized by the world. There was such a thing. As one of the Sino-British exchange programs, as many as 60 mathematics teachers in Dinghai went to England to help improve the mathematics level of middle school students in the region. The United Kingdom will also send more than 60 mathematics teachers to Dinghai Normal University for long-term study in order to improve the level of mathematics teaching.

"What!" A British professor exclaimed with a very shocked expression on his face, "365.2424, you are sure!"

The Chinese tourist said very confidently, "I'm pretty sure, what's wrong? Do you want me to do the math again for you to see and figure it out in minutes."

"Meier, don't forget it, it is indeed 365.2424, and I figured it out," said British professor Meier's companion, with an incredible expression on his face.

Then many people figured it out, 365.2424.

As soon as the calculation result of 365.2424 comes out.

Many people present were shocked, stunned, and their mouths opened wide.

Anyone with a little knowledge of astronomy knows what this data is.

The person who didn't understand looked at his companion next to him with a shocked expression on his face. They looked puzzled.

"Is there anything wrong? Isn't it just a series of math problems from the Akka people? What's so shocking, such a big reaction is too exaggerated."

Ignorance is a blessing.

Immediately, a young college student couldn't stand it anymore, and stood up and explained, "365.2424, don't you see anything special about this number?"

"365, 365 days a year."

"Forget it, you don't understand how profound it is, let me tell you something simple." The young college student was completely defeated by him, "We all know that there are 365 days in a year, and this is according to the fact that the earth revolves around the sun once. time made.

In fact, 365 days is an approximation, and the exact number should be 365.2422 days, then a year of 365 days is 0.2422 days away from the actual year, so after four years, it is nearly one day less than the actual year. In order to make up for this difference, the calendar stipulates that a leap year is set in 4 years, that is, a year that is divisible by 4 is a leap year. In addition, it is stipulated that when a century year is encountered, it must be divisible by 400 to be a leap year. Do you understand now? 365.2424 is the time taken by the Akha to make one revolution around the sun. "

365.2422, 365.2424, you are saying that the time 365.2424 when the earth circles the sun as measured by the Akka people thousands of years ago is only 0.0002 days away from the time measured in modern times 365.2422.

"right."
