Chen Rui said, "This is a stone monument placed on the pyramid of Aka."

"Pyramid, is it the same as the pyramid of Egypt?" Someone asked Chen Rui.

"There is a difference between the pyramids of Egypt and the pyramids of the Aka. The pyramids of Egypt are square, the towers are square, the tops are small and the layers are stacked. Moreover, the pyramids of Egypt are for buried the Pharaohs. The role of this pyramid is different. However, one thing is the same, it is also a long time ago, the scale is huge, and it is also a miracle in the history of architecture." Chen Rui smiled and said.

Everyone walked over to the stone tablet and saw the patterns and texts carved by the Aka people on the stone tablets.

"Everyone is coming to see that there are patterns and words on the stone tablet."

Suddenly, a group of people walked hurriedly to the stone monument.

The first thing you see on the stone tablet is a pattern.

A pattern consisting of a number of dots and lines, like a matchstick, a pattern of more than a dozen concentric circles like a target.

"These symbols are..." Many people just started to comprehend what these patterns mean.

After a few minutes.

"This is the star phase diagram of the solar system." Suddenly, one of the crowds shouted loudly. "Look, like a matchstick, the same pattern, like a G.o.ddess with two wings being harvested, in one hand. Holding a bunch of wheat ears, holding a sickle in one hand, this is a maiden constellation, absolutely not wrong. There are more than a dozen concentric circles like a target pattern. This is the solar system star map."

With the reminder of others, everyone can see that the two carved patterns represent what they mean.

"I understand, this is earth." One visitor pointed out a concentric circle in a target-like target pattern consisting of more than a dozen concentric circles.

"This is Mars."

"This is Venus."

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

"Incredible."

"Yes, ah, ah it is simply inconceivable that the Aka civilization in a long, long time ago, by astronomical observation, it has been able to so accurately depicts the solar system like a star map."

"We came to see "

Soon someone found it again ."

"There is also a carved picture here, it seems to be some words."

"This is not a word, it is the number of Aka people." There are a gla.s.ses, sixty or seventy-year-old old experts have gone, look carefully at these patterns and observed it for a few minutes, and then he said, "This string of symbols consists of two simple strokes, one horizontal and one vertical. Those who have learned computers know that there are binary numbers in computer languages, the symbols here are related to computer binary numbers. the operation principle is the same, a vertical represents 1, horizontal represents 0, in theory, a cross-p.r.i.c.ked by a string of symbols consisting of any number may represent, same can also be calculated by calculation any number."

"So That is to say, Aka people a long time ago can already use these simple symbolic calculations skillfully."

"Yes, the theory is like this, and the above-mentioned string symbols are translated into 1 and 0 respectively. Computer binary number, then translate the computer binary number into a decimal number in our math, In this way, the operation is very simple. "

After listening to the old professor doubled to explain, they all understand, and someone said with emotion," This Aka civilization has given us a lot of amazing discoveries."

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

A lot of people took out pen and paper, open the phone comes with a calculator, according to interpretations to the old Professor just mentioned, the string on the stone from the horizontal, two vertical strokes up the numbers the symbol is first translated into a binary number, which is very simple, can be done by the primary school students. Then the computer binary number is translated into a decimal number. This step has stumped many people, and those who have not studied computer language will not translate it.

Finally, the use of modern mathematical calculation method to calculate, very simple.

Everybody quiet down, only to hear the pen across the paper 'swish' sound like silkworms eat mulberry leaves and the phone keypad sound.

Dozen Minutes later, someone first calculated it. It was a very young Chinese tourist. He waved his paper and said with pride. "I figured it out, it is 365.2424."

Chinese mathematics is good. It seems to be a universally recognized fact. There used to be such a thing. As one of the Sino-British exchange programs, there are more than 60 mathematics teachers in Dinghai City going to England to help improve the mathematics of middle school students in the region. The United Kingdom will also send more than 60 mathematics teachers to Dinghai Normal University for a long-term study to improve the level of mathematics teaching.

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

Chinese tourists are very determined. "I am sure, what is wrong? Do you want me to count it again for you, and I can calculate it in minutes."

"Meyer, it's really 365.2424, I figured it out." "The English professor Meyer companion said that his face also showed an incredible expression.

Many people have figured it out, 365.2424.

The calculation result of 365.2424 comes out.

Many people were shocked at the scene, stunned and their mouths wide open.

Anyone who knows a little bit of astronomical knowledge knows what this data is.

The unintelligible person looked at the face of his companion with a look of shock. They showed a puzzled expression.

"Is there something wrong? Isn't it a series of math problems for the Aka people? What is so shocking, so big reaction, too exaggerated."

Ignorance is a blessing.

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

"365, 365 days a year."

" Forget it, tell you so esoteric, you don't understand, tell you something simple." The young college student was completely defeated by him. "We all know that 365 days a year, this is the time around the earth orbiting the sun time.

In fact, 365 days a divisor, the accurate figure should be 365.2422 days, then 365 days a year on the actual year, a difference of 0.2422 days, so after four years a drop of nearly one day longer than the actual year. in order to to make up for this difference, the calendar stipulates that a year is set for four years, that is, the year that can be divisible by four is a leap year. In addition, in the case of the century, it is inevitable that it will be divided by 400. It is now a leap year. Now understand? 365.2424 Aka calculation of the Earth around the sun."

"365.2422,365.2424, you say, Aka people ten thousands of years ago estimated the time of the Earth orbiting around the sun 365.2424 and with 365.2422 modern measuring time, it's only a difference of 0.0002 days.

"Yes."
