: 79 One Akka Math Problem

"Why, here is another black megalith that is different from other rocks." Soon, someone discovered the stele.
Wu Xiang walked over the stone monument and saw the patterns and words carved by the Akka people on the stone monument. "Let ’s take a look, there is a big stele here, with patterns and text carved on it."
Suddenly, a group of people hurrah ran to the stone monument.
The stone stele is very large, more than ten meters long and more than four meters high.
The first thing you see in the stele is a pattern.
A pattern consisting of matches and sticks made of dots and lines, a pattern consisting of more than a dozen concentric circles like a target in a shooting range
"These symbols are, ..." Many people at first did not see what these patterns meant.
After a few minutes.
"This is the astrological chart of the solar system." Suddenly, a person in the crowd exclaimed, "Look at the pattern like a match stick, not like a goddess with harvesting wings, holding it in one hand. With a bunch of wheat ears and a sickle in one hand, this is a Virgo constellation, and it can't be wrong. There are more than a dozen concentric circles like a target pattern. This is the solar system astrological chart. "
With a reminder from others, I took the seat right, and everyone soon saw what the two carved patterns represent.
"I see, this earth." A tourist said loudly, pointing at a concentric circle in a range-like target pattern composed of more than a dozen concentric circles.
"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 star map of the solar system so accurately by observing astronomical phenomena long, long ago."
Uh ...
"Let's come and see."
Somebody soon found it again.
"There is also a carved picture here, it seems to be some text."
"This is not a word, it's an Akka number." An old expert, wearing a pair of glasses, six or seventy years old, walked around, looked at the patterns carefully for a few minutes, and then said, "This symbol It consists of two simple strokes, one horizontal and one vertical.
Everyone who has studied computer knows that there are binary numbers in computer languages. The symbols here are the same as the computing principles of computer binary numbers. One horizontal represents 1 and one vertical represents 0. In theory, one consisting of one horizontal and one vertical The string symbol can represent any number, and any number can also be calculated through operations. "
原来 "That's the case, that is to say, Akka people long ago can be proficient in using these simple symbolic arithmetic."
"Yes, the theory is this. Translate the above series of symbols horizontally and vertically into computer binary numbers of 1 and 0, 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 splendid civilization has no written records in the world's archeological research and history."
Uh ...
Many people took out paper and pens, opened the calculator that came with their mobile phones, and according to the interpretation method just explained by the old professor, a string of horizontal and vertical strokes on the stone tablet was first translated into binary numbers. This is very simple and can be done by elementary school students.
Then from computer binary numbers to decimal numbers, this step has stumped many people, no one who has not studied computer languages ​​will not translate.
Finally, it is very simple to calculate using modern mathematical operation methods.
Everyone is quiet, only to hear the sound of the pen tip across the paper ‘唰 唰’ like a silkworm eating mulberry leaves, and the sound of the mobile phone ’s key ‘嘀嘀’.
Twenty minutes later, someone first figured it out. He 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 Chinese are good at mathematics, which seems to be a universally recognized fact. There was such a thing. As one of the Sino-British exchange programs, more than 60 mathematics teachers in Dinghai went to England to help improve the mathematics level of middle school students in the region. In the UK, more than 60 math teachers will also be sent to Dinghai Normal University for long-term studies to improve mathematics teaching.
"What!" A very shocked expression on the face of a British professor exclaimed, "365.2424, you sure!"
Chinese tourists said very decisively, "I'm sure, is there anything wrong? Should I count it again and show it to you in minutes?"
"Mayer, don't forget, it's actually 365.2424, I figured it out," said the companion of the British professor Mayr, with an incredible expression on his face as well.
Many people figured it out next, 365.2424.
The calculation result of 365.2424 came out.
Many people were shocked at the scene, stunned, and opened their mouths wide.
的 Anyone who knows a little bit about astronomy knows what this data is.
The ignorant person looked at the shocked expression on the face of the companion beside him. They looked puzzled.
"Is there anything wrong? Isn't it a series of math problems of the Akka people? Anything so shocking, such a big reaction, it's an exaggeration."
Ignorance is blessing.
Immediately, a young college student couldn't stand it anymore, stood up and explained, "365.2424, don't you see anything special about this number ~ EbookFREE.me ~ 365 days a year."
"Forget it, I do n’t know how to tell you so esoteric. Let me tell you a little bit." The young college student was completely defeated by him. "We all know that 365 days a year, this is the Earth that goes around the sun once a week. Developed by time.
Actually 365 days is a round number. The exact number should be 365.2422 days. Then 365 days a year is 0.2422 days away from the actual year. In this way, four years later, there is almost one day less than the actual year. In order to make up for this difference, the calendar stipulates that 4 years is set to be a year, that is, the year divisible by 4 is a leap year. It is additionally stipulated that, in the case of a century, it must be divisible by 400 to count as a leap year. Do you understand now? 365.2424 is the time that the Akka people calculated that the earth circled the sun. "
5.2365.2422, 365.2424, you mean that the time that the Akka people measured the earth's orbit around the sun 365.2424 thousands of years ago and the modern measurement time 365.2422 are only 0.0002 days apart.
"Correct."
