Calculate!
What's this?
This is the crystallization of the Chinese nation's entire culture with a long history and high wisdom in mathematics!
It needs to be mentioned separately here.
Some people ask, why did Liu Zheng travel back in time for so long and didn’t even make Arabic numerals? How dare he make a database?
Very simple.
In fact, in a historical sense, in terms of accuracy, and in terms of the advancement of algorithms, calculations in Chinese history are no worse than Arabic numerals! Because of China’s calculations, the decimal system was implemented thousands of years ago!
The ancient Chinese decimal system of calculation and notation was a great creation in the history of world mathematics. Comparing it with the notation systems of other ancient peoples in the world, its superiority is obvious. The ancient Roman numeral system did not have a place value system and only had seven basic symbols. It was quite difficult to memorize larger numbers. Although the Mayans of ancient America knew the place value system, they used base 20; the ancient Babylonians also knew the place value system, but they used base 60. Carrying 20 requires at least 19 digits, and carrying 60 requires 59 digits, which makes counting and operations very complicated. It is far less simple and convenient than the decimal system, which can represent any natural number with only 9 digits. The many outstanding achievements of ancient Chinese mathematics in calculations should be attributed, to a certain extent, to this calculation and notation method that conforms to the decimal system. Marx in his book "Mathematical Manuscripts" called the decimal notation "one of the most wonderful inventions", and of course it was not an exaggeration at all.
In the arithmetic counting method, the number of units is expressed in two ways: vertical and horizontal. Among them, 1-5 are represented by the corresponding number of arithmetic chips arranged vertically and horizontally. 6-9 are represented by the above arithmetic chips plus the corresponding ones below. To express the calculation. When expressing multiple digits, use the vertical format for the ones digit, the horizontal format for the tens digit, the vertical format for the hundreds digit, and the horizontal format for the thousands digit, and so on. If it encounters zero, leave it blank. This counting method follows the decimal system. The age of the appearance of calculation is unknown, but according to historical data, it is speculated that calculation appeared in the late Spring and Autumn Period and the beginning of the Warring States Period (722 BC ~ 221 BC) at the latest.
It is amazing that our ancestors understood such sophisticated calculations more than two thousand years ago! In this, arithmetic plays an indispensable role. It was originally created in China before the abacus was invented and is the most effective calculation tool. The early development and continued development of ancient Chinese mathematics all benefited from calculation.
And what is the significance of the appearance of Arabic numerals?
In fact, just like the calculation, they only implemented the decimal system!
However, it is undeniable that the creation of the number "0" by the Alaba number has changed the academic landscape of mathematics.
The invention of "0" perfected the decimal system.
Another advantage is that Araba numbers are relatively simple to write.
But Liu Zheng thinks...
China's calculations, at least in this era, are still advanced in the field of mathematics in the world.
Numbers are just like words. If you want to overthrow them and adopt another one, many political factors will be involved. And this, too, is a profound subject. It's not like many time-travel novels where I just teach people and they can use it. That's pure bullshit.
Numerical symbols and units of measurement were controlled by the imperial court.
You said it can be changed if it is changed?
If the imperial court knew that Liangzhou Prefecture was so arrogant, they might kill you.
Therefore.
Liu Zheng has never deliberately pursued Arabic numerals. He believes that in this regard, ancient Chinese wisdom is completely sufficient.
and……
Even when the industrial revolution was about to come, he still adhered to the concept of "Chinese learning as the foundation and Western learning as the basis". To completely abandon the traditional culture of the Chinese nation is to break one’s own arms.
Combining Chinese and Western styles is the way to go.
Change should come step by step.
Rice is also eaten one bite at a time. At present, the Longyan Dynasty has not yet integrated with the entire world. The emergence of Arabic numerals is of little significance. It may even overturn the already mature algorithm.
In this way, the gain outweighs the loss.
When that day comes, it will come naturally.
Until today.
When he saw this huge calculation tool, he became even more determined!
The calculation tools of this entire platform are made of long and short sticks, but they are different from ordinary calculation tools because there are too many sticks. This calculation can be semi-mechanized. No need for anyone to fiddle with each one!
The sticks, gears, and scales are exquisite and extremely complex, which is breathtaking!
The calculations on the tall building are not only on this plane, but also on the walls on the four sides!
The sound of crunching work seems to be non-stop.
With the bonus of mechanism skills, calculations are always at work.
"when!"
"when……"
At this time, I don’t know which mechanism was touched downstairs. It may be that some information and data were entered, causing the calculation to start rapidly, and then slowly stopped...
The person who was guarding the calculation rang the big bell next to it.
"T-shaped cross is eighteen, dot is empty, small kindness!"
"Xiao Shan!"
The voice came out melodiously, and the entire college praised it one after another.
And as the calculation worked at a rapid speed, the name with the character "D" Hengshiba began to appear on the calculation plan on the wall, and quietly rose up one...
Not only that.
Because of Liu Zheng's calculations, he also discovered that there were some changes in several names next to the "D" character "eighteen"...
"This, this, this..."
Even though Liu Zheng came from later generations, he was dumbfounded at this time.
At this time, Jieyu said beside him: "They both belong to the Seven Kills Astrology Chart, and they may cooperate or be hostile... A change in one person will naturally affect the entire star chart."
sharp!
Liu Zheng took a deep breath after hearing this.
Yes.
Even if this thing looks so simple to future generations. Some people even sneered, who can’t figure out these things?
However……
Not so!
The thing that Liu Zheng saw in front of him, with the blessing of mechanism skills and thousands of years of inheritance and perfection, was no longer just a calculation! This can even be compared with the most powerful analog computer in human history, the Antikythera Machine!
No!
This thing should be more complicated than the "Antikythera Machine"!
Because the Antikythera Mechanism is just a tool used to calculate the cycles of celestial bodies. The complex and huge calculation in front of us can almost calculate any mathematical problem in the world!
wisdom.
This is human wisdom.
This is the wisdom of the Chinese nation, this is the wisdom of Wangbei Academy!
For the first time, Liu Zheng, as a time traveler, began to resonate with this world. He couldn't help but sigh: "Wangbei Academy is well-deserved! I almost bombarded the hard work of thousands of predecessors, I am very ashamed!"
Wang Chao laughed loudly, feeling a little proud after being praised by Liu Zheng. However, when he thought about how he could compete with this young man, he secretly shook his head: "It's not important, these are not important... …”
"Those who join the world should be able to distinguish between good and evil in order to record their merits."
"Only those with full merit can be born..."
He pointed at the top of the calculation chip and chuckled: "In the past three thousand years, there have been very few people born in the academy, only seven or eight. Liu Zhizhou, do you still dare to try?"
Liu Zheng then looked around.
Immediately his whole body was shocked.
At the top, there are several shining names. Each one is a famous person in this world!
A thousand years ago, General Chang destroyed 50,000 Xiongnu with 800 soldiers!
Five hundred years ago, the miracle doctor Hua Chen single-handedly quelled a plague!
Four hundred years ago, a scheme plunged the seven southern barbarian kingdoms into chaos. The most poisonous person in history who kept the Longyan Dynasty stable for fifty years, Xia Gang!
Three hundred years ago...
Liu Zheng took a deep breath.
Today he finally understood why the academy has been here in Liangshan for so long.
He finally understood.
Why is this academy called Wangbei?
They kept looking at Long Yan.
They have always been looking towards Long Yan.
They have been looking up to Long Yan.
They are North Lookers.
same……
They also guarded the Longyan Dynasty and the people of Longyan in another way.
Their standards of good and evil explain everything.
He couldn't help but bowed deeply in awe.
clown……
It’s actually been me all along!
