Chapter 1091
Calculate!
What's this?
This is the crystallization of the Chinese nation, its entire culture, and its high wisdom in mathematics!
It should be mentioned here separately.
Some people ask, why did Liu Zheng travel back in time for so long, and he didn’t even do Arabic numerals, so what kind of database did he dare to do?
Very simple.
In fact, in a historical sense, in terms of accuracy, and in terms of advanced algorithms, Chinese calculations in history are no worse than Arabic numerals! This is because Chinese calculations implemented the decimal system thousands of years ago.
!
The ancient Chinese decimal system of arithmetic notation is a great creation in the history of world mathematics. Comparing it with the notation methods of other ancient nations in the world, its superiority is obvious. The number system of ancient Rome did not
The place value system has only seven basic symbols, so it is quite difficult to memorize larger numbers. Although the Mayans in ancient America knew the place value system, they used 20 bases; the ancient Babylonians also knew the place value system, but used 20 bases.
Carrying 20 requires at least 19 digits, and carrying 60 requires 59 digits, which makes counting and operations very complicated. It is far inferior to the decimal system that can represent any natural number with only 9 digits.
Simple and convenient. The reason why ancient Chinese mathematics has made many outstanding achievements in calculations should be attributed to a certain extent to this arithmetic notation method that conforms to the decimal system. Marx called the decimal system in his book "Mathematical Manuscripts"
The carry notation method is "one of the most wonderful inventions", which is certainly 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 a corresponding number of arithmetic chips arranged vertically and horizontally. 6-9 are represented by the above arithmetic chips plus the corresponding ones below.
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. When zero is encountered, leave it blank. This counting method
Following the decimal system. The age of the appearance of calculations is unknown, but according to historical data, it is speculated that calculations appeared in the late Spring and Autumn Period and the early 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, calculation plays an indispensable role. It was originally created in China before the invention of the abacus and is the most effective calculation tool. The early days of ancient Chinese mathematics
Developed and sustained development both benefit from calculation.
What is the meaning of Arabic numerals?
In fact, just like the calculation, they just 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 notation.
Another advantage is that it is relatively simple to write Alaba numerals.
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 the same as words. If you want to overthrow and adopt another one, it will involve many political factors. And this is also a profound subject. It is not like many time-travel novels, I just teach it casually.
Just teach people and they can use it. That is pure nonsense.
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 practical application". Completely abandoning the traditional culture of the Chinese nation would be a self-defeating move.
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 composed 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. There is no need for people 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 stop...
The person who was watching over 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 whole college praised it one after another.
