Chapter 1816 Two Liu who deviated from the classics
Chang'an Workshop's wine offering is not the person in charge of the production affairs of the workshop, but more like a chief engineer. The Chang'an Academy's wine offering is also the same principle, similar to the leader of the academic affairs group or the dean of teaching in later generations.
Liu Zhuo and Liu Xuan were both Ph.D.s from the Northern Zhou Dynasty. Although they were from Jizhou, they both served as officials in Chang'an. After all, in terms of inner belonging, they were more inclined to follow Yang Jian. Later, as everyone surrendered to the Han Dynasty, the two of them were originally
Some "talents" naturally came to the fore when the Han Dynasty established academies and workshops.
Liu Zhuo's talents are arithmetic and astronomy. He should be the first astronomer and mathematician in the Sui Dynasty in history. He single-handedly calculated the laws of solar and lunar eclipses and solved the problems among the people and the public.
The fear of these two normal celestial phenomena is a major breakthrough in the Chinese calendar.
Liu Xuan is an out-and-out Confucian scholar, but he is different from those Confucian scholars who shake their heads and wish that every sentence is a classic of the ancients. He is even a little deviant. What he mainly does is to question, people are not sages.
, no one can have faults, even sages have deviations. This guy put forward the "Spring and Autumn Rules Theory", pointed out the irregularities in "Spring and Autumn", and criticized the biases in "Zuo Zhuan". For a while, he was considered
Alternative.
Because both of them were born in Jizhou and were related in their inheritance, they were called "Er Liu", but I don't know if they were called "Er Liu" together. Is this to praise them, or to say that their thoughts are somewhat deviant.
In Li Xingchen's view, Er Liu is indeed the talent that the Han Dynasty needs now. Needless to say, Liu Zhuo is an astronomer and mathematician. The interesting thing about the ancients is that the astronomical knowledge of mathematicians and the astronomical knowledge of astronomers
Mathematics knowledge must be good. This should be because the ancients were eager to explore the truth of destiny, and mathematics is undoubtedly a very important tool.
Nowadays, the design of various new equipment in Dahan's workshop is inseparable from precise calculations. In particular, streamlined production has strict requirements on calculations. If any number is miscalculated, it may lead to errors produced on the assembly line.
A large number of products were scrapped.
In addition, there is such a thing as destiny, if you believe it, there will be it, if you don't believe it, there will be nothing. Li Xingchen, as a time traveler, certainly does not believe it, but if he does not believe it, he may not be able to consolidate people's hearts and develop in astronomy.
It can help Li Xingchen make better use of the phenomenon of destiny. Secondly, it can also help Li Xingchen and those who come after him to be more relaxed when they want to eradicate the idea of destiny. After all, this will not be done at the same time, so there is no conflict.
Not to mention that the current theories of Mathematics, Physics, etc. are actually only in their infancy. People's understanding is limited to experience. Experience is important, but it often limits the development of technology. Without theoretical support,
Just relying on experience, any technological development is a castle in the air.
China has always been a pragmatic nation, focusing on the present, solving the problem of food and clothing, and solving the problems of construction and development through its own hard work and sweat. However, it is precisely because of this pragmatic thinking that it often limits the development of theory.
During the Southern and Northern Dynasties, mathematics actually experienced a rare period of rapid development, giving rise to mathematicians such as Zu Chongzhi who were admired by later generations. In Li Pingchen's view, the reason for such a result may have something to do with the retreat style during the Southern and Northern Dynasties.
People tend to talk in general terms and imagine, and naturally it is easier to achieve breakthroughs in theory. However, the disadvantage of doing so is that it is often difficult to implement in practice. This trend has even been spread downwards, so that later on
Zhu Xi sighed with emotion, "I know that I must do this."
Now Li Xingchen wants to develop industry and work hard to rejuvenate the country. Industry is one of the keys to rejuvenating the country. The development of technology can bring obvious wealth, but industry ultimately needs scientific support.
Liu Zhuo will soon be given such a responsibility by Li Xingchen.
Listening to Li Xingchen talking about some very basic physical theories and mathematical laws, Liu Zhuo opened his mouth in surprise.
In fact, his knowledge is mainly based on "Nine Chapters of Arithmetic". "Nine Chapters of Arithmetic" can be regarded as the master of ancient Chinese mathematics. However, due to various factors, in fact, "Nine Chapters of Arithmetic" is difficult to understand and not many people can understand it.
Pay attention, and the above theories and laws are relatively fragmented compared to the simple and clear formulas of later generations.
What Li Xingchen needs is someone who can continue to conduct theoretical research and truly sort out knowledge similar to modern mathematics and physics in later generations. It is difficult to widely teach and disseminate obscure and difficult texts, and can only be simplified and formulated.
Not only can more people learn knowledge quickly, but it can also be applied more conveniently in production practice.
Li Xingchen wrote a series of numbers on the paper. If it were a descendant, he could clearly recognize that these were Arabic numerals that were widely used throughout the world in later generations. Then he wrote the corresponding Chinese characters below these numbers.
"Your Majesty, what is this?" He could vaguely understand what Li Xingchen meant, and Liu Zhuo's eyes shone with light. This was the look of a scholar who had suddenly reached the extreme after having reached the extreme. Liu Zhuo's change in expression made Liu Xuan next to him
He also came over curiously.
"This is a way to express from zero to nine. It was passed down from Tianzhu. I learned about it from the mouths of merchants in the Western Regions." Of course, Li Xingchen couldn't say that he knew this or that he was the one who knew it.
He was a little embarrassed about the invention, after all, Arabic numerals had actually been born in this era.
The name of Arabic numerals is Arabic, but the inventor was actually a Punjabi in northern India from the third to the fifth century AD. At that time, because the caste system was already conducive to the rapid development of society, mathematics naturally developed rapidly and was born.
The relatively basic numbers were later cited by the Arabs when they conquered India, and these numbers have been spread throughout Europe with the swords and caravans of the Arabs.
It is a pity that China at that time happened to be at the turn of the Tang and Song Dynasties. The entire Western Region had been closed and the Silk Road was cut off. Therefore, this kind of digital culture had no chance to enter China again. China was an ancient trading partner of the Arabs until the late Manchu Dynasty.
After opening his eyes to see the world, he began to systematically learn this counting method that has been spread around the world for thousands of years. This is what Li Xinchen regrets as a later generation.
The biggest advantage of Arabic numerals, or Punjabi numerals, is that they make calculations simple and clear. Later binary systems are actually one of the extreme manifestations of simplified calculations.
Only when the expression of calculations is simplified can people use these numbers to create more calculation methods.
