Now that things have come to this, they can no longer object anyway, so they can only acquiesce to the current situation.
"Everyone, I will announce a few things today." After Li Ke went to court, he spoke directly without waiting for everyone to speak.
"Where is the Secretariat of the Taishi Bureau?" Li Ke asked.
"I'm here." Li Chunfeng, who was standing behind, stood up.
"Come to Liangliangyi Hall later. I have a set of books on astronomy and calendars here, including some books on data calculations. You can take them back later, study them carefully, and then formulate a new calendar." Li Ke was very happy. A brand new order was issued directly.
"Yes!" Li Chunfeng was a little confused, but he still bent down and saluted immediately. Didn’t His Highness say before that they need to study these themselves? Has His Highness already researched the new astronomical and calendar data by this time?
But what Li Chunfeng didn't know was that Li Ke's change of mind came from the Xizhou information sent before.
So Li Ke made changes, such as the calendar. Li Ke decided to change the era directly with the Tang Dynasty! From now on, we will directly take out the calendars for future Gregorian calendar eras.
The Gregorian Calendar Era itself has nothing to do with the Western faith in Jesus Christ. What Li Ke refers to is the Gregorian Calendar Era that is determined based on the sun's revolution. The Gregorian Calendar Era that has been scientifically proven by later generations is more accurate and can be directly applied to the finished product.
After giving the finished product, he told Li Chunfeng and others how to calculate the ecliptic angle, revolution orbit, etc., and let them learn and understand on their own.
The traditional lunar calendar is flawed. In fact, the calendar of the Tang Dynasty currently uses the "Wuyin Yuanli" created by Fu Renjun and Cui Shanwei. This calendar lasted for 46 years. In other words, in fact, the ancient calendar The calendar has been changing all the time. Later, Li Chunfeng corrected the errors and omissions in this calendar.
It is undeniable that the lunisolar calendar in ancient China is a cultural inheritance, but in fact, this calendar was not perfect until the Tang Dynasty. The lunar calendar that paralleled the Gregorian calendar more than a thousand years later was actually a luni-solar calendar. It was the Zijin calendar that began to be used in 1929. Throughout history, almost all dynasties have revised the calendar.
Therefore, the ancient calendar was not as thorough as the lunar calendar of more than a thousand years. Li Ke made a decision after repeated thinking.
Using the same dual-calendar parallel method as in later generations, since the Tang Dynasty has already used the Tang era, it can be calculated directly according to the AD era.
Solar terms such as the twenty-four solar terms can be directly added to the Gregorian calendar. This does not conflict, and the accurate calculation method of the Gregorian calendar is also conducive to inheritance. Traditional festivals such as the Mid-Autumn Festival rely on the complete version of the lunar calendar from later generations.
To put it bluntly, in this world, after the Gregorian calendar was adopted by Li Ke, even in modern society more than a thousand years later, the whole world has to admit that this is the Tang calendar!
Li Ke decided to use a two-pronged approach. He decided that in the first year of the Gregorian calendar, he should not only use cultural influence, but also use scientific and technological influence. Even if scientists study it more than a thousand years later, they will have to marvel that China's ancestors are so awesome. The Gregorian calendar, which revolves around the sun, has long been discovered.
It also accurately calculated that one revolution equals 365 days, 5 hours, 48 minutes and 46 seconds.
Li Ke planned to calculate the concepts of hours, minutes and seconds, although the sexagesimal system of modern time actually came from the ancient Semitic people in the 3rd century BC.
But who made Li Ke get used to it? Since Li Ke is used to it, everyone has to get used to it. As for future generations, let them be amazed.
Later definitions of time, such as the pendulum of one second from the beginning, were later defined as the atomic second: the transition between the two hyperfine energy levels of the ground state of the cesium 133 atom corresponds to the duration of 9,192,631,770 cycles of radiation.
Because atomic seconds are not affected by the environment, they are more accurate, and atomic seconds serve scientific research. But the atomic second cannot escape the astronomical second.
It is not so precise in daily use, but time and measurement units in later generations are related. For example, the length of the swing arm of the seconds pendulum is 1 meter.
It is not difficult for craftsmen to make a pendulum clock. With a pendulum clock, timekeeping will naturally be more accurate. A pendulum clock that relies on gravity and is controlled by a clockwork will naturally be more accurate than current timekeeping.
Li Ke decided to introduce the Gregorian calendar through Li Chunfeng and others first, and then improve the time and clocks. In the future, he would probably build a large clock tower in Chang'an City.
This thing tells the time for the people in the city, and if more small pendulum clocks are built and adjusted together, the error will gradually be reduced.
Anyway, what time it is, it is definitely not as accurate as the astronomical observation positioning in later generations, but it doesn't matter, it is accurate enough for this era.
From now on, all these inventions will be invented by me, Datang!
Let future generations of scientists be shocked.
The research and development of astronomy is too slow. Just produce the results and let them slowly absorb and digest them. When the sandpaper and glass manufacturing technology becomes more advanced later, we can take out the telescopes and provide Li Chunfeng and others with night observation of the sky. Click tool.
All in all, Li Ke is ready to recommend the Gregorian calendar, hours, minutes, and seconds.
Of course, please call this calendar the Tang Dynasty in the future! Tang Dynasty Gregorian calendar!
"Minister of Civil Affairs." Li Ke said.
"Here." Huangfulin stood up with an anxious expression.
"After this meeting of the Ministry of Civil Affairs, we will investigate the distribution of pack horses and donkeys among the people of the world. Horses and mules that are reproduced by male donkeys and female horses are very suitable for processing and can replace cattle for farming to a certain extent. You need to bring the folk All relevant data have been investigated. I checked the data from previous years and it was very inaccurate."
"In addition to folk data, you also need to give me a rough statistics on the distribution of animal power in various Taoist states in the Tang Dynasty. I will try my best to find ways to bring a large number of pack horses into the country from Xizhou, Xueyantuo, Western Turks and other places." Li Ke The order was given directly.
"Yes..." Huangfulin agreed with a grimace. This work was too tiring. This is not an easy job, but who asked the Ministry of Civil Affairs to do this?
"Minister of Industry." Li Ke said again.
"I'm here." Duan Lun also stood up directly.
"The Ministry of Industry is responsible for farming matters, so the Ministry of Industry is also responsible for this investigation on animal power. You should assist the Ministry of Civil Affairs in the joint investigation. You must not pass the buck to each other and speed up efficiency. I want all the data before the end of this summer." Li Ke said with a cold expression.
"Your Highness..." Duan Lun and Huangfulin were startled. Just one spring and summer? How can this be!
"Can it be done?" Li Ke interrupted them directly and asked.
