Night fell slowly, but the scene was filled with stunned expressions. Even Liu Xinyu couldn't care less about the Queen's majesty. She opened her mouth wide in surprise and stared at the 'globe' in front of her.
Today, everyone finally has the concept of ¡®planet¡¯!
It has been more than three hours since the sea trial ended, and Zhao Dahe was talking about his great discovery with saliva flying around.
Using the projection length of the stick at noon measured in the Taotu Continent and the Red Lotus Sect, combined with the projection length of the stick at noon in the Kingdom of Qixia, plus some knowledge passed down by Zhao Dahe himself, etc., Zhao Dahe used Zhang Using a new mathematical knowledge calculation, Zhao Dahe calculated the diameter of the earth for the second time after repeated proofreading:
The diameter last calculated by Zhao Dahe was 126,000 kilometers;
This time Zhao Dahe calculated the diameter to be 128,700 kilometers.
Last time, Zhao Dahe calculated based on the records and data of the sect, as well as the Zhoutian star chart, plus the Zhang family's mathematics, etc. - there were many approximations. This time, we used Zhang's mathematics, stick projection, etc. to conduct new calculations, corrected some divisors and errors, and obtained a more accurate number.
The diameter of the earth is 128,700 kilometers, and we live on a star! The area displayed by the Kuo Dixiang is only about one-tenth of the surface area of ??the star!
There are still nine tenths of the world, which is an unknown world!
Zhao Dahe¡¯s calculations were very complicated, and many of them were even helped by Huang Mingshan and others. Huang Mingshan and others have grown into scientific staff and pillars of the Zhang family.
Looking at the dense calculations and proofs on the three-foot-long gastrodia paper scroll, everyone felt a little dreamy.
And this time Zhang Shengye did not refute, because compared to Zhang Hao's "random talk" at the beginning, Zhao Dahe proved his conclusion with mathematical methods and various evidences!
Precise numbers make all language pale.
The earth beneath our feet is a star, and we ourselves are people living on the stars! After discussion, Zhao Dahe and Zhang Hao named the planet under their feet: Tianyuan.
The so-called Tianyuan is the beginning of heaven and earth and the center of heaven and earth. In ancient legends, there are 366 stars in the sky (it is said that Zhang Hao didn't know how to count these 366 stars when he looked at the sky full of stars), but currently what everyone observes is 365 stars. One star disappeared.
For a long time, everyone has had many speculations about this missing star. One of them is that there is still an "original" star that has not been found. Everyone named this star ¡®Tian Yuan¡¯.
But over the years, many astrologers and even many practicing masters who study "Zhou Tian Gong" have been looking for this 'Tian Yuan Star'. As a resultit was right under my feet!
Such a result made countless people at the scene think in knots. It was really too dramatic.
Then Zhao Dahe carefully adjusted the direction of the newly made "globe", or "Tian Yuan Yi", so that the "Kuo Di Xiang" on the Tian Yuan Yi tilted up. It rises in the east and sinks in the west.
But for the time being, Zhao Dahe has no concept of longitude and latitude, the Arctic Circle, the equator, etc. He just makes adjustments based on some of the information he knows.
But this adjustment is very similar to what Zhang Hao made before.
Zhao Dahe adjusted for a while, then took a few steps back to take a look, and then said to everyone: "Everyone, this should be the approximate location on the map on the map."
Liu Xinyu finally let out a slow breath and spoke: "I have a question, why are we in the north and not the south? Since we live on the same 'planet', why can't we be in the south?"
Zhang Hao smiled: "It's very simple, because we discovered this secret, so we stipulated that our place is the northern hemisphere!"
¡°Can it still be like this Liu Xinyu blinked in a daze for a moment, and finally had to nod in agreement. Yes, we discovered it. Of course we are in the northern hemisphere. Traditionally, the north-south direction is considered noble; the east-west direction is respected, and the east is respected.
But Liu Xinyu still has questions, "Since we live on a planet, why don't we enter the outside world? What is between each star? How far away is it? Can we reach other stars?"
Zhang Hao looked at the Queen dumbfounded: Are you thinking of expedition to other planets now? You are a bit ambitious! Well, having ambition is a good thing, it¡¯s better than having no goals at all. Having said that, practitioners have a long lifespan. Maybe Liu Xinyu will conquer the stars one day.
But for Liu Xinyu¡¯s current problem?More discussion was posted - why didn't we fall? What force is binding us? Could it be is this the legendary power of the stars?
And here comes a more serious question: Since we are on the stars, where is the legendary fairyland? So where is hell?
The discussion intensified, and the Zhang family took the opportunity to push Zhao Dahe to the front desk and use this to attract many people's attention.
This time, Zhang Hao did not use the name of Dayang Group, but the name of ¡®Zhang Family¡¯. Knowledge must be in your own hands!
In this atmosphere, the Zhang family finally made an important decision: to build a school. A school that teaches various scientific knowledge such as cultivation, alchemy, industry, commerce, geography, etc., and recruits students from the country of Qixia.
And the Zhang family promises: free education!
The name of the school: Beidou University.
For a time, the country of Qixia became even more lively.
