Hearing his girlfriend say so solemnly, Gu Yu couldn't help but completely put away his contempt, and sincerely asked:

"It's called...... If the age of the things can be accurately determined, how can we prove the alternating years of the Shang and Zhou dynasties?"

Ma Yiyi flipped the stack of pictures in her hand to the next page.

The first page is a picture of the whole of the Ligui, and the second page is a close-up of the inscription inside.

Gu Yu glanced at it a few times, and his head suddenly grew. Those golden texts in the early years of the Western Zhou Dynasty, how could he understand them.

Ma Yiyi pointed out: "I know you can't understand it, there is a translation by experts from the Institute of Archaeology of the Chinese Academy of Sciences next to it:

King Wu Zhengshang, only Jiazi Dynasty, Sui Ding, Ke Du Shu has business, Xin Wei, Wang Zai Shi, give you something money, used as Tan Gong Bao Zun Yi.

In modern Chinese, it is:

The decisive day of King Wu's war took place on the Jiazi Day of a certain year, in the early morning of this day, there was such a celestial phenomenon as 'Sui Ding', and in the evening, only one day of fierce fighting, the merchant army collapsed, and King Wu won the world.

When King Wu was in the class teacher/thank the teacher, he gave a 'Yousi' bronze named Li, and Li used these coppers to make this gui. ”

"Yousi" is not a specific official position in ancient times, but is equivalent to the modern "relevant department".

Hearing this, Gu Wan had already smoothed out the context: the inscription of this Gui was the official of the relevant department named Li, when he took the bronze casting Gui rewarded by King Wu of Zhou, he asked the craftsman to give the narrative the reason for his "why he was rewarded and why he wanted to cast this Gui".

His IQ is still very high, but he usually doesn't study liberal arts, but at the moment, he is engrossed in it, and immediately draws inferences:

"So what do you mean is that if you accurately determine the year in which this Li Gui was cast, you can know which year King Wu's war took place, and you can also make up the 200-odd years of accurate chronology from the alternation of Shang and Zhou to the first year of nuclear supply?

But there's a big problem, I'm afraid I'm going to disappoint you. Because even if I invent the ion accelerator mass spectrometer, it is nothing more than the accuracy of C14 isotope abundance identification, which is several times higher than the current centrifugal method, but it still cannot achieve such a high accuracy as 1 year.

You may not know much about cutting-edge physics: the current traditional centrifugal measurement method has an error of as much as three to five hundred years, and the most accurate and accurate will not be less than two hundred years.

After I got on the ion accelerator mass spectrometry, the first generation of products may have an error of fifty or sixty years, and then I tried desperately to improve the accuracy, and there were still some in twenty or thirty years.

However, Western historians will probably not admit the error of several decades in their attack on China's lack of accurate chronology, right? On this issue, they are only attacking the chronology. And such a thing as chronology, as long as it is not accurate to one year, it is meaningless. ”

Gu Yu sighed, thinking that his girlfriend had been busy for him for half the winter vacation, and he had traveled so many archaeological institutes and national museums to the north and south, and he was going to run in vain.

Of course, Gu Yu is still very grateful to Ma Yiyi in his heart, no matter whether he succeeds or not, Ma Yiyi is so enthusiastic about running for him, which in itself makes him very moved.

This is a girl who struggles with him to change the world.

However, Ma Yiyi did not sigh, but smiled proudly: "Do you think that with my IQ, I would not think of this? It's not that I don't know enough about cutting-edge physics, but you don't know enough about how much I know about cutting-edge physics." ”

finally suppressed Gu Play a little in terms of IQ, and it was difficult for Ma Yiyi to think about it.

It's so rare.

Gu Wan's heart moved: "Then what other tricks do you have? Do you know that the ion accelerator mass spectrometry has decades of errors, but you still think that you can overcome it in the archaeological link?"

Ma Yiyi smiled smugly and pointed to the two words on the inscription photo:

"King Wu recruits business, only Jiazi Dynasty, Sui Ding, Ke Du has a business - the key lies in the word 'Sui Ding'. ”

Only then did Gu Play notice that his girlfriend had just sold a little, and he didn't say what the words "Suiding" meant when he translated.

But he didn't think it was a big deal, so he didn't ask, and just looked at Wen Shengyi.

Could it be that there is some very important mystery in this?

Gu Wan couldn't help but ask: "Don't sell Guanzi, what do these two words mean? Isn't it the meaning of casting a tripod this year?"

"You only cast a tripod this year! You also bought a watch last year!" Ma Yiyi scolded with a smug smile, "Combined with the cultural conventions of the Shang and Zhou dynasties and divination in case of good fortune, generally when the inscription describes this kind of major event of changing the dynasty, the last sentence of the record time is to record the celestial phenomena."

In this context, it means that the celestial phenomenon in the early morning of Jiazi Day is that the star of the year is located in the middle of the sky'. ”

"So what kind of star is this 'year star'?" asked Gu Yu eagerly.

Ma Yiyi: "The star of the year is Jupiter." ”

Gu played with great joy: "Jupiter...... Jupiter is located in the middle of the heavens, and this celestial phenomenon is indeed rare for decades, and the specific year can be accurately calculated by retrospective astronomical trajectory method......

If we use Jupiter's orbital period in the middle of the sky when it is at the dawn and dusk line of the earth, and then combine it with the carbon-14 isotope abundance identification of the ion accelerator mass spectrometry, we can indeed use the year when the two intersect to accurately calculate which year the Wuwang War, Shang and Zhou alternated!"

Before the existence of the Xia Dynasty was completely hammered, determining the year of King Wu's defeat means determining the year of the change of dynasties recorded in the history of the letter for the first time in Chinese history!

This significance is indeed extraordinary.

What about being "borrowed by heaven for 500 million years"? This time, my brother will let the Chinese civilization borrow an additional 200 years of history from me!

Gu Yu suddenly felt that he had chosen the book "The Order of Time" by Carlo Loweley, a physicist who was interested in the earth, as a foreshadowing and stepping stone for him to write Hawking's "A Brief History of Time" in the future.

Because of the scientific discoveries he is about to make, he is destined to attract great public attention on this topic.

Who else is more qualified to write about such a topic than someone who has extended the life span of the universe by 500 million years and the civilization of a country by 200 years?

Thinking of this, he immediately remembered an old friend.

He called his old classmate in high school, Feibach, who went to Tunghai University to study astronomy because of his major obedience assignment during the college entrance examination.

"Old Fei, you help me go to your school database to check the information, I'll come to see it in the afternoon, I want the historical record of Jupiter's signs. In what name, you can report my name, or if you can't, you will report Yuan Xiong, and the Provincial Observatory should also cooperate with you. If it weren't for me in the Ark, I would have asked my school directly. ”

Of course, the younger brother does not dare to have any resistance, and it is the honor of the younger brother to be able to run errands for the big guy.

So his horse boy got things done quickly.

After Gu Yu had lunch, he rushed to Tunghai University, checked it, and found three alternative years that he thought might be the year of King Wu's war at this stage.

"Jupiter appeared in the celestial center of the morning and dusk lines, in 1109 BC, 1046 BC, and 983 BC...... In other words, this is a once-in-a-63-year phenomenon, which is significantly lower than the measurement accuracy of the ion accelerator mass spectrometer I expected to design.

Therefore, as long as I make the machine, I can filter out which of the three alternative years measured by the current centrifugal method is the only truth. ”
