"I can't remember, but can't you?" Tang Yue said, "With you here, you can help." ”

The old cat has one eye open and one eye closed.

"Want me to help?"

Tang Yue nodded.

"Call Daddy." The old cat hooked its paws.

Tang Yue frowned, "What's it called?" ”

"Daddy."

"Hey."

"The work you want to do is a huge project that no one has ever done before, and it will take decades for the ancient historians to revise the history only for the previous dynasty, and you have to record the entire human civilization." The old cat yawned, and his ears moved, "Civilization is an overly complex concept, it covers history, culture, technology, art, everything you create and everything that creates you, if you write the entire development process of human civilization into a book, I think that book is thick enough to circle Mars several times." ”

Tang Yue was a little surprised, he knew that this project was huge, but he didn't expect it to be so big.

He has no concept of history, Tang Yue's understanding of history mainly comes from high school history textbooks, which are only a few pages in history textbooks for hundreds of years, and the name of Qin Shi Huang, an emperor through the ages, appears only a handful of times.

"Researchers at the Chinese Academy of Social Sciences spend a lifetime studying a dynasty, and they may not be able to understand it, so how can you write a book and write a biography for all mankind?" The old cat sneered, "Can you tell the difference between Roosevelt and Roosevelt Jr." ”

"Let's be brief, we can be brief." Tang Yue made concessions, in view of his own conditions, he really did not have the ability to describe the entire human civilization, if he accidentally made a mistake in the year of birth and death of Emperor Wu of the Han Dynasty, I don't know if Mr. Liu Che will chase him to Mars, which is 100 million kilometers away, to protest against him.

"We can start with a frame in chronological order, like a chronicle, and then slowly fill it in, and fill it in wherever we want." Tang Yue went on to say, "From Beijing, Yuanmou people...... Should it start with Neanderthals? ”

"Why don't you start in Cambrian?" The old cat snorted, "Start with the grotesque worm." ”

"Great idea!" Tang Yue slapped his face, "The earth has disappeared, and we should also write a biography for the history of the earth." ”

"Be your uncle...... Do you know what it means to do what you can? The old cat opened his eyes and waved his paws, a little helpless, "You want to record from the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian, Triassic, Jurassic, Cretaceous, Paleogene, Neogene all the way to the Quaternary?" Do you live longer than Pengzu? ”

"Let's be brief, let's be brief." Tang Yue said stupidly, "For example, it can be recorded that the Jurassic was the most prosperous period of reptiles in the Mesozoic Era, and there were ...... on the vast continent Living ......"

Tang Yue found that he didn't have much research on paleontology, and he couldn't even remember the names of a few dinosaurs.

"Life with a dragon!"

Tang Yue finally remembered a name.

The old cat silently held his forehead.

"Platesaurus is a species of the Triassic period."

"During the Jurassic period, the supercontinent began to break up, gymnosperms reached their peak, and there were many kinds of reptiles, among which ornithischian and sauropod dinosaurs developed, ornithischian dinosaurs included stegosaurus, and sauropod dinosaurs included Allosaurus, Domelosaurus and Brontosaurus." Mai Dong's voice sounded in the channel, and the girl laughed crisply, "Is that okay?" ”

“Bingo！” Tang Yue snapped his fingers, "It's so perfect, girl!" That's it! That's it, let's start with Cambrian! ”

The old cat covered his face silently.

It didn't dare to say anything more, "Why don't you start with the Big Bang?" ”

Because it is really possible for this second product to be slapped on the head, it started with Bigbang.

Obviously, it is impossible to complete this idea with Tang Yue and Mai Dong alone, so in the end, it is the old cat who really needs to trouble, and the old cat does not want to make himself uncomfortable.

"Okay, okay, you can start wherever you want." The old cat sighed, "But what are you going to use for the record?" Do you use paper? Do you use a hard drive? Or do you carve the words in stone? ”

There was a large stack of scratch paper in Kunlun Station, which Lao Mai brought to overcome Goldbach's conjecture, but then Lao Mai became addicted to the Elder Scrolls and couldn't extricate himself, and this lofty ambition was thrown out of the clouds.

"You can't use paper, the information density is too low, the capacity is too small." Tang Yue shook his head, "We don't have so much paper, we don't have so many pens, and we don't have so many people. ”

It was unthinkable to record the history of the earth on manuscript paper, and the efficiency of manual manual recording was too low, and in the pre-printing era, books and culture were disseminated by professional scribes, who worked all night to transcribe the text for months on end, and in the end the meagre production still made books the exclusive preserve of the aristocracy.

The use of hard disks may be able to do in terms of capacity, there is no shortage of hard disks in Kunlun station, dozens of hundreds of terabytes of hard disks are more, a Chinese character only occupies two bytes of space, and a letter only occupies one byte of space, if all used to store text information, the space of these hard disks is enough to put all the books in human history.

With only Tang Yue and Mai Dong, there is no need to worry about the lack of hard disk space.

"How long does the information on the hard drive last?" Mai Dong asked.

"It's hard to say, the harsh environment on Mars will greatly reduce the life of hard drives, solid-state drives that use storage particles are more likely to be damaged, and mechanical hard drives have a slightly longer lifespan, but they can't survive a hundred years." The old cat shook his head, "Even if you record the information in the hard drive, where can the hard drive be kept?" ”

"This is the place where the environmental conditions on Mars are the best." The old cat pointed to his feet, "The life of Kunlun Station is longer than yours, but after you die, it will not last long without maintenance, at most fifty years, Kunlun Station will be completely abandoned, and after a hundred years, the information and data you engraved on the hard disk will be damaged and lost." ”

Tang Yue and Mai Dong both fell into deep thought.

In a sense, they are writing epitaphs for human civilization, and the epitaph is engraved on the tombstone for future generations to see, and it will be preserved for a long time, even if the coffin bones in the tomb have rotted and turned into dirt, but his name and deeds are still known.

Therefore, Tang Yue hopes that what he has written can be preserved for as long as possible.

Neither paper nor hard drives will work.

As for carving words in stone, this is indeed a romantic idea.

If conditions permit, Tang Yue also wants to use the entire Martian surface as a paper, with a mighty team of excavators and forklifts, to engrave words on Mars, so that the whole solar system can see it.

But Tang Yue only had a spoon-like shovel in his hand.

At best, he could only engrave his name in stone.

But Mr. Lu Xun said that the name carved into the stone will rot earlier than the corpse.

Mr. Lu Xun: ...... I didn't say that, Zang Kejia said.
