Da Qin: The First Emperor wanted to train me to be the empress

"And what do these things mean?"

Xu Man: "Father, this is mathematics and physics, and it is the foundation for Great Qin to move towards science and technology in the future."

Xu Man was not surprised at all that his father didn't understand the knowledge inside.

After all, the ancient Chinese in your time period all learned ancient and inherited knowledge such as astronomy, geography, humanities and etiquette.

He doesn't pay special attention to arithmetic and other science subjects.

But now that she has returned from more than two thousand years ago, she naturally has to pay attention to these technologies.

Ancient culture must be passed on, and these technologies must also be carried forward into culture.

After global unification in the future, China's goal is still to move towards the sea of ​​stars and even the more distant universe.

Even if her father and her generation cannot achieve such an ambitious goal, as long as the seeds are sown, they will be able to achieve it one day.

In order to facilitate his father's understanding, Xu Man explained: "For example, the ice I taught people to make a few days ago was actually made through this knowledge."

"Father, the wind fan installed here is produced using physical principles."

……

She cited several visible examples in succession, and Ying Zheng suddenly realized: "That's it."

"How can these things be so useful?"

Xu Man: "Yes, so I hope that the people of Great Qin can learn more new knowledge in the future. Only in this way can we develop in both directions steadily and quickly."

"As expected of my glorious chapter, you can imagine this."

Ying Zheng looked at Ninth Girl Chongdong, took a sip of the tea she handed her, and looked at her with gentle and expectant eyes.

"My father is very much looking forward to the products that will appear in Great Qin more than two thousand years in the future."

Xu Man: "..." Is Father going to show off his cards?

Should I tell him the truth? Unexpectedly, Ying Zheng said such a sentence. Seeing her silence, he smiled and did not continue.

Instead, he changed the topic and asked: "What subjects do your royal brothers like?"

"The third emperor brother Yuan prefers physics, the fourth emperor brother Cheng likes chemistry, the fifth emperor brother Gao prefers mathematics, and the second emperor brother Zhe prefers cultural heritage..."

Xu Man briefly explained the preferences of the royal brothers.

"So far, they are very enthusiastic about learning, but they are still in the stage of laying the foundation. They need to work harder to develop new things on their own."

"Then you should pay more attention to making them learn well and solidly."

Ying Zheng nodded with satisfaction, then smiled and sighed: "It turns out that in addition to the knowledge of various schools of thought that my father knows, there are so many things that my father doesn't know."

Xu Man: "Father, in fact, the mechanisms of Mohism and Gongshu's art have a lot to do with mathematics and physics."

"It's just that their knowledge has not been turned into textbooks that are easy for the public to learn, but has been passed down from generation to generation within their own families."

Hearing what his daughter said, Ying Zheng nodded thoughtfully: "It turns out that these things have already appeared, but ordinary people can't access them."

"Well, that's what it means."

Xu Man nodded, "Also, the Taoist alchemy technique actually has something to do with this, but it is mainly based on chemistry. Substances with different components are condensed together to produce chemical reactions, and new things appear."

"So in future generations, mathematics, physics, and chemistry will not be separated."

Ying Zheng pointed to the last question and asked, "Then what's going on with this?"

"What kind of bacteria, what kind of cells are these?"

Xuman looked at the content on his father's finger and burst into laughter: "Father, this is biology, a relatively advanced course."

"I asked this question just to see if anyone in the Qin Dynasty is interested in it." (End of Chapter)
