"And these things, what do they mean?"

Xu Yan: "Father, this is mathematics, physics and chemistry, which is the foundation for Daqin to move towards science and technology in the future. ”

For his father who doesn't know much about the knowledge in it, Xu Yan is not surprised at all.

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

I don't pay much attention to science subjects such as arithmetic.

But now that she has returned from more than 2,000 years later, it is natural that she will pay attention to these technologies.

Ancient culture should be inherited, and these technologies must also be carried forward to culture.

In the future, after the unification of the world, Huaxia's goal will still be to move towards the sea of stars and even the more distant cosmic starry sky.

Even if her father and her generation can't achieve such a lofty goal, as long as the seeds are planted, they will be able to achieve it one day.

In order to make it easier for her father to understand, Xu Yan explained: "For example, the ice I taught people to make a few days ago can actually be made through this knowledge. ”

"And the wind fan you installed here is produced by using physical principles."

……

She gave a series of several visible examples, and Ying Zheng suddenly realized: "I see." ”

"How can these things work so well?"

Xu Yan: "Yes, so, Erchen hopes that the people of Daqin can learn more new knowledge in the future, so that two-way development can go steadily and quickly." ”

"It's worthy of the Huazhang of Me, you can think of it."

Ying Zheng doted on the nine girls, took a sip of the tea she handed over again, and looked at her with gentle and expectant eyes.

"Father is looking forward to the emergence of products in Daqin in the next two thousand years."

Xuyan: "......" Is the father going to have a showdown?

Shall I tell him the truth?

Ying Zheng said such a sentence, and seeing that she was silent, he smiled and didn't continue.

Instead, he changed the conversation and asked: "What disciplines do you like about your royal brothers?" ”

"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 inheritance. ……”

Xu Yan briefly said 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, and they still need to work hard to develop new things on their own."

"Then you have to bother more to let them learn well and study solidly."

Ying Zheng was satisfied, and then sighed with a smile: "It turns out that in addition to the knowledge of the sons and hundreds of schools that my father knows, there are so many things that my father does not know. ”

Xu Yan: "Father, in fact, the mechanism of the Mo family and the public loser has a lot to do with mathematics and physics. ”

"It's just that their knowledge has not been made into a textbook that is easy for the public to learn, but has been passed down from generation to generation by their own families."

Hearing what her daughter said, Ying Zheng bowed her head thoughtfully: "It turns out that these things have appeared a long time ago, but ordinary people can't touch them." ”

"Well, that's what it means."

Xu Yan nodded, "There is also the Taoist alchemy technique that actually has something to do with it, but it is mainly based on chemistry, and substances of different ingredients are condensed together to produce chemical reactions, and new things appear." ”

"So in later generations, mathematics, physics, and chemistry are inseparable."

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

"What kind of bacteria, what kind of cell is this?"

Xu Yan looked at the content of her father's finger and laughed: "Father, this is biology, a relatively advanced course. ”

"I came up with this question just to see if anyone in our Great Qin world is interested in this." (End of chapter)
