Chapter 160 Cao Pi from Heaven

He Yan said he would wait, but Ni Heng couldn't wait.

"You tell me and I'll find it myself!"

Mi Heng was just like a parrot that had just been released into the world. He was thinking about flying well, so how could he go to a tree branch to rest for a while?

He Yan saw that Mi Heng was not the kind of person who could stand his temper, so he decided to find something for him to do first.

Among the seven basic disciplines, mathematics, physics, chemistry, biology, astronomy and earth science are difficult to achieve breakthrough progress because the current theoretical and technical foundations are not very solid. Only "logic" has a very bright future.

It is also the most important basic discipline at present and the easiest to produce results.

Confucianism has the "Six Arts of the Gentleman", and the West also has the "Seven Arts" of ancient Greek civilization.

The so-called "seven arts" are the "three arts" of the Sophists of Athens - rhetoric, grammar and argumentation, plus the "four subjects" proposed by Plato in "The Republic" - arithmetic, geometry, music theory and

astronomy.

Among them, argumentation and geometry both require strong logic, which is also the final soil before the birth of logic.

Mi Heng is famous for his "eloquence". This "eloquence" not only refers to Mi Heng's bad mouth, but also refers to his rigorous logic.

Translation Translation means that Mi Heng can curse people quite well and in a very clear manner.

If you let such a person engage in logic, it would be a perfect fit for someone named Zheng to marry someone named He.

"Since you have this intention, let's discuss it together?"

"Logic" sounds abstract, but that's just because the Chinese sages did not write books specifically on this subject, but integrated this subject into the logic of famous debates.

The most famous among them are the "Three Biao Theory" developed by Mozi and the "Three Confusion Theory" proposed by Xunzi.

In particular, Mozi's "Three Tables Theory" can be said to have directly established the ancient Chinese logic system. The "rational" thinking shining in it was six or seven hundred years earlier than He Yan, the founder of the new school, proposed "rationality".

It's just a pity that after the Qin and Han Dynasties, because the ruling class only respected Confucianism, the development of ancient Chinese logic system was directly restricted by political and ethical thoughts. In its long development, it has basically been within the scope of epistemology and has not been independent from it.

Become a new discipline.

The most terrible thing is that the ancient Chinese logic system was born out of "Mingbian". There is a mixture or confusion in the understanding of logical properties and language attributes, which can easily lead to linguistic ambiguity and logical confusion. This is also the reason why ancient Chinese logic

The important reason why there are no standardized words for learning.

If you want to break away from this framework, you must borrow tools.

Among all tools, the most convenient is undoubtedly "geometry".

The original meaning of "geometry" is "land measurement", and when translated into Chinese, it also means "measuring size", so it is not difficult for He Yan to let Mi Heng understand this.

In addition, the Chinese ancestors have long left gifts for future generations, and the "Pythagorean Theorem" is a good example.

In order to help Mi Heng better understand and explain "logic", He Yan also opened a huge hook for him——

"Do you know what a coordinate system is?"

He Yan looked into Mi Heng's eyes with a smile.

And Mi Heng's eyes had already been ignited with flames.

This is the fire of civilization thirsting for knowledge!

After sending the crazy Mi Heng to a house in Hewu, He Yan rushed back to Sikong Mansion and coaxed Cao Pi like a child.

"Okay! Let's go out and play!"

"How dare he scold me?"

"Then go to the Nulu?"

"How dare he scold me?"

"Take you to make money?"

"He... hmm? What did He Yanqian say he wanted to take me to do?"

Cao Pi was really small-minded. He Yan persuaded him for nearly half an hour before he finally came to his senses.

But after coming back to his senses, Cao Pi became even more angry.

"Growing up, who dared to scold me? Ah? He actually dared to scold me?"

Hearing Cao Pi's words, He Yan stared at Cao Pi with a strange expression.

Cao Pi was a little embarrassed by He Yan, so he had to add: "Who dares to scold me except dad?"

"..."

"And my mother."

"..."

"And Uncle Ren."

"..."

"And you and Cao Jie..."

Thinking of this, Cao Pi became even more sad.

"Okay, you know how bad Mi Heng's mouth is. Dad has been scolded before, let alone you?"

Cao Pi looked at He Yan with hopeful eyes: "Were you also scolded by Mi Heng?"

"That's not true."

"..."

Cao Pi turned his back and hid in the corner alone, drawing circles wildly.

Seeing that Cao Pi seemed to be really traumatized, He Yan sighed: "Let's go, I'll take you to play."

"Nvlu? Not in the mood today?"

He Yan shook his head: "I'm not a nv, I'm taking you to heaven."

Cao Pi turned around and hesitated for a few seconds, then asked with some uncertainty: "Were you scolding me just now?"

"Who scolded you?"

He Yan rolled up his two sleeves and tied them up, as if he was about to do a big project: "It's really God!"

Cao Pi looked at the blue sky and white clouds outside in confusion: "Heaven?"

"Well, God."

He went over and kicked Cao Pi in the butt. He Yan shouted sharply: "Get up and work!"

Cao Pi followed He Yan outside in confusion and started doing handicrafts with He Yan.

First, a huge piece of fine cloth was taken from the Hewu Textile Factory. This fine cloth was more than ten feet long and five feet wide, enough to make dozens of clothes.

Now this huge piece of cloth was thrown into the yard by He Yan. If those people saw it, He Yan would be impeached for the crime of "waste".

After the cloth was spread out, He Yan bought a few barrels of raw lacquer for applying lacquerware. This is natural sap cut from the lacquer tree. It is resistant to moisture and high temperatures, making it an excellent material.

"Cao Pi, apply all these raw lacquers on the cloth."

He Yan's order made Cao Pi doubt his life: "Paint them all?"

"Well, we need to paint both sides."

"He Yan, I know you are rich now, but that's not how money works..."

The price of raw lacquer was extremely expensive, and Cao Pi was afraid that Cao Cao would get angry when he came back after such a waste.

"You don't have to pay!"

Cao Pi then turned around, excitedly picked up a bucket of raw lacquer and smeared it on the fine cloth.

After all, it was He Yan’s money that was spent! Why do you feel distressed?

"La la la la~"

When Cao Pi thought that He Yan's many five-baht coins would disappear every time he applied it, he applied harder with the brush in his hand, applying the raw lacquer thickly and heavily to every place on the fine cloth.

He Yan himself tinkered with the kerosene ignition device.

That's right, He Yan said he wanted to take Cao Pi to the sky, and the thing he used was actually an enlarged version of the Kongming Lantern - a hot air balloon.

The most difficult thing about a hot air balloon is the balloon material and power fuel.

For the former, even He Yan had no choice but to ask Cao Pi to cover the fine cloth with raw lacquer and wait for as long as it lasted.

It's easy to say that power fuel is good. Kerosene was already popular among the aristocracy during the Han Dynasty. Even though the price is still a bit expensive, for He Yan now, is it expensive?

You know, the first hot air balloon in history used straw as fuel...

Without much effort, a kerosene device was completed.

After that, just ask the tailor to cut the fine cloth covered with raw lacquer into a suitable shape, and then put a light bamboo basket underneath, and this simple "hot air balloon" of the Eastern Han Dynasty is ready.
