As a doctor, it is not uncommon for patients to secretly eat some food that does not conform to the concept of nutritional medicine in the ward.

In this regard, veteran doctors generally stop it with a straight face, but there are also some experienced doctors who just tell the other party that enough is enough.

At least Cheng Chubi agrees with the second statement. My beloved wife has given birth to a child exhaustedly, and her mouth is so greedy, what's wrong with eating and drinking? Shouldn't you enjoy it?

Looking at Li Mingda and Wu Meiniang in front of them, and those who were curled up in their swaddling clothes at the moment. Cheng Chubi glanced at the five people in front of him, raised his chin towards Deng Chengxin and said. "Go, get a jug of water."

After a short time, a pot of water was brought over, and Cheng Chubi began to pour water into the thin-necked porcelain bottle vigorously.

And those few seemingly slender wooden sticks did not break even when the thin-necked porcelain bottle was filled with water.

The porcelain vase was still hanging in the air, motionless, Li Ke stared blankly at this scene, and then muttered for a long time.

"This, this is impossible at all, this must be some kind of fairy art, or there is something wrong with these sticks of yours..."

Hearing this guy's feudal superstition, Cheng Chubi couldn't help rolling his eyes.

He picked up the porcelain bottle filled with water, and handed a wooden stick in it to Li Ke.

Li Ke took the thin wooden stick with a little force, and with a click, the wooden stick broke directly...

"How about letting someone try?" Shangguanyi couldn't help asking with itchy hands.

Shangguanyi has a good memory, memorized the operation steps of Deng Xinxin just now, and accomplished a feat of hanging a porcelain bottle full of water from three small wooden sticks in a short amount of time. .

"This, this is physics?" Li Ke shook his head in disbelief, feeling that the picture in front of him had refreshed his cognition.

"Yes, this is the mechanics in physics. Many forces acting on the same object are called force systems."

"Under the action of a system of forces, an object maintains a state of balance, and this force is called a system of balanced forces.

To put it simply, these three seemingly fragile sticks rely on the application of mechanics..."

"The stretched rope gave the second wooden stick enough squeezing force to ensure the friction between the rope and the wooden stick, and the three wooden sticks formed a stable triangular structure.

And it has reached a state of force balance. Therefore, as long as you find the point of force, you can easily lift the porcelain bottle filled with water. "

"There is a lot of physics involved here, so I don't need to explain it anymore, mainly because it will be more complicated for you."

Cheng Chubi's words made Li Ke and Li Ke's faces not very good-looking, but they couldn't say anything to refute.

"Let me give you another simple example. For example, the tea soup in our tea bowl is mainly composed of water, and water has three physical forms."

"One is in a liquid state, like the tea soup we can drink, and the other is in a gaseous state.

You must have also seen that the white air rising above the hot tea soup, you only need to cover it with your hand, and the water vapor will condense on your hand. "

"There is also ice and snow that we see in winter, which is another physical form of water, called solid state."

"How dare you ask Cheng Taichang, what is this chemistry?" Xin Mao will look at the next subject, which is the word chemistry.

"Chemistry may seem a bit abstract to you, so I will give you two simplest examples.

One is combustion, what will be produced by burning wood, light and heat, this is a chemical reaction.

Also, the soap I gave you before, do you know what it is made of? "

Gu Yu

"The fat is used. If the fat is to be turned into soap, it needs to be soaped, and saponification is also a chemical application."

Cheng Chubi talked eloquently there, and gave vivid examples, so that the group of imperial examination talents and Li Ke had a general understanding of the differences between various subjects such as chemistry, physics, and nature.

But after hearing this, Li Ke couldn't help asking his own questions.

"What's the use of learning these things?"

"Hehe... Brother, you are very good at this question, let me tell you this, the house we live in.

Whether it can be strong and reliable enough involves the principles of physics. "

"Also, do you still remember the printing machine that I made for my brother.

There are a lot of physical principles involved, so that it can far exceed the efficiency of manual printing. "

"As for chemistry, it's even simpler. Without soap, can you be so white and fragrant? And why metal rusts, this is also a chemical reaction..."

"In addition, mathematics is the foundation of all of this. Whether we are doing business or building buildings, we must use it."

"To give the simplest example, just like the range of our Datang's bows and ballistas, it can also be calculated using physics and mathematics."

Cheng Chubi was eloquent, showing off his talents with spittle, which was naturally due to the fact that he was a medical student.

At that time, it was because I was strong in science and my foundation in liberal arts was a bit poor, so I couldn't study Chinese medicine.

However, this allowed Cheng Chubi to be proficient in modern medical skills, at least mathematics, physics and chemistry were not neglected.

On the afternoon of the 16th day of the eighth month in the mid-autumn festival of the tenth year of Zhenguan, Cheng Chubi, several young talents and Wu Wang Li Ke.

A small-scale scientific knowledge popularization seminar was held in his small courtyard of Duke Lu's mansion.

At the meeting, Cheng Chubi, an outrageously knowledgeable Tang talent, used a lively teaching method.

Let them understand that their level of knowledge is nothing compared to Cheng Taichang.

Importantly, Cheng Chubi also linked the application of various disciplines with daily production and life.

Let them understand how helpful these subjects are to daily production and life.

It was heard that they had a feeling that they had seen him through and thoroughly understood how powerful he was.

In the end you realize that ~lightnovelpub.net~ your previous understanding of him was so superficial and one-sided.

The five people sat in the room dumbfounded, and at this moment, Cheng Chubi stood with his back to the door, spit saliva in high spirits.

The evening sunlight, through the wide open door, hit Cheng Chubi's back.

The five of them seem to have seen a sage bathed in the sun, with golden brilliance all over his body...

It turns out that everything in the world, when it comes to Cheng Chubi's mouth, will become a reason that can be explained in a framed manner.

It seems to have opened a new door for them, letting them understand that many things they have seen, seen, and even used.

There are many disciplines in it, but ordinary people are just groping and trying.

But they have never considered the truth behind things. describe.
