Cheng Chubi glanced over the five people in front of him and nodded towards Deng Chengxin. "Go, get a pitcher of water."

With little effort, a pot of water was brought over, and Cheng Chubi began to pour water vigorously into the slender-necked porcelain bottle.

And those small wooden sticks, which seemed to be very slender, did not break until the slender-necked porcelain bottle was filled with water.

The porcelain bottle was still hanging motionless in the air. Li Ke watched this scene in a daze, before murmured for a long time.

"This, it's impossible, this must be some kind of magic, or there is something wrong with your wooden sticks..."

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

Copy the porcelain bottle filled with water, and handed one of the wooden sticks to Li Ke.

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

"How about letting a try?" Shangguanyi couldn't help but ask with itchy hands.

Shangguanyi has a good memory. He remembered the steps that Cai Deng liked just now. With little effort, he also completed the feat of hanging three small wooden sticks full of water porcelain bottles.

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

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

"The object maintains a balanced state under the action of a force system, and this force is called a balanced force system.

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 the state of force balance is reached. Therefore, only by finding the exact point of force, the porcelain bottle filled with water can be easily lifted. "

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

Cheng Chubi's remarks made the imperial examination talents and even Li Ke look unsightly, but they couldn't say anything to refute.

"Let me give another simplest example, for example, the tea soup in our tea bowl. Its main ingredient is water, and water has three physical forms."

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

You must have seen the rising white gas above the hot tea soup. You only need to cover it slightly with your hands, and the water vapor will condense on your hands. "

"There is also the ice and snow 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, that is, the word chemistry.

"Chemistry, for you, may be a bit abstract, I will give you two simplest examples.

One is burning. What happens when wood burns, light and heat, is a chemical reaction.

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

"Fat is used. To turn fat into soap requires soap, and saponification is also a chemical application."

Cheng Chubi talked about there and gave vivid examples to give this group of imperial examination talents and Li Ke a general understanding of the differences in various disciplines such as chemistry, physics, and nature.

But after hearing this, Li Ke couldn't help but raise his own question.

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

"Hehe...Xian brother, you are very good at this question, so I will tell you the house where we live.

Whether it is strong and reliable enough, the principles of physics are involved here. "

"Besides, you can still remember the printing machine I built for my brother.

There are a lot of physics principles involved, which can far exceed the efficiency of manual printing. "

"As for chemistry, it's even simpler. Without soap, can you make it so white and scented? And why does metal rust? This is also a chemical reaction..."

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

"For the simplest example, the range of our Datang bows and arrows and ballistas can also be calculated using physics and mathematics."

Cheng Chubi was eloquent, and Spit Xingzi showed off his talents. Naturally, he was a medical student.

Back then, it was because my science was my strong point and my liberal arts background was a bit poor, so I couldn't learn Chinese medicine.

However, while Cheng Chubi is adept at modern medicine, at least mathematics, physics and chemistry have not been pushed down.

On the afternoon of August 16th on the Mid-Autumn Festival of the tenth year of Zhenguan, Cheng Chubi and several young talents and Wu Wang Li Ke.

A small-scale scientific knowledge dissemination seminar was held in his small courtyard of the Lu government.

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

Let them understand that compared with Cheng Taichang, their knowledge level is simply scum.

It is important that ~lightnovelpub.net~Cheng Chubi also links the application of various disciplines to daily production and life.

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

I heard that they felt that they had seen him thoroughly and thoroughly understood how good he was.

In the end, you discovered that the original understanding of him before coming was so superficial and one-sided.

Five people sat in the room dumbfoundedly, and at this moment, Cheng Chubi stood with his back facing the door, spitting stars in a spirited spirit.

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

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

It turned out that everything in the world, inside Cheng Chubi's lips, would become a matter of fact.

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

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

But they have never considered the truth behind things.

"Just like the clothes on our body, whether it is silk thread or cotton linen, each thread needs how thick the diameter is.

Only then can it be woven into a silk that is strong enough and durable, or smooth and thin.

These knowledge can be used to solve problems..."

Li Ke stared at Cheng Chubi blankly, and found with some sadness that Brother Chubi’s knowledge reserve could be described as a vehicle-mounted bucket.
