Dreaming about the world, embarking on the path of spiritual practice

Chapter 31 The Wisdom of the Ancients

……

Plunging headlong into the sea of ​​books, Yu Liang crazily absorbed all kinds of knowledge!
Martial arts, biology, physics, medicine, yoga, Internet...

Every time I gain a little bit of knowledge, I feel a sense of accomplishment.

Thinking of the hard study in the past, I didn't gain as much as I did in just a few days. In addition to feeling sad, I felt more satisfied and proud.

It was another bright morning.

Yu Liang opened the door for business as usual.

Lying on the chair, playing with the mobile phone in his hand, his ears listened to the sound of artificial intelligence reading books from the computer speakers.

This is a new ability that Yu Liang has recently discovered: multitasking!
Listening to artificial intelligence reading in your ears and playing with your mobile phone in your hands, you can have fun and learn at the same time.

Even when exercising, I also wear sports headphones.

Perhaps because of his improved physical fitness, Yu Liang didn't feel dizzy or heavy even if he read for a whole day.

So except when sleeping, he was absorbing knowledge from books all the time.

Yu Liang scrolled through the short videos on his phone.

These short videos can not only make you laugh.

Sometimes short video content can also help him increase some strange knowledge.

For example, this short video that Yu Liang is watching now is about introducing a magical antique: a light-transmitting bronze mirror!

The translucent bronze mirror is a bronze mirror from the Western Han Dynasty. It is made by a special process.

The front is as smooth as a mirror. When it reflects sunlight or flat light, the light and shadow of the bronze mirror will reflect the inscriptions and patterns cast on the back of the bronze mirror.

This craft has been lost since the Han Dynasty, so translucent bronze mirrors have become rare treasures since then.

It was not until modern scientists finally figured out the secret after several explorations.

The principle of light-transmitting copper mirror is based on the special properties of copper and the principle of reflection and refraction of light.

Copper is a good conductor and can transfer electricity and heat very quickly.

At the same time, copper is also a good reflective material that can reflect light back.

These properties make copper an ideal material for making light-transmitting copper mirrors.

During the casting process, the concave and convex patterns on the back of the mirror have different thicknesses, which cause casting stress due to solidification shrinkage. After casting, grinding produces compressive stress, thus forming elastic deformation in physical properties.

When polished to a certain extent, the superposition of elastic deformation creates corresponding curvatures between the mirror surface and the pattern on the mirror back, which are invisible to the naked eye.

Therefore, when light shines on a mirror, what the naked eye sees is that the light shines on a smooth mirror surface.

In fact, light shines on textures with different curvatures, and different reflected light appears, so the bronze mirror projects patterns.

This is the principle of light transmitting mirror!

After watching all the content in the short video, Yu Liang was filled with emotion.

Unexpectedly, craftsmen during the Han Dynasty thousands of years ago already had such superb forging techniques.

Even in modern times, without the help of precision instruments, it is extremely difficult to reproduce even if one knows the process principles.

give a like!
Since Yu Liang likes to watch such short videos, the big data system recommends more such short videos to him.

Bronze dragon wash basin, when the basin is filled with water and the basin handle is rubbed with hand, the water in the basin will jump.

The principle is resonance!
When your hands rub the handles on both sides of the copper basin, the basin wall will produce self-excited vibrations.

This vibration propagates on the water surface and is superimposed with the reflected wave reflected from the basin wall to form a two-dimensional column wave to store energy.

Those water droplets with relatively high energy will jump up, forming a fountain-like effect.

Yu Liang had to admire the wisdom of the ancient working people.

They have conducted in-depth research on the refraction of light, vibration of matter and other knowledge as early as thousands of years ago.

Otherwise, we would not be able to create items with natural laws such as translucent bronze mirrors and bronze dragon wash basins.

Just when Yu Liang continued to scroll through the small screen

Suddenly a voice came from the door: "Boss Yu's business is booming!"

Looking up, I saw a man striding over with a smile.

"Hey, isn't this Brother Hao? Long time no see. Where have you made a fortune recently?"

The visitor is Pan Hao, Yu Liang's high school classmate, who is bold and cheerful.But everything else is good, but there is one biggest drawback: I like to play two games!

"I haven't made a fortune. I was practicing in seclusion some time ago, so I haven't come to your place. Today I have achieved success and I will come to your place immediately!"

Listening to his joke, Yu Liang smiled and replied: "You are practicing in seclusion. What kind of seclusion are you doing? What kind of practice are you doing?"

"You can't be recharging your energy to come out today!"

"Damn it!"

After a few jokes

Pan Haocai entered the topic and told the reason why he came here today.

"Boss Yu, please help me!"

Seeing the other party's despicable expression, Yu Liang's expression changed, and he secretly thought that the other party really did not go to the Three Treasures Hall for any reason.

"What's the matter? Let's talk first!"

"Hey, borrow some money!"

"no!"

When he heard about borrowing money, Yu Liang refused directly. He didn't even need to guess, he knew what the other party was borrowing money for.

"Don't worry, I will pay you back the money I borrowed from you tomorrow. Besides, I can put my phone here."

Watching the other party take pictures of his cell phone on the table.

Yu Liang only felt that he was hopeless.

He sighed and said, "Stop playing around. Calculate how much money you have thrown into it in the past few years?"

Pan Hao shook his head slightly and said, "This time is different!"

Yu Liang laughed sarcastically: "Oh, what's the difference?"

Pan Hao replied calmly: "Not knowing the result is gambling, knowing the result is investment!"

"What do you mean?" Yu Liang showed a puzzled expression.

Pan Hao smiled mysteriously, reached out and took out three dice from his pocket, held them in the palm of his hand, and asked Yu Liang to look at them carefully.

"Alright!"

"Three six!"

Three dice were thrown on the table, and after flipping a few times, they finally settled on the number [-].

"cut!"

Yu Liang smiled and said: "Two or six people raise a unit, is this what you call investment?"

Pan Hao smiled awkwardly and picked up the three dice on the table.

"Mistake, it was a mistake just now, try again!"

"Three sixes, Leopard!"

Throw it again and the dice falls on the table. After rolling, the top number is really three sixes!
"Come again!"

"four, five, six!"

Pan Hao threw it again, and the number that appeared on the dice was the same as what he shouted, it was really four, five, six.

"One, two, three!" "Three units!" "666!" "..."

After demonstrating it several times in a row, Pan Hao fully proved to Yu Liang that it could control the number of dice throws.

He looked at Yu Liang with a proud look on his face and said, "How is it? Isn't it great?"

Yu Liang had no expression on his face and said softly: "Is this the result of your seclusion and practice?"

"Hey, it's not just this!"

Pan Hao took out another deck of playing cards from his pocket.

"Next, I want to show you what real technology is!"
