Chapter 237: Li Chunfeng's technological dream is over)
They studied this QR code for a long time, but they still didn't understand what it was.
In the end, they gave up research on QR codes.
Li An said thoughtfully: "We must learn from the mistakes of the past and learn from the mistakes of the past. We must make anti-counterfeiting signs."
Their family, during the gambling activities of His Royal Highness the Prince of Liang, had all thought of confusing the real with the fake and overthrowing the Prince of Liang. Well, they have now been renamed the King of Shu.
Therefore, when they do it, they must block this point.
However, several of their major families have skilled craftsmen, so designing some complex patterns is definitely not a problem.
I believe that no one will be able to crack it in a short period of time.
At this time, Wang Gui couldn't help but said: "We can print 10 million lottery tickets first to test the heat. But, do you have any suggestions for setting up the grand prize?"
The grand prize must be set. Without the grand prize, it will definitely not attract so many people to come and buy lottery tickets.
But if there are more jackpots, they will earn relatively less.
As a result, Lu Yong chuckled and said: "I think, like King Shu, we will set up three first prizes, ten second prizes, fifty third prizes, one hundred fourth prizes, and three fifth prizes.
One hundred people, one thousand people for the sixth prize.”
"But we will take out the second, second and third prizes separately and not put them in the lottery box. When the time comes, our people will hold these prizes for the lottery."
This Lu Yong was even more ruthless. Not only did he not give away the first and second prizes, he even refused to give away the third prize.
However, this is also in line with the image of the aristocratic family that eats people without spitting out their bones.
…
On this day, when Li Min was resting at home, Yan Liben came to look for Li Min.
This time, Yan Liben not only came to return teaching materials, he also brought a drawing.
This drawing is the layout of a new city he designed himself.
"Master, this is my apprentice's design. Please give me your advice."
After such a long period of study, Yan Liben has learned to use three-dimensional graphics to draw drawings.
After Li Min opened it, he found that the design was very beautiful.
There are even many modern urban design concepts in it.
Well, the textbook he originally studied contained many modern concepts.
After seeing Yan Liben's design drawings, Li Min was quite satisfied.
However, Yan Liben still has historical limitations after all!
For example, how can a city be without parks?
There must be places for leisure and entertainment!
Also, the road is too narrow and must be widened.
There are others, but they are not satisfactory.
And when Li Min pointed out his shortcomings, Yan Liben couldn't help but nodded thoughtfully.
At the same time, Yan Liben's admiration for Li Min was even greater.
The master is indeed a master. This design drawing took me a long time to design, and I thought it was foolproof.
But the master just took a few casual glances and picked out so many problems and gave so many pertinent suggestions.
At that moment, Yan Liben immediately started revising it in the study.
At this time, another of Li Min's apprentices, Li Chunfeng, and his former arithmetic teacher Wang Xiaotong came together.
These two people actually became good friends in this short period of time because of their new arithmetic.
Li Chunfeng is very talented and has made rapid progress in physics and chemistry.
But in terms of arithmetic, he was far behind Wang Xiaotong.
This made Li Chunfeng admire Wang Xiaotong very much.
As everyone knows, Wang Xiaotong admires Li Chunfeng even more.
Because although Li Chunfeng was slightly inferior to him in arithmetic, in other aspects, he was miles ahead of him.
In Li Chunfeng, Wang Xiaotong saw the possibility of practical application of new mathematics.
Therefore, in just a short journey, Li Chunfeng and Wang Xiaotong became close friends.
After arriving in front of Li Min, Li Chunfeng asked Li Min a question: "Master, I wonder how we can make the small plane you showed us the other day?"
airplane?
Seeing the confused looks in Wang Xiaotong and Yan Liben's eyes, Li Min had to take out the model airplane from the room again and let the airplane fly around in the sky.
After the plane landed, Yan Liben and Wang Xiaotong were shocked beyond measure.
Well, okay, most people who see it for the first time have this expression.
Now, even Yan Liben and Wang Xiaotong are deeply attracted.
You know, Yan Liben is a master of architecture, but at the same time, he is good at production, and his talents are not limited to architecture.
Seeing the expressions of the three people, Li Min suddenly had an idea and said: "Have you seen it? When science develops to its extreme, it will be able to create things that can only be imagined in dreams. How big the heart is, how big the stage is."
"Like an airplane, it involves physics, chemistry, mathematics, materials science, mechanics and other scientific knowledge. It cannot be made in a short time. Of course, as long as you study hard and accumulate over time, sooner or later you will be able to make a real airplane.
The plane is coming."
Li Chunfeng asked without giving up: "Master, can I make that kind of small plane now?!"
After hearing Li Chunfeng's words, Li Min couldn't help but have black lines in his head.
Do you think this little plane is so easy to make?
The technological content here is not small at all.
Don't look at the price of toy airplanes in later generations, but the technological content inside is quite high.
Want to make a toy airplane in Datang?
This is really too difficult.
However, Li Min was not willing to dampen Li Chunfeng's enthusiasm.
Suddenly, Li Min thought of a way and couldn't help but said to Li Chunfeng: "Chunfeng, the food must be eaten one bite at a time, and the road must be walked step by step! In this way, before making an airplane, you should first study the problem of train tracks."
train track?
Li Chunfeng couldn't help but asked curiously: "Master, what is a train track?"
Li Min smiled and explained: "The train track is actually a kind of steam locomotive. It can pull tens of millions of kilograms of goods and speed automatically. However, because it is too heavy, there is no way for it to walk on ordinary roads.
.”
"Therefore, we can only lay rails and let them run on the rails. You can imagine, if this rail needs to be laid, what type of rail will be used? What are its stress points? How should it be laid?
?”
After finishing speaking, Li Min was afraid that they would not understand, so he even drew a model of a train and rails.
Li Chunfeng, Wang Xiaotong and Yan Liben were all shocked beyond measure after seeing the model drawn by Li Min.
These three people instinctively felt that since the prince had drawn the model, it proved that this kind of steam locomotive could be actually manufactured.
