Jia Huan said: "The length of the hypotenuse is the square root of two, the value is 1.414213, and the decimal behind it is infinite, and there is no repetition. ”

This number can be called an infinite non-cyclic decimal, which is also an irrational number. Princess Alice, I don't know if I'm right? ”

After Jia Huan finished speaking, Princess Alice's face suddenly showed infinite consternation.

She couldn't help but say: "The number one prodigy in Great Xia, as expected, lives up to his reputation, and actually knows infinite non-cyclic decimals." ”

"However, the advancement of arithmetic in my true country is much more than irrational numbers. But I don't know much about arithmetic, so I can't say more. ”

Hearing this, Jia Huan smiled slightly, and said in his heart: Coincidentally, I don't know more about arithmetic than just an irrational number.

I just don't know if you really have studied calculus now? Jia Huan expects that their progress will not be so fast.

And the civil and military of the Manchu Dynasty, when they heard the conversation between the two, they were completely stunned.

This Jia Zhuangyuan, sure enough, is only eight buckets high, and he is rich in five cars!

His poetry is unparalleled, the exam is still powerful, and he knows the real Chinese, that is, he has such an amazing reputation for arithmetic!

This son is so wicked, he can be called a wise and close demon!

Princess Alice couldn't help but say: "Let's not talk about arithmetic, just talk about our country's four-wheeled carriage, you Daxia can't make it." ”

Hearing this, Scholar Cheng suddenly sneered: "The four-wheeled carriage is certainly stable, and it can carry more goods. However, its steering is inconvenient, and it does not have much practicality, and has long been eliminated by my Great Xia. ”

Princess Alice smiled: "No, the four-wheeled carriage made by my True Kingdom has two wheels in the front and two wheels in the back, which can be turned at will and is very flexible. ”

Fan Zhongyu sneered: "Impossible! When pigs fly! All four wheels are fixed to the carriage, front and rear wheels, how is it possible to complete the steering? ”

Princess Alice said with a smile: "You can't build it in Great Xia, but maybe we can't build it in the real country!" ”

"This time we went to Great Xia, and it happened that our True Kingdom sent a gift to His Majesty the Venerable Emperor of Great Xia. The gift was a horse-drawn carriage. ”

"This carriage is now outside the Imperial Palace, and we ask His Majesty the Emperor to allow our people to drive the carriage in."

Chong Kangdi said: "Accurate! ”

Emperor Chongkang gave an order, and soon, a carriage rushed in.

And Chong Kangdi and the others also walked out of the Jinluan Palace, and in front of them, a two-horse carriage was parked.

The carriage was elaborate, with four wheels at the back, and a fully enclosed carriage topped by glittering gold and carved walls with distinctly Western motifs.

The doors and windows of the carriage are not screens, but all of them are made of glass.

From their side, they can see directly to the other side.

In the Great Xia Dynasty, glass was a luxury.

There is a detail in the book of Red Mansions, that is, Jia Rong once borrowed a screen from Wang Xifeng.

Jia Rong invited An, and replied with a smile: "My father sent me to beg my aunt, and last time my uncle and wife gave my aunt the glass kang screen, Ming'er invited an important guest, and sent it with a little swing." ”

You see, if you want to invite an important guest, you have to borrow a glass kang screen.

The glass used in the carriage alone cost a staggering amount of silver.

This Manchu Dynasty civil and military is also a person who has seen treasures, but he is still shocked by the luxury of the carriage in front of him.

But they still couldn't believe that the four-wheeled carriage could really turn freely.

Princess Alice smiled slightly, then she raised her hand and put two fingers in her mouth, whistling mischievously.

The coachman quickly got started, and as he went, he drove the carriage around in a circle.

And then, he began a series of various irregular directional rotation performances.

This four-wheeled carriage, in terms of flexibility, is almost not much different from a two-wheeled carriage.

This scene completely stunned Emperor Chongkang and a cadre of civil and military ministers.

The faces of these people all showed disbelief.

Of course, there is still an individual case in it, Jia Huan showed a faint smile on his face, and he was not half surprised.

Seeing this, Princess Alice couldn't help asking, "Jia Prodigy, don't you wonder why this four-wheeled carriage can be turned so flexibly?" ”

Jia Huan smiled and said: "The steering problem is that the horse drives the movement of the front wheels, and then the front wheels hold back the two wheels to rotate. The three parties contain each other to solve the problem of steering, right? ”

Hearing Jia Huan's answer, Princess Alice couldn't help but say in amazement: "Is Prodigy Jia a prophet?" Whatever you do, can you have a foresight? Even if you encounter something new, can you see through the essence at a glance? ”

Jia Huan smiled: "That's not the case, in fact, in my ancient Great Xia Dynasty, there were similar devices, but they were not used in the carriage. That's why you can see it at a glance. ”

"By the way, Princess Alice, I wonder if you really have developed a steam engine? Also, haven't you thought of replacing wooden wheels with other materials? ”

The carriage that Princess Alice gave to Chong Kanti has tires that are still made of wood.

Seeing this, Jia Huan was also relieved.

This proves that the process of industrial revolution in Zhenzhen is still in its infliminent stage, and for at least thirty or twenty years, it will pose little threat to Great Xia.

Princess Alice asked curiously, "Steam engine?" What is that? I haven't heard the name in our real country, replacing tires with other materials, and we do have this idea. Jia prodigy might as well guess, what materials will we use? ”

Now, Princess Alice has developed a great curiosity about Jia Huan.

This prodigy Jia is so knowledgeable, there seems to be nothing in this world that he doesn't know.

Now she really wants to know, does this Jia prodigy know about this problem?

I only heard Jia Huan say: "Use rubber, right?" I wonder where you've gotten in your research? How long does it take to be ready for use? ”

This time, Princess Alice was completely stunned.

She couldn't help but exclaim, "Wow, Prodigy Jia, are you an omniscient God?" Are you really amazing? You even know that? Have you ever been to our real country? ”

"Prodigy Jia, you're absolutely right, we are indeed going to replace wooden tires with rubber. However, at the moment we are experiencing difficulties and there is no progress for the time being. ”

"I don't know if Prodigy Jia has any good advice?"

I certainly wouldn't suggest it.

Jia Huan smiled and said, "I'm just guessing, I can't give you advice." By the way, I wonder if Princess Alice can give me some fine rubber tree species? ”

Princess Alice smiled, "Of course, who made you my favorite friend?" When I return home, I will definitely have someone bring it to you. ”
