Jia Yi has never played with a glider, but he has seen this kind of thing, flying in the sky is very windy, but if it lands, it is very dangerous, as a person who cherishes his own life very much, just thinking about doing something, he will think of all the accidents that will happen to him, for example, when Jia Yi made a kite in a celebrity, he made a parachute by himself......

Tie people to the kite, Jia Yi doesn't know if he can fly, but in later generations, if people want to play with the glider, they must stand on the commanding heights, and then jump off on the glider, without any experiments, Jia Yi did not think of using this very dangerous way, so he was very decisive to give all the equipment on his body to a curious family standing next to him.

"Master Hou, can you let go of the little one." Jia Ding couldn't stop looking at Jia Yi, who was tied to him with various straps, and said to Jia Yi with a bitter face, if Jia Yi hadn't tied a huge kite to him, he would have wanted to kneel down for Jia Yi and beg for mercy.

"Don't worry, if you have a three-game and two-short, I will take care of your family."

Before Jia Yi's words fell, Jia Ding knelt directly on the ground and kowtowed to Jia Yi, which directly caused the kite tied to his back to break a lot of skeletons under his movements, and in desperation, the experiment had already been declared over before it began.

Even the Hou Ye of the Tang Dynasty must not joke with the lives of living people, but the current experimental conditions are very limited, and even if Jia Yi wants to replace something else, there is no way at all, so he can only give up in desperation.

Just when Jia Yi was about to clean up and give up this boring experiment, a little fat man came to the manor.

Seeing this person, Jia suddenly felt a headache, there was just a Li Chengqian in front of him, and now there is another Li Tai, these brothers really regard themselves as their think tanks or what.

In history, Li Chengqian and Li Tai can even be described as good friends, after all, although the two of them are fighting each other, but in the end everything they did was to make wedding dresses for others, although they were not killed by Li Er in the end, but they all ended up depressed, and their thirties were in their prime, but they entered the loess mound, and I have to say that it is a regrettable thing.

In fact, if Li Tai did not compete with Li Chengqian for the throne, then the throne would inevitably become one of the two of them, and it would be completely impossible for it to fall into the hands of others, let alone into the hands of their common younger brother Li Zhi.

"Jia Yi visited the King of Wei, but he didn't know that the King of Wei had arrived, and he hoped to forgive his sins." Jia has learned this kind of official rhetoric a long time ago, and there is no unnaturalness in saying it, and even saluting Li Tai is very standard, so that Li Tai can't find the slightest fault.

Li Tai is conceited, this is for sure, I don't know if he inherited the good genes shared by Li Er and Empress Changsun or for some other reason, this kid has been smart and clever since he was a child, and he is even more obsessed with learning, so that he is already a rich man at a young age, which makes Li Er love him very much.

Li Er's long-term praise has made Li Tai a little unpopular, if it weren't for those Confucians who have been famous for a long time, they basically can't get into his eyes, and today I came to Jia Yi just to ask if the magical arithmetic method I saw by chance was really from Jia Yi's hands.

"Jia Yi, let me ask you, Xin Guangmao and Ma Zhou are said to have learned all the arithmetic from you, from whom did you learn it?"

Li Tai actually doesn't have much affection for people like Jia Yi who are good friends with the crown prince, especially after those under him are provoking him to seize Li Chengqian's position as the crown prince, which makes everyone who is good friends with Li Chengqian have an instinctive disgust, and now he inevitably shows a little arrogant when he speaks.

"It's a family heirloom."

"There's a template, let me see it."

"The template has been lost for many years, but all the records in it are in my mind, if the King of Wei does not give up, I can teach His Royal Highness the King of Wei."

Seeing this, Li Tai knew that it was Sensei who planned to get the template from Jia Yi's hand and study it on his own, although he really didn't want to have too much contact with Jia Yi, but in order to be able to learn this magical arithmetic, he was still ready to study behind Jia Yi for a while, the reason why he didn't go to Ma Zhou or Xin Guangmao was because they all belonged to different camps and couldn't speak, and people also knew that they cherished the broom, and this kind of thing was not a real thing, and it was impossible to grab it, if people didn't want to teach, you would even put a knife on someone's neck, people won't reveal half a word.

Arithmetic from elementary school to high school is really not difficult for Jia Yi, and he has taught it to many people, although there is no guarantee that they can all understand it, and he can be sure that they have been able to use mathematics correctly.

Now that Li Tai has come to study, Jia Yi doesn't have to guess and knows that this is Li Tai's hope that he can take his knowledge to the next level through learning, and it is good that when the time comes, he will have more things to write when compiling the "Tuo Di Zhi", anyway, it is no longer a secret, so Jia Yi no longer has the need to hide it, and directly told Li Tai everything he has learned, and compiled it into a book according to Li Tai's requirements for him to study at any time.

If mathematics is only systematically learned, it is actually very simple, nothing more than addition, subtraction, multiplication and division, there is nothing difficult to learn at all, but if you study mathematics, it will be too difficult, for example, Jia Yi called Li Tai multiple equations, which made Li Tai fall into contemplation, and for several days he did not go out of the door, just thinking about this problem, but he couldn't think of how to solve it anyway.

As a real person, it is very necessary to go to school to be literate, at least under the premise of literacy, people can not be confused by words, but to say how many things that have been learned in school have a role in real life, it is very difficult to say, daily life and work basically do not use any of the same in biophysical chemistry, the most commonly used is the Chinese text and mathematical algorithms, so, although Jia Yi has several students, but what he really teaches is only the most practical part, As for the things that were of little use, he didn't even think to teach them.

But as Li Tai, who is a top student, even if Jia Yi deliberately picked out all the things that didn't have much effect, he would still keep asking Jia Yi until Jia Yi answered all the questions he wanted to know one by one.

It's just that in this way, the problem comes again, the knowledge that Li Tai wants to know is coherent, and if he learns this, he must learn another, otherwise, he doesn't know how to solve the problem he is doing now.

Unconsciously, Li Tai fell into this kind of crazy study and couldn't extricate himself, and as for what his subordinates told him about stumbling with the prince or confronting the prince, he was directly left behind.

Invisibly, Jia Yi completely tied Li Tai to the general knowledge of the ocean, and he had no other mind to take care of other things, without Li Tai's trouble, Li Chengqian would be much better, no matter what kind of performance he had when he was an official, no one would stand up and pick his nose and eyes.

Although Li Tai's subordinates are all firm in this belief, without Li Tai as their backbone, even if they think of a very perfect plan, they can only put it on the table and accumulate dust, which is useless.

Three months of study made Li Tai completely fall into a crazy touch, the new knowledge of mechanics made him fall into it and couldn't extricate himself, the phenomenon that he didn't care about before is now able to attract his very big attention, such as the kettle placed on the stove that Jia Yi asked him to pay attention to, and the lid of the kettle will not stop jumping after the water is boiling.

Jia Yi has no doubt that if Li Tai persists, he will definitely be able to discover the prototype of the steam engine from the kettle, in just three months of study, Li Tai not only mastered all the mathematics before high school, even the physics problems proposed by Jia Yi began to be able to solve independently, looking at problems from different angles or thinking about problems can always bring people great joy.

In the past, Li Tai would only seriously carry out detailed calculations on the problem of chickens and rabbits in the same cage, and then launch the final correct result, but now under Jia Yi's intentional teaching, Li Tai's first reaction after hearing such a question was to hit the person who asked such a question, and then roared: "Can chicken paws and rabbit legs be the same, just count them directly, and count them as a gross calculation." ”

See, this is the progress of the mind, after taking oneself out of the thinking pattern, a pair of eyes can see a lot of unusual surroundings.

At the beginning, Li Chengqian was afraid that Jia Yi would rebel and help Li Tai, when he saw Li Tai sitting on the chair like a mad demon calculating the equation that he didn't know what to do, Li Chengqian's heart relaxed, Li Tai maintained such an attitude very well, he liked it very much, because if he continued to develop in the way arranged by Jia Yi, Li Tai would inevitably become an old scholar in the end, but there was no possibility of competing with him for the throne of the emperor.

Sometimes learning knowledge is not necessarily a good thing if you are crazy, and even sometimes learning will be a kind of undoing business, too much learning takes up his time to do business, compared to the princes, learning is not not doing business.
