Unlike the classics, which require rote memorization, those books are more like telling stories and reasoning.

Even if everyone can have the opportunity to learn, but what everyone really learns is completely different, the same book, whether you can really become a talent, depends not on how long you have read this book, but how much you understand?

Comprehension can be divided into two parts, innate and acquired, innate refers to talent, and acquired refers to enlightenment and subsequent teaching.

A famous teacher knows how to guide a young child to look at these problems with the right way of thinking, so the status of a famous teacher is very noble.

However, the latest set of books and textbooks triggered by the imperial court, although it also requires a certain amount of understanding, but the audience is broader.

Moreover, these knowledge are very scattered, several disciplines are completely different, and the imperial court does not require everyone to learn, but if you want to learn, you must at least choose one of these disciplines as the main direction of attack.

Of course, before that, there is also the enlightenment stage, after the enlightenment is the preparatory department, which is to study all the content, and then take the exam three years later, and make a delicate choice based on the results and personal interests.

However, this method is a learning routine for the younger generation, and for those who are already one or twenty years old, or even older, their learning is simpler.

Directly choose a book that you are interested in, and then use the wild road to learn, and when you really master this knowledge, you can easily find a decent job, as long as you do a good job, you can let the owner see your ability, a long-term meal ticket is not able to run.

If you are lucky, this kind of person will cause some bloody storms in the market.

But no matter how those bosses compete, there is only one final result, a salary increase to keep people.

Li Jing has an identity and that condition, so he is willing to get in touch with some new things, and what he has come into contact with is also orthodox education, although he doesn't have to sit in the classroom like those elementary school students, but there are also many people from Zhenbei Academy around him, Li Jing just took advantage of the privilege and let them open a small stove for themselves in their free time.

And what interests Li Jing the most is arithmetic.

What is on the market is only elementary arithmetic, although it is not indicated, and Li Jing did not know it in advance.

But when he finished learning, he was still shocked by this, simple addition, subtraction, multiplication and division, algorithm formulas, and those dumbfounded calculations.

Li Jing personally tested it and counted towards the military formation, but in just a dozen seconds, he accurately calculated how many people there were in a military formation, accurate to the individual.

Who said that arithmetic is not used in the military? Now, even if you calculate the number of people in the whole army, the biggest problem is not to calculate, but to point it clearly.

But further on, Li Jing was exposed to medium arithmetic.

Medium arithmetic has nothing to do with elementary arithmetic, but there is a high-level product like parabola, of course, as of now, Li Jing has not figured out what parabola is all about, it is said that there are not many people in the entire Tang Dynasty who really understand this.

"Arithmetic is an indispensable knowledge in daily life, the people calculate the harvest, the merchants sell and buy, and even the normal operation of the government is inseparable from arithmetic, even the army, it is also inseparable from arithmetic. For the people, elementary arithmetic is enough. "Opening Minzhi does not mean that all the knowledge will be released directly at once, even if it is released, Li Yuanji does not have so many goods in his stomach.

In his previous life, Li Yuanji's studies were still very good, and during the entire junior high school period, his grades ranked among the top ten in the school, but because the conditions at home were really not good, he couldn't afford to study at all by relying on his mother alone, and junior high school was a nine-year obligation, and he could still get through it if he endured it, but he had to pay tuition, living expenses, and other miscellaneous expenses in high school, although it was not much.

But in the summer vacation after graduating from junior high school, Li Yuanji, who had already received the admission notice of a key high school, received the news of his mother's accident, and then, Li Yuanji did not report, but followed the villagers to work on the construction site outside, which was six years, and then until he crossed.

Of course, Li Yuanji also studied high school courses on his own, but he didn't finish them, so in this regard, he is really powerless, and it is good to be able to explain part of it clearly.

But even so, as long as you can understand the parabolic principle, understand the calculation method thoroughly, practice diligently, and understand the performance of the artillery itself, it is not difficult to calculate the trajectory.

"Strengthen the army with science and technology, and strengthen the country with science and technology......" Li Yuanji muttered secretly, making Li Jing on the side a little confused.

……

That's what Li Yuanji said, and he did the same.

At the same time, located in the Academy of Sciences in Chang'an.

There is a clear difference between this place and the outside, there are enough forbidden troops here to protect it, and the people here are not free, but the people here are treated very well.

Meat, one meal a day, green vegetables, no matter spring, summer, autumn and winter, green vegetables have never been cut off, the only difference is that you can eat every day in spring, summer and autumn, and it takes two or three days to eat once in winter.

Wine? Beer or liquor, as long as it does not exceed the limit, can be drunk at will, but it must be within the specified time, and it is not allowed to touch the alcohol at other times.

In addition to these, their salaries are also terrifying, of course, each of these people is poor, because their salaries are directly sent to their families outside the Academy of Sciences, which is why they are willing to stay here.

Of course, not being allowed to go out does not mean that family members cannot come in, and the Academy of Sciences has a separate area, and every day off, family members can enter this area to reunite with these 'scientists', but they are not allowed to mention anything about work.

It's not a day off, so it's a busy scene in the Academy.

It's like a vegetable market, it's a bit chaotic, it's not as organized as you might think from the outside, and if you can use an analogy, then you can say without hesitation that this is a pig's nest.

It seems that people who have been engaged in this industry, no matter how good they were before, will be surprisingly lazy when they come here, scattering things, and never tidying them up, but they can always find them out as soon as they need to be used.

Jiang Tian felt that he was about to die, not to be killed, but to be depressed.

After six or seven years of hard work, he once became famous in the court, wearing a nine-grade sesame official, but he entered the Academy of Sciences.

Is Academy of Sciences bad? In the case of a shortage of official positions in the imperial court, it is also a good choice to come to the Academy of Sciences, and there are not so many intrigues here, there is only one way to be promoted, keep learning, keep improving, and then keep coming up with new achievements, and then you can be promoted, it's that simple.

There are technical positions, there are management positions, and technical personnel do not have to worry about being overwhelmed after promotion, because managers will cooperate with you according to your ideas, tell you how to arrange certain things, and even coordinate according to your ideas.

In short, the higher the level of the technical position, the more power it has, and even more people can be mobilized to cooperate with him to complete a certain experiment.

For example, Jiang Tian is like this, he is just a nine-grade sesame official, and he is known as a researcher.

Graduated from Zhenbei Academy, a protégé of the Son of Heaven, but now he is sitting here, looking at the pile of experimental products in front of him, and then using the drawing technique that he has forced himself to learn for two months, he will draw out this pile of experimental products one by one.

'Knock ......'

There was a sharp pain in the back of his head, and the frightened Jiang Tian shivered violently, and hurriedly looked back, revealing a pitiful expression.

"Running away again, why did Lao Tzu bring such a stupid pig-like student as you? Jiang Tian, do you want to be angry with Lao Tzu? A middle-aged man reprimanded Jiang Tian with an angry face.

"Master......" Jiang Tian is aggrieved and can't do it, is he stupid? You must know that in Zhenbei Academy back then, his learning ability was super invincible, not to mention the top ten, it was also the top twenty, if it wasn't for the imperial court not recruiting so many people, I was afraid that I would have become an official a long time ago, do you still need to stay here to draw this picture?

Perhaps, the imperial court should have deliberately picked up a group of people, so that the remaining group of people had no way out, and then let the Academy of Sciences recruit people at this time, and pull in all those with strong learning ability.

"You look at this picture you draw, and this one, which eye of yours looks at it as if it is bent? If you end up auditioning according to your drawings, who is responsible for the problem? The middle-aged man was holding an iron rod in his hand, obviously straight and straight, but Jiang Tian drew some arcs on the drawings, and he couldn't do it, he felt that Jiang Tian might have some problems with his attitude, so he reprimanded him more harshly: "You tell Lao Tzu directly, do you want to stay here?" If you are willing, you can do it well, if you are unwilling, go and pack up your things now and get out, the provincial Lao Tzu will see that you are angry. ”

"Don't mind, master, the apprentice must do a good job, change! This is changed! Promise not to make the same mistake again in the future. Jiang Tian trembled violently with fright, and hurriedly took out a ruler to draw again, this time his mental power was more concentrated than ever.

Although the Academy of Sciences is not good at the Academy of Sciences, Jiang Tian still likes it here, although the masters are more strict, slapping the table and scolding people are all pediatrics, and even sometimes they can directly chase the apprentice with a stick.

But strict is strict, in the place where the teaching, the masters will never have reservations, those are really good things, real materials, as long as you can become a teacher, and you don't die, whether you can be better than the master is unknown, but at least it will not be much worse than the master.

"Lao Xu, you are trying to make a few of our old guys die of shame......" After the middle-aged man left, several people outside the house were envious, and they looked at the middle-aged man with contempt.

"Hmph, this kid is the kind who doesn't let go and retreats, what's there to be ashamed of? It's a good apprentice in the hands of a few of you. Lao Xu smiled.

"Why don't we change it?"

"Change your fart, put away your little thoughts, just rely on your crooked melons and cracked dates and still want to deceive Lao Tzu? No way......"
