But Hong Tao's purpose is much more than that, calculating the volume of a sphere will use Arabic numerals, pi formulas, cubic formulas, as well as the concepts of density and volume.

Each of these calculation ideas, calculation formulas, and concepts can be taken out and broken down separately and verified mathematically. In order to verify this, more calculation methods, formulas and new concepts are needed. More methods, formulas and new concepts can be verified......

The cycle repeats, and eventually a problem will evolve into countless problems, which can involve almost all the formulas and concepts of algebra and geometry before high school in later generations.

Push back!

This is Hong Tao's conspiracy, he dug a huge pit for the teachers and students in the academy, if anyone falls into this pit, it is difficult to say whether he can climb up in this life. And there will be no complaints, all willingly jumping into the pit, and I have to thank the initiator Hong Tao a thousand times.

In a step-by-step way, teaching ancient college students slowly from the preschool curriculum is basically unreliable. Not to mention whether they are willing to listen to their daily nonsense, it is difficult to obtain the right to speak in the vernacular.

Didn't I say it earlier, even if I am a doctor of the Mathematics Academy, I still can't teach separately, I have to follow the syllabus of the Computing Academy. If only Hong Tao could understand those ancient arithmetic books, the problem is that he can't understand them at all, so he can't mix them with the concept of the afterlife.

So Hong Tao changed his approach, first let everyone see the results, arouse interest, and then explain why step by step. For these college students, step-by-step, step-by-step learning is not necessarily the best way, but it may be better to arouse their curiosity and let them find the answers on their own.

"This method is very second, so wonderful! Mr. said that zero should be derived from Tianzhu Mahayana Buddhism, take its gods and demons are not exempt from the phase, can not get rid of the suffering of reincarnation, there is nothing, there is nothing, there is no existence, the origin is also ...... "Needless to say, the effect will come immediately, someone responded to Hong Tao's way of solving the problem.

Hong Tao does not have his own professional courses in the academy, so naturally there will be no classes, and the place where he lectures is a forest of steles behind the courtyard.

Not only was the country eunuch changed from a temple, but the predecessor of the arithmetic courtyard was also a temple, and it was not clear what Hongtao was written on these stone tablets before, and now it is written with numbers and formulas, all thanks to the ink derivatives in his hand, which is black.

Don't look at the class, there are quite a few people attending the class, more than 20. At first, there weren't so many, but while talking, someone quietly slipped back to call people, wanting to break the mad horse's demon law with the strength of the crowd, and the more people gathered, the more people gathered.

The one who spoke was obviously also called from behind, and he kept standing in the outer circle and watching. As soon as the words came out, everyone showed him left and right, it was a thin middle-aged man, not tall, with a green robe, a green hat, black boots, and three strands of long hair.

"This word does come from Tianzhu, Your Excellency is ......"

Hearing what this person said, Hong Tao chuckled in his heart, could it be that he met a traverser again? Otherwise how would he know that Arabic numerals were not invented by the Arabs and that the real masters were in India.

"After entering Shen Kuo, I saw that Mr. was very wonderful, so I disturbed him, and I looked at Haihan." Seeing that Hong Tao's face became solemn, the person who came hugged his fists and gave a salute, apologizing, thinking that he had disturbed the lecture by talking too much.

"Shen Cunzhong?" Hearing this name, Hong Tao was first relieved, and then shocked. Another bull, compared to Wang Anshi, Shenzong, Sima Guang, Li Gonglin, including Su Shi, this one seems to be more powerful.

Those people are playing false, but this one is real. He has made achievements in astronomy and geography, mathematics and physics, and chemical smelting, and has also written medical skills and musical scores.

What made Hong Tao wonder the most was that Shen Kuo had also sent an envoy to the Liao State and completed a diplomatic mission very well, and this time he was recalled from the Western Xia border as an army commander. How did he achieve both arts and sciences, and be able to write and martial arts?

"It is the petty official, who has heard that the captain has been seriously injured when he returns to Beijing this time, and although his life is fine, he has no memory due to madness, behaves strangely, and is proficient in mathematics. Originally, I thought it was deliberately arranged by a boring person, but after seeing the abacus, I realized that this matter was not a lie. Today, I am fortunate to hear that Mr. solved the problem, it is really wonderful, wonderful! ”

Hearing the horse shouting his name, Shen Kuo was not surprised, and was still explaining why he suddenly appeared in the calculation courtyard, trying his best to avoid a reputation of eavesdropping and stealing learning.

"Hey, hey, hey...... The small skill of carving insects is not worth mentioning...... That's all for today, and we'll continue another day. Come on, Brother Shen, first come with me to see something that needs more praise. Wasp, let Lord Shen use your horse first. ”

How Shen Kuo came here and why he came, Hong Tao was not interested in knowing. I had long wanted to meet this all-rounder, but unfortunately he was sent by the emperor to the Western Xia border to lead troops. It should be because of himself, and the emperor did not plan to use troops against Western Xia, so he was transferred back.

According to Wang Anshi, Shen Kuo should arrive in Beijing before the winter, but unfortunately the sky is not as good as the people, and the first snow fell in the northwest before the winter, which was not small, delaying the trip.

But it doesn't matter, as long as I can see it, I have a lot of things I want to discuss with this all-rounder. There are probably not many people in this world who can understand their own thoughts, and he should be one of them.

What are you doing in such a hurry to pull Shen Kuo back to the house? Without it, look at the printing press.

This thing is quite a headache for Hong Tao, even if everyone, including the emperor and the prime minister, used the excuse of coming to play in the horse mansion, and gave a very positive affirmation after secretly checking it, Hong Tao himself really couldn't bear to look directly at the few things that were put together with broken wooden boards. It's even more embarrassing to call it a machine, the appearance is too simple, the operation is too troublesome, and the efficiency is too low.

There are ways to improve it, but none of them are quite realistic. What Hong Tao can come up with in his mind is nothing more than the modernization and improvement plan of steel and iron bones with lead screw gears.

However, almost every part is cross-era, and it is impossible to improve the smelting, forging, machining, and heat treatment processes at this time by a few grades. If you don't do it, you have to put the chemical industry on the agenda, which cannot be done overnight, and it is not something that can be decided by a colt.

Isn't that something that can't be improved? No, the royal craftsmen led by Peng Da have been working hard to improve, but due to limited knowledge and time, they have no energy or ability to make more improvements. It is nothing more than replacing the original miscellaneous wood with some hardwood materials, which is a little more delicate, but there is still a pile of broken wood in the bones.

Shen Kuo's appearance gave Hong Tao hope. He was a man of his time, and he was very accomplished in the mechanical manufacturing of this era, and at the same time he had sufficient theoretical knowledge and was keen on it, so he was the best candidate to improve and perfect the printing press.

Moreover, in the future, you will need more machinery and equipment to refine white wax and flower paste, and if you can attract this person to be a part-time assistant, you will definitely benefit a lot.
