In the lecture hall of Guanshishan Academy, there is a special lecture today.

In the past, those who could give lectures in this lecture hall were either bigwigs like Li Kuan and Sun Simiao, or important ministers invited by the academy from the court.

Today, however, is a little different.

Big Ben is not stupid at all! 》

That's the topic of today's lecture.

Needless to say, the speaker must be Lang Qing.

The clock workshop under the Chu Wangfu is now rushing to make Big Ben, and now only one of the finished products is on the Mingde Gate.

However, this does not affect the students of Guanshishan Academy to understand some basic information about Big Ben.

"Senior brother, did you say that the master would come on in person in a moment?"

Liu Yuan and Di Renjie naturally came to the lecture hall today, but they did not sit at the front.

Since Li Kuan also attended today, a bunch of heavyweights in the academy also attended this lecture, and the positions in the front row were the turns of Liu Yuan and Di Renjie.

"I will definitely play, but how long I will play depends on how much Master wants to support this Lang Qing."

Liu Yuan looked at the crowd of people who were still coming in at the entrance of the lecture hall, and looked forward to today's lecture a little more.

Although at the time of construction, this lecture hall was built according to the capacity of more than 1,000 people.

However, looking at the appearance today, it is clear that the number of people who will come in will definitely not be less than 2,000.

At least half of the students of Guanshishan Academy will come to participate.

The other half didn't want to come, but they couldn't squeeze in.

"I went to look at the inside of the watch workshop, and the Big Ben seemed to have a simple dial, but the various parts behind the dial actually contained unpredictable logic. To be honest, it must have taken a lot of effort for Senior Brother Lang to invent this kind of timing mechanism. It is almost inevitable that Master will strongly support this kind of thing. ”

The longer Di Renjie stayed in Guanshishan Academy, the more he read the books in the library of the Chu Palace, and the more he felt that his knowledge was insufficient.

In the past, he thought that he was the smartest person in the world, and when he was very young, he was reluctant to deal with some laypeople.

Now that he has joined Li Kuan's disciples, his temper and conduct have improved a lot.

The harder I work, the more I feel my shortcomings.

"Since the establishment of the academy, Lang Qing is the first student who is qualified to hold such a grand lecture, and his Big Ben is naturally different. Let's listen first, and we'll know the meaning behind this bell in a moment. ”

Liu Yuan saw Xu Jingzong walking towards the podium, and it was obvious that this different lecture was about to begin.

……

"The Big Ben on the Mingde Gate, I guess everyone hasn't seen it and heard it. As a new major achievement launched by our Guanshishan Academy, His Royal Highness the King of Chu has arranged for personnel to set up a special watch workshop, and the Tang Royal Patent Office issued the first patent to Langqing. Therefore, Langqing will take the patent as a shareholder, accounting for 5% of the watch workshop, and this part will never change. ”

As soon as Xu Jingzong came to power, he first brought a blockbuster news to everyone.

Although the students in the academy do not have as strong a sense of money as the people outside, they are not stupid.

In addition, people in ancient times were more precocious, so they had a more thorough understanding of the meaning of money.

And all the clocks produced by this watch workshop will be named Langqing brand clocks, and the name of Langqing will be engraved on each clock. In addition, the academy will hire Lang Qing as the teacher of Gewu Academy, and set up a clock research institute, with Lang Qing as the director. ”

As soon as Xu Jingzong's words came out, there was a buzzing discussion in the audience.

This reward is a bit beyond everyone's expectations.

Even the person concerned, Lang Qing, was a little at a loss and stood on the edge of the podium, not knowing what to do.

Fame and fortune, that's what I'm talking about.

"A year's plan is like a valley of trees; A ten-year plan is like a tree; A lifelong plan is as good as a tree. Whenever I think of the teachings of His Royal Highness the King of Chu, I always have a deeper level of understanding. Guanshishan Academy is a academy that cultivates talents, where everyone's talents will be respected to the greatest extent and create the greatest value for Datang......"

Like the conference in later generations, Xu Jingzong, the actual administrator of Guanshishan Academy, spoke on the stage for a quarter of an hour before coming down.

If Li Kuan hadn't attended the lecture today, maybe he would have been on stage for half an hour.

"Thank you, His Royal Highness the King of Chu, without His Royal Highness the King of Chu, I would not be able to shine today. As an ordinary craftsman's child, the first fifteen years of my life were spent trying hard to fill my stomach, and entering Guanshishan Academy was a major turning point in my life......"

Although Lang Qing is not good at words, but with the manuscript prepared in advance, he is not exempt from vulgar nonsense for a quarter of an hour.

Fortunately, he can still distinguish the weight.

Yesterday, Li Kuan specifically told him about the content of today's lecture.

"I don't dare to boast about how good this Big Ben is, please feel for yourself. Next, I would like to explain that this Big Ben involves the technology that everyone at Gewu Academy is learning or researching. Let everyone have an intuitive understanding of what they are learning for. ”

Lang Qing looked at Li Kuan's position under the stands and started today's lecture.

What is the use of reading?

What is the use of studying at Gewu Academy in particular?

This is a question that has been questioned by many people.

For example, the gravity experiment that Li Kuan did in Gewu Building back then, although it subverted everyone's cognition, but what practical use it was, many people still can't say.

Another example is that the students of Gewu Academy are required to study the courses of the School of Mathematics, which is also something that many people do not understand very well.

Today, these things will be expounded in Langqing's lectures.

"First of all, I want to mention the gears that His Royal Highness the King of Chu told you before. This gear, which seems very simple, actually contains a vast and profound knowledge. To put it mildly, this one cog alone is worth a lifetime of study for many students.

As we all know, Big Ben has three hands, the hour hand, the minute hand and the second hand, and when the second hand rotates around the dial, the minute hand will advance by one stop, and when the minute advances by twelve stops, the clock will also move by one stop. This logic may sound simple, but to achieve it, you need to have a very accurate understanding of the gear ratio. ”

Considering that in addition to the students of Gewu Academy, there are a large number of other students who came to listen to the lecture today, so Langqing tried his best to explain in simple and popular words.

Even when it comes to some difficult points, he will also add some suggested structural diagrams to the blackboard to supplement the explanation.

Even so, he talked about the transmission of a single gear for almost half an hour.

And that's just a few simple principles.

"In addition to this gear, there is another very crucial thing on Big Ben, and that is the pendulum. This pendulum is connected to the gears of the seconds and the clockwork, and is a key device that sets Big Ben in motion. How to set the weight and length of this pendulum is related to the accuracy of our Big Ben, and only by choosing the right ratio can we make our Big Ben as accurate as possible. ”

With Lang Qing's explanation, the students of Gewu Academy had a further understanding of Big Ben.

Because many of the contents of Big Ben have been protected by patents, Langqing has not hidden it at all.

He even took out the core organization diagram and explained it.

Just like that, from morning to noon, when it was close to dinner, Lang Qing walked off the podium.

In the end, it was natural that Li Kuan would go up and say a few words, which was unavoidable.

"As big as your heart, so big your dreams are."

As soon as Li Kuan came to power, he threw out a famous quote to everyone.

"There is nothing impossible that you dare not think. A carriage that can move without a horse, a machine that can beat an iron ingot without manpower, a boat that can walk without a sail, and even a machine that flies like a bird, all of these sound incredible, but do they really not exist, are they really impossible? I don't think so! ”

"Why did Langqing invent such a powerful timekeeping machine, but this king gave it the name of Big Ben? In fact, it is not because of how stupid this bell is, on the contrary, everyone listened to Langqing's lecture, and this bell is more advanced than many things. Our Guanshishan Academy wants to be the best academy in the Tang Dynasty, and it must take some roads that no one else has taken. We can't be like the students of the Guozijian who know it every day. ”

Li Kuan is not afraid of Kong Yingda's opinions on himself if he listens.

Anyway, the relationship between the two families is already very bad now, no matter how bad it is.

Besides, Li Kuan is now raising the banner of "science" in Guanshishan Academy, which is destined to conflict with Confucianism.

He didn't want to destroy Confucianism, but just to change the Tang Dynasty's atmosphere of only recognizing Confucianism as orthodoxy.

Science is the key link, supplemented by Confucianism.

Such a match is still acceptable to Li Kuan.

I've eaten meat, so I can consider a proper portion of soup for you to drink.

"Senior brother, Master deserves to be a Master, dare to say anything. I've been holding this in my heart for a long time, and I haven't dared to say it. ”

Di Renjie sat in the crowd, listening to Li Kuan's speech on the podium, and felt a surge in his heart.

Although his scriptures were also excellent, after entering the Guanshishan Academy to study for a while, he became interested in several other subjects.

I don't know if the prime minister of Datang will become a scientist because of this change.

Liu Yuan: "That's nature, in this world, if there is anyone who is more daring than the master, it can only be the little junior sister." ”

Di Renjie: ......

"Shinong industry and commerce are like people's internal organs, and they can't do without anyone. Although many of the contents of the students of Gewu Academy are considered to be craftsmen's skills, this king does not feel embarrassed at all. Even this king thinks that I am a craftsman myself.

At the beginning, if it weren't for the fact that skilled craftsmen made hot air balloons, how could this king have defeated the 20,000 elites of the Western Turks with more than 1,000 guards? If it weren't for the invention of the craftsmen, how could the official road from Chang'an to Liangzhou and Chang'an to Luoyang be as flat as it is today? ”

Influenced by the continuous development of Qujiang Academy and Weishui Academy, the students of Guanshishan Academy have endured some different pressures in Chang'an City.

Taking this opportunity, Li Kuan simply and directly expressed his views.

"As you all know, we have a magazine in our college called Science. Many people may be curious about why this king chose such a name, compared with the "Yafeng" of the Guozijian, it seems that there is no poetry at all. His Royal Highness the King of Chu, you won't be Jiang Lang's end, right? ”

"Actually, in my king's view, whether it is the Gewu Academy, the Agricultural College, or other colleges such as the School of Medicine, what you study, and the process of your pursuit of truth, is actually a process of scientific exploration. This king attributed the things taught at Guanshishan Academy to science that were different from other academies. Is Confucianism important? ”

When Xu Jingzong heard this, his heart chuckled.

Whether you admit it or not, the current influence of Confucianism is enormous.

If Li Kuanzhen threw Confucianism to the ground and stepped on it with his foot again, the rebound would be too great.

This is not what Xu Jingzong wants to see.

"Confucianism is, of course, important. Kong said that he became benevolent, and Meng said that he took righteousness. Ben Wang never denied the importance of Confucianism. However, can Confucianism alone make the people live a good life? Doesn't it make the farmer's food production higher? Can it make the production efficiency of the workshop higher? Can it make the patient's disease better? The answer is obvious. ”

"Science and technology are an important driving force for social progress, whether it is Big Ben or new things that will appear in the future, it will have a long-term impact on Datang. We should be confident in the system of our college, in the projects we study, and in our future. ”

It took nearly half an hour for Mr. Li Kuan to end this different lecture.

Many years later, when the descendants of Guanshishan Academy took out the minutes of this lecture, they would find that many things were in the dark, and it seemed that the answers could be found in this lecture.

This gives the lecture more historical significance.

Even in the history examination papers of later generations, the time and content of this lecture were taken as a compulsory item.

As the biggest beneficiary of the lecture, Lang Qing naturally became famous in the first battle and became the most famous person in the fourteenth year of Zhenguan in Guanshishan Academy.

As a result, the Watch Institute attracted dozens of students from various faculties to join the Institute as soon as it was founded, and it became the second only research institute after the mechanical workshop.

Of course, Lang Qing is not complacent because of his current achievements.

On the contrary, because Li Kuan proposed many suggestions to him to improve Big Ben, his life became busier.

Even if the Chinese New Year is approaching, the various colleges have begun to have their holidays, and he is still busy in the academy.

Behind every successful person, there is a contribution that everyone can't see.
