"Heavenly Bestowed"

"Stop, you can call me teacher in class, you can call me the principal in the schoolyard, if you call me a colt, it will only remind me to hurry home to accompany my wife and children, I don't want to leave them for a moment now." Yang Lin corrected the name of a student, and gestured with his hand for him to continue asking questions.

As he said, at this moment he is reluctant to waste time teaching, his first child Yang Tianyang is already three years old, it is the age of the curious baby, the two fathers and sons asked questions and answers, it can be said that for a whole day, his second child has been in his mother Bai Zhihan's belly for ten months, and is about to give birth, these are extremely important things for Yang Lin, and he is worried about his heart all the time. As for the Tang court, well! The imperial court does not seem to have anything to do with Yang Lin, and he has not received any news of any decrees related to him from the imperial court for three years.

"Teacher, you said that you are our chief science teacher, may I ask if the science teaches the legendary technology?" Which of the corrected students continued to ask with some embarrassment.

"You can say that! I divide all the disciplines into three categories: liberal arts, science, and art, liberal arts can enhance people's ability to express and equip people's minds, and science is to increase people's cognition of the origin of all things in the world, which can arm our hands, and arts, which I regard as an indispensable concoction to soothe or cultivate our souls, and do not belong to a compulsory but very important category of learning. Yang Lin said eloquently.

"Excuse me, teacher, will you teach us how to make such peerless weapons as tank fighting vehicles and steel-potash battleships?" Another student asked, raising his hand.

"Theoretically, you have been learning the technology of making those things since you came into contact with science, but it is not easy to create those things, you must at least work hard to become a college student to barely qualify, and I don't think that the existing tanks and steel battleships in Datang are some peerless artifacts, it is just a garbage product that our first generation of scientific and technological people have reluctantly developed under immature conditions, and more advanced and powerful equipment in the future will be created from your hands." Yang Lin replied. Even if he said it calmly, it made the students exclaim.

"The teacher actually said that the tanks and steel giants that are feared by foreigners are junk products, and we will make equipment that is more powerful than tank tanks."

I have to say that Yang Lin's few words aroused the emotions of all students studying science, especially those foreign students who paid a great price to get a place to study in Chang'an Academy, they felt that they were about to complete the mission given to them by the state, and the reality would tell them that it was still early!

"Teacher, in your eyes, what kind of equipment is the top scientific and technological equipment?" This was already the last question, and one student rushed to ask.

"Technology knows no bounds, as you can imagine, just last year, our steel and potassium greatsword ship has proven to the world that our world is a sphere, so we need to build at least a vehicle that can reach any corner of this world in a day to be called perfect, I will call it an airplane. Also last year, we have developed a submersible that can sink low and float again, so can we build a submarine that can sail freely in low water for a long time? I think it should be possible, and even equip the submarine with very powerful offensive weapons, so that it can completely surpass the warships on the surface. If we think about it further, can we build a flying machine that can transcend the gravitational pull of the earth, rush out of this world, go to space, or even grab a handful of dirt on the moon, build a house, and come back. This is technology, it can do anything, but we need to continue to study and discover, and the science we learn is to figure out what kind of help everything in the world can give us in the manufacture of science and technology. ”

Yang Lin's answer brought almost all the students into a dream, at this moment, the seeds of science sprouted and grew wildly in the minds of the students, and they didn't need Yang Lin to inspire them anymore, they just wanted to remember every science taught by Yang Lin.

"Next, our physics first moment begins. In the battle of southern Xinjiang, a soldier who received an order to retreat quickly felt that something was flying next to his head, he grabbed it casually, and found that Jingran was a bow and arrow shot by the enemy, fortunately, the bow and arrow did not hurt him, and even the other soldiers who were shot in the retreat were only slightly injured, because the bow and arrow could not penetrate their leather armor at all, another battle, all the soldiers obeyed the order to move forward, the same arrow, the same distance, the same leather armor, the soldier's comrades suffered heavy losses, the soldier was very strange later, so he came to ask me, I told him, This is the force of inertia. There is a huge difference between the force generated by the collision of driving in the same direction and driving in the opposite direction, so the soldier ran forward when he saw the enemy pulling his bow in the later battle, and ran back a few steps when he saw that the bow and arrow were about to shoot to himself, and suggested that his general commanded the soldiers to run like him, and as a result, the casualties of our soldiers were greatly reduced in the battle, which was a little help to us after capturing the inertial force. So let's do an experiment......"

The students were immersed in the stories and theories told by Yang Lin, and soon after a class passed, they realized that science is not only a profound knowledge, but also a very interesting knowledge, and the physics knowledge learned in this class also made them remember and unforgettable.

After the lecture, Yang Lin went home in a hurry, and his subordinates came to report that someone from Li Tai, the king of Wei, had come to visit the house, which made Yang Lin a little surprised.

"Xiaguan Zhang Jia, see the Heavenly Bestowal Horse."

A middle-aged man in his forties didn't say much after paying homage, took out an envelope from his arms and handed it to Yang Lin.

"This is ......" Yang Lin opened the envelope, and the more he looked at it, the tighter his brows became, and his displeasure suddenly grew.

"Someone, send off."

Yang Lin shouted angrily to the guard at the door, turned around and walked towards the inner hall, the letter in his hand was almost crushed by him.

"Is it finally going to start, the matter of your brothers has something to do with me, just don't mess up the hard-won situation in this country."

Yang Lin was chattering in his heart, but he was stopped by the guards who came suddenly, a person dressed as a eunuch followed him, and hurriedly handed over a letter, Yang Lin opened it and looked at it, and immediately became angry, drank back the two, and said with hatred in his mouth: "And you old pervert, I said why haven't you moved for three years, it turns out that you secretly went to the Western Regions to pick women, now it's okay, your two sons and the rebels in the Western Regions will kill you, see who can save you."
