The students of Beijing Normal University seem to have become accustomed to such a new atmosphere like a spring breeze. Pen? Interesting? Pavilion wWw. ｂiquge。 infoThis is also the reason why His Majesty the Emperor was the first to establish a normal school in the early days.

Refresh the atmosphere, not the original ones, and only think about how to take the imperial examination.

The class continues.

The students are very serious, and there are not only sixteen or seventeen-year-old teenagers here, but also middle-aged people in their thirties and forties. Together, they all know how rare an opportunity is to be like this.

Cai Taoyuan continued: "A classmate mentioned a very important place, I don't believe it. Although, everyone often says that seeing is believing and hearing is false. But in fact, as long as it is processed to a certain extent, it can also be seen as imaginary. I thought about it for the teacher, and this is not only for the teacher to do it, but also for the students to do it together. As long as you have personally appreciated, experienced, and grasped the true meaning, you can make knowledge engraved in your heart. ”

"Ladies and gentlemen, I announce that we will now form our own associations, with a minimum of five people, and then nominate one person to come up and come to me to collect the experimental materials. Note that the lab material is still to be used in the next lesson. Use with care. Okay, give you a hundred breaths of time, form your own association, and start now. Cai Taoyuan said, and the atmosphere in the classroom exploded all of a sudden.

At this time, several people also walked into the large classroom.

Several administrative staff in uniform pushed carts and trolleys into the classroom, pushing one experimental material after another. The most striking thing is that there is a huge pool in it.

Abe Tadaaki watched all this silently, and couldn't help but recall what he had seen and heard along the way.

The hall of Beijing Normal University has been built very large, and there are hundreds of living places such as teachers' and students' houses, canteens, stadiums, playgrounds, etc., and the number of teaching buildings, laboratory buildings, administrative buildings and various teaching buildings is even more doubled.

Among them, a considerable number are still under construction or renovation. Again, there is a part of it that is empty.

And all this shows the abundant financial resources of Jingshi University.

If it is said that the abundant financial resources of the Jingshi University Hall come from the support of the imperial court. Then, if all this money can really be spent on the students, it is obviously even more powerful.

Right now, watching those executives push carts inside, Abe Tadaaki was thinking about ...... That's a lot of money burning.

But the Ming people had money, and they spent it even more on the tip of the knife.

While Abe Tadaaki was thinking wildly, the students had already completed their own associations and came to the stage to collect the materials.

However, neither Abe Tadaaki nor Chen Jianhong, who came to observe, participated, and they were not official students of the Kyoto University Hall.

Of course, this does not prevent them from watching.

The students were very hands-on, and soon they were making models of sailboats out of wood, inserting a stick into the hull as the mast of the sailboat, fixing a small soft sail to the mast, and adding a small piece of weighed iron as a counterweight at the lower end of the stick that passed through the hull.

In this regard, Chen Weihong was obviously a little incomprehensible: "Aren't you afraid that if you put the iron block, the boat will sink?" ”

"This is the counterweight, so that the model sailboat can float steadily in the water. Chen Zhen, don't forget to add a small rudder later. Cai Taoyuan answered the question casually and continued to walk towards the next group.

Abe Tadaaki also asked a few questions in a row for this reason, and Cai Taoyuan answered them carefully.

If after an hour has passed, when all the sailboat models have been made, Chen Jianhong smiled and applauded to congratulate, and then randomly selected a group of students to take the stage.

It turned out that Cai Taoyuan did not bring his own assembled sailboat model.

In the audience, Abe Tadaaki couldn't help but feel a wave of admiration: "It's really a master of art who is bold." ”

Cai Taoyuan seemed to hear these detailed discussions, but he chuckled lightly, disagreed, and continued to watch the students in the audience bring up their sailboat models: "At the same time, I need two completely neutral classmates. The one, yes, the older one, and the one next to him, come up as a witness. ”

Abe Tadaaki looked at Chen Jianhong in surprise.

Chen Jianhong enjoyed the envious gaze of everyone, and respectfully took the stage with Abe Tadaaki.

On the huge basin of water, the sailboat slowly lowered, ripples, and the whole audience was silent, and no one dared to disturb it.

The experiment began.

"First, set up the air ducts, adjust the sink, and fix the orientation between the two." Cai Taoyuan said, and the sound of note-taking sounded in the audience. In this day and age, information is very poor. The words that ordinary people read in their lifetime may not be as many as the words that an otaku in later generations read in a day.

In such a situation, any bit of useful information needs to be written down. Unlike later generations who forget that they can continue to search for it, there is no search engine in this era, and people who are qualified and prepared would rather believe that a good memory is better than a bad pen.

Thinking like this, Cai Taoyuan began to set the orientation of the air duct and the water tank, and then said: "Pay attention, the water surface should be 15 mm below the edge of the tank. Well, drop the sailboat and the upwind ride is about to begin! ”

The audience waited with bated breath.

On the side, the able-bodied instructor slowly and confidently began to operate the blower. In those days, there was no electricity available, so we had to use human blowers.

But it is such a blower, which is already synonymous with advanced in the eyes of many people.

The wind began to blow, and the ripples on the water surface rippled rapidly. The boat was slowly placed again in a place where the wind was evenly winded on the water surface, saying that it was too late and that was fast, when Cai Taoyuan, who was holding the boat, put down the boat that had adjusted the inclined sail, and sure enough, he saw the boat moving in the direction of the headwind.

It's as if the blower in front of you is not blowing the wind towards the classroom door, but sucking in the teacher.

The uproar kept rang out, and everyone stuck their heads out to look forward like one different goose after another. Voices of amazement, admiration, and doubt sounded almost simultaneously.

"It's really against the wind!"

"Strange, strange!"

"This is amazing!"

"Third brother, your sailboat can sail against the wind, is it an immortal method?"

"What kind of immortal method, I'm just a mortal. It is really a sailboat made according to Mr. Cai's words, and it is ordinary. Unexpectedly...... It's really against the wind! ”

……

"Come, feel the direction of the wind." Cai Taoyuan looked at Abe Tadaaki.

Abe Tadaaki stretched out his hand to the air outlet of the blower and said, "It's really blowing out of the door." ”

"That's true!" Chen Jianhong also followed, he seemed more careful, got off the stage and borrowed a piece of paper from the student on the left in the front row, and then went to the tuyere of the blower.

Abe Tadaaki's eyes widened, and he thought: Did you come to the fairy world?
