A lot has happened in the past three or four months, and it is not only the changes in Shiping. Baidu search literature network, more good free reading.

Du Ruhui, who was originally going to die in March, has been reinstated and once again contributed to the construction of Datang.

Because of the war with the Eastern Turks, the Central Plains people who were originally captured or raised outside the Saiwai returned to China one after another, and the number reached more than one million

This also brought back a large number of laborers to the "thin" Datang. Of course, first of all, Datang can eat these people.

At the end of last year, a person from Datang who left the country without permission had set off from Chang'an and headed all the way north. This person is a famous monk in later generations, and he was written by a person as Li Er's royal brother Xuanzang

Originally, Ding Yi was going to meet this archmage, but he had to give up because he was entangled in affairs.

On this day, a little fat man danced and waved something similar to a stick in his hand and found Ding Yi

"Ding Yi, hurry, I found something amazing" can be called a little fat man, and the only one who dares to call Ding Yi's name is Li Tai, who is the vice president of the research institute.

Ding Yi glanced at Li Tai impatiently, and was stunned when he saw what he handed over

How to say it

It is a cylinder made of copper, one large and one small, but the two ends are blocked with clear glass.

The work of making a microscope for Sun Simiao is the responsibility of the research institute, but those craftsmen only know how to follow the drawings, but they don't understand it.

In the end, only a lot of lenses were grinded, and the microscope had no clue. The things in it were too precise, and the vision and tools were limited, so they could only die down, and Sun Simiao also gave up observation.

Li Tai, who returned to school after the year, fully demonstrated his responsibilities as the vice president of the research institute. Baidu search literature network, more good free reading.

After making the rotary tiller and other things, their academy physics team, which was linked to the research institute, set their sights on the microscope that the craftsmen had not been able to make.

Young people are always more curious than adults, they are curious about everything, and after knowing the world as a baby, they always think about what the world is like.

Of course, this is due to the influence of their long-term study of physics.

They are not like other teenagers in the Tang Dynasty, they don't care about how to live, they are not disturbed by worldly and complicated things, they are in the academy to explore the fundamentals.

And Li Tai, when everyone had no clue, put two different lenses together before and after.

As he tried to look his eyes from one lens to the other, a bubble hanging from under the nose of a group member suddenly appeared in front of him.

He was startled, the member was a foot or two away from him

Settle your mind and pick up the two lenses again.

Li Tai saw the whole world

The distance from the laboratory to the gate seemed to be unable to stop his gaze, and the blurred figure in the distance was clearly presented in front of him.

Finally relieved, it's not something scary

After many experiments, Li Tai finally made the first meaningful thing in his life, the telescope

After verification, he finally made this first generation in his hand, and it was also the first telescope in Datang, although Ding Yi had a better one in his hand

This discovery made him overjoyed, and he was really overjoyed

After success, he couldn't wait to come to Ding Yi with the finished product

He wanted to show off, which was something that Ding Yi had never said

In the past, he felt that Ding Yi's knowledge was like a vast ocean, and his whimsical ideas were countless. And now, he Li is not convinced that Rentai has also made something that is not available in this world

Showing off was the first thing that came to his mind, but he had chosen the wrong person.

When Ding Yi saw Li Tai's expression, he wanted to take out the eight-fold mirror on the sniper and show it to Li Tai, but when he saw the child's hopeful face, he didn't want to hit him.

"This thing is called a telescope, you can make it yourself, it means that you have the potential to become a physicist, and you must be good at discovering" Ding Yi flickered shamelessly, not making this little fat man proud.

"Telescope"

Li Tai was stunned for a moment, and then reacted: "You know this thing"

As soon as he made it, Ding Yi was able to say its name, and it was so apt that Ding Yi must know this thing, otherwise how to explain it

"Well, I know. It's not me hitting you, your telescope is almost meaningless. There are only two lenses, and they are monocular. The distance is also a little close, and I can only see less than a mile away, and it is not clear" Ding Yi picked up the first-generation telescope and looked out the window.

"Two lens monoculars"

Li Tai confirmed that the person in front of him really knew and used this thing.

"It's hard to see farther than a mile"

"In this way, you go to the academy first, call everyone to the playground, and I'm going to give you a basic physics lesson" A sheep is also a chase, and a group of sheep is also a chase, so it is better to give everyone a physics lesson directly.

Li Tai took his telescope and walked away in frustration, while Ding Yi went to the research institute, found a few concave and convex mirrors and walked to the academy.

This was originally in the physics book, but the physics book that Ding Yi exchanged was not used for printing and teaching, but copied the courses in it, and deleted some courses that needed to use experimental equipment but did not have them. Also avoid the color books as well as some amazing content written and inside.

Now that Li Taidu has made a telescope, Ding Yi also remembered this.

Li Tai still has some status in the academy, and aside from his status as a prince, a single vice president of the research institute and leader of the physics team is enough to make all teachers and students look at him differently.

Except for Yin Zhiming in the school park, no one else knows the identity of Li Tai and others, this is what Ding Yi requested, and this matter is also fully supported by their parents.

I came here to read and learn knowledge, and I didn't let him come to these peasant children to look for it.

Yin Zhiming applauded loudly, Hou Ye doesn't appear in the academy much now, and Hou Ye originally gave them the opportunity to teach once a day, but they also remembered to teach again.

Hou Ye's public lecture is a big event, and it can't be delayed. Yin Zhiming was excited for a while and forgot about the lost Li Tai in front of him, and hurriedly went to call someone.

At this time, the academy was in class, but when the teachers heard that Hou Ye was going to open a class, they immediately stopped the chalk in their hands

That's right, chalk is easy to make, and it was made early on and applied to the academy.

The students were also excited, Hou Ye's open class has not been held for a long time

Calculated carefully, Hou Ye should be regarded as their master

One by one, the students put on the bench and ran to the playground with pencils and notebooks, waiting for Ding Yi's arrival.

At this time, the teachers, like the students, prepared paper and pencil to listen to the class
