I'm a marquis in Datang

"Because it was tilted and never fell to the ground, when the sun was shining on it, it actually pierced the lens, and then ignited the dry grass. This incident shocked people in the University of Science and Technology at the time."

"At that time, we didn't understand what it meant, didn't understand why, and didn't know what the principle was. After tossing for several days, we finally discovered that under the sun, as long as the position is selected properly, the glass can gather light to ignite the dry grass. "

Wang Ping said: "And the thickness of the glass, the degree of unevenness, and the intensity of sunlight all have an impact. In the end, we made such a magnifying glass, which can magnify everything in sight, and can also start a fire."

While talking, Wang Ping took out a magnifying glass from his sleeve.The magnifying glass and the magnifying glass of later generations are not too big

The difference is that the outside is edged with round cork, and there is a short handle to hold it, which is very convenient to use.

The servant took it and handed it to Du Qi.

Du Qi took it over, played with it and said: "Yes, yes, you Wang Ping is indeed a talented person, I didn't misunderstand you. This item is very useful."

Wang Ping was relieved when he heard the words. With Du Qi's affirmation, this research was not in vain.

Du Qidao: "Tell me, what reward do you want?"

Wang Ping shook his head like a rattle, and hurriedly said: "Your Majesty treats us with great kindness, and gives us a very high salary, so that we have no worries about food and clothing. Nowadays, many teachers in the University of Science and Technology have status and are respected. This Since it is His Majesty's kindness, how can we expect rewards. What's more, these researches are our duty and what we should do."

Du Qi said: "The duty is the duty, and the reward is the reward. You have made a magnifying glass, and you should be rewarded."

Wang Ping didn't answer the question, and directly changed the topic: "Your Majesty, the subject and the others made a second item when they carefully played with the magnifying glass and studied it."

Du Qidao: "What item?"

Wang Ping said, "Telescope!"

Du Qi was a little shocked when he heard it. He was really surprised. He looked at Wang Ping and said to himself, Wang Ping, you kid is cheating.

Well, in a short time, another telescope came out.You must know that for Du Qi, the telescope is not widely used for personal purposes.But for the generals in the army, it is necessary.With a telescope, it is extremely beneficial in warfare.

Du Qi suddenly said, "Wang Ping, do you know about microscopes?"

"do not know!"

Wang Ping looked puzzled and said, "Your Majesty, what is a microscope? Is it also made of glass?"

Du Qi was relieved when he heard it.

It seems that this kid Wang Ping belongs to cheating, not through the crowd.

Du Qidao: "Forget it if you don't know, let's talk about the telescope. How did you find it?"

Du Qi was quite curious about these findings.

Wang Ping no longer cared about the microscope, and said with great interest: "Reporting to Your Majesty, the telescope is a thing that can see the distant landscape. Speaking of which, the reason why we can discover it is also due to luck. When we played with the magnifying glass, I also wondered what would happen if the lens was not sunken, but protruding, so I made a glass piece that protrudes outward."

After a pause, Wang Ping said: "In this research team, there is a person named Hu Hanshan, who coincidentally uses two sides to polish

After using the mirror together, I found that I can see things in the distance clearly, so I have this telescope.However, the research process was not very smooth, and it took a long time to get today's telescope. "

Du Qidao: "Submit it."

Wang Ping took out the telescope from his sleeve again, which was a monocular telescope.As Wang Ping held one end of the eyepiece and pulled it, the monocular became longer and he handed it out.

Du Qi took it over and picked up the binoculars, and looked outside the hall.Through the eyepiece, you can clearly see Jingguan in the distance, but there is still a limit to this clarity, after all, the polishing of glass cannot meet the standards of later generations.In fact, the current glass still has a certain gap with the glass of later generations, but it is not bad to be able to reach this point.

After Du Qi looked at it, he put down the telescope in his hand and said, "Wang Ping, how far can your telescope see?"

"Three hundred feet away!"

Wang Ping replied immediately, because he had already measured it with Hu Hanshan and others.Within a distance of three hundred feet, it is relatively clear.Once outside this range, it will be very blurry.

Wang Ping continued: "The distance of this telescope can be further as long as we continue to study and polish it. It's just that this telescope is too small to be of much use."

Du Qi said: "Wang Ping, telescopes are very useful. Research on telescopes will continue."

"Yes!"

Wang Ping answered immediately.

He originally thought it was useless, but Du Qi thought it was useful, and Wang Ping was also happy for Hu Hanshan.

Du Qi said in a deep voice: "Whether it is a magnifying glass or a telescope, we must continue to study. You have contributed a lot to the development of these two items. I will allocate [-] yuan to you, and you and Hu Hanshan will each receive [-] yuan." guan, and the remaining [-] guan will be distributed to the rest of the people involved in the research."

"what!"

Wang Ping exclaimed when he heard it.

Was frightened by Du Qi.

Another hundred thousand!

You know, when the glass was developed, Du Qi gave him a reward.Up to now, Du Qi gave another commendation.Wang Ping, however, was a down-to-earth person, shaking his head and said: "Your Majesty, we don't need so many awards. We have received a salary, and we should do things as we should. Therefore, Your Majesty, we don't need such awards."

Du Qi flicked his sleeves and said: "If it is given to you, you will accept it. This is not only aimed at you alone, but also at other industries. As long as useful items are developed, they will have great uses."

After a pause, Du Qi said: "There are more telescopes here?"

Wang Ping said: "Reporting to Your Majesty, I brought three binoculars with me when I came from Yizhou. However, there are two more binoculars left at the station, and I haven't brought them here for the time being."

Du Qidao: "Send the telescope here, and increase the production and research in this area after returning. Because these telescopes, I will use them in the army."

"Yes!"

Wang Ping responded immediately.

Du Qi wrote another note asking Wang Ping to withdraw money from the internal treasury.Now Du Qi's internal treasury is already extremely rich, and it's not bad to describe it as rich.

After receiving it, Wang Ping thanked him and left.

Chapter 994 Gundam Country

Gundam

Less than half an hour after Wang Ping left, another two telescopes had already been delivered.At this time, Du Qi had already finished handling the government affairs, and Du Qi arranged for someone to notify Shangguanyi.

After Shangguanyi entered, he bowed and said: "Your Majesty notified the minister to come, what's the matter?"

Du Qi took out the telescope and said with a smile, "Come on, take a look at this telescope. It was just researched by people from the University of Science and Technology."

After Shangguanyi picked it up, a strange expression appeared on his face.

He looked dumbfounded.

Because I don't know where to start.

Du Qi reminded: "The telescope is to look at the small end, and the other end is aimed at the place you want to see."
