my scientific age

Chapter 53 Rename
Yu Hua is looking forward to the school's attitude towards portable lighting sources.

If you support it, you can barely maintain the current situation, but if you oppose it...

Yu Hua could only reluctantly give up.

After all, although the portable lighting source is just a necessity for students, in fact, it violates the school's dormitory management regulations. The school has turned a blind eye to the students reading books with kerosene lamps.

Attitudes from the school side are crucial.

From a personal point of view, Yu Hua hopes that the school can support, or at least not oppose, although life is not just for the moment.

But what Yu Hua wants now is humility.

That's hundreds of oceans, and it's tens of thousands of yuan converted into later generations.

Fang Yu, who was directly abandoned, bit her lip: "..."

He could only watch Yu Hua go out under the call of Mr. Ren.

Helpless, yet irritable, the whole person was in a bad mood all of a sudden. Yesterday, the huge news of the boys' dormitory had spread all over the school. After a night of fermentation, everyone was very curious about Yu Hua's portable lighting source.

Especially girls!
Due to the difference between men and women, girls can't go to the boys' dormitory to watch it up close, let alone experience the taste of independent electric lights.

After the morning exercise today, Fang Yu, who was usually quiet and low-key, couldn't hold back his curiosity after all.

Don't know when he will come back.

Sitting in his seat, Fang Yu was eager to see Yu Hua outside the window.

When he came to the corridor, Mr. Luo Wenguang had a natural demeanor and could not see any emotions. Yu Hua showed an ignorant and simple look, and greeted respectfully, "Hello, sir."

"Yu Sheng, I heard that you made an independent light bulb?" Luo Wenguang smiled at the young and somewhat innocent Yu Hua.

"Mr. Hui, in the student's dormitory, students light kerosene lamps every day to read and study. The dim light of the kerosene lamp leads to weakened eyesight. The students remembered the knowledge they had learned before in physics, and after studying it for a while, they used the equipment on the market to make a A set of portable lighting sources, that is, stand-alone electric lights, allows students in the dormitory to read books under the light of the electric lights, so as to reduce the damage to the eyes." Yu Hua heard Luo Wenguang's question, and immediately said something that he had already made up in his heart.

Focus on describing the disadvantages of kerosene lamps, emphasizing that dim light will lead to weakened eyesight, and the purpose of making this set of independent lamps is for dormitory students, not for making money.

Not a word about making money off portable lighting sources.

Hearing that, Luo Wenguang immediately became interested: "Oh? Will dim light also lead to weakened vision?"

It was the first time he had heard of this theory.

"Yes, for example, when you are reading a book in a dark environment, your eyes will become swollen and swollen after a while, which will lead to weakened vision over time." Yu Hua briefly explained, popularizing common sense that is well known to the world.

The common sense that most people in later generations knew was extremely novel in the period of the Republic of China when knowledge was scarce.

For example, dim light leads to weakened eyesight. Many teachers, teachers and students have experienced it, but they have not summarized it into theoretical knowledge at the written level.

"I didn't expect kerosene lamps to have such disadvantages, so you must read in a bright environment when reading?" After listening to the concise and straightforward description, Luo Wenguang recalled that when he was reading, it was exactly as Yu Hua described. , sighed.

Yu Hua nodded: "Yes, but too high brightness is not good. Too high brightness will reflect light, which will also cause vision loss."

"Not bad."

Luo Wenguang looked at Yu Hua, nodded and praised: "This point of view is very good, and it can be promoted to the whole school. Yu Sheng, what is the effect of this set of independent lights you made, and how long can it keep lighting stable?"

"Using 100-watt incandescent lamps, one bedroom is bright and bright, the brightness is just right, and the impact on vision is small. It can be stably illuminated for about 3 hours, and a set of equipment can be used for at least three years." Give the relevant performance parameters.

Luo Wenguang nodded again and again and continued to ask, "What about the cost?"

"Charging the battery once a day costs about 1 cent." Yu Hua replied.

"One dime a day, 3 hours a day, is much more efficient than school lights, with a lifespan of up to three years. No wonder so many students went crazy last night."

When Luo Wenguang got the data, he immediately figured out the monthly cost of the portable lighting source in his mind, and praised: "The independent lights you made are very good."

"Uh...Sir, you don't criticize the students?" Yu Hua asked cautiously after hearing Luo Wenguang's praise.

"criticize?"

Luo Wenguang was a little puzzled: "Sir, why should I criticize you?"

"This set of equipment made by the students violates the dormitory's rule of turning off the lights at 10:30 and going to sleep. There was such a big commotion last night, I thought you would criticize me." Yu Hua said in a low voice.

"Which one of you really obeyed the rule of turning off the lights at 10:30? In the middle of the night, the kerosene lamps in the male and female dormitories are all lit, and the school will not blame you for this." Luo Wenguang laughed and shook his head, looking at the cautious Yu Hua, Said.

The 10:30 rule to turn off the lights and go to bed?

Ask yourself, have you followed it?

Since the establishment of Peking No. [-] Middle School, this rule has been in name only, and no students have followed it.

After finishing their evening self-study, every No. [-] middle school student would either go to the library or go back to the dormitory to continue to study carefully, and would not go to bed until twelve o'clock.

"..."

Yu Hua heard this and didn't know what to say.

"Sir, what about the stand-alone light bulb? Many students want to buy one." Taking a deep breath, Yu Hua asked the most crucial question.

Luo Wenguang waved his hand and didn't care: "They want to buy, you can buy it, what's the matter."

"Okay..." Yu Hua's mouth twitched slightly when he got Luo Wenguang's answer, and he thought about it for so long last night, and it was always unfounded.

The school's attitude seems to be irrelevant.

Yes, don't care at all.

Peking No. [-] Middle School, a good Buddhist.

"Since you can invent this kind of independent light bulb for your classmates in the dormitory, why would your husband criticize you? I hope you can become an inventor like Edison in the future. Okay, let's go in and get ready for class." Luo Wenguang showed a gentle smile and encouraged After a while, he motioned Yu Hua to go in and prepare for class.

Yu Hua nodded and was about to go back to the classroom when he suddenly thought of something that had not been done yet. Taking advantage of Luo Wenguang's presence, he said directly, "By the way, sir, the student has an unkind request. The student wants to change his name."

Renamed.

This is something I had planned before, and I have been so busy since the start of school that I almost forgot about it.

During the period of the Republic of China, it was a very common thing to change the name. The name change of the literati was even called Fengya. Most of the celebrities in the literary world changed their names. For example, they changed their name to Dana Lu Xun, whose original name was Zhou Zhangshou. meaning.

Wen Yiduo's original name was Wen Jiahua, which was later changed to Wen Yiduo. Xu Beihong, a master of traditional Chinese painting, was originally named Xu Shoukang, geologist Li Siguang was originally named Li Zhongkui, and Mao Dun, a household name in later generations, was originally named Shen Dehong.

A name change is not uncommon in this day and age.

However, as a student of No. [-] Middle School, Yu Hua, who wants to change his name, must go through the school's way. Otherwise, unilateral name change will lead to many misunderstandings.

Luo Wenguang raised his eyebrows when he heard the words, looked at Yu Hua who looked respectful, and asked, "What name are you going to change?"

"The birch character, remove the wooden character next to it, and take my Chinese character as the name." Yu Hua said the new name truthfully.

Luo Wenguang thought it over carefully and commented: "Yu Hua, this name is not bad. It's atmospheric and correct. Are you sure you want to change the name?"

"Sure." Yu Hua nodded.

"Okay, you go in first, and come to my office during the lunch break. It's still more troublesome to change the name after the principal's signature." Luo Wenguang nodded and warned.

Yu Hua hurriedly responded, without delay, bid farewell to Luo Wenguang, turned around and entered the classroom, returned to his seat and sat down under the eager and curious eyes of all the classmates.

"Yu Hua, what did Mr. Jiren say to you?" When Yu Hua sat down, Zhou Yuan leaned over and asked.

Yu Hua shook his head: "I just asked about the basic situation of the portable lighting source. It's nothing. It's about to go to class. Let's talk later."

When the words fell, I bowed my head and sorted out the Chinese books, and got ready for class.

At this moment, Yu Hua suddenly felt that there was someone at the table, and when he looked up, it was Fang Yu.

"Student Yu Hua, can you talk about portables..." Fang Yu stood in front of the table, pursed his lips, and said softly.

"Boom!" Before Fang Yu could finish speaking, a low and distant bell sounded from outside the classroom.

Class begins.

PS: Sorry, there are too many things at home in the past two days, I will add more tomorrow.
