Li Zhen went to look at that paper carefully, and the more he looked at it, the more frightened he became.

"I stumbled upon a phenomenon 10 years ago where a convex lens is exposed to a high level of exposure, and there are traces left behind the convex lens. It was an accidental discovery, but a few years ago, I wondered if there could be a way to keep the scene or the characters. Something rubbed on paper on the spot. ”

"Originally, I thought it would be impossible to do this, because it was simply impossible. But I suddenly remembered the phenomenon of convex lenses, which I discovered a few years ago, and I started to work on it......"

"After three years, I finally discovered such a phenomenon."

"A convex lens is able to concentrate light, and the point at which the light converges, I call it a focal point. After the convex lens, prepare a darkroom without any light. Place a card in the darkroom with an oiled photosensitive substance. Under the bright light, the 'door' of the darkroom is instantly opened and closed. At this point, what the convex lens sees is upside down and shrinks on the card in the darkroom......"

"I call this principle the 'photographic principle'......"

Li Zhen looked at this paper and only felt full of wonder.

Others came to circulate it one after another, and after reading it, they only felt shocked:

"This ...... Really? ”

"Just light, to be able to leave a reflection on a card?"

"It's really amazing. A moment exposed with a convex lens to leave a scene on the card? ”

"If this principle is confirmed, wouldn't it be possible to record landscapes and people without the need for a painter?"

"I can't believe it."

"Tsk...... Exposure, focus, light screen. Are these the technical terms he came up with? ”

"That's hard to judge. The Department of Physics of the Kyushu Academy of Sciences does not have a department that studies optics. ”

“……”

Li Zhen is also a little blind, how to judge this?

I don't know optics myself.

The Kyushu Academy of Sciences is almost blank for optics, and there are very few people who are interested in optics.

But Li Zhen has to say that there are really talents everywhere. The new Kyushu is really good for its vast land and resources, and talents in various fields are emerging in an endless stream.

No, now there is a figure who has completely shaken the blank project of the Kyushu Academy of Sciences.

Li Zhen said: "The paper says that he has already made the finished product? It's called Jia Fan. Go, invite Mr. Jia here, and we'll verify it on the spot. ”

“……”

Laoshan County.

An old man was lying tossing and turning in the inn, holding a large box in his arms, his face full of worry.

"I don't explain optics well enough. The Kyushu Academy of Sciences is the most important theory. This time, I won't even have a nomination award, will I? ”

"Alas, give me another year. I'm sure I can explain everything in detail. But time doesn't wait for me, my body may be burping that day, can I still see that day? ”

"In New Kyushu now, there is almost no space for optics. No one has done anything to study this seemingly simple light. This photographic technique is another wonderful phenomenon that I stumbled upon, and I don't know ...... this time."

As he was tossing and turning, there was a knock on the door.

Jia Fan hid his suitcase under the bed and walked out to open the door. As soon as the door opened, I saw only four or five guards standing in the doorway.

'Who are you?' ’

"Hello, is this Mr. Jia Fan who signed up for the physics prize?"

"Yes, I am. Who are you? ”

"We are people from the Kyushu Academy of Sciences."

"Oh, I'm glad I'll be happy, come in and sit."

"No need. Mr. Jia, Mr. Li invites you to enter the Kyushu Academy of Sciences and show the photographic technique with real objects. Are you available right now? ”

Jia Fanxi raised his eyebrows: "If you are free, you wait, I will take my things and go now." Wait. ”

A moment later, Jia Fan picked up a big box and ran out in a hurry.

The guard smiled: "Mr. Jia, let's help you get it." ”

"No, no, no. I'll just hold this thing myself. ”

"Please..."

Jia Fen trembled and boarded the luxurious steam car, the whole person was like sitting on pins and needles, he had not touched this luxurious steam car up close.

After a while, I came to the Kyushu Academy of Sciences.

Seeing the place that fascinated intellectuals all over the world, Jia Fan swallowed his saliva nervously, hugged his box tightly, and was so nervous that his muscles rose.

He didn't expect that he would have this kind of treatment and be invited to the Kyushu Academy of Sciences in advance. The whole person was excited and nervous.

Turning around, he entered the sacred hall in his heart, the physics department building.

Led by the invitation of etiquette, Jia Fan dragged the big box into the auditorium.

As soon as he entered the auditorium, what appeared in Jia Fan's eyes was an extremely shocking scene.

Those who have only heard the names of the physics giants gathered at this time.

In this brightly lit auditorium, everyone carefully checked the copywriting in their hands, either frowning and pondering, or closing their eyes to recuperate.

Jia Fan couldn't recognize who was who, but when he saw the name tags on each table, he couldn't help but be shocked.

Li Zhen, Fang Hanxian, Liu Jinghong, Ma Jianbin, and more than a dozen physics leaders from the Kyushu Academy of Sciences.

There are also many scholars who were famous all over the world in the early years.

Xu Qingxi, a physics professor at Imperial College.

Physics professors at Imperial College who retired a few years ago, Zhang Zihao and Qin Jianchang......

There are also many who are Jia Fan's predecessors. He is a professor of physics at Fuxing University, who has been retired.

Seeing so many people, they were all reviewing papers under the leadership of Li Zhen, the youngest and thinnest. Jia Fan didn't feel that there was anything wrong with this at all.

Over the years, Li Zhen has already proved to the world that there are miracles in this world with practical actions and strong knowledge. No one will think that Li Zhen is young, because this young man is rich and rich, and he is a genius in every field. Every thought can be many years ahead of the world.

Li Zhen raised his eyes and said with a smile: "Teacher Jia is here?" Have a seat. ”

Jia Fan hurriedly waved his hand: "No need, no need." Thank you. ”

Li Zhen said casually: "We have all seen your photographic theory, but with all due respect, the Kyushu Academy of Sciences does not have a rich knowledge of optics for the time being. So I can't criticize your theoretical papers. This is the only way to do this, and I hope you can verify it yourself. What we hope is that your research is not only theoretical, but also actually able to show the phenomenon you are talking about. What do you think? ”

When Jia Fan heard this, he kept patting his big box excitedly: "I took it." I took it. This is my phonograph. I've already made it. It's better to choose a day than to hit the sun, now is the world's physics community leaders gathered together, or take advantage of the present, I will help you leave a picture of your predecessors. ”

Li Zhen and the others found it interesting and said with a smile: "Okay." ”

"That's a good feeling."

"Hahaha, interesting."

“……”

Jia Fan said, "Master Li, please sit on the chair in the middle. That, Dean Liu, sit next to Master Li. ”

Under Jia Fan's arrangement, there were about 30 people in the auditorium, either sitting or standing. They all looked at Jia Fan fiddling with the equipment with a curious and puzzled look.

But it was strange to see that he had set up a wooden box and then put a piece of cloth on his head.

I saw Jia Fan holding a lamp in one hand and a button connected to a wire in the other.

But I heard Jia Fan shouting behind the box: "Master Li, you look at my side." ”

Li Zhen, who was sitting in the middle of the first row, looked over suspiciously, and heard Jia Fan shout again: "Don't be afraid, there will be a flash later." ”

When everyone heard this, they couldn't help but smile at the corners of their mouths.

This is the time!

Jia Fan suddenly pressed the button in his hand.

There was a bang.

The entire auditorium suddenly flashed with an extremely strong light.

"Ahh

Everyone was startled and stepped back in surprise. Rao is Li Zhen, all of them were frightened by this sudden suddenness.

Just when everyone was in shock, Jia Fan laughed and came out of the brie, waving a card in his hand: "Hahaha, it was successful." Master Li, this is a group photo of you. ”

Everyone looked. I saw a black and white picture on the card. It's not clear, but you can really see the faces and expressions of the characters.

In the photo, it is the people sitting there just now.

Li Zhen excitedly pointed to himself in the center of the photo, in the first row: "I, really left me here." ”

Liu Jinghong also stretched out his hand excitedly and pointed: "This is me." Hahaha, it's amazing. ”

Everyone also hurriedly rushed forward, looking for their figure on the card with great interest. Exhilaration.

The first photo of Li Zhen, here, was left on this card by the flashing light at this time......

And this photograph of the world's top physicists is also the world's first official, successful photo. will become a classic timeless. Everyone in this photo has also been truly left in history for the first time and passed down for centuries!
