Mao Zhenguo saw that Senior Brother Sanduo stopped talking and talking, and looked at Su Zhe with a stunned expression, he raised his hand and shook it in front of Senior Brother Sanduo, "Senior Brother Sanduo!" How stupid are you. ”

"You're stupid!" Qian Sanduo reacted.

Su Zhe's new technology can create optical lenses with femtometer precision, and the purity of optical detectors or specific wavelengths of light can be improved by several orders of magnitude.

Thinking of this, he felt that China was about to usher in a big explosion of science and technology.

"Senior Brother Sanduo! What do you think! Your goofy expression. Mao Zhenguo pushed Qian Sanduo and said.

"Who are you talking about?" Qian Sanduo glared at Mao Zhenguo.

"I said I could do it myself! Look at the podium, Professor Changsheng is about to give a lecture. Mao Zhenguo said and looked at the podium.

Qian Sanduo turned his head to look at Su Zhe and asked in a low voice, "For new technologies, what are your chances of success?" ”

"Well...... Ninety percent! Su Zhe thought for a while and said.

"Good! Ninety percent good! Qian Sanduo said excitedly.

"New technology! What new technology? Mao Zhenguo asked curiously.

"Nothing! The lecture began. Qian Sanduo smiled and looked at the podium.

Su Zhe smiled and looked at the podium.

He knows very well that with the advent of femtometer-level optical lenses, the field of human observation will be broadened again, and the field of view will be smaller and farther.

On the podium, Ning Changsheng smiled and said, "Okay! Now let's move on to today's topic, the treatment of tumors by light...... Now in the hospital, the treatment of tumors by light has been used, but those light treatments are too violent, and have great limitations, today I want to talk about the treatment of tumors is different, not only can accurately locate tumor cells in the human body, but also can be accurately removed, of course, there are many problems to be solved...... The treatment of tumors by light is actually ......"

……

In the lecture hall, the voice of Ning Changsheng's explanation clearly reached the ears of everyone, and many of the people who listened carefully to the lecture wrote the key parts in a small book while listening.

Su Zhe listened very carefully, and he had a basic understanding of the treatment of tumors explained by Professor Ning Changsheng Ning.

The core principle of light treatment for tumors is that different cells have different spectra and absorb and release different wavelengths of light.

Based on this principle, the first step is to locate and find the tumor cells in the human body, and then to accurately remove the tumor cells.

This is how the light treatment technology for tumors is realized.

At the beginning, the spectrum of tumor cells is determined, and then the spectrum of tumor cells is compared with the spectrum of other cells in the human body to find out the unique spectral segment of tumor cells.

Then, according to the unique spectral segment of tumor cells, a specific wavelength of light is used to find and locate tumor cells in the human body.

After obtaining information about the location of the tumor cells, two specific wavelengths of light are used to remove the localized tumor cells.

After hearing this, Su Zhe felt a little dreamy.

Different substances have different spectra, which he can accept and prove.

However, it is difficult to locate the location of tumor cells in the human body, and the light used for detection needs to be penetrating and not harmful to the human body.

High-intensity light is definitely not possible, only special wavelength light can be used, which is not easily absorbed by the human body.

Once the location of the tumor cells is known, the next step is targeted removal.

Two specific wavelengths of light are used to shoot at the targeted tumor cells, and two wavelength-specific beams of light are superimposed in the tumor cells, and the superimposed high energy is used to kill the tumor cells.

Here, Professor Ning Changsheng Ning mentioned that three beams of light, or more beams of light, can be used depending on the need.

Su Zhe estimated.

Theoretically, this kind of light treatment of tumor cells is possible.

But in reality, there are too many technical difficulties that need to be broken through.

……

When Ning Changsheng introduced, the formulas, parameters, and calculation process on the big screen were clearly written.

The most exaggerated thing is that Professor Ning Changsheng Ning has made a device that simulates light for tumor treatment, in which the positioning system of tumor cells, the removal system of tumor cells and so on have been made.

After everyone in the lecture hall listened to Ning Changsheng's explanation, nine out of ten people were shocked.

The theory is so complete, and the treatment equipment is simulated, can you not be shocked!

After Ning Changsheng finished explaining, he looked at the shocked crowd in the audience, and said with a smile: "Actually! This technology can be used not only to treat tumors, but also to other diseases, as long as the causative agent is found...... Good! Next is question time, have a question you want to ask? ”

Su Zhegang wanted to raise his hand, but Mao Zhenguo, who was sitting next to him, stood up directly and said excitedly: "Changsheng...... Hello Professor Ning! I am Mao Zhenguo, a student of Professor Huang Weicai Huang, and I am in my second year of graduate school this year, and my research direction is to improve the purity of monochromatic light. I want to study immortality...... I want to realize the technology of light on tumor treatment. ”

Mao Zhenguo's behavior of not playing cards according to the routine directly made the lecture hall lively.

"This little fat man doesn't follow the rules, it's too unusual...... Professor Ning! I study mathematics, can I study with you for a master's degree? ”

"Immortality! I'm going to study immortality! I want to confirm the theoretical conjectures in the paper "The Light of Life", and I want to win the Nobel Prize. ”

"Professor Ning! I just graduated with a Ph.D., and you need an assistant ......"

……

"Everyone, be quiet!" Ning Changsheng saw that everyone was quiet, he looked at Mao Zhenguo and said, "I know you, I have read the paper you wrote, and you have a lot of insights into the research on the improvement of the purity of monochromatic light...... I have no problem with you studying for a PhD with me, but you have to get your teacher to agree...... Don't stand still, sit down! ”

"Professor Ning! Rest assured, my teacher will definitely agree. After Mao Zhenguo finished speaking, he sat down excitedly.

As soon as Mao Zhenguo sat down, everyone raised their hands, and Professor Ning randomly selected one person.

……

After answering a few questions, Professor Ning chose Qian Sanduo.

"Hello Professor Ning! I am Qian Sanduo, a student of Professor Huang Weicai, and the treatment technology of light for tumors is theoretically feasible, but there are many technical difficulties, among which the search, positioning, and removal of tumor cells require extremely pure monochromatic light, I wonder how Professor Ning solves this problem? Qian Sanduo said seriously.

He felt that the treatment technology for tumors alone was the same as the controlled nuclear fusion technology, there were theories and everything, and the engineering was too difficult to implement.

"Not bad! As a student of Professor Huang, he asked directly about the point. Ning Changsheng smiled and said, "To improve the purity of monochromatic light, the most important thing is to improve the accuracy of the optical lens, I have calculated, as long as the processing accuracy of the lens reaches the sub-femtometer level, I can make monochromatic light that meets the requirements, and the optical lens research center of Shangling University has recently made an optical lens at the picometer level!" I believe that in some time, Professor Bao and they will be able to make sub-femtometer-level or even femtometer-level optical lenses. ”

"This ...... Me, well! I understand. When Qian Sanduo sat down, he glanced at Su Zhe who was sitting next to him.

Su Zhe sat there very calmly, looking at him with a smile.

"With femtometer-level lenses, it is possible not only to realize the treatment technology of light on tumors, but also to create a weapon in science fiction movies...... Lightsaber! Ning Changsheng didn't care about the shocked crowd, and explained the relevant principles of the lightsaber, "The realization of the lightsaber requires multiple beams of monochromatic light with very high purity, from ......"

While explaining, Ning Changsheng wrote the formula and the calculation process on the blackboard, writing, stopped, looked at the formula on the blackboard, and then looked at the people in the lecture hall, and asked, "Does anyone know the calculation result of this formula?" ”

In an instant, the lecture hall became quiet, and everyone was staring at each other.

After a long time, the crowd began to whisper.

"I know every word and every letter on the blackboard, but when they are connected, I am dumbfounded."

"What? What's written on the blackboard! My Ph.D. in physics is a fake! ”

"Who would! Professor Changsheng is a big bull, if it weren't for the accident, he would have become an academician long ago...... Lightsaber! Can it be achieved? Is it theoretically possible? ”

……

Su Zhe sat there, looking at the blackboard, his brain quickly calculated the principle of the lightsaber in Professor Ning's mouth, and after a while, his face turned red and fine sweat appeared on his forehead.

Soon, the results of the calculations came in.

The lightsaber in Professor Ning's mouth is really feasible in theory.

He wiped the sweat from his forehead, and his face quickly recovered.

In the whispers of the crowd, he slowly raised his hand.
