Mao Zhenguo saw that Senior Brother Sanduo stopped talking and looked at Su Zhe with a dumbfounded expression. He raised his hand and waved it in front of Senior Brother Sanduo, "Senior Brother Sanduo! Why are you so stupid?"
"You're stupid!" Qian Sanduo reacted.
Su Zhe's new technology can create optical lenses with femtometer precision, which can improve the purity of optical detectors and light of specific wavelengths by several orders of magnitude.
Thinking of this, he felt that the country was about to usher in an explosion of science and technology.
"Brother Sanduo! What are you thinking about? You have such a silly expression." Mao Zhenguo pushed Qian Sanduo and said.
"Who are you talking about?" Qian Sanduo glared at Mao Zhenguo.
"I said I can do it on my own! Look at the podium, Professor Changsheng is about to give a lecture." Mao Zhenguo said and looked at the podium.
Qian Sanduo turned to look at Su Zhe and asked in a low voice: "With new technologies, what are your chances of success?"
"Well...90%!" Su Zhe thought for a while and said.
"Okay! Ninety percent good!" Qian Sanduo said excitedly.
"New technology! What new technology?" Mao Zhenguo asked curiously.
"Nothing! The lecture has begun." Qian Sanduo smiled and looked at the podium.
Su Zhe smiled and looked at the podium.
He knew very well that with the emergence of femtometer-level optical lenses, the field of view of human observation will be broadened again, and we can see smaller and farther.
On the podium, Ning Changsheng smiled and said: "Okay! Now let's talk about today's topic, the treatment of tumors with light... Nowadays, light treatments for tumors are already being used in hospitals, but those light treatments are too violent and It has great limitations. The treatment of tumors by light that I am going to talk about today is different. It can not only accurately locate tumor cells in the human body, but also accurately remove them. Of course, there are many problems that need to be solved... The treatment of tumors by light Treatment, actually..."
…
In the lecture hall, Ning Changsheng's explanation voice reached everyone's ears clearly. Many of the people who listened carefully to the lecture wrote down the key parts in small notebooks while listening.
Su Zhe listened very carefully, and he had a basic understanding of the light treatment of tumors explained by Professor Ning Changshengning.
The core principle of light therapy for tumors is that different cells have different spectra and absorb and release light of different wavelengths.
Based on this principle, the first step is to locate the tumor cells in the human body, and then the next step is to accurately remove the tumor cells.
This is how light treatment technology for tumors is realized.
First, 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 the unique spectral segment of tumor cells.
Then, based on the unique spectral segment of tumor cells, light of specific wavelengths is used to find and locate tumor cells in the human body.
After obtaining the location information of the tumor cells, two beams of light with specific wavelengths are used to remove the located tumor cells.
After hearing this, Su Zhe felt a little dreamy.
Different substances have different spectra. He can accept this and it has been confirmed.
However, it is difficult to locate tumor cells in the human body. The light used for detection requires a certain degree of penetration and cannot cause harm to the human body.
High-intensity light is definitely not possible. Only light with special wavelengths can be used, which is not easily absorbed by the human body.
After knowing the location information of tumor cells, the next step is targeted removal.
Two beams of light with specific wavelengths are used to shoot at the located tumor cells. The two beams of light with specific wavelengths are superimposed in the tumor cells, and the superimposed high energy is used to kill the tumor cells.
Here, Professor Ning Changshengning mentioned that three beams of light, or more beams of light, can be used as needed.
Su Zhe made an estimate.
In theory, this light treatment technology for tumor cells is possible.
But in reality, there are too many technical difficulties that need to be overcome.
…
When Ning Changsheng introduced it, the formulas, parameters, and calculation process were clearly written on the big screen.
The most exaggerated thing is that Professor Ning Changshengning has made a device that simulates light treatment of tumors, including a tumor cell positioning system, a tumor cell removal system, etc.
After everyone in the lecture hall listened to Ning Changsheng's explanation, nine out of ten people were shocked.
The theory is so complete that it even simulates treatment equipment. Can you not be shocked?
After Ning Changsheng finished explaining, he looked at the shocked people in the audience and said with a smile: "Actually! This technology can not only treat tumors. It can also be used for other diseases as long as the causative agent is found... Good! Next is question time, do you have any questions?"
Just as Su Zhe was about to raise his hand, Mao Zhenguo, who was sitting next to him, stood up and said excitedly: "Changsheng... Hello, Professor Ning! I am Mao Zhenguo, a student of Professor Huang Weicai. I am in my second year of graduate school this year, and my research direction is to improve monochromatic light." I want to ask if I can study for a Ph.D. with you after I graduate from my master’s degree? I want to study immortality... I want to realize the technology of light therapy for tumors.”
Mao Zhenguo's behavior of not following the routine directly made the lecture hall lively.
"This little fat guy doesn't follow the rules, it's so outrageous... Professor Ning! I major in mathematics, can I study for a master's degree with you?"
"Immortality! I want to study immortality! I want to confirm the theoretical conjecture in the paper "Light of Life", and I want to win the Nobel Prize."
"Professor Ning! I just graduated with a Ph.D., and you want an assistant..."
…
"Everyone, be quiet!" Ning Changsheng saw that everyone had quieted down. He looked at Mao Zhenguo and said, "I know you. I have read the paper you wrote. You have great insights into the research on improving the purity of monochromatic light... What are you talking about? I have no objection to my PhD, but you have to ask your teacher to agree... Stop standing, sit down!"
"Professor Ning! Don't worry, 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 someone.
…
After answering a few questions, Professor Ning chose Qian Sanduo.
"Hello, Professor Ning! I am Qian Sanduo, a student of Professor Huang Weicai. The light treatment technology for tumors is theoretically feasible, but there are many technical difficulties. Among them, the search, location, and removal of tumor cells all require purity. Extremely high monochromatic light, I wonder how Professor Ning can solve this problem?" Qian Sanduo said seriously.
It gave him the feeling that this light treatment technology for tumors is the same as controllable nuclear fusion technology. It has theories and everything, but it is too difficult to implement the project.
"Not bad! As expected of Professor Huang's student, he directly asked for the idea." Ning Changsheng said with a smile, "To improve the purity of monochromatic light, the most important thing is to improve the accuracy of the optical lens. I have calculated that as long as the processing of the lens With an accuracy reaching sub-femtometer level, I can produce monochromatic light that meets the requirements. Didn’t the Optical Lens Research Center of Shangling University recently develop an optical lens with picometer level? I believe that in some time, Professor Bao and others will We can create sub-femtometer or even femtometer-level optical lenses.”
"This...I, okay! I understand." When Qian Sanduo sat down, he glanced at Su Zhe, who was sitting next to him.
Su Zhe sat there calmly and looked at him with a smile.
"With femtometer-level lenses, not only can we realize light treatment technology for tumors, but we can also create a weapon in science fiction movies... a lightsaber!" Ning Changsheng ignored the shocked people and explained the function of the lightsaber. Related principles, "The realization of a lightsaber requires multiple beams of very high-purity monochromatic light, starting from..."
As Ning Changsheng explained, he wrote formulas and calculation processes on the blackboard. After writing, he stopped, looked at the formulas on the blackboard, then looked at everyone in the lecture hall, and asked: "Is there anyone?" Do you know the calculation result of this formula?"
For a moment, the lecture hall became quiet, and everyone stared.
After a long time, everyone began to whisper.
"I knew every word and every letter on the blackboard, but when I put them together, I was dumbfounded."
"What? What's written on the blackboard! Is my doctorate in physics fake?"
"Who would do this! Professor Changsheng is a great person. If not for something unexpected, he would have become an academician long ago... Light saber! Can it be realized? Is it theoretically possible?"
…
Su Zhe sat there, looking at the blackboard, and quickly calculating the principles of the lightsaber mentioned by Professor Ning in his mind. After a while, his face turned red and sweat appeared on his forehead.
Soon, the calculation results came out.
The lightsaber mentioned by Professor Ning is indeed feasible in theory.
He wiped the sweat from his forehead and his expression quickly recovered.
Amidst the whispers of everyone, he slowly raised his hand.
