Lecture Hall No. 3 on the 5th floor of the HKUST West District Library.

The lecture hall, which has only 280 seats, is rigidly packed with more than 500 people.

Among these people, there are undergraduates, masters, and doctors, and many people still come here.

These people chatted excitedly.

"It's the first time I've come to listen to Professor Changsheng's lecture, is Professor Changsheng really as divine as you preached?"

"Of course, let's not talk about it, Professor Changsheng's recent paper "Light of Life" published in "Cell" has not seen that the epidermal cells of monkeys that are about to die have regained their ...... under the irradiation of a specific wavelength of light."

"Is this true? This is a big discovery! If you figure out the mechanism, the Nobel Prize will be stable, and the immortal professor is a cow! It's dark on the road of studying immortality. ”

……

While everyone in the lecture hall was chatting happily, a handsome man walked into the lecture hall with a laptop.

For a moment, the noisy lecture hall fell silent.

"Su Zhe, this is Professor Ning Changsheng Ning!" Qian Sanduo reminded Su Zhe very quietly.

"This ...... That's not right! Professor Ning should be in his early forties, but this is too young. Su Zhe looked surprised.

Standing on the podium, Professor Ning looked like a middle-aged man in his early forties, and from the outside, he was completely a young man in his twenties.

"Su Zhe! Think about Professor Changsheng's research direction, immortality! Mao Zhenguo lowered his voice very low, "Some people say that Professor Changsheng's self-generated genes are very special, and some people say that Professor Changsheng has changed his genes, and there are ......."

"Don't talk nonsense!" Qian Sanduo pushed Mao Zhenguo.

On the podium, Ning Changsheng put down the laptop in his hand, looked at the people in the lecture hall, and said with a smile: "There are still ten minutes before the lecture, everyone continue to chat, don't worry about me." ”

With that, he began to prepare for the lecture.

The people in the lecture hall were stunned for a moment, and then began to whisper.

"Professor Changsheng is so young, this one looks like he's in his forties."

"This ...... Professor Changsheng won't shine the light of life on himself...... A girl's favorite! ”

"It's incredible...... I don't know if the threshold for studying for a PhD with Professor Changsheng is high, but I want to study immortality. ”

……

"Senior Brother Sanduo! I'm not talking nonsense, or you can explain to me why Professor Changsheng is so young. Mao Zhenguo saw that everyone began to whisper, and he immediately retorted.

"Aging is different for everyone, and some people ...... Some cases are inexplicable. Qian Sanduo wanted to explain, but he didn't think it was necessary.

"Yes! You can't tell. Mao Zhenguo was a little proud, "Senior brother! How about I do a PhD with Professor Changsheng? Will the teacher beat me to death? ”

"I guess it will, you must know that the teacher values you very much, besides, Professor Changsheng has cheated the teacher." Qian Sanduo smiled and nodded.

"The teacher is also good enough, isn't it just a million electricity bills!" Mao Zhenguo said and looked at Su Zhe, "Huh! Su Zhe, you are from Hanxi Province...... How did you get here? It's still with Senior Brother Sanduo! ”

"Little hair! You've got a lot of care. Qian Sanduo smiled and said, "Su Zhe studied with Professor Bao Zhengyi Bao at Shangling University during the summer vacation, and this time he followed Fan Xiaoming to the University of Science and Technology. ”

Su Zhe smiled and nodded.

"Not bad! Not bad! Professor Bao and Fan Xiaoming are both geniuses. Mao Zhenguo looked like a big brother, "You studied physics, they too, and they are all from Lingzhou Institute of Technology, your relationship with them will be of great help to your future development, I will tell you ......"

"Mao Zhenguo! Say what! Qian Sanduo smiled awkwardly at Su Zhe.

"I said this for Su Zhe's good, and I won't say it for ordinary people." Mao Zhenguo looked like he didn't care.

"You...... Too lazy to talk about you. Qian Sanduo looked at the time, "It's time for the lecture, listen to the lecture carefully." ”

On the large screen on the side of the podium, a few big words were displayed: Light for the treatment of tumors.

Everyone looked at this, and there was no longer a discussion, and the lecture hall fell silent.

Ning Changsheng raised his head, looked at the people in the audience, smiled and said: "Thank you for taking the time to attend my lecture, today's topic is the treatment of tumors by light, before talking about today's topic, I will talk about some others, the first thing to talk about is the learning of scientific knowledge......"

Su Zhe listened for a while, and understood what Professor Ning Changsheng Ning wanted to express.

Don't care about the so-called division of disciplines, and don't limit the boundaries of learning knowledge because of disciplines.

"Physics, chemistry, and biology are separated in textbooks, but in reality they are not, and there is no clear boundary between the three." Ning Changsheng said seriously, "Just like my paper "The Light of Life" published in "Cell" not long ago, the core of the paper is that the epidermal cells of monkeys are reborn under the irradiation of a specific wavelength of light, and this paper involves physics, chemistry, biology, and of course, mathematics must be indispensable. ”

There was applause from the audience.

After Ning Changsheng and the applause passed, he continued: "In my opinion, you must learn biology, chemistry and physics; To study chemistry, you must study physics...... Of course, what I'm talking about is to engage in basic research, if it's just at the application level, just learn the relevant professional knowledge, after all, you don't need to delve into the mechanism behind the phenomenon. ”

There was applause again in the lecture hall.

Su Zhe agrees with Professor Ning Changsheng Ning's point of view, in his opinion, biology is the most complex, then chemistry, and finally physics.

It's very, very difficult to learn chemistry and biology well.

"Take the paper "The Light of Life" as an example, we did ten groups of experiments, nine groups of experiments, the epidermal cells of the monkey were reborn, after the analysis of the data and speculation, the epidermal cells of the monkey were irradiated with a specific wavelength of light, the nucleus in the cell was activated, to be precise, the chromosomes in the nucleus were activated...... Unfortunately, many of these are conjectures and have not been experimentally confirmed. Ning Changsheng said with a smile, "When we analyze, we involve not only biology, but also chemistry and physics...... By the way, if the one sitting in the room had experimentally confirmed the theoretical conjectures in the paper, then we would have stood on the Nobel Prize podium together. ”

As soon as Ning Changsheng's words fell, the audience instantly became lively.

"Isn't it! To win the Nobel Prize, so good! ”

"Big brother! Immortal! Do you think you can win the Nobel Prize? ”

"I'm going to study this paper well, and if I confirm it, then ......"

……

"Senior Brother Sanduo! I'm going to do a Ph.D. with Professor Changsheng, the Nobel Prize! Mao Zhenguo said with some excitement.

"Little hair! You think too much, at your current level, it's too bad, I have read the paper carefully, and I want to confirm it, the first thing to improve is the detection accuracy of the optical detection instrument, and then the purity of a specific light, to achieve these, you need an optical lens with higher precision, which ......" Qian Sanduo began to look disgusted, and as he spoke, he looked at Su Zhe in surprise.

Optical lenses with higher precision, Su Zhe and they are doing this now.

If Su Zhe's new technology succeeds, then ......
