Chapter 741

The University of London, or UCL for short, was founded in 1826. It is a world-famous comprehensive research university, ranking among the top ten in the world.

Although he had planned to walk alone, Gu Hengbo followed.

Different from Tsinghua and Peking University in China, the access control of London University is not so strict. After simple registration, they easily entered the world's top university.

Chen Liang took out his mobile phone and didn't know who he was sending a message to.

Gu Hengbo began to take photos again.

Although she has not read too many books, she still yearns for, or even awes, such a top university in the world.

"You know, 34 Nobel Prize winners and 3 fields prize winners were born here."

After a while, Chen Liang put away his cell phone.

Gu Hengbo, who was busy shooting tall camphor trees and beautiful scenery in the school, was surprised at his speech.

"So powerful?"

"This is the top ten universities in the world, don't you think."

With a smile, Chen Liang suddenly stepped forward and asked a passing male student the way in familiar English.

"Let's take you to experience the classroom of the world's top universities."

Holding Gu Hengbo, he wandered around the University of London, then entered a teaching building and quietly entered a ladder classroom.

There were nearly 200 students in the classroom. A beautiful young blonde teacher was giving a lecture. She didn't seem to find two more uninvited guests in her classroom. Maybe she noticed that she didn't care.

In college classes, teachers are generally tolerant as long as they are not too excessive.

Chen Liang and Gu Hengbo found two empty seats in the back row and sat down.

It should be the first time to experience such an experience. Gu Hengbo seemed to skip class when he was a child. He was nervous and his palms were sweating.

This should definitely be a valuable and novel experience for her.

"It's all right. I haven't been found."

Chen Liang winked at her.

Gu Hengbo quickly glanced at the podium, bent over and lowered his voice.

"What are you doing here?"

"Let's see what's the difference between western education and domestic education."

Chen liangruo has nothing to do with it.

But Gu Hengbo obviously won't believe such a statement.

Although puzzled and curious, in order to avoid being noticed, she couldn't continue to ask questions.

The big class with so many people is generally not a serious professional class.

The female teacher on the podium smiled and said, "students, I want to ask you a question. In the court, a criminal will be sentenced to hanging. The judge who is famous for his words and deeds announced that the hanging will be held at 12 noon one of the seven days next week, but you will not know it until you are notified in the morning of the day of execution.

After finishing the above words, the criminal's lawyer immediately smiled and said: the judge can't execute the hanging. Because on the seventh day, that is, the last day, they can't hang you, because if you don't serve the sentence at noon on the sixth day, you know that the hanging will be held on the seventh day, that is to say, you already know the execution time before the morning of the seventh day, which is different from the sentence Never. Therefore, it is impossible to execute on the seventh day. Therefore, the sixth day becomes the last day of possible execution. According to this logic, it is impossible to execute on the sixth day, because if you are not dead on the fifth day, you will know that the execution time is the sixth day, so they can't hang you on the sixth day. Similarly, they can't hang you on the fifth, fourth, third and third days 2、 You were hanged the first day. So you were saved.

The criminal was very happy and thought he was safe, but at noon the next day, the executioner came to him. Of course, it was beyond his expectation. "

The female teacher looked at the audience.

"The judge did not violate his judgment. But the lawyer's logic seems to be no problem. So where is the problem?"

The top students here were all immersed in thinking for a moment.

Listening to Chen Liang's simultaneous translation, Gu Hengbo couldn't help frowning.

Her quick thinking is good, but it's still difficult to figure out such a complex problem for a while.

This seems... To be a paradox?

"This classmate, you answer."

A minute was given to think, and then the female teacher took the initiative to start some people.

The direction she looked at seemed to be coincidental. Unfortunately, it was the position where Chen Liang sat.

obviously.

Just now, they sneaked into the classroom, which seemed unknown. In fact, she caught them.

All the students immediately looked back.

Gu Hengbo didn't know that disaster would come from heaven. His body was subconsciously tense. He looked at Chen Liang nervously and squeezed sweat for him.

In full view of the public, it must be impossible to hide. Chen Liang had no choice but to stand up slowly.

He took a gentle breath.

"This problem is not difficult."

"Tell me what you think."

The female teacher looked at him and said.

"The reason why the lawyer came to the conclusion that he could not kill the criminal on Friday was that he could not inform the criminal to execute the death penalty on Saturday, that is, inference.

The inference on the inference must be established on the basis of the previous inference, and the later ones are the same. That is, if the death penalty is not allowed on Monday, all the previous inferences must be established, and the criminal must live on Saturday and then on Friday

But people can't live from the future to the present. Criminals are doomed to live only from Monday, so the first inference is wrong. The inference behind lawyers is all based on a wrong inference. To sum up, the lawyer's logic is inverted. In other words, he misled criminals, which leads to the illusion that he won't die. If this problem starts from the right When the surface starts to deduce, there is actually no problem. "

Chen Liang took his time. He didn't seem to have the consciousness of being an uninvited guest at all. He talked with a group of top students from London University.

"Of course, we can also understand that this is the kindness of the lawyer. At least before his execution, he eliminated the criminal's fear of death and let the criminal spend the last time of his life without worry."

Voice landing.

The whole staircase classroom is quiet.

Then I don't know who took the lead in clapping. Like waking up from a dream, the classroom soon burst into thunderous applause.

These students did not seem to be aware of Chen Liang's identity as an outsider.

After all, foreigners are precocious, and their growth in high school is not much different from that of domestic college students. Chen Liang, in his twenties, is really more like a student of London University.

The female teacher seemed to be surprised by Chen Liang's intelligence. She looked at him strangely, then smiled and nodded.

"That's a wonderful answer. Please sit down."
