Dafang's every question will make the students present react, and this time is no exception, everyone, including the man with glasses, looked at Zhang Nian, and Dafang also looked at Zhang Nian.

Under the gaze of everyone, Zhang Nian slowly got up and said to Dafang: "Professor, I think I know which one it is." I'm sure all of you remember that picture, that incongruous picture, but because the difference in the picture is so subtle, let's ignore it, until just now I was inspired by your thinking methods and habits, and I found this picture in my memory, and then combined this scene with the housekeeper's behavior, I should be sure. ”

"It's a picture of differentiation and classification." After Zhang Nian finished speaking, he waited for a generous response with his eyes.

Dafang motioned for Zhang Nian to sit down, looked at the audience and said, "Now, let's play back this paragraph, about the picture of differentiation and classification." ”

The movie screen then lights up, and there is a scene that has already been played, a scene from the third act, and the location is the small shop that keeps throwing garbage outside.

"Pap" "Papa" "Papa"

The sound of throwing garbage continues to sound from the picture, as the garbage gradually piles up, there is always a cleaning robot, appearing from the other side, its head is semicircular, and there are two big round eyes on it, but it looks wooden and unfocused, the chest of the cylindrical body, embedded with a small electronic display screen, the front of the two manipulators have three fingers, which is easy to grab, and it also has feet composed of various wheels and tracks, along a fixed route, slowly come, and begin to clean up the pile of garbage.

The rigidity of the rigid robot is once again reflected in the picture, it only cleans up the pile in front of it, and ignores all the garbage that is still being thrown out during the cleaning process, and even the ones that fall in front of it on the head, and will only be removed together until the next time.

"I'm sure you've seen it." Dafang said to everyone.

Wang Chen shook his head very decisively, he said that he didn't see anything, and besides, what is so beautiful about sweeping the garbage, it is not more interesting than the picture of the big black gnawing on fritters.

There are not a few people who agree with Wang Chen's opinion, but there are also many people who can see it, because there is indeed a hidden contradiction hidden in it.

Dafang looked at the doubtful part of the people and said: "The key point is how to distinguish whether the garbage should be swept now or saved for the next time." ”

Wang Chen was unexpectedly the first to react, and he said loudly: "Oh! I know, just like when I was at home my mom insisted on me to wash the dishes, I always felt that washing dishes and washing clothes was enough to wash once a week, Bobo must be as lazy as I was, I think, only people who are used to thinking are lazy, so you brought him back, because he is the smartest one. ”

"Hahaha" everyone laughed.

Wang Chen's cheerful self-deprecation slightly led to a somewhat stagnant atmosphere.

With a big smile, he stopped the noise in the hall and said: "In fact, from an objective point of view, laziness is not a bad habit, if you need to protect yourself at any time in the environment, as much as possible to retain physical strength, it is likely to be directly related to whether you can survive in the next moment of the unknown, the so-called 'laziness' is actually the instinct engraved in the genes of life, the key is between reason and instinct, which side is stronger." However, this is not evidence that he has life, because we cannot be sure that mechanical life also has a habit of being lazy. ”

"But when it comes to distinction, if you want to make different distinctions about the same thing without any prerequisites, you can only do it with a real mind!"

"The classroom elimination method you used before was the right choice, because in my class, the answers don't come out of nowhere. And even from an objective point of view, this is the only way you can preliminarily determine the answer to this question. Then the association and reasoning can really unfold from this, and this is the so-called 'method', the reason why people don't like to use such a 'method' is because the vast majority of people are afraid of making mistakes, afraid of being blamed and ridiculed, and it is the fear of mistakes, the rejection of 'being ridiculed', that makes us stop. ”

"You can't get to my point of view to determine which one, only uncertainty is from my point of view, because there is a decisive key that has not yet appeared, and that is the image of my interaction with this cleaning robot."

Zhang Nian realized that he knew too many ideas, but he let himself fall into the whirlpool of thinking, so that he didn't really think about the problem from the perspective of a professor.

Dafang said: "From my point of view, I can't determine whether the robot is really alive or not, or maybe it is 'bad' in the first place. So I need to confirm further. But from an objective point of view, the 'bad' option in this class must be 'already filtered out by me', because this is 'Note to the Questioner', and because I won't fake a non-existent image to remind everyone, because this is also a deception. And what you need to know is that there will be a certain life that I will take out, so you only need to rely on the method of elimination, combined with the point of 'distinguishing garbage', you can make a preliminary judgment, and then make associations and reasoning. Of course, it is a good habit to pursue details other than lectures and topics, and if you can really go beyond the scope of students and continue to pursue them, you will definitely benefit a lot. And if I didn't filter, it would be a dereliction of my duty as a questioner, but I've been a competent professor for 50 years. ”

A smile spread across his face after Dafang finished speaking.

'You're a good ass! Intimidating students is still competent, phew! A lot of people complain in their hearts.

"Hehe, hehehe." Wang Chen laughed embarrassedly, he didn't know how to shoot this sycophant.

Dafang didn't care what they thought, and said, "Next, let's take a look at this clip, which is the picture of me determining whether he is an intelligent life." ”

The picture returns to the third floor again, still outside the small shop, and still on the road occupied by defective products on both sides, the cleaning robot is still coming slowly from a distance, but the difference is that the road in front of it is completely blocked by a row of red eyes.

After cleaning the pile of garbage, the robot found a blocked road in the distance, this discovery made its footsteps move forward, paused for less than half a second, the robot's big wooden eyes, seemed to flash a dark look at this moment, only short enough that people could hardly find it, it continued to drive forward.

At the moment when it was about to hit the human wall, the robot stopped, like a real cleaning robot, turned and acted sideways, and when it was about to hit the wall, it turned around and went in the opposite direction, and when it was about to hit the wall, it turned around again, and after two trips, the cleaning robot did what all cleaning robots that acted according to the established program would do, looking for another way.

The cleaning robot turned straight to the straight road.

Suddenly, it found that the road behind it was almost blocked by the red eyes, and at this moment, the big wooden eyes finally showed mood fluctuations, like a wave of water trembling.

With all the red eyes focused, it tried to walk slowly towards the gap that had not been blocked for the time being, but the closer it got to the gap, the more the eyes fluttered, like the eyes of a little boy with tears in his eyes and about to cry.

At the moment when it was about to be blocked, it finally couldn't hold back anymore, taking advantage of all the red eyes staring at it intently, all of them were paying no attention.

Rub!

It suddenly accelerated, rushed out of the gap, and fled.

At this moment, it can no longer control its emotions, although it is destined to not be able to shed tears, but the pair of big watery eyes really seem to be shedding tears because of fear, like a five-year-old boy who ran away because of fear, and the two big Chinese characters that appeared on the small square electronic screen on its chest are more like confirming this.

"Dad~~~!"

With teary eyes and extreme fear, it galloped and fled quickly, and when it was about to pass through the intersection, a person suddenly appeared in front of it.

Boom!

The two collided together.

The cleaning robot, lying on its back and motionless, at a glance will make others feel that it is dead, and it is completely dead, and the two Chinese characters that reappear on the screen on its chest seem to prove it.

Those two words are:

"Broken"

Perhaps it was because the electronic screen felt that this somewhat subjective word was not enough to fully prove the state of the subject to the outside world, so it quickly changed to two other words.

"To be repaired".

Standing in place without moving, Dafang, looking at the cleaning robot lying on the ground, couldn't help but show a long-lost smile, and said to the robot: "Are you afraid?" ”

The robot that has died is obviously unable to react, so in the face of generous questions, the robot has no reaction at all.

Dafang bent down to straighten it over, squatted down and gently smoothed it with his thumb, a scar on its forehead caused by the collision, and said again: "Don't be afraid." ”

At this moment, the pair of big eyes of the machine have regained their blankness, and it is unable to speak without a voice system, and two words are displayed on the electronic screen: "master"

"No, it's a friend." After Dafang said softly, he straightened up and looked down at the robot in front of him.

The word friend made the eyes of the cleaning robot light up, and it looked at the man in front of it, and the more it looked at it, the more obvious the look in his eyes became.

The next moment, the "little boy" whose eyes were full of happiness slowly raised the two mechanical hands towards Dafang, and the electronic screen on its chest, which seemed to never exceed two words, appeared again.

"Daddy"

And then

"Hug"
