Chapter 889 888 [Eat Meat]

They hid from the bombing until about three o'clock in the afternoon. Teachers and students returned to the school building one after another, and Zhou Hexuan followed him to find a classroom to observe.

Although it is almost the end of the term, many teachers continue to teach as usual and don't care about the final exam at all. Especially in the Chinese Department, the teachers of each subject are not very particular about exams, and they can just hand in an article at the end of the semester.

It seems that Zhu Ziqing is the most strict in the entire Chinese department, requiring students to take notes in class and take exams seriously at the end of the semester.

Of course, departments such as science, engineering, medicine, and law are still very strict. One time, a group of freshmen cheated and were punished by Principal Mei's personal order.

Today, Zhou Hexuan was sitting in on logic taught by Jin Yuelin. This is a compulsory course in the Faculty of Liberal Arts. Just like advanced mathematics in the Faculty of Science, it can drive students to the point of ecstasy.

Jin Yuelin is tall and strong. He wears the only jacket in the whole school. If it is winter, he wears a windbreaker. He is absolutely stylish. Unfortunately, his hat and glasses ruined the overall image. The brim of the hat was very low, covering his entire forehead. The glasses are even weirder. One lens is white and transparent, and the other lens is black sunglasses. It seems that opening the sunglasses will release the seal of the Sharingan.

This is not a special hobby. Hats and sunglasses are used to block light, because Jin Yuelin has one eye that is afraid of light.

Jin Yuelin's class has the charm of sitting down and talking. He never stands up to give lectures, nor does he look at the students below. He always sits on the podium with his head lowered. He only stands up when he needs to write on the blackboard occasionally.

Zhou Hexuan's entry into the classroom caused a sensation, but the sensation soon stopped because Jin Yuelin had already started class.

Jin Yuelin lowered his head and said in a magnetic baritone: "Today we will talk about the basic concepts and propositions of the logical system. Let's talk about atoms first. Atoms are objects of the logical system, not logic. The object of logic is necessity. , the logical system is just a tool that uses certain atoms to express necessity... First, class. The so-called class here is an ordinary class, such as human, mountain, water, etc. Class has the concept of class, such as Human beings have the concept of human beings. Most classes have members of the class. For example, humans have Zhang San and Li Si... There are two special classes among the classes of atoms in logical systems, one is the zero class and the other is the whole class. The zero class does not have Molecules, all molecules are members of all categories. Generally, '0' represents zero category, and '1' represents all categories. Do you still remember the general formula of system cadres listed in paragraph 3 of Section A, Chapter 1 of this article? The five basic proposition functions are as follows..."

As he spoke, Jin Yuelin suddenly stood up and wrote a general formula on the blackboard with chalk: (彐z)·(a)·a?z=a.

What the hell?

Zhou Hexuan looked a little confused. He didn't understand logic at all, let alone logical symbols and general formulas.

As for the liberal arts that was promised, how can it be made the same as high mathematics?

Jin Yuelin drew two more intersecting circles, marked a and z respectively, and said: "z represents the zero category. This basic proposition means that the zero category or a is equal to the a category, and it also means that the zero category is included in any category."

Okay, Zhou Hexuan understood it now, a very simple logical question.

People may think this thing is useless because it has been integrated into people's basic thinking mode. But when logic was just founded, it had guiding significance for any science.

A student suddenly raised his hand and said: "Sir, why do we have to talk about zero-category love, and how can we determine that certain objects must be similar to zero-category? The 'ghost' is similar to zero-category, but Can water give away the existence of ghosts?"

Jin Yuelin seemed to be confused by this question. He thought for a while and said, "Classmate Lin Guoda, let me ask you a question: Mr. Lin Guoda is perpendicular to the blackboard. What does this mean?"

"Uh..." The Guangdong student named Lin Guoda was speechless.

The conversation between the teacher and the student was very interesting. Lin Guoda questioned the correctness of the zero-class concept and used ghosts as an example to doubt whether there is a real zero-class concept. Jin Yuelin asked: Lin Guoda is perpendicular to the blackboard. What does this mean?

Lin Guoda naturally cannot be perpendicular to the blackboard, which is similar to the zero-category concept. However, from a grammatical and logical point of view, this sentence is correct. There is no way to falsify the student's perpendicularity to the blackboard, just like it cannot be proved that ghosts must not be The same as existence or existence.

Zhou Hexuan almost laughed out loud. He actually witnessed the famous "Lin Guoda perpendicular to the blackboard" incident.

But Zhou Hexuan couldn't laugh because Lin Guoda would soon swim and drown.

This classmate Lin Guoda likes to ask questions very much, and he always uses the awkward Cantonese and Putian to ask some weird questions, which often makes the classmates in the class burst into laughter.

Jin Yuelin obviously liked Lin Guoda very much, until one day, he said in class: "Lin Guoda is dead, unfortunately."

get out of class ended before he knew it. Zhou Hexuan walked up to Lin Guoda and warned: "Student Lin, don't go swimming in the river. That kind of behavior is very dangerous."

Lin Guoda looked confused and subconsciously agreed: "Ah... okay."

At this moment, a pig's roar suddenly came from outside. The students who originally wanted to communicate with Zhou Hexuan ran out to watch the fun. Mr. Zhou was not as attractive as the big fat pig.

"Bah bang bang!"

Zhou Hexuan clapped his hands and said with a smile: "Students, today I bought ten big fat pigs, and I will eat pork with the teachers in the evening! Everyone eats with an open stomach, and there is enough rice!"

The students were stunned, swallowed collectively, and then cheered: "Long live Mr. Zhou! Long live the big fat pig!"

Jin Yuelin pointed out very seriously: "There is something wrong with your logic. Long live Mr. Zhou, and long live the big fat pig. Then Mr. Zhou may be the big fat pig."

"Hahahaha..." the students laughed.

Ten big fat pigs were bought to the school by Sun Yongzhen, which immediately caused a sensation in the whole school. At least nearly a hundred future academicians came to watch the pigs being slaughtered.

The three floors inside and outside were crowded with people. Many professors moved over with small benches and concentrated on their research while listening to the sound of pigs being slaughtered.

Sun Yongzhen not only brought back ten fat pigs, but also bought several large boxes of cigarettes. Just looking at those cigarette packages, smokers who have been without food for several months have their eyes turned green, daydreaming about the magical days of eating pork and smoking at the same time.

"Kill the pig, kill the pig!"

The children of the teacher's house were running wildly all over the floor, laughing and playing in groups. Some children ran to ask their parents: "Mom, is the New Year celebrated today?"

Zhou Hexuan was also laughing non-stop, and the scene in front of him made him very happy, because everyone's joy was so real and pure.

The teachers instructed the students to move all the desks and chairs to the open space. When it was getting dark, some boys appeared carrying wooden buckets. There is only one dish in the bucket, pork roasted with kidney beans. The remaining pig blood, pig intestines, pig heart and lungs, etc. will be given to the teachers to take home to improve their meals.

Since electricity bills are very expensive and there are frequent power outages, torches were lit in the open space, and the flickering light was full of smiling faces.

Mei Yiqi was the first to speak: "Teachers and classmates, Mr. Zhou invites everyone to eat meat today. After eating meat, don't forget to study and serve the motherland. Come, let us sing the school song of Southwest Associated University together. I Let’s get started…”

The teachers and students sang in unison while looking at the roasted pork in the barrel:

"The long march of thousands of miles ended with the palaces of the Five Dynasties.

Stopping for a while, Hengshan and Xiangshui are parting again.

Jueqiao transplants the dry matter, and the blood of Li Yuan is sprinkled all over Jiuzhou.

Playing the jakes and chanting the strings in the mountain city, the love is so deep!

A thousand years of disgrace will eventually become a thing of the past; to revive the industry, we need outstanding people.

There are only three households in one city, and it is difficult to lose a strong heart.

I am deeply worried about the new nation's movement during the difficult times, but I am tempted to endure and look forward to the wisdom of the past.

After the Japanese invaders are driven out and Shenjing is restored, return to Yanjie! "
