"Please turn the textbook in your hand to the second subsection on page 39......"

An instructor wearing a pair of gold-rimmed glasses is holding a physics-related book in one hand and teaching his students in a multimedia classroom.

At this time, the instructor looked very young, with a concise ponytail tied with a strand of red rope on the back of his head, and the whole person looked like a fairy character who came out of the book, looking like a teacher in the art department, without the style of an ordinary physics professor and an old pedant.

Except for a few girls in the classroom who have been looking at him eagerly, most of the rest of the boys are quite lacking in interest, and even some of them are sleeping directly on the desk.

"Then, after reviewing this section, let's move on to the ...... on page 45"

"Purr...... Purr ......"

I don't know if it's because the classroom is too quiet, in addition to the voice of the instructor himself, there seems to be another voice coming to stir up the situation......

A student who was asleep on the second-to-last row of desks snored like thunder, and almost instantly, most of the students in the classroom turned their heads to look at the snoring "warrior" with a little amusement.

The student who accompanied him stabbed the sleeping one sitting next to him with his elbow, and the snoring student shook his body and woke up suddenly, only to find the entire classroom, including the professor who was lecturing, staring at him with a smiling expression.

The student opened his mouth, and cold sweat trickled down his head at once, after all, to be admitted to Tiandu University, at least there was no shortage of observation, and he knew what was going on almost the moment he woke up.

"Old ...... Teacher...... I ......"

"It looks like the content of my lecture is too boring......" The instructor hooked the corners of his mouth, and did not pursue the meaning of this student, but said with a little self-deprecation: "Your seniors in the past, probably until the third class, there will be a presence of sleeping in class...... This year's sixth class just appeared, which is very face-saving for me. ”

The instructor's witty remark clearly provoked a burst of laughter, and then he continued: "But...... There's no way, professional knowledge is always boring, you are still just freshmen, and the knowledge you can get in touch with is still relatively basic, and these knowledge are for you who can be admitted to Tiandu University with your own ability...... It's not too difficult, and the only drawback is that it's just boring. ”

"However, with the gradual deepening and progression of knowledge, as a physics student, you will always come into contact with more and more advanced and unfathomable physical theories.

"Some of you may give up because you are weak-willed, you may stop somewhere because of lack of talent...... Or is it really suitable for physics, fight a bloody way from the pile of corpses of countless fallen predecessors, and finally bear your own sweet fruit, of course, even the proud sons of heaven here, such people are not one in a hundred. ”

"However, it is foreseeable that this four-year professional physics course will become a nightmare for most students in their lives......

Seeing that most of the students were frightened by their descriptions, a hint of cunning flashed in the instructor's originally peaceful eyes, and he changed his words: "However, before you go through such a terrifying nightmare, you might as well listen to me talk about some interesting topics and relax......"

"Although the seemingly delicious fruits of the temple of physics are often accompanied by sharp spikes...... Most of the professional physics theories are also boring, but the inferences and hypotheses to which these boring formulas point are often dressed in a charming cloak – and this is what we physicists are fascinated by. ”

"How did the universe come into being? And for what reason will it be destroyed? ”

"Is it really possible to reverse time faster than the speed of light?"

"Do parallel universes exist? Are we the only intelligent life in this vast universe? ”

"These fascinating questions are like juicy flesh wrapped in the seed of truth, attracting the attention of every seeker who wants to seek the truth."

"So, did the professor find the answers to these questions?" A voice appeared suddenly, causing the instructor's mind to be slightly confused.

He looked fixedly, and the owner of the voice that raised his hand to ask questions was a rather immature-looking freshman boy, he was wearing a very plain plaid shirt and a pair of thick black-rimmed glasses, but his skin was very fair, which contrasted strongly with the color of the black-rimmed glasses—the standard appearance of a weak and good student, the instructor thought to himself.

After a deep sigh, the instructor slowly replied, "No, no, this classmate...... There is no limit to the truth in this world, but not the energy of man. ”

"Our seemingly thousands of years of splendid civilization is not worth mentioning in the face of such a huge scale since the birth of the universe, and the truth we have mastered is actually just a drop in the ocean...... What's more, an individual whose life is short? ”

"A person's life span is too short to know the answers to all his curious questions, what we can do is to intercept a very small part of these many questions as our own research direction, and this small question may even cost us a lifetime ......"

"I ...... too It's just one of these sentient beings, and he still hasn't figured out a single problem. ”

"And you, you...... Maybe some answers will be found eventually, but until then...... You have to find your own problem first. ”

……

After class, the instructor was packing up his courseware, and after he was ready to pack up, he left directly.

But the boy who asked him a question in class stopped him: "Professor." ”

The instructor turned his head and looked at the boy inquiringly.

"Sorry for delaying your break, but ...... I'm interested in what you said about the wormhole. The boy smiled shyly and slowly said what he meant: "Do you have time to talk to me a little?" ”

"Of course, I'm welcome." The instructor was slightly surprised by the student's enthusiasm, but nodded happily, "I know you...... You always sit in the first row in every physics class, and the notes are the one that takes the most seriously. ”

"Do wormholes really exist? Professor, can we really travel through time? ”

The smile on the instructor's face slowly faded, replaced by a trace of trance, he subconsciously touched the red rope tied to the back of his head, and said lightly: "I want to ...... It should exist, or ......"

"In that case, why has it been so long, and still no one has been able to discover the wormhole?" The boy asked with interest.

"Students, many times, when we think about a macro problem, we always make a mistake - look at the problem from the same macro perspective." The instructor patiently explained: "For example, some grand propositions about the universe, time and space......

"Interestingly, however, the answers we want to get at the macro level are often hidden in the micro level......

"A wormhole that could be passed through by an entire human may not exist, but that doesn't mean that the wormhole itself is nonsense......

"Maybe in the microscopic world, elementary particles can already travel freely in different space, space and universe, maybe too?"

"And this is the quantum world."

"Quantum World ......" The boy's eyes gradually brightened, and he said excitedly: "Thank you, professor!" I might ...... Found my question! ”

The instructor looked at the immature big boy in front of him with some amusement, his eyes softened, and he said softly: "Don't decide the second half of your life so quickly, you still have a long way to go." ”

"Thank you, Professor!"

The boy was about to leave, but for some reason, the instructor stopped him who was about to turn around and asked, "Hey, classmate, what's your name?" ”

The boy was stunned, then smiled heartily and said seriously:

"My name is ......"

"Bai Xuyan."
