From Space Idiot to Professor - From Space Idiot to Professor chapter 25

25 – Interview (4)

“It is the field that supplies energy to the light bulb.”

“Jean?”

“Yes. “An electromagnetic field.”

I wrote a line of equations on the blackboard.

“This is a pointing vector.”

“… Pointing vector?”

“It is a vector related to energy transport in electromagnetic fields.”

The two interviewers looked at each other and shrugged their shoulders.

Both of them didn’t look good.

Except for one person.

“Can you explain what a vector is?”

The interviewer sitting on the far right nodded with interest and asked.

“Of course.”

I answered confidently.

“A vector is a physical quantity that has both magnitude and direction. However, this is not an accurate definition. More mathematically, we can say that elements in a vector space are vectors.”

“Uh….”

“But this is not our concern. In physics, a vector is defined like this: “A physical quantity that has a coordinate transformation such as position.”

“Hey.”

The two interviewers frown as the conversation continues.

But it was too late.

You cannot stop my explanation, which has already gained momentum.

“Back to the point, electric and magnetic fields are fields. The field is a function that has a position vector as its domain. Information on electric and magnetic forces can be corresponded one-to-one for each location. And from this fact we can know the direction in which electromagnetic energy is transported at any point. This is where pointer vectors come in.”

I explained calmly. And then I finished drawing.

Draw electric field lines.

Magnetic force lines that change accordingly are added.

A complex and subtle field was drawn on the electronic whiteboard, which had only a few lines of formulas.

It was a difficult process to draw this quickly and accurately, but it didn’t take me that long.

Why?

“Oh, no, that…” .”

Because I used both hands.

After I finished drawing the picture, I turned around and said.

“This is a picture showing the strength and direction of the field.”

Then I looked around, and the expressions on the two interviewers’ faces were not very good. He is frowning like a child who is afraid to poop.

What is it? Is the picture wrong?

No, I didn’t think so. The picture was drawn properly.

“Heh heh heh.”

In the meantime, only the interviewer sitting on the right laughed.

I had a hunch.

That person is different.

At least the atmosphere he gives off is completely opposite to that of the other two interviewers.

The appearance of a professor, not a teacher.

Having lived as a professor for half my life, my radar is quite accurate. At a glance, you can distinguish between scholars and non-scholars.

So even if I didn’t know the face, I could recognize it.

That person is definitely the person I am looking for.

“… ….”

You have to look good to that person.

I caught my breath.

After finishing writing, he put down the electronic pen and continued his explanation.

Let’s see, how far did we go?

“Pointing vector….”

We made it there.

“The direction perpendicular to the electromagnetic field is the direction of the pointer vector. Energy is transferred in this direction. The way to figure this out is simple. “It means using a right-hand reference frame.”

“Ha, student.”

“What is the right-hand reference frame here? Now, this is a precept based on the way you hold your right hand like this.”

“Ha, student. That’s enough. Now stop….”

“Wrap your four fingers so that they point from the electric field to the magnetic field, and take your thumb in the direction of the pointing vector. Now, no matter where you calculate it, the direction of energy is concentrated towards the light bulb. And….”

“Hey, student?”

“… The speed of propagation of these electromagnetic fields is the same as that of light. Let’s say I place the battery and switch here in Stellarium, and the light bulb in the northern Adelvine system. Ignoring the existence of a black hole in between, the straight-line distance is 80,000 light years, so if I turn off the switch here, the light bulb will only turn on 80,000 years later…….”

“Student-!!”

“Yes, yes?”

I was so immersed in the explanation that the interviewer silenced me.

There is still some explanation left.

“If you made it that far, it’s okay. “It’s full and overflowing!”

“But still less…” .”

“It’s okay!!”

The interviewer waved his hand desperately. It seemed like the interview time was almost up.

“Didn’t you say you didn’t do any good deeds a little while ago?”

“Yes, I didn’t.”

It is true that it was not done because there are no records.

“I think what I just explained was outside of the Academia curriculum?”

Ah.

That’s right.

This wasn’t a graduate school interview.

I was trying to impress the interviewer sitting on the far right, so I ended up giving a needlessly long explanation.

“…… “I was curious, so I looked it up personally.”

I covered it up appropriately.

The two interviewers were wiping their foreheads with handkerchiefs. Sweat was pouring down from their foreheads like rain.

It’s strange. I don’t think I turned the heater on that hard.

Anyway, I returned to normal and prepared for the next question. After this, they will probably ask about future plans or motivation for applying.

It was when I was repeating the prepared lines in my head.

The interviewer sitting on the far right pointed to the blackboard and asked.

“That pointing vector, do you know how it is derived?”

“Of course.”

I can’t stand the induction process.

[“This guy was even greater than he looked. “They don’t even belong to our army, but they made two humans crazy at once.”]

[— The ‘God of Wisdom and Curiosity’ applauds you.]

[— We received 5,500 pron donations!]

I laughed out loud as I looked at the message floating in the air.

“Holy sh*t.”

The interview was delayed.

Being a too-much talker in front of the interviewers must have created a negative perception.

Even if you don’t watch it, it’s a video.

I fell.

Even if I received a huge amount of Pron, I had no use for it.

If I were to leave Stellarium like this, there was no other way than to give birth to a foreign child.

Could it be that Cartesia gave this to him as a wedding expense?

[— The ‘God of Wisdom and Curiosity’ laughs softly.]

Do you really need to prepare your mind?

“… ….”

No, I don’t know yet.

Jininsa Daecheonmyeong. I’ve done everything I can anyway, so all that’s left is to wait.

As I waited anxiously in the waiting room after the interview, other students began to come in one after another.

“How was the interview?”

And among them was Zernia.

Zernya saw my sh*t-chewing expression, then sat down next to her with an alluring smile.

“I can tell just by looking at your face.”

“… ….”

“So, I told you, right?”

It only takes a moment to turn upside down.

The moment I heard those words, I thought I wanted to turn this whole place upside down. I thought I knew why Adelbein’s blood was described as having a dirty personality in the novel.

“It’s a shame.”

Zernia grinned. She seemed certain that I would not pass.

“Thank you all for your hard work. “I hope you pack your bags and go home.”

I wasn’t sure, so the supervisor’s stereotypical greeting didn’t sound pleasant to me. I thought I would at least be happy when the entrance exams were over, but now I only felt empty.

Er, I don’t know. Whatever happens, happens.

I packed my bag and left. Then, I was in a hurry so I turned around to the bathroom.

“Oh my.”

There I was able to reunite with an unexpected person.

“Heh heh.”

This was the interviewer who asked me a series of questions about my major during the interview.

“You’re the student from earlier.”

I smiled sheepishly and lowered my head.

“It was a fun time. Well, it didn’t feel like an interview at all. “hehehe.”

He looked in the mirror and straightened his dress shirt. His sloppily dressed appearance made him look more like a hermit who had detached himself from life than a teacher or professor.

“The evaluation itself ended on the spot. “The student’s decision to join would probably have been decided on the spot.”

“Yes….”

“Still, if there’s something you want to say to the old woman… “I said it was too difficult when explaining the Poynting vector earlier.”

“… Did you?”

“Yes. “Practice developing intuition before formulating.”

The interviewer pointed out the disappointing parts one by one.

That level is far away. Insight that could never come from Academia teachers who only superficially studied science.

This is the speech of an expert.

“If I only understood the physical meaning, I wouldn’t have asked about the induction process. hahahaha. When I mentioned that, it was quite nice to see the rest of the interviewers freaking out and trying to run away….”

“… hahahaha.”

What I meant was that I had to speak briefly and concisely so that people wouldn’t get bored.

Tak, thak.

After washing his hands, the interviewer lightly shook off the moisture and continued speaking.

From noble mtl dot com

“Student, you said your name was Idel, right?”

“Yes.”

“Do you know why the student’s motivation for applying or future aspirations were not asked during the interview?”

Motives for applying and future hopes are almost always asked questions.

I knew that and prepared, but in reality, I only passed the personality interview and ended up taking the major interview.

I thought the reason was ‘because the time limit for the interview was not enough.’

“Wrong.”

But that’s not true.

“I didn’t ask because there was no need to ask.”

***

When the long entrance exam schedule was over, I lay down like a ghost.

“I’m going to die.”

“Have you not been overworking yourself? “It’s natural that you’re in pain now that you’ve relaxed.”

Even as times advance, the human body has barely changed. Transhumanism or something like that might come up, but it seems like the author didn’t think of it. The genetic level of humanity was the same here and in reality.

For this reason, the mechanism by which humans acquire diseases was the same, and the way they took rest was not much different.

Sonia said as she changed the wet towel for me as I lay on the hospital bed.

“Let’s give birth quickly.”

“What can you give birth to?” .”

“Excuse me, I think it’s time to replace my vocal cords. “Get well soon.”

The fever was not normal. Even if I just put a wet towel on my forehead for 10 minutes, it felt hot right away.

Sonia put down her wet towel again. She drained the water and placed her hand on my forehead.

What a shame.

“It is difficult to measure accurately.”

Shakily, Sonia raised her body.

She pressed her own forehead against mine. It’s cold, but feels warmer than steel.

“As a robot, he arbitrarily places his forehead on a person’s head.”

“Are you belittling my care as a human being?”

Sonia looked down at me with her forehead still pressed against hers. They were so close that their noses could have touched each other.

“Get out of the way.”

“… ….”

“It’s heavy, so get out of the way…” .”

“39.8 Degrees.”

Sonia then lifted her forehead and grabbed her wet towel.

Snap! Unlike before, he put a towel on my head without any sincerity.

“They both do different things.”

And there was someone watching it from beginning to end.

“When did you two become so close?”

It was Seti. Seti approached us, looking at us disapprovingly.

Tuk.

She held out a rough letter in front of me.

“This was left in front of the door.”

“What is it?”

“I don’t know either. The recipient just had your name on it. “Someone sent a crudely handwritten letter in a time like this.”

“Could it be a love letter?”

“What? Love letter? Phew, f*ck. Huh, huh, huh… ! Ahahahahaha!!”

Seti, who was getting angry, simply ignored her and opened her letter.

And there, something completely unexpected was written there.

[Additional interview available. It is not mandatory, but if you wish, please come to the address below at any time.]

[— Physics professor of interest to you]

Now I can be sure who the person I met at the interview room that day was.

Okay….

There is no one who pulls pranks like this other than him.
