Chapter 607: How Nuclear Power Unites!
Grass?
Lu Shin?
Idol!
Zhang Zhongqing almost didn't drop his glasses on the floor when he saw the person standing up.
The thought of this big man sitting in his classroom listening to a half-day lesson made him feel so surprised and surprised, it was like winning a lottery ticket. Surprisingly, I didn't notice at all. Happily, we can brag when we go out, and we're the ones who taught the Noble Prize boss.
However, although Zhang Zhongqing's heart is full of emotions, the ark feels nothing.
The classroom itself is also one of the venues for academic exchange.
Previously in Princeton, he used to let his students go up and speak for themselves.
At least, in his view, communication academics were status-differentiated and honorable.
“Professor Lu, please.” Professor Zhang immediately made a gesture, respectfully giving way to the podium.
“Don't be so polite, I just happen to have an idea. ”
Watching his humble move, the ark laughed embarrassingly.
Continuing the condom is too late.
Besides, he's not a condom lover himself.
Standing in front of the blackboard, the ark picked up a piece of chalk.
“Such problems are not solved by undergraduate students and require a deeper grasp of generalized letter analysis in addition to a deeper knowledge of quantum chromodynamics. ”
Paused for two seconds, the ark continued, “But it's not as complicated as you think. ”
Speaking, the chalk in his hand was printed on the blackboard, and the ark counted as one side of the board book.
“From the field theory, make a Feynman diagram and use the Feynman rule to calculate the scatter amplitude to get...”
[iM = (ig ² | p '-p | ² + mφ ²) 2m ^ ss' · 2mδ ^ rr ']
……
“Where mφ represents the mass of the respective boson, g is derived from the coupling constant in the interacting Large quantity. Combined with Professor Zhang's previous calculation steps, V (Q) can be obtained by scattering cross-section...”
[V (q) = -g ² (| q | ² + mφ ²)]
Written here, the ark stopped the chalk in its hand and looked back at the staircase classroom, or at the students who were forced or listening seriously, laughing and talking.
“All of this is fairly simple, but some tips will be used for the next step. ”
Students: "…”
MMP!
What's so simple???
Zhang Zhongqing, standing next to him, was also blind.
It's not that he doesn't understand it, but that he can't believe that someone could actually pull these things out of the field in such a short time.
Doesn't this guy have to spend time overthinking his calculations?
If that's true, that would be horrible...
Without making any stops, after that sentence of the ark, he turned to the blackboard again and said in a derogatory manner.
“Do the Fourier Inverse Transform on it! ”
The noise of the chalk rubbing blackboard is getting faster and faster, and Zhang Zhongqing's expression standing next to him is getting more and more shocking. As for the students under the stage, they looked at the blackboard blindly, even if they had already turned the textbook over a long time ago, and faced the complicated computational process, they looked overwhelmed.
At this moment, however, the Ark has not noticed their faces and is completely immersed in its own world.
Admittedly, these are some very basic things, but there's just not enough foundation to show up on a routine or exam.
However, with the in-depth reflection on these fundamental issues, as the number of steps on the blackboard grew, the light in his mind became clearer and clearer.
Why can strong interactive forces only work at very short distances?
Or in other words, what makes a nucleus form an atomic nucleus only at very short distances?
The answer is obvious…
……
[V (r) = -g ² 4πr · e ^ (-mφr)]
The chalk in his hand stopped, looking at the formula on the blackboard, and the ark opened slowly.
“Electromagnetic interactions exchange photons with zero mass, so for electromagnetic interactions, the ratio of V to 1R is positive. ”
“Nuclear power is provided to the nucleus by a factor that acts between the nuclei, with a mass of about 200MeV, and with the introduction of calculations it can be estimated that only the distance term is at the order of minus 14 times of 10. Nuclear forces acting between the two protons can counteract electromagnetic repulsion between the protons and produce a fusion reaction. ”
The applause starts in the first row.
It spreads backwards like a wave slamming on the shore.
Professor Zhang, standing next to him, also accidentally clapped his hands.
For most students, it's probably just a fun look.
But for him, he saw a simpler solution to the nuclear distance… at least two simpler solutions than he remembered.
Incredible, these were all done on site in less than 10 minutes...
The shock in his heart at this moment, I'm afraid, is only clear to him.
At the same time, on the podium.
Though the classroom has been filled with applause, the ark standing in front of the blackboard is still immersed in its own world at this moment, so completely unnoticed when the applause stops.
For the simple question before, the calculation is over.
However, that was not all he was thinking about.
According to the views in quantum field theory and quantum chromodynamics, the four fundamental forces and traditional particles can be unified.
For example, in different space-time locations, the components of the electric field can be constructed as non-exchanged operators, and when constructing the Hilbert space in which these operators act, traditional particles - such as electrons - can be reinterpreted as quantizing the Dirac field.
And then the difference between the field and the particles disappears.
Can a simple mathematical form, like Weinberg-Salam-Glashow's unified theory of weak electricity, describe strong interactions in some unified way, and unify them with electromagnetic forces?
Answering this question will not solve the miniaturization of controllable fusion, nor will it bring any degree of innovation to existing controllable fusion technologies, but intuition tells the Ark that if the problem can be solved theoretically, it may provide a clue, or a way of thinking, to solve it...
Of course, it's not easy to do that.
For example, there is a typical problem with strong and weak interactions…
The class bell rang, and the ark was still standing there motionless, seemingly thinking about something.
Zhang Zhongqing did not respond to the Ark boat, and Zhang Zhongqing did not want to announce the end of the class without permission, let alone disturb his thinking.
It's been about ten minutes.
Staring at the simple formula on the blackboard, the ark suddenly seemed to speak to itself.
“How can the existence of quality gaps be explained in mathematical language? ”
When he heard the question, Zhang Zhongqing stunned consciously, and then blushed. He seemed like a student for a while.
“... this, I really don't. ”
“I didn't ask you, you definitely won't...”
Speaking to himself, he left behind a blackboard formula, and the ark turned away from the classroom, leaving a stunned professor and student.
No one can answer that question.
After all, this is one of the most difficult propositions for unified field theory in particle physics today.
Also internationally recognized in mathematics, one of the seven major millennium challenges…
