Chapter 176: Not Good Enough
Many of the elders had high education background, they understood the difficulty of the question. This question could be considered hard even for PhD students. Moreover the question was written in English. That was another hurdle for Wei Lan!
Even Jiang Yao was surprised, she had no idea if Mo Li could answer such an answer. “Li Li, since when did you study to such a high level? I haven’t heard you mention anything about it before…”
“I found there is no need to gloat.” Mo Li originally didn’t even want to mention it. However, she needed to do something for her mother. Furthermore, the question was not that difficult for Mo Li, it was rudimentary quantum physics.
This was a question that demanded great logical thinking. As long as one’s mind was clear and logically rigorous, one could answer it. The question was not intrinsically difficult, there were simply many tricks in it.
“The U on the question is written like a V. At first, I thought it represented the scattering of positrons and electrons. But then I realize it shouldn’t be an arrow. Traditionally, the index for summation would have two arrows, one up and one down. Therefore, there has to be one explanation, this isn’t a V, an arrow but a U.”
Everyone thought Mo Li was just rambling nonsense but Elder Lin realized that she really knew what she was talking about.
“Actually, the question is not that difficult to solve. There are two Dirac functions and one integral and that over complicates the problem. Once you remove the integral and one Dirac function, you’ll obtain the Dirac function required to solve the symmetry of the diagram.” Mo Li explained with a smile.
“So the answer is 1/8?” Elder Xu also walked over. He was surprised by the brilliance of this girl. She managed to analyze the question so clearly within the short amount of time.
“Not necessarily.” Mo Li shook her head. “There’s an electron in the lower left corner with momentum p1 and spin energy of s1. It travels in the direction of a straight line until it encounters a wave line. The wave is a photon with a momentum of q. When the electron collides with the photon, its momentum becomes p3 and its spin energy s3…”
“Well done, Li Li. This formula is describing the momentum of a spiral. Once you understand that ab-ba is not equal to 0, the rest should be easy.” Elder Lin and Elder Xu nodded with approval.
At that moment, Wei Lan and her mother just wanted to find a hole to hide in.
There was no comparison at all between the two girls. Mo Li was still a high school student and she could solve the problem a Phd student could not. Furthermore, the way she interacted with both elders were polite but professional. Unlike Wei Lan, she didn’t lose her temper or show any impunity.
Jiang Yao’s face lit up with a smile. In the past, these people had been mocking her using Mo Li’s school results as ammo. Jiang Yao always tried to ignore them. However, all the humiliation she had suffered in the past dissolved in that instant.
Both Elder Lin and Elder Xu were from engineering and science background. They kept praising Elder Mo for the brilliance of his granddaughter. Elder Mo was greatly satisfied.
At that moment, the way everyone looked at Mo Li changed. They didn’t expect that Mo Li was not only not an empty tin can, she was also brilliant than most of her peers. They couldn’t help but wonder if this was a ploy by the Mo Family. They purposely wanted the others to underestimate Mo Li…
“How did Li Li…”
“This is our fault for not seeing the truth sooner. She’s the one with real potential.”
Jiang Yao didn’t put on airs like Mother Wei. She commented kindly, “We are proud of all of our children. They are the pride of our lives.”
Elder Lin looked at Mo Li with a satisfied smile.?This girl has maturity beyond her years. She doesn’t lash out when others look down on her and mock her openly. She also doesn’t become arrogant due to the praises.
However, the more Elder Lin thought about it, the more he felt like his brat at home was not good enough for Mo Li!
