Chapter 502: Chapter 300 "Microscopic World: Particle Boundary Theory"
"Zhao Yi, why are you here in the class? This is clearly a class for mathematics department..."
"Why is he here!"
"Did he sit through the entire class? You’re right, I recall seeing a student entering from the back door earlier. Could it be him..."
Gao Yihua was mentally broken.
For the past few years, he has been teaching physics in the School of Life Sciences. He never thought he would encounter a ’superior student’ Zhao Yi, a top math talent, who managed to bring significant contributions to the European nuclear organization, even addressing and resolving the challenge of discovering new particles right at the test site.
With this achievement alone, he is recognized as a top physicist in the world, even those in the industry are aware that his method heavily involves computational methods.
But does it matter? Results are what matter most.
Even if he employs knowledge from unrelated disciplines such as biology, as long as it solves important physics problems, his proficiency in physics will certainly be recognized.
This is why Gao Yihua felt he simply couldn’t teach anymore.
There was an internationally renowned physicist in the classroom. He did not know how to proceed with the lessons. He barely made it through the remaining classes, and Gao Yihua ended up in despair. He elected to apply to become a teacher in the School of Sciences, far away from the School of Life Sciences, preferably without any connection at all.
This semester, Gao Yihua felt completely relaxed.
Everytime he was in class, he would reminisce about his experiences from the previous semester, and a quick glance around the classroom always lifted his spirits.
Now...
Is it happening all over again?
"That guy!"
"He’s back!"
Gao Yihua didn’t know how to react. He was rooted to the spot on the podium for a moment. Noticing the surprise in the students’ eyes, he snapped back to reality and knew that he couldn’t let Zhao Yi’s presence disrupt regular classes.
Not that he is particularly dedicated, but Zhao Yi sat silently in the back row, without causing any distraction to others.
As a teacher, he couldn’t let his personal feelings interfere with the flow of the lesson.
So, carry on!
Gao Yihua gritted his teeth and tried to ignore Zhao Yi’s presence, pretending he hadn’t seen anything. "He’s not here! He’s not here! He’s not here! He’s not here..."
Of course, it didn’t help.
Gao Yihua’s mentality was still affected. His relaxed demeanor and carefree attitude was gone; his face grew more serious. He instinctively began to explain the content in a more detailed and deeper level.
"Whether other students understand or not doesn’t matter... I must not be looked down upon!"
That was what Gao Yihua was thinking. It felt as though he was going through a knowledge inspection.
...
Off-stage.
Zhao Yi supported his chin and listened attentively, following Gao Yihua’s explanations and delving into deep thought. Of course, he knew about parity non-conservation.
This was the research of the famous Chinese physicist and Nobel laureate, Yang Zhenning.
Parity non-conservation refers to the asymmetrical motion of mirror-image materials under weak interactions.
This research was later verified by Wu Jianxiong using Cobalt-60.
Before 1956, the physics community always believed that everything in the natural world was mirror-symmetric. Whether it was the strong interaction or weak interaction, all would comply with the principle of mirror symmetry.
The understanding of ’parity’ is that the mirror image of a particle has the same properties as itself.
In 1956, physicists discovered that theta and tau mesons had identical spin, mass, lifetime, and charge. Most people thought they were the same particle, but when a theta meson decayed it produced two pi mesons, whereas a tau meson decayed into three, which indicated they were different particles.
A contradiction appeared.
That year, Li Zhengdao and Yang Zhenning, after meticulous study of various factors, boldly asserted that tau and theta were completely the same particles (later named K mesons), but their motions under the circumstances of weak interaction were not necessarily the same.
Simplistically, two same particles, when mirrored against each other, had different decay patterns inside and outside the mirror.
In scientific terms, the "theta-tau" particle does not conserve parity under weak interaction.
When first discovered, the "theta-tau" particle was considered as a special exception. Still, people were reluctant to give up the belief that the micro-particle world as a whole conserved parity. Shortly thereafter, Wu Jianxiong, also of Chinese descent, cleverly confirmed "parity non-conservation" through an experiment.
Ever since, "parity non-conservation" has been recognized as a fundamental scientific principle of universal significance.
"Parity non-conservation" is a significant discovery that subverted scientists’ comprehensive understanding at the time.
On this basis, Yang Zhenning won the Nobel Prize in physics.
But that was just the beginning.
As the research on quantum physics progressed, the physics community discovered many asymmetries in the microscopic particle world.
"Parity non-conservation" came to be universally accepted and popularized.
The symmetrical laws of the physical world of particles began to shatter, and the world was proven to be fundamentally imperfect and flawed. freeωebnovēl.c૦m

Gao Yihua’s explanation was detailed and profound. Even more so, he began to list formulas and explore some of the classical types of particle asymmetry during the lecture.
This type of content was definitely advanced, even severely so.
At the undergraduate level, there was no need for them to understand this content. The substitution formulas used and some of the content relating to particle physics were beyond their comprehension. There were very few in the classroom who could understand...
