Orion Crest, Series_1

Chapter 63: Interns

　　The time passed quickly.

　　On the 20th of April, Stewart returned from Marseille to Gordon University for a meeting, and after the meeting, he asked Orion to come to his office.

　　As soon as Orion entered, the old man looked over and asked with a smile.

　　"How's the preparation going?"

　　Orion: "Almost there. ...... I hope the professor will be merciful."

　　Stewart: "Almost done? Alright then, I'll just test you on two random questions."

　　Saying that, he drew out a piece of a4 paper and placed it on top of the table.

　　"Here's the pen, take it over and write?"

　　Orion took the pen and paper, looked at the questions on it, and his eyebrows twitched hard.

　　Saying that there were two questions, there were clearly three questions written on the paper.

　　And the promised random test, in which a question does not look like an easy one ......

　　Stewart smiled and asked, "What, can't read it?"

　　" Not really," Orion laughed, looking at the questions, a thoughtful expression appearing on his face, "It just looks, well, kind of not too easy."

　　Stewart smiled and didn't say anything, crossing his legs and waiting for him to move his pen.

　　Not too easy?

　　If this was easy, then what was the point of taking the test?

　　Anyway, he was also an academician, and a graduate student led by an academician, could he be the same as an ordinary graduate student?

　　These questions are not for graduate students, but when he recruits doctoral students, he takes them to examine the level of expertise of those who are interviewed.

　　If you can do two out of the three questions, you are qualified, and if you can do all three questions, you can be said to be excellent.

　　While Stewart was waiting, Orion had already quickly gone through all three questions, and then looked at the first question, which was also the easiest one for him.

　　The first question, examined group theory.

　　However, it was not the mathematical group theory that was being examined, but the application of group theory in quantum mechanics.

　　Because "group theory" as a branch of mathematics was created independently by mathematicians long before the emergence of "quantum mechanics", Unlike Calculus, which was created jointly by physicists and mathematicians. Therefore, for physicists, group theory is a "foreign product", which is difficult to learn and not easy to use.

　　However, for Orion, who was "born in mathematics" and then entered "mathematical physics", it was not so difficult to deal with it.

　　[Explanation of the group theory of 'accidental degeneracy' of energy levels of the hydrogen atom.]

　　The topic is short, but the information is not small.

　　The phenomenon that hydrogen atoms have a higher degree of degeneracy than ordinary atoms is called "accidental degeneracy". However, traditional quantum mechanics does not explain the phenomenon of 'accidental degeneracy', and it was not until the introduction of group theory that the phenomenon was given a theoretical explanation.
