A week had passed.
Edward was indeed a knowledgeable elder, and Zhao Yi had learned a lot from him about quantum physics, string theory, and some microscopic theories.
Edward also gained a lot.
His direct gain was a more intuitive understanding of the three-dimensional shaking waveform, and he also discussed and calculated some auxiliary fields of string theory with Zhao Yi.
For a theoretical study that only exists in theory, a week's time is really too short.
Edward felt somewhat unsatisfied. On the last day before leaving, he invited Zhao Yi to Princeton University again, "You can study for your undergraduate degree at Princeton, quickly earn your bachelor's, master's, and doctoral degrees, and at the same time, the university will offer you a full professorship."
"Princeton University is a paradise for mathematics. You'll like it there."
Zhao Yi declined directly, "I'm sorry, I like my current environment and I have no plans to go abroad for the time being."
"What a pity!"
