Lu Zhou spent around ten minutes explaining to his father what Riemann's hypothesis was, and what it meant to prove it. More importantly, how it related to bank passwords…
Of course, he explained it in terms a layman would understand.
If he had tried to explain it in the mathematical sense, he would drain the lithium-sulfur battery in his phone before he could finish explaining.
Old Lu felt nice being able to chat with his son. Later on, he put the call on speaker and Mother Lu also joined in on the conversation with their academician son.
Later on, Lu Zhou realized that maybe his parents weren't concerned about their bank passwords at all, they just wanted to hear their son's voice.
Lu Zhou began to tear up thinking about this.
Maybe it was time for him to go home and visit his family.
But now was not the time for sentimental stuff, he still had something important to do.
