"I'm not interested in philosophy, but I'm interested in mathematics. Can you tell me how it relates to Mathematics?"Gu Xiangwen's eyes sparkled when he was young, it was the kind of expression he would have when he talked about something he was most interested in.
"Kevin, I've written a popular science book about this. You can take a look if you have time."
Gu Nianzhi suddenly woke up from her dream.
She remembered now.
Lu Jin had found her a pile of information about the book of changes and Hundun Mathematics, and one of the books was the popular science book written by Professor Vanderbilt.
She rubbed the space between her eyebrows, thinking that the Gu Xiangwen in her dream was not her father, Lu Jin.
Because the books were from this world, not the other world.
When Lu Jin had given her the information, he had said that the books in this world were not bad, but she had never seen them in that world.
