"What is Riemannian geometry?" asked Zuo Xinli.

Although her mother was a math teacher, she really didn't know that much.

Li Yi said: "Riemann geometry is a geometric theory proposed by the German mathematician Riemann in the mid-19th century, which can be regarded as a generalization of Euclidean geometry. In physics, Newtonian mechanics can be roughly said to be based on Euclidean space, while space-time in general relativity is a Riemannian manifold. To study general relativity, you need to know Riemannian geometry before you have to. ”

Zuo Xinli blinked her eyes and slowly spit out three words: "I don't understand." ”

"It's so hard, you don't have to understand it yet. Tong Gexiao modeled his daughter's head, and said to Li Yi: "You said that Xinli's two classmates are learning Riemannian geometry?

Li Yi said: "There is nothing impossible in the world, as long as we are willing to work hard. I'm not much older than them, and I'm not the same as solving the Riemann conjecture and the Goldbach conjecture? ”
