The book features numerous examples of beautiful curves and surfaces often reflected in nature,

plus more advanced computations of trajectory of particles in black holes.

Also embedded in the later chapters is a detailed description of the famous Dirac monopole and instantons.

  1.  宇宙的形狀有可能是S^3嗎   S^3的Ricci curvature怎麼了 我的問題是 Poincare在什麼情境下提出Poincare 猜想
