What Does a Lotus Root Teach Us About Topology, Humans, and Nezha?

The article uses the lotus‑root analogy from the film Nezha 2 to illustrate basic topological ideas—such as holes, connectivity, and homeomorphism—showing how the human body’s seven major openings correspond to a seven‑hole “lotus” and how continuous deformation can transform one shape into another without tearing or gluing.

Why Euler’s Polyhedron Formula Is the Gateway to Modern Topology

Euler’s polyhedron formula V‑E+F=2, celebrated as the second most beautiful theorem, links simple geometric counts to deep topological insights, inspiring centuries of proofs, applications from dice to soccer balls, and paving the way for graph theory, the four‑color theorem, and modern topology.
