Abstract: Any closed compact 3 manifold admits a Heegaard splitting, which splits the 3 manifold into two handlebodies. In this talk, we will use bagels to illustrate the idea of Heegaard splitting. More specifically, we will use 2 bagels to construct 3 sphere and finite many bagels to construct any 3 manifold. Besides, bagels will be provided during the talk.
