How Many Holes Does a Human Have? - Summary

Summary

The speaker in the recording is discussing the concept of holes in the human body. He first introduces the idea that the human body can be compared to a doughnut, with the mouth and anus being the "holes". He then mentions that the body is not a solid object but a collection of atoms and molecules.

The speaker introduces the concept of a "through-hole", which is a hole that allows passage from one side to the other. He mentions that the mouth and anus, as well as the esophagus, are examples of through-holes. He also introduces the idea of a "blind hole", which is an opening that cannot be traversed. He mentions that the nostrils, ears, hair follicles, birth canals, and sinuses are examples of blind holes.

The speaker then discusses the concept of a "hole", explaining that it is a colloquial term that refers to a host of disparate things. He explains that a hole might not even exist, depending on the context. He uses examples of different objects, such as a doughnut and a coffee cup, to illustrate this point.

He then introduces the concept of a "through-hole doughnut", which is a doughnut that has a hole through it. He explains that a doughnut has one through-hole, while a coffee cup has two. He then discusses the concept of homeomorphism, a mathematical concept that describes the properties that persist when an object is continuously deformed. He explains that a coffee cup and a doughnut are homeomorphic, meaning they have the same number of through-holes.

The speaker then discusses the concept of a "topological hole", which is a hole that cannot be erased through a homeomorphism. He explains that unlike a blind hole, what qualifies as a topological hole is not a matter of opinion.

The speaker then discusses the concept of a "seven-hole doughnut", explaining that the human body can be molded and stretched into this shape. He explains that the human body has seven through-holes and eight external orifices.

He then discusses the concept of an "accessory ostium", which is an additional hole connecting a sinus to the nasal cavity. He explains that these are topological holes and need to be added to the body's total.

In conclusion, the speaker explains that the human body has millions of blind holes and seven through-holes. He suggests that the only way to know for sure is to explore one's own body.
