What is the topology of a shirt?
You would say that a normal shirt has four holes, two for the arms, one for the neck, and one for the torso. But if you had a very elastic shirt, you would be able to stretch it such that the torso hole becomes the edge, which makes it a sheet with three holes.
How many holes does a shirt have topology?
As a normal T-shirt, we know it has 4 holes, 2 for the arms, one for the head, and one at the waist.
What are the properties of T-shirts?
A T-shirt, or tee shirt, is a style of fabric shirt named after the T shape of its body and sleeves. Traditionally, it has short sleeves and a round neckline, known as a crew neck, which lacks a collar. T-shirts are generally made of a stretchy, light, and inexpensive fabric and are easy to clean.

How many holes does a pair of pants have?
three holes
Pants as topological surfaces A pair of pants is any surface that is homeomorphic to a sphere with three holes, which formally is the result of removing from the sphere three open disks with pairwise disjoint closures. Thus a pair of pants is a compact surface of genus zero with three boundary components.
Does a straw have 2 or 1 holes?
So, according to Riemann, because a straw can be cut only once — from end to end — it has exactly one hole. If the surface does not have a boundary, like a torus, the first cut must begin and end at the same point. A straw can be cut once without disconnecting it, and a hollow torus can be cut twice.
What is a shirt Homeomorphic to?
So the T-shirt will be homeomorphic to a disk with three holes. In other words, it can viewed as the connected sum of three annuluses.
Are T-shirts capitalized?
Merriam-Webster sees no need to capitalize it: Main Entry: t-shirt. Of course, if it comes at the beginning of a sentence then it should be capitalized: T-shirts and bluejeans lay in stacks on the table.
What makes a quality T-shirt?
What are High Quality T-shirts Made Of? High quality T-shirts start with 100% high quality, pre-shrunk cotton. That means no itchy synthetic fibers, and no shrinking or shape-changing after your T-shirt has gone through the wash.
What are shirts made of?
The majority of T-shirts are made of 100% cotton, polyester, or a cotton/polyester blend.
Does a hole need a bottom?
The O.E.D. files this usage under the second sense of “hole,” defined as “a perforation” and “an aperture passing through anything.” The first sense of “hole” (“a hollow place, cavity, excavation”) seems to imply something with a bottom; its earliest attestation comes from a land grant charter written in 946.
