Does a straight straw have one or two holes?

Does a straight straw have one or two holes?

one obviously
/thread

How?

it's basically a coin with a hole. stretching it doesn't change a thing.

Rings have one hole, straws have two holes.

how do you introduce the other hole just by stretching the ring retardinio?

cover one end and it's a sock
sock is no different than a sheet

A straw is just a hollow cylinder without a top and bottom

what's a ring then?

A straw has one hole, but two openings.

the same thing

chemically it's full if small pores, so millions of them

These sock arguments are too powerful. We need to ban them.

Just calculate the homology of the straw.

[eqn]\widetilde H_n(\text{straw}) = \begin{cases}
\mathbb{Z} & n =1 \\
0 & n \neq 1
\end{cases}[/eqn]
therefore one hole in dimension 1 and that's it

If you drill through something, are you drilling one hole or two

How thick is the wall of the straw?

doesn't matter, it still deformation retracts onto the circle

There are two entrances to the interior, hence it has two holes.

What about a gay straw?

It depends on whether you consider a "hole" to be a boundary component, or a generator of H1.

Also go back to R-ddit.

based reddit spy

gay straws clearly have two holes.

If a hollow cylinder is longer than its diameter it has 2 holes. If it's shorter it has one.


Simple

Prove it.
