How many holes are in a T-shirt?

Imagine a typical t-shirt, brand new, without any damage or decorations attached to it, and pretend that it has a printed-on label (to avoid the technicality of a potential loop created by a hanging tag).

Does opening a sealed can of food add (at least) one hole to that can?

  • Yes
  • No

0 voters

Imagine you opened the can the typical way with a can opener by cutting out the top.

Then, after you emptied the food from the can, imagine that you also cut out the bottom.

Does cutting out the bottom as well put another hole in the can?

  • Yes
  • No

So, this hypothetical can is now just a cylinder of metal open at both ends.

Is the shape of this hypothetical can fundamentally different (besides proportions, scale, and some negligible burrs left from cutting) than the shape of a straw?

  • Yes
  • No

Does this hypothetical can (with the top and bottom cut out) have the same number of holes as a straw?

  • Yes
  • No

Does this change your perspective on the “holes in a straw” question?

A straw has one whole through the whole straw, same size, same place. A can where you cut holes (plural) through the holes are different because your cutting different holes at different times in different places and different sizes.

My reasoning was rather simple. I took a lesson from the other poll (where C was the most chosen option).

Here is the thing: people always choose C. It is a fact of life. I thought most people would know this and therefore vote “D) Option C”. Alas, I was wrong; the lesson: the question does not matter all that much, behavior would stay approximately the same.

For your question there’s a small difference. People do have to make a calculation. So, again, I think “Well, the average is 10, so people will tend to choose 2/3 of 10, so I’ll choose 2/3 * 2/3 * 10”. I disregarded the infinite descent (even though it is the only logical conclusion) because, again, the question does not matter.

Are you familiar with the candy “Pixy Stix”? It’s basically just flavored sugar sold in a paper or plastic tube (that’s been sealed at both ends).

With the plastic tube variety, you typically cut off one end to dump out and eat the sugar. However, you could then also cut off the other end and be left with something shaped just like a straw. Since I cut two different holes at two different times in two different places, does this “Pixy Stix” straw have two holes?

None of this is meant to be a mathematical argument. Topology unambiguously gives a precise answer, which makes the mathematical argument trivial and uninteresting, since it all just boils down to the rigorous mathematical definition of a “hole”.

However, within the realm of natural language and how we commonly use the word and concept of “hole”, we are left to deal with vagueness, ambiguity, and even inconsistencies and contradictions.

EDIT: to reply to something said later

My instructions above clearly suggest eating the sugar before cutting off the second end.

you wasted a pixie stix :cry:
Hmm… If you cut a straw into really thing pieces so it’s like a string would it have 1 or 2 holes?

Interestingly both as a two-dimensional manifold as well as a solid, the answer is topologically 3.

Here’s the topological view: as a solid, the sealed can has a hole (a 3D hole in 4D space, so to say), but when the lid opens but is still attached it loses this hole and becomes a ball. When the lid is detached completely we’re left with two balls.

Should we make a different topic for this?

Black stripes are usually an adaptation. Even black cats often have black stripes (that would tell you that those stripes are indeed stripes, and not base color).

In the case of zebras, there was a close relative (the Quagga) which had mostly horse-like coating with black stripes :woman_shrugging:

So spesifically the shirt question.

It has no holes… Because, as I understand it, it’s made from two seperate prices of material that are sewn together, and the “holes” are made from simply a lack of sewing in those spesific areas. Meaning that, in essence, it’s “holes” aren’t actually holes at all.

Yes, it does have two holes then. But the straw doesn’t, because it never had sealed endings that had to be cut open. I feel the same about the T-shirt question: When I count the openings, there are four, but they are openings, not holes. The T-shirt will have holes later, when there’ll be holes in places that were originally closed.

Like you said, that is of course not a mathematical view.
I wonder how much my view is culturally shaped, or if it is a more of an individual thing.

If your small and walked on your legs, how do you not have legs?

Yes. The holes are different shapes from each other too. Originally it had no holes, then you added one and another. A straw always had a hole going through the middle. This didn’t change. It had 1 hole and stayed that way. The can and the pixy stix started with no holes and someone cut two holes into them.
