But a Polo is the mint with a hole..

What if it was as long as a straw?

You'd probably only get one in each pack.

One's a hollow cylinder and the other is a silly Hollander.

Sorry.

I think we need to define hole.

chambers offers multiple choices some of which pierce and others that are closed.

A hollow place
A cavity
An aperture
A gap
A breach
A pit

Topogically, a mug is the same as a donut...

Does your mug leak a lot? (Or only hold a small amount of coffee in an annoyingly off centre location?)

Your wife is right, you are wrong. Doesn't matter what the question was. Accept that and move on.

I am thinking of the straw as a really long washer where the internal diameter is really close to the external, so if it is a washer it has one hole.

This debate drove people nuts last year

People actually gave a shit (and not out of their mouths) ?

Didn't the post say "The Sun"? Not exactly where you'd look for a considered argument and sense of proportion is it?

Holes don't have to go through anything. If I was planting a tree I would dig a hole, that had a bottom and sides. Therefore the straw has two holes that just happen to meet in the middle.

Correct.

Correct.

Incorrect, you have jumped a step in your logic.

You poke a hole through a piece of paper, you don't poke opposing holes.

A through hole is one hole.

A glory hole is one hole.

There's a hole in my bucket.

All singular.

Bravo. And I raise you:

Oscillate it’s tits a lot...

This shit is pretty much my job...I’m patent attorney. We actually end up arguing this type of thing in court. Is a bore different from a hole? Is a pipe different from a tube? Should you have called your pipe a conduit?  It’s a good job I quite like arguing about this type of thing!

I admit it doesn’t sound all that interesting when I put it like that! 😴

Usually it’s a bit higher tech than a straw...medical devices, gene therapy, that sort of thing. But hey, it pays for bikes.

Given that the atomic structure is 99.9999999999996% empty space, then i'd say there are BILLIONS of holes in a drinking straw........

Functional. A bucket shouldn't have a hole in it. Essentially its a sheet (of leather historically) with the edges gathered up.

(Edit there may be stitching holes but i don't think that's really what you meant.)

Two openings, one aperture, no holes.

totally disagree to the mug/doughnut statement though

Topologically a straw is the same as a washer, doughnut or Polo mint. It's just a surface with a single hole in it. As is a mug, but the hole is the handle, not the bit you put the tea in.

No holes but has an aperture? 🤦🏼‍♂️

If a tube has no holes in it then what is a rod with a hole drilled all the way through it?

That would be a tube.

If you took a sheet of steel and rolled it to produce a tube, it's still a tube but it doesn't have a hole in it. It's a question of semantics, perception and fabrication. Is your tube a 3 dimensional solid with a hole formed through the middle or is it essentially a 2d planar object?  Idealy a drinking straw has walls of 0 thickness, so differs from your rod which has a thickness and specifically existed as an ideally 3d object.

Take a sheet of paper with no holes in it, its got 6 sides in practice but idealy only 2 and most people would agree two except soley to be argumentative.

Roll the ends together to create a tube, its still got two* sides and no holes but its a tube, un roll it, no holes. Push down in the middle its still got no holes and is still a planar object.

Push a pencil through the sheet to create a hole - a breach in the otherwise continuous plane within its defined bounds. Its now a tube to all intents and purposes just of 0* depth. Roll it up, end to end and is still a 2d object with a single hole.

* yes in the real world it has thickness but given the whole hole question is a thought exercise hoplefully even stw can concieve that paper "is" a 2d object.

"Opening", "aperture" and "hole" are synonyms. I'd provide a link if the forum software wasn't quite so spectacularly useless.

A cylinder is a 3D shape primary school kids know that. A tube is cylinder with a hole all the way through, even paper ones.

We teach lots of things to kids that are wrong because they're fundamentally easier to grasp and correct enough.

A cylinder is a 3D shape... A tube is cylinder with a hole all the way through.

Some yes, not all.

even paper ones

Feel free to make a paper cylinder from a single sheet of paper without changing the fundamental fact it's a single sheet. Before you do though, draw a triangle on it. Roll it up. Is it still a triangle? After all a triangle is a 2d shape, even primary school kids know that.

A 2D shape needs to be able to lay flat on a level surface a tube doesn't. The material on object is made from does not define the shape.

So a straw has the same number of holes as a cup. And yet liquid only escapes from one end of a cup.

Did you know there's an Urban Dictionary entry for a leaky straw? I wouldn't have know that if this thread hadn't existed.

Question - Has a straw got 2 ends?

The hole in the cup stops before going all the way through.

A paper cup has no holes apparently.

Very true, but a sheet of paper is easy to work with, and can conceivably be used as a plane rather than a 3d object. So yes paper or jelly all the same in practice but as a thought exercise ones easier.

A 2D shape needs to be able to lay flat on a level surface

No, it needs to have no volume.

If a plane of jelly is planar, if i roll it into a tube, its still planar, viewed from its end you'd not see it as it has no physical presence in the 3rd dimension. Its flat.

That would be a square.

You're digging a big hole for yourself.

If that was the body work of your car you'd call it a dent not a hole...

A paper cup has no holes apparently.

Nothing to with it being paper per se.  One of the cones hasn't got a hole in it in conceptual terms its a two planes, inside and outside. One with a flat bottom is 3d as it has 4 planar surfaces. It consists of 2 2d* shapes (or more in most cases) added together.

Edit - if I'm genuinely wrong...

A 2D shape needs to be able to lay flat on a level surface

What is the triangle i suggested you draw on a sheet then roll up once you've rolled it? I completely accept that in orded to actually exist in a way we can perceive as a physical object a straw has to have wall thickness so isn't a theoretical planar construct but as i say it's a thought exercise.

A real straw has a single hole if that's the word you want to use.

I've never managed to get much tea in a dent.

Thirty spokes are joined together in a wheel,
but it is the center hole
that allows the wheel to function.

We mold clay into a pot,
but it is the emptiness inside
that makes the vessel useful.

We fashion wood for a house,
but it is the emptiness inside
that makes it livable.

We work with the substantial,
but the emptiness is what we use.
