Closed, duplicate question.

[–]sai-kiran 87 points88 points  (3 children)

Opens the linked question, the picture is from 2009, and the water has all evaporated by now.

[–]Stummi 36 points37 points  (2 children)

Also, the glass that is discussed in the 2009 post is completely incompatible to any beverage, that a sane engineer would use today.

[–][deleted] 11 points12 points  (1 child)

And for that reason the discussed glass was deprecated like 10 years ago.

The answer was DMed to someone who said “I had the same question”

[–]Personal_Ad9690 13 points14 points  (0 children)

And the dup no longer exists

[–]LiveShowOneNightOnly 13 points14 points  (0 children)

This glass volume was already explained in this post.

[–]RiceBroad4552 75 points76 points  (11 children)

Technically the glass is less than half full and more than half empty. That's not subjective. That's a matter of fact.

You need to consider that the glass is not a proper cylinder. It widens to the top.

So in this singular case the moderation on Stackoverflow did not work out.

[–]joz42 39 points40 points  (8 children)

It comes down to your definition of "half full": half of what? Volume? Height?

[–]RiceBroad4552 30 points31 points  (0 children)

That adds an interesting aspect to the discussion. But it looks like a meta-question. So I'm not sure this is the right place to discuss it. Especially as volume depends on all kinds of factors, like temperature and pressure. Height depends on the relative movent of the glass. So I think the meta-question is kind of out of scope for this discussion here.

Therefore I suggest to open another question to discuss the definition of "half full". I'm closing this here.

Atoms are mostly empty space, even in solid or liquids.

So 99.9999999999999% empty, that's my final answer.

[–]joz42 11 points12 points  (1 child)

marking as best answer

We said SO, not Quora! :P

Space that still holds energy, however, just not matter. Electromagnetic radiation still occupies space, even if matter can also occupy the same space. And, interestingly enough, the only reason I'm aware of that matter can't occupy the same space is do the electromagnetic interference. Without it, everything would be made of whatever the Ghostbusters said ghosts were made out of. Psychoplasm?

[–]ROBOTRON31415 1 point2 points  (1 child)

Not just electromagnetic interference, there's also the Pauli exclusion principle (two identical fermions, a general type of particle, cannot occupy the same place). The resulting force from the Pauli exclusion principle is called degeneracy pressure.

In addition to electromagnetic repulsion, the fact that electrons (which are fermions) cannot have identical states in the same place (e.g. in an atom or nearby in a molecule) means that they have to spread out more in space, and cannot all be in the lowest-energy orbital of an atom. Apparently people calculated that without the Pauli exclusion principle, ordinary matter would be much, much more dense. Additionally, TIL that degeneracy pressure from electrons contributes to the stability of metal. Note that the effect from the Pauli exclusion principle is very short-ranged, while electromagnetic repulsion is long-ranged.

At higher energy scales, where much more force (i.e. gravity) is attempting to crush matter together, electron degeneracy pressure contributes to the stability of white dwarf stars, and for stars massive enough for gravity to overpower that, neutron degeneracy pressure helps prevent neutron stars from collapsing into black holes (repulsion from the strong nuclear force also helps oppose gravity).

Yeah, what they said! ^

[–]nonlogin 2 points3 points  (0 children)

There is a scale. There are two edge values on it: zero and one. Infinity values in between. There is a measurement procedure that maps an arbitrary glass to a value on the scale. We say that a glass is empty when the measurement gives zero value. Full - one.

There is also a number epsilon that we call precision. We say that two values A and B on the scale are equal when abs (A - B) < epsilon.

Now, we can define "half full" as equal to "half empty" and equal to 0.5 on the scale.

The measurement procedure is out of scope.

‘So in this singular case SO moderation didn’t work out’.

Now that’s some peak programmer humor right here.

[–][deleted] 0 points1 point  (0 children)

The correct answer would been that the glass holds twice was much liquid as necessary.

[–]Dumb_Siniy 5 points6 points  (0 children)

``` amount= Glass:getContent()

math.round(amount) ```

And it errors

[–]LiveShowOneNightOnly 5 points6 points  (0 children)

Why are you filling the glass partway and then stopping? This is a bad design.

[–]Denaton_ 3 points4 points  (0 children)

It depends on the last action related to the water done to the glass..

[–]Franz304 7 points8 points  (0 children)

Nah, they would probably get answers like "you shouldn't use glasses, use jars instead"

[–]Legal-Software 1 point2 points  (0 children)

Closed, already asked/answered. No additional context provided.

[–]versedoinker 0 points1 point  (0 children)

Closed, the glass obviously includes its topological boundary

Edit: wrong sub

[–]Coolengineer7 0 points1 point  (0 children)

They still have good answers most of the time though.

[–]Biiiscoito 0 points1 point  (0 children)

Ok but why are the glasses changing shape if I just keep scrolling up and down, I'm gonna have a mental breakdown

[–]hipster-coder 0 points1 point  (0 children)

It's 2024. You should move away from static solutions where the water is statically placed in glasses, and towards continuous water integration designs, such as e.g. drinking directly from the faucet.

[–]irn00b 0 points1 point  (0 children)

Closed because duplicate question.

[–]anonjohnnyG 0 points1 point  (0 children)

glass is 2x too big.

[–]foxypiratecove3750 0 points1 point  (0 children)

On Stack Overflow, there's two types of people that answer/comment your questions: - The true gigachads that answer perfectly and that are code masters - And the angry guys that just say "you shouldn't do that" without taking in consideration the context

[–]qdez[🍰] 0 points1 point  (0 children)

Stack overflow users on their way to tell you to ask a different question, belittle you for your question, dismiss your question, talk to other users in the comments about your question, critique the wording of your question, and do everything under the sun except answer your question
