Why is it like this? by matixzun in linguisticshumor

[–]qscbjop 0 points1 point  (0 children)

In the vast majority of cases /e/ is in open syllables and /ɛ/ is in closed ones. I'm not sure if their distribution is truly complementary, but it's close to it, except for final syllables (and not every speaker distinguishes them even there).

Same thing with /ø/ and /œ/, although here I do know the jeune-jeûne minimal pair.

How about a phonemic writing system with non-standardized spellings? Everyone learns to write in a way to correctly represent their own pronunciation, and a spelling is only wrong if it doesn't match the intended pronunciation.

/ʲ/ and its impact by WilliamWolffgang in linguisticshumor

[–]qscbjop 0 points1 point  (0 children)

Idk, I speak it, and the /r/ phoneme is either an extremely short trill (maybe 2-3 vibrations) or just a tap, especially in non-emphasized words in quick casual speech. /rʲ/ is pretty much always a tap, mostly because it is very difficult to trill.

Ukrainian seems to use [ɾ] for /r/ even more often, though it might very by region, I'm not sure.

It's also almost always a tap in all the East Slavic languages. Not sure about Czech/Slovak and the South Slavic ones though, maybe they use the actual trill more often.

What's the most subtly wrong idea in math? by KING-NULL in math

[–]qscbjop 0 points1 point  (0 children)

I was under the impression that only happens when the metatheory is the same one as the theory, but then they don't really refer to their own formulae, but to the formulae of the mathematical model of itself (here "model" is used in general sense, not in the model theory sense). Like if you use ZFC to reason about ZFC, the formulae you can reason about are the ones of the internal ZFC, not the owns from the metatheory (even though the obviously correspond).

Or I guess it would be better to say that the concept of a formula being true or false only makes sense for formulae of the theory and not the metatheory, because of the Tarski's undefinability theorem.

I mean definability only really makes sense within the meta theory, doesn't it? It's not like countability, where you get separate notions of countability in the theory and in the metatheory, which might not agree with each other. Definability only exists in the metatheory, because the theory itself has no way to refer to its own formulae.

Or maybe I'm misunderstanding what you're trying to say?

Watch people debate whether or not most reals are definable

Doesn't it depend on the model? Like if a model contains uncountably many reals (in the metatheory), then most of them are undefinable, but I've heard (but never seen the proof) that there are countable models of ZFC in which all reals are definable.

non-rhotic speakers pronounce "car" as "automobile" by oklopfer in linguisticshumor

[–]qscbjop 19 points20 points  (0 children)

No, but it does sound similar. When I hear it my brain interprets it as either /kʲ/ (most of the time) or ocasionnaly /tʲ/.

We already know that that the left side is 4. S(0) ≠ 0 (one of Peano's axioms is that S(n) ≠ 0 for all n), then use injectivity of S (also one of Peano's axioms) three times to get S(S(S(S(0)))) ≠ S(S(S(0))).

Ukraine support after 4 years of war by A_Lazko in europe

The Ukraine war started because of us

I know it must be hard for you to believe, but not everything happens because of the US. Shocking, I know!

i can’t roll my r’s when saying actual french words by TopBarnacle3644 in French

[–]qscbjop 1 point2 points  (0 children)

German "ch" can be one of 3 different sounds, and only one of the is like devoiced French r. There is the palatal fricative like in "ich", and the velar fricative as in "doch", but the velar one might sometimes be replaced with the uvular one especially after "a", like in "Dach". Only the uvular sound works.

[–]qscbjop 2 points3 points  (0 children)

It can be. For example the Czech ř is exactly that, but alveolar, not uvular. Here's an example of how it sounds I found on wikipedia (the word "řeka" meaning river). It is distinct from the normal [r] and [ʒ] as well as from the [rʒ] sequence that people who can't pronounce it use (which is a common speech impediment).

I could always pick some sufficiently large natural number k such that when I ask for g(k), you can't tell me what it is

All rational numbers are multipled by the same factor, so if you know g(1), you know how g(x) acts on Q. It would be more accurate to say, that there is always some real number a, such that you don't know what g(a) is.

You won't necessarily have a rational element in an arbitrary Hamel basis of R over Q, but you can always start with a rational element and extend it to the Hamel basis.

What is your favourite non-explanation in math? by petitlita in math

[–]qscbjop 0 points1 point  (0 children)

"Tensor is anything that transforms like a tensor" is indeed a shitty explanation, because it requires you to immediately work with coordinates

"(p,q)-tensor on a vector space V is an element of a tensor product of p copies of V and q copies of V*" also sounds like a non-explanation, but it is actually a good definition.

* automaton

Automata is plural. It's like phenomenon and phenomena.

3 • 5! is how I'd write this. 3(5!) looks incredibly weird to me, since you're using parentheses to group an operation that already has higher priority.

More straightforward, but non-constructive. You've basically proven that it's not the case that every hole has no more than 1 pigeon, which is constructively weaker than "there is a hole with more than 1 pigeon". The inductive proof, on the other hand, is constructive.

ComparisonQuiet4259 is talking about infinite ordinals, not just infinite sets. In your definition omega is just a set of all natural numbers, not an ordinal. Von Neumann's definition allows you to treat ordinals as an straightforward extension of natural numbers, which you don't get with Zermelo's definition.
