The mridangam is a percussion instrument originating from the Indian subcontinent. It is the primary rhythmic accompaniment in a Carnatic music ensemble. In Dhrupad, a modified version, the pakhawaj, is the primary percussion instrument. A related instrument is the Kendang, played in Maritime Southeast Asia. Its a complex instrument to tune and involves a lot of mathematics to construct korvais.
During a percussion ensemble, the mridangam is often accompanied by the ghatam, the kanjira, and the morsing.

@tchrist Yes, probably. I'm just trying to keep a psycho diary, but in patches; I don't have the stamina to keep it day-in, day-out; for that, one probably needs to gamify the process, or attach a paper table on the wall to motivate oneself to produce at least a couple thousand characters of daily psych diarization
Methylfolate helped vastly. Sadly, the most recent study of 29 depressed patients failed to replicate previous findings of reduced methylfolate in the CSF in treatment-resistant depression. So my response to methylfolate might be a placebo reaction.

A friend of mine finally after like thirty years of suffering and wrong diagnoses got a diagnosis of glycogen storage disease type III(a), and is responding better to treatment than he's ever responded to all their previous attempts like for a tentative McArdle disease diagnosis. These rare diseases are hard to figure out.
It also took them a stupidly long time to correctly diagnosis his wife's lupus.
But that is "easy" in comparison, despite House M.D. :)
@tchrist I read a story about a woman who spent 20 years in psychiatric care, until her friends bunched up together, composed her full medical history and after a bit of sleuthing found out that she had a form of lupus
It seems to me that a key broken thing in healthcare, especially affecting the plight of psychiatric patients, is a lack of any kind of coherent medical history recording.
I've seen how psychiatrists take medical history and how they record it, and it's laughable.
Another friend they decided must have Munchausen syndrome by proxy because of how hard she sought a solution to her young son's agonies. It took them three years to find a doctor to make the call of juvenile rheumatoid arthritis. The kid is doing much much better now on Humira. But she is still angry forever at the medical establishment who had written her off as a quack just inventing her son's agony.
@CowperKettle I did read that.
All these crazy cocktails they pump into psych patients, and others.

Because all these etiologies intermingle. Mitochondrial defects can make you depressed through lack of energy, inability to exercise etc.
I noticed that people often use "gold" and "diamond" in lower case. Yet as far as I see it these are all "proper names" of an abstract idea and really ought to be capitalized. Am I in the wrong here?

I'm really not sure why someone voted to move this to ELL, given that the asker describes themself as "also a by product of the American education system." Do people just read someone's name and assume they're an NNS?
Indeed, I suspect this is the sort of question that a native speaker would be more likely to ask; it's not a question asking whether to capitalize these words--something a non-native speaker might want to know--it's asking why we don't.

A "curate's egg" is something described as partly bad and partly good. In its original usage, it referred to something that is obviously and entirely bad, but is described out of politeness as nonetheless having good features that redeem it. This meaning has been largely supplanted by its less ironic modern usage, which refers to something that is in fact an indeterminate mix of good and bad, possibly with a preponderance of bad qualities.

The expression is pre-dated by an anecdote in Our Bishops and Deans by the Reverend F. Arnold, referenced in an issue of The Academy: A Weekly...

Can you give an example of what you mean? Do you mean something like a function that given some input produces the set of all even integers as its result?
Especially in formal works, you'll sometimes see certain symbols used for particular sets. Some of the more common ones related to number theory include:
ℤ = the set of integers ℚ = the set of rational numbers ℝ = the set of real numbers ℂ = the set of complex numbers
So one might for example say that some function 𝑦 = 𝑓(𝑥) maps a value 𝑥 from ℤ into a value 𝑦 from ℚ. I’ll spare you the formal notation for that.
But those are values IN each of those sets. They are not the sets themselves.
@tchrist So, in relation to his possible worlds analysis of natural language conditionals (e.g. 1975 Indicative Conditionals) Robert Stalnaker posited a function which takes an antecedent proposition and a conversational background as inputs and yields a possible world as its value.
The conditional is true if the consequent proposition is true at that world. I wish to discuss an alternative conditional where the value is a set of worlds at each of which the consequent proposition must be true. Does that sound feasible (in terms of the logic)? Or does the 'set as value' kibosh it?
No, it sounds feasible. He's simply describing the domain.
The world is the range.
> The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.
Any y = f(x) function can be said to "operate" on a set of inputs to produce a set of outputs. Both x and y are actually sets, in some sense. But for doing concrete/discrete operations you need actual scalar values to plug in. The formal language describes sets for the range and domain, and these are not scalar values; they may be finite in cardinality or they may be infinite, and if infinite they may not all be of the same cardinality.
They may not be defined on all possible inputs, either. So for example the integer division y = div(x1, x2) operates on two integers and produces a rational. But the second integer is not all of ℤ; it has the value 0 removed from its set.
Because dividing by 0 is not a defined operation.
I'm talking of course of "normal" arithmetic using the sets commonly understood by people who haven't taken theoretical maths at the university level.
@Araucaria-Him In modern mathematics, everything is a set. So, in some sense, all functions have sets as their outputs (and inputs). Indeed, a function, itself, is "just" a set.
In the area I work in (fractal geometry), one of the tools used to describe certain kinds of fractal objects is an "iterated function system" (IFS). In order to prove that an IFS produces a unique fractal, one usually uses the Banach fixed point theorem, which says, essentially, if a function moves things closer together, then that function has a fixed point.
An IFS is then regarded as a function acting on the collection of compact subsets of some space, and which brings things "closer together" in the Hausdorff metric.
So there is a relatively concrete example of a function taking sets as both input and output.
@Araucaria-Him So: I double majored in philosophy and did a reasonable amount of work on formal modal logic. I highly recommend Ted Sider's Logic for Philosophy if you haven't read it already.
There's also been a lot of work in analytic philosophy around trying to create formal accounts of counterfactual conditionals. This is an extremely hard and largely unsolved problem.
Essentially, the issue is that you don't just need a set of possible worlds; you need a notion of nearness between them. For instance: "If the glass had broken, the sky would be green" is false. Why? Certainly there's a set of possible worlds where the glass broke and that includes (on most accounts of modal logic) one where the sky is green.
The answer is that the "nearer" possible world to our own is one where the glass broke but the sky is still blue, and we only consider "nearer" possible worlds when evaluating counterfactuals.
But this leads to a number of odd cases where the truth values of propositions aren't so clear. For instance, suppose Bob and Steve are identical twins with brown eyes. Now consider these two statements:
1. If Bob had green eyes, Steve would have green eyes. 2. If Bob had green eyes, Bob and Steve wouldn't be identical twins.
Are (1) and (2) both true? Neither? Why?
Anyway, I'm sorry if this is an area you're already really familiar with and I'm just reexplaining what you already know.
But modern analytic philosophy has thus far largely failed to come up with a plausible, widely accepted account of natural language counterfactual conditional statements. Things are a bit better with non-counterfactuals (e.g. now that relevance logic has been formalized) but the "paradoxes of material implication" have now become the "paradoxes of relevant implication."
@alphabet Yes, but the Uniqueness Assumption, the Limit Assumption and the idea that a subjunctive conditional 'If p, q' is true at world w iff either p is not entertainable at w or there is some world where p & q is true which is more similar to w than any world where p & -q is true are demonstrably wrong. Or rather, the first two are irrelevant to counterfactuals and the last is just wrong
@Araucaria-Him Exactly! And nobody's figured out how to fix those problems. Even if you solve the "nearness" issue you're still left with a bunch of other problems.
I think any successful account of counterfactuals will probably need some notion of similarity (perhaps I could be persuaded otherwise) but even that wouldn't solve the issue.
And again, I'm probably explaining stuff you already know.
@alphabet Yes, there are five or six good theories of subjunctives, all of which are ingenious in their own way, and none of which nail it. And, in fact, for each of those theories you'll get people saying that it's the leading or most widely accepted theory. Which shows how bad things are. And the same's true for 'indicatives'
@Araucaria-Him Exactly. I think the situation for indicatives is better because there are at least non-insane formal approaches for capturing most of the major issues; much of the debate is just around which best conforms to natural language. With subjunctives, even the supposed "good" accounts are batshit crazy as far as formal logic is concerned.
@alphabet Well, you need at least a notion of similarity because the worlds in which q is meant to hold should not be more different from the actual world than justified by the conversational background and the antecedent (and other pragmatic factors allow)
@alphabet The situation for indicatives is just as bad! Which theory of indicatives do you find least embarrassing, out of interest?
@alphabet You fancy proofreading (not for typos etc, for intelligibility, consistency and errors of fact, and possibly for fun) a paper that I have to submit soon and haven't finished writing yet? It's about the fact that subjunctive/remote conditionals don't convey improbability or counterfactuality or negative espistemic stance? It's a chapter for a book. Got a very small amount of philosophy in it.
@alphabet It's pretty difficult not to get ordering semantics entwined with similarity one way or another.
@Araucaria-Him I think that various modal and relevance-based accounts of material implication have managed to capture most of the unusual features of indicative conditionals. I wouldn't say it's a solved problem by any means, but there are multiple eminently plausible proposals.
@alphabet History, as we understand it, is "just" a particular path through the state-space of the universe. There are "obvious" metrics on that space for measuring "closeness". I don't see what the big deal is. :P
For subjunctive conditionals, I'm not even sure that the ordinary possible-worlds approach to modal logic is capable of giving a decent account. Or at least I haven't seen one.
@alphabet I'm surprised you think so. From my point of view it looks like this: If you have material implication you have to explain why nobody believes a conditional like "If I'm over eight feet tall, I'm under six feet tall" and so forth (lots of people explaining why people don't say that type of thing, but that's irrelevant), and if If P, Q can be false when P is false then you can't infer If P, Q from Not P or Q or make lots of other simple inferencs we know to be reliable.
Where the latter would be what you got on Stalnaker or a relevance conditional or whatever.
Which leave you with no truth value, when all around us the evidence is that natural language conditionals have truth values for humans.
@alphabet Thanks Mr Raccoon, re reading it over. I'll definitely get back to you (but if you change your mind, no worries!)
@Araucaria-Him I think that the answer is something like: When evaluating the truth value of a conditional, people take into account the existence or nonexistence of a causal connection, and whether the claim is true in nearby possible worlds. The exact sort of connection required will depend on various contextual or pragmatic factors.
In other words: you need to build on the notion of truth-functional material implication in various complicated ways to capture the semantics of natural language conditionals, but it seems at least possible to do so in a reasonably sane manner.
It's worth noting that e.g. there are similar problems with e.g. and, or, but; those clearly bear a relationship to purely truth-functional operators but aren't identical to them.
@alphabet Hmm. I have multitudinous bits of evidence that that's not the case (there's no nearby worlds involved for indicatives). But I'll wait till after my viva before wheeling those out! Actually, you'll read about one of those if you read that paper. There's no doubt that you're no alone/you're in good company with that kind of interpretation (but you do lose all those inferences!)
For instance: is the statement "I went home and took a nap" true if you took the nap before going home? It seems like there's a very general problem with translating between natural language and truth-functional operators.
Likewise, what about the statements "Either 5 + 7 = 12 or birds exist" and "Either 5 + 7 = 12 or birds don't exist"? Are those true, false, neither? If you interpret the word "or" as a purely truth-functional operator you'd have to say "true" but I think most people find that, at the very least, counterintuitive.
The same goes with "if." Of course, you still have those inferences in formal logic, but there's never any straightforward mapping between formal logic and natural language.
Counterfactuals are trickier because there's no truth-functional operator in propositional logic you could even base it on.
But in a conditional of the form "If I weren't right-handed..." you can't just assume "I am not right-handed," since then "I am not right-handed; I am not left-handed; I am either left-handed or right-handed" would be true--but that's logically inconsistent.
@alphabet Well, you have to be very restrictive on what 'p' can refer to. It can't be modal or interrogative or subjunctive, it has to be a statement that can be true or false.
@Mitch Well, no; those three statements have the form "~p and ~q and (p or q)" which in classical formal logic is false.
In this case the fix is fairly obvious: when you assume "I am not right-handed," you also have to jettison at least one of the other two claims. But it's not always that simple.
@Mitch I mean the statements "I am not right-handed; I am not left-handed; I am either left-handed or right-handed."
Which you get if you start with "I am right-handed; I am not left-handed; I am either left-handed or right-handed" and then try to "assume" that "I'm not right-handed" in a counterfactual scenario.
get rid if the handed ness stuff. "-R and -L and (R or L)" is one world. the other world is "R and -L and (R or L)" (identical to the first one except the first conjunct is positive.

If you change the phoneme, you change the word. If you merely change the phonetics without changing the word, it is but an allophone of the same phoneme.

Please don't mention the third formant. The gaskets are too loosely held already.
I feel like we really need to have a meta discussion about what "opinion based" means, tho I don't have time to write such a post. Cf english.stackexchange.com/q/621730/191178
@tchrist The flip side of that benefit is that now 9ths are starting to feel like octaves, especially after a very stretchy passage. Which is a disaster. But I can get used to it.
2) just starting it should be easy... "What does opinion-based mean here?" with a couple recent links to closed and reopened by opinion-based.
3) the problem is not a lack of definition in general, it is -those three guys- (and a few extras) who love to close as opinion-based when they as individuals don't know the answer.
Only if those three guys are actively involved in the meta question -and- convinced that they should stop over-closing stuff will there be any change.

@tchrist wants to mention the third formant so badly now
@tchrist awesome sentence...is there one for GenAmE? (I think the only real difference is 'aught' is weird for Americans, and 'art' is rhotic so should be 'cot' or 'father')
@Mitch That one IS for American English!! The writer needed to choose words in a particular sequence. The low back vowels of ART and FATHER are identical. Just because you pronounce the R does not mean that the vowel before it is rhotacized. It is not — at least not phonemically. It can be pronounced as two phonemes in sequence, unlike the NURSE vowel which is itself r-colored and inseparable. So irk, erg, urn have 2 phonemes each but art, orc, hours, eared have 3.
As for aught, I have nought new to say to you that I have never said before: read a book or two antedating your birth would you come to understand written, literary English — and tarry at a preschool playground would you not.
@Laurel If I catch it in time, I comment to the effect "Why is this considered opinion based? If this is opinion based then -all- questions on SE are opinion based. Just because you don't know the answer doesn't mean there isn't an objective to be had." I'm sure there are nicer ways to say it than that.
IMO, a question should be closed as "opinion-based" only if it's effectively unanswerable because it would be impossible to find sources or other evidence to support an answer, or if there's no way to judge if an answer is correct.
Ultimately, the real issue is that such answering such questions provides little actual benefit to the asker, except as a sort of badly conducted opinion poll.
That's 1) not what opinion-based means, 2) and maybe it would be a new close reason 'unknowable/in principle unsupportable', but that would be a bad close reason... many of the 'closed as opinion based' -are- answerable by someone who a) is knowledgable or b) has the right data tools.
@alphabet that may be the case sometimes, but the usual 'closed as opinion-based but are not opinion based' are often of the style 'here is a phenomenon that I just noticed I am wondering about' which seem unanswerable if you haven't done the research, but if you have it's answerable.
@Mitch Ultimately, I think all our close reasons basically boil down to "Our community can't provide you with an answer that will be particularly helpful to you or others." The different close reasons are just different reasons why we might not be able to do so.
@Mitch I mean that actually opinion-based ones are like that. But there are plenty of purportedly opinion-based ones that are.
Here's one that, as I recall, was the subject of a heated debate as to whether or not it was opinion-based, and went through a couple close-reopen cycles:
Does one pee-pee with his wee-wee, or does he wee-wee with his pee-pee? Is one phrasing more typical than the other?
That is to say: How is pee-pee used more commonly- as "to urinate" or as "penis"? And vice-versa for wee-wee. I'm curious if there are widespread or regional customs.
Both are info...
Ultimately my answer proved the question was to some degree answerable in an objective way. But even if I hadn't found a study, it still wouldn't've been opinion based IMO.
Incidentally: I tried conducting a follow up study by confronting kindergartners and asking them what they call their genitals. Apparently now I'm "banned from the public playground." (Just kidding. I was, of course, already banned.)
A legitimate answer to that question would say there might be variation, and say it is currently not known for sure (data needs to be gathered). Or maybe some one -does- know the variation? But anyway, it shouldn't closed for that reason.
@Mitch I'd argue it's better to leave a question unanswered than to say "nobody knows." If the "nobody knows" answer gets accepted, then someone who does know might come along later and be unable to get the accepted answer changed.
@XanderHenderson Agreed; "nobody knows, and here are the citations which justify this" is fine. But it's usually hard to find good citations for a claim like "nobody knows."
The issue is that, once an answer is accepted, it can't be deleted, even by the person who wrote the answer. You need the asker to un-mark it first.
I've run into this before, where I wrote an answer that got accepted, then later realized it contained a rather embarrassing factual error.
Ah. I didn't know that. Regardless it would make it hard to get rid of an inaccurate "nobody knows" answer.
Incidentally, might want to get rid of the awful answer on that question I linked; the comments on it explain why it's embarrassingly wrong and the answer right below it is correct.
Then please vote to get rid of the one on that question, because it has -30 points and is incredibly dumb (my apologies to its author).
The asker is, incidentally, a notorious troll--apparently his deleted posts, which I can't get a list of directly, are even "better"--which may be why he decided to accept that particular answer.
@alphabet that's not how SE works. Of course you can get a new answer become the accepted answer. It's not as easy as it should be (because people aren't continuously monitoring their questions), but it -is- possible. The SE designers made sure that things could be changed (but not on a whim)
@Robusto Yeah, but that saying is only attested decades after the phrase "take the biscuit" became common and the other answers provide actual evidence.
