@vzn Umm, the thing is the entrance exams test fishes by their ability to climb trees. So I sort of understand Balarka's situation. It's not really his type of maths (although I'm sure he's quite comfortable with it)

@vzn My close family members have schizophrenia (and it's provably inheritable, so I have a sufficiently nontrivial probability of having schizophrenia later in life). Not even joking.

@Blue BaSe probably will not like the multidisciplinary aspect of the tests, not focused on math. but still think the other areas will not likely be hard for him.

@Inflationary_Bubble Whether off-topic is okay or not depends on the room. In this room we're perfectly fine with "off-topic", but there are other chats with different rules

Balarka Sen

@ACuriousMind Ah, good point. Well my issue with "they" is that I am too used to using it in the plural.

It just feels like I am referring to a person indirectly :P

Mithrandir24601

@ACuriousMind oddly, the thing that convinced me that I'd rather get rid of genders over start using another term, is precisely because I view things like 'ze' as the English version of the Germans' neuter gender, which makes me think that in the future, if this keeps up, people are just going to want a fourth gender and the problem's just going to get worse, not better

Anonymous

@Mithrandir24601 People will always find out stuff to get offended about, no matter how hard you try. :P

@BalarkaSen Hah, that's no issue for a German because our polite form of address for a single person is identical to the 3rd person plural

ACuriousMind

7:51 PM

@Mithrandir24601 Well, that's because the neutral 'it' is reserved for things in English, i.e. using it for persons is implicitly dehumanizing.

Mithrandir24601

@ACuriousMind which is why it's not truly a 'third gender' ;)

ACuriousMind

Indeed - the neutral grammatical gender is not supposed to correspond to any human gender!

Balarka Sen

A lot of people who identify themselves as nonbinary actually prefer to be referred as a gender neutral

I think "zhe" and "zher" are gender neutral, technically

It's too confusing

Mithrandir24601

@BalarkaSen I don't even know how I'm supposed to pronounce such words

@Blue As I already told Balarka, the German polite address for a single person is identical to the third person plural, so I don't think "sounding plural" is an argument against using it for single persons ;P

@Mithrandir24601 Yeah, I know that definition. Just my personal issue maybe

Let "them" decide...

Mithrandir24601

supposedly "The word they (with its counterparts them, their, and themselves) as a singular pronoun to refer to a person of unspecified gender has been used since at least the 16th century"

Balarka Sen

7:57 PM

It's not unnatural to you, but it is to at least a proportion of the English speaking world.

Mithrandir24601

all of the above are just more reasons that I'd rather get rid of 'gender' entirely than introduce more genders

Look at Jordan Peterson's argument on why he doesn't want to use it

It's analogous

Q: Umbiguity of $k$-vector in solid state physics

It is known that $k$-vector is defined up to a reciprocal lattice vector. So we can write in one dimensional case $$k'=k+ \frac{n\pi} {a}.$$ But this corresponds to a completely different wavelength and energy! In fact energy is infinite for $n \rightarrow \infty$. Is it normal after all ?

Pinacol coupling reaction

A pinacol coupling reaction is an organic reaction in which a carbon–carbon covalent bond is formed between the carbonyl groups of an aldehyde or a ketone in presence of an electron donor in a free radical process. The reaction product is a vicinal diol. The reaction is named after pinacol (also known as 2,3-dimethyl-2,3-butanediol or tetramethylethylene glycol), which is the product of this reaction when done with acetone as reagent. The reaction is usually a homocoupling but intramolecular cross-coupling reactions are also possible. Pinacol was discovered by Wilhelm Rudolph Fittig in 1859. ...
