I’m a career physicist, and I honestly have no idea what a state of matter is anymore.
Can I offer you a nice smectic B3 liquid crystal in this trying time?
yeah i have a bachelor’s in chemistry and I remember a professor earnestly saying the phrase “metallic phase nitrogen” and I think I went home and stared at the ceiling for an hour
though the meme is cool, gender isn’t particularly a biology (or ‘advance biology’) thing. biology deals with sexes, their expressions and functionalities. gender is more of a personal and social concept but often related to sex characteristics (cis).
and yes, advanced biology tells sex determination isn’t as easy as XX or XY or even looking at genitals like a creep.
and oh, for giggles consider fungi :)
Slime mold(which is not a mold or fungi) looks around nervously in it’s 13 different sexes.
I would say gender is probably centered about around psychology, ranges mostly from sociology to biology, with a just little bit going into chemistry
maybe like
Adding to this: XX and XY works for mammals, but not for other vertebrates (fish, birds, reptiles, amphibians). Birds and reptiles have Z and W chromosomes, and unlike in mammals where females are homozygotes, males in these groups are homozygotes. Some reptiles have temperature dependent sex determination, where ambient temperature above some value will produce males or females (depends on species). Some reptiles are composed entirely of females.
Some fish will straight up change sexes depending on age and male-female ratio in a social group.
In other groups it’s not even different chromosomes but simply copy number of specific genes.
Plants can do all sorts of whacky things like produce seeds and pollen in the same individual.
Fungi are an entirely different cluster fuck because they have mating types which are not simple binaries.
Eukaryotic sex determination isn’t a binary and it isn’t even a nicely categorizable spectrum. It’s a grab-bag of whatever doesn’t perma-fuck your genome.
Source: me, I’m a biologist. Though admittedly I work on animals so my understanding of fungi and plant stuff is fuzzy at best.
What kind of fungi should I consider for the maximum giggles?
Psychology is technically a branch of advanced biology

So true and it’s a great to remind them of that sort of thing.
You know, you’d think all of the people who say it’s purely down to genetics would be natural allies with, you know, molecular biologists (applied genetics). They’d be all like “it’s a Y chromosome or nothing” and the biologists would be all like “yeah chromosomes!” because we fucking love chromosomes but no. In fact, it’s noticeably absent when you start to think about it.
I wonder why that might be?
The short answer is “because it’s infinitely more complicated than that.”
Just because you carry the genetic code for anything at all, it doesn’t mean you’ll express it. The default setting for our DNA is off. So, if something isn’t telling it to transcribe, it won’t do it. A whole load of reasons could cause that, even before we get to mutations and partial expression or chimeras etc.
Anyway, what i mean is yeah, this meme!
Edit: also, don’t beleive the AI. Early fetuses are female, until the Y is activated. You could have an inactivated Y and the fetus could be a woman capable of having children. The default setting is female, not intersex. It could be either but unless a specific event happens, it will always be female. It’s a subtle but important difference. This means that all fetuses are female and then turn into a male.
When Newton worked out the laws of motion, he figured they had to be correct because they were so simple and elegant.
He had no idea that relativity was going to come in and fuck his shit up.
And then there was quantum.
Do you have any idea how fast you were going?
No officer, but I can tell you exactly where I am!
Which is also simple and elegant
And then string theory. Which . . .
TBF the laws of motion are still correct.
it’s not that they are “correct”, it’s that they are a close enough approximation to work well enough at the scale they’re used. it’s not like the universe runs on math.
I mean relativity is elegant enough in its own right; it’s just Newton’s laws plus the constancy of the speed of light and the equivalence principle. These two additions are enough to make everything an order of magnitude more fucked up, but that’s math’s fault, not relativity.
now do quantum
He did also notice that the planets didn’t move quite exactly as he predicted and said “well, God must keep them in place”
A genderino sounds more like something you’d find in particle physics than biology anyway
finally, we found what genderfluid is made from
Considering the names of the types of quarks, I recommend renaming them genderinos.
Physicists are freaky, like who was out there going and asking quarks what is their power dynamic in sex?
“I’m a charm in the streets, and a strange in the sheets.”
I’m down for a strap on, but what is a glue on??
This guy rotates
It also kinda sounds like a Pokémon!
Honestly, people would probably object more to advanced math than advanced biology if they were exposed as much to it. Or basic math. Or elementary math…
I can confirm. My partner does math professionally and sometimes she tells me things about her field that are just plain unnatural. And I’m a pretty open-minded person.
Math is extremely irrational.
Math is not real sometimes. Imaginary, even.
Math even is non-constructible a lot of the time!
i
I mean, aye!
j, k
Wait, now there are 3?
e0…e7
What now mutha fucka?
The problem is those morons haven’t taken any of the advanced classes and probably got D’s in the basic ones.
Always wear your glasses. Sans glasses, I read the Advanced Math panel saying the square root of -1=1, and thought, “that’s doesn’t sound right.”
Sqrt(-1) is still wrong tho. I’m commuting a sin by writting it. Correct expression is i^2=-1
Indeed, usually you would want to avoid a notation of
sqrt(-1)or(-1)^(1/2). You would usee^(1/2 log(-1))instead because mathematicians have already decided on a “natural” way to define the logarithm of complex numbers. The problem here lies with choosing a branch of the logarithm ase^z = xhas infinitely many complex solutionsz. Mathematicians have already decided on a default branch of the logarithm you would usually use. This matters because depending on the branch you choosesqrt(-1)either givesior-i. A square-root is usually defined to only give the positive solution (if it had multiple values it wouldn’t fit the definition of a function anymore) but on the complex plane there isn’t really a “positive” direction. You would have to choose that first to make suresqrtis defined as a function and you do that via the logarithm branch.
So, just writingsqrt(-1)leaves ambiguity as you could either define it to giveior-ibut writinge^(1/2 log(-1))then everyone would just assume you use the default logarithm branch and the solution isi.But (-i)^2=-1 as well. So we still need a convention to distinguish i from -i.
Wolfram tells me
sqrt(-1) = iand it hasn’t lied to me yet.In what meaningful way is
i^2 = -1different fromsqrt(-1) = i?sqrt(-1) = ±i. The negative answer is also valid.
Ah, good point; I’d forgotten that part.
Square root definition does not allow a negative number as an input. Only positives and zero. Although it is possible to expand the definition to negative numbers, complex numbers, matrices… So unless you followed a course where you thoroughly defined your expansion of sqrt, it only applies to real, positives number and zero. Its the thing with math, you have to define what you work with.
In my case, I did prep courses for entrance exam to engineering schools (something like in dead poet society but more modern), using sqrt(-1) somewhere would be an instant 0 mark. Like forgetting a unit in a physics test answer.
Sounds to me like this is exactly what the OP meme is referencing.
Basic math: square root only of positive numbers and 0.
Advanced math: square root of anything you want
So what’s the square root of your mom then?
Damn, hoisted by my own petard.
I’m very sorry you had to go through such stupid school tests, welcome to the real world.
sqrt(x)is just a shorthand forx^(1/2).
Wouldn’t the square root just give plus/minus i? Seems correct enough.
No. The symbol √ signifies the principal square root of a number. Therefore, √x is always positive. The two roots of x, however, are ±√x. If you therefore have y²=x and you want to find y, you mustn’t write y=√x, but rather y=±√x to be formally correct.
They’re the same thing. You just take the square root of both sides to get i = sqrt(-1).
Nah, sqrt(x) is the principal branch (the one with a positive real part) of x^½, and you can do (-1)^½ because it’s just exponentiation.
Simply define it as i = e^(iπ/2) 🤣
