Chapter 40: In Which Our Chemist’s Brain Goes Wonktastic

was talking to my mom about how white people ignore the contributions of poc to academia and I found myself saying the words "I bet those idiots think Louis Pasteur was the first to discover germ theory"

which admittedly sounded pretentious as fuck but I'm just so angry that so few people know about the academic advancements during the golden age of Islam.

Islamic doctors were washing their hands and equipment when Europeans were still shoving dirty ass hands into bullet wounds. ancient Indians were describing tiny organisms worsening illness that could travel from person to person before Greece and Rome even started theorizing that some illnesses could be transmitted

also, not related to germ theory, but during the golden age of Islam, they developed an early version of surgery on the cornea. as in the fucking eye. and they were successful

and what have white people contributed exactly?

please go research the golden age of Islamic academia. so many of us wouldn't be alive today if not for their discoveries

people ask sometimes how I can be proud to be Muslim. this is just one of many reasons

some sources to get you started:

but keep in mind, it wasn't just science and medicine! we contributed to literature and philosophy and mathematics and political theory and more!

maybe show us some damn respect

I'd like to give a few examples.

🧪The man known as the father of chemistry (or alchemy, our teacher said both are used for him), Jabir ibn Hayyan. He wrote a book named Kitab al-Kimya, "kimya" means chemistry, and the word chemistry originated from that as well. He invented aqua regia, he had the first chemistry lab, discovered the methods of refining and crystallizing nitric acid, hydrogen chloride and sulfuric acid, and discovered diethyl ether, citric acid, acetic acid and tartaric acid. He developed the "retort" and literally introduced the concept of "base" to chemistry.

📐The father/ founder of algebra, Al-Khwarizmi. He wrote a book called Al-Jabr and the word "algebra" comes from "jabr". He presented the first systematic solution of linear and quadratic equations. One of his achievements in algebra was his demonstration of how to solve quadratic equations by completing the square, for which he provided geometric justifications. He introduced the methods of "reduction" and "balancing". The word "algorithm" literally comes from his name. He also produced the first table of tangents.

📐Biruni, who proposed that the radius be accepted as a unit in trigonometric functions and added secant, cosecant and cotangent functions to it. He made many contributions to astronomy that are too detailed for me to write here because this is long enough already, but for medicine, he managed to make a woman give birth by C section. He wrote Kitabu's Saydane which describes the benefits of around 3000 plants and how they are used.

🩺The father of early polymeric medicine, Ibn Sina. His books, The Law of Medicine and The Book of Healing were taught as the basic works in medical science in various European universities until the mid-17th century. He discovered that the eye was made up of six sections and that the retina was important for vision, performed cataract surgery. He performed kidney surgery, diagnosed diabetes by analyzing urine, identified tumors, and worked on diseases such as facial paralysis, ulcers, and jaundice. He used "anesthesia" in surgeries, invented instruments such as forceps and scalpels to remove catheters and tumors. He was the first physician in history to mention the existence of microbes, at a time when there was no microscope. He made contributions to so many fields: astronomy, physics, chemistry, psychology (he suggested treating patients with music).

🩺Al-Zahrawi wrote Kitab al-Tasrif, a thirty-volume encyclopedia of medical practices. The surgery chapter of this work became the standard textbook in Europe for the next five hundred years. He pioneered the use of catgut for internal stitches, and his surgical instruments are still used today to treat people. He did so much work in surgery that I can't write them all here. The first clinical description of an operative procedure for hydrocephalus was given by him, he clearly described the evacuation of superficial intracranial fluid in hydrocephalic children. He was also the first physician to identify the hereditary nature of haemophilia and describe an abdominal pregnancy, a subtype of ectopic pregnancy that in those days was a fatal affliction, and was first to discover the root cause of paralysis.

✈️Abbas ibn Firnas devised a means of manufacturing colorless glass, invented various planispheres, made corrective lenses, devised an apparatus consisting of a chain of objects that could be used to simulate the motions of the planets and stars, designed a water clock, and a prototype for a kind of metronome. He also attempted to FLY, and he did fly a respectable distance but forgot to add a tail to his wings and didn't stick the landing.

Women also became scholars in the Islamic society. An example would be Maryam al-Ijliyya, who was an astronomer and an astrolabe maker, who measured the altitude of celestial bodies with the astrolabes she made. Another example would be Fatima al-Fihri, who founded the oldest university in the world, the University of Qarawiyyin.

Baghdad was the dream place anyone in academia now would want to go, it was a peaceful place of inclusivity and research. So many scholars advanced so many fields of study. Ibn al-Haytham invented camera obscura (and pinhole camera), Ibn al-Nafis was the first to describe the pulmonary circulation of blood, father of robotics Ismail al-Jazari invented the elephant clock and his list of contributions to engineering are so long that I can't write them here...

These are just a few examples, of course. I hope this encourages people to do research on this topic more. I even added some emojis to make this more fun to read.💁🏻‍♀️

Vaccination in the form of inoculation was introduced to the anglosphere and from there into published scientific literature by an enslaved African man named Onesimus in the 1700s.

I wanted to find a source from someone who was a bit politically engaged with the topic, here’s a sort of starter (although they do assume you have heard of Onesimus.)

Luigi Mangione could be getting the death penalty…

This man is innocent, his appearance and build doesn’t match that of the killers, the only “motive” he had was a convenient written confession showing that he supposedly viewed healthcare companies as “parasitic” and too expensive (which does somewhat contradict the actual killers actions) he had said note and the murder weapon conveniently on him while living his ordinary life, the killer held the gun in his right hand while Luigi is left-handed, Luigi and the Killer were potentially seen simultaneously, they wore slightly different coats.

The NYPD KNOW these are different people, they know the evidence is lacking, this isn’t a mistaken identity, it’s framing, they are trying to make themself appear to still be control by catching this man, humiliating him, killing him, when they know full well that the person they are prosecuting ISNT EVEN THE RIGHT GUY! This is an injustice! This is not a fair trial! This is downright tyranny!

They confiscated his bag at the mcdonald's, took it out of everyone's sight, unpacked it and repacked it, and THEN took it down to the station and wow there was a manifesto in there that he was just carrying around in daily life for some reason

Definitely the sort of thing that the Bag Of Monopoly Money Guy would be carrying to McDonald's

The Porn Guy aka The Nice Guy aka The Canadian side of Pornhub aka SFW Pornhub’s REAL NAME is Ryan Creamer. No joke, that is legit his real name.

Also this.

Which led him to this.

Bless this man.

I can appreciate him and the service he’s providing independently of the shitshow that is the platform he’s hosted on.

He remains just as funny and weird on other platforms dw

By the way, the topic he was presenting was

my guardian angel (currently taking the form of trent 'The Nine Inch Nails' reznor to try and get me to listen to him): do we think maybe a vegetable would cause less 'Hurt'?

did you know you can buy bottles of 200mg caffeine pills for like 5$US. did you know the maximum recommended daily dose of caffeine in an adult human is 400mg. did you know you can overdose on caffeine

doyouknowwhatitfeelsliketohavetwogramsofcaffeineinyourbloodstream

I know what it's like to have 7.2 grams of caffeine in my bloodstream!

Short version: BAD. 0/10 do not recommend. Learn from my bad example.

THATS REALLY BAD

To be fair, I was being careful within my knowledge at the time! I calculated the LD50 for my weight and gave myself a 25% safety margin!

Unfortunately, what I didn't know at that time was really dangerous. Again, I cannot recommend strongly enough that you do not follow in my footsteps. I'm lucky I didn't kill or seriously debilitate myself.

The reactions I got chugging from a bottle labeled "POTION OF SPEED" while vibrating like I was trying to clip through the floor were pretty priceless, though.

Sweet mother of fuck

For those who don't know, the LD50 of a chemical is not the safety threshold for a chemical. No that is the predicted threshold, based on human mortality records if available and animal testing if not (and often estimated from animal morbidty not mortality), at which 50% of people will fucking die.

If you come in just below the LD50 for a chemical, and that LD50 is accurate, you are literally flipping a coin on whether you live or die. (Barring medical attention.)

The range at which chemicals cause mortality also tends to be very large. Some people die at a tenth of what kills other people, some people are unusual and can just chug enough of a chemical to murder an entire building. 25% isn't a good safety margin for anything involving chemicals, I wouldn't be happy with a 250% margin. Also just because the coin toss comes up in your favor and you don't die doesn't mean you're going to be okay! Living through a chemical overdose does not mean you are going to be alright afterward!

So holy fuck I'm glad you made it @wetwareproblem, but also goddamn. You really flipped the death coin and lived, huh?

What @crazy-pages said.

This is on-brand for @wetwareproblem, and somehow I’m both shocked and not at all surprised.

the other shitty thing about being a trans woman is seeing stuff explicitly for “girls gays and theys” or queer women and not knowing if ur actually included, begrudgingly included, or not supposed to be there at all 🤪

“Why are trans women so insular” probably because the queer community spaces that other trans/gay ppl have access to are not reliable for us! Weird how that works!

Well, fuck. Addressing stuff to “girls, gays, and theys” is pithy but we need a better, explicitly trans-inclusive … thing. Intro. Form of address.

A billionaire who accuses his adversaries of being paid shills, while simultaneously offering people $1,000 to cast ballots for his preferred candidate, is telling you everything you need to know about how popular he thinks his own views are, and how many people would support them without bribes.

reblog to give your headache to elon musk instead

I’d just like to point out the growth in this post has mostly coincided with elon’s public spiral downward and I’d like to think we’re all a small part of that

bro can’t think because he’s just got a rager of a migraine 24/7

I get massive headaches nearly every day and I can’t think of a better person to wish them on.

Ok....is it normal for cats to kind of swish and "wag" their tails when happy? For Balam the real moving life that means murder. But for Dali he just only seems to do it when he is happy getting pets or excited to see you.

So for cats flicking the tail means excitement. So sometimes that is anxiety or anger, but sometimes it's just okay a thing is happening

Nodding just the tip of the tail is usually a happy, contented, amused thing. Swishing the whole tail around in big dramatic sweeps is agitation, usually irritation getting close to boiling over.

But sometimes they’ll practically vibrate their tails in an upright posture with a slight crook near the end, the same posture they use in greeting but with a rapid shake, which is basically pretending to pee-mark something. And that’s usually a very happy thing. Mine backs toward any cabinets or ovens I open and does it because she’s hoping that whatever I am making is something she can share and at minimum the human is going to be doing something multisensory and exciting for a while instead of Staring At Rectangles.

This one is definitely moving the whole thing dramatically from side to side when there is big excitement like saying hi to us after a few hours, or drinking the blessed MILK (the most glorious substance, better than even tuna).

More lazy but still pretty big while laying on his side and purring loudly while getting head rubs.

But also while seemingly playfully deciding to hunt the puppy and give it some light baps on the butt.

We are confused.

Edit: I just adhd read this and then read it again. Your cat PRETENDS to scent mark things out of joy??

One of my cats vibrates his tail when he’s happy/excited, along with doing happy stompies with his back feet. Often it’s when he’s excited for food but he does it other times, too.

He also has a swish swish waggle tail motion he does - and that I’ve seen in a previous cat as well - when he wants attention and we are just starting to notice him but before he gets the attention. Frequently it waggles back and forth in wide swishes when I’m talking to him as I’m coming over to pet him.

When he’s focused on something, for example the pigeons that like to hang out on our porch, his tail doesn’t even move. Not a twitch. And when he’s wrestling his sister to tell her to knock it off his tail just sort of fwaps on the ground repeatedly.

I hope this helps clear up the confusion. If not, I hope it was at least enjoyable to read about my cat. :)
