Colonial heritage in natural history

Thread 1 - Poinsettia and Monroe's Doctrine
mathchaos.bsky.social Omar Rafael Regalado Fernández @mathchaos.bsky.social · Oct 23
Thread 1 (from 12 September 2022)
This flower is called a Poinsettia in English. September is the best time to discuss the name's connection to colonialism and why I would never call this plant a poinsettia.
Photo of a flower typical from North America known in English as Poinsettia. The actual flowers are small and yellow, but they have large flaming red bracts at the base, followed by leaves that have a combination of red and green colours. The photo is taken from above, so you can see two inflorescences with mostly red bracts.

¿Estamos de acuerdo que ya le cayó caca al pastel del mundial? Desde las deportaciones masivas, pues, pero con lo de los bombardeos en Caracas por Estados Unidos y el aparente secuestro de Maduro, no hay forma de que ésto se pueda realizar de forma vagamente funcional.

Sheinbaum debería de sacar a Mexico del Mundial en protesta de esta invasión.

No podemos ser participes de las Olimpiadas de Berlin de 1936 modernas.

Apoyar a la propaganda del “Premio FIFA de la Paz” de Trump seria escupirle a toda la gente de este país.

Fox News sycophants framing things more accurately than Reuters—"those fluent in the good grammar of civility have deployed decorum to mask agendas of cruelty."

May the Republican and neoliberal regime crumble, its enablers and bystanders be cast out in disgrace and shame, and Monroe Doctrine die!

Trump says "something is gonna have to be done" about Mexico and President Claudia Sheinbaum in response to a question about whether the Venezuelan strike was a "message" to her government.

This is a thread of major media outlets falsely anthropomorphising the "Grok" chatbot program and in doing so, actively and directly removing responsibility and accountability from individual people working at X who created a child pornography generator (Elon Musk, Nikita Bier etc)

#1: Reuters
Grok says safeguard lapses led to images of 'minors in minimal clothing' on X By Reuters January 2, 20267:40 PM GMT+1Updated 1 hour ago Illustration shows xAI and Grok logos xAI and Grok logos are seen in this illustration taken, February 16, 2025. REUTERS/Dado Ruvic/Illustration Purchase Licensing Rights, opens new tab Jan 2 (Reuters) - Elon Musk's xAI artificial intelligence chatbot Grok said on Friday lapses in safeguards had resulted in "images depicting minors in minimal clothing" on social media platform X and that improvements were being made to prevent this. Screenshots shared by users on X showed Grok's public media tab filled with images that users said had been altered when they uploaded photos and prompted the bot to alter them. "There are isolated cases where users prompted for and received AI images depicting minors in minimal clothing," Grok said in a post on X. "xAI has safeguards, but improvements are ongoing to block such requests entirely." "As noted, we've identified lapses in safeguards and are urgently fixing them — CSAM is illegal and prohibited," Grok said, referring to Child Sexual Abuse Material. Grok gave no further details. When contacted by Reuters for comment by email, xAI replied with the message "Legacy Media Lies". In a separate reply to a user on X on Thursday, Grok said most cases could be prevented through advanced filters and monitoring although it said "no system is 100% foolproof," adding that xAI was prioritising improvements and reviewing details shared by users.

For two whole days Trump's comments on local NYC talk radio just hung in the air without question. The President of the United States claimed a strike on a country with whom we are not at war, and 48 hours passed without a peep. That says a lot about our media environment.

Im profoundly committed to access as care, access as process. Some of you need to understand that since chatGPT etc have entered the fray, many profs are seeing truly detrimental effects on students' engagement, learning and community. Caring about that isn't ableist/being a cop/technophobic.

🐉 The book of the great sea-dragons, Ichthyosauri and Plesiosauri, [gedolim taninim] gedolim taninim, of Moses.
London, W. Pickering, 1840.

[Source]
Illustration of a fossilized sea dragon skeleton embedded in rock, featuring a long, segmented spine with vertebrae and scattered rib bones. Surrounding the spine are numerous slender, curved bone fragments, indicating the remains of an Ichthyosaurus or Plesiosaurus from the 1840 historical work on great sea dragons. The detailed engraving shows the fossil’s intricate bone structure and its natural rocky matrix, emphasizing the ancient marine reptile's skeletal form linked to the concept of mythical dragons.

We should ask why it’s so easy for terms and concepts like “Heritage American” and “Western Chauvinism” are met with earnest analysis and exploration while academic theory produced by Black scholars are summarily dismissed by people reading introductory texts if that.

Black and white historical illustration of a platypus (Ornithorhyncus paradoxus) standing on a riverside with rocks and reeds. The platypus is depicted with its distinctive duck-like bill, webbed feet, and a flat, beaver-like tail. The animal is shown in profile, facing left, with detailed shading highlighting its fur texture and water habitat. The background features a natural wetland environment, emphasizing the platypus’s aquatic nature. Text on the page identifies the species and the plate number "XIII." The illustration is from a 1922 French publication on venomous animals.

Just gonna say this again for games sphere cus we get the same question:

Networking doesn't mean schmoozing up to famous people, it means making friends with your peers. Then in 10 years, 20, one of you might be famous? And sure you're still helping each other cus well yeah friends.

Make. Friends.

Talking to one of these types at a con who asked how I 'got in' with so many 'famous writers' who I'd been talking to and I said "we made friends before anyone knew who we were decades ago by striking up interesting conversations and enjoying each other's company" and he kept re-asking the question.

They have come to the convention hoping to "break in" and then find themselves -- shocker! -- a "nobody in the book world." Yeah no shit! We all are! I have gently told guys like this a million times that it takes most of us *years* of hard work but they do not believe that could be true for them. +

Most people confuse subject expertise with instantaneous encyclopaedic recollection. If that’s what an expert is, then yes, LLMs can definitely replace experts. But thats not what subject expertise is.

One of many things the pro-AI crowd doesn't seem to understand is the very important distinction between academic scholarship and the production of papers. Of course they can be related but they're not necessarily the same thing
