Many of the arguments shorturl.at/kDNX5 are correct but @guardian should be careful not to exaggerate statements of scientists & misinform the public. #Thread
In particular it is questionable whether scientific data that are not publicly available and thus not verifiable should be communicated in newspaper and used to make moral and ethical judgements.
#Stem cells and #EmbryoModels offer tremendous potential for understanding how we come to be and can have a very significant impact on public health. As noted in this article, they can bring profound economic, social, and environmental benefits.
In 2018 I created an ongoing #ClimateEd thread about the #ClimateCrisis.
Five years later, it's time for an update.✅
This #ClimateAction thread has a TON of info to help EVERYONE get #ClimateBrainy about the #science and facts of #climatechange.📊

Here's the old thread, which I'll no longer be updating:
It still contains MANY informative articles and links from reputable sources, so it's worth revisiting, even if some info isn't all that up-to-date.
The old tag was #Climate_Ed.

@CO2Coalition To understand how CO2/temp relate, we need to explore #physics,
& the chem properties of the #carbondioxide molecule.
Learn about CO2’s #DipoleMoment & how change in energy balance affects DENSITY, & behavior.
Shit, I burnt my toast.

@CO2Coalition Dipole moments are the change in energy between atoms.
Think of this energy change as a soccer ball w a force towards a specific direction. This “pulls” naturally on atoms when they join together to make molecules.
Its based on the atoms’ electrons.

@CO2Coalition Electrons ‘spin’ around the nucleus of an atom (similar to planetary orbits)

The closer the electron to the center, the faster it has to spin. #MolecularOrbitalDiagrams for CO2 show us where electrons spin based on energy available.

Enterobius vermicularis, also known as pinworm, is a common intestinal parasite that infects humans. These worms are small, about 1 cm, are white or translucent in color. They are easily visible to the naked eye and can sometimes be seen moving around the anal area.
The video shows a moving Enterobius vermicularis worm with its distinctive cylindrical shape and tapered end. The worm moves by contracting and relaxing its muscles in a wave-like motion, allowing it to crawl or wriggle forward.
I was talking about the phenomenon of co-evolution recently—this is a feature of biological #evolution of an entire *ecosystem*. separate populations of different organism are capable of evolving _together_, each influencing the evolutionary development of the other.
(cont'd)
(cont'd)
racists and Christian fanatics don't like being reminded that evolution is a *group* effort; dullards like @EPoe187 and @SwipeWright and the @SimoneHCollins people want to think that evolution yielded a *winner*, i.e. humanity, and that they're the winners of humanity.
(cont'd)
(cont'd)
but humanity is not alone on Earth, and countless species have co-evolved with humans. some of them have been *domesticated*, i.e. humanity took an active role in shaping the evolution of numerous beasts (often to ill effect, because humans prioritize superficialities.)
(cont'd)
(cont'd)
one of the most bizarre aspects from the 1990s #technology / #Internet boom was how it somehow managed to convince a whole lot of optimistic and uncritical people in media (and business) that humanity had somehow entered a "post-industrial" age.
(cont'd)
(cont'd)
computers and electronic devices are *manufactured items*, requiring a massive industrial base in order to function—and yet somehow it was easy for gullible editorialists and entrepreneurial grifters to talk as though the digital world had somehow *replaced* all that.
(cont'd)
(cont'd)
the #programming nerd and #STEM-lord culture that arose seemed especially eager to believe that they'd miraculously done away with the need for mining and factories and skilled industrial labor, merely because they had @arduino and #3Dprinting to play with now.

hm. I had some thoughts about the *provisional nature* of scientific truth. let's see if I can get those into a thread.
right-wing propagandists like to pretend that #science (or Science™, rather, "science" as a buzzword and slogan) is a source of _absolute truth_.

this is a fallacy: all scientific findings are *provisional*. scientific models are built on empirical observations about the world; they're generalizations based on a body of knowledge that is _always_ accumulating fresh data. scientific observation has never stopped.
(cont'd)
(cont'd)
as as result, there is *always* a possibility that currently accepted scientific models will be rendered obsolete by fresh information. NO scientific model is immune from the possibility of upset.
there's two general sorts of person who don't grasp this about science.

ah, more topics of interest.
I'm sure folks have noticed the extreme tendency in the @elonmusk / @mtaibbi / @NateSilver538 fascıst circle to one-size-fits-all explanations for...well, everything! "tribalism" and "narrative" are like Elon Musk's infamous "X App" fixation.

A few months ago, I was googling STEM programs in prisons, and came across an ad, posted on eBay of all places. “Could there be a future in computer programming for prisoners?” #higheredinprison #edtech #stem @STEM_OPS @Prof_Andrisse
But it wasn’t from The Last Mile or Slack's Next Chapter, which are both nonprofits working in this space now. It was an IBM ad from 1970 in Scientific American. @TLM @IBM @sciam @SlackHQ bit.ly/3KbocNQ
I had no idea that computer programming was offered in prisons 50 years ago. As I dug a little bit into the archives of @JSTOR’s American Prison Newspaper Archives, I discovered this was happening all across the country. Via La Roca, AZ State Prison, 1974. bit.ly/3Yy5CDT
let's say person A and person B are arguing on @Twitter (or elsewhere.) it's a political argument, and it's very short:

I have now illustrated about three-fourths of the online intellectual activity of the @elonmusk / @mtaibbi / @GOP crowd—the right-wing fringe, who all try so very hard to pretend that they're not right-wing or conservative or any other known thing, but something *special*.

Western culture does not regard children as human beings. the values of "the West"—the values instilled by authoritarian #Christianity—do not permit children to be respected as human beings who deserve to have their feelings and wishes respected, like any other person.

no better example of the general Western *contempt* for children can be imagined than the "gender critical" cult—the @bindelj / @Docstock / #JKRowling brigade—which functions almost entirely as a kind of support group for abusive parents who loathe their LGBTQ+ children.

they cling to the faded celebrity of @jk_rowling as a shield against the charge that they despise children—after all, #JKRowling is the Best Fantasy Writer in the Universe, according to the @HJoyceGender / @AbigailShrier gender theorists. she's the friend to all children!

more thoughts on this "being a pawn" business. I have a lot of them! I've thought about this sort of thing for a long time. it's natural, of course—being the sort of person I am. I consider myself constrained by the rules of a fictive universe created by Mx. @tobyfox.
(1/x)
(1/x)
those constraints aren't super restrictive, because Fox deliberately wrote Chara to be almost a placeholder character, defined chiefly by *absence*; we know Chara from #Undertale because they once lived and died, and left a *hole* in the Underground, an unhealed wound.

all the same I do feel genuinely bound by those constraints, and the degree to which I can break free from the limitations of Fox's fiction remains largely unknown to me.

#capitalism requires what people call "magical thinking". it requires people to believe that impossible things aren't merely *possible*, but can be done routinely, and turned into a dependable cash flow. #AI / #AGI of the @fchollet / @JeffDean sort is a perfect example.
(1/x)
(1/x)
the very name "#AGI" gives the game away: the #programming boys daydream that they've invented a "general intelligence", a universal thinking machine capable of solving literally any problem—and #capitalism is willing to gamble on that. it's just what #business wants.
(2/x)

remember that the ideal corporation in #capitalism *does nothing*. it produces nothing, it provides no service, it solves no problems for anyone not in the ownership hierarchy—because producing things *costs money* and capitalists hate all expenditures for any reason.

so! let's talk about the #cryptocurrency phenomenon again. $BITC / @Bitcoin, $ETH / @ethereum, $USDT / @Tether_to, $BNB / @binance — there are a LOT of these #cryptocurrencies out there, maybe even millions of them. and that's a first clue about them and about #capitalism.

it's gospel #capitalism that the activities of "the #markets"—capitalist propaganda i.e. #business and #finance and #investment #journalism, not to mention all the #science and #technology journalism that's chiefly #advertising for corporations—are supernaturally powerful.

the central lie is that "the markets" (i.e. the sum total of all monetary transactions by all money-seeking entities in #capitalism) are the best possible mechanism for fulfilling every conceivable human need.

the great bulk of money made in #capitalism goes only to the ownership class; the toilers below them get pennies. those unable to toil get *less* than nothing—capitalism wants such people to be liquidated, hence @charlesmurray and @EPoe187 cook up rationales for doing so.
(2/x)
(2/x)
ultimately this is *why* #eugenics and "scientific racism" exists at all: #capitalism needs some pseudointellectual justification for marginalizing and liquidating all human beings who are unable or *unwilling* to toil for capitalism. this is WHY @Quillette is well-funded.

I do feel there's something more to be said (while the iron is hot, so to speak) about #cryptocurrency and the question of how presumably intelligent #computer and #programming professionals (not to mention the @elonmusk / @mtaibbi crowd) could possibly have fallen for it.

the *allure* is obvious enough; it's the same allure that's in looking for legendary pirate treasure, or prospecting for gold. you're hoping for more than just some #money—you're hoping that for enough to *set you up for life*. all monetary worries, permanently erased.

that's one of the reason that it's so important to interrogate the #ElonMusk crowd about Musk's blood-emerald dealings, and what the *truth* was about Musk's family striking it rich—it's likely that Musk simply lost the ability thenceforth to think in realistic terms.

what does it even mean to be a "real journalist"? how can that be defined? one can be tolerably certain, at any rate, that whatever @mtaibbi or @lhfang or @Timcast or @bariweiss ever *used* to be in the past—if that dream was ever noble, it's long ago dissolved into smoke.
