    112: Life in Exclusion Zones & Every Single Character

    2026-09-10 | 1h 58 mins.
    What happens to life inside exclusion zones like Chernobyl? Is it good? Bad? Or something much more interesting? And what happens when you try to codify every single character from human language? Well, it definitely leads to some fascinating linguistic rabbit holes!
    Images we talk about:
    Przewalski’s horse (yes that’s how it’s spelled)
    Frogs
    Character U+FDFD
    Arabic Text
    Decorative U+FDFD's
    Tom's Favorite Use of Kashida

    We also learn about: Actually defining it made it creepier, the zone rouge, we an area of Earth uninhabitable from war, chernobyl release over 100 radioactive elements, they really need to name the zone of alienation the zone of doing taxes, the liquidators actually did a good job of stopping the spread, is this a rewilding experiment? Ella deleted emails to poach this topic, Przewalski’s horse (yes that’s how it’s spelled), technically feral vs wild horses, I’ve reached the nuance center of my nuance pop, why isn’t it my job so sample chernobyl frogs, nearly all pine trees near chernobyl were wiped out, “the selective pressures of radiation”, bright birds used up their carotenoids for color, we’re doing nuclear ecological biochemistry, god that was an ugly laugh, maybe its counterintuitive for the small things - no this one sucks, the slow horror of a lack of decomposition, the ecosystem is not rewilded it’s entirely new, the Korean DMZ is like an ecological semi permeable membrane, DMZ ecology research institute, the DMZ has 40% of Korea’s endangered species, it’s a pitstop along the east asian australasian flyway, endangered cranes have bounced back in the DMZ, the DMZ crane watch, the cranes and natterjack toad require human farming to thrive, synonyms of nuance and thrive, Baarter economy standing ovation, conflictful chicken, Unicode is the ISO standard for text on computers, ASCII’s 128 characters is surely enough right? why do you have a period accurate phone? it turns out other cultures want to use the computer, there are 159,801 characters in unicode, the basic multilingual plane sounds like startrek shit and it kind of is, I mean it’s not like it has cuneiform except it does, braille unicode exists for a reason, braille doesn’t just map one to one with letters it also has contractions, contracted braille is a stenography, tweeting more in japanese, 101,996 CJK characters, Max Woolf’s Big List of Naughty Strings, after Mamdani was elected I had to learn how to pronounce the bismillah, “Bismillah is the Przewalski’s Horse of this topic”, I said we shouldn’t dive into the history of a language halfway through a topic but fuck it, LR0’s terrific Arabic typography essay, arabic script can be perfectly justified, “the justification lives inside the words”, Kashidas stretching across a map made it click for Tom, maing the bismillah beautiful, we all just want to make text look cool, the ottoman printing press ban myth, the cursed lost printed quran, oh my god is this the unifying thing, weirdly internet explorer had kashida justification for 1 year? Inshallah you find on the internet what you’re exploring for.

    We also learn about: Astronaut school, “the mission is exploration and only a part of it is human spaceflight”, the telerobotic surgery was real, living in NEEMO, Cady learned to remove a gallbladder, “what is it that I have to remember is not being simulated well?”, oh the telerobotic surgery was happening under water, it’s about sharing what you’re learning at the same time, spending 11 days underwater, bedrest studies in hawaii are actually a toll and a service, communication is key even in space, trust us space food is going to get old, not every day of training is remove 10 gallbladders, putting yourself in the picture humanizes it, which way is up? sleep flashes from cosmic rays, liquid sensors in our neck make you pee when you lie down and reduce blood volume in space, you can’t cough to hide your pee on the ISS, the future of the ISS, astronaut feet facts, Paolo and Cady’s toenail system, learning to fly in zero g, “you learn to live in 3 dimensions”, losing things in zero g sucks, CO2 buildup for the group photo, not washing clothes upset the balance, it’s all about fluid physics, “it’s all about interfaces between solids and liquids - and up in space it’s the biggest game in town”, peeing in space is easier than camping, how you determine your space order with feet, the domino effect of space suit sizes, your space suit is your space ship, IT’S LESS MATERIAL, there are people who are still waiting their turn, “how do you make sure these voices are heard when their presence is not missed?”, how to work for change collaboratively, you shouldn’t have to work so hard to participate, “oh that’s going on the website Cady”, one small step for you and one big step for democracy.

    We also learn about: I’m taking horse pills to get their powers, we can answer questions without getting klaxonned, abbreviated for french reasons, the meter is 1 ten millionth the distance from the north to south pole, I’m going to be talking about power “oh god”, power is the movement of a mass over time, you’ll notice nowhere in that definition did I mention horses, James perfects the steam engine, you can’t just say “hey this engine will get us to the industrial revoltuion” you have to sell it in horses, come up with your own unit of power dweeb, a horse can produce 15 horsepower,  you’re about to have a lot more nickels, there was a metric and imperial horsepower, all the international names for hosepower, watt SI unit is on first base? the father son and the holy ghost of electronics (the amp, volt, and watt), we didn’t have a unified unit for power before horsepower, Thomas Edison measured lightbulb efficacy by horsepower, IT WASN’T AN IRONIC CHOICE IT WAS CAUSE AND EFFECT, this isn’t a podcast it’s a slumber party, Caroline and Ella’s metallic blue eyeliner/facepaint, webster’s definition is somehow too broad and too narrow, prehistoric pigemtns may have been body paint, Ella’s surprisingly informative ancient egyptian ASMR video, from kohl to green malachite, caroline hiding the sexy bits of the papyrus from us, this makes my tummy hurt, fish palettes, ancient greek prostitues were required to wear lipstick, modern man or ro-man, a woman buys lotions and perfumes with cheating in mind, Elizabeth I’s lead and vinegar makeup, painting on fake veins, plucking hairs to match the queen’s forhead, the optical illusion dot, Caroline’s favorite fad: beauty patches, it’s so wild how excluded darker complexions are in the market when this topic started in ancient egypt, perhaps makeup imitates the moment of an orgasm, im inventing new sexism: men are blurry, we finally just asked women why they wear makeup, wearing makeup because we have to vs we want to, for other or ourselves, the ro-manosphere.

    We also learn about: We almost do the same grim joke, the live show will have 50% more hosts than this, before publications there were societies and books and letters, in 1665 a Henry Oldenburg of the royal society starts “Philosophical Transactions”, the longest continuous journal (ignoring the time Olderburg was put in a tower for criticizing the king), the discovery of Jupiter’s red spot and also a deformed calf, Newton’s Optics was published in Philosophical Transactions first, Science has bad SEO, the doubling time of papers is 14 years since the 1950s, Ella’s peer review process, errors can be missed and biases affected, not paying reviewers is a bug that’s labelled as a feature, government funded research can still be privately owned, we’ve all agreed “processing fee” just means bullshit, there’s some things I don’t want to be “fun”, Elsevier has a 38% profit margin while Alphabet’s is 32%, editorial resignations in protest, I’m excited to add Robert Maxwell to my Arya Stark list of people, Maxwell died on his yes-that-Ghislaine-Maxwell Yacht, the scheme to buyout scientists for their papers, cover upfront costs - own copyright - flood with new journals - reap the subscription costs, “jesus wept”, retractions are growing by about 20% each year, I’m buying Ella a dictionary so she can learn what “fun” means, fool me 239 time shame on me, paper mills, predatory journals are pay to win, the Chinese restaurant metaphor keeps staying accurate, no it’s not nature our journal is nurture, is this finally rock bottom? the public review curate model, the pros and cons of preprints, diamond open access, the nelson memo, “I think the Ghislaine Mawell death yacht is fun”.
