Everyday Objects Are Unrecognizable at Super Macro Scale

Posy takes us on a grand adventure into the world of the incredibly small and ridiculously close.

Prepare to sit in awe of everyday objects from an entirely new perspective.

Funny, we should probably try to look at the world from different perspectives more often…

We must build AI for people; not to be a person

My life’s mission has been to create safe and beneficial AI that will make the world a better place. Today at Microsoft AI we build AI to empower people, and I’m focused on making products like Copilot responsible technologies that enable people to achieve far more than they ever thought possible, be more creative, and feel more supported.

I want to create AI that makes us more human, that deepens our trust and understanding of one another, and that strengthens our connections to the real world. Copilot creates millions of positive, even life-changing, interactions every single day. This involves a lot of careful design choices to ensure it truly delivers an incredible experience. We won’t always get it right, but this humanist frame provides us with a clear north star to keep working towards.

Some thoughts from Mustafa Suleyman on building AI that doesn’t convince people that AI is a human, or needs rights. Or is a god.

Sadly, we’re already having those discussions.

You Might Be Trying to Replace the Wrong People with AI

I was at a leadership group and people were telling me “We think that with AI we can replace all of our junior people in our company.” I was like, “That’s the dumbest thing I’ve ever heard. They’re probably the least expensive employees you have, they’re the most leaned into your AI tools, and how’s that going to work when you go 10 years in the future and you have no one that has built up or learned anything?

So says Matt Garman, CEO of Amazon Web Services. A better question to ask: What do you mean, you don’t want to teach your high school students how to use AI to help them write code and solve problems more efficiently?

We live in weird times when people constantly retreat to what came before and avoid any intention of moving on.

Life is the future, not the past.

Black, Latino & Low-Income Kids Felt Better Doing Remote School During COVID

The dominant story about COVID-era school closures has been simple: remote learning hurt kids’ mental health. And for many, that’s true. National data show American teens reported more loneliness and more suicidal thoughts between 2019 and 2023, with isolation during lockdown often cited as the culprit.

But a new study complicates that narrative. Researchers analyzed survey data from more than 6,000 middle schoolers during the 2020–21 school year and found a striking divide:

White and higher-income students were significantly happier and less stressed when attending school in person.
Black, Latino, and low-income students often reported the opposite—feeling less stressed and sometimes even happier when learning remotely.

In other words, remote school wasn’t universally worse. For some groups, it offered a reprieve from stressful in-person school environments, from health risks during the pandemic, or from inequities baked into the classroom experience.

The findings don’t suggest remote school is “better” overall. Academic setbacks during closures were real and disproportionately hurt the very students who sometimes felt mentally healthier at home. Instead, the study is a reminder that school isn’t a neutral space. How students experience it depends deeply on race, income, and environment.

As the researchers note, it’s not enough to flatten the pandemic into a single story of harm. Different groups of students experienced it differently—and will need different supports moving forward. If schools want to be places where all kids can thrive, they’ll need to reckon with why in-person learning left some students more stressed than staying home.

2,178 Digitized Occult Books: Strange Treasures for Authentic Learning

In 2018, Dan Brown (yes, that Dan Brown of The Da Vinci Code) helped fund a project at Amsterdam’s Ritman Library to digitize thousands of rare, pre-1900 books on alchemy, astrology, magic, and other occult subjects. The result, cheekily titled Hermetically Open, is now live with 2,178 digitized texts—freely available in their online reading room.

At first glance, this might feel like a niche curiosity, the kind of thing best left to academics or fantasy novelists. But the truth is, these works are a goldmine for educators looking to spark authentic learning across disciplines. They’re messy, strange, multilingual (Latin, German, Dutch, French, and English), and they blur the boundaries between science, philosophy, medicine, and mysticism. And that’s exactly why they’re valuable.

Why Teachers Should Care

For a few hundred years, it was nearly impossible to separate theology, philosophy, medicine, and natural science from alchemy and astrology. Isaac Newton himself famously spent as much time on apocalyptic prophecies and alchemical experiments as he did on calculus and optics. To engage students with these texts is to remind them that knowledge has always been interdisciplinary, networked, and evolving.

That makes them perfect material for authentic learning and connectivist classrooms: students work with primary sources, make connections across fields, and grapple with how humans have always sought to explain the world.

How Different Subjects Can Use the Collection

English & Literature (HS & College):

Analyze archaic language, quirky spellings, and “long s” typography in original texts.
Compare occult poetry or allegories to Romantic and Gothic literature.
Use passages as mentor texts for student-created “modern grimoires” or magical realism writing.

History & Social Studies (MS–HS):

Trace how alchemy influenced the rise of modern chemistry.
Explore how astrology shaped political decisions in early modern Europe.
Debate the blurred lines between science and mysticism in intellectual history.

Science (HS Chemistry & Physics):

Contrast alchemical “recipes” with modern chemical equations.
Investigate how flawed models of the universe still paved the way for discovery.
Discuss how cultural context shapes what gets counted as “science.”

Art & Design (All Grades):

Study illuminated manuscripts and esoteric symbols as design inspiration.
Create modern visual interpretations of alchemical diagrams.
Explore symbolism as a universal language across time.

Philosophy & Civics (HS & College):

Debate the tension between hidden vs. open knowledge.
Compare Platonic philosophy, Christian theology, and occult traditions.
Examine how fringe ideas challenge (and sometimes advance) mainstream thinking.

Why It Matters

When students encounter these texts, they’re not just paging through dusty old curiosities. They’re stepping into a world where knowledge wasn’t siloed, where science, spirituality, and imagination lived side by side. For teachers, this is a chance to create assessments that matter—projects where students remix history, art, and science, using both ancient texts and modern tools like AI.

It’s weird. It’s wonderful. And it’s exactly the kind of resource that can make authentic learning feel alive.

Steve Wozniak Never Sold Out

I gave all my Apple wealth away because wealth and power are not what I live for. I have a lot of fun and happiness. I funded a lot of important museums and arts groups in San Jose, the city of my birth, and they named a street after me for being good. I now speak publicly and have risen to the top. I have no idea how much I have but after speaking for 20 years it might be $10M plus a couple of homes. I never look for any type of tax dodge. I earn money from my labor and pay something like 55% combined tax on it. I am the happiest person ever. Life to me was never about accomplishment, but about Happiness, which is Smiles minus Frowns. I developed these philosophies when I was 18-20 years old and I never sold out.

Teaching the Unmappable: Why Color Defies Easy Charts

For centuries, scientists, artists, and philosophers have tried to pin down a “perfect” way to map color. But here’s the problem: color isn’t just physics, and it isn’t just perception—it’s both. Try to squeeze it into a neat geometric model, and you’ll quickly realize it refuses to stay put.

That’s what makes French video essayist Alessandro Roussel’s latest ScienceClic piece so fascinating for educators. He takes us from Isaac Newton’s prism experiments all the way to modern models of hue, brightness, and saturation. Along the way, he shows why there isn’t just one map of color, but many. Each communicates something different about how humans experience this slippery phenomenon.

So what’s the classroom connection?

In art: Students can compare different models of color—Newton’s circle, Munsell’s tree, the modern RGB cube—and reflect on how each changes the way we think about mixing, matching, or designing with color.
In science: Teachers can use these models to illustrate how physics collides with perception. Why do two people see the “same” red differently? How does light wavelength interact with the human eye and brain?
In interdisciplinary projects: Color mapping opens doors to conversations about how humans create systems to explain the unexplainable. It’s a perfect bridge between STEM and the humanities.

And then comes the kicker for students who think we’ve “solved” everything already: scientists recently managed to engineer a new, so-called impossible color called ‘olo’—a shade outside the traditional visible spectrum.

It’s a reminder that color isn’t just a solved equation or a finished wheel. It’s a living, shifting puzzle that still invites curiosity, wonder, and experimentation.

Imagine giving your students that as a challenge: If color can’t be mapped perfectly, what’s your best attempt?

Can an App Cure Math Anxiety? Duolingo Thinks So.

Most of us have heard (or said) the phrase: “I’m just not a math person.”
Duolingo—the same company that made millions of people practice Spanish while waiting in line at Starbucks—is on a mission to change that story.

You probably know Duolingo as the language app with the slightly unhinged green owl who won’t let you forget your streak. But since 2022, Duolingo has been quietly building something new: a math course. And just like its approach to languages, the company believes it can make math more approachable, less intimidating, and maybe even fun.

Why Math? Why Now?

According to Samantha Siegel, the engineer leading Duolingo’s math push, the choice to focus on 3rd grade and up wasn’t random. Around that age, kids hit fractions—and that’s where things start to go sideways for a lot of learners. Fractions are a gateway. Struggle there, and the rest of math often feels like a foreign language.

Duolingo’s idea: treat math like a language. Build fluency through small, repeatable practice. Create low-stakes games. Give immediate feedback. And—most importantly—reduce the anxiety that creeps in when kids (and adults) start believing math is beyond them.

How It Works

If you’ve ever tapped your way through Spanish verbs or French phrases, the math experience feels familiar—but with some clever twists:

Dynamic problems: Lessons refresh with new numbers every time, so you’re not memorizing answers—you’re actually practicing.
Interactive input: Instead of multiple choice, you might drag the corners of a rectangle to measure area, or handwrite a fraction into the screen.
Visual learning: Geometry isn’t just explained; it’s something you manipulate on the screen.

In other words, the app tries to ground abstract math ideas in movement, visuals, and play.

Tackling Math Anxiety Head-On

Here’s the thing: math anxiety is real, and it’s not just about ability—it’s about confidence. When kids (or adults) tense up at the first sight of an equation, their brains literally struggle to process what’s in front of them.

Duolingo’s bet is that by gamifying the experience, they can lower the stakes. Just like the app makes it totally fine to get a French verb wrong, it’s trying to make it okay to fumble a fraction. In a classroom context, that shift could matter—a lot.

Where It Stands Today

The math course is now baked right into the main Duolingo app, alongside language and even music lessons. Learners can keep their streak going across subjects—whether they’re conjugating verbs, strumming chords, or multiplying fractions. Duolingo hasn’t shared exact numbers, but we’re talking millions of math users already.

And it’s not just for kids. Plenty of adults are using it too—either to brush up on long-forgotten basics or to help their kids without pulling out dusty textbooks.

What This Means for Educators

Is Duolingo going to replace teachers? Of course not. But as a supplemental tool, it’s promising. It gives students a way to practice math outside the classroom that feels a lot more like a game than homework. It also gives parents an accessible, non-threatening entry point into supporting their kids’ learning.

The bigger story here is the attempt to reframe math itself. If Duolingo can help chip away at the “I’m not a math person” narrative—if it can make math feel just a little more like a game and a little less like a stress test—that’s a win.

Final Thought

Duolingo isn’t just teaching fractions and geometry; it’s trying to rewrite how learners feel about math. And in a world where math anxiety holds so many students back, that mission might matter even more than the streaks.

Maybe, just maybe, the next time someone says “I can’t do math,” we’ll have an owl to thank for proving them wrong.

Neuromancer: The book that jailbreaks the future

Blistering verdict: Neuromancer doesn’t predict the future—it jailbreaks it. William Gibson plugs you into a neon-slick, rain-slicked world where data has gravity, money moves at the speed of light, and the line between human and machine is just another corporate asset to be negotiated. It’s fast. It’s razor-sharp. And four decades on, it still crackles like a live wire.

Spoiler-free recap (no ICE burned, promise)

Meet Case—a burned-out “console cowboy” who once rode the matrix like a god until he crossed the wrong people and lost the only thing that mattered: his ability to jack in. He’s offered a dangerous second chance by a mysterious patron with deep pockets and deeper secrets. Enter Molly, a mirror-shaded street samurai with retractable razors and zero patience for anyone’s nonsense. The job? A multilayered, globe-hopping (and orbit-hopping) heist threading megacorps, black-market biohacks, and an AI problem that’s less “glitch” and more “philosophical earthquake.”

The plot moves like a hot knife through black ice—tight, propulsive, and always one layer more ambitious than you think. Every chapter ups the stakes; every alleyway has a camera; every ally might be a contractor. You don’t need spoilers. You need a seatbelt.

Why this book still matters (and why geeks keep handing it to friends)

It gave us our mental model of the net. Gibson’s “cyberspace” isn’t just a word—it’s an interface, a mythos, a feeling. The luminous grids, the consensual hallucination of a shared data world? That’s the cultural operating system we installed long before broadband.
It forged the cyberpunk aesthetic. Street-level grit meets orbital decadence; chrome and sweat; hackers and mercenaries threading the seams of empire. If you love The Matrix, Ghost in the Shell, Cyberpunk 2077, or Mr. Robot, you’re drinking from this well.
It nailed corporate power as world-building. Megacorps behaving like nations. Security as religion. Branding as surveillance. In 2025, tell me that doesn’t feel uncomfortably like a user agreement we all clicked.
It treats AI as character, not prop. Neuromancer asks the questions we’re still arguing about in boardrooms and labs: autonomy, constraint, alignment, and what “self” means when the self can be copied, merged, or monetized.
The prose is pure overclocked poetry. Gibson writes like he’s soldering language: compressed, glittering, and purpose-built. The sentences hum; the metaphors bite; the world feels legible and alien at once.

What hits different in 2025

Identity as a login. Case isn’t just locked out of systems; he’s locked out of himself. That anxiety—who are we without access?—is the backbone of our cloud-tethered lives.
The gig-hacker economy. Contractors, fixers, “teams” assembled like temporary code branches. It’s Upwork with thermoptic shades.
Biohacking & upgrade culture. From dermal mods to black-clinic tune-ups, the book treats the body like firmware—exactly how today’s wearables, implants, and nootropics culture wants you to think.
Algorithmic power. Replace “AI” with your favorite recommendation engine and the social physics hold: it watches, it optimizes, it nudges. The ethics still sting.

How to read it (and love it)

Surf the jargon. Don’t stop to define every acronym. Let the context teach you like you’re a rookie riding shotgun with veterans.
Trust the city. The settings—Chiba City, the Sprawl, orbit—are more than backdrops; they’re tutorial levels. Watch what they reward and punish.
Hear the bassline. The book is paced like a heist film. When it slows, it’s loading a bigger payload. When it sprints, hang on.

If you’re this kind of reader, this book is your jam

You love high-concept, high-velocity fiction that respects your intelligence.
You care about tech culture’s DNA—where our metaphors and nightmares came from.
You’re a world-building nerd who wants settings that feel lived-in, not wallpapered.
You’re into AI, hacking, and systems thinking and want a story that treats them as more than shiny props.

The influence blast radius

Neuromancer is ground zero for the cyberpunk sensibility: the hero is small, the system is massive, and victory looks like carving a human-sized space in a machine-sized world. Its fingerprints are everywhere—console cowboys inspiring dev culture; “ICE” as the vibe under every security audit; fashion, music, and UI design that still chase its cool. Even the way journalists write about breaches and “entering the network” leans on Gibson’s visual grammar. Read it and you’ll start seeing the code behind the cultural interface.

After you jack out: what to read next

Count Zero and Mona Lisa Overdrive (finish the Sprawl Trilogy—richer world, expanding consequences).
Burning Chrome (short stories that sharpen the vision).
Adjacent canon: Neal Stephenson’s Snow Crash (satire-powered rocket fuel), Pat Cadigan’s Synners (media and minds), and Rudy Rucker’s Ware series (weirder, wilder, wonderfully so).

Final verdict

Neuromancer is essential reading—full stop. It’s the rare novel that changed the language we use to talk about technology and remains a pulse-pounding ride. If the Internet is the city we all live in now, Gibson drew the first street map that felt true. Pick it up for the thrills; keep it on your shelf for the ideas that won’t let you go.
