Muons are short-lived subatomic particles, same charge as an electron but ~200 times more massive. On Earth, they're produced by cosmic rays colliding with the upper atmosphere, and they hit the ground at a rate of about ten thousand per minute per square meter.

They're moving extremely fast at ground level, like 0.99 c. So they careen right through matter, deflecting only very slightly around heavy atomic nuclei – they'll penetrate like a hundred meters into solid rock.

What do you do with this continuous shower of deep-penetrating charged particles, constantly blanketing every square inch of the Earth's surface?

The classic thing is use them to image the inside of massive structures, like we use x-rays to look inside living tissue – except instead of generating them yourself, you just use atmospheric muons. Muon archeology is a whole thing, they've used it to find hidden chambers in pyramids and stuff. Neat!

But this one Estonian company is doing some crazy bullshit and I love it.

Sandwich anything between a pair of portable muon detectors and get full 3D imaging of the interior, with sub-millimeter accuracy, by tracking the minute deflection of muons between them. Samples that are WAY too thick for x-rays, made of literally anything. Just put some muon detectors on some two by fours in a warehouse and call it a day.

You can just. Image anything??? Anything you want?? Completely passively!! Just detectors! No particle source! Put them anywhere. The detectors themselves are a mature technology, the company's tech is in the algorithms they use to get this level of spatial and elemental resolution.

You can detect failures inside cable-reinforced concrete bridges without cutting open the bridges.

Decommissioned Soviet nuclear submarine filled with concrete, with no drawings or documentation, that may or may not have spent fuel canisters in it? And you need to cut it up for storage? Just look at the muons.

One of the wackiest ideas is to put one detector under your bed and one on the ceiling, so you get a full 3D scan of your body every night, passively. I want one.

This is bat friendly street lighting, which not only looks sick as fuck but allows bats to pass through without disturbance, as they cannot see red.

This never occurred to me. Not once. That Americans are against Health Care because they think it actually costs tens of thousands of dollars for a broken arm, hundreds of thousands for a complicated birth, millions for cancer treatment.

I’ve had these same drops before living in the UK. They cost me seven GBP.

It’s the exact same drug, same steroid, same strain of antibiotic. But somehow the US gets away with charging $100 for a generic non brand version of a drug which is easy to create and widely used. It’s downright robbery, but also a form of eugenics through poverty and class warfare. You keep the poor poor by making sure basic necessities remain unattainable and then you make it seem like the norm so no one fights it.

The rest of the world is not like this.

I’m in the exam room, post diagnosis and with pill bottles in hand, and in walks the one nurse I’ve been able to speak to the entire time. She pats my hand and tells me (and this is verbatim—I will never forget this conversation as long as I live), “I’m so sorry. We had to run those tests, and they are expensive. You don’t have insurance so you will have to cover the full cost.”

I start crying.

She continues, softly, as if telling me someone has died, “It’s going to be three hundred.”

I start sobbing, certain I’ve misheard, certain that I would be absolutely fucked, broke and going into debt in a foreign country. “Thousand?” I clarify.

Her entire demeanor changed, and she looked at me as if I had sprouted four extra heads. “No,” she says, “euros.”
