Steve Mould has a knack for turning everyday curiosities into miniature engineering lectures. Here he shows how wire electrical discharge machining (wire EDM) erodes metal with pinpoint accuracy, creating cuts so fine they're measured in microns. A masterclass in how science turns physical limits into design possibilities, full of those 'oh, so that's how it works' moments.

Which letters
What's the difference?

The Grokkist letter is Danu's monthly letter about the whole Grokkist community: what people are making and thinking about, gatherings coming up, and a handful of Snackables, small good things worth your time.

The Press sends you new writing from this site as it's published (essays, talks, stories, books in instalments), plus a monthly letter from the editor. You can narrow it to the Realms you care about.

What are the Realms?

Every piece in the Press lives in one or two Realms: regions of the Grokkist world, each asking for a different kind of attention. Pick the ones that draw you, and you'll only hear about pieces from those.

  • Unfolding Realm: identity and becoming
  • Entangled Vale: shared inquiry and making sense together
  • Maker's Forge: creative expression
  • Soma Isles: the body and embodied practice
  • Wild Margin: changemaking and possibility
  • Hearthlands: community and connection
