What's Earth's dominant species by mass?
You might have heard that all the ants in the world weigh as much combined as all the humans. That isn’t true. We outweigh ants 5 to 1.1 Termites might have us beat, though.2 Either way, it’s not r…

The paper computer
Now that we have actually good AI, I have this vision of a form of computing that doesn’t involve me using a computer so much. Imagine you had the day’s emails to go through. It would be nice if the ones that required a simple decision could be dispatched with a few pen-strokes: I could write down a date that would…

An old patent inspired the new "Y-zipper", a three-sided fastener
A new system developed at MIT CSAIL helps users design three-sided fasteners called “Y-zippers,” then 3D prints them. The devices can be attached or embedded to camping equipment, medical gear, robots, and art installations, seamlessly switching each item between soft and rigid.

I'm scared about biological computing
I’ve been in the AI space since ChatGPT first dropped. I’ve toyed around with a lot of Language Models, built random side projects, built a couple from scratch and I’ve spent hours looking at the math behind it all.

Aluminum foil (2021)
It’s typically 10 μm thick and 400 mm wide, giving it an aspect ratio of 40000 in that dimension, and rolls are commonly some ten meters in length, for an aspect ratio of 1 000 000; heavy-duty versions can reach 30 μm or more. Despite their thinness, foils of 25 μm or more are impermeable to oxygen, water, and light…

So you want to build a tunnel
[Note that this article is a transcript of the video embedded above.] It seems like homemade tunnels are kind of having a moment. Just about everywhere I look, it feels like someone is carving new spaces from the ground and documenting the process online. Colin Furze might be the quintessential ex

Mystery of 60-Second Fluctuations in Power Grids Solved
Why do our grids show a brief spike in electricity demand every minute? A team led by Dirk Witthaut from Forschungszentrum Jülich has now demonstrated that this is due to regular power checks carried out by large-scale battery storage systems. These findings could help to make our electricity supply more robust, as…
