Expected to find sandy beaches and found large boulders?

#OSIRISREx's encounter with asteroid Bennu resulted in a mystery for scientists who tried to understand why the asteroid didn't behave thermally the way they expected, based on what the spacecraft saw during their encounter.

The rock samples brought back to Terra held the answer to the mystery. Here's a cool graphic as an appetizer for the article.

I have a new, long-ish post on Alfred Korzybski's use of his map metaphor (nowadays simplified as "the map is not the territory"). And what I now see as its confusions! Enjoy!!

My favourite piece of internet today is the theory that Jesus was actually a type of yeast.

Turns water into wine
Floats on water
Makes bread for 5000 people
Put in a cave for 3 days and lo - he has risen!
Jesus was a sourdough starter.

Also this would imply: We should be calling him 'Mother' not 'Father'

I’m launching #QwastTube: a #PeerTube‑based, privacy‑friendly alternative to my YouTube channel.
If you care about digital sovereignty and open‑source GIS, this is for you.

I’m still importing videos, but it’s already live:

YouTube will stay in sync for now, but I hope you’ll join me on the fediverse.
