In ancient Mesopotamia, astronomers needed to know the moon’s position, even on a cloudy night.
So they made records and calculations of the moon’s positions and velocity measured in degrees. This record from Uruk or Babylon from the Seleucid period covers 248 days.

a good and short thread on the recent flight issues with solar energetic particles 👇
A big day for space weather, with the BBC reporting that a Mexico-to-USA flight in October experienced a 'sudden drop in altitude', likely caused by *solar energetic particles* from the Sun. Here is an explanation and some thoughts as a solar astrophysicist (a thread): 1/8

Get a guitar or some drums, or a trumpet. Pick up a brush, a pencil, some clay or a welder.
Just make shit. It doesn't have to be good (eventually it will be) just make music, art or write or whatever.
It's literally never been more important.

Journalist challenge: Use “Machine Learning” when you mean machine learning and “LLM” when you mean LLM. Ditch “AI” as a catch-all term, it’s not useful for readers and it helps companies trying to confuse the public by obscuring the roles played by different technologies. 🧪
