Astrophysics Data System A powerful, streamlined new Astrophysics Data System

ui.adsabs.harvard.edu

rather niche but NASA ADS (+arxiv) has been the standard for about 30 years in Astronomy. An example to follow and yet no field does.

this bit is important to keep in mind and has much wider applications (unfortunately)

Precipitation from the Radiation Belts A look at a one of my co-authored papers on microbursts and why you might care... at least in a round about way.

Took a look back at a recent (by some definition) paper, translated the title from science -ees to English and talked about why the work is important: both to a space physicist and to the general public.

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.

totally! also curious to see what they have in mind for a longer, multi-level adventure, in terms of Directing it and how it'll be structured in the book

3,842 airborne A320 family aircraft.

“Analysis... has revealed that intense solar radiation may corrupt data critical to the functioning of flight controls.

A significant number of A320 Family aircraft currently in-service which may be impacted.”

Currently ~3,000 airborne A320 family aircraft.

great cover! (full disclaimer: I'm biased for being a solar physicist 😂)

In light of record submission rates and a large volume of AI-generated slop, SocArXiv recently implemented a policy requiring ORCIDs linked in the OSF profile of submitting authors, and narrowing our focus to social science subjects. Today we are taking two more steps:

I'm old.

If you're not, listen to this.

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. 🧪

Space weather isn’t just about lovely displays of the aurora. There is a very real impact on our technology too.
