My ‘albatross’ paper is finally out! So much gratitude to @luiswel.bsky.social for helping me turn three years’ worth of hard-graft writing into something I am really proud of, and to the editorial team at Living Reviews in Computational Astrophysics team for their (substantial!) patience.

I know there was a lot going on in American politics today, but I wanted to take a moment to highlight how much I admire the work that Greta Thunberg and the Freedom Flotilla are doing. They're sailing an aid ship across the Mediterranean to Gaza right now, despite lacking Israeli permission.

The Guardian has an 'explainer' about the India-Pakistan conflict that manages to avoid stating that the border between the countries was originally drawn by an Englishman who had never been to India and signed off on in a hurry by Lord Mountbatten because he had to get back to Britain for a party.
