Great fun to attend the @mpinb.mpg.de Open Day today. Amazing to see their work connecting vision to brain activity in mice, fish, & hawks and in mapping the brain “wiring diagram”. I have a touch of building envy too!

I do like the way you walk in to Bonn Center and randomly find a huge wine festival in the Church platz. There’s a lot to like about this town.

Bonn has a plaque on the site of its Nazi era book burning. Hemingway, Marx, Sinclair, Brecht. Lots of familiar names.

The new Ray Dolby Center for the Cavendish Laboratory is a most un-Physics like building. Where’s the decaying concrete?

Great #SKAO2025 conference summary from McClure-Griffiths. Ups: Community! Real SKA image/dishes! So much SKA Precursor science! Downs: Timeline, especially for MID. Lessons: Pretty public images matter, data is difficult, telescopes are always delayed.
