The audiobook version is read by the author which is great news because IMO she's got the *best* voice (if you've ever heard voiceover on a Whittakers chocolate advert you've heard Elisabeth Easther's warm dulcet tones)

My little sister Elisabeth Easther has the #1 best selling book in New Zealand's indie book stores this week. Proud as a cat with two tails -- and also on behalf of our Mum and Dad who are not here to see this, but would have been fully chuffed.

BTW, this Auckland paper is a global collaboration. Zagorac, now at McGill, has a Yale PhD with me as an external supervisor; Wang, now at Gottingen, has an Auckland PhD. And Zhang – who did the key calculation – is an ANU undergrad who started this work on a semester at @aucklanduni.bsky.social .

Paper day: Stone Skipping Black Holes in Ultralight Dark Matter Solitons with Luna Zagorac @cosmolooney.bsky.social Frank Wang and Alan Zhang 🔭🧪

This is a lovely piece of work and some subtle physics relating to a fascinating model of dark matter arxiv.org/abs/2602.11512
Stone Skipping Black Holes in Ultralight Dark Matter Solitons
The orbit of a black hole moving within an ultralight dark matter (ULDM) soliton is naively expected to decay due to dynamical friction. However, single black holes can undergo ``stone skipping'', wit...

Apparently we're getting an "English Language Bill" to make English an offical language of Aotearoa -- the odd thing is that this key document already seems to be written in English.

Inception, but for lawyers.

Going out on Valentine's can be hectic so instead ate at home this year. For starters, Julia Child's french onion soup, followed by steak au poivre, Robuchon's mashed potato recipe, and a nice fresh summery salad.

Just realised that FOZZIE and FONZIE differ by a single letter. Did it when I nearly fat-fingered my way to losing my GIF-game, but pulled it back before disaster struck.

Just asked for a conflict of interest statement. Was tempted to reply

"Nae king! Nae quin! Nae laird! Nae master! We willna' be fooled again!” but settled for "None".

Sigh. Grown-upping is hard sometimes.

My closing thought: “Any scientist taking $29m in taxpayers’ money and concealing major project problems would find themselves in very deep trouble. But with MBIE we have not seen anything near a serious investigation, just a report that dodges the issues.” 9/9
