(According to Libby the Los Angeles library does have 10 copies of the book, with 7 people waiting per copy. πŸ˜…)

But getting it from the library DOES support the author, the library buys more copies if there's a long waitlist!

Also I need to get SOME work done. I guess.

Luckily they are short, but now I have to waaaaaaaait for the next one because there are 70 (!) people ahead of me in the hold queue at the Los Angeles library.

How much do I empathize with a killer robot who just wants to curl up somewhere away from humans and binge watch content. 😭

Look I’m sorry I understand that there are deadlines but do YOU understand what it feels like to be 86% of the way through a Murderbot story?!

In general, the boxes of β€œrare” stuff from storage I’m going through is just old. A few things are valuable. And then there is a first edition of the β€œAnnual Register” from 1776 that just happens to have news of some little Declaration of Independence

Standing up for Science rally, Physics Girl is back, and we need to find more asteroids I’m angry about anti-science attacks, Dianna Cowern has made a new video, and a graph shows why we need to look for near-Earth asteroids

Great news! Physics Girl is making videos again!

Bad news: Attacks on science are so bad I need to talk at a rally on Saturday.

Interesting news: We need to find more near-Earth asteroids.

And it's all here!

There have been MULTIPLE early leaks of scientific discoveries via DECORATED CAKE. Scientists are good at many things, but shutting up is definitely not one of them.

Congratulations to Dr Tobias Meier (@tgmeier.bsky.social) on the publication of his paper "Mantle Convection and Nightside Volcanism on Lava World K2-141 b" featuring 12 former and current Oxoplanet members! You can read the paper here: arxiv.org/abs/2603.02408

Discovering exoplanets with machine learning Develop a machine-learned model of stellar spectra and instrumental quirks, and use it to discover exoplanets in radial velocity data.

Do you already have a Masters? Do you want to do a PhD in exoplanet radial velocity surveys with me at Macquarie University in Sydney?

Then have I got an ad for you!

Welcome to march. Your clever todo manager/system/thing is either smoking or actively on fire. There are still two months in the semester.

Is it an acronym? Did I start writing something in all caps and get distracted? Is it an autocorrect or a typo?
