And good luck to anyone trying to lecture in this disaster of a room. Why is it that academic architecture seems to be designed to actively impede academics?
And image of a ridiculous lecture theater - open top so sounds travel, circular so there's no way to focus on a board, flat with terrible looking uncomfortable chiars, pillars in the middle of the room. Effectively a designed torture chamber for anyone unlucky enough to teach in it.

It's a constant battle in the Guardian for who can make me want to donate less.

Everything going according to plan for Starmer...
Two headlines next to each other. First reads "Wes Streeting prepares to lauch leadership challenge against Keir Starmer" from 4h ago. The second "Starmer has 'full confidence' in Streeting despite health secretary's allies saying he is planning to resign - as it happened" from 6h ago.

Penrose already nicked that one for twistors - arxiv.org/abs/hep-th/0...
PDF in which we read 

"We want to understand the − − − + + amplitudes in
the “original” twistor space with homogeneous coordinates λ, µ. In the language of twistor
theorists, we want to understand the “googly” description of the − − − + + amplitudes.
(The term is borrowed from cricket and refers to a ball thrown with the opposite of the
natural spin.)"

My institution insists on using Microsoft products. Within Microsoft Teams, there is a tab labelled "Teams". Within that tab, I have two sets of "Teams", one labelled "Classes" and the other "Teams". So to locate a particular discussion, I have to open Teams, go to Teams and expand Teams.
Image showing MS Teams, and within that the tab Teams, and within that the option of Teams...

Not a great sign that your metascience project will be able to access expert assessment when you match me to a research area nowhere near my own, based on a paper I didn't write.
Email text reading: "To David Sloan,

The UK government's Metascience Unit and the University of Sussex are keen to receive your expert assessments on the novelty of selected publications within your expertise.

We have matched your work (Exploring pedagogical culture for accessibility education in computing science. (DOI: 10.1145/2899475.2899490)) as relevant to at least one publication in our project, which we would like you to assess."

28th hour of the meeting. I imagine at this point someone has a question, or "..really more of a comment than a question"

Ok, now LinkedIn is joining in gaslighting me that I have a medical background. Is this because I started watching Scrubs again recently?
LinkedIn Message reading " Outlier:

We loved your Medical background David.


But we were wondering - are you interested in joining a new research platform where you can earn an income by finding issues in the world's best AI models? Outlier is owned by Scale AI, who have received a major investment from Amazon and Meta."

First *they* came for the pronouns. Then *they* came for the adverbs...
Post by Reform UK's Steve Miller, reads "Do YOU support @reformparty_uk to end Woke nonsense!? I do. Start by banning pronouns in the public sector."

I don't think you could sum up the Guardian better. Columnists that couldn't find their left hand given two tries.
Two article headlines, the first "It's the anti net-zero, anti-woke Tony Blair - how was this man ever considered a progressive?" By Zoe Williams. The second "Stop calling Tony Blair a war criminal. The left should be proud of his record" by Zoe Williams. The second goes on to say in subtitle "From Northern Ireland to the NHS, Blair left a real progressive blueprint. But the left has allowed it to be obliterated by Iraq".

LinkedIn "messages" (adverts) have really streamlined their processes.
Text reading "Sound like something you'd be interested in? Click the link below to start your trial today. And with ongoing pricing from just £8 per moth, we're levelling the playing firled for small businesses." Beyond the text there is simply a button labelled "Not Interested".

Yes Outlook, that's exactly the formatting you should be automatically applying. AI isn't going to kill me, but it might make me lose my will to live.

I'm hugely in favour of interdisciplinary work, but I think even for me the journal would be a stretch...
