Pleased to see this. The current system regressively, hideously entrenches generational financial advantage. I have an academically brilliant friend from a single-parent family, and she has a HUNDRED THOUSAND POUNDS of student loan debt. But rich kids start life with their debt paid by parents.

I'm constantly trying (/failing) to get this point across.

If you're a trained expert in a field, then it may be worthwhile to question the scientific consensus of your peers.

If you're not, the scientific consensus is absolutely the best you can do and it's arbitrary foolishness to disregard it.

Very well referenced & well argued summary of where we are on the latest STFC funding crisis. I'd only add two more: George Efstathiou's analysis of STFC's governance problems telescoper.blog/2026/02/06/t... and @ersatzben.com's forensic analysis of the 'buckets' πŸ”­πŸ§ͺ www.ersatzben.com/p/the-bucket...

It never ceases to confound me just how many folks think the point of essays is to provide teachers with essays. That teachers just like, collect them, or need them for sustenance or something. Rather than the point of them being the *actual fucking act of learning how to think about shit*

Unpopular opinion: the outcome appears to be good. Badenoch undertook on air to review the student loans policy with Martin Lewis. If this happens, Labour will need to raise their game too. And about time. Student loans are a catastrophic policy scandal. Well done to Martin Lewis for his initiative

β€˜Don’t go to the US – not with Trump in charge’: the UK tourist with a valid visa detained by ICE for six weeks Karen Newton was in America on the trip of a lifetime when she was shackled, transported and held for weeks on end.

Totally appalling way to treat anyone but in this case this woman had not broken any immigration rule at all. And the British consulate were completely and inexcusably useless. Awful and I think deserves some response from the Foreign Office.

Meanwhile, here's the terribly boring ceiling in the room next to where the ELSA meeting is happening. Why are university rooms and buildings always so dull dull dull?

The Bucket Stops Here UKRI’s new funding framework takes a stab at classifying budgets – but doesn’t yet govern research

Bucket theory is unglamorous but very important. @ersatzben.com is forensic here - a must read for those interested in UK research policy

That old saw about how "good times make weak men" is true in the sense that stable times with material abundance create reactionaries who want to destroy the systems that protect them because they're too sheltered and stupid to understand that things can get meaningfully worse.

True decadence looks like people who are three generations removed from the cultural memory of polio refusing to vaccinate their children against deadly communicable diseases because they don't like needles and don't think there will be any consequences, not queer

So much of our present crisis is coddled, ignorant, and short sighted people tearing down the institutions that protect them because they don’t understand that bad things can happen.

The RAS was saddened to hear of the passing of our former President, Professor Mike Cruise, who has died aged 78.

"Kind, thoughtful and honourable", Mike was a "stalwart of the RAS". Our thoughts are with his family, friends and all who had the privilege to know him.

Threatening to cut funding to someone because they disagree is a *real* threat to academic freedom of the kind frequently seen under fascist and authoritarian regimes.

This is also confected bullshit. There is no obligation whatsoever for a society or institution to invite a speaker.

10.02.2026 11:01 β€” πŸ‘ 146    πŸ” 51    πŸ’¬ 5    πŸ“Œ 0

The law on universities and free speech prevents speakers from being *disinvited after they have been invited*. It does not require universities to provide a platform to whoever demands one.

Let's not mince words: the threat to cut funding to every university who disagrees with them is fascist.

Oh weird. Acoustic or electric? And if acoustic, classical or metal strings? I wonder if some spectrogram software might’ve shown up the anomaly. Though what you’d do with that diagnosis, I’ve no idea. I expect acoustic stringed instruments vibrate & resonate in all kinds of weird ways

…it sounded weirdly dull. His experimenting showed you need the dissonant harmonics. Oh and another time he made a classical guitar (he also loved woodwork) & pushed the boundary of a lightweight structure. It sounded wonderful. Until one day there was an almighty BANG and it imploded.

Actually with your techy background you might enjoy another story about him. Armed with one of those old oscilloscopes with a green CRT trace, he discovered a grand piano had some dissonant high frequency harmonics. He dismantled the piano, damped the harmonics on the soundboard, and…
