My maths-and-football project is back for the 2026-27 season. The league tables at alt3.uk are mathematically adjusted to show how well each club has actually done in the current season, taking info account (in a mathematically coherent way) the standings of opponents already played.

Full explanation of the maths is on the website, along with the current league tables (for now it's just Premier League and EFL Championship; the other 6 leagues in Europe that are normally covered will be updated for this season quite soon).

I know this isn't terrorism. You know this isn't terrorism. The authorities know this isn't terrorism. But, once again, they have labelled protesters "terrorists", as part of the long-running programme to ensure that no one dares protest about anything any more. www.theguardian.com/uk-news/2026...

So often what are called “culture wars” are one set of people saying “please can we live without perpetual persecution” and another saying “no, f*** you” but the press considering the latter group have “legitimate concerns” and must be perpetually platformed

These ratio outcome variables are a plague in the sciences. If your analysis treats 1/2 and 10/20 as the same evidence, then you have discarded uncertainty in the outcome. Model what you measure, not what you construct. Use the denominator as an exposure instead.

The study is based on the CD index, a citation-based measure of how much the successors of a work still rely on its predecessors, running from -1 (consolidating) to +1 (disruptive). Key detail: a paper with zero references automatically gets CD = +1 as soon as it is cited once.

There's lots of stuff LLMs can't do, but if you want to disbelieve all the recent math, you have to believe a bunch of Fields Medalists with long track records are just straightforwardly lying about the thing they care most about.

"Impact as pressure, rather than recognition" chimes with my experience. In UK, the REF requirement to document impact makes extra work not properly recognised by colleagues or institution, and not portable. A sane UK academic should avoid having impact. Perverse. blogs.lse.ac.uk/impactofsoci...

blogs.lse.ac.ukAre high impact researchers less happy? - LSE ImpactImpact agendas are framed as ways of highlighting & rewarding work that reaches beyond academia, but do they come at a cost to researcher happiness & wellbeing?

Exactly this. Starmer and Reeves ended the destructive misrule that had characterised the previous 14 years, but they were elected to change politics and the economy rather than stabilise it in a bad place.

Zia Yusuf claims Farage is bravely "bringing forward" the judgment of "the ultimate authority": the people of Clacton. Two problems here: 1) He's insisting they judge *before* the full evidence has been heard, not *after*; 2) No constituency can exempt its MP from rules designed to protect us all

One of the lessons of the last two years is that Labour urgently needs to stop being afraid of its own shadow. Burnham should appoint whoever he thinks would be the best Chancellor and throw his authority behind them. The Daily Mail will try to kill them anyway. So just govern.

Tim Bale@timbale.bsky.social

Hard not to regard this as a classic example of a pre-emptive campaign by certain sectors, along with their media sympathisers, to discourage a new prime minister from appointing someone who might damage their interests in the long and short term. And it will almost certainly work.

It's just one long stream of BS from these fossil fuel-backed clowns. Adopting their policies would destroy a million jobs (see next post) while creating almost none in return. Total environmental and social vandalism. The absolute state of "conservatism". www.theguardian.com/politics/202...

The UK Statistics Authority has written to Kemi Badenoch today, following our fact check of her inaccurate claim that the total welfare bill is now higher than income tax receipts “for the first time ever”. We hope she will correct the record soon.

It’s the utter shamelessness that is so striking If not those leading Leave then who should have plans? He can’t blame the utter mess of the Brexit HE delivered on anyone else That was HIS plan. A terrible one Helped along by political weakness & knee-jerk voting And we are all paying the price.

10 years ago, after narrowly winning the referendum, Boris Johnson confessed, "We didn't have a plan for what to do next" "We didn't think it was our job to have a plan" 10 years later, Brexit continues to be a disaster

Makerfield is - of course - hugely important, and perhaps Nigel Farage may be encouraged to fade away & spend more time with his £5 million "personal security" £££ & other donations - but today's biggest news is this: the real cost of Brexit to all of us. www.bbc.co.uk/news/article...

Reform have now lost six by-elections in a row in England, Scotland and Wales. Their national poll rating is 26% – below Labour in 1983 – and Farage’s approval rating is -37. They’re very far from the voice of the people and need to stop being treated as such.
