NEWS --> BBC confirms to me that they did edit a line out of historian @rutgerbregman.com's speech. It called Trump "the most openly corrupt president in US history."

BBC also confirms this was done on the advice of lawyers. So Trump's threats worked.

New piece:

Trump’s Fury at BBC Gets Unnerving Results with Pro-MAGA Edit Stunner
First, British Broadcasting Corporation execs resigned after Trump complained about a segment. Now the BBC edited out a line from a historian that was critical of Trump. Where does this end?

I wish I didn’t have to share this. But the BBC has decided to censor my first Reith Lecture.

They deleted the line in which I describe Donald Trump as “the most openly corrupt president in American history.” /1

New from me for @science.org: A major planetary science conference will require submitted abstracts to comply with Trump's anti-DEI executive orders.

This conference, LPSC, is a big deal. It's been running since 1970 and is one of the biggest planetary science conferences out there. 🧪🔭

very funny to read these emails and then remember summers wondering whether the leaky pipeline in stem was because women are inherently bad at math
The emails have Summers reporting to Epstein about his attempts to date a Harvard economics student & to hit on her during a seminar she was giving.

Thanks! It was written by a former @physicsworld.bsky.social student contributor, Amy Searle, who's now hoping to break into freelance science journalism 😁

The researchers in the article seem to think it might have to do with waste. “It is likely we have to waste more information to go in one direction over the other,” says Jayne Thompson. Quantum computers wouldn't have this waste, so could this be another area for "quantum advantage"? (2/2)

A fun tidbit in this article about #quantum information and game theory. Apparently LLMs, like humans, find it harder to write stories back-to-front. That's normal for us, but weird for computers, because the two tasks ought to be informationally equivalent. (1/2) ⚛️🧪 physicsworld.com/a/playing-ga...

Also, the incumbent mayor of Overland Park, Kansas (an old-school chamber of commerce former Republican) won reelection on a platform of urban renewal and denser housing, beating a nimbyish former city councilman who was apparently a huge PITA to work with on a personal level. So that’s good, too.

The new guy is called David Benson and I recognized his name on the ballot because he was the district superintendent back when I was a high school newspaper editor covering school board meetings. He was a pretty decent guy then, too.

Good things can happen even in supposedly “red” states.

I haven’t seen it mentioned on here yet, but a school board race in my Kansas hometown ended with a book-banning, health-education-denying, trans-folk-insulting “Moms for Liberty” incumbent losing out to a career educator/former Democrat state rep, and I love that for both of them.

More of this type of AI application, please.
Google's DeepMind model (GDMI), which started releasing forecasts in June, has been utterly crushing the performance of traditional weather models.

(Of particular embarrassment, the US's most "mainstream" forecast model, the GFS (AVNI), performed *awfully* - often *double* GDMI's track error)

If we're starting another quantum hype cycle, I need people to understand that there are pretty much just two practical problems we *know* have an exponential speedup on a quantum computer. These are:

1. Breaking the internet
2. Being quantum

A few other problems have a smaller speedup, or none

If you’ve ever tried mixing oil & water, you’ll understand how the Rayleigh-Taylor instability develops. The fluids separate, forming an interface that does weird things if poked in the right way.

Turns out the same thing happens when the fluids are #quantum. 🧪⚛️

Assuming she actually exists and isn’t a figment of a scammer’s imagination, I feel sorry for Canadian Margaret Harris. But at least she chose the email of Nosy Journalist Margaret Harris rather than Criminal Hacker Margaret Harris when she was setting up her eBay account!

Yes, this seems like the best way forward – with apologies to the 62-year-old Margaret Harris in [street and number redacted] Owen Sound, Ontario, who’s unfortunately going to discover her account doesn’t exist when she tries to check on that blue button-down dress she was hoping to sell.
