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.

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.

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...

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.

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
