Mac Lane's strictification for bicategories is part of the backbone of modern algebra. In the 90s-00s, it was generalised in a couple ways to dim 3. For many years it has been one of my “north stars” to prove a version in all higher dim. Proud to announce one, joint w/ Chanavat:

In related news… I’m building out a tiger team to pursue this mission with me! 🦸 I’m looking for people who are mission-driven, technically deep, and comfortable moving between formal methods, programming languages, AI, AI safety, and cybersecurity.

I have been deliberately silent on social media for a while. I use all my social media platforms to promote education & make dreams come true for young minds. I rarely post anything about family or politics. This morning, Israel demolished the building I have an apartment in. It took 22 years of my work here & 20 years of my wife’s work to own this apartment. This madness has to stop.

Even a declaration of no quarter, even without action, is a war crime and has been for more than a century. So, you know, the SecDef just did a crime - often treated as a hanging or firing squad offense - on TV, presumably because he is too dumb to realize what his words mean.

Hegseth: No quarter, no mercy for our enemies. Yet some in the press just can't stop. More fake news from CNN reports that the Trump administration underestimated the Iran war's impact on the strait of hormuz. The sooner David Ellison takes over that network, the better.

New polling in Italy shows 69.5% of Italians believe Italy should follow Spain’s lead and deny the use of U.S. military bases on its territory. Only 15.9% disagree. A major signal of growing friction within NATO’s southern public sentiment.

Congratulations brilliant, brave, fearless @owenjonesjourno ! A major moment for press freedom in UK. @BBCNews should be deeply ashamed of its coverage of the Gaza Genocide & for appointing a man with a framed fan letter from Netanyahu on his wall to control its Mid East news
Owen Jones@owenjonesjourno

I am delighted that the High Court has ruled in my favour on the key issues in the libel case brought by Raffi Berg. The court rejected the claimant’s interpretation of the article and ruled that it expressed an opinion based on stated material. I stand by my journalism and, if Mr Berg decides to continue the libel claim, I look forward to defending my article in court. I would like to thank my legal team at @RPCLegal, my barrister Aidan Eardley KC, and @DropSiteNews, which published the article and has stood by my journalism throughout.

Today in Estonian news: - commemorations of the bombing of Nazi-occupied Tallinn on March 9, 1944, "the darkest day in the city's history"; - the parliament's foreign affairs committee expressing its support for the bombing of Tehran

speaking as glibly as Beavis & Butthead. does T***p even grasp the profound significance of what he has set in motion in the Middle East? this person whose most essential self is riding in a golf cart fatly, cheating at the profoundly insignificant game of leisure golf when he assumes no one is looking.

Pres Trump told me tonight the US had identified possible candidates to take over Iran, but they were killed in the initial attack. "The attack was so successful it knocked out most of the candidates," Trump told me. "It's not going to be anybody that we were thinking of because they are all dead. Second or third place is dead."

Today’s military strikes on Iran — carried out by the United States and Israel — mark a catastrophic escalation in an illegal war of aggression. Bombing cities. Killing civilians. Opening a new theater of war.  Americans do not want this. They do not want another war in pursuit of regime change. They want relief from the affordability crisis. They want peace. I am focused on making sure that every New Yorker is safe. I have been in contact with our Police Commissioner and emergency management officials. We are taking proactive steps, including increasing coordination across agencies and enhancing patrols of sensitive locations out of an abundance of caution. Additionally, I want to speak directly to Iranian New Yorkers: you are part of the fabric of this city — you are our neighbors, small business owners, students, artists, workers, and community leaders. You will be safe here.

Contrast this clear and morally unambiguous statement from the UK's chair of the House of Commons Foreign Affairs committee, to the statements from the EU's Ursula VDL and Kaja Kallas.
Emily Thornberry@EmilyThornberry

I am pleased to see the UK is not involved in these strikes on Iran. They are ill-advised and illegal. We will be hit by the consequences though & need to prepare for chaos in the region, with shipping lanes, oil facilities & military bases (including our own) being attacked.

The internal Democratic Party report on Harris's loss, which they concealed from the public, concluded that support for the Gaza genocide was a major factor in her loss. She gave up her chance to be president in order to make sure the killing continued. Unbelievably depraved.

BREAKING: WE WON. The High Court ruled the Palestine Action ban is unlawful as it is disproportionate to free speech and the Home Secretary breached her own policy. The court ordered the ban be quashed. Details of lifting the ban will be decided and completed at a later date.
