I feel this. In my first book I used roughly one em dash per page. So I am a (vanishingly small) part of why "AI" uses em dashes, and humans like me and you now feel wary about using them.

Nothing says “support the troops” like kidnapping their family while also starting a pointless war.

Sam Stein tweet:

Susan Collins comes out against the War Powers resolution: "Passing this resolution now would send the wrong message to Iran and to our troops. At this juncture, providing unequivocal support to our service members is critically important, as is ongoing consultation by the Administration with Congress.”

There's no limiting condition to this bonkers logic.

All Trump has to do is bomb somewhere else and Susan Collins will say, 'Welp, we have to go along because not going along would send the wrong message.'

Utter madness. #MEpolitics

Also notable - the Maine Principals' Association has had a policy of allowing trans kids to participate in school sports since 2013, but only now Senator Collins is concerned about it? Journalists should ask her why it was fine for 12 years but is now bad.

Yes. Although I'm a physicist, so I never took analysis. Or Analysis. Power series are somehow primal. Every function (some conditions apply) is, at its heart, a power series.

Power series solutions will always have a warm spot in my heart. Something so fundamental and satisfying about them.

This is the same amount as the entire National Science Foundation's R&D spending for the entire field of *engineering* for the whole country. All of it.

“The River House Broke. We Rushed in the River.” The July 4 Texas flooding ripped our Kerr County home from its pillars, pulling us into the water and into the night. Then morning came.

This first-person account of bring swept away by the Texas floodwaters is harrowing & an incredible piece of writing.

Abducting people at work sites - meaning they have jobs.
Capturing them at court dates - meaning they're following the law.
Blocking them from accessible higher education - meaning they're striving for more.
And peddling lies about jobless, lawless, driftless.

I’d think a lot of people would find this gross, but as a Jewish person with cancer it has, let us say, a special repulsive resonance.

🧵 1/9 It could have mattered.

Nine minutes and twenty-nine seconds deprived of oxygen should have chastened the world to become allies, and not just for a summer.

A man being murdered by those who should protect and serve should have been an indelible metaphor.
