An immigration court dropped its case against Turkish graduate student Rumeysa Ozturk, a little less than a year after federal agents arrested her on a street near Tufts University

And yes, it's a climate policy class, so I get to put in a plug for "Powering Data"

Any and all further examples much appreciated.

Yes, I'll also show this... :)

Plus a quick clip of Andrew Tate saying how he's too smart to read...

Followed by one of Warren Buffet talking about how he reads for 5 or 6 hours a day...

So my plan for tomorrow's class:

Start with a quick clip of Jamie Dimon talking about how he reads 5 papers each morning...

While we're all watching one too many AI ads, I just finished grading 60 student essays. Hard to tell for sure, of course, but somewhere between ½ and ¾ must have been fully AI generated.

The AI check (shown to students at time of submission), and another Claude check agree.

Q: What time is kickoff?

A: The Bad Bunny concert kicks off around 8:00 or 8:30 p.m., but there will be pre-concert entertainment starting at 6:30 p.m. from one group called the “New England Patriots” and another called the “Seattle Seahawks.”

One of the more ambitious projections for Voluntary Carbon Credits I've seen of late: ~$50b by 2035, up from ~$1.5b today.

Quick sanity check: Today's size of Europe's (compliance) market alone? ~$200b.¹

California's? ~$10b.²

Hey @zohrankmamdani.bsky.social, minor request but one of these 'nudges' with outsized influence:

@nyc311.bsky.social alerts have a near daily parking reminder. 90% of New Yorkers don't need that.

Ask drivers to sign up for some special alerts only they need.

Bingo. Ich habe damals Latein gelernt. Mein 14-jähriger hätte tatsächlich auch hier (an einer öffentlichen Schule in New York) die Wahl gehabt.

Anstatt dessen lernt er jetzt Chinesisch. "Anwendbarer"? Wahrscheinlich. Aber am Ende geht's um das Lernen selbst. Jede Sprache ist "nur" Mittel zum Zweck.

Oh, and yeah natural gas can clearly do no harm. It has natural right there in the name.

The thing, of course, is that some of these people will get through the nomination process, where they'll do damage for decades to come.
I am running out of ways to convey how disconnected from reality Trump's judicial nominees are. They can't say that Trump lost the 2020 election, they won't say that the January 6 insurrection happened, they don't acknowledge any fact about anything if Trump hasn't authorized them to believe it
Trump Is Building a Federal Judiciary of Delusional, Cowardly Loyalists
Judges have to decide cases based on facts. For Trump judges, the only facts that matter are the ones that he authorizes them to believe.

"warmer homes in the winter, cooler homes in the summer, lower emissions, and real climate action that improves people’s lives — starting with the communities too often left behind."

Heat pumps FTW
Today in the Rockaways, I stood with NYCHA residents to announce a $38M investment to bring clean, reliable heat pumps to Beach 41st Street Houses.

More of this, much more.

Yes, induction, and heat pumps, and properly insulated windows should be standard fare for any high-end home design
