YouTube just made it so you can no longer sort your search of videos chronologically. This is so bigger, more lucrative promoted videos always remain on top of your search. No consumer wants this, but monopoly power means consumers have no alternative. Modern tech in a nutshell.

#iTeachPhysics: favorite 2D conservation of momentum problems?

“Those are pretexts…”

Earlier today, Border Patrol arrested a man in the parking lot of a gas station in St. Paul. They busted out his drivers side window, ultimately dragging him out of the car, pulled him to the ground, and dragged him into one of BP's SUVs.

‪A gift for science teachers in 🇺🇸: I wrote a 45-minute lesson plan based on MLK Jr's Nobel Prize speech in which students contrast the pace of scientific/technological progress with the pace of moral justice 🎢 underrep.com/lessons/0-ML... #iTeachPhysics

Everybody should watch this and see this woman, who has a baby in her arms and is thrust into basically a standoff, develop courage in real time.

Holy Jesus I didn't look close enough, saw the green logo quickly and thought this was The Onion and started chuckling man what have we done lol

they've got Raffi calling for regime change. something has shifted.

I know, I get that there are formatting standards, etc. etc. but there has got to be a better way of communicating results in a world where scientific publishing is primarily digital than what's happening in this paragraph...

You should be embarrassed to be a member of congress and issuing anything other than impeachment resolutions. You're in the model UN. They should give you legos and a propeller hat

so x dot com’s ai generated CSAM and they admitted it may violate US law and … i haven’t seen in anyone in power say much at all or call to stop using the platform

New from me: The storied fiddler Ashley MacIsaac wanted to play a show at a Nova Scotia First Nation. It got cancelled because Google's AI search summary incorrectly called him a sex offender. Now he's worried for his safety www.theglobeandmail.com/culture/arti...

Google AI now admits the error, but that's probably of little solace to him: "Canadian musician Ashley MacIsaac has no criminal convictions for sexual offenses; recent false claims to this effect were the result of a Google AI error that conflated his identity with another man of the same name."

Fun ⚛️-factlet: the New York New years ball is a recollection of Time Balls, which were used to give accurate time to ships for navigation! Since the speed of light is a million times faster than sound, there is much less time-delay than using a gun salute en.wikipedia.org/wiki/Time_ball

A Human on a Bicycle is Among the Most Efficient Forms of Travel in the Animal Kingdom (best aligned to upper-secondary courses like AP physics, AP bio, precalculus, stats)

Just recently, he was very funny in THE RESIDENCE, one of my favorite shows of the year. Plus THE WIRE, obviously, plus a *lot* of trips to the Law & Order universe, and on and on. A fabulous, versatile presence.

Strong work here! Also, it would be fun to run these numbers a second time, but using percentages of *disposable* income (i.e. after basic housing, food, transportation, child care, and health care needs are paid for)

Reminder that The Guardian has a financial partnership with openAI so they have a vested interest in trying to paint this shit in a positive light. You can't trust a single thing they say about it whatsoever

Thanks for sharing this document, @rweingarten.bsky.social. I read it, and I believe it's inexcusably inadequate and will not prepare teachers or schools to confront the very real dangers of the "A.i." products pushed by your partners, including OpenAI. A few thoughts for your consideration...

In 2023 I became obsessed with videos of dads in cargo shortswaiting in parking lots during Taylor Swift's Eras Tour. So when she came to town, I grabbed a camera and headed down to talk to them. I thought it'd be funny. It turned out to be something else entirely.

Here's a finalized version of my "bar in a magnetic field" motional emf / Hall effect simulation in #desmos: www.desmos.com/calculator/t... Other than minor presentational tweaks, I also added a pretty color gradient for the charge density in the "floating" Hall polarization case. #ITeachPhysics

Just want to add: Being convicted of a crime in the U.S. wouldn’t justify sending someone to a foreign gulag to be tortured, and arguably violates separation of powers since the “sentence” they are legally bound to serve is one issued by a judge, not Stephen Miller (i.e. the factoid is irrelevant)
