#ITeachPhysics another relative velocity video for you

They’ll never be *good* at the third law, but this helps an enormous amount! 😀

Cannonically, I think.

On the feeler, by the dealer. I gotta try that phrase! 😀

Demand that students write descriptions of forces. This method *works*. A person pushes a block to the right. After the person pushes, the block slows down due to friction on a rough track. Draw a free body diagram of the block after the person pushes while the block s…

Here's an example of how my insistence that students list the applying and experiencing object for each force in a free body helped a student get a free body just right. #iTeachPhysics

Watching men's figure skating. Currently in 1st place: Canadian skater Gogolev. Wonder if Gogolev is friends with Disco Stu.

This is about soccer, but has direct resonance for when physics teachers have to do public relations with folks - parents and colleagues and admins - who don’t know about physics teaching but think they do, and yet have a right to give their input. #iTeachPhysics

Birnam Wood do come to Dunsinane

Amazon Ring: Now You Can Stalk Anyone!

That review just gave Seattle a timeout. Oy. Just go with the call on the field.

And shit, there's the first crypto ad. See, the Federal Reserve doesn't need to advertise at all, let alone at the Super Bowl.

Mercury, Messenger of the Gods, by Giovanni Battista Tiepolo, 18th c, 📸 by @PhilEllsworth1

Lots of AI baloney. Saw one ad for Draftkings before the game, none during yet. And no crypto so far, thank gawd.

The PSA condemning anti-Semitism loses a touch of its impact when followed by a chorus of toilets singing Phil Collins.

Kenneth Walker III (Seahawks RB) looks like he's a 40yo English Literature professor.

That Patriots pass defensed looked like the Donnarumma save from this afternoon. @meninblazers.bsky.social

At Levi's Stadium, that spread costs $1349 plus tip.

Huh. Super Bowl ad for AI. So, people need to be convinced, at great expense, to use their crappy product. Sorta like pepsi.

Would they say the Super Bowl is in the Chicagoland Area if it were held in Milwaukee? Cause San Jose is pretty far from the GG bridge...

Let’s just make the whole team a captain now?

Only on VERY special occasions. 😀

But these are the same folks who think Born in the USA is a super patriotic rah rah America Lee Greenwood-style tune.

Why are these hall of famers getting serenaded by violins as they leave the port-a-john?

Me! I'm a many who wanted an AI-free browser experience!

I have yet to see any evidence that there is a market for AI-generated books outside of people being tricked into thinking they are not AI-generated books. AKA, it is a project of scamming and deceiving people, and really should be treated as fraud

Just finished watching Liverpool/Manchester City. Gawd, I hate 115-charges-Manchester City. They earned the win tonight. The save at the end was not world class, but universe class.

YouTube video by Bruce Springsteen Bruce Springsteen - Streets Of Minneapolis (Official Audio)

I wrote this song on Saturday, recorded it yesterday and released it to you today in response to the state terror being visited on the city of Minneapolis. It’s dedicated to the people of Minneapolis, our innocent immigrant neighbors and in memory of Alex Pretti and Renee Good.

Stay free

Very interesting! I mean, could also be selection bias - those who become musicians are those more likely to pay attention to detail. But whatever the reason, I’ve observed similar. Quite cool.
