Abandoned apple fritter or bear claw clinging to existence on the NE 21st Ave I-84 overpass for any who wish to partake. Took a bite. Delicious.

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...

have fun with this one

im struggling with my upper-highschool-levels of maths knowledge, i dont think theres any way i can merge infinite integrals so im looking for online things

dont sploit solutions, if u do put it in a pastebin #math #maths #mathsky
Sliding Average Consider a function f(x) that is equal to 1 in the interval x ∈ [-1; 1] and 0 elsewhere: Now define a new function g(x). g(x) goes over the entire real line of f(x) in a sliding window of width 1 and, at each point of f(x), takes the average of all values in that sliding window, creating a new graph. On first iteration of g(x) this graph is an even-sided trapezoid: Now repeat this process: let f(x) = g(x) and continue taking the sliding window average an infinite amount of times. Which function h(x) best describes the final function f(x) after n iterations of g(x) as n approaches infinity?

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:

Other than minor presentational tweaks, I also added a pretty color gradient for the charge density in the "floating" Hall polarization case. #ITeachPhysics
Screenshot of a physics simulation constructed in Desmos. It shows a metal bar sliding along rails in a magnetic field. Various controls, values, and arrows are also visible.

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)

Bari Weiss lied in her memo. She said segment didn't report administration's legal justification (it does in the very first sentence) and didn't say how many detainees had been charged with crimes as opposed to just those who were convicted (it does). www.muellershewrote.com/p/watch-the-...

The "Big Dipper in 3D" installation in our "Astronomy for Everybody" exhibition started out as a toothpick-and-plasticine mock-up on a cardboard. :-) 🔭🎢
Yellow plasticine "stars" on toothpicks and plasticine bases on a cardboard. From the perspective of the photograph, they form the "Big Dipper".

In #MathsToday we did one of my favorite activities: Regression by Hand.

Our goal is to model the bounce height h_bounce of a bouncy ball dropped from height h_drop.

#mtbos #ITeachMath
How high does a bouncy ball bounce? A table shows columns h_drop and h_bounce. An image depicts four students next to a whiteboard. One holds a meter stick and another has dropped a bouncy ball. One looks on as another takes a video.

Grades are in, so I've been playing in Desmos. Here's a dynamic transformation of a popular hexagon dissection into a rectangle. I've included parameters to control the shapes in the dissection. Can you make a square?

This is fucking grim. Somebody invented a white guy, an "IT professional" named Edward Crabtree, who stopped the Bondi shooting and spread it all over the internet, which was picked up by AI agents and slop aggregation sites.

The real hero is a fruit stand owner named Ahmed el Ahmed.
A wrong Grok post making up a white guy who stopped the Australian mass shooting. BBC 'Hero' who wrestled gun from Bondi shooter named as Ahmed al Ahmed Emily Atkinson Sun, December 14, 2025 at 1:06 p.m. CST 2 min read A "hero" bystander who was filmed wrestling a gun from one of the Bondi Beach attackers has been named as 43-year-old Ahmed al Ahmed. Video verified by the BBC showed Mr Ahmed run at the gunman and seize his weapon, before turning the gun round on him, forcing his retreat. Mr Ahmed, a fruit shop owner and father of two, remains in hospital, where he has undergone surgery for bullet wounds to his arm and hand, his family told 7News Australia.

trumpcard.gov is live and the million dollar fees are all referred to as “gifts” or “contributions” to an undisclosed party lol
Special Benetits. For Individuals For Business Trump Gold Card For a $15,000 DHS processing fee* and, after background approval, a contribution of $1 million, receive U.S. residency in record time with the Trump Gold Card. *Additional small fees to the U.S. Department of State may apply depending on the applicant. Trump Platinum Card Coming Soon* An official website of the United States government Apply Now 个 Corporate Gold Card? The Trump Corporate Gold Card is issued to a corporate sponsor for one or more of the sponsor's employees. To apply, the corporate sponsor must pay a nonrefundable, $15,000 DHS processing fee per employee. Corporate sponsors may apply for multiple employees at once. A $2 million per employee gift upon completion of the employee's vetting is evidence that the employee will substantially benefit the United States. The advantage of the Trump Corporate Gold Card is that corporate sponsors may cease sponsoring one employee and use the gift contribution tied to the prior application as a basis for sponsoring a new employee, without a new $2 million gift. The Trump Corporate Gold Card is subject to a small, 1% annual maintenance fee and a 5% transfer fee, which includes the cost of a new DHS background check. Small additional fees to the U.S. Department of State may also apply depending on each employees circumstances.
