In mathematics, especially in the fields of universal algebra and graph theory, a graph algebra is a way of giving a directed graph an algebraic structure. It was introduced by McNulty and Shallon, and has seen many uses in the field of universal algebra since then.

Circles and hyperbolas are, in a sense, surprisingly similar shapes. In this video, we explore the mystery behind their strange connection and step into a world of “rotation” and “angle” with meanings quite different from the usual ones. The key to this story lies in hyperbolic functions, which share many properties with trigonometric functions.

This video was really helpful in understanding the hyperbolic functions! Was happy to see that a connection I saw to spacetime is actually an application of them.

The idea of bossing you around is almost tempting enough to lure me from the beach.

The email was from Brian Price, who'd done his residency at PTMC before covid, then sailed straight into a cushy gig at Cedars thanks to family connections and Adamson's recommendation. Robby had quietly hated him, happy to see him go.

Brian's email included a forwarded job listing, seeking a temporary Chief of Emergency Medicine for PTMC, to start July 4th, Robby's last day before his sabbatical. Jack had been expecting Gloria to ask him to step up.

He'd heard nothing from her. And now this, as good as announcing the news: they were bringing in an external hire.

Dana shot him a meaningful look. “She up and says to me that Robby can’t stand to be alone, has got the TV on in his bedroom all night.”

Jack scoffed. “No, he doesn’t.”

Dana stilled, her blue eyes locking onto his. And just like that, it went from an idle comment to a moment. A moment that expanded, curling into something weighty, settling leaden in Jack’s gut. “That right?” she muttered, and there was a whole epic journey packed into those two words, going from how would you know all the way to how did I not know.

Fuck.

On todays episode our hero attempts to explain the “puppy girl” while trying to sound sane. This subculture has become quite prominent in online trans feminine spaces, so she hopes to figure out why that is. Using an excellent paper published last year, anecdotal evidence, and the occasional first-hand account, she gets to the root of what it means to fully embrace becoming a puppy. Trans voices are needed more now than ever, and some of them just so happen to bark.

We urge designers, especially designers who seek to build a world without policing and cages, to adopt a praxis of Abolitionist Design. To do so, we have three recommendations. One, designers must refuse to design policing tools and should prohibit their work from ever being used for policing’s ends. Two, designers should resist and push back against the appropriation of design methods and discourse for policing’s ends. Three, designers must develop their knowledge and discernment of policing ideologies, and in turn, of abolitionist ones. Designers should fight to abolish literal cops and the ones in their heads. Freedom demands that, and nothing less.
