I tweet on mathematical visualization, puppies, programming, and physics. They/them.

@stylewarning Those of us who cut our programming language baby teeth in the 70's laugh in TECO and APL.

@samlakig @stylewarning @isenditbacc It now embeds @SymPy which much improves symbolic integration and simplification.

[Ron Avitzur @RonAvitzur]

@stylewarning @samlakig @isenditbacc Alas, Grapher replaced my (original)  Graphing Calculator, which is now at https://t.co/U2kWZ2jQDO for macOS and https://t.co/4IQsubz7PU for iOS

What makes me sad seeing photos like this & of the NASA astronauts is, you must understand, these athletes didn’t just spontaneously all decide to mask. They’re being forced to mask bc richer ppl have a stake in their bodies & health. Their health has value. Yours doesn’t.

If governments had been honest & said, “Mild Covid leads to cancer, ALS, Alzheimer’s, diabetes, strokes/heart attacks, autoimmune disease, psychosis, stillbirths, clots, infertility, accelerated biological aging, COVAIDS, & certain premature death,” things would be different.

@hr_unhinged "Rogue operational autonomy," you say? Thank you for adding that to my lexicon! I offer https://t.co/nRG2JgLVn8 as my personal example of the genre.

[Ron Avitzur @RonAvitzur]

Karen has a point. What next? Rogue teams reviving cancelled projects outside the chain of command? Random engineers roaming in off the street trespassing and building new products in the middle of the night?Chaos!

I am utterly enamored of the phrase "rogue operational autonomy"

Yesterday I noticed the office printer was working perfectly, which raised my suspicion immediately.

I checked the logs and saw someone had cleared a paper jam at 3:12 p.m.

No ticket, no Slack, no communication.

Just silent action.

I asked the office if anyone had fixed it.

Everyone looked confused except one employee, who stared at his laptop a little too hard.

I pulled him aside afterward.

He admitted he unjammed it because “it was right there” and “took five seconds.”

I told him unilateral problem-solving disrupts our culture of collaboration and that he needed to go through the right channels if he wanted to take on a new project outside of his job description.

He said he didn’t realize fixing things was a chain-of-command issue.

I told him everything is a chain-of-command issue.

I wrote down “rogue operational autonomy” and locked the printer tray.

Wild that healthcare workers wearing masks around sick people is now considered controversial.
Protecting people isn’t politics... it’s professionalism.

@1goodtern Public health was a nice experiment for a hundred years. Here in the US where RFK Jr is destroying it
people will have to relearn why vaccines and fluoridated water and food inspectors were invented in the first place while those who study history are doomed to watch in despair.

[Joyce Carol Oates @JoyceCarolOates]

So curious that such a wealthy man never posts anything that indicates that he enjoys or is even aware of what virtually everyone appreciates— scenes from nature, pet dog or cat, praise for a movie, music, a book (but doubt that he reads); pride in a friend’s or relative’s accomplishment; condolences for someone who has died; pleasure in sports, acclaim for a favorite team; references to history. In fact he seems totally uneducated , uncultured. The poorest persons on Twitter may have access to more beauty & meaning in life than the “most wealthy person in the world.”

The five things you need to know if you're just realising that it's bad for you to keep catching Covid:

[SARS‑CoV‑2 (COVID-19) @COVID19_disease]

The study suggests that acute COVID-19, irrespective of Long COVID status, is associated with an increased risk of car crashes, likely due to neurological changes caused by SARS-CoV-2.

[SARS‑CoV‑2 (COVID-19) @COVID19_disease]

Study Finds COVID-19 Linked to 50% Increase in Car Crashes Due to Neurological Changes.

The SARS-CoV-2 pandemic raises concerns about long-term neurological effects, as Long COVID symptoms could impair driving abilities, but their specific impact on driving remains understudied.

"Minimizing COVID-19 is maximizing social harm"

"Governments, in the interest of maintaining the status quo, seem to be misleading people and hoping for the best."

SARS-CoV-2 is an ongoing threat to human health

"Last month Neil Sprackling, a CEO with Swiss Re, cited long COVID as a significant factor contributing to that two per cent jump in excess deaths, particularly in people over the age of 65."

Much better visually.

We now visualize the 3D version of our stunning Blaschke-Quotient Flow from our previous post.🤗🤩

What follows is a mesmerizing break of dawn in the some realm of complex space with zeros and poles still spinning under SU(1,1) Möbius symmetries on the Poincaré disk…but phase is now shaded by the Fubini-Study metric. 🤯🤯🤯
