I have never been more disappointed by a spelling error:

So at a linux (or equivalent) terminal, type this:

$ telnet mapscii.me

Get an interactive world map. In your terminal.

Zoom in and out with A and Z, use the arrow keys to move.

Astonishing.

Many yearn for the "good old days" of the web. We could have those good old days back — or something even better — and if anything, it would be easier now than it ever was.

A better view of the wild solar prominences during Monday's eclipse.

We didn't break the message with this, but hey, we could have!

What it’s like to experience totality.

The Verge article on the best printer in 2024 is just completely brilliant in so many ways.

And also kinda sad.

"I’m fond of effective altruists. When you meet one, ask them how many people they’ve killed."

- Stanford professor Leif Wenar pens a devastating takedown of #EffectiveAltruism for WIRED magazine, in the wake of #crypto fraudster Sam Bankman-Fried's sentencing.

A new (diamond open access) journal devoted to #FormalMathematics has just launched: "Annals of Formalized Mathematics", https://afm.episciences.org/ . (I am not directly involved with the journal, though I am on the #mathematics "epi-committee" of the broader #episciences platform, https://www.episciences.org/ . There has traditionally not been a natural forum for publishing research-level work on formalizing mathematics, and hopefully this journal will be successful in providing one.

Reminder to @ieeevis full paper authors, the *abstract deadline* is TOMORROW (Thursday) -- you can't submit a paper without first submitting an abstract!

Michel Talagrand wins the #AbelPrize 2024 "For his groundbreaking contributions to probability theory and functional analysis, with outstanding applications in mathematical physics and statistics." https://abelprize.no/abel-prize-laureates/2024

Just now I was writing tests and for one of the properties I thought “wow, there's really no good way to test this, I guess I'll just skip it.”

I thought a little more and came up with a crappy way to test it and thought “This crappy test will be false-negative too much of the time, it probably is not even worth writing.”

Then I wrote the poor test anyway.

Then the poor test failed and revealed that my code had a bug.

@waldoj first known case of pea-hacking

@circumeo @webology there's a term for that! It's Gell-Mann Amnesia https://en.m.wiktionary.org/wiki/Gell-Mann_Amnesia_effect

#PhysicsFactlet
A quantum simple pendulum.
The pendulum position is spread out, with opacity here being proportional to the probability that the pendulum is at that position at a given time. The average position of the quantum dynamics is the same as the classical pendulum dynamics (Ehrenfest theorem).

Technicalities: I used the Crank-Nicholson method to evolve the system in time. This is a 1D problem, and the only variable I considered was the angle, with the initial state being a Gaussian.
