Both popular science articles and many textbooks describe the Casimir effect — an attractive force between two closely spaced neutral conductors — as being due to the exclusion of some of the zero-point modes of the electromagnetic field, whose wavelengths are greater than the separation between the plates. In this account, the vacuum between the plates has less energy than ordinary vacuum.

A formula based on this model seems to agree reasonably well with the measured result. This has encouraged people to proclaim that “vacuum energy is real” and (sometimes) to suppose that this model can be pushed much further to predict larger regions of greater negative energy.

But in fact this force can be modelled as arising between the plates in a far more conventional way, related to van der Waals forces, which makes no reference at all to “vacuum energy”, and the formula based on zero-point modes can be seen as merely approximating a more accurate formula based on the material properties of the plates.

I'm greatly enjoying the latest version of the Old Maps Online website. It has a very smooth time scrubber where you can see political borders change through time, and then browse georeferenced historical maps from map libraries like the David Rumsey collection.

https://www.oldmapsonline.org/

And just the interactive map without the historical scans is available at TimeMap.org

Every chance I've had to interact with satellite operators in conferences, I've asked them about their plans for dealing with solar storms (I'm particularly worried about Starlink, which requires dozens of maneuvers per day to avoid collisions. What if a large fraction shuts down for a few hours?!)

The universal response to my inquiries has been "Don't worry about that, it'll be fine!"

I guess we're going to find out very soon. https://www.swpc.noaa.gov/

"Here’s where it gets interesting — GCJ-02 is based on WGS-84, but with a deliberate obfuscation algorithm applied to it. The effect of this is that there are random offsets added to both latitude and longitude, ranging from as little as 50m to as much as 500m
(...)
it’s against the law in China to convert GCJ-02 (obfuscated coordinates) into WGS-84"

In Vox, I explained how federal policy encourages car bloat, making American vehicles more enormous, polluting, and dangerous than they'd otherwise be.

That's the exact opposite of what we should be doing.

Journalism has a responsibility to say when something just isn’t true, and it’s hard to argue against accurately and empathetically portraying the struggles of people long excluded. But objectivity means many other things besides “both sides” and “white and male” — it covered a range of virtues that still ring true.

Helsingin Sanomat kirjoitti tänään kiinnostavasti siitä, miten kaavoitus ylläpitää S- ja K-ryhmien duopolia, ja nostaa sitä kautta ruuan hintaa Suomessa. Mutta mikä itse asiassa on kaupan keskittyneisyyden suhde ruuan hintaan? 1/10

Visualisointi päivittäistavarakaupan keskittyneisyydestä ja kotitalouksien elintarvikkeisiin käyttämän rahamäärän kehityksestä suhteessa koko kulutusmenoihin. Vuosina 1985–2001 kahden suurimman kaupparyhmän yhteenlaskettu markkinaosuus pysyi vakaana ja ruuan osuus kulutusmenoista laski. Vuoden 2001 jälkeen kahden suurimman markkinaosuus on kasvanut ja ruuan osuus kulutusmenoista pysynyt melko vakaana. Vuoden 2012 jälkeen ruokaan käytetty osuus kääntyi jälleen laskuun, mutta vuonna 2022 se nousi voimakkaasti. Muutos selittyy kuitenkin osin Tilastokeskuksen kulutustutkimuksen uudistetulla laskentamentelmällä.

There are many sites offering free, print-ready CC0/public domain illustrations, photographs & vector graphics. Eg, Pixabay offers 4.4 million images, Unsplash 3 million.
Many fonts are also free for commercial use. And you can put the design together in free Open Source software.
With so many free images/fonts available, it's easy to create multiple design concepts for your book/product). And it's all done with the consent of the artists/photographers/typographers.
There's no excuse.

I thought I had figured out a clever way to automatically add alt texts to images for InDesign using and the 'ImageDescription' field, but then I learned that said field is ASCII only.

The XMP data could support unicode, but working with that is apparently a total pain.

jhilden,
@jhilden@vis.social avatar

YES solved it.

If you need to programmatically add alt texts to image metadata with non ASCII letters for use in e.g. , use Exiftool. It works like a charm! https://exiftool.org/exiftool_pod.html

Simple as:
exiftool -s -AltTextAccessibility='Pig saysBröther give me some öats' edited-exif-ps.tif
Your alt text is now readable in as From XMP:Alt Text (Accessibilty) under Object Export Options in InDesign.

I'm trying to pay my Virginia income taxes online, and they have disabled paste in any field of consequence. Paste in a password? Nope. Your bank's routing number? You're gonna have to hand-key that. Your bank account number? You better believe you're typing that in.

If you wanted to force people to create crappy passwords and cause them to accidentally siphon money out of strangers' bank accounts, this is how you'd do it. And somebody went to extra effort to make it be like this!

People are buying this stock not as a solid investment but as a symbol of allegiance, which is cult thinking. The stock is massively overvalued and these small retail investors are going to end up taking a bath that they can't afford to take. They're going to lose their retirements, all for a man who would loathe them individually and to whom their only value is the money they can give them. They're not even being (actively) defrauded. They're doing it to themselves.
