It hits different in Vienna

Four trees by Schiele, a landscape with layers of yellow and blue clouds lazily compressing a red sunset and little blue mountains. Four small trees with red drop-shaped leaves stand in the foreground on an undulating green ground, one is bare, two of them have their trunk split through the middle so you can see part of the background through.

A meme with a poorly drawn outline of the US depicted as a grinning face, surrounded by a cycle with four steps

There is a global resource shortage

[Insert autocracy and/or geopolitical US opponent]
has large quantities of the resource

"US hegemony is finished"

"A random farmer in bumfuck nowhere middle America stumbles across the largest supply of said resource known to man"

Sorry, last one. 🚀 🌌

A four panel (square) reaction image where Peter Parker (as played by Tobey Maguire) puts on his glasses in two panels on the left, and picture on the right becomes clear. Top right is the SPCX ticker going down. Bottom right is the CMB TT spectrum plotted in log scale: the two curves look similar with a bump at the beginning and a series of wiggles trending downwards afterwards. If you have questions about the physics of the curve or the CMB please don't hesitate to ask!

Alexandre Adler@bachpropagate· 16d

Yeah in log scale it's clearly Dl^(TT). Call the econophysicists!

The CMB TT power spectrum plotted in log scale looks a lot like the SPCX candlestick graph over the past month lol

Hey wait a minute. 🔭

Every day we stray farther from God (who isn't a cyclist, otherwise he would have mentioned it at least a thousand times)

The image generator attempts a render of a person on a bicycle. it goes poorly (legs look like tentacles, head replaced by dark brown mass of what appears to be hair).

It’s my first time visiting Toronto and I am very pleasantly surprised. Very lively and livable city. At least in perfect July weather.

The Toronto skyline seen at sunset from a small beach. Skyscrapers and a pointy spire (the CN tower) are silhouetted on a blue to orange sky. The water is a metallic blue: there are a rock and a fallen tree trunk near the bottom of the foreground.

Yeah how is that second parenthetical going for Deutschland?

An open pit brown coal mine, seen from the air, slashes through the German countryside. There are ironically wind turbines in the distance.

Energy generation capacity graph in Germany from 2002-2025. While solar and wind capacity increased a lot, 23GW of nuclear power got shut down while there was a partial substitution of coal for gas. Lignite could have been phased out completely if nuclear power plants had stayed online.

Which physics degree? The paperwork only says BA

At @berkeleylab.lbl.gov we got the newest fawns, 2026 models.

A very very young fawn with brown fur and white spots stands in the shade of an off-scene tree. The fawn is standing in front of some dried grass and on dead leaves. There is a round metal hand rail in front of the picture, the relative size indicated the fawn is very small

This post stuck with me for the stubbornness of the poster, I wonder if he has finally reevaluated his relationship with the Miscreant from Maine. Please don’t go searching for the guy to ask for an update though, this website has a bullying problem and I want no part in it.

Skeet from March that says:"And I've known Graham for years, and know his politics and character. He's dated some of my friends, he's worked with my wife-| have insights into him as a result that make me resent stuff I read about him from people who've never met him."

Hugh Laurie as Wooster with a speech bubble pointing at Andrew's skeet. He's a man with coiffed brown hair wearing a light grey suit and a red tie on a white shirt with a collar pin. He looks surprised or in disbelief.

It’s a lost fight, but I wish the "Jacobin crew" would use another symbol of popular sovereignty from the French Revolution than the murder machine approved for use by Louis XVI

I prefer the posters tbh

A red and white roundel on a khaki-brown-navy blue gradient background, with white start constellations drawn on the blue part and blue dotted waveforms in the khaki. At the top of the poster is written "Atoms in dienste des friedens" (Atoms for peace in German)

There are very nice places in California.

A view from far above of Yosemite valley with a few meadows and an azure-tinted river flowing through it. The valley is flanked by vertiginous rock faces, jagged peaks on the left and smooth cliffs on the right. A broken pine trunk can be seen on the right of the picture.it’s sunny and the sky is very blue

Wooster: What-ho, Jeeves Le Louvre: Watteau, 'Gilles'

An oil painting of a man standing dressed in white with a hat behind his face, a soft ruff, a large white coat and breeches, and pink ribbons fastening his shoes. He looks pensive, tired, maybe a bit melancholic. Behind him, half concealed by a sort of ditch, are other brightly dressed characters dragging a donkey forward. The background is an imagined forest.

arxiv.org/abs/2605.18938 That's a pretty cool paper! "First detection of the moving lens effect with ACT and DESI LS Comments: 20+7 pages, 6 figures, 1 exciting discovery, comments welcome" #cosmology

A projection of the sky on two hemispheric circles, with part of the sky in grayscale wisps and part in a pattern of red and white splotches on a blue background. The red splotches are roughly 2-10 degrees across.
There is a caption: "FIG. 1. Orthographic projection of |XG(n)| squared for the DESI-LS main LRG × ACT DR6 dataset (random-subtracted). Left: NGC. Right: SGC. The colored region shows |XG(n)| squared at full opacity within the survey footprint (DESI-LS ∩ ACT noise mask); the grayscale background shows the Planck 353 GHz GNILC thermal dust emission [42] at reduced opacity. XG(n) is the inverse SHT of XG ellm truncated at ell max = 2000 and smoothed with a 50′ FWHM Gaussian beam; the monopole and dipole have been removed within the footprint before squaring. RA/Dec coordinate lines are overlaid at 40◦ and 20◦ intervals, respectively."

DOGE moment

Dumb chudette "Data Republican" tweet:

In my initial run, which processed the first 60,000 rows, I did not find these awards—my hard drive overheated long before I could complete a full pass through the database. In a later run, which I referenced in another post, l did identify two such awards. That discrepancy is a matter of sampling size, not an issue with the query itself.
l'Il now attempt a full run, which should capture the awards you found.

Xi and the Chinese establishment talking to this admin about a framework developed by an American: Does the CCP believe in it or do they believe the Americans believe in it?

You said "here in Sacramento" in another reply? Could you look at that map and explain to me how all the R1 zoning (pale yellow) around the two trolley lines is actually high density?

Zoning in Sacramento. Two transit lines go through a whole lot of single family housing zoning

Ah, like Fsmith.
