"I have more fun with my community on X"
The mitchell and webb sketch with the SS arguing if the skulls meant they were "the baddies". Mitchell is saying "I didn't say we weren't fun" after Webb remarked that pirates used a skull and were fun.

Is there something about tight margins being necessary for recounts to happen, maybe? If I were you I would change my display name... en.wikipedia.org/wiki/2024_Un...
A column with several numbers, the margins in each state for the 2024 US presidential election. None of them are within 0.5%, only one (wisconsin) is within a percent.

Also, if you generated your application with an LLM, or worse, had it come up with your research ideas, I have contempt and pity for you as a scientist. Of course, once you get the grant and I don’t that situation becomes:

Hell yeah we stan a polisci-transport nerd who supports women in the military
His favorite assignment was in 1961, when he served as naval aide to President Harry S. Truman during the Kennedy inauguration. Another of his naval career highpoints was being sworn in as a captain by his sister, Captain Joy Bright Hancock Ofstie. She was a founding member and later director of the WAVES.
Mr. Bright is also recognized as an aviation innovator by the Ohio Aviation Museum in Columbus, as one of the inventors of the US Navy inflatable airplane and for using Navy blimps to carry the large low-frequency antennae for anti-submarine warfare.
After his retirement from the Navy in 1963, he again attended Rutgers University on the GI Bill and studied for his Ph.D. in Political Science. He subsequently served as head of the Center for Transportation Studies at Rutgers' Eagleton Institute of Practical Politics until his fi-

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!

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.

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."

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.

Hmmmm saw a weird variation on the LBL logo in a Linkedin post, I really dislike how GenAI counterfeits images. Now wondering if the whole post was written by an LLM.
This is not the Lab Logo, there is a third window on the Campanille and the line art is not closed. There are seven rounded windows in the ALS. The font is not one of the standard ones, but looks like one GenAI will use.This is the logo of Berkeley Lab. The line art around the campanille, which has two windows, is closed.
