The MLB Gameday online live game tracker has represented Tropicana Field as a uncanny space, simultaneously flatly underlit and dazzling, with a pink de-branded SODA billboard behind right field. I think they're playing baseball in The Backrooms.

I don't like the thing the MLB does where player statistics reset in the postseason. Like, Brice Turang is a .286 hitter in the regular season who also doesn't have a hit yet in 7 postseason at-bats against the Padres. Surely the .286 number is what a viewer (me) wants to see at a glance

In 1941, the administrator of St Pierre et Miquelon declared his loyalty to Vichy France rather than to De Gaulle and Free France. The Free French navy, defying the regional powers, snuck a small naval force over to seize it. LOOK AT HOW TIME MAGAZINE DESCRIBED THE WARSHIPS (link in alt)

I had to give a lecture via Zoom from my hotel, but I forgot to bring the iPad/Apple Pencil setup I usually use. Please enjoy the surprisingly stable iPhone document camera I improvised from things I had in my luggage.

Wikipedia says that Nancy Grace Roman, post-Ph.D. but pre-Yerkes in 1949, spent two months at CWRU's Warner and Swasey Observatory (then at its East Cleveland site, now in ruins, whose telescope is now at Kitt Peak and still operable.) Can't find any other info, anyone know what she did there? 🔭

I'm reading a trashy Icelandic crime novel. It features many flashbacks to characters' childhoods, including this spectacular scene where Tinna solves a math problem correctly:
"Tinna narrowed her eyes and considered the question on the board.  The teacher sighed and was about to turn back to it when Tinna said: 'The lowest common denominator of one thousand and fifty is forty-three.'   

The teacher glanced at the board, then back at Tinna.

'I'm right,' Tinna said. 'Just check it.'

In this sci-fi-guided era, surely we want guidance from L Frank Baum's TikTok, the mechanical man "fit-ted with Smith & Tinker's Improved Combination Steel Brains", one of the first thinking machines in American literature. L. Frank Baum, what does Tik-Tok have to say about AI liability?
illustration (by John R Neill) from "Ozma of Oz" (1907), of Dorothy sitting under a tree discoursing with a round-bodied, mustachioed copper automaton. Text (styled to represent halting robotic speech) reads: "I was mistaken," remarked Tiktok.  "My thoughts are usually correct, but it is Smith & Tinker's fault if they sometimes go wrong or do not work properly."

Final point is: there's no point thinking about blue-sky 0vbb detector ideas unless you're prepared to talk about beyond-ton-scale. Gas TPCs scale up surprisingly easily, and---with some assumptions about what your design constraints are---the gases proposed here can outperform xenon. 16/

is actually easier with this sort of dilution; electron tracks in xenon look like spaghetti and in electron tracks in things like BEBMO look nearly straight. Coauthor Ivana Moya produced Figure 2 to illustrate this effect and we propose a (new, AFAICT) tangling measure to quantify it. 15/

"But Ben," you're complaining, "isn't methaneselenol toxic, flammable, and one of the smelliest chemicals ever invented?". Yes, yes, and yes. That's why this is a theory paper without data on these gases: we're not touching them until our glovebox (Fig 1a) is commissioned. 8/

Using the quantum chemistry simulation code ORCA, we asked which ones might be non-attaching or electropositive. We found 16 actually existing chemicals and made up two plausible new ones. We believe you can build 0vbb-search TPCs filled with these instead of xenon. 7/

Doing some background reading, I stumbled across one of the exactly 15 nuclear physics papers that tried, and failed, to make "negaton" happen ⚛️🧪☢️
Paper title/abstract: "Negatons and conversion electrons from the decay of 96Nb".  Authors from Uppsala.  Date 1968.Graph of papers by date from Inspirehep.  One blip in 1957, 15 clustered in five years in the late 60s, three more (later two with a different string-theory meaning I think) between then and 2023.

TIL that AT&T's big postwar buildout of long distance telephone cables involved burying thousands of miles of a kind of fancy low-loss coaxial cable I've only encountered in research labs: air-insulated hard-line. "L carrier" was still running (alongside microwave relays) in the 1970s.
Cross-sections of two bundles of coaxial cables.  A mix of air insulation gaps and plastic spacers are visible in the cables.  Big bundle on the left with 20 cables in two rings, small bundle on the right with  12 cables in one ring.   Source https://archives.long-lines.com/mfoster/System.htm

In one story in The House at Pooh Corner, Owl is homeless after a storm: he's a public charge, a refugee, an asylum seeker. I love this passage: where Pooh grasps his moral duty towards Piglet after Piglet gives Owl his own house. Anyway! I spent today imagining what awaits Stephen Miller in hell
“Well,” he said at last, “it’s a very nice house, and if your own house is blown down, you must go somewhere else, mustn’t you, Piglet? What would you do, if your house was blown down?”

Before Piglet could think, Pooh answered for him.

“He’d come and live with me,” said Pooh, “wouldn’t you, Piglet?”

Perhaps she'd like to read Redcliffe Salaman's supposedly classic "The History and Social Influence of the Potato" (1949). From the preface:
"Whether it was mere luck, or whether the potato and I were destined for a life partnership, I do not know, but from that moment my course was set, and I became ever more involved in problems associated directly or indirectly with a plant with which I then had no particular affinity, gustatory or romantic."
