Here's another #TTFIMH Lagrunge point: one of several locations in a planetary (or analogous) system, at which dust and dirt accumulate.

If you recognize this tune, please tell me. (I may not have the right key, and there may be errors or missing notes. The words weren't in English. It has been more than 50 years since I heard it.) jonsinger.org/music/special/… sheet music: jonsinger.org/music/special/…

#TTFIMH I'm imagining the collaboration between CERN and BNL on Quark-Gluon Plasma as if it had been initiated by a phonecall from Geneva to Brookhaven [puts on best Peter Lorre voice] -- "RHIC! RHIC! You've got to help me, RHIC!"

#TTFIMH (this one is particularly technoid) -- A while ago I went to solder something, and ran into a snag.

I'm reading a Phys article, which notes that there was no contact with Orion when it was behind the moon. I am unsettled by a photo of the earth with the caption: This handout from NASA shows earth taken from NASA's Orion spacecraft while behind the moon on Monday, Nov. 21, 2022.

Here's a #TTFIMH item, as usual having no actual significance. Sign in the window of a grocery store in a purple sea urchin neighborhood: Kelp Wanted

Here's another #TTFIMH item. (I tried to check this, to find out how many people had already done it, but officious stupid AI got in the way. Grrr.) Sous video (A watched pot doesn't need to boil.)

I've posted a plant ID query (involving a Japanese maple) on Patreon. (As usual, anyone can read it and respond to it. I almost never restrict access to my postings there.) patreon.com/posts/68617671

#TTFIMH It seems to me that the people at @AnkerOfficial are missing a fine opportunity by not calling one of their chargers the Anker Watt.

Here's another silly #TTFIMH item: Sleep knits up the raveled sleeve of your sweater, if you're a somnambulist.

If you are planning on attending, and you are thinking about getting a room at the hotel, please do that now -- they need to fill their block to avoid some significant problems, and the deadline is the 27th.

Pleasant news from @NASAJPL about the Ingenuity rover leads me to conclude that after two or three more flights it will be able to say "Get thee behind me, Séítah."

I've been thinking about posting some of my pet peeves on the Patreon, but I haven't managed yet. In the meanwhile, here's a good way to avoid one of them: LOSE is the opposite of FIND. [4 letters] LOOSE is the opposite of TIGHT. [5 letters]
