"Weird how it's just clay in one person's hands and art in another's" And sometimes magic happens in combination - e.g., bringing in Dolly transformed a song that Kenny Rogers no longer liked into one of the greatest duets ever www.smoothradio.com/features/the... www.youtube.com/watch?v=UaNG...

A closup view of Bixby Bridge on California's coastal highway in the Big Sur area south of Monterey as the morning fog is starting to lift. The view shows the bridge spanning a deep canyon over the coastal hills with a glimpse of the Pacific Ocean shown in the upper right. The hills are covered with coastal sage scrub. The mood is quiet and peaceful.

2/2 A few quotes from the article in attached image I enjoyed reading Walden, though in the American Transcendentalist literary movement, I'd consider Emerson as the more central figure. The Thoreau Farm organization took issue with Schulz's article at thoreaufarm.org/2015/10/a-re...

Use Case: Quickly identify what was said about :topic in list of multiple yt talk videos (e.g., at a conf), including timestamps to those segments Tip: Use google's NotebookLM, add talk urls to a notebook, then ask your questions. The AI uses the transcripts as source to provide the output.

Dragan Huterer's DESI 3-Year Analysis talk yesterday at EuCAPT Virtual Colloquium cds.cern.ch/record/2945960 A little teaser at 43:27: Are the LCDM tension & Hubble tension related? His take is no, they're different, from segment "5 facts about hints for DDE (and Hubble tension)" starting 38:26
A slide from Dragan Huterer's talk where his take is that the LCDM tension and Hubble tension are different: "No apparent relationship (afaik)". One factor he mentions on the slide is that the Hubble tension gets worse in the w0waCDM model.

Late spring evening walk at sunset uphill to the rock labyrinth that a local rock club created about 10 years ago. A large white oak tree overlooks it. Mount Diablo is barely visible in the background. Great views of the Diablo valley from up here.

Just want to say how much I enjoy the beautiful natural scenes that so many post here. One of mine is these rock cavities called tafoni, photo from Pescadero Beach, south of SF. Thanks @whereisyvette, @ultrawimp, @mcnees, @cburgescliff and others too numerous to name for your frequent scenic photos

Oh yes there is! 😄

If you see this, post a picture taken in the mountains. Rubicon Trail, southwest side of Lake Tahoe

Spectacular campus photo, which reminds me of another autumn campus photo you posted years ago elsewhere. Reposting here because it's awesome. "I see this good girl Bella on campus a couple times a week, and I love her. She weighs in at about a dollar forty." (McNees, 2018)
140 pound Bella, a Newfoundland dog, lies on the green grass in the foreground with trees in the background in spectacular full autumn reddish-orange color on a university campus.

Ok, I'm game, the ones you and the others posted are stunning, this one is maybe just average in comparison

Had a great time visiting Heather Farms yesterday, a beautiful 102-acre community park in the SF East Bay. That's Mount Diablo in the background.

Just plain nuts!
