A great example of the magnificent views along the California coast. What a great perk to go along with your time at KITP.

The Cosmology Researcher Talks database hit a milestone today of 10,000 links to publicly available talk/lecture videos, with data from 212 sources. 2020s avg is 1,218 /yr.

It's a fun project & a good way for me to learn more, I'm pleased if it's useful to you.

Thanks! Appreciate the slides. Your 2501.08374 paper of that same title was also a helpful paper when reading up on this topic recently. Hope there's some discussion about this here, may have a follow-up later.

Your Dec 2025 Neutrinos from Home talk beginning at youtu.be/OxjUAne79M4?... for the next 5+ minutes helped me understand better your point after first reading this paper and a couple others on cosmology and neutrino masses. Appreciated talk comments on ways to sort this out, e.g., with DUNE, JUNO.

Thoreau Was Actually Funny as Hell When I was 14 my mother, exasperated by the onset of my teenage angst, handed me a Penguin paperback of Thoreau’s Walden and said, “Read this. The guy who wrote it was a rebel like you.” For some r…

Yeah, agree it's unfair to say he "did without" humor, though much of it may be sardonic. This Walden quote made me LOL:

“Every generation laughs at the old fashions, but follows religiously the new.”

There was even this Literary Hub article about it: Thoreau Was Actually Funny as Hell

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...

Why Do We Love Henry David Thoreau? An examination of the writer’s moral sensibility and how “Walden” fits into our national conscience.

Pulitzer Prize winner Kathryn Schulz dared to redress the Walden mystique, joking she needed a witness protection program for safety. Her critique was called a "wildly intelligent, biting, and hilarious reconsideration" of Thoreau

I suggest Mark Twain as more essential Americana reading

Nice surprise - the TIFR Cosmology and Astroparticle Physics group hadn't posted any State of the Universe seminars since early 2025, but today they posted their videos since then

A couple video links currently aren't working but it's likely the updates are still in process & will be available soon

Neutrinos from Home 2025 - YouTube

Neutrinos from Home online conference was held Dec 2 - 5. A 29-talk playlist was posted the day it ended - a note of thanks to organizers for such quick availability

At least one of the talks was given by a bsky participant: @jazzwhiz.bsky.social - Neutrino Oscillations in the Three Flavor Paradigm

The LeCosPA channel today released a 9-talk playlist from the Opening Symposium of the Max Planck-IAS-NTU Center in early Sept

Videos playlist:

Previously they released the slides at the event's indico site: indico.cern.ch/event/155249...

YouTube video by Research Talks (from Home) Elena de la Hoz - LiteBIRD SGF: constraining isotropic cosmic birefringence

Parity Violation from Home 2025 today released a 32 talk playlist from their Nov 18 - 21 conference

Domain walls in the cosmological context of the early universe, e.g. as discussed e.g. in Simone Blasi's talk, are a different topic than domain walls in magnetic materials. See en.wikipedia.org/wiki/Domain_...

Another useful tool to identify/probe highlights & get timestamps in 1 or more yt videos is gistr.so. Like NotebookLM, can mix in PDFs & webpages along with video(s) as sources. Unlike NotebookLM, watch the video, take notes, explore topic timestamps, etc all in same browser window.

A wide variety of newly publicly available #cosmology talks since just Nov 1

Links to them all continually updated at the Cosmology Researcher Talks database app at jrdmb.netlify.app/crt.html

Dogs too? An anecdote:

"Here's your regular Sunday morning treat" (msg: we're going out to breakfast and you're not coming)

A Sunday first: "We're taking you with us today"

Following Sunday: "Here's your treat"

Dog rejects treat, knows he's not going if he takes it, eyes & posture say let's go

A quick mention that Dillon Brout gave the first public talk on this new paper and the H0 Distance Network today at the CfA ITC luncheon

@styrofoamplates.bsky.social - as one of the authors, if you give a public talk on it or know of others, please post

Now using Obsidian for markdown notes, so looked for good examples covering its features => AstroWiki, study notes for MIT Astrophysics Oral Qualification Exams. Available as GitHub repo and website, d/l it for your own edits.

A favorite for its colors, composition, and calming effect

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.

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.

Dragan Huterer's DESI 3-Year Analysis talk yesterday at EuCAPT Virtual Colloquium

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
